Social relationships among animals emerge from interactions in multiple ecological and social situations. However, we seldom ask how each situation contributes to the global structure of a population, and whether different situations contribute different information about social relationships and the position of individuals within the social fabric. Griffon vultures () interact socially in multiple situations, including communal roosting, joint flights, and co-feeding.

Clinical research output in the emergency department (ED) continues to be constrained by limitations in funding for researchers, demands of patient care on ED providers, and difficulties in obtaining high-quality data. In response, several institutions have established programs in which student volunteers are integrated into department workflows to increase clinical research output and introduce pre-health students to careers in medicine. One such program, the student volunteer clinical research program, presently consists of over 40 undergraduate and post-baccalaureate student volunteers who screen, consent, and enroll patients into prospective studies in the ED of the University of California, Los Angeles (UCLA) Ronald Reagan Medical Center.

Effective communication requires a match among signal characteristics, environmental conditions, and receptor tuning and decoding. The degree of matching, however, can vary, among others due to different selective pressures affecting the communication components. For evolutionary novelties, strong selective pressures are likely to act upon the signal and receptor to promote a tight match among them.
