Body size predicts prey preference but not diet breadth in pythons

J. M. Barends, H. Naik

Journal of Zoology > 321 > 1 > 50 - 58

For gape‐limited predators like snakes that swallow their prey whole, large‐bodied species with wide gapes should theoretically be able to consume a more diverse range of prey than smaller species with narrow gapes and, therefore, may have broader diets. However, in cases where large‐bodied species exclude small prey, their diets may not necessarily be more taxonomically diverse compared to smaller...

Deciphering the Innate Lymphoid Cell Transcriptional Program

Cyril Seillet, Lisa A. Mielke, Daniela B. Amann-Zalcenstein, Shian Su, more

Cell Reports > 2016 > 17 > 2 > 436-447

Innate lymphoid cells (ILCs) are enriched at mucosal surfaces, where they provide immune surveillance. All ILC subsets develop from a common progenitor that gives rise to pre-committed progenitors for each of the ILC lineages. Currently, the temporal control of gene expression that guides the emergence of these progenitors is poorly understood. We used global transcriptional mapping to analyze gene...
