Wood frogs (Rana sylvatica) were exposed to aluminum (Al; 10, 100, 500, 1000, or 2000 μgL(-1)) or copper (Cu; 1, 10, 50, 100, 200 μgL(-1)) at a pH of 4.70 from the beginning of the larval period through the completion of metamorphosis (range=43-102

Although metabolic rate is considered to be useful as a general indicator of the biological effects of exposure to metals, it is seldom measured in conjunction with specific physiological, biochemical or cellular parameters. The purpose of this inves

The influence of exposure time on gill Na+/K+ ATPase activity and metabolic rate in populations of fathead minnows (Pimephales promelas) and golden shiners (Notemigonus crysoleucas) hatcheries in Ohio (OH) and Pennsylvania (PA) when exposed to sublet

Understanding the effects of chemical toxicants on energetic processes is an important aspect of ecotoxicology. However, the influence of toxicant concentration and time of exposure on metabolism in aquatic organisms is still poorly understood. The p

Mercury concentrations in largemouth bass (Micropterus salmoides) bass were compared among five reservoirs in South Carolina. Three of these reservoirs (Lake Russell, Lake Thurmond, and Lake Marion) are accessible to the public and two (L-Lake and Pa

Small mammals can be regarded as excellent subjects to test suppositions about population growth migration and reproduction, and, in particular, on how the complex physical structure of the environment affects the ecology of populations and communiti

Short-term changes in testicular spermatozoa, testes weight, testes length, epididymes weight, epididymal spermatozoa, and body weight of adult and yearling male white-tailed deerOdocoileus virginianus (Zimmermann, 1780) were examined over a 9-week p

The genetic structure of earthworm (Lumbricus rubellus) populations from plots (N=3) contaminated by sewage sludge (containing Cd, Cu, Pb, Zn) and reference plots (N=3) was compared. Earthworms (N=30–40 per plot) were collected during May 2000 and

Many of the modern concepts used in ecotoxicology have historical roots in earlier thinking from the field of radioecology. An example is the concept of Monitored Natural Attenuation (MNA), which is an approach to the remediation of contaminated wast
