early body shape changes of beluga sturgeon were studied using landmark-based geometric morphometric approach to recognize its allometric growth pattern. sampling was done from hatching up to 50 days post hatching (dph). left side of specimens were photographed using digital camera and nine landmark points were digitized on two-dimensional images. total length (ti) was measured using the softwa...
Abstract Large mammals at northern latitudes show annual cycles of body mass gain in summer and loss winter. The amplitude seasonal timing these may vary through ontogeny depending on trade‐offs toward investments structural growth versus fat storage, reproduction, future survival. Despite this knowledge, there is no detailed model how the seasonality develops ontogeny. Here, we define a new th...
introduction: - significant increase in usage of silver nanoparticles (agnps) in consumer products, has increased its exposures to human and animals. although there are some reports regarding the effects of agnps on complex organisms, no report was found as to its effects on neurobehavioral ontogeny. methods: to investigate the effects of maternal exposure to agnps on development of neurobehavi...
