Ecological theory posits that higher species richness should be associated with greater exploitation of resources and niche packing resulting from either increasing species niche overlap or specialization of species' niches.

Into the Light: Diurnality has Evolved Multiple Times in Geckos [PDF]
Geckos are the only major lizard group consisting mostly of nocturnal species. Nocturnality is presumed to have evolved early in gecko evolution and geckos possess numerous adaptations to functioning in low light and at low temperatures. However, not all

Niche partitioning of microbial communities in riverine floodplains [PDF]
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 ...

Reserve Size And Fragmentation Alter Community Assembly, Diversity, And Dynamics [PDF]
Researchers have disputed whether a single large habitat reserve will support more species than many small reserves. However, relatively little is known from a theoretical perspective about how reserve size affects competitive communities structured by ...

Biodiversity, community structure and function of biofilms in stream ecosystems [PDF]
Multi-species, surface-attached biofilms often dominate microbial life in streams and rivers, where they contribute substantially to biogeochemical processes.

Niche partitioning in a guild of invasive mammalian predators
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

Niche partitioning shaped herbivore macroevolution through the early Mesozoic [PDF]
AbstractThe Triassic (252–201 Ma) marks a major punctuation in Earth history, when ecosystems rebuilt themselves following the devastating Permian-Triassic mass extinction. Herbivory evolved independently several times as ecosystems comprising diverse assemblages of therapsids, parareptiles and archosauromorphs rose and fell, leading to a world ...

Reproductive Interference and Niche Partitioning in Aphidophagous Insects
The range and quality of prey species differ greatly among closely related species of predators. However, the factors responsible for this diversified niche utilization are unclear.

According with niche theory the species are specialized in different ecological niches, being able to coexist as result of a differential use of resources.

Three-dimensional niche partitioning between two colonially nesting ardeid species in central China
Background Interspecific competition is known to be strongest between those species that are both closely related and sympatric. Egrets are colonially nesting wetland birds that often overlap and can therefore be expected to compete in roosting and ...
