Regional landscape differences lead to contrasts in the strength of environmental sorting among crustacean zooplankton metacommunities

Oikos, EarlyView.
Processes underlying metacommunity structuring are important for understanding species tracking of environmental change at a landscape scale. Species' functional traits more closely reflect their ecological roles than taxonomy, therefore, adopting a functional approach allows us a better understanding of metacommunity structuring.

Plasticity and overlap of trophic niches in tropical breeding Laridae

Marine Ecology Progress Series
Trophic ecology of seabirds in tropical regions remains poorly understood despite the large number of multispecies breeding colonies supported by these ecosystems. Here, we used the isotopic niche (δ15N and δ13C) of 5 Laridae species at 2 breeding areas in Cuba to analyze the plasticity and interspecific overlap of trophic niche determined from chick ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

Land use extent and intensity affect the trophic structure of apex fish in neotropical lagoons

Water Biology and Security
The conversion of natural ecosystems to human land use is a primary cause of worldwide biodiversity loss and trophic structure changes in ecosystems. We investigated the effect of human land use at different spatial extents and aquatic trophic state on ...

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

The Influence of Habitat Heterogeneity and Human Disturbance on Trophic Interactions of Sebastiscus marmoratus and Scorpaenopsis cirrosa in Wanshan Archipelago

Ecology and Evolution
Habitat heterogeneity and human disturbances drive variations in interspecific interactions among fish species. Trophic niche analysis is a crucial approach for understanding these interactions.

Greater future range expansions in alien than native ant species

Oikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.
