We're all familiar with the idea of extreme events. Meteorologists keep us up to date on hurricanes, floods and high temperatures. Economists watch the stock market for signs of crashes or rallies. Re...
In Plynlimon streams, brown trout (Salmo trutta L.) are widespread in the upper Wye at population densities of 0.03 to 0.32 fish m-2 and show evidence of successful recruitment in most years. In the u...
DIVER-BASED UNDER WATER SURVEY TECHNIQUES USED TO ASSESS FISH POPULATIONS AND FOULING COMMUNITY DEVELOPMENT ON OFFSHORE OIL AND GAS PLATFORM STRUCTURES

2009/5/6
In the northwestern Gulf of Mexico the most common material of opportunity for artificial reef development is the steel-jacket structure of oil and gas production platforms. Investigations of fouling ...
Why Should We Closely Monitor Fecundity in Marine Fish Populations?
fecundity intrinsic rate of population increase life history stock-recruitment reproductive potential
2008/10/21
Reproductive success, best defined as lifetime total offspring to reach maturity, is the product of the number of eggs produced (i.e., fecundity) per season, adult reproductive life span and offspring...
Seagrass nurseries contribute to coral reef fish populations
Seagrass nurseries coral reef fish populations
