Nutrient additions by waterfowl to lakes and reservoirs: predicting their effects on productivity an N, and 70% of all P that entered the lake from external sources. Loads from all external sources totaled 840 mg P m. y.. Application of a nutrient load-response model to this concentration, the hydraulic load (0.25 m y.), and the water residence time (9.7 y) of Wintergreen Lake yielded an average a

Use of boreal forested wetlands by Pacific loons (, Lawrence) and horned grebes (, L.): relations wily modeled by linear and quadratic functions of shoreline length, color, pH, calcium and total phosphorus. Horned grebe abundance could not be modeled with this approach. The statistical techniques known collectively as generalized linear models provided a framework for the development of models for

Cormorant (, [L]) populations and patterns of abundance at breeding and feeding sites in Northern Ir in other habitats and at other times of the year are less certain. This study establishes the long term and regional patterns of abundance at breeding and feeding localities, which might in turn be related to diet.

Aquatic bird densities in two coastal lagoon systems in Chiapas State, Mexico, a preliminary assessmbodies ranged from 102.5 to 847.5 ha. Salinity varied seasonally being the lowest in July during the rainy season (1.0%o) and highest in February (35.8%0). The waters are hypertrophic with total phosphorus concentrations as high 900 mg m..
