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 ...

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 and the role of intraspecific niche variation in structuring a guild of generalist anurans [PDF]

Royal Society Open Science, 2017
Intra-population niche differences in generalist foragers have captured the interest of ecologists, because such individuality can have important ecological and evolutionary implications. Few researchers have investigated how these differences affect the relationships among ecologically similar, sympatric species.

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

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

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 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.

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 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.

Overlap and partitioning of the ecological and isotopic niches

Oikos, 2010
Recently, it was proposed that stable isotope patterns can be used to quantify the width of the ecological niche of animals. However, the potential effects of habitat use on isotopic patterns of consumers have not been fully explored and consequently isotopic patterns may yield deceptive estimates of niche width.
