Using previously published atlas data for 122 mixed-species wading bird colonies on islands along the Atlantic coast (Maine to Florida, 1976-77), we examined relationships between population sizes of 11 species of egrets, herons, ibises, and wood storks (Mycteria americana) and nine habitat variables. On nautical charts, we measured four island...

1987, Book chapter, Collected Reports from the Czechoslovak-American Symposium on Toxic Effects of Chemical Environmental Contaminants upon Production and Reproduction Ability in Free-Living Animals (held October 3-4, 1983).
Acidic deposition occurs over most of the United States and the deposition patterns and theoretical vulnerabilities of aquatic ecosystems to chemical changes can be delineated, but few data exist on concomitant biological effects. Hypothetical direct effects are limited primarily to toxicity of various heavy metals mobilized at reduced...

Various species of kestrels have become important bioindicators of environmental quality and test species for comparative toxicology in captivity. At least 7 species of kestrels have been used to document the presence of environmental contamination primarily organochlorines and metals, in at least 15 countries. Captive kestrels have been...

Little is known of the incidence and pathogenic effects of infectious and parasitic diseases in the world's 15 crane species. in addition to being a primary cause of crane morality, diseases increase the susceptibility of an animal to depredation, malnutrition, accidents, and other mortality factors and reduces its chances of...

1987, Book chapter, The Ancestral Kestrel: Proceedings of a Symposium on Kestrel Species, St. Louis, Missouri, December 1st, 1983
A 15-year summary of the BBS data suggests that continental numbers of American Kestrels have increased during 1966-1979. According to analyses of physiographic and state/province strata, some areas are largely responsible for the increase in the U.S. and southern Canada and that only in Illinois and Arkansas have kestrels declined....
Arkansas black bear hunter survey

Questionnaires were mailed to black bear (Ursus americanus) hunters in Arkansas following the 1980-84 bear seasons to determine participation, hunter success, and number of bears observed by hunters. Man-days of hunting to harvest a bear ranged from 148 to 671 and hunter success ranged from 0.4% to 2.2%. With the...

The phytoplankton component of seston in San Francisco Bay
S.M. Wienke, J. E. Cloern
1987, Netherlands Journal of Sea Research (21) 25-33
Phytoplankton biomass (as carbon) was estimated from chlorophyll a concentrations (Chla) and a mean value for the ratio of phytoplankton carbon to chlorophyll a in San Francisco Bay. The ratio was determined as the slope of a Model II regression of POC' against (Chla), where POC' is total particulate organic carbon minus sediment-associated non-phytoplankton...
North American nonmarine climates and vegetation during the Late Cretaceous

1987, Palaeogeography, Palaeoclimatology, Palaeoecology (61) 33-77
Analyses of physiognomy of Late Cretaceous leaf assemblages and of structural adaptations of Late Cretaceous dicotyledonous woods indicate that megathermal vegetation was an open-canopy, broad-leaved evergreen woodland that existed under low to moderate amounts of rainfall evenly distributed through the year, with a moderate increase at about 40–45°N. Many dicotyledons...
