Application of novel encounter and predation models to the natural behavior of slimy sculpin Cottus cognatus Application of novel encounter and predation models to the natural behavior of slimy sculpin Cottus cognatus

Sculpins play a critical mid-trophic role in lacustrine food webs, converting production by benthic and migrating pelagic invertebrates into biomass available to higher trophic levels. Although sculpin diets and habitat choices are relatively well described, much less is known about their in situ behavior which governs trophic interactions and, in part, prey behavior. We measured the...

Thermal habitat use of lake trout in Lake Erie Thermal habitat use of lake trout in Lake Erie

Understanding the thermal habitat use of fish populations is vital for effective rehabilitation or management, particularly in the face of climate change, given limited thermal tolerances of some species. In Lake Erie, lake trout (Salvelinus namaycush) rehabilitation efforts by means of stocking have been ongoing for four decades. However, high water temperatures and lengthening periods...

Assessing low-dose copper treatment for dreissenid mussels: Effects on nontarget organisms Assessing low-dose copper treatment for dreissenid mussels: Effects on nontarget organisms

Zebra mussels (Dreissena polymorpha), an invasive dreissenid mussel, have been established and caused considerable effects in many North American aquatic ecosystems. In response, copper-based pesticides have been used to manage zebra mussel populations. We evaluated the effects of a low-dose (60 µg Cu/L for 10 d) copper-based molluscicide for zebra mussel suppression on nontarget species...

Evaluating the Design of the Waterfowl Breeding Population and Habitat Survey

The Waterfowl Breeding Population and Habitat Survey (WBPHS) is a primary source of waterfowl population status and trend information for management of ducks in North America. The survey has not been reviewed in several decades, and since the last review new analysis approaches and information needs have created a need to reassess the design, scope of inference, and analysis of the survey to...
