Our study of brood parasitism patterns in forest communities revealed the egg-laying frequency and host selection patterns of female cowbirds. By integrating molecular genetics and spatial data, we have the first published estimate on cowbird laying rates in field studies. The 29 females in the study laid only...

1999, Book chapter, Environmental impacts of mining activities: Emphasis on mitigation and remedial measures
Highly toxic sodium cyanide (NaCN) is used increasingly by the international mining community to extract gold and other precious metals through milling of high grade ores and heap leaching of low grade ores. Of the 98 million kg cyanide (CN) consumed in North America in 1989, about 80% was used...

To characterize risk, it is necessary to quantify the linkages and interactions between chemical, physical and biological stressors and endpoints in the conceptual framework for ecological risk assessment (ERA). This can present challenges in a multiple stressor analysis, and it will not always be possible to...
Regional analysis of population trajectories from the North American Breeding Bird Survey

The North American Breeding Bird Survey (BBS) was started in 1966, and provides information on population change and distribution for most of the birds in North America. The geographic extent of the survey, and the logistical compromises needed to survey such a large area, present many challenges for estimation...
On the importance of controlling for effort in analysis of count survey data: Modeling population change from Christmas Bird Count data

Count survey data are commonly used for estimating temporal and spatial patterns of population change. Since count surveys are not censuses, counts can be influenced by 'nuisance factors' related to the probability of detecting animals but unrelated to the actual population size. The effects of systematic changes in...
Population status of North American grassland birds from the North American Breeding Bird Survey

1999, Book chapter, Ecology and conservation of grassland birds of the western hemisphere
We summarize population trends for grassland birds from 1966 to 1996 using data from the North American Breeding Bird Survey. Collectively, grassland birds showed the smallest percentage of species that increased of any Breeding Bird Survey bird group, and population declines prevailed throughout most of North America. Although...

1999, Book chapter, Proceedings 22nd International Ornithological Congress, 16-22 August 1998, Durban.
The Alder Flycatcher Empidonax alnorum (Tyrannidae) winters from Colombia and Venezuela, south to northern Argentina. We studied the species in Manu National Park, Madre de Dios, Peru. In this area the species occupies riparian zones along lowland meander rivers as well as adjacent transition zone forest in the...

Effects of contaminants on Double-crested Cormorant reproduction in Green Bay, Wisconsin, USA

N.J. Adams, R.H. Slotow, editor(s)
1999, Book chapter, Proceedings 22nd International Ornithological Congress, 16-22 August 1998, Durban.
In 1994 and 1995, Double-crested Cormorants Phalacrocorax auritus were monitored from egg-laying through 12 days of age at Cat Island, Green Bay, Wisconsin, USA. Sample eggs at hatching were analysed for organochlorines (including total PCBs, PCB congeners, and DDE), hepatic microsomal ethoxyresorufin-O-dealkylase (EROD) activity in livers of embryos, and...
Organochlorine contaminants and Tree Swallows along the Fox River and Green Bay, Wisconsin, USA

N.J. Adams, R.H. Slotow, editor(s)
1999, Book chapter, Proceedings 22nd International Ornithological Congress, 16-22 August 1998, Durban.
Green Bay, Wisconsin is contaminated with polychlorinated biphenyls (PCBs) however, whether these contaminants affect reproduction in insectivorous birds is unknown. Tree Swallows, Tachycineta bicolor, are secondary cavity nesters that will nest in boxes and tolerate handling. Because Tree Swallows are aquatic insectivores, residues in their tissues are primarily...
Demography of forest birds in Panama: How do transients affect estimates of survival rates?
J. D. Brawn, J.R. Karr, J.D. Nichols, W.D. Robinson
N.J. Adams, R.H. Slotow, editor(s)
1999, Book chapter, Proceedings 22nd International Ornithological Congress, 16-22 August 1998, Durban.
Estimates of annual survival rates of neotropical birds have proven controversial. Traditionally, tropical birds were thought to have high survival rates for their size, but analyses of a multispecies assemblage from Panama by Karr et al. (1990) provided a counterexample to that view. One criticism of that study has...

Different processes cause patterns of shoreline change which are exhibited at different magnitudes and nested into different spatial and time scale hierarchies. The 77-km outer beach at Cape Cod National Seashore offers one of the few U.S. federally owned portions of beach to study shoreline change within the full...

1999, Report, Perspectives on the land use history of North America: A context for understanding our changing environment
Two different methods of reconstructing historical vegetation change, drawing on General Land Office (GLO) surveys and fossil pollen deposits, are demonstrated by using data from the Great Lakes region. Both types of data are incorporated into landscape-scale analyses and presented through geographic information systems. Results from the two methods reinforce...

The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, ecology, and evolutionary biology have focused enormous attention on tadpoles. Yet despite this growing interest, relatively little is known about these fascinating...
