These changes occur at specific stages of development. An important developmental process is the maturation of motor control by which the body acquires new movements or refines movements already present.

Brazilian Journal of Biology, 2001 Many streams and large rivers present higher ichthyoplankton densities at night. However, in some rivers this does not occur and larvae are equally abundant during the day. Larval drift diel variation is an important information for planning sampling programs for evaluating larval distribution and production.

The Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Ecology and Evolution, Volume 16, Issue 7, July 2026.We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.
