The phrase "availability of niche" is correct and usable in written English.
It can be used when discussing the presence or accessibility of a specific market segment or specialized area within a broader context.
Example: "The availability of niche products has increased significantly in recent years, catering to diverse consumer preferences."
Alternatives: "accessibility of niche" or "presence of niche".
In addition, differences in the availability of niche-specific Wnt agonists and antagonists might distinctly modulate CSC self-renewal and differentiation in different cancer types.
However, randomization tests, which estimated the effects of differential habitat availability on niche breadth for native and introduced populations, were unable to reject the hypothesis that the observed niche expansion resulted solely from differences in available habitat between native and introduced ranges.
Differences in migration and matrix interaction could cause ADAM8−/− thymocytes to occupy certain thymic microenvironments for longer periods of time than thymocytes that express functional ADAM8 and as a result alter the availability of intrathymic niche space.
However, Hurlbert [ 22] emphasized that not only proportional utilization, but also the proportional availability of each niche should be taken into account.
To construct a dataset to pursue the study of adaptations to high temperature and high salinity, we have selected a total of 192 prokaryotic (153 bacterial and 39 archaeal) proteomes based on the availability of environmental niche descriptors at the time of data collection.
The adaptation of microbes to new hosts, the failure to eradicate them, and continued availability of appropriate host niche, could lead to permanent fixation through genetic changes over time.
Some authors have argued that in these highly disturbed, non-equilibrium communities, classic theories of species coexistence through niche differentiation are less realistic than models of coexistence based on lottery recruitment and the availability of transient niches [ 14- 19].
Similarly, calculations of d' or other niche breadth measures are based on the implicit assumption that each species adjusts its interactions according to the availability of partners (niches), irrespective of morphological or behavioral constraints.
Hybrid speciation appears to be facilitated by several additional factors, for example, availability of a suitable ecological niche or development of appropriate fitness (Rieseberg 1997; Mallet 2007).
It is possible that development of bone metastases is also inhibited by BPs modifying the size and/or availability of the metastatic (osteoblastic) niche.
These three scenarios describe a range of possible results of climate change over the next century that may play a role in the niche availability of chimpanzees in Cameroon and Nigeria.
