Abstract:
... Human‐induced global changes such as nitrogen (N) deposition, climatic warming and rainfall changes have been determined to be common drivers of current plant community dynamics. However, it is unclear if and how the individual and combined effects of these drivers differently influence plant diversity and its relationship with productivity at the global scale. Here, we performed meta‐analyses wit ...

Abstract:
... Climate change is most pronounced at high latitudes, where plant and animal populations are often strongly influenced by environmental fluctuations related to climate and weather. Environmental conditions can co‐fluctuate over large distances and thereby synchronise primary production in space. However, large‐scale studies of such spatiotemporal patterns remain rare in the Arctic, where short time ...

Abstract:
... Changes in the number of generations per year (voltinism) have been among the most common phenological responses to climate warming in insects inhabiting seasonal environments. Nevertheless, numerous species have maintained univoltine (one generation per year) phenology with increasing temperatures, indicating the involvement of phylogenetic, ecological or some other constraints on phenological ch ...

Subject:
Coleoptera; bark beetles; behavior; biosynthesis; conifers; ecosystems; forests; gardens; herbivores; landscapes; models; monoterpenoids; phloem; phylogeny; population; trees; variability
Abstract:
... Plants resist herbivores using both constitutive and induced defenses. Limited resources and biosynthesis costs of anti‐herbivore compounds may impose tradeoffs between these modalities, but the evidence is conflicting. We postulated that biological and ecological scale may influence potential tradeoffs and analyzed constitutive‐induced relationships from genotypic to interspecific levels. We focu ...

Subject:
density; immigration; interspecific variation; knowledge; landscapes; simulation models; species richness
Abstract:
... Conspecific negative density dependence (CNDD) has been highlighted as a main driver of biodiversity maintenance. However, while there is general consensus on the scale‐dependent and interacting nature of ecological processes, there is limited knowledge about the relative importance of CNDD across spatial scales and on its interaction with other processes, such as dispersal and immigration. While ...

Abstract:
... Plastic and evolutionary changes in traits related to biotic interactions are crucial for the local persistence of populations under global warming. Yet, how acute and developmental thermal plasticity evolve and shape predation rates has been poorly studied, especially in the context of latitude‐driven thermal evolution. A powerful predictive framework is given by the climatic variability hypothes ...

Abstract:
... Environmental temperatures influence ectotherms’ physiology and capacity to perform activities necessary for survival and reproduction. Time available to perform those activities is determined by thermal tolerances and environmental temperatures. Estimates of activity time might enhance our ability to predict suitable areas for species’ persistence in face of climate warming, compared to the exclu ...

Abstract:
... Body size is a key selected trait in many animal systems: larger size is sexually selected for in males because it confers a reproductive advantage during contest competition for access to females, and larger females are naturally selected for fecundity. Herein, we used radio‐telemetry to gather a large dataset of male–female interactions and DNA paternity analyses to characterize the intensity of ...

Abstract:
... Individual hosts vary substantially in their parasite loads. However, whether individual hosts have consistently different loads remains uncertain. If so, hosts that have consistently high parasite loads may serve as key reservoirs or super‐spreaders. Thus, identifying whether individuals persistently differ in their parasitism and the factors that explain these patterns constitute important issue ...

Abstract:
... Higher temperatures as a consequence of global climate change may considerably alter trophic interactions. Ectothermic herbivores and carnivores generally ingest more food with rising temperature as their metabolic rates increase with rising temperature. However, omnivorous ectotherms may respond in two ways: quantitatively by consuming more food and qualitatively by altering their degree of herbi ...

Abstract:
... Airborne dispersal is a key part of the life history of many saprotrophic fungi. Theory suggests a transition from growth and resource capture to airborne dispersal at some point as the resource availability in a patch declines, but in the absence of an experimental model system this theory has not been empirically tested. For saprobes, resources are arrayed in an ever‐shifting archipelago of isla ...

Subject:
dimensions; dynamics; ecological communities; ecological competition; empirical research; microhabitats; models; niches
Abstract:
... Negative and positive ecological interactions have opposite effects on the structure of ecological communities, in particular in terms of ecological similarity among interacting species. In nature, species belonging to the same guild often interact in both negative and positive ways, yet the interplay between interactions of different kinds in intraguild community dynamics remains poorly understoo ...

Abstract:
... The tight association between yeast metabolites and the attraction of fly species provides key evolutionary innovations that generate immense diversity within the genus Drosophila. Why and how changes in Drosophila niche preferences occur, and what role yeasts play in species specialization, is still largely unknown. Here, we analyze adult preference and larval development across three species of ...
