Baited remote underwater video (BRUV) is a system used in marine biology research. By attracting fish into the field of view of a remotely controlled camera, the technique records fish diversity , abundance and behaviour of species.
Also in the assessment, geographical boundaries of different stocks or populations are defined. From the combined biological and fisheries data, the current status and condition of the stock is defined and managers use this assessment to predict how in the future, stocks will respond to varying levels of fishing pressure.

The center's research facilities are designed to enhance the health, reproduction, and reintroduction efforts of endangered species and to collect information about the general biology of raptors. The science is focused on understanding how diet, aging and environment affect the health, growth, reproduction and lifespan of the birds.
The origin of today's major Falco groups—the "typical" hobbies and kestrels, for example, or the peregrine-hierofalcon complex, or the aplomado falcon lineage—can be quite confidently placed from the Miocene-Pliocene boundary through the Zanclean and Piacenzian and just into the Gelasian, that is from 2.4 to 5.3 Mya, when the malar-striped ...
