Multispecies Coexistence Emerges From Pairwise Exclusions in Communities With Competitive Hierarchy [0.03%]
竞争存在等级的多物种群落中成对相互作用排除导致多种类共存

Competitive coexistence is often understood as an additive process where coexisting species pairs, triplets, etc. combine to form larger communities. However, emergent coexistence-where multispecies persistence occurs without pairwise coexi...
Delicate Trade-Offs: Nonlinear Multiple Biotic Constraints on Absorptive Fine Root Lifespan Across Trees [0.03%]
精细的权衡关系：树木吸收型细根寿命的多重生物约束及其非线性效应

Root lifespan is crucial for predicting carbon and nutrient cycling. While economic theories suggest root construction cost primarily determines root lifespan, the role of extrinsic biotic factors remains unexplored. We analysed 61,221 imag...
Synthesis of Nature's Extravaganza: An Augmented Meta-Meta-Analysis on (Putative) Sexual Signals [0.03%]

Colourful body parts and bizarre displays that do not seem to contribute to the survival of individuals that express them have puzzled biologists for centuries. Sexual selection theory posits that these traits evolved because more conspicuo...
Linking Individual Performance to Density-Dependent Population Dynamics to Understand Temperature-Mediated Genotype Coexistence [0.03%]
联系个体表现型与密度依赖性种群动态以理解温度介导的基因型共存关系
Marjolein Bruijning,Luc De Meester,Marco D Visser et al.
Marjolein Bruijning et al.
The persistence of local populations exposed to climate change depends on their adaptive potential and on the ability of local individuals to compete with migrating conspecifics tracking environmental shifts. Modern coexistence theory (MCT)...
Biodiversity modulates the cross-community scaling relationship in changing environments [0.03%]
生物多样性调制变化环境中的跨群落规模关系

Vojsava Gjoni et al.
Organismal abundance tends to decline with increasing body size. Metabolic theory links this size structure with energy use and productivity, postulating a size-abundance slope of -0.75 that is invariant across environments. We tested the r...
Urbanisation Facilitates Intrapopulation Dietary Niche Diversity in a Generalist Carnivore [0.03%]
城市化促进了广食性肉食动物种群内部饮食生态位多样性
Tal Caspi,Emily Sit,Monica G Serrano et al.
Tal Caspi et al.
The niche variation hypothesis predicts that members of generalist species are specialists, and that the degree of individual specialisation correlates positively with resource diversity. Urban landscapes are highly heterogeneous in resourc...
Urbanisation Drives the Decoupling, Simplification, and Homogenization of Aquatic and Terrestrial Food Webs [0.03%]
城市化驱动水生和陆地食物网的脱钩、简化和同质化
Kilian Perrelet,Lauren M Cook,Merin Reji Chacko et al.
Kilian Perrelet et al.
Aquatic and terrestrial communities often co-occur at close distances, enabling biotic interactions across ecosystem boundaries. While such interactions in natural habitats contribute to complex, coupled food webs, their dynamics in enginee...
Legacy of the Lost and Pressure of the Present: Malagasy Plant Seeds Retain Megafauna Dispersal Signatures but Downsize Under Human Pressure [0.03%]
消失巨兽的遗产与人类活动的压力：马达加斯加植物种子保留了巨型动物传播的特征，但其尺寸在人类压力下减小

Ongoing declines of large-bodied frugivores limit the dispersal of large-seeded plants, contributing to their (local) demise and 'downsizing' of seeds across assemblages. However, the extent to which human pressure leads to contemporary see...
Migratory Strategy is a Key Factor Driving Interactions at Wind Energy Facilities in At-Risk North American Bats [0.03%]
迁徙策略是驱动濒危北美蝙蝠在风能设施中相互作用的关键因素
Caitlin J Campbell,David M Nelson,Juliet Nagel et al.
Caitlin J Campbell et al.
Animal migration remains poorly understood for many organisms, impeding understanding of movement dynamics and limiting conservation actions. We develop a framework that scales from movements of individuals to the dynamics of continental mi...
Mycorrhizal Network and Symbiotic N-Fixer Jointly Enhance the Interplant Nitrogen Sharing [0.03%]
菌根网络和共生固氮菌共同促进植物间氮共享
Yuxuan Gao,Yuntao Wu,Pengfei Chang et al.
Yuxuan Gao et al.
Symbioses with mycorrhizal fungi and nitrogen-fixing bacteria (NFB) enhance nitrogen (N) acquisition in host plants and may promote N transfer to neighbouring plants through mycorrhizal networks (MN). Nevertheless, the extent and mechanisms...
