Reductions in the dietary niche of southern sea otters (Enhydra lutris nereis) from the Holocene to the Anthropocene. [PDF]
, 2020 The sea otter (Enhydra lutris) is a marine mammal hunted to near extinction during the 1800s. Despite their well-known modern importance as a keystone species, we know little about historical sea otter ecology.

Determining trophic niche width: a novel approach using stable isotope analysis [PDF]
, 2004 1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.

The expanded diversity of methylophilaceae from Lake Washington through cultivation and genomic sequencing of novel ecotypes. [PDF]
, 2014 We describe five novel Methylophilaceae ecotypes from a single ecological niche in Lake Washington, USA, and compare them to three previously described ecotypes, in terms of their phenotype and genome sequence divergence.

Predicting Avian Influenza Co-Infection with H5N1 and H9N2 in Northern Egypt. [PDF]
, 2016 Human outbreaks with avian influenza have been, so far, constrained by poor viral adaptation to non-avian hosts. This could be overcome via co-infection, whereby two strains share genetic material, allowing new hybrid strains to emerge. Identifying areas

Laboratory measures of boldness correlate with ecological niche in threespine stickleback
Ecology 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.

Ecology and co-existence of two endemic day gecko (Phelsuma) species in Seychelles native palm forest [PDF]
, 2011 In island ecosystems, reptiles play diverse ecological roles as a result of niche broadening, which increases potential niche overlap between species. Ecological niche partitioning is a means of reducing direct competition between coexisting species and ...

Acknowledging uncertainty in evolutionary reconstructions of ecological niches
Ecology 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 ...
