Maternal care in crayfish has been extensively studied, but little is known of its response to environmental factors. We studied the duration of maternal care and its association with the juvenile development of marbled crayfish Procambarus...
Male juvenile golden snub-nosed monkeys acting as the mountee to receive grooming in their same-sex mounts [0.03%]
雄性幼年金丝猴作为骑副接受同性骑跨中的梳理行为
Pengzhen Huang,Julie A Teichroeb,Endi Zhang et al.
Pengzhen Huang et al.
Same-sex mounts provide male juvenile golden snub-nosed monkeys (Rhinopithecus roxellana) with opportunities to practice heterosexual copulatory skills and are often followed by grooming (post-mounting grooming, PMG). We hypothesized that j...
Rain-harvesting behavior in free-ranging prairie rattlesnakes (Crotalus viridis) [0.03%]

Organisms inhabiting arid environments face challenges to obtain dietary water. To prevent desiccation, some organisms possess unique adaptations to harvest water from infrequent and unpredictable rainfall, including several squamates (snak...
The influence of the post-autotomy regeneration of a sexual trait and mating tactics in a fiddler crab [0.03%]
断肢后再长对雄性招潮蟹的一个性征及交配战术的影响
Pablo D Ribeiro,Nahuel E Farías,Emiliano H Ocampo et al.
Pablo D Ribeiro et al.
Male fiddler crabs own an enlarged claw which is a weapon and an ornament. The enlargement of this claw begins from the juvenile stage and continues throughout life. Males may voluntarily lose (i.e., autotomize) this claw. After several mol...
Sexually differentiated decision-making involves faster recruitment in the early stages for the Tibetan antelopes Pantholops hodgsonii [0.03%]
藏羚羊(Pantholops hodgsonii)性二型决策涉及早期更快的募集速率
Qin Zhu,Jian Guan,Tianya Lei et al.
Qin Zhu et al.
Group living is widespread across diverse taxa, and the mechanisms underlying collective decision-making in contexts of variable role division are critical for understanding the dynamics of group stability. While studies on collective behav...
Evolutionary factors and habitat filtering affect the pattern of Gerbillinae diversity [0.03%]
进化因素和生态位过滤影响鼠兔类多样性分布模式
Yaqian Cui,Jilong Cheng,Zhixin Wen et al.
Yaqian Cui et al.
How ecological and evolutionary factors affect small mammal diversity in arid regions remains largely unknown. Here, we combined the largest phylogeny and occurrence dataset of Gerbillinae desert rodents to explore the underlying factors sh...

Daniel T Blumstein et al.
The nonlinearity and fear hypothesis predicts that highly aroused vocal mammals and birds produce vocalizations (notably alarm calls and screams) which contain a variety of nonlinear phenomena (NLP). Such vocalizations often sound "noisy" b...
Taxonomic, phylogenetic, and functional nestedness of mammal assemblages in the Zhoushan Archipelago, China [0.03%]
中国舟山群岛哺乳动物类群、系统发育和功能的嵌套性
Chengxiu Zhan,Bicheng Li,Chuanwu Chen et al.
Chengxiu Zhan et al.
Nestedness is an important part of the theoretical framework of island biogeography and community ecology. However, most previous studies focused on taxonomic dimension and overlooked functional and phylogenetic nestedness. Here, we simulta...
Intra-tooth stable isotope analysis reveals seasonal dietary variability and niche partitioning among bushpigs/red river hogs and warthogs [0.03%]
门齿稳定同位素分析揭示了灌丛猪/红河猪和疣猪的季节性饮食变异性和生态位分化
Deming Yang,Kevin T Uno,Thure E Cerling et al.
Deming Yang et al.
How animals respond to seasonal resource availability has profound implications for their dietary flexibility and realized ecological niches. We sought to understand seasonal dietary niche partitioning in extant African suids using intra-to...
Immune stress and diet influence reproductive fitness in male tuatara (Sphenodon punctatus) [0.03%]
免疫压力和饮食影响男性tuatara(Sphenodon punctatus)的生殖fitness
