Recognition of brood parasitic cuckoo nestlings poses a challenge to hosts because cues expressed by cuckoos and host young may be very similar. In theory, hosts should use flexible recognition rules that maximize the likelihood of rejecting cuckoo nestlings while minimizing the risk of...

Co-management between local communities and government agencies is promoted as a strategy to improve fisheries management. This paper considers the potential for co-management of sea turtle fisheries within four UK Overseas Territories (OTs) in the Caribbean, and for co-ordinated management...

The black throat patch or bib of male house sparrows, Passer domesticus, is often referred to as a "badge of status" or a "badge" because previous studies have shown bib size to be correlated with the social status of males. Yet, little is known about how strong and robust this relationship is...

In animal societies, kin selection is a critical evolutionary process, with cooperation evolving principally among relatives living in kin-structured populations. Theoretical and empirical studies have largely focused on population viscosity--the timing or distance of dispersal--as the key...

Helpers in cooperatively breeding species may gain direct fitness benefits that increase their survival probability and/or reproductive success. However, survival and productivity may be influenced by many other factors, including variation in dispersal, nepotistic interactions, or individual...
