Predation risk is associated with head-size-related divergence in breeding phenology in a female sea duck [0.03%]
捕食风险与一种雌性海鸭的繁殖习性和头部大小相关的分化有关

Bertille Mohring et al.
Breeding phenological responses to changing environments affect demographics and population persistence. However, inter-individual variation in adjustment of reproductive timing to predation risk has been overlooked. We thus tested whether ...

Effective conservation of the iconic old forest lichen Lobaria pulmonaria depends on understanding its life history bottlenecks. To address this, reproductive dynamics were evaluated in 302 juvenile and early-reproducing thalli transplanted...
Plant invasion reduces density-dependent pollination but not florivory [0.03%]
植物入侵降低了密度依赖性传粉但并未影响食花率

Understanding the impact of plant invasion on multitrophic community dynamics and coexistence requires widespread and frequent monitoring. Deep learning can be used to automate the measurement of indicators of ecological interactions and ec...
Quantitative fatty acid signature analysis (QFASA) to explore the diet of the plateau pika (Ochotona curzoniae) during winter on the Qinghai-Xizang (Tibetan) plateau [0.03%]
青藏高原冬季高亚洲鼠兔(Ochotona curzoniae)食性的定量脂肪酸标志分析(QFASA)研究
Min Li,Zengguang Jin,Lukasz Oldakowski et al.
Min Li et al.
The plateau pika, a keystone species of the Tibetan Plateau, is also widely poisoned as an agricultural pest. An intriguing observation is that pika are more abundant where their main competitor (domestic yak) is also most abundant. A recen...
Leaf status drives shifts in both community composition and trophic mode of foliar endophytic fungi via variation in functional traits in Tibetan alpine meadow [0.03%]
叶片状态通过功能特征的变化驱动西藏高寒草甸内生真菌群落组成和营养模式的转变

Foliar endophytic fungi (FEF) influence plant performance and early litter decay, yet whether leaf senescence imposes common assembly rules across hosts remains unclear. Here, we collected paired live and senescent leaves from 11 plant spec...
Fertilization and herbivore exclusion promote more deterministic processes in plant community assembly on the Qinghai-Tibet Plateau [0.03%]
施肥和食草动物排除促进青藏高原植物群落组装的决定性过程
Wei Zhao,Shaohao Bang,Zhenzhen Pan et al.
Wei Zhao et al.
Fertilization and herbivore exclusion are two key forces influencing community structure and species richness in grassland ecosystems. However, the extent to which these factors influence the relative contributions of deterministic and stoc...
Effects of population density on life history traits in a moth: in search of proximate and ultimate explanations [0.03%]
密度对一种蛾的生活史特征的影响：寻找直接原因和根本原因
Kerli Kuusk,Toomas Esperk,Tiit Teder et al.
Kerli Kuusk et al.
Population density often modifies the phenotypes of the members of the population. Such density-dependent phenotypic plasticity can affect basic life history traits of the organisms. In insects, a frequently observed expression of such plas...
Parallel elevational replacement of hosts and parasites in a highly susceptible songbird genus [0.03%]
一种高度易感鸣鸟属中宿主和寄生虫的平行海拔替代现象
Daniele L F Wiley,Jessie L Williamson,Silas E Fischer et al.
Daniele L F Wiley et al.
Elevational replacement distribution patterns underpin montane diversity and reflect the interaction of both biotic and abiotic pressures, but the degree to which parasites exhibit elevational zonation remains unclear. Investigating infecti...
Behavioural responses to heat in an arid-zone bird vary with thermal, hygric and social factors [0.03%]
热、湿和社会因素影响下荒漠带鸟类的热应激行为反应机制研究
J R D Whyte,A E McKechnie,J K Crossley et al.
J R D Whyte et al.
The severity of fitness costs resulting from behavioural trade-offs between heat dissipation and activities such as foraging is increasing with advancing climate change. In terrestrial habitats, shade and water may buffer individuals from t...
Multiscale effects of habitat fragmentation on plant functional composition: insights from Thousand Island Lake, China [0.03%]
千岛湖植物功能谱尺度分割效应研究

Guang Hu et al.
Understanding the multi-scale effects of habitat fragmentation on biodiversity is essential for effective conservation in a rapidly changing world. Here, we assessed plant functional composition in edge and interior plots across 28 islands ...
