Trade-offs across life history stages and social association types shape winter communal roosting in a long-lived raptor [0.03%]
生活史各阶段的权衡和社会联系类型塑造了长寿命猛禽的冬季群栖行为

Benedetta Catitti et al.
Social interactions among conspecifics can have significant fitness implications, but how social behaviours develop in wild animals remains poorly understood. Here, we examine the intrinsic drivers of a social behaviour, communal winter roo...
Early life exploration behaviour and life-history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon [0.03%]
大西洋鲑鱼生命早期探索行为和生活史位点在适应性基因组热点中共定位

The traits that are important for adaptation may exhibit genetic correlation due to pleiotropy or as a result of linkage. Understanding the genetic architecture of such correlations is important for predicting the selection response of popu...
Fitness consequences of parasitism in a changing world: A case study with bird blow flies and sagebrush songbirds [0.03%]
寄生在变化中的世界里的适应后果——以飞鸟蝇和亚瑟布鲁姆歌bird为例的研究

Host-parasite interactions increasingly are influenced by human-induced rapid environmental change (HIREC), and the fitness effects of parasitism may be compounded or exacerbated by host traits and/or exposure to additional extrinsic stress...
Changing food availability and its effect on the heritability of offspring size in woodland passerine birds [0.03%]
食物供给变化及其对林中鸣鸟后代体型遗传率的影响
Emma Vatka,Markku Orell,Seppo Rytkönen et al.
Emma Vatka et al.
Climate warming has been associated with widespread body size declines in many vertebrate taxa, but relatively little is known about possible climate warming induced shifts in trait heritabilities. The main goal of the study was to investig...
Behavioural tactics across thermal gradients align with partial morphological divergence in brook charr [0.03%]
温度梯度下的行为策略与溪红点鲑的部分形态分化一致

Aliénor Stahl et al.
Understanding how animals balance environmental constraints is essential for predicting species persistence under climate change. In thermally stratified lakes, cold water fishes such as brook charr (Salvelinus fontinalis) must navigate ver...
Belowground effects of ground-dwelling large herbivores in forest ecosystems [0.03%]
大型栖地 Herbivore 对森林生态系统土壤的影响

Letícia Gonçalves Ribeiro et al.
Large terrestrial mammalian herbivores (LMHs) play a critical role in ecosystems, but the effects of these species on belowground zoogeochemistry in forest ecosystems remain poorly understood. This study aimed to investigate the influence o...
The pace of life along the river continuum: Hierarchical variation in salmonid life-history diversity [0.03%]
河流生态系统中鲑鱼生活史多样性的等级差异及其对生境连续性的响应

Diversity in life-history strategies is a key aspect of population resilience. However, the spatial and environmental factors that drive this variation remain poorly understood. In a recent study, Shida and Sato combined year-round surveys ...
Migratory connectivity and barrier-crossing flights of Vermivora warblers are associated with synoptic weather conditions [0.03%]
迁移连通性及Vermivora林莺属鸟类迁徙过程中的越障飞行与天气状况有关
Gunnar R Kramer,David E Andersen,David A Buehler et al.
Gunnar R Kramer et al.
Migratory birds often navigate inhospitable barriers (e.g. oceans, deserts) during migration. Barrier crossings are frequently associated with increased rates of mortality and likely impose selective pressures on migratory species that shap...

Understanding how sympatric predators coexist remains a central question in community ecology, particularly when those species are phylogenetically related obligate carnivores with similar body sizes and trophic roles. In the neotropics thi...
