Glenn H. Olsen, M.J. Turell, B.B. Pagac
1997, Journal of Wildlife Diseases (33) 312-315
An epizootic of eastern equine encephalitis (EEE) at the Patuxent Wildlife Research Center (PWRC), Laurel, Maryland (USA), in 1989 provided an opportunity to determine if EEE immunization protected whooping cranes (Grus americana). Based on seroconversion of 31% of sympatric hatch-year sandhill cranes, Grus canadensis,...

Capture-recapture analysis of a wintering black-capped chickadee population in Connecticut, 1958-1993
G. Loery, James D. Nichols, James E. Hines
1997, The Auk (114) 431-442
We investigated the dynamics of a wintering population of Black-capped Chickadees (Parus atricapillus) using data from a long-term capture-recapture study. Goodness-of-fit and likelihood-ratio tests indicated that the standard Jolly-Seber model was inadequate for the data, so we explored different parameterizations of a model in which survival probability for new captures...

Development of an IBI-based assessment of depressional wetlands in Maryland and Delaware
D. W. Sparling, Michael Keller, T. P. Lowe, M. Perry, B. Teels, L. Brown, L. Mazanti, N. Melvin
1997, Book chapter, The Future of Wetland Assessment: Applying science through the hydrogeomorphic assessment approach and other approaches. Abstracts of a meeting held March 10-13, 1997, Parole, Maryland.
The hydrogeomorphic approach (HGM) of wetland assessment emphasizes functional components of wetlands such as water storage, transformation and cycling of elements, accumulation of sediments, and preservation of habitats. Many of the elements measured in HGM are physical rather than ecological or biological. The HGM approach, therefore, provides information on...

Effective number of breeding adults in Bufo bufo estimated from age-specific variation at minisatellite loci
K.T. Scribner, J.W. Arntzen, T. Burke
1997, Molecular Ecology (6) 701-712
Estimates of the effective number of breeding adults were derived for three semi-isolated populations of the common toad Bufo bufo based on temporal (i.e. adult-progeny) variance in allele frequency for three highly polymorphic minisatellite loci. Estimates of spatial variance in allele frequency among populations and of age-specific measures of genetic variability are...
