TL;DR: The broad geographic patterns are consistent with a hypothesis of widespread changes in climate on wintering, migratory, or breeding areas that in turn may differentially affect populations of aerial insects, but other explanations are possible.
Journal ArticleDOI
Trophic partitioning in tropical rain forest birds: insights from stable isotope analysis.
L. Gerardo Herrera,Keith A. Hobson,Keith A. Hobson,Malinalli Rodríguez,Patricia Balderas Hernández +4 more
TL;DR: The authors' analyses provided insights into the nutritional contribution of plant and animal sources of protein and distinguish their photosynthetic origin over relatively long average time periods.
Journal ArticleDOI
Lizards combine stored energy and recently acquired nutrients flexibly to fuel reproduction
TL;DR: The results suggest that the energy allocation strategy used for reproduction differs among egg components, and that the use of recently acquired energy for reproduction may be more widespread in ectotherms than thought previously.
Journal ArticleDOI
Isotopic evidence that dragonflies (Pantala flavescens) migrating through the Maldives come from the northern Indian subcontinent.
TL;DR: In this article, the authors used stable isotope analysis to track dragonfly wing chitin δ2H values in 49 individual Pantala flavescens from the November-December migration through the Maldives.
Journal ArticleDOI
Changes in food web structure alter trends of mercury uptake at two seabird colonies in the Canadian Arctic.
TL;DR: How a shift in diet of an Arctic seabird resulted in a change of trophic position and how that change affected exposure to mercury over time is examined.
