Dental ontogeny in pliocene and early pleistocene hominins.
Until recently, our understanding of the evolution of human growth and development derived from studies of fossil juveniles that employed extant populations for both age determination and comparison.

The Early Ontogeny of Reason Giving [PDF]
Abstract The key context within which preschool children learn to justify beliefs with reasons is collaborative problem-solving and decision-making with peers, including in the moral domain, in which they engage with another coequal mind in a cooperative spirit.

Aquaculture of marine ornamental fish could potentially reduce the fishing pressure on wild stocks by the global aquarium trade, but its expansion is often constrained by the limited understanding on the biology and early life history of candidate ...

Effects of praziquantel on common carp embryos and larvae
This study aimed to assess the toxicity of praziquantel (anthelmintic drug) in different developmental stages of common carp (Cyprinus carpio) based on mortality, early ontogeny, growth, oxidative stress, antioxidant enzymes, histology and behaviour ...

The ontogeny of early language discrimination: Beyond rhythm
Infants can discriminate languages that belong to different rhythmic classes at birth. The ability to perform within-class discrimination emerges around the fifth month of life. The cues that infants use to discriminate between prosodically close languages remain elusive.

Skeletal ontogeny of the caudal complex in Caspian kutum, Rutilus kutum (Kamensky, 1901) (Teleostei: Cyprinidae) during early development [PDF]
Study of skeletal ontogeny during early development is crucial in a successful larviculture. In this study, ontogeny of the caudal complex skeleton in Caspian kutum, Rutilus kutum, was studied from hatching up to 50-day post hatching (dph).

Early development and growth of sterlet (Acipenser ruthenus) in the Czech Republic
Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions in the Czech Republic. The embryos hatched when reaching a mean total length (TL) of 9.0 mm.

The ontogeny of memory persistence and specificity
Interest in the ontogeny of memory blossomed in the twentieth century following the initial observations that memories from infancy and early childhood are rapidly forgotten.

In supportive breeding programs for wild salmon populations, stocked parr experience higher mortality rates than wild ones. Among other aspects of phenotype, the gut microbiota of artificially raised parr differs from that of wild parr before stocking ...

Compensatory development and costs of plasticity: larval responses to desiccated conspecifics. [PDF]
Understanding constraints on phenotypic plasticity is central to explaining its evolution and the evolution of phenotypes in general, yet there is an ongoing debate on the classification and relationships among types of constraints.
