Predaceous diving beetles in Maine: Faunal list and keys to subfamilies Predaceous diving beetles in Maine: Faunal list and keys to subfamilies
Records of predaceous diving beetles (Coleoptera: Dytiscidae) collected in Maine are summarized. These records are augmented by field surveys of beetles in Aroostook Co., Maine during 1993-95. Keys to subfamilies are presented with color plates for selected species. A list of diving beetles that have been collected near Maine (state or province) is presented so that investigators will...

The seventy-second Christmas bird count. 302. Southern Dorchester County, Md The seventy-second Christmas bird count. 302. Southern Dorchester County, Md
We located 511 Acadian Flycatcher (Empidonax virescens) nests in bottomland hardwood forest of eastern Arkansas. Microhabitat characteristics were measured and their relationship with nest success evaluated. Fifty-two percent of all nesting attempts resulted in predation. Attributes of nest placement were similar between successful and unsuccessful nests, although successful nests were...

Metal concentrations in aquatic macrophytes as influenced by soil and acidification Metal concentrations in aquatic macrophytes as influenced by soil and acidification
Bioavailability of metals to aquatic plants is dependent on many factors including ambient metal concentration, pH of soil or water, concentration of ligands, competition with other metals for binding sites, and mode of exposure. Plants may be exposed to metals through water, air, or soil, depending on growth form. This paper examines the influence of soil type under two regimens of...

The North American Amphibian Monitoring Program. [abstract] The North American Amphibian Monitoring Program. [abstract]
The North American Amphibian Monitoring Program has been under development for the past three years. The monitoring strategy for NAAMP has five main prongs: terrestrial salamander surveys, calling surveys, aquatic surveys, western surveys, and atlassing. Of these five, calling surveys were selected as one of the first implementation priorities due to their friendliness to volunteers of...

Geohydrology and quality of ground water in unconsolidated aquifers near South Bend, Indiana Geohydrology and quality of ground water in unconsolidated aquifers near South Bend, Indiana
Introduction The water supply for the City of South Bend, Indiana, and much of surrounding St. Joseph County is provided by 36 municipal and community well fields. Some of these well fields are located near known or potential sources of ground-water contamination that could affect ground-water supplies in the near future. As population and industry grow, it will be necessary to find...

Ecology and behaviour of the Alder Flycatcher Empidonax alnorum, Tyrannidae in winter Ecology and behaviour of the Alder Flycatcher Empidonax alnorum, Tyrannidae in winter
The Alder Flycatcher Empidonax alnorum (Tyrannidae) winters from Colombia and Venezuela, south to northern Argentina. We studied the species in Manu National Park, Madre de Dios, Peru. In this area the species occupies riparian zones along lowland meander rivers as well as adjacent transition zone forest in the floodplain. These habitats have a number of age-related longitudinal zones...
