Flexible females: nutritional state influences biparental cooperation in a burying beetle [0.03%]
灵活的雌性：营养状态影响埋葬甲中的双亲合作行为
Georgia A Lambert,Per T Smiseth

In species that provide biparental care, there is a sexual conflict between parents over how much each should contribute toward caring for their joint offspring. Theoretical models for the resolution of this conflict through behavioral nego...
Parental overproduction allows siblicidal bird to adjust brood size to climate-driven prey variation [0.03%]
父母过度繁殖使同窝雏鸟相残的鸟类能够调整后代数量以适应气候驱动的食物资源变化

Parental overproduction is hypothesized to hedge against uncertainty over food availability and stochastic death of offspring and to improve brood fitness. Understanding the evolution of overproduction requires quantifying its benefits to p...
Sensory trap leads to reliable communication without a shift in nonsexual responses to the model cue [0.03%]
感官陷阱导致没有模型线索非性反应转变的可靠通信

Skye D Fissette et al.
The sensory trap model of signal evolution suggests that males manipulate females into mating using traits that mimic cues used in a nonsexual context. Despite much empirical support for sensory traps, little is known about how females evol...
A new trophic specialization buffers a top predator against climate-driven resource instability [0.03%]

Intraspecific phenotypic variability is key to respond to environmental changes and anomalies. However, documenting the emergence of behavioral diversification in natural populations has remained elusive due to the difficulty of observing s...
Population turnover, behavioral conservatism, and rates of cultural evolution [0.03%]
人口更迭，行为保守性和文化进化速率

Cultural evolution facilitates behavioral adaptation in many species. The pace of cultural evolution can be accelerated by population turnover, where newcomers (immigrants or juvenile recruits) introduce adaptive cultural traits into their ...
Effects of past mating behavior versus past ejaculation on male mate choice and male attractiveness [0.03%]
以往交配行为与以往射精经历对雄性择偶和雄性吸引力的影响

Meng-Han Joseph Chung et al.
Past reproductive effort allows males to assess their ability to acquire mates, but it also consumes resources that can reduce their future competitive ability. Few studies have examined how a male's reproductive history affects his subsequ...
Housework or vigilance? Bilbies alter their burrowing activity under threat of predation by feral cats [0.03%]
是做家务还是保持警惕？布宁鼠在被家猫捕猎时会改变打洞的行为

Behavioral adjustments to predation risk not only impose costs on prey species themselves but can also have cascading impacts on whole ecosystems. The greater bilby (Macrotis lagotis) is an important ecosystem engineer, modifying the physic...
Persistence associated with extractive foraging explains variation in innovation in Darwin's finches [0.03%]
与提取式采集相关的坚持解释了达尔文雀类在创新方面的差异

The capacity to create new behaviors is influenced by environmental factors such as foraging ecology, which can lead to phylogenetic variation in innovativeness. Alternatively, these differences may arise due to the selection of the underly...
Mutual mate guarding with limited sexual conflict in a sex-role-reversed shorebird [0.03%]
性别角色反转的滨鸟中的一种有限度的性冲突的相互配偶守卫行为
Johannes Krietsch,Mihai Valcu,Margherita Cragnolini et al.
Johannes Krietsch et al.
Mate guarding is typically considered a male strategy to protect paternity. However, under some circumstances, females might also benefit from guarding their mate. Female mate guarding might be particularly important in socially polyandrous...
Social networks reveal sex- and age-patterned social structure in Butler's gartersnakes (Thamnophis butleri) [0.03%]
社会网络揭示了巴特勒纹腹锦蛇(Thamnophis butleri)的社会结构的性别和年龄特征

Morgan Skinner et al.
Sex- and age-based social structures have been well documented in animals with visible aggregations. However, very little is known about the social structures of snakes. This is most likely because snakes are often considered non-social ani...
