Foraging niche partitioning in sympatric seabird populations [PDF]
Scientific Reports, 2021 AbstractSympatric species must sufficiently differentiate aspects of their ecological niche to alleviate complete interspecific competition and stably coexist within the same area. Seabirds provide a unique opportunity to understand patterns of niche segregation among coexisting species because they form large multi-species colonies of breeding ...

Niche partitioning in a guild of invasive mammalian predators
Ecological Applications, 2022 AbstractPredators compete aggressively for resources, establishing trophic hierarchies that influence ecosystem structure. Competitive interactions are particularly important in invaded ecosystems where introduced predators can suppress native prey species. We investigated whether niche partitioning exists within a guild of invasive mammalian predators

Dynamics of Niche Width and Resource Partitioning [PDF]
American Journal of Sociology, 2001 This article examines the effects of crowding in a market center on rates of change in organizational niche width and on organizational mortality. It proposes that, although firms with wide niches benefit from risk spreading and economies of scale, they are simultaneously exposed to intense competition.

A Hierarchical Niche Structure, Not Niche Partitioning, Organizes a Seasonally Dynamic Flea Community. [PDF]
Ecol EvolInteractions in single-host–parasite systems provide a tractable framework for understanding the ecological mechanisms that maintain community stability. Here, we integrated network topology, multidimensional niche analysis, and functional group delineation to investigate the adaptive strategies and assembly rules of a 12-species flea community on ...

Niche Partitioning Along an Environmental Gradient [PDF]
SIAM Journal on Applied Mathematics, 2014 Biological systematics studies suggest that species are discretized in niche space. That is, rather than seeing a continuum of organism types with respect to continuous environmental variations, observers instead find discrete species or clumps of species, with one clump separated from another in niche space by a gap.

Niche partitioning by resource size in the gut microbiome
Niche partitioning promotes diversity of the human gut microbiota. However, the molecular basis of resource specialization and niche separation in the gut remains poorly understood. Here we show that structural differences in glycan transporters drive members of the genus Bacteroides, common human gut commensals, to specialize on distinct chain lengths

Counting niches: Abundance‐by‐trait patterns reveal niche partitioning in a Neotropical forest [PDF]
Ecology, 2020 Abstract Tropical forests challenge us to understand biodiversity, as numerous seemingly similar species persist on only a handful of shared resources. Recent ecological theory posits that biodiversity is sustained by a combination of species differences reducing interspecific competition and species similarities increasing time to ...

Niche partitioning in a sympatric cryptic species complex [PDF]
Ecology and Evolution, 2016 AbstractCompetition theory states that multiple species should not be able to occupy the same niche indefinitely. Morphologically, similar species are expected to be ecologically alike and exhibit little niche differentiation, which makes it difficult to explain the co‐occurrence of cryptic species.

Energetic efficiency of foraging mediates bee niche partitioning [PDF]
Ecology, 2021 AbstractRevitalizing our understanding of species distributions and assembly in community ecology requires greater use of functional (physiological) approaches based on quantifiable factors such as energetics. Here, we explore niche partitioning between bumble and honey bees by comparing a measure of within‐patch foraging efficiency, the ratio of ...

Niche partitioning of microbial communities in riverine floodplains [PDF]
Scientific Reports, 2019 AbstractRiverine floodplains exhibit high floral and faunal diversity as a consequence of their biophysical complexity. Extension of such niche partitioning processes to microbial communities is far less resolved or supported. Here, we evaluated the responses of aquatic biofilms diversity to environmental gradients across ten riverine floodplains with ...
