Testing for changes in rate of evolution and position of the climatic niche of clades [PDF]
Mammal Review, 2022 There is solid recognition that phylogenetic effects must be acknowledged to appreciate climatic niche variability among species clades properly. Yet, most currently available methods either work at the intra-specific level (hence they ignore phylogeny ...

Oecologia, 2018 The regional occupancy and local abundance of species are thought to be strongly correlated to their body size, niche breadth and niche position. The strength of the relationships among these variables can also differ between different organismal groups.

Spindle positioning in the stem cell niche [PDF]
WIREs Developmental Biology, 2011 AbstractStem cells are the source of differentiated cells that constitute tissues and organs. Two fundamental characteristics of stem cells are their abilities to self‐renew stem cell identity and to produce differentiated cells, the balance of which can be achieved by asymmetric stem cell division.

The probabilistic niche model reveals the niche structure and role of body size in a complex food web. [PDF]
PLoS ONE, 2010 The niche model has been widely used to model the structure of complex food webs, and yet the ecological meaning of the single niche dimension has not been explored.

The Role of Gram-Positive Surface Proteins in Bacterial Niche- and Host-Specialization [PDF]
Frontiers in Microbiology, 2020 Gram-positive bacterial pathogens have an array of proteins on their cell surface that mediate interactions with the host environment. In particular, bacterial cell wall-associated (CWA) proteins play key roles in both colonization and pathogenesis.
