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
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.

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

Niche partitioning among fur seals

2023
At Cape Gantheaume, Kangaroo Island (South Australia), adult male, lactating female and juvenile New Zealand (NZ) and Australian fur seals regularly return to the same colony, creating the potential for intra- and inter-specific foraging competition in nearby waters.

Niche saturation reveals resource partitioning among consumers

Ecology Letters, 2010
Ecology Letters (2010) 13: 338–348 Abstract More diverse communities of consumers typically use more resources, which often is attributed to resource partitioning ...

Simulated niche partitioning by bacteria

2011
A central problem in ecology concerns the number of species that inhabit a given environment. A myriad of factors are involved, including speciation and extinction rates, geographic factors, seasonal cycles, food web stability, and a significant amount of random chance.

Niche partitioning among neotropical felids

Journal of Animal Ecology
Abstract Understanding how sympatric predators coexist remains a central question in community ecology, particularly when those species are phylogenetically related obligate carnivores with similar body sizes and trophic roles.

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

Biodiversity improves water quality through niche partitioning

Nature, 2011
Excessive nutrient loading of water bodies is a leading cause of water pollution worldwide, and controlling nutrient levels in watersheds is a primary objective of most environmental policy. Over the past two decades, much research has shown that ecosystems with more species are more efficient at removing nutrients from soil and water than are ...
