It is high time to update a bit on the lab work I've been doing with fruit flies. First and formost fly work is fairly time demanding because they are constantly growing, reproducing and thus need a lot of care. To start things out let me introduce their larvae in the form a a video. Here they are on agar/fruit juice plates eatting and as you might suppose - growing!
(*Note I am in the process of changing the larvae video-> please check back!)
I've decided they are rather cute and thus I'll include the David Bowie music video that I think fits their movements well!
Still more research news but not about bats (granted I am making preparations to go to the field soon)....
I am excited to report that my paper on Sonoran Desert rodent diets is accepted for publication and will be published by the journal Oecologia.
This paper reports my findings using stable isotopes of Carbon to track the use of cacti and other plants such as grasses (C3 plants) by several different species of rodents. Research was done at the amazingly beautiful Organ Pipe Cactus National Monument that boasts beautiful cacti and many migrant bird species.
It is exciting to know this work will be published and we even suggested a really cool photo for the cover showing woodrat (Neotoma) tunnels chewed into a saguaro cactus. Fingers crossed!
You can see the location of the ecosystem classified as Sonoran below.
Description (from UT):The Freshman Research Initiative offers first year students the opportunity to initiate and engage in authentic research experiences in chemistry, biochemistry, nanotechnology, molecular biology, physics, astronomy and computer sciences while being supported and mentored by faculty and graduate students. The FRI creates new scientists like no program before it and at a scale that has never been attempted. It provides an authentic research experience and all its benefits to a large number of students early in their careers. It completely transforms students' lives by empowering them to conduct and contribute to modern science—design experiments, perform data analyses and publish peer-reviewed papers—as freshmen. They start becoming innovators their first year.
July 2015**Update: our paper is out and we have engaged in a discussion with Marques, Garcia, and Ames. See their letter here and ours here!
Exciting news is that my favorite journal Trends in Ecology and Evolution lovingly known as just 'TREE' by many just accepted my paper written with my postdoc adviser about sperm storage and how it is defined!
Look for it in May (online at least). Keep your eyes here and it should show up...
While you wait the main take home messages:
storage is ubiquitous in internal fertilizing animals.
understand the evolution of sperm storage we must study adaptations that
result from selection on males separate from those that result from
selection on females.
for sperm storage in males can facilitate sperm storage inside the females.
consideration of different criteria to demonstrate sperm storage will
allow for more comparative studies.
a sperm storage index that will inform such evolutionary studies.
