Davidson: Animals migrated all over the world, and if we want to

4
00:00:12.000 --> 00:00:16.000
be able to look at those global migrations, and if

5
00:00:16.000 --> 00:00:20.000
we also want to be able to network and compare data

6
00:00:20.000 --> 00:00:24.000
about animal movements and behaviors in different regions, different species

7
00:00:24.000 --> 00:00:28.000
in different parts of the world, and over long periods of time, we really need a global

8
00:00:28.000 --> 00:00:32.000
database for that. So one tool we offer in

9
00:00:32.000 --> 00:00:36.000
MoveBank is called the Environmental Data Automated Track

10
00:00:36.000 --> 00:00:40.000
Annotation System, which we—or for short, EnvDATA,

11
00:00:40.000 --> 00:00:44.000
and this is a free service that lets researchers and the public link

12
00:00:44.000 --> 00:00:48.000
animal movement data to environmental information from

13
00:00:48.000 --> 00:00:52.000
remote sensing products and weather models from NASA and other

14
00:00:52.000 --> 00:00:56.000
providers, including the GPM precipitation data.

15
00:00:56.000 --> 00:01:00.000
And so by connecting these data sources,

16
00:01:00.000 --> 00:01:04.000
we make it much easier for researchers to investigate questions

17
00:01:04.000 --> 00:01:08.000
about how animals’ movements and migrations are affected

18
00:01:08.000 --> 00:01:12.000
by the environment around them. Part of

19
00:01:12.000 --> 00:01:16.000
climate change is a phenomenon called polar amplification, which means

20
00:01:16.000 --> 00:01:20.000
the rate of warming is going to occur more quickly at the

21
00:01:20.000 --> 00:01:24.000
poles, at the North Pole and the South Pole. So, in the Arctic, we’re seeing

22
00:01:24.000 --> 00:01:28.000
warming rates more than twice as high as the global

23
00:01:28.000 --> 00:01:32.000
average. So this is causing really dramatic changes in what animals experience.

24
00:01:32.000 --> 00:01:36.000
In this recent project, led by

25
00:01:36.000 --> 00:01:40.000
Dr. Peter Mahoney at the University of Washington, we looked at how

26
00:01:40.000 --> 00:01:44.000
movement speeds of different animal species change with precipitation

27
00:01:44.000 --> 00:01:48.000
and temperature. And so we looked at data from more than

28
00:01:48.000 --> 00:01:52.000
1700 animals. and we found that movement speeds of wolves.

29
00:01:52.000 --> 00:01:56.000
caribou, bears and moose did not seem to be affected by heavy summer

30
00:01:56.000 --> 00:02:00.000
rains, but that wolves, moose and boreal caribou

31
00:02:00.000 --> 00:02:04.000
moved less where there was higher snowfall in the winter.

32
00:02:04.000 --> 00:02:08.000
We also found that at higher temperatures, some species moved

33
00:02:08.000 --> 00:02:12.000
less while others were moving more, which could impact predator-prey

34
00:02:12.000 --> 00:02:16.000
relationships and the ability to find food as global temperatures continue to

35
00:02:16.000 --> 00:02:20.000
increase and as precipitation patterns change.

36
00:02:20.000 --> 00:02:24.000
We link almost entirely to globally available datasets.

37
00:02:24.000 --> 00:02:28.000
The same methods can be used anywhere in the world.

38
00:02:28.000 --> 00:02:32.000
This means that researchers can make assessments across migratory routes

39
00:02:32.000 --> 00:02:36.000
of species traveling really long distances, make comparisons across

40
00:02:36.000 --> 00:02:40.000
regions and species. And this also makes it easier for researchers in different countries

41
00:02:40.000 --> 00:02:46.784
to work together.
