Both costs and benefits determine the removal of Datura (Solanaceae) seeds by seed-dispersing ants [0.03%]
传粉蚂蚁传播曼陀罗属种子的获益与受损因素

Mutualisms confer both benefits and costs to participants, but costs have been largely ignored when considering how mutualisms function and evolve. Plants that are dispersed by ants produce seeds with attached nutrient-rich food rewards (el...
Landscape structure and species life history affect abundance-occupancy relationships [0.03%]
景观格局与物种生活史影响物种丰富度与生境占域率关系

More widespread species tend to be more locally abundant. This hypothesis has received support when considering single species abundance (mean density of individuals across sites) and occupancy (fraction of occupied sites) through time (int...
Unprecedented tropical cyclone in temperate-boreal ecotone drives declines in emergent conifers and canopy complexity [0.03%]
特热带气旋引发温带-北极过渡带地区高大常绿针叶林减少和冠层结构简化

Kirill Korznikov et al.
Poleward shifts in tropical cyclone (TC) activity have introduced unprecedented disturbances to Northeast Asia's boreal and temperate-boreal ecotone forests. As TCs migrate northward, they increasingly influence previously unaffected region...
Drivers of 30 years of ionomic change on a North American tallgrass prairie [0.03%]

Plant ionomes-the suite of chemical elements making up plant tissue-constrain plant performance and the nutrition of consumers. The possible mechanisms driving Nutrient Dilution-the globally distributed decline of essential element density ...
Forest owl community response following the removal of an intraguild invader [0.03%]
释放生态系统工程师后的森林鸟类群落变化响应研究——以中华鹰 Owl 侵入台湾赤腹鹰 Owl 栖地之案例探讨
J David Wiens,Damon B Lesmeister,Julianna M A Jenkins et al.
J David Wiens et al.
Invasive predators can reshape native predator assemblages, triggering cascading changes in broader wildlife communities. In western North America, the barred owl (Strix varia) is an invasive apex predator with well-documented negative impa...
Quantifying the success of prey crypsis, aposematism, and evasiveness in avoiding predator attack [0.03%]
量化猎物隐匿性、警戒色和机动力在避免捕食者攻击方面的成功程度
Daniel Linke,Jacqueline Hernandez Mejia,Valery N P Eche Navarro et al.
Daniel Linke et al.
Antipredator defenses typically act at distinct stages of the predation sequence-encounter, identification, approach, and subjugation. However, their effectiveness has rarely been quantified and compared simultaneously in wild predator-prey...
Recent warming produced consistent shifts in seasonal richness of actively flowering species across multiple ecosystems [0.03%]
近期升温导致多个生态系统中开花物种季相丰富度发生一致的变化
Isaac W Park,Tadeo H Ramirez-Parada,Sydne Record et al.
Isaac W Park et al.
Many plant species alter both the timing and duration of their flowering in response to changing climate and often differ with respect to the magnitudes or directions of their phenological responses to climate changes. These shifts may have...
Structuring the skies: Diel dynamics of migratory animal movement in the lower atmosphere [0.03%]
结构化天空：地气层中迁徙动物昼夜动态分布及其与环境因素的关系
Silvia Giuntini,Carolyn S Burt,Annika L Abbott et al.
Silvia Giuntini et al.
Earth's lower atmosphere is a vital ecological habitat, home to trillions of organisms that live, forage, and migrate through this medium. Despite its importance, this space is seldom considered a primary habitat for ecological or conservat...
An experimental test on the effects of dispersal from different habitat sources on community structure [0.03%]
不同生境来源的传播对群落结构影响的实验研究

Gustavo L Villarreal et al.
Biological interactions, disturbances, and demographic stochasticity often drive population declines and local extinctions. Dispersal can counterbalance these drivers by rescuing small populations or facilitating recolonization. Using fresh...
The spatial scale of adaptation in pond-breeding amphibian larvae [0.03%]
适应pond-breeding两栖动物幼体的空间尺度

Mark C Urban
The spatial scale of adaptation is fundamental to our understanding of evolutionary ecology. Traditionally, strong gene flow and weak selection were expected to prevent adaptive evolution at finer spatial scales, but instances of microgeogr...
