Niche Differentiation among Sympatric Australian Dasyurid Carnivores [PDF]

Journal of Mammalogy, 2000
Niche differentiation occurred on 3 dimensions in a size-structured guild of marsupial carnivores (Marsupialia: Dasyuridae) that included the Tasmanian devil (Sarcophilus laniarius), spotted-tailed quoll (Dasyurus maculatus), and eastern quoll (D. viverrinus).

Evaluation ecological niche between Platyceps rhodorachis and P. karelini (Serpentes: Colubridae) in Iran [PDF]

Iranian Journal of Animal Biosystematics, 2021
Platyceps rhodorachis (JAN, 1863) and P. karelini (BRANDT, 1838) are both members of the P. rhodorachis complex species, which is widely distributed in Iran and includes many local populations in the country. These two species are molecularly and to some

Niche Differentiation of Comammox Nitrospira in the Mudflat and Reclaimed Agricultural Soils Along the North Branch of Yangtze River Estuary

Frontiers in Microbiology, 2021
The discovery of complete ammonia oxidation (comammox), oxidizing ammonia to nitrate via nitrite in a single organism, has redefined the traditional recognition of the two-step nitrification driven by two functional groups (ammonia-oxidizing and nitrite ...

Hearing sensitivity: An underlying mechanism for niche differentiation in gleaning bats

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance While numerous studies have focused on the ecological factors allowing for niche differentiation and thus species coexistence, the role of differentiation in species’ sensory abilities has received less attention.

Wnt signaling-mediated redox regulation maintains the germ line stem cell differentiation niche

eLife, 2015
Adult stem cells continuously undergo self-renewal and generate differentiated cells. In the Drosophila ovary, two separate niches control germ line stem cell (GSC) self-renewal and differentiation processes.

Decomposing the Causes for Niche Differentiation Between Species Using Hypervolumes

Frontiers in Ecology and Evolution, 2020
Hutchinson’s n-dimensional hypervolume concept holds a central role across different fields of ecology and evolution. The question of the amount of hypervolume overlap and differentiation between species is of great interest to understand the processes ...

Niches within a niche: ecological differentiation of subterranean amphipods across Europe's interstitial waters [PDF]

Ecography, 2019
Species that successfully colonized subterranean environments are subject to two opposing selection processes. Stringent abiotic factors select for convergent adaptations, such as loss of eyes and pigments, while interspecific competition drives between‐species divergence.

Transposon Dysregulation Modulates dWnt4 Signaling to Control Germline Stem Cell Differentiation in Drosophila. [PDF]

PLoS Genetics, 2016
Germline stem cell (GSC) self-renewal and differentiation are required for the sustained production of gametes. GSC differentiation in Drosophila oogenesis requires expression of the histone methyltransferase dSETDB1 by the somatic niche, however its ...

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 ...

EGFR Signaling Termination via Numb Trafficking in Ependymal Progenitors Controls Postnatal Neurogenic Niche Differentiation

Cell Reports, 2019
Summary: Specialized microenvironments, called niches, control adult stem cell proliferation and differentiation. The brain lateral ventricular (LV) neurogenic niche is generated from distinct postnatal radial glial progenitors (pRGPs), giving rise to ...
