Mathematical models have been widely applied to perform chemical risk assessments on biological populations for a variety of ecotoxicological pro- cesses. In this paper, by introducing a dose-dependent mortality rate function, we formulate a toxin-dependent aquatic population model that...

Many autecological effects of temperature on fish are known, and fishery biologists have begun to incorporate this knowledge into population-level relations that can be used to assess possible effects of climatic warming on fishes and their habitats. However, the problem of extrapolating these or...

Mosasaurs (family Mosasauridae) are a diverse group of secondarily aquatic lizards that radiated into marine environments during the Late Cretaceous (98–65 million years ago). For the most part, they have been considered to be simple anguilliform swimmers – i.e., their propulsive force was...

Density-Dependent Effects and the Regulation of Crucian Carp Populations in Single-Species Ponds
Download1994
Tonn, W. M., Holopainen, I. J., Paszkowski, C. A.
Crucian carp (Carassius carassius) is often the only fish species present in small ponds of northern Europe. Such populations are typically at high densities and consist primarily of small, relatively slender, and short-lived fish; populations in multispecies assemblages in lakes display opposite...

Enhancing productive capacity in the Canadian Arctic: Assessing the effectiveness of instream habitat structures in habitat compensation
Download2004
We examined the effectiveness of physical habitat structures (ramps, V-weirs, vanes, and groins) at increasing the productive capacity of a newly created 3.4-km artificial stream in the Barrenlands region of the Northwest Territories, Canada. We quantified changes in fish density and growth in...
