The choices of when, where, and with whom to mate represent some of the most important decisions an individual can make to increase their fitness. Several studies have shown that the resources available to an individual during development c...

Deciding where to eat and raise offspring carries important fitness consequences for all animals, especially if foraging, feeding, and reproduction increase pathogen exposure. In insects with complete metamorphosis, foraging mainly occurs d...
Effects of load-lightening and delayed extrapair benefits on the fitness consequences of helping behavior [0.03%]
减轻负载和延时额外配对利益对助人行为适应价值的影响

In most cooperative breeders, helping is directed at close kin, allowing helpers to gain indirect fitness benefits by increasing the reproductive success of close relatives, usually their parents. Extrapair paternity (EPP) occurs at high ra...
Experimental cross-fostering of eggs reveals effects of territory quality on reproductive allocation [0.03%]

Parental and territory quality are often correlated in territorial birds, and both factors influence the resources allocated to offspring. Surprisingly, the relative contribution of these two components of variation in parental investment r...
Genomic analysis of MHC-based mate choice in the monogamous California mouse [0.03%]

Variation at Major Histocompatibility Complex (MHC) genes is thought to be an important mechanism underlying mate choice in vertebrates, with individuals typically predicted to prefer MHC-dissimilar reproductive partners. However, analyses ...
Organization enhances collective vigilance in the hovering guards of Tetragonisca angustula bees [0.03%]

One benefit of group living is vigilance against predators. Previous studies have investigated the group size effect, where individual vigilance decreases as group size increases without reducing the overall ability of the group to detect p...

In many prey taxa with aposematic coloration, prey defenses also involve signals in other modalities (odors, sounds, etc.), yet the selective forces that have driven multimodality in warning displays are not well understood. One potential h...
Social interactions predict genetic diversification: an experimental manipulation in shorebirds [0.03%]
社会交往预测基因分化：滨鸟的实验操作

Charles Cunningham et al.
Mating strategy and social behavior influence gene flow and hence affect levels of genetic differentiation and potentially speciation. Previous genetic analyses of closely related plovers Charadrius spp. found strikingly different populatio...

Why are some individuals more prone to gamble than others? Animals often show preferences between 2 foraging options with the same mean reward but different degrees of variability in the reward, and such risk preferences vary between indivi...
