Habitat use of American eel (Anguilla rostrata) in a tributary of the Hudson River, New York Habitat use of American eel (Anguilla rostrata) in a tributary of the Hudson River, New York
American eel Anguilla rostrata populations are declining over much of their native range. Since American eels spend extended periods in freshwater, understanding their habitat requirements while freshwater residents is important for the management and conservation of this species. As there is little information on American eel habitat use in streams, the ontogenetic, diel, and seasonal...

Diel variation in summer habitat use, feeding periodicity, and diet of subyearling Atlantic salmon in the Salmon River Basin, New York Diel variation in summer habitat use, feeding periodicity, and diet of subyearling Atlantic salmon in the Salmon River Basin, New York
The habitat use, diet composition, and feeding periodicity of subyearling Atlantic salmon (Salmo salar) was examined during both day and night periods during summer in tributaries of Lake Ontario. The amount of cover used was the major habitat variable that differed between day and night periods in both streams. At night subyearling Atlantic salmon were associated with significantly less...

Importance of the National Petroleum Reserve-Alaska for aquatic birds Importance of the National Petroleum Reserve-Alaska for aquatic birds
We used data from aerial surveys (1992–2010) of >100,000 km2 and ground surveys (1998–2004) of >150 km2 to estimate the density and abundance of birds on the North Slope of Alaska (U.S.A.). In the ground surveys, we used double sampling to estimate detection ratios. We used the aerial survey data to compare densities of birds and Arctic fox (Vulpes lagopus), the major nest predator of...

Predicting breeding shorebird distributions on the Arctic Coastal Plain of Alaska Predicting breeding shorebird distributions on the Arctic Coastal Plain of Alaska
The Arctic Coastal Plain (ACP) of Alaska is an important region for millions of migrating and nesting shorebirds. However, this region is threatened by climate change and increased human development (e.g., oil and gas production) that have the potential to greatly impact shorebird populations and breeding habitat in the near future. Because historic data on shorebird distributions in the...

Interactions between invasive round gobies (Neogobius melanostomous) and fantail darters (Etheostoma flabellare) in a tributary of the St. Lawrence River, New York, USA Interactions between invasive round gobies (Neogobius melanostomous) and fantail darters (Etheostoma flabellare) in a tributary of the St. Lawrence River, New York, USA
The initial, rapid expansion of the invasive round goby (Neogobius melanostomus) throughout the Great Lakes drainage was largely confined to lentic systems. We recently observed round gobies ascending two tributaries of the St. Lawrence River. The expansion of gobies into small lotic environments may place ecologically similar species at risk. Fantail darter (Etheostoma flabellare) is...

Habitat use and diet composition of juvenile Atlantic salmon in a tributary of Lake Ontario Habitat use and diet composition of juvenile Atlantic salmon in a tributary of Lake Ontario
The habitat use and diet of juvenile Atlantic salmon Salmo salar was examined in the South Sandy Creek drainage that discharges into eastern Lake Ontario. Subyearling salmon were stocked in early May during two consecutive years, and habitat and diet evaluations were made in mid-July and mid-October in 2005 and 2006. Both subyearling and yearling Atlantic salmon occupied deeper and...
