Main and interactive effects of arsenic and selenium on mallard reproduction and duckling growth and survival
T.R. Stanley Jr., J. W. Spann, G. J. Smith, R. Rosscoe
1994, Archives of Environmental Contamination and Toxicology (26) 444-451
Arsenic (As) and selenium (Se) occur together in high concentrations in the environment and can accumulate in aquatic plants and invertebrates consumed by waterfowl. Ninety-nine pairs of breeding mallards (Anas platyrhynchos) were fed diets supplemented with As (sodium arsenate) at 0, 25, 100, or 400 μg/g, in combination with Se...
Sources of variation in loss rates of color bands applied to adult roseate terns (Sterna dougallii) in the western North Atlantic

1994, The Auk (111) 881-887
A model-based analysis was done to test several hypotheses concerning the rates of loss of butt-ended color bands placed on adult Roseate Terns (Sterna dougallii) in the western North Atlantic. These birds were captured and color banded from 1987-1991 at four colony sites, and recaptured from 1989-1992 as part of...

Falkner Island, a two hectare unit of the Stewart B. McKinney National Wildlife Refuge, is located at 41°13'N, 72°39'W in Long Island Sound about 5 km south of Guilford, Connecticut. This island, described in detail by Helander (1988), is the nesting site of a mixed colony of several thousand Common...

Carbofuran affects wildlife on Virginia corn fields
E.R. Stinson, L.E. Hayes, P.B. Bush, Donald H. White
1994, Wildlife Society Bulletin (22) 566-575
Forty-four Virginia corn fields on 11 farms were searched for evidence of dead or debilitated wildlife following in-furrow application of granular carbofuran (Furadan 15G) during April and May 1991. Evidence of pesticide poisoned wildlife, including dead animals, debilitated animals, feather spots, and fur spots was found on 33 fields...
Two hybrid common x roseate terns fledge at Falkner Island, Connecticut
James M. Zingo, Christopher A. Church, Jeffrey A. Spendelow
1994, The Connecticut Warbler (14) 50-55
Although these two similarly-sized species are sympatric throughout much of their breeding range, there are few published records of hybridization between Roseate (Sterna dougallii) and Common (S. hirundo) Terns. Records include at least five from Europe (Witherby and Ticehurst 1908, Perry 1972, Robbins 1974, Burggraeve 1977, van den Berg 1980)...
Conservation reserve program: benefit for grassland birds in the northern plains

1994, Transactions of the North American Wildlife and Natural Resources Conference (59) 328-336
During the past few decades numbers of some species of upland-nesting birds in North America have declined. Duck species such as mallard (Anas platyrhynchos), northern pintail (A. acuta) and blue-winged teal (A. discors) have declined since the early 1970s and have remained low since 1985 (Caithamer et al. 1993). Some...
Puerto Rican parrots and potential limitations of the metapopulation approach to species conservation

1994, Conservation Biology (8) 114-123
Population viability analyses for a number of endangered species have incorporated a metapopulation approach. The risk assessments of these viability analyses have indicated that some extant populations should be subdivided into numerous subgroups with exchange of individuals among them in order to reduce the chance of catastrophic loss of the...
Estimating breeding proportions and testing hypotheses about costs of reproduction with capture-recapture data
James D. Nichols, James E. Hines, Kenneth H. Pollock, Robert L. Hinz, William A. Link
1994, Ecology (75) 2052-2065
The proportion of animals in a population that breeds is an important determinant of population growth rate. Usual estimates of this quantity from field sampling data assume that the probability of appearing in the capture or count statistic is the same for animals that do and do not breed. A...

The applicability of terrestrial visitor impact management strategies to the protection of coral reefs
J. L. Marion, C.S. Rogers
1994, Ocean and Coastal Management (22) 153-163
A dramatic expansion in nature-based tourism to tropical coastal destinations has occurred in the past 20 years. Tourism development, combined with intense recreational pressures, has irreversibly transformed and degraded many popular scenic natural environments. This paper examines the management of recreational impacts to coral reefs using Virgin Islands National Park...
The earthquake prediction experiment at Parkfield, California

1994, Reviews of Geophysics (32) 315-336
Since 1985, a focused earthquake prediction experiment has been in progress along the San Andreas fault near the town of Parkfield in central California. Parkfield has experienced six moderate earthquakes since 1857 at average intervals of 22 years, the most recent a magnitude 6 event in 1966. The probability of...

Famphur (phosphorothioic acid, O,(4((dimethylamino)sulfonyl),phenoyl)O,Odimethyl ester), also known as Warbex, is a systemic organophosphorus insecticide used almost exclusively as a veterinary chemical to control parasite in livestock. Only famphur and its oxygen analog, famoxon, were of toxicological significance; other famphur metabolites were 31 to 237 times less toxic,...

We determined the current range of the desert tortoise (Gopherus agassizii) based on the available latest data from government agencies, the literature, and our experience. We developed the first detailed range map of this species and summarized information about habitat preferences. New records of occurrences were incorporated, and some peripheral...

1994, Atoll Research Bulletin No. 398.
conclusion: Lushly wooded Caroline Atoll, with the majority of its 39 islets (399 ha of land) either in near-pristine condition or having recovered remarkably from past disturbance, is one of the least spoiled atolls in the Pacific. Uninhabited, it harbors plant ecosystems and breeding seabirds (Pt. II) of...
