Habitat use by female mallards in the lower Mississippi alluvial valley
Mallard (Anas platyrhynchos) populations in the lower Mississippi Alluvial Valley (LMAV), USA, historically averaged 1.6 million and represented the largest concentrations of wintering mallards in North America. Effective management of this wintering population requires current information on use of habitats. Accordingly, we employed...
Davis, Bruce E.; Afton, Alan D.; Cox, Robert R. Multi-state succession in wetlands: a novel use of state and transition models
The complexity of ecosystems and mechanisms of succession are often simplified by linear and mathematical models used to understand and predict system behavior. Such models often do not incorporate multivariate, nonlinear feedbacks in pattern and process that include multiple scales of organization inherent within real-world systems. Wetlands...
Zweig, Christa L.; Kitchens, Wiley M. West Virginia crayfishes (Decapoda: Cambaridae): observations on distribution, natural history, and conservation
West Virginia's crayfishes have received moderate attention since publication of Jezerinac et al.'s (1995) monograph of the state fauna. Survey efforts were initiated over the summers of 2006 and 2007 to gather voucher material for the Indiana Biological Survey's Crustacean Collection. These collections have provided new information regarding the...
Loughman, Zachary J.; Simon, Thomas P.; Welsh, Stuart A. Biogeography of Iberian freshwater fishes revisited: The roles of historical versus contemporary constraints
Aim The question of how much of the shared geographical distribution of biota is due to environmental vs. historical constraints remains unanswered. The aim of this paper is to disentangle the contribution of historical vs. contemporary factors to the distribution of freshwater fish species. In addition, it illustrates how quantifying the...
Filipe, Ana F.; Araújo, Miguel B.; Doadrio, Ignacio; Angermeier, Paul L.; Collares-Pereira, Maria J. Recovery distances of nestling Bald Eagles banded in Florida and implications for natal dispersal and philopatry
I used band recovery data to examine distances between banding and recovery locations for 154 nestling Florida Bald Eagles and discuss the implications for understanding natal dispersal and philopatry in this species. Band recoveries occurred in 23 U.S. states and five Canadian provinces between 1931–2005. Recovery distance from the natal...
Wood, Petra Bohall Defining optimal freshwater flow for oyster production: effects of freshet rate and magnitude of change and duration on eastern oysters and Perkinsus marinus infection
In coastal Louisiana, the development of large-scale freshwater diversion projects has led to controversy over their effects on oyster resources. Using controlled laboratory experiments in combination with a field study, we examined the effects of pulsed freshwater events (freshet) of different magnitude, duration, and rate of change on oyster...
LaPeyre, Megan K.; Gossman, B.; La Peyre, Jerome F. 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...
