Residence Time Structures Microbial Communities Through Niche Partitioning

Ecology Letters
ABSTRACT Much of life on Earth is at the mercy of currents and flow. Residence time ( τ ) estimates how long organisms and resources remain in a system based on the ratio of volume ( V ) to flow rate ( Q

Limited spatiotemporal niche partitioning among mesocarnivores in Gorongosa National Park, Mozambique

Ecology and Evolution
Competition drives community composition and structure in many ecosystems. Spatial and temporal niche partitioning, in which competing species divide the environment in space or time, are mechanisms that may allow for coexistence among ecologically ...

Partial Niche Partitioning in Three Sympatric Gull Species Through Foraging Areas and Habitat Selection

Ecology and Evolution
Anthropogenic habitat change is having a detrimental impact on biodiversity worldwide, altering the foraging behaviour and population dynamics of many species.

Carnivore Niche Partitioning in a Human Landscape

The American Naturalist, 2022
AbstractTo minimize competitive overlap, carnivores modify one of their critical niche axes: space, time, or resources. However, we currently lack rules for how carnivore communities operate in human-dominated landscapes. We simultaneously quantified overlap in the critical niche axes of a simple carnivore community-an apex carnivore (Puma concolor), a

Niche partitioning in congeneric scorpions

Invertebrate Biology, 2020
AbstractSpecies in the scorpion genus Centruroides (Scorpiones: Buthidae) are good candidates for the study of ecological niche partitioning because of their habitat plasticity, widespread geographic distribution, and presence of cryptic species. Currently, three species belonging to three subgroups of Centruroides are distributed along the Isthmus of ...

An allometric prior enhances acoustic niche partitioning signal

Journal of the Royal Society Interface, 2022
Abstract The acoustic niche hypothesis suggests that vocal signals of sympatric animal species are structured so as to minimize acoustic interference and facilitate communication. Accordingly, each species attempts to establish its own acoustic bandwidth so that intra-species signals are not masked. Detecting a non-random partitioning

Niche partitioning of closely related symbiotic dinoflagellates

Molecular Ecology, 2007
AbstractReef‐building corals are fundamental to the most diverse marine ecosystems, yet a detailed understanding of the processes involved in the establishment, persistence and ecology of the coral–dinoflagellate association remains largely unknown. This study explores symbiont diversity in relation to habitat by employing a broad‐scale sampling regime

Spatial and temporal niche partitioning in grassland ants

Oecologia, 2001
Species coexistence can reflect niche partitioning at several spatial and temporal scales. We measured patterns of spatial and temporal niche overlap in an Oklahoma grassland ant assemblage. Ant species foraging on a 400-m2 grid of 25 tuna-fish baits were censused hourly for one 24-h period each month for 1 year. We used partial correlations to analyze
