Ontogenetic Changes in Feeding Behaviors in Tufted Capuchins. [PDF]
Am J Biol AnthropolABSTRACT Objectives Wild juvenile capuchins exhibit lower feeding success than adults, particularly for mechanically challenging foods, but ontogenetic changes in oral food processing behaviors related to this reduced success are unknown. We test how oral food processing efficiency varies across development in an experimental setting in tufted ...

Journal of Ecology, Volume 110, Issue 11, Page 2684-2700, November 2022., 2022 Our results provide important insights into the proximal mechanisms that operate during ontogeny and drive variation in mature plant size in annual herbs. Of the three traits considered (a), seed mass and duration of vegetative growth had the greatest influence on plant size at maturity (b).

Revista Alergia México, 2016 The B cell development from hematopoietic stem cells is a continuous and highly regulated process where multiple differentiation potentials are gradually lost while acquiring lineage specialized functions. At 50 years of the B cell discovery, the current knowledge of its early differentiation largely derive from the isolation and characterization of ...
