Pesticides in near-surface aquifers: An assessment using highly sensitive analytical methods and tritium

In 1992, the U.S. Geological Survey (USGS) determined the distribution of pesticides in near-surface aquifers of the midwestern USA to be much more widespread than originally determined during a 1991 USGS study. The frequency of pesticide detection increased from 28.4% during the 1991 study to 59.0% during the 1992 study. This increase in pesticide detection was primarily the result of a more sens

Integration of manatee life-history data and population modeling

Aerial counts and the number of deaths have been a major focus of attention in attempts to understand the population status of the Florida manatee (Trichechus manatus latirostris). Uncertainties associated with these data have made interpretation difficult. However, knowledge of manatee life-history attributes increased and now permits the development of a population model. We describe a provision

Winter biomass and nutrient values of three seagrass species as potential foods for redheads (Aythya americana eyton) in Chandeleur Sound, Louisiana

We studied biomass and macronutrient content ofHalodule wrightii (shoalgrass) throughout the winter and ofThalassia testudinum (turtlegrass) andSyringodium filiforme (manateegrass) in January in Chandeleur Sound, LouisianaHalodule, the primary fcod of wintering redheads, had the lowest biomass of the three species on the study area in mid-winter. Macronutrient content ofHalodule did not change dur
