Does winter region affect spring arrival time and body mass of king eiders in northern Alaska?
Events during the non-breeding season may affect the body condition of migratory birds and influence performance during the following breeding season. Migratory birds nesting in the Arctic often rely on endogenous nutrients for reproductive efforts, and are thus potentially subject to such carry-over effects. We tested whether king eider (...
Powell, Abby N.; Oppel, Steffen Does mobility explain variation in colonisation and population recovery among stream fishes?
1. Colonisation and population recovery are crucial to species persistence in environmentally variable ecosystems, but are poorly understood processes. After documenting movement rates for several species of stream fish, we predicted that this variable would influence colonisation rates more strongly than local abundance, per cent occupancy, body...
Angermeier, Paul L.; Albanese, Brett; Peterson, James FishTraits Database
The need for integrated and widely accessible sources of species traits data to facilitate studies of ecology, conservation, and management has motivated development of traits databases for various taxa. In spite of the increasing number of traits-based analyses of freshwater fishes in the United States, no consolidated database of traits of this...

Mather, Martha E.; Parrish, Donna L.; Dettmers, John M. Vegetation effects on fish distribution in impounded salt marshes
We compared the density and biomass of resident fish in vegetated and unvegetated flooded habitats of impounded salt marshes in the northern Indian River Lagoon (IRL) Estuary of east-central Florida. A 1-m2 throw trap was used to sample fish in randomly located, paired sample plots (n = 198 pairs) over 5 seasons in 7 impoundments. We...
Stolen, Eric D.; Collazo, Jaime; Percival, H. Franklin Summer movements of sub-adult brook trout, landlocked Atlantic salmon, and smallmouth bass in the Rapid River, Maine
Summer movement patterns and spatial overlap of native sub-adult brook trout (Salvelinus fontinalis), non-native landlocked Atlantic salmon (Salmo salar), and non-native smallmouth bass (Micropterus dolomieu) in the Rapid River, Maine, were investigated with radio telemetry in 2005. Fishes were captured by angling, surgically implanted with radio...
Jackson, Casey A.L.; Zydlewski, Joseph D. Bycatch of the endangered pallid sturgeon (Scaphirhynchus albus) in a commercial fishery for shovelnose sturgeon (Scaphirhynchus platorynchus)
We quantified the bycatch of pallid sturgeon Scaphirhynchus albus in Tennessee's shovelnose sturgeon (Scaphirhynchus platorynchus) fishery by accompanying commercial fishers and monitoring their catch on five dates in spring 2007. Fishers were free to keep or discard any sturgeon they collected in their gillnets and trotlines and we were afforded...
Bettoli, Phillip William; Casto-Yerty, M.; Scholten, G.D.; Heist, Edward J. Vulnerability and adaptation to climate-related fire impacts in rural and urban interior Alaska
This paper explores whether fundamental differences exist between urban and rural vulnerability to climate-induced changes in the fire regime of interior Alaska. We further examine how communities and fire managers have responded to these changes and what additional adaptations could be put in place. We engage a variety of social science methods,...
Trainor, Sarah F.; Calef, Monika; Natcher, David; Chapin, F. Stuart; McGuire, A. David; Huntington, Orville; Duffy, Paul A.; Rupp, T. Scott; DeWilde, La'Ona; Kwart, Mary; Fresco, Nancy; Lovecraft, Amy Lauren The ecology, restoration, and management of southeastern floodplain ecosystems: a synthesis
Floodplain ecosystems of the southeastern United States provide numerous services to society, but hydrologic and geomorphic alterations, agricultural practices, water quality and availability, and urban development continue to challenge restorationists and managers at multiple spatial and temporal scales. These challenges are further exacerbated...
King, Sammy L.; Sharitz, Rebecca R.; Groninger, John W.; Battaglia, Loretta L. Survival and passage of ingested New Zealand mudsnails through the intestinal tract of rainbow trout
We conducted laboratory trials to determine the transit time and survival of New Zealand mudsnails Potamopyrgus antipodarum in the gastrointestinal tract of rainbow trout Oncorhynchus mykiss. To assess the rate of snail passage, we force-fed groups of fish a known quantity of snails and then held them in tanks. At selected intervals we removed...
Bruce, R. Louise; Moffitt, Christine M.; Dennis, Brian Site characteristics and prey abundance at foraging sites used by Lesser Scaup (Aythya affinis) wintering in Florida
We examined site characteristics and prey abundances where wintering Aythya affinis (Lesser Scaup; hereafter scaup) foraged within three regions of the Indian River Lagoon system in central Florida. We observed that scaup concentrated in the Indian and Banana rivers; however, density of prey items did not differ between foraging sites and random...
Herring, Garth; Collazo, Jaime Use of a fishery-independent trawl survey to evaluate distribution patterns of subadult sharks in Georgia
We investigated the utility of a fishery-independent trawl survey for assessing a potential multispecies shark nursery in Georgia's nearshore and inshore waters. A total of 234 subadult sharks from six species were captured during 85 of 216 trawls. Catch rates and size distributions for subadult sharks and the ratio of neonates to juveniles were...
