Biology / Population Estimation
Population estimation
Introduction
Estimates of population size play a vital role in many fisheries management decisions. The numbers of fish in a stock are used to identify influences of environmental factors, human exploitation, and ultimately to identify the effectiveness of management strategies. (Van Den Avyle & Hayward 1999) The three most common methods of population estimation...

Biology / Adaptive Radiations In Evolution
In the past 300 million years, an innumerable variety of vertebrate species have evolved from the bony fishes of the early Paleozoic. At several points in evolutionary history, there have been periods of relatively rapid adaptation and expansion of organisms known as adaptive radiations. These are limited only by a speciesO adaptive potential and the adaptive opportunities of the environment. ...
