Congratulations to Courtney Reed for winning big -- two awards in one week! Courtney won first place in the flash talk competition at the IBES Blue Sky event. She also won an IBES Graduate Student Research Training and Travel Award. These awards highlight he importance of Courtney's research on how defaunation impacts ecosystems in Kenya. Thanks to IBES for supporting our work and helping amplify our research -- and way to go Courtney!
As the fall semester gets into swing, the lab is having a lot of fun and making progress on research. Several milestones should not go unnoticed, and there are photos to boot. In no particular order:
Tyler was elected to the Ecological Society of America's 2018-2022 cohort of Early Career Fellows. The Society Announced the honor to recognize members who have advanced ecological knowledge and applications and show promise to make outstanding contributions to a wide range of fields served by ESA.
It is a tremendous honor to join such an inspiring group of scholars. Thanks to ESA for the leadership and inspiration that it provides to the diversity and generations of ecologists.
Several members of the lab are just back from an extremely productive field trip. Highlights include a DNA barcoding workshop at the National Museums of Kenya (led by Kartzinel and Gill, and Director Musili from the East African Herbarium), many pre-dawn captures of small mammals (led by Brown and collaborators from the Goheen lab), and many trees and and megaherbivores counted (led by Gill and Lokeny). Now the team is breaking in the new lab -- copious amounts of data to report soon! Photos of the highlights are below.
Howard Hughes Medical Institute (HHMI) just released a “BioInteractive” lab featuring our research on the diets of savanna herbivores.
Educators and students in high school and college biology courses will go on an expedition to Mpala Research Centre in Kenya, where they can investigate niche partitioning as a mechanism that enables similar species to coexist.
This extraordinarily engaging and informative BioInteractive module is inspired by — and uses real data from — our 2015 PNAS paper: “DNA metabarcoding illuminates dietary niche partitioning by African large herbivores.” The paper is becoming a “textbook” example of niche partitioning and DNA-based approaches in ecology.
Together with Rob Pringle and our collaborators, we hope this interactive will reach thousands of students worldwide.
The full text of this exciting new paper is online today: Feeding immunity: physiological and behavioral responses to infection and resource limitation. The article appears in a special feature of Frontiers in Immunology entitled Wild immunity -- the answers are out there. Congratulations to Sarah Budischak, Andrea Graham, and coauthors!
One of the most exciting aspects of this paper is the idea of "rewilding laboratory mice" to begin understanding the ecology of this model organism in genetics and medicine. What happens when lab mice are infected with an intestinal parasite, put outside, and tasked with surviving in a world with limited resources?
Add on top of that all of the exciting technology brought together to probe this creative experiment for mechanism -- PIT tags, DNA metabarcoding, NMR spectroscopy -- and you've got the makings of a classic. In this experiment, custom-built feeding devices capable of tracking foraging behavior, paired with DNA metabarcoding, revealed compensatory feeding behaviors by mice that otherwise might have masked the effects of infection.
Especially relevant to research in our lab, a hormone called leptin that serves as an indicator of hunger and body fat was correlated with consumption of different species of wild plants. Animals with higher leptin concentrations tended to eat more protein-rich clovers and other legumes than did animals with lower leptin, potentially pointing to different foraging behaviors and differential selectivity for wild foods as mechanisms for dealing with infection while reestablishing a dietary niche after generations in the laboratory. Although the effect sizes for the DNA metabarcoding data were small, these tantalizing trends highlight the importance of these measurements and the value of the technique. A valuable contribution.
