Identifying the niche controlling melanocyte differentiation [PDF]
Genes & Development, 2017 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.

Niche differentiation, reproductive interference, and range expansion. [PDF]
Ecol Lett, 2023 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.

A Spatial Signal of Niche Differentiation in Tropical Forests
The American NaturalistAbstractExplaining diversity in tropical forests remains a challenge in community ecology. Theory tells us that species differences can stabilize communities by reducing competition, while species similarities can promote diversity by reducing fitness differences and thus prolonging the time to competitive exclusion.

Niche differentiation between diploid and hexaploid Aster amellus [PDF]
Oecologia, 2008 The maintenance of separated diploid and polyploid populations within a contact zone is possible due to both prezygotic and postzygotic isolation mechanisms. Niche differentiation between two cytotypes may be an important prezygotic isolating mechanism and can be studied using reciprocal transplant experiments.

Geometry of ecological coexistence and niche differentiation. [PDF]
Phys Rev E, 2023 A fundamental problem in ecology is to understand how competition shapes biodiversity and species coexistence. Historically, one important approach for addressing this question has been to analyze Consumer Resource Models (CRMs) using geometric arguments. This has led to broadly applicable principles such as Tilman’s

The white matter is a pro-differentiative niche for glioblastoma [PDF]
Nature Communications, 2021 AbstractGlioblastomas are hierarchically organised tumours driven by glioma stem cells that retain partial differentiation potential. Glioma stem cells are maintained in specialised microenvironments, but whether, or how, they undergo lineage progression outside of these niches remains unclear.

Engineering the niche to differentiate and deploy cardiovascular cells [PDF]
Current Opinion in Biotechnology, 2022 Applications for stem cells have ranged from therapeutic interventions to more conventional screening and in vitro modeling, but significant limitations to each is due to the lack of maturity from decades old monolayer protocols. While those methods remain the 'gold standard,' newer three-dimensional methods, when combined with engineered niche, stand ...

Constrained niching using differential evolution [PDF]
Swarm and Evolutionary Computation, 2019 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 ...

A role for gut microbiota in host niche differentiation [PDF]
The ISME Journal, 2020 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.
