Polygyny without wealth
(The Royal Society, 2015)
The occurrence of polygynous marriage in hunter–gatherer societies, which do not accumulate wealth, remains largely unexplored since resource availability is dependent on male hunting capacity and limited by the lack of ...
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 ...
Oviposition preference of cabbage white butterflies in the framework of costs and benefits of interspecific herbivore associations
(2015)
When deciding where to oviposit, herbivorous insects consider: (i) the plant’s value as a food source, (ii) the risks of competing with con- and heterospecific herbivores, and (iii) the risks of parasitism and predation ...
Crypsis via leg clustering
(2015)
The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species. Here, we studied this deceptive strategy by ...
A pheromone outweighs temperature in influencing migration of sea lamprey
(2015)
Organisms continuously acquire and process information from surrounding cues. While some cues complement one another in delivering more reliable information, others may provide conflicting information. How organisms extract ...
Sex ratio effects on reproductive strategies in humans
(2015)
Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex ...
New evidence on the tool assisted hunting exhibited by chimpanzees
(2015)
For anthropologists, meat eating by primates like chimpanzees (Pan troglodytes) warrants examination given the emphasis on hunting in human evolutionary history. As referential models, apes provide insight into the evolution ...
Social dominance modulates eavesdropping in zebrafish
(The Royal Society, 2015)
Group living animals may eavesdrop on signalling interactions between conspecifics and integrate it with their own past social experience in order to optimize the use of relevant information from others. However, little ...
Can differential nutrient extraction explain property variations in a predatory trap?
(2015)
Predators exhibit flexible foraging to facilitate taking prey that offer important nutrients. Because trap-building predators have limited control over the prey they encounter, differential nutrient extraction and trap ...
City lifemakes females fussy: sex differences in habitat use of temperate bats in urban areas
(The Royal Society, 2014)
Urbanization is a major driver of the global loss of biodiversity to mitigate its adverse effects, it is essential to understand what drives species’ patterns of habitat use within the urban matrix. While many animal species ...
