Specimens and probable breeding activity of the band-rumped storm-petrel on Hawaii
W.E. Banko, P.C. Banko, R.E. David
1991, The Wilson Bulletin (103) 650-655
Specimens (a downy fledgling and a hatch-year juvenile) and nocturnal calling of the Band-rumped Storm-Petrel (Oceanodroma custro) are evidence that this rare seabird breeds on the island of Hawaii. Nocturnal calling over land and sightings near the coast indicate that populations nest on the southwest rift and possibly the upper...
Mammal mortality at Arizona, California, and Nevada gold mines using cyanide extraction
D. R. Clark Jr., R. L. Hothem
1991, California Fish and Game (77) 61-69
Five-hundred nineteen mammals were reported dead at cyanide-extraction gold mines in Arizona [USA], California, and Nevada from 1984 through 1989. Most numerous were rodents (34.9%) and bats (33.7%); 'bat' was the most often reported category among 24 species or species groups. There are an estimated 160 cyanide-extraction gold mines in...
Reproductive vulnerability: Parental attendance around hatching in roseate (Sterna dougallii) and common (S. hirundo) terns
J. Burger, M. Gochfeld
1991, Condor (93) 125-129
Presence of one or both members of a pair at the nest site during the incubation and early chick stage reduces reproductive losses due to predation and weather stresses. The authors monitored the presence of pair members by the temporary removal of one member of several pairs of Roseate (Sterna...

Bird population and habitat surveys in urban areas
R.M. DeGraaf, A. D. Geis, P.A. Healy
1991, Landscape and Urban Planning (21) 181-188
Breeding bird populations in six habitats in Columbia. MD, were studied to develop procedures suitable for measuring bird use of residential areas and to identify habitat characteristics that define the distribution of various common bird species. A procedure to measure bird use based on 4-min transect counts on plots...
Effects of submersed macrophytes on dissolved oxygen, pH and temperature under different conditions of wind, tide and bed structure
V. Carter, N. B. Rybicki, R.S. Hammerschlag
1991, Journal of Freshwater Ecology (6) 121-133
Seasonal data on diurnal dissolved-oxygen concentration (DO), pH, temperature and chlorophyll-a were collected and species composition and vertical structure of macrophyte beds were analyzed in the tidal Potomac River during the 1987 growing season. The relationships among these variables and physical and climatic factors were analyzed. Elevated surface temperatures, DO...

Trends in North American small mammals found in common barn-owl (Tyto alba) dietary studies
D. R. Clark Jr., C.M. Bunck
1991, Canadian Journal of Zoology (69) 3093-3102
Data on mammals were compiled from published studies of common barn-owl (Tyto alba) pellets. Mammalian composition of pellet samples was analyzed within geographic regions in regard to year, mean annual precipitation, latitude, and number of individual mammals in the sample. Percentages of individuals in pellets that were shrews...

Environmental contaminants in bald eagle eggs
Stanley N. Wiemeyer, C.M. Bunck, C. J. Stafford
1991, Journal of Raptor Research (25) 162 (abs)
Bald Eagle eggs (1968-84) were analyzed for organochlorine pesticides, PCBs and mercury. DDE declined in WI, ME and the Chesapeake Bay. DDE was most closely related to shell thickness and reproduction at sampled breeding areas. Sixteen ppm DDE (wet weight) was associated with 15% shell thinning. Reproduction was normal...

Conservation genetics of the endangered Isle Royale gray wolf

1991, Conservation Biology (5) 41-51
The small group of wolves on Isle Royale has been studied for over three decades as a model of the relationship between large carnivores and their prey. During the last ten years the population declined from 50 individuals to as few as 12 individuals. The causes of this decline may...

Conservation of the yellow-shouldered blackbird Agelaius xanthomus, an endagered West Indian species
J. W. Wiley, W. Post, A. Cruz
1991, Biological Conservation (55) 119-138
The yellow-shouldered blackbird Agelaius xanthomus, endemic to Puerto Rico and Mona Island, is endangered, mainly because of brood parasitism by the shiny cowbird Molothrus bonariensis, which reached Puerto Rico at least 30 years ago. The yellow-shouldered blackbird populations have since declined, about 770–1200 remaining (470–900 on Mona Island) by 1982–1986 compared to...
Acute toxicity of four anticholinesterase insecticides to American kestrels, eastern screech-owls and northern bobwhites
Stanley N. Wiemeyer, D. W. Sparling
1991, Environmental Toxicology and Chemistry (10) 1139-1148
American kestrels (Falco sparverius), eastern screech-owls (Otus asio), and northern bobwhites (Colinus virginianus) were given single acute oral doses of four widely diverse anticholinesterase pesticides: EPN, fenthion, carbofuran, and monocrotophos. LD50s, based on birds that died within 5 d of dosage, were computed for each chemical in each species. Sex...

This volume is a rather odd contribution, a hybrid between an academic work and a popular book, and both suffers and benefits from these attributes. The 18 chapters are divided into four parts that deal with the environment and humans (3 chapters and ca. 12% of the text), comparative biology...

A vacuum-operated pore-water extractor for estuarine and freshwater sediments
Parley V. Winger, Peter J. Lasier
1991, Archives of Environmental Contamination and Toxicology (21) 321-324
A vacuum-operated pore-water extractor for estuarine and freshwater sediments was developed and constructed from a fused-glass air stone attached with aquarium airline tubing to a 30 or 60 cc polypropylene syringe. Pore water is extracted by inserting the air stone into the sediment and creating a vacuum by retracting and...
Point counts from clustered populations: Lessons from an experiment with Hawaiian crows
G.D. Hayward, C. B. Kepler, J. M. Scott
1991, Condor (93) 676-682
We designed an experiment to identify factors contributing most to error in counts of Hawaiian Crow or Alala (Corvus hawaiiensis) groups that are detected aurally. Seven observers failed to detect calling Alala on 197 of 361 3-min point counts on four transects extending from cages with captive Alala. A detection...
