Mixed-function oxygenases, oxidative stress, and chromosomal damage measured in lesser scaup wintering on the Indiana Harbor Canal Mixed-function oxygenases, oxidative stress, and chromosomal damage measured in lesser scaup wintering on the Indiana Harbor Canal
During the winter of 1993-1994, male lesser scaup (Aythya alfinis) were collected on the heavily polluted Indiana Harbor Canal, East Chicago, Indiana, and examined for several bioindicators of chemical exposure. Livers were analyzed for activities of three cytochrome P450-associated monooxygenases and four measures of oxidative stress. Blood and spleen were analyzed by flow cytometry for

Energetic dose: Beyond fire and flint? Energetic dose: Beyond fire and flint?
Nutritional and bioenergetic interactions influence exposure to environmental chemicals and may affect the risk realized when wildlife are exposed in the field. Here, food-chain analysis focuses on prairie voles (Microtus ochrogaster) and the evaluation of chemical risks associated with paraquat following 10-d dietary exposures. Reproductive effects were measured in 60-d trials that...

Heron conservation Heron conservation
Herons are large, popular and, in many cases, spectacular birds found in wetlands world-wide, both tropical and temperate, natural and man-made. Some populations are very small and localized, some have decreased, some have expanded their ranges, and a few are pests of human activities. In the fifteen years since the publication of the latest monographic treatment of the family, The...

Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Robbins Nest, Laurel, MD (390-0765) Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Robbins Nest, Laurel, MD (390-0765)
This is the first of three stations along the Patuxent River. Elevation here at the edge of the Piedmont ranges from 265 ft at the house to 160 ft at the river. In spite of easterly winds and heavily overcast skies from Hurricanes Dennis, Floyd, and Irene, we suffered from drought all summer, not rain. We had only about two inches each in June and July, 4.55 in August, then a whopping 16...

Estimation of contributions to population growth: A reverse-time capture-recapture approach Estimation of contributions to population growth: A reverse-time capture-recapture approach
We consider methods for estimating the relative contributions of different demographic components, and their associated vital rates, to population growth. We identify components of the population at time i (including a component for animals not in the population at i). For each such component we ask the following question: “What is the probability that an individual randomly selected...

Ecotoxicology of organic contaminants to amphibians Ecotoxicology of organic contaminants to amphibians
The effects of organic contaminants on amphibians are poorly known but of considerable interest. These contaminants include the highly toxic dioxins and furans as well as PCBs, PAHs and organochlorine pesticides. Although these compounds may have lower acute toxicity than dioxins and furans, they have been implicated in several problems associated with genotoxicity, endocrine disruption

Approaches for assessment of terrestrial vertebrate responses to contaminants: moving beyond individual organisms Approaches for assessment of terrestrial vertebrate responses to contaminants: moving beyond individual organisms
Conclusions: A need for a broader range ofinformation on effects of contaminants on individuals exists among the 4 classes of terrestrial vertebrates, especially mammals, reptiles, and amphibians. Separation of contaminant effects from other effects and reduction of speculative extrapolation within and among species requires information that can be produced only by combined field and...

Effects of Altosid and Abate-4E on deformities and survival in southern leopard frogs under semi-natural conditions Effects of Altosid and Abate-4E on deformities and survival in southern leopard frogs under semi-natural conditions
Experimental wetlands were sprayed with Abate-4E (a.i. temephos) and Altosid (a.i. methoprene) through the summer following label directions. In late August and early Septemeber metamorphing tadpoles were captured and examined for deformities. Tadpoles captured from ponds sprayed with Altosid had a 15% deformity rate mostly involving total or partially missing hind limbs. Tadpoles from...
