- [00:00:00.000](lively percussion and piano music)
- [00:00:24.479]Welcome to the 2016 School of Natural Resources
- [00:00:27.884]Elevator Speech Contest.
- [00:00:30.228]I'm John Carroll, Director of the school.
- [00:00:33.556]We in the science world often confuse
- [00:00:36.425]being serious and professional
- [00:00:39.051]with being sort of boring.
- [00:00:42.058]Science conferences often have audiences
- [00:00:45.058]who act like they are at a classical music concert.
- [00:00:50.226]All right, tonight we're not going to do that.
- [00:00:54.087]Tonight we're gonna go for the rock concert
- [00:00:57.778]or something along those lines
- [00:01:00.404]in terms of our audience partipation.
- [00:01:05.323]I'm Matt Joeckel.
- [00:01:06.724]How are you all doing tonight?
- [00:01:08.651](audience responds)
- [00:01:09.609]Thank you, that's great.
- [00:01:10.442]I'm not, thank you for asking.
- [00:01:12.342]Glad you're all here.
- [00:01:14.281]It's a great event.
- [00:01:15.114]I notice even I have a biography in here.
- [00:01:17.900]And I'll read from it to you.
- [00:01:20.032]It says here, "He is an outstanding scientist
- [00:01:22.530]"with a long history of working on important issues
- [00:01:25.234]in the state of Nebraska."
- [00:01:26.632]Who writes this copy?
- [00:01:27.910]That's what I wanna know.
- [00:01:29.633]Well I'm flattered.
- [00:01:31.602]I'm happy to be here tonight.
- [00:01:33.661]Before we actually get into the competition,
- [00:01:35.141]first I wanna ask is,
- [00:01:36.416]are all the people who are doing timing and judging
- [00:01:38.474]and other stuff ready?
- [00:01:41.184]So, while Mark's leading 'em up,
- [00:01:44.638]we'll kind of shake it off here.
- [00:01:45.998]We're gonna have our undergraduates first.
- [00:01:48.835]There's an old African proverb that goes,
- [00:01:51.525]"If you think you're too small to make a difference,
- [00:01:54.401]"try sleeping in a room with a single mosquito."
- [00:01:57.529]It's not the quantity that matters,
- [00:01:59.456]it's the quality.
- [00:02:00.857]And that's why I chose to do qualitative research
- [00:02:04.031]on the human dimensions
- [00:02:05.839]associated with environmental issues.
- [00:02:08.548]The purpose of my research was
- [00:02:10.354]to uncover and address the barriers
- [00:02:12.980]that are preventing students right here at UNL
- [00:02:15.816]from achieving sustainability.
- [00:02:18.117]Now, when we hear the word barrier,
- [00:02:20.006]we think of something big,
- [00:02:21.809]something in the way,
- [00:02:22.997]things like dams or mountains, or, more recently,
- [00:02:26.327]that wall that Trump wants to build, right?
- [00:02:28.825]While all of these are correct,
- [00:02:30.965]I'm talking about behavioral barriers,
- [00:02:33.762]the things that affect the way we think
- [00:02:36.107]and, in turn, influence how we act.
- [00:02:38.914]In order to uncover these barriers,
- [00:02:41.133]my team and I asked 50 students
- [00:02:43.397]a series of in-depth interview questions
- [00:02:46.104]involving the factors influencing
- [00:02:48.281]their sustainable habits on campus.
- [00:02:50.953]After analyzing these interviews,
- [00:02:53.137]we were able to uncover the nine main barriers
- [00:02:56.750]to sustainable behavior
- [00:02:58.469]as well as the percentage of students interviewed
- [00:03:01.230]that are affected by each.
- [00:03:03.165]Now, the very last question we asked each student was,
- [00:03:07.268]"Do you think your actions alone can make a difference?"
- [00:03:11.050]And 100% of those interviewed said no.
- [00:03:14.499]This pertains to the barrier of efficacy
- [00:03:16.926]seen in the center.
- [00:03:18.485]So, now how do we address this barrier
- [00:03:21.276]and the remainder of the other barriers as well?
- [00:03:24.323]My team and I have recently been working with facilities
- [00:03:27.451]on campus to create a social marketing campaign
- [00:03:31.280]that aims to address the awareness
- [00:03:33.463]and skepticism behind these sustainability issues
- [00:03:37.360]by showing students how they can both individually
- [00:03:40.690]and collectively make an impact on campus.
- [00:03:44.303]Whether that be by increasing the total amount
- [00:03:47.183]of recycled material,
- [00:03:48.749]which is currently around 36%,
- [00:03:51.709]or decrease the 9,000 pounds of food waste
- [00:03:55.233]our five dining halls generate every week.
- [00:03:59.098]Our campaign strategy involves
- [00:04:00.990]the use of promotional appealing messages
- [00:04:04.235]that not only show students how they can make a difference,
- [00:04:07.689]but also the results of their efforts.
- [00:04:11.312]If each one of us takes responsibility for our own actions
- [00:04:15.296]and believes that they truly can make an impact,
- [00:04:18.289]we will see changes happen on a campus-wide scale.
- [00:04:22.598]In conclusion, behavior change in humans
- [00:04:25.301]is the real barrier standing between
- [00:04:27.807]the world we live in now
- [00:04:29.451]and a more sustainable planet in the future.
- [00:04:32.618]But we must take these steps now
- [00:04:35.124]to change our actions, alter our mentalities,
- [00:04:38.036]and decrease our ecological footprints
- [00:04:40.426]because the future lies before us
- [00:04:42.722]like a field of fallen snow
- [00:04:44.864]but we must be careful how we tread it
- [00:04:46.917]for every step will show.
- [00:04:48.725]Thank you.
- [00:04:49.827](audience applause)
- [00:04:51.595]Growing up, my summers were spent
- [00:04:53.530]at my my family's cabin by the lake.
- [00:04:55.749]There weren't a lot of other kids around
- [00:04:57.348]so my favorite pastime was turtle catching.
- [00:05:01.166]There was one spot in the lake
- [00:05:02.774]where I knew that the turtles loved
- [00:05:03.857]to line up in the sun on a fallen log,
- [00:05:06.120]and I became so good at catching them
- [00:05:07.971]that I could fill the whole paddle boat up
- [00:05:09.902]to go home and show my mom.
- [00:05:12.001]And at the end of the day,
- [00:05:12.907]we would release the turtles at the end of our dock.
- [00:05:15.917]Every day I did this and every day
- [00:05:19.001]the log was once again full of turtles.
- [00:05:22.008]This got me thinking,
- [00:05:23.906]if I release the turtles off the end of our dock,
- [00:05:26.422]how do they know how to find their way home?
- [00:05:28.890]Now my research focuses on the cognitive abilities
- [00:05:32.882]of aquatic turtles.
- [00:05:34.360]Specifically, what cues do they use
- [00:05:36.544]to find their way from one place to another?
- [00:05:40.454]Until recently, turtles were thought to be unintelligent
- [00:05:43.741]compared to other animals
- [00:05:44.975]because they performed poorly
- [00:05:46.002]in past cognitive studies.
- [00:05:48.271]The problem with those studies
- [00:05:49.625]is that they were performed under conditions
- [00:05:51.394]that might be ideal for a mouse or a cat
- [00:05:54.268]but not conducive to reptiles.
- [00:05:56.525]In some recent studies, tortoises have shown the ability
- [00:05:58.993]to strategize and to learn simple tasks
- [00:06:02.160]by watching other tortoises.
- [00:06:04.305]This is fairly advanced thinking
- [00:06:05.866]that was once thought impossible by reptiles.
- [00:06:09.238]In my research, I've taken aspects
- [00:06:11.010]of these tortoise studies
- [00:06:12.329]and applied them to aquatic turtles.
- [00:06:16.110]My first two trials used mazes.
- [00:06:18.676]The problem with the maze system
- [00:06:20.439]was that the turtles are more interested
- [00:06:22.211]in exploring their new environment,
- [00:06:24.794]than in finding the food at the end of the maze.
- [00:06:27.477]This problem forced me to reevaluate
- [00:06:29.744]and I realized that if I wanted to study a turtle,
- [00:06:32.340]I needed to think like a turtle.
- [00:06:34.686]So, for my current trials,
- [00:06:36.003]I'm using a grid system
- [00:06:37.399]set up on the bottom of each turtle's tank.
- [00:06:39.831]And I feed them in the same location on the grid every time.
- [00:06:43.567]Now, once they've learned where to find their food,
- [00:06:46.191]I will begin changing the cues in their environment
- [00:06:49.344]such as rocks and plants.
- [00:06:51.394]And I'll determine whether or not
- [00:06:53.168]this affects their ability to find their food.
- [00:06:55.751]So far, this system has been much more successful,
- [00:06:58.378]because the trials are taking place
- [00:07:00.143]in the turtle's normal environment.
- [00:07:04.051]Although I'm using snapping turtles for my study,
- [00:07:06.108]the goal is that the this research
- [00:07:07.547]can be applied the conservation of endangered species
- [00:07:09.932]such as the critically endangered Blanding's turtle
- [00:07:12.412]that lives right here in Nebraska.
- [00:07:15.052]Knowing how turtles learn and think
- [00:07:17.400]is important to help conservationists
- [00:07:19.208]design conservation corridors
- [00:07:21.385]that connect fragmented habitat
- [00:07:23.199]and know what these animals need to navigate this new space.
- [00:07:27.817]It's also very important to me
- [00:07:29.913]so that some day
- [00:07:31.021]when my children fill the paddle boat up with turtles,
- [00:07:33.115]and want to know how they'll find their way home,
- [00:07:35.335]this time I'll have the answer.
- [00:07:37.350]Thank you.
- [00:07:38.251](audience applause)
- [00:07:43.700]The cosmic ray neutron method.
- [00:07:46.523]Sounds pretty cool doesn't it?
- [00:07:48.439]It's not bad.
- [00:07:50.158]Now, this is a revolutionary technology
- [00:07:52.162]in mapping soil moisture.
- [00:07:53.837]The golden standard in the approximate five decades
- [00:07:57.847]prior to the cosmic ray neutron method
- [00:08:00.179]was a single point measurement.
- [00:08:02.484]We have that single point measurement
- [00:08:04.039]and we are looking at soil moisture
- [00:08:05.631]based on an entire field.
- [00:08:08.332]With the cosmic ray neutron probe,
- [00:08:09.930]we can look at the soil moisture
- [00:08:11.770]across a thousand foot radius
- [00:08:13.610]and about 30 centimeters into the soil
- [00:08:15.990]and accurately equate that
- [00:08:17.916]to the soil moisture in an entire field
- [00:08:20.246]rather than just one point.
- [00:08:22.128]Now, the problem that we face is a simple one.
- [00:08:26.186]As we increase in our population,
- [00:08:28.025]we have an increase in need for food production.
- [00:08:31.053]Now, when we have that increase
- [00:08:32.970]for food production, we have to find a way,
- [00:08:34.600]how do we increase our yield,
- [00:08:35.823]how do we continue to be able to feed
- [00:08:37.991]the people that we need to feed?
- [00:08:39.346]And we believe that water,
- [00:08:40.778]water is the answer to that.
- [00:08:42.045]So, if we can accurately quantify
- [00:08:43.477]how much water is in the soil where we have our crops,
- [00:08:47.867]then we can optimize how we use that water.
- [00:08:52.216]Now, we have a couple different tools that we use
- [00:08:55.136]when we are using our cosmic ray neutron probe.
- [00:08:58.957]And one of them is this nifty little backpack down here.
- [00:09:01.825]It's the bane of my existence.
- [00:09:04.211]The backpack is about 60 pounds
- [00:09:06.827]and walking around in the corn
- [00:09:08.795]in about 115 degree micro climate,
- [00:09:11.377]not the most comfortable thing to do,
- [00:09:13.755]but it gives us some pretty good data.
- [00:09:15.229]It gives us data on a field scale basis
- [00:09:17.645]like you see down here.
- [00:09:19.366]And we can equate that to,
- [00:09:22.503]again, how much soil,
- [00:09:24.307]or how much water is in the soil in that field.
- [00:09:27.680]And the way we apply that
- [00:09:30.169]to a real world application
- [00:09:32.798]is we can use a technology called variable rate irrigation.
- [00:09:37.470]And we can our water maps that we are creating
- [00:09:39.598]to that technology that farmers are using
- [00:09:43.393]and without our water maps,
- [00:09:45.309]you don't know when or where you need to water.
- [00:09:48.500]But if you apply our water maps,
- [00:09:50.672]then we can increase yield
- [00:09:53.505]by knowing when, where, how much, how little to water
- [00:09:57.056]in that specific field.
- [00:09:58.856]Now, we don't believe that the cosmic ray neutron probe
- [00:10:01.848]is the answer to all of our water issues,
- [00:10:05.242]our food issues, but we absolutely believe
- [00:10:07.284]that it is a step in the right direction.
- [00:10:09.416]Thank you.
- [00:10:10.518](audience applause)
- [00:10:11.896]Let's give another round of applause
- [00:10:13.294]for all of our undergraduate speakers.
- [00:10:21.404]And as we get ready here for the graduate students
- [00:10:24.828]I wanna remind them I have this
- [00:10:27.583]and I'm not afraid to use it.
- [00:10:29.719]Something that has come into many things is a heart.
- [00:10:31.282]I have a heart, you have a heart,
- [00:10:34.244]and, despite what social media tells us nowadays,
- [00:10:36.134]even most politicians have a heart.
- [00:10:38.076]Well, for ecotourism (laughs),
- [00:10:41.121](audience laughs)
- [00:10:43.918]Well, for ecotourism,
- [00:10:44.751]an environmentally and culturally responsible
- [00:10:46.533]form of tourism,
- [00:10:47.516]that heart is the ecotour guide.
- [00:10:49.486]Guides play a very important role.
- [00:10:51.005]They educate guests, keep them safe,
- [00:10:52.816]and make sure they have an enjoyable experience.
- [00:10:55.200]They also play a key role in minimizing
- [00:10:56.837]the negative environmental impact of tourism.
- [00:10:59.553]However, there is very little research
- [00:11:01.278]outlining what types of training
- [00:11:02.558]best prepare guides to play all of these roles.
- [00:11:05.307]This past summer, I took on that challenge.
- [00:11:07.448]I traveled to South Africa to research EcoTraining,
- [00:11:10.617]one of the oldest and most reputable
- [00:11:12.010]guide training programs on the continent.
- [00:11:14.652]While I was there, I had the opportunity
- [00:11:16.060]to go through a guide training course
- [00:11:17.622]seeing first hand how guides learn
- [00:11:18.898]how to handle everything from angry elephants
- [00:11:21.036]to grumpy guests.
- [00:11:23.055]I also had the opportunity to conduct surveys with
- [00:11:24.944]and interview trainers, current and former students.
- [00:11:29.212]Through this qualitative and quantitative data,
- [00:11:31.027]I was able to gain valuable insight
- [00:11:32.678]into the training philosophy
- [00:11:34.537]and the methods adopted by EcoTraining
- [00:11:36.562]as well as the outcomes and limitations
- [00:11:37.919]of their program.
- [00:11:39.155]I'd like to share a couple of those key findings with you.
- [00:11:42.362]First of all, EcoTraining students do not spend their days
- [00:11:45.340]sitting in lectures.
- [00:11:46.308]They spend six to eight hours a day out in nature
- [00:11:48.685]using all of their senses, including taste,
- [00:11:51.184]to learn their trade.
- [00:11:52.498]Trust me, you'll never forget why most animals
- [00:11:54.384]do not eat silver cluster leaves
- [00:11:55.901]after you've chewed on a couple.
- [00:11:59.021]Another key characteristic
- [00:12:01.153]of EcoTraining's program are it's instructors.
- [00:12:03.498]During a course, students have up to
- [00:12:04.895]13 different instructors.
- [00:12:06.500]Each one is different but all are highly passionate
- [00:12:08.679]and experienced guides.
- [00:12:10.036]My instructors were so good at their job
- [00:12:11.560]that they can make us as excited
- [00:12:12.754]about species like lichen or millipedes
- [00:12:14.978]as we were about elephants and lions.
- [00:12:17.989]Spending time with these instructors
- [00:12:19.012]in this amazing environment
- [00:12:20.081]has a huge impact on students.
- [00:12:22.178]More students reported having a stronger connection
- [00:12:24.363]to nature and a stronger desire
- [00:12:25.892]to protect it after training.
- [00:12:28.441]These impacts were also evident in the survey data.
- [00:12:30.497]I found that once they become guides,
- [00:12:32.105]most students practice environmentally responsible behaviors
- [00:12:34.588]most or all the time.
- [00:12:36.029]I also found a statistically significant correlation
- [00:12:38.249]between transformational leadership scores
- [00:12:40.725]and or guiding competency scores
- [00:12:42.662]suggesting that once students succeed in training,
- [00:12:45.523]they have a high potential for becoming leaders
- [00:12:47.130]in their field, capable of influencing
- [00:12:48.656]the environmental ethics of other guides
- [00:12:50.387]and their tourists.
- [00:12:52.615]So, based on my research,
- [00:12:53.931]it is clear that EcoTraining's program produces
- [00:12:55.814]competent guides that are motivated
- [00:12:57.288]to put their heart into their career.
- [00:12:59.269]This research is very important
- [00:13:00.669]because if we can uncover how to create
- [00:13:01.940]more training opportunities like this one,
- [00:13:03.871]we will be able to keep the heart
- [00:13:05.103]of this environmentally responsible industry beating strong.
- [00:13:07.617]Thank you.
- [00:13:09.138](audience applause)
- [00:13:11.256]All right, thank you.
- [00:13:12.450]So, I study the factors that affect recreational fishermen,
- [00:13:15.506]or angler, fishing location within a water body.
- [00:13:18.935]To improve angler satisfaction,
- [00:13:21.126]we first need to understand where and why anglers fish.
- [00:13:24.831]Now, a satisfied angler is an angler
- [00:13:26.689]that's gonna return year after year
- [00:13:28.254]and purchase a fishing license.
- [00:13:30.024]And that translates into funds for conservation.
- [00:13:32.906]So, if we improve angler satisfaction,
- [00:13:35.002]we increase funding for conservation.
- [00:13:37.921]So, a simple explanation might be
- [00:13:39.971]that anglers choose to fish,
- [00:13:41.412]either where there are fish
- [00:13:43.055]or where they catch fish.
- [00:13:45.071]So, in these scenarios we would expect
- [00:13:47.210]that within a water body,
- [00:13:48.609]if we were to look at the distribution of anglers,
- [00:13:51.238]it would match the distribution of fish or catch rates.
- [00:13:55.306]However, multiple studies have shown,
- [00:13:57.971]that even after we take into account differences in skill
- [00:14:02.054]and an imperfect knowledge of where fish are,
- [00:14:05.344]anglers do not match distribution of fish.
- [00:14:09.583]So, instead I decided to tackle the question of catch rates.
- [00:14:12.664]And I did this in a put and take fishery.
- [00:14:15.384]In a put and take fishery,
- [00:14:17.522]recreationally sought-after, catchable size fish
- [00:14:20.441]are stocked, or put, for recreational anglers to take.
- [00:14:25.994]Now, if you look behind me to my upper right,
- [00:14:28.049]you'll see our water body.
- [00:14:29.451]The darker areas represent where higher rates
- [00:14:32.784]or more fish per hour were being caught.
- [00:14:35.334]The lighter areas represent fewer fish per hour.
- [00:14:38.085]And those blue dots represent
- [00:14:39.812]where the anglers were during this time.
- [00:14:42.081]Now, the anglers watched the fish go into the water body
- [00:14:44.595]and they're able to watch other anglers
- [00:14:46.405]on that water body catching fish.
- [00:14:48.544]So, they can use that information
- [00:14:50.068]on other anglers' catch rates
- [00:14:51.790]to decide where they wanna fish.
- [00:14:53.641]However, even though most anglers appear to be distributed
- [00:14:56.561]where we think they would be with high catch rates,
- [00:14:58.573]a substantial number are in less than ideal locations.
- [00:15:01.819]As we move through time
- [00:15:03.216]and our catch rates they start to become equivalent
- [00:15:05.434]throughout this water body,
- [00:15:06.669]we see that more and more anglers
- [00:15:08.606]are redistributing themselves.
- [00:15:11.849]Now, this isn't surprising when we consider
- [00:15:13.987]what's going on here.
- [00:15:14.987]Recreational angling is just that.
- [00:15:17.284]It's recreation and the point of recreation
- [00:15:19.214]is to gain satisfaction.
- [00:15:21.150]And while it's obviously satisfactory for an angler
- [00:15:23.746]to catch a fish, it isn't the only factor.
- [00:15:26.902]Other factors, including fishing
- [00:15:28.515]in a pleasing, aesthetic environment
- [00:15:30.439]or fishing further away from other anglers
- [00:15:32.824]to gain a sense of solitude are also important.
- [00:15:35.905]Now, each individual angler
- [00:15:37.346]is weighing these different variables,
- [00:15:39.124]and they're trying to maximize their satisfaction.
- [00:15:41.718]We see this because, as the catch rates drop,
- [00:15:43.646]more and more anglers choose to move to a new site
- [00:15:46.524]that maximizes that satisfaction for them.
- [00:15:49.361]So, how do we manage for this?
- [00:15:51.209]We wanna think about how to manage for satisfaction
- [00:15:53.626]and in a put and take fishery,
- [00:15:54.813]the answer is surprisingly simple.
- [00:15:56.619]We can think about stocking multiple locations
- [00:15:58.886]throughout the entire water body
- [00:16:00.528]to increase these catch rates for all anglers
- [00:16:02.916]while allowing them to fish where they prefer.
- [00:16:05.972]In doing so, we can use catch rates
- [00:16:07.908]as a tool for satisfaction
- [00:16:09.757]and increase funding for conservation.
- [00:16:11.528]Thank you for your time.
- [00:16:13.012](audience applause)
- [00:16:15.830]Raise your hand if you've ever caught a fish.
- [00:16:18.231]Awesome, so most of you know the exciting feeling
- [00:16:20.249]of finally reeling in a catch.
- [00:16:21.707]What do you think about?
- [00:16:23.114]If you're a skilled angler,
- [00:16:24.062]you're probably thinking about the fight.
- [00:16:26.168]If you're like me,
- [00:16:27.072]you're probably just excited
- [00:16:28.223]that there's something other than bait
- [00:16:29.500]at the end of your line.
- [00:16:30.965]But, do you ever contemplate what drove that fish
- [00:16:32.532]to take the bait?
- [00:16:33.813]Was it hungry, was it naïve?
- [00:16:35.631]What about it's personality?
- [00:16:37.776]Laugh if you want, but fish have personalities.
- [00:16:40.209]It might not be like yours or mine,
- [00:16:41.988]but they exhibit repeatable behaviors across contexts.
- [00:16:44.961]And these behaviors
- [00:16:47.951]are best measured on a boldness continuum.
- [00:16:50.133]So, some fish are more bold, active and aggressive,
- [00:16:52.857]and others are more shy, inactive and timid.
- [00:16:57.473]So, who cares?
- [00:16:58.306]Why does it matter if fish have personalities?
- [00:17:00.442]Well, there's a lot of reasons
- [00:17:01.801]but I'm gonna focus on a few.
- [00:17:02.997]First, bold fish are more likely to be caught by anglers.
- [00:17:06.628]And this is important because if we're selecting
- [00:17:08.602]for a specific personality by removing bold fish
- [00:17:11.366]more often than shy fish,
- [00:17:12.807]then might ultimately end up with populations
- [00:17:14.633]full of shy fish.
- [00:17:16.410]This can have a lot of implications
- [00:17:17.816]for population dynamics like reproduction.
- [00:17:21.397]Additionally, it's thought that bold inviduals
- [00:17:23.665]might be better dispersers.
- [00:17:25.641]So, in light of things like climate change,
- [00:17:27.187]we may be harming the population by removing individuals
- [00:17:29.854]that are more likely to colonize elsewhere.
- [00:17:37.054]If those aren't enough reasons
- [00:17:38.537]to care about whether or not a fish is bold or shy,
- [00:17:41.252]what if I told you that an individual's personality
- [00:17:43.599]may affect the outcome of your next fishing trip?
- [00:17:46.307]Research shows that catch and release oriented
- [00:17:49.208]sport fish populations
- [00:17:50.366]may alter their behavior to avoid future capture.
- [00:17:53.152]And if this is true,
- [00:17:53.985]if fish are altering their behavior
- [00:17:56.080]to avoid the negative stimulus of being caught and released,
- [00:18:00.008]then perhaps this has something to do
- [00:18:02.178]with their personality.
- [00:18:03.458]If a bold fish is more likely to get caught,
- [00:18:05.728]is it also more likely to get repeatedly caught?
- [00:18:08.157]What about shy fish?
- [00:18:09.555]These are the questions that my Master's research
- [00:18:11.246]is hoping to shed some light on.
- [00:18:13.514]To do this, we set up a series of experiments
- [00:18:15.283]in the lab with individual rock bass
- [00:18:17.307]and they go through behavioral tests
- [00:18:19.248]to determine their individual personalities.
- [00:18:21.436]Then they're fished over seven consecutive days
- [00:18:24.323]to see if they alter their behavior
- [00:18:26.099]to avoid the negative stimulus of being caught.
- [00:18:31.234]We hope to see, we're using different treatments
- [00:18:34.172]so, in some cases we have wax worms
- [00:18:36.273]and in some cases we have a lure with a wax worm
- [00:18:38.218]to attempt to tease out
- [00:18:39.620]what complicates and what facilitates learning.
- [00:18:42.703]Additionally, we're looking at hunger
- [00:18:44.752]to see it's overall role in the process.
- [00:18:47.056]Hopefully at the outcome of my research,
- [00:18:48.617]we'll have a better idea of how these individuals respond
- [00:18:51.960]to the negative stimulus of being caught and released.
- [00:18:54.518]Whether or not that has anything to do
- [00:18:56.631]with their individual personalities
- [00:18:58.652]and maybe the next time you go fishing,
- [00:19:00.470]you'll be a little bit more curious
- [00:19:01.876]about what drove the fish on the end of your line
- [00:19:03.568]to take the bait.
- [00:19:04.933]Thank you.
- [00:19:05.766](audience applause)
- [00:19:08.377]Very, very nice.
- [00:19:10.208]Let's give it up for all of our Master's candidates here.
- [00:19:13.917](audience applause)
- [00:19:20.857]We're going on to our PhD students, and hi.
- [00:19:25.108]Challenge only becomes an obstacle when you bow to it.
- [00:19:28.247]I love this quote and it applies to many things in life.
- [00:19:31.800]As an insect biologist, I often get the question,
- [00:19:34.440]"Why do you study those stupid little insects
- [00:19:37.002]when you could study cool mammals or reptiles?"
- [00:19:40.267]But what if I told you
- [00:19:41.669]that a small beetle can better cope
- [00:19:43.111]with climate change and pollution than us humans?
- [00:19:45.721]And by studying them, we can use their strategies
- [00:19:49.109]to solve our problems.
- [00:19:51.085]Let me tell you how.
- [00:19:53.025]Imagine that you're a small beetle
- [00:19:54.920]and you have to fight over food in order to stay alive.
- [00:19:56.939]Now, in front of you is a pool
- [00:19:58.918]full of delicious dead insects.
- [00:20:01.224]The problem?
- [00:20:02.169]It's a thermal pool in Yellowstone National Park
- [00:20:04.486]of about 160 degrees fahrenheit
- [00:20:06.961]and full of toxic heavy metals like lead and mercury.
- [00:20:10.602]But if you you're able to survive,
- [00:20:12.246]you can enjoy an all-you-can-eat buffet.
- [00:20:15.202]Quite the challenge, isn't it?
- [00:20:16.685]Well, that's exactly what the Wet Salts tiger beetles
- [00:20:19.001]were able to do.
- [00:20:20.199]But how in the world are they able to survive
- [00:20:22.386]in this water?
- [00:20:23.719]It's a unique behavior that's never been documented before
- [00:20:26.672]and discovering its secrets will be my challenge.
- [00:20:30.302]This summer I'll be going to Yellowstone National Park
- [00:20:32.825]to investigate this.
- [00:20:34.141]So, basically imagine me laying on the ground
- [00:20:36.783]observing these beetles for hours
- [00:20:38.722]in an area full of bears, bison, wolves,
- [00:20:41.613]and steaming hot water.
- [00:20:43.798]So, yeah, health insurance.
- [00:20:46.145](audience laughs)
- [00:20:48.211]One technique the beetles might use to prevent overheating
- [00:20:50.726]is the use of a water bubble.
- [00:20:52.586]If you take a close look at the top left picture,
- [00:20:55.141]you might be able to see a water bubble
- [00:20:56.794]underneath the beetle's body.
- [00:20:58.696]It reduces heat, similar to when humans sweat
- [00:21:01.048]to release heat.
- [00:21:02.371]A different possibility is the use of
- [00:21:04.227]heat shock proteins shown in the bottom figure.
- [00:21:07.704]On the left you have a normal folded protein.
- [00:21:10.104]And with extreme temperatures it will unfold.
- [00:21:13.072]Then heat shock proteins are released
- [00:21:14.560]and they will attach to this protein
- [00:21:16.457]and help it refold again,
- [00:21:17.858]therefore restoring the cell's function.
- [00:21:20.833]Humans also have heat shock proteins
- [00:21:22.855]and through unraveling the mystery for the beetles,
- [00:21:25.080]we could reduce the risk of overheating for humans as well.
- [00:21:29.704]Also, heavy metals are very bad for the environment
- [00:21:32.846]and through learning how these beetles can cope
- [00:21:34.860]with these extreme levels,
- [00:21:36.220]we could reduce the risk to our environments.
- [00:21:39.099]Then lastly, climate change is causing some areas
- [00:21:41.523]to get warmer, some colder, some drier,
- [00:21:43.949]and others more wet,
- [00:21:45.472]and if we look for animals with similar traits
- [00:21:47.537]and behaviors to the the Wet Salts tiger beetles,
- [00:21:49.845]we could predict which animals can better cope
- [00:21:52.115]at higher temperatures
- [00:21:53.679]and, therefore, allocating the right funding
- [00:21:55.831]to help save the right animals.
- [00:21:58.997]A challenge only becomes an obstacle when you bow to it.
- [00:22:02.344]These beetles were able to overcome a huge challenge.
- [00:22:05.433]So, my question is,
- [00:22:07.244]are we going to let climate change and pollution
- [00:22:09.507]become an impossible obstacle to us?
- [00:22:12.355]I say, "Hey, challenge, bring it on."
- [00:22:16.686]Thank you.
- [00:22:17.631](audience applause)
- [00:22:19.742]You're probably all familiar
- [00:22:21.145]with the canary in the coal mine.
- [00:22:23.349]If miners notice that their caged canary coworkers
- [00:22:25.996]kicked the bucket while they were under ground,
- [00:22:27.936]they knew it was time to get the hell out of Dodge or die.
- [00:22:31.360]I am most passionate about identifying and understanding
- [00:22:34.044]the patterns of nature that occur in areas
- [00:22:35.567]where humans thrive, cities.
- [00:22:38.498]Generally, my research asks questions like,
- [00:22:40.468]which wildlife species die, survive, or thrive
- [00:22:43.960]in urban areas and why?
- [00:22:46.474]To approach questions like this,
- [00:22:48.005]I work with a delightful, yet gang-like
- [00:22:50.328]group of bird species some people like to call trash birds.
- [00:22:54.047]And you probably already guessed it,
- [00:22:55.575]my favorite trash bird species is the House Sparrow.
- [00:22:58.876]Now, historically, the House Sparrow has thrived
- [00:23:00.975]wherever humans are.
- [00:23:02.378]From your family farm to the downtown McDonalds dumpsters,
- [00:23:05.932]they were there.
- [00:23:07.212]However, the House Sparrow seems to be losing its ability
- [00:23:09.892]to coexist alongside humans.
- [00:23:12.111]Over the past 20 or 30 years,
- [00:23:14.059]the House Sparrow has been declining in cities worldwide
- [00:23:16.666]and researchers just don't know why.
- [00:23:19.189]Have any of you heard that old joke,
- [00:23:21.486]"How many PhDs does it take to screw in a light bulb?"
- [00:23:24.205]Well, in the case of the declining House Sparrow,
- [00:23:27.052]it's taken at least 30 years worth.
- [00:23:29.191]My Master's thesis research at the University of Florida
- [00:23:31.916]took me down that path,
- [00:23:33.282]trying to understand why they're declining in cities.
- [00:23:36.084]Generally, I found that House Sparrows aren't doing
- [00:23:38.504]so good in our backyards.
- [00:23:40.030]And I found evidence suggesting
- [00:23:41.675]that House Sparrows may be responding negatively
- [00:23:44.185]to an increase in canopy cover.
- [00:23:46.490]In other words, the more trees there are
- [00:23:48.626]in your neighborhood and the bigger those trees are,
- [00:23:50.558]the worse off this bird may be.
- [00:23:53.231]Now, I know that none of us probably agree
- [00:23:55.702]that the House Sparrow is the most majestic species alive,
- [00:23:58.621]but I hope that we can agree that the House Sparrow
- [00:24:00.924]represents something pretty important.
- [00:24:02.864]And that is the ability of other species
- [00:24:04.800]to live alongside us.
- [00:24:06.412]Now, it's really easy to assume
- [00:24:08.348]that we as humans are alone
- [00:24:09.829]in these urban jungles we call cities,
- [00:24:11.596]but we are, in fact, drivers and passengers
- [00:24:14.391]in the many processes occurring in nature,
- [00:24:17.033]and because urbanization directly affects these processes,
- [00:24:20.914]it's vital that we identify
- [00:24:22.478]which wildlife species die, survive, or thrive
- [00:24:26.118]in urban areas and why.
- [00:24:28.431]So, the next time you're feeling disconnected from nature,
- [00:24:31.611]I suggest going downtown, dropping a Dorito on the ground,
- [00:24:35.081]and watching a couple of House Sparrows fight it out
- [00:24:37.539]over that Dorito.
- [00:24:38.819]And ask yourself this question,
- [00:24:40.507]is the House Sparrow the canary in our urban coal mine?
- [00:24:43.682]Thank you.
- [00:24:44.961](audience applause)
- [00:24:46.399]You may not realize it,
- [00:24:47.458]but bats are everywhere in Nebraska.
- [00:24:49.795]They're nestled in the leaves above you
- [00:24:51.355]as you walk down the sidewalk,
- [00:24:52.947]and they're under the dead bark of the tree
- [00:24:54.921]at your favorite fishing hole.
- [00:24:56.686]In fact, Nebraska has 13 species of bats.
- [00:25:00.180]They vary in size, shape and color.
- [00:25:03.140]Some hibernate in mines and caves during winter,
- [00:25:06.509]while others migrate to unknown locations.
- [00:25:11.923]When they return in spring,
- [00:25:13.731]these bats eat up to their body weight
- [00:25:16.159]in insects every night.
- [00:25:18.091]That's the equivalent of you or me
- [00:25:19.982]eating about half a cow's worth of steaks every day.
- [00:25:23.684]Their voracious appetites contribute
- [00:25:26.908]about three billion dollars
- [00:25:28.147]to U.S. agricultural industry in the form of pest control.
- [00:25:32.875]And about 1 billion dollars to worldwide corn production.
- [00:25:36.479]Unfortunately, we may be noticing more buzzing
- [00:25:40.141]in our backyards and seeing more damage to our crops
- [00:25:43.097]in the coming years.
- [00:25:45.072]Experts fear that bat populations
- [00:25:47.702]will be unable to recover
- [00:25:49.035]from the devastating effects of a disease
- [00:25:50.949]called white-nose syndrome
- [00:25:52.501]and the cumulative impacts of wind energy development.
- [00:25:56.694]While renewable energy and wind energy
- [00:25:59.277]are important parts of our future,
- [00:26:01.545]there is no question that wind turbines kill bats.
- [00:26:04.577]In the Great Plains, it is estimated that each turbine
- [00:26:08.193]kills four to eight bats every year.
- [00:26:11.600]The cumulative impact across the United States
- [00:26:14.350]is estimated to be almost one million bats every year,
- [00:26:18.220]a number that is rapidly rising
- [00:26:20.572]as more and more turbines are placed on the landscape.
- [00:26:25.588]It is important to balance our energy needs
- [00:26:28.178]with those of conservation.
- [00:26:31.682]My research asks the simple question
- [00:26:34.854]of when and where bats are migrating.
- [00:26:37.988]Since these species are the most impacted
- [00:26:40.247]by wind energy development,
- [00:26:42.144]answering these questions may help us
- [00:26:44.818]reduce the impact to bats.
- [00:26:49.544]To answer these questions,
- [00:26:51.298]I've placed bat detectors
- [00:26:52.569]that listen for the ecolocation calls of bats
- [00:26:55.319]across the east central Nebraska landscape.
- [00:26:58.197]By examining the activity levels
- [00:27:00.414]in relation to landscape features and weather patterns,
- [00:27:04.109]I hope to discern areas and times
- [00:27:06.619]when bats are most likely to be killed by wind turbines.
- [00:27:10.599]My hope is that this information could be used
- [00:27:13.234]to reduce the threats wind turbines pose to bats.
- [00:27:17.367]For example, if bats migrate along rivers,
- [00:27:19.915]and bluff lines, we can avoid placing wind turbines
- [00:27:23.035]in those areas or shut down turbines
- [00:27:25.303]when bats are most likely to be killed.
- [00:27:28.631]Answering these simple questions
- [00:27:30.279]about the basic biology of bats
- [00:27:32.214]may be the key to saving them.
- [00:27:34.026]Thank you.
- [00:27:35.261](audience applause)
- [00:27:36.561]That's great.
- [00:27:37.394]We're done with our speakers for the evening,
- [00:27:39.518]but I think all of them collectively deserve
- [00:27:41.826]yet another round of applause.
- [00:27:43.551]Let's give it to 'em.
- [00:27:45.073](audience applause)
