Olga Herrera-MacBryde, Francisco Dallmeier, Bruce MacBryde, James A. Cominskey, Carmen Miranda, editor(s)
2000, Book chapter, Biodiversity, Conservation and Management in the Region of the Beni Biological Station Biosphere Reserve, Bolivia
Previous collections in the Departamento del Beni in tropical Bolivia only hinted at high levels of herpetological biodiversity (Fugler 1986, 1988; de la Riva 1990a; Fugler and de la Riva 1990). Fieldwork (totaling 48 days) in July-August 1988 and September 1987 (dry seasons) and November-December 1990 (wet season) has...
Effects of Altosid and Abate-4E on deformities and survival in southern leopard frogs under semi-natural conditions
D. W. Sparling
Hinrich Kaiser, Gary S. Casper, Neil P. Bernstein, editor(s)
2000, Book chapter, Investigating Amphibian Declines: Proceedings of the 1998 Declining Amphibians Conference
Experimental wetlands were sprayed with Abate-4E (a.i. temephos) and Altosid (a.i. methoprene) through the summer following label directions. In late August and early Septemeber metamorphing tadpoles were captured and examined for deformities. Tadpoles captured from ponds sprayed with Altosid had a 15% deformity rate mostly involving total...

2000, Book chapter, Ecology and Management of Cowbirds and Their Hosts: Studies in the Conservation of North American Passerine Birds
During 1988-1993, we monitored nests of neotropical migrant birds in seven suburban Maryland forests to compare parasitism and predation rates in forests of different areas. Of 1,122 nests monitored, 672 were of Wood Thrush, the most commonly found nesting species. Study sites were forests that ranged in size...
Establishment of warm season grasses with and without the use of compost soil amendments
Matthew C. Perry, P.C. Osenton, G.A. Gough, E.J.R. Lohnes
2000, Book chapter, Proceedings of the Second Eastern Native Grass Symposium held in Baltimore, Maryland, November 17-19
Two compost materials (COMPRO and LEAFGRO) were evaluated as soil amendments to enhance wildlife habitats, while maintaining optimal floral and faunal biodiversity. Special emphasis was placed on the role of compost in the establishment and retention of native warm season grasses (Andropogon gerardi, Schizachyrium scoparium, and Sorghastrum nutans)....

Host selection in the forest interior: cowbirds target ground-nesting species
D.C. Hahn, Jeff S. Hatfield
2000, Book chapter, Ecology and Management of Cowbirds and their Hosts: Studies in the Conservation of North American Passerine Birds
We investigated patterns of cowbird host selection in a large (1300 ha), unfragmented forest in eastern New York in 1992-3 to determine whether cowbird parasitism rates can be attributed to species-specific traits or to other features associated with nest sites. Nest height was significantly associated with parasitism (P =...
Monitoring is not enough: on the need for a model-based approach to migratory bird management
J.D. Nichols
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Informed management requires information about system state and about effects of potential management actions on system state. Population monitoring can provide the needed information about system state, as well as information that can be used to investigate effects of management actions. Three methods for investigating effects of management...
Development of management objectives for breeding birds in the Mississippi Alluvial Valley
A.J. Mueller, D.J. Twedt, C.R. Loesch
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
We used a six-step process to set habitat objectives and population goals for breeding birds in the Mississippi Alluvial Valley. Specifically, we used existing empirical studies and mathematically derived viable population estimates to define habitat objectives and population goals for bottomland hardwood forest, the most important habitat type in...
Managing wetlands for waterbirds: How managers can make a difference in improving habitat to support a North American Bird Conservation Plan
R.M. Erwin, M.K. Laubhan, J.E. Cornely, D.M. Bradshaw

2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Wetlands are the most productive ecosystems in the world, yet they have suffered more loss and degradation than any other ecosystem. Not surprisingly, 50% (29 of 58) of all the bird species in the U. S. (excluding Hawaii and territories) that are listed either as federally threatened or endangered,...

2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Urban and suburban habitats often contain a variety of Neotropical migratory birds, but are poorly sampled by programs such as the North American Breeding Bird Survey. DC Birdscape was developed to inventory and monitor birds in Washington, D.C. Birds were surveyed using a systematic sample of point counts...
Population and habitat assessment: Monitoring bird populations over large areas: Introduction
J.R. Sauer, R.J. Cooper
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Monitoring provides essential information about status and change in bird populations. For Neotropical Migrant Birds (NTMBs), the North American Breeding Bird Survey (BBS) has been particularly influential in documenting regional population change and often is cited as justification for management actions. However, as with most bird surveys, the...
Conservation planning and monitoring avian habitat
D.J. Twedt, C.R. Loesch
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Migratory bird conservation plans should not only develop population goals, they also should establish attainable objectives for optimizing avian habitats. Meeting population goals is of paramount importance, but progress toward established habitat objectives can generally be monitored more easily than can progress toward population goals. Additionally, local or...
Estimating survival of neotropical-nearctic migratory birds: Are they dead or just dispersed?
M.R. Marshall, R.R. Wilson, R.J. Cooper
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
The most common method for estimating adult survival in site specific demographic studies of Neotropical-Nearctic migratory bird populations is by measuring the return rate of marked individuals. Return rate historically has been defined as the ratio of resighted birds to the total number banded (i.e., with bands on) the prior...

Matthew C. Perry, P. Kangas, H.H. Obrecht III
Francisco A. Comin, Jorge A. Herrera-Silveira, Javier Ramirez-Ramirez, editor(s)
2000, Book chapter, Limnology and aquatic birds, monitoring, modelling and management: Second International Symposium on Limnology and Aquatic Birds, Monitoring, Modelling and Management, Merida, Yucatan, Mexico, November 24-27, 1997
Patuxent Research Refuge, located in Central Maryland (USA), has approximately 140 ha of impoundments that were constructed for recreational and wildlife conservation purposes. Impoundments are of three major designs: dammed ravines, excavated basins, and diked ponds. Over 50 species of wetland plants were transplanted to impoundments of Patuxent...
Effects of two long-term mowing regimes on vegetation
Matthew C. Perry, A.S. Deller
2000, Book chapter, Proceedings of the Second Eastern Native Grass Symposium held in Baltimore, Maryland, November 17-19, 1999
Wildlife managers have for many years been interested in the role of mowing as a management technique to benefit wildlife. Two long-term mowing regimes (60 years of similar management) were evaluated at Patuxent Research Refuge during the summer of 1997 to better understand the influence of mowing on vegetation...
Grassland birds: An overview of threats and recommended management strategies
P.D. Vickery, J.R. Herkert, F.L. Knopf, J. Ruth, C.E. Keller
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
Grassland ecosystems are dependent on periodic disturbance for habitat maintenance. Historically, grazing by native herbivores and prairie fires were the agents principally responsible for maintaining grassland areas. However, elimination of native herbivores, wide-spread fire suppression, and conversion for agriculture have greatly altered grasslands in the United States and Canada....

Combining information from monitoring programs: Complications associated with indices and geographic scale
J.R. Sauer
Rick Bonney, David N. Pashley, Robert Cooper, Larry Niles, editor(s)
2000, Book chapter, Strategies for Bird Conservation: The Partners in Flight Planning Process. Proceedings of the 3rd Partners in Flight Workshop, Cape May, New Jersey, October 1-5, 1995
To adequately monitor Neotropical migratory birds, information must be collected to assess population change at local, regional, and continent-wide scales. I suggest that large-scale survey results (such as those derived from the North American Breeding Bird Survey) should not be used to predict population attributes on parks, refuges, and...
