Global analysis of ecological niche conservation and niche shift in exotic populations of monkeyflowers (Mimulus guttatus, M. luteus) and their hybrid (M. x robertsii) [PDF]

open access: yes, 2020
Background Hybridisation associated with biological invasions may generate new phenotypic combinations, allowing hybrids to occupy new ecological niches. To date, few studies have assessed niche shifts associated with hybridisation in recently introduced

A network approach reveals surprises about the history of the niche

open access: yesEcosphere, 2016
The ecological niche is a prominent theoretical concept in many ecological fields, central to ecological understanding of species interactions and community structure.

Niche Divergence at Intraspecific Level in the Hyrcanian Wood Frog, Rana pseudodalmatina: A Phylogenetic, Climatic, and Environmental Survey

open access: yesFrontiers in Ecology and Evolution, 2022
The role of ecological niche divergence in lineage speciation has recently stimulated the interest of evolutionary biologists and ecologists. Phylogenetic analysis has revealed that the Hyrcanian wood frog, Rana pseudodalmatina, has diverged into two ...

Laboratory measures of boldness correlate with ecological niche in threespine stickleback

open access: yesEcology and Evolution, 2022
Research on among individual variation in behavior has increased rapidly in recent years. It is intuitively appealing that variation in the behavior of individuals has ecological consequences, for example, on trophic niche.

Little ecological divergence associated with speciation in two African rain forest tree genera [PDF]

open access: yes, 2011
Background The tropical rain forests (TRF) of Africa are the second largest block of this biome after the Amazon and exhibit high levels of plant endemism and diversity. Two main hypotheses have been advanced to explain speciation processes that have led

Acknowledging uncertainty in evolutionary reconstructions of ecological niches

open access: yesEcology and Evolution, 2020
Reconstructing ecological niche evolution can provide insight into the biogeography and diversification of evolving lineages. However, comparative phylogenetic methods may infer the history of ecological niche evolution inaccurately because (a) species ...

Invasion success of a global avian invader is explained by within-taxon niche structure and association with humans in the native range [PDF]

open access: yes, 2015
Aim To mitigate the threat invasive species pose to ecosystem functioning, reli- able risk assessment is paramount. Spatially explicit predictions of invasion risk obtained through bioclimatic envelope models calibrated with native species distribution ...

Ecological model to predict potential habitats of Oncomelania hupensis, the intermediate host of Schistosoma japonicum in the mountainous regions, China [PDF]

open access: yes, 2015
Schistosomiasis japonica is a parasitic disease that remains endemic in seven provinces in the People's Republic of China (P.R. China). One of the most important measures in the process of schistosomiasis elimination in P.R.

Evaluating Potential Distribution and Niche Divergence among Populations of the World’s Largest Living Damselfly, Megaloprepus caerulatus (Drury, 1782)

open access: yesDiversity, 2022
Megaloprepus caerulatus is a Neotropical species with a highly specialised niche, found from Mexico to Bolivia, primarily in mature tropical forests lower than 1500 masl. It is also the damselfly with the largest wingspan in the world.

The relationship between niche breadth and geographic range size in African Horseshoe bats (Rhinolophidae, Chiroptera) [PDF]

open access: yes, 2011
According to Brown's hypothesis, generalists have high niche breadth and can tolerate a wide variety of environmental conditions resulting in large geographic range sizes. Conversely, specialists have low niche breadth and small range sizes.
