Discrete but variable structure of animal societies leads to the false perception of a social continuum
(2016)
Animal societies are typically divided into those in which reproduction within a group is monopolized by a single female versus those in which it is shared among multiple females. It remains controversial, however, whether ...
Coexistence of three sympatric cormorants
(2016)
Resource partitioning is well known along food and habitat for reducing competition among sympatric species, yet a study on temporal partitioning as a viable basis for reducing resource competition is not empirically ...
High atmospheric temperatures and ‘ambient incubation’ drive embryonic development and lead to earlier hatching in a passerine bird
(The Royal Society, 2016)
Tropical and subtropical species typically experience relatively high atmospheric temperatures during reproduction, and are subject to climate-related challenges that are largely unexplored, relative to more extensive work ...
Attack risk for butterflies changes with eyespot number and size
(2016)
Butterfly eyespots are known to function in predator deflection and predator intimidation, but it is still unclear what factors cause eyespots to serve one function over the other. Both functions have been demonstrated in ...
Trophic niche divergence among colour morphs that exhibit alternative mating tactics
(2016)
Discrete colour morphs associated with alternative mating tactics are assumed to be ecologically equivalent. Yet suites of behaviours linked with reproduction can also favour habitat segregation and exploitation of different ...
Parents face quantity quality trade offs between reproduction and investment in offspring in Iceland
(2016)
How to optimally allocate time, energy and investment in an effort to maximize one’s reproductive success is a fundamental problem faced by all organisms. This effort is complicated when the production of each additional ...
Mix it and fix it
(2016)
Animals communicating via scent often deposit composite signals that incorporate odorants from multiple sources however, the function of mixing chemical signals remains understudied. We tested both a ‘multiple-messages’ ...
Social familiarity affects Comparative phylogenetic analyses uncover the ancient roots of Indo European folktales
(2016)
Ancient population expansions and dispersals often leave enduring signatures in the cultural traditions of their descendants, as well as in their genes and languages. The international folktale record has long been regarded ...
Do grandparents compete with or support their grandchildren?
(2016)
Previous research has found that the presence of grandparents, particularly grandmothers, is often positively associated with child survival. Little research has explored the potential mechanisms driving these associations. ...
A scenario for the evolution of selective egg coloration
(2016)
Behavioural plasticity can drive the evolution of new traits in animals. In oviparous species, plasticity in oviposition behaviour could promote the evolution of new egg traits by exposing them to different selective ...
