Isotopic evidence for residential mobility of farming communities during the transition to agriculture in Britain
(2016)
Development of agriculture is often assumed to be accompanied by a decline in residential mobility, and sedentism is frequently proposed to provide the basis for economic intensification, population growth and increasing ...
A highly infective plant-associated bacterium influences reproductive rates in pea aphids
(2016)
Pea aphids, A cyrthosiphon pisum, have the potential to increase reproduction as a defence against pathogens, though how frequently this occurs or how infection with live pathogens influences this response is not well ...
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 ...
The easternmigratory caribou
(2016)
Understanding the evolutionary history of contemporary animal groups is essential for conservation and management of endangered species like caribou (Rangifer tarandus). In central Canada, the ranges of two caribou subspecies ...
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 ...
Kinship as a frequency dependent strategy
(2016)
Humans divide themselves up into separate cultures, which is a unique and ubiquitous characteristic of our species. Kinship norms are one of the defining features of such societies. Here we show how norms of marital residence ...
Deceived by stripes
(2016)
Conspicuous coloration, which presumably makes prey more visible to predators, has intrigued researchers for long. Contrastingly coloured, conspicuous striped patterns are common among lizards and other animals, but their ...
Dopamine regulates termite soldier differentiation through trophallactic behaviours
(2016)
Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic ...
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 ...
