Nitrogen and phosphorus excretion by detritivorous gizzard shad in a reservoir ecosystem
The detritivorous fish, gizzard shad (Dorosoma cepedianum), provides nutrients to phytoplankton in reservoirs by ingesting organic detritus associated with sediments and excreting substantialExpand

Assessing How Fish Predation and Interspecific Prey Competition Influence a Crayfish Assemblage
Allstract. In northern Wisconsin lakes, the introduced crayfish Orconectes rusticus is replacing 0. propinqaus, a previous invader, and 0. virilis, a native crayfish. Herein, we explore how fishExpand

Overwinter growth and survival of age-0 largemouth bass (Micropterus salmoides): revisiting the role of body size
How large size affects overwinter growth and survival of age-0 fish may vary as a function of food, predation, and energetic condition. During two winters in Ohio, we assessed how these factorsExpand

Protracted Reproduction in Sunfish: the Temporal Dimension in Fish Recruitment Revisited
Understanding how life histories influence reproductive success under un- certain conditions is necessary to predict population dynamics. For many organisms, pro- tracted reproduction may increaseExpand
