Here at WideWorldScience we are proud to announce that the
field component of the lizard project is now being supported by a National
Geographic Society Waitt Grant. The generous
support from this grant will allow Dr. Dan Warner, me, and our collaborator
Alexis Harrison to step up our work in central Florida and reach an even wider
audience of students through innovative educational outreach and partnerships
with classrooms around the country. This
grant will allow us to:
1) Learn more about evolution by natural selection in the
wild.
As the high school students who followed our work in real
time last spring already know, we have an ambitious experiment currently
underway. We are attempting to answer
the question of “What effect does the sex ratio of a population have on natural
selection in that population?” An
animal’s sex (whether it is male or female) is one of its most significant
traits that can determine its ability to survive in a particular setting. For vertebrate animals (like our lizards) in
the wild little is known about how the proportion of males to females affects
the survival of both sexes. What does it
take to survive in a male dominated world? Is that different in a female dominated
world?
To work to answer these questions, we are closely studying
small populations on nine living laboratory islands. Four of the islands have majority female
populations and five of the islands have majority male populations. Each of the founding lizards on these islands
has been carefully measured and marked.
We also have taken DNA samples from the founding lizard population on
each island and plan to track parentage in each successive generation. We will
be looking closely at the sex ratios in each generation, survival rates for
individuals and which sets of traits give an animal the best chance of survival
in the available environments. In short, this work will give us the chance to
answer interesting questions about evolution and sexual selection that have
never been answered before.
2) Bring the experience of field work in evolutionary
ecology into the classroom.
At WideWorldScience, we believe that there is too much
distance between the science students usually learn in school and cutting edge
of research in the field. With the field
component of the Lizard Project, we are trying to bring exciting field work
into the classroom. Students and
teachers from partner classrooms will follow our work through this blog as we
prepare to go into the field. This will
allow for an inside look into the process of science. Students will become familiar with our study
questions, hypotheses and development of our methods. Then as we head out to the islands to check
on our lizards along Florida’s Intra Coastal Waterway, students will stay
engaged through daily Skype chats from the field and frequent blog updates. This will give students the chance to ask
questions live and in real time as they get a window into the process of
science as it happens.
If you are a teacher or a student who would like to be a
part of the National Geographic supported Lizard Project this spring, please
drop us a line at aaronmreedy@gmail.com
Thanks again to the National Geographic Society and the
Waitt Foundation for supporting science and our efforts to bring science to the
classroom!
