For practical reasons, all ramets of a clonal plant are considered to be independent individuals in demographical studies, but there are reports that ramet ontogeny is affected by their position in a ...

The way in which density-dependent effects are partitioned amongst survival, growth and dispersal are key in determining the temporal and spatial dynamics of populations. Here we propose a mechanistic ...

Human antibodies to bacterial polyaaccharides consist primarily of IgG and are largely restricted to the IgG2 subclass. We examined the ontogeny of the IgG subclass response to pneumococcal ...

Biologists are learning how to turn on the genes that make our cells young. With them, we might repair our bones. Replenish our blood. Replace our limbs. And maybe some brain cells too. The cells come ...

Endothelial cell-selective adhesion molecule, a surface marker for hematopoietic stem cells and vascular endothelial cells, played an essential role in the ontogeny of hematopoiesis in mice, ...
