Sensory Biology of the Franciscana (Pontoporia blainville, 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 ...

Fisher-based assessments of sea turtle bycatch in small-scale fisheries in Pacific Mexico

Endangered Species Research
Reducing bycatch of sea turtles and other protected species in artisanal fisheries depends on first understanding where, how, and to what extent bycatch is occurring. We implemented rapid bycatch assessments (RBAs)—i.e.

Assessing incidental bycatch of seabirds in Norwegian coastal commercial fisheries: Empirical and methodological lessons

Global Ecology and Conservation, 2015
With diminishing seabird populations and little knowledge on incidental bycatch in fisheries in the Northeast Atlantic, this study aimed to screen seabird bycatch in Norwegian coastal fisheries in 2009. The purpose was to 1) quantify magnitude of seabird
