Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.
