Midwater Fish Assemblages and Seamounts
2008Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features ...

Fish assemblages in the Barents Sea
Marine Biology Research, 2006Abstract Fish species inhabiting the Barents Sea display great seasonal and inter-annual variation in abundance and distribution. This study describes the assemblages and distributions of fish species in the southwestern and central part of the Barents Sea, which includes the polar front. The area has an unpredictable environment due to variable inflow

1998
This chapter addresses empirical facts about structure of local freshwater fish assemblages. The evolutionary (ultimate) or mechanistic (proximate, ecological) explanations for that structure are the focus of later chapters. In Chapter 1, I defined a local “assemblage” as the fishes that would be found together in one particular place or “locality ...

Overview of Fishes and Fish Assemblages
1998The mass of women and men who study ecology of fishes do indeed “lead lives of quiet desperation”—but not the world-weary despair of Thoreau. Most, like Reighard, exist in a state of chronic tension between deep satisfaction with their work and frustration from the fact that fishes are so complex that no individual can understand all that could be ...

Fish Assemblage Recovery Along a Riverine Disturbance Gradient
Ecological Applications, 1993Artificial fluctuations in streamflow have been documented to alter the composition and structure of stream communities. This study tests the hypothesis that a spatial recovery gradient in fish assemblage structure exists downstream of a hydroelectric dam, and that recovery can be identified by the presence and abundance of species largely restricted ...

Effects of habitat modification on coastal fish assemblages
Journal of Fish Biology, 2010The purpose of this study was to assess the influence of anthropogenic modification of coastal habitats on fish assemblages in Taiwan, comparing the abundance, species richness and taxonomic composition of fishes on natural v. artificial habitats.

Microhabitat use in a mediterranean riverine fish assemblage
Oecologia, 1987Over a 22 month period Barbus graellsii, Chondrostoma toxostoma, Cyprinus carpio, Esox lucius, Gobio gobio, and Leuciscus cephalus displayed non-random microhabitat use in the Rio Mattarraña, Spain and generally were overrepresented in deep microhabitats with low or undetectable flow velocities.
