Comparison of helicopter and ground surveys of waterfowl broods in southern Ontario
T.S. Gabor, J. R. Longcore, H.R. Murkin, A.N. Arnason
2000, Northeast Wildlife (55) 11-19
Managers often employ aerial survey information to manage waterfowl. Results of surveys by helicopter and from elevated platforms were compared to determine the accuracy of helicopters to detect waterfowl broods on beaver ponds in southern Ontario in 1996 and 1997. Fewer broods were detected from the helicopter than...
[Book review] Ecological Scale - Theory and Applications by D.L. Peterson and V. Thomas Parker, editors
A.F. O'Connell Jr.
2000, Park Science (20) 4-5,
Covering the complexity of the scale topic, this volume represents an important compilation of information on a topic that is often misunderstood, and one for which little attention is paid (although, thankfully, this seems to be on the decline). Although technical, this book provides full exposure to the scale...

GIS interpolations of witness tree records (1839-1866) for northern Wisconsin at multiple scales
H.S. He, D.J. Mladenoff, T.A. Sickley, G.R. Guntenspergen
2000, Journal of Biogeography (27) 1031-1042
To construct forest landscape of pre-European settlement periods, we developed a GIS interpolation approach to convert witness tree records of the U.S. General Land Office (GLO) survey from point to polygon data, which better described continuously distributed vegetation. The witness tree records (1839-1866) were processed for a 3-million ha landscape...
Estimating forest crown area removed by selection cutting: a linked regression-GIS approach based on stump diameters
S.C. Anderson, J.A. Kupfer, R.R. Wilson, R.J. Cooper
2000, Forest Ecology and Management (137) 171-177
The purpose of this research was to develop a model that could be used to provide a spatial representation of uneven-aged silvicultural treatments on forest crown area. We began by developing species-specific linear regression equations relating tree DBH to crown area for eight bottomland tree species at White River National...

Evaluating immunocontraception for managing suburban white-tailed deer in Irondequoit, New York
B.A. Rudolph, W.F. Porter, H.B. Underwood
2000, Journal of Wildlife Management (64) 463-473
Immunocontraception is frequently proposed as an alternative to lethal removal of females for deer management. However, little information is available for evaluating the potential of applying immunocontraceptives to free-ranging populations. Our objectives were to estimate effort required to apply porcine zona pellucida (PZP) to individual deer and assess the utility...
Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Patuxent powerline right-of-way (390-0764)
Deanna K. Dawson
2000, North American Bird Bander (25) 63-63
Fall 1999 was among the poorest seasons in this banding station's 20 years of operation. Record high capture totals were set for only two species: Ruby-throated Hummingbird (41 individuals captured, none banded; previous high 21) and White-breasted Nuthatch (two individuals banded; previous high, one). The only other species that stood...

Inferences about nested subsets structure when not all species are detected
E. Cam, J.D. Nichols, J.E. Hines, J.R. Sauer
2000, Oikos (91) 428-434
Comparisons of species composition among ecological communities of different size have often provided evidence that the species in communities with lower species richness form nested subsets of the species in larger communities. In the vast majority of studies, the question of nested subsets has been addressed using information on...
Survival and reproductive biology of the Bachman's Sparrow
J.M. Stober, D.G. Krementz
2000, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (54) 383-390
We estimated breeding season survival rates and nest success for Bachman's Sparrows at the Savannah River Site, South Carolina, using radio telemetry. The 1995 breeding season (2 May-9 Aug) survival rate was 0.905 (95% C. I. 0.779-1.03) with 2 mortalities out of 20 individuals. The 1996 breeding season...
Consideraciones para la estimacion de abundancia de poblaciones de mamiferos. [Considerations for the estimation of abundance of mammal populations.]
R.S. Walker, A.J. Novare, J.D. Nichols
2000, Mastozoologia Neotropical / Journal of Neotropical Mammalogy (7) 73-80
Estimation of abundance of mammal populations is essential for monitoring programs and for many ecological investigations. The first step for any study of variation in mammal abundance over space or time is to define the objectives of the study and how and why abundance data are to be used....
Movements and survival of Bachman's Sparrows in response to prescribed summer burns in South Carolina
B.D. Seaman, D.G. Krementz
2000, Proceedings of the Annual Conference of the Southeastern Association of Fish and Wildlife Agencies (54) 227-240
Prescribed winter burning is a common practice in longleaf pine (Pinus palustris) to manage for red-cockaded woodpeckers (Picoides borealis). The effect of these burns on non-target animals is not well studied. Bachman's sparrows (Aimophila aestivalis) were captured in predominantly longleaf pine stands to be burned and not to...
Breeding season demography and movements of Eastern Towhees at the Savannah River Site, South Carolina
David G. Krementz, Larkin A. Powell
2000, The Wilson Bulletin (112) 243-248
The Eastern Towhee (Pipilo erythrophthalmus) has undergone population declines across much of its range, especially in New England. Despite being a widespread and, at one time, a common species, relatively little is known about its natural history, ecology, or demographics. We conducted baseline research on Eastern Towhees at...

Chandler S. Robbins
2000, North American Bird Bander (25) 63-63
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...

In a slight reorganization, the Mount Nebo station in the mountains of western Maryland near Oakland was moved to Region III (Western Ridge), in exchange for Lakeshore Estates in Leon County, Florida, which we welcome to Region IV. This was the year of the hurricane in Region IV, with the...
The 1995-1999 Summary of the North American Breeding Bird Survey
K.L. Pardieck, J.R. Sauer
2000, Bird Populations (5) 30-48
Data from the North American Breeding Bird Survey were used to estimate continental and regional changes in bird populations for the 5-yr period 1995-1999 and the 2-yr period 1998-1999. These short-term changes were placed in the context of population trends estimated over the 1966-1999 interval. During 1995-1999, 44%...
Estimation of contributions to population growth: A reverse-time capture-recapture approach
J.D. Nichols, J.E. Hines, J.D. Lebreton, R. Pradel
2000, Ecology (81) 3362-3376
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...
A new species of Hyla (Anura: Hylidae) from the Sierra Mixes, Oaxaca, Mexico, with comments on ontogenetic variation in the tadpoles
P.C. Ustach, J.R. Mendelson III, R.W. McDiarmid, J. A. Campbell
2000, Herpetologica (56) 239-250
We describe a new species of Hyla that differs from the similar-loohng species H. pentheter by reaching a larger size, ha\iing a smaller tympanum, more webbing on the feet, more extensive nuptial excrescences, and a different color pattern on the flanks. \Ve tentatively place this new species in the...
The AOU Conservation Committee Review of the biology, status, and management of Cape Sable Seaside Sparrows: Final report

2000, The Auk (117) 1093-1115
The Cape Sable Seaside Sparrow (Ammodramus maritimus mirabilis) was listed as an original member of the federal list of endangered species in 1968. It is restricted to seasonally flooded prairies of extreme southern Florida and is disjunct from all other conspecific breeding populations (Kushlan et al 1982, McDonald 1988). Since...
