This acoustic–optical survey method provides data that are vital for the assessment of fish species in ecosystems which are difficult, or impossible for certain species, to survey with existing methods.
We use acoustic recordings collected over broad time and space scales to investigate whether global variability in echolocation frequency could make clear population structure in Blainville's beaked whale.
Better understanding of the vocal behavior of cetaceans in the name of developing automated passive acoustic cetacean tracking, localization, and classification techniques.
A goal of this work is to effectively balance sustainability risks with fishery production to mitigate overfishing likelihoods and to increase the probability of sustainable fisheries.
We use a biophysical modeling approach to simulate recruitment of red snapper across the entire Southeastern US region, and quantify rates of larval exchange across management jurisdictions.
Life history characteristics pertaining to the sexual maturation and age and growth of the yellowtail emperor were derived and exploitation rate was considered.
