Seasonal niche differentiation among closely related marine bacteria [PDF]
Bacteria display dynamic abundance fluctuations over time in marine environments, where they play key biogeochemical roles. Here, we characterized the seasonal dynamics of marine bacteria in a coastal oligotrophic time series station, tested how similar ...

Salt tolerance-based niche differentiation of soil ammonia oxidizers
Abstract Ammonia oxidizers are key players in the global nitrogen cycle, yet little is known about their ecological performances and adaptation strategies for growth in saline terrestrial ecosystems. This study combined 13C-DNA stable-isotope probing (SIP) microcosms with amplicon and shotgun sequencing to reveal the composition and ...

Identifying the niche controlling melanocyte differentiation [PDF]
Melanocytes present in hair follicles are responsible for their pigmentation. Melanocyte differentiation and hair pigmentation depend on the stem cell factor (SCF)/c-Kit signaling pathway, but the niche that regulates melanocyte differentiation is not well characterized. In this issue of Genes & Development, Liao and colleagues (pp.

Understanding the mechanisms that drive community assembly in species‐rich tropical forest remains a fundamental challenge in ecology. Here, we integrated multivariate functional trait dimensions, phylogeny and metabolomics to test fundamental ...

A role for gut microbiota in host niche differentiation [PDF]
AbstractIf gut microbes influence host behavioral ecology in the short term, over evolutionary time, they could drive host niche differentiation. We explored this possibility by comparing the gut microbiota of Madagascar’s folivorous lemurs from Indriidae and Lepilemuridae.

Niche differentiation of sulfur-oxidizing bacteria (SUP05) in submarine hydrothermal plumes
Hydrothermal plumes transport reduced chemical species and metals into the open ocean. Despite their considerable spatial scale and impact on biogeochemical cycles, niche differentiation of abundant microbial clades is poorly understood.

Differentiation capacities of PS-clusters, adult pituitary stem/progenitor cell clusters located in the parenchymal-niche, of the rat anterior lobe. [PDF]
Pituitary endocrine cells are supplied by Sox2-expressing stem/progenitor cells in the anterior lobe of the adult pituitary. In relation to their microenvironment ("niche"), SOX2-positive cells exist in two types of niches; the marginal cell layer-niche ...

Constrained niching using differential evolution [PDF]
Abstract The work presented here involves development and detailed investigations of niching methods for multimodal optimization of constrained functions. There is a lack of investigations in the literature on constrained multimodal optimization, hence a number of constrained niching algorithms have been developed here that leverage existing ...

Niche differentiation, reproductive interference, and range expansion. [PDF]
Abstract Understanding species distributions and predicting future range shifts requires considering all relevant abiotic factors and biotic interactions. Resource competition has received the most attention, but reproductive interference is another widespread biotic interaction that could influence species ranges.
