Joshua D. Stafford, Kenneth J. Reinecke, Richard M. Kaminski, Patrick D. Gerard
2005, Journal of Environmental Management (78) 353-361
Large-scale sample surveys to estimate abundance and distribution of organisms and their habitats are increasingly important in ecological studies. Multi-stage sampling (MSS) is especially suited to large-scale surveys because of the natural clustering of resources. To illustrate an application, we: (1) designed a stratified MSS to estimate late autumn abundance...

Comparative demography of new world populations of thrushes (Turdus spp.): Comment
Paul B. Conn, Paul F. Doherty Jr., James D. Nichols
2005, Ecology (86) 2536-2541
Survival and fecundity are fundamental to the study of evolutionary ecology, as they are two of the key variables influencing the constrained optimization process we call natural selection. Likewise, population managers require accurate estimates of these parameters; along with dispersal, they govern population dynamics (Lack 1954) and...
A comparison of campfire impacts and policies in seven protected areas
S. E. Reid, Jeffrey L. Marion
2005, Environmental Management (36) 48-58
Using resource-monitoring data from seven protected areas, the effectiveness of three campfire policies—campfire ban, designated campfires, and unregulated campfires—were assessed based on the number of fire sites and the amount of tree damage. Results indicate that unregulated campfire policies permitted substantial numbers of fire sites and tree damage in campsites,...

W. Battaglin, L. Hay, G. McCabe, P. Nanjappa, Alisa L. Gallant
2005, Alytes (22) 146-167
Amphibians occupy a range of habitats throughout the world, but species richness is greatest in regions with moist, warm climates. We modeled the statistical relations of anuran and urodele species richness with mean annual climate for the conterminous United States, and compared the strength of these relations at national and...
Fine-scale spatial variation in plant species richness and its relationship to environmental conditions in coastal marshlands
J.E. Mancera, G.C. Meche, P.P. Cardona-Olarte, E. Castaneda-Moya, R.L. Chiasson, N.A. Geddes, L.M. Schile, H.G. Wang, G.R. Guntenspergen, J.B. Grace
2005, Plant Ecology (178) 39-50
Previous studies have shown that variations in environmental conditions play a major role in explaining variations in plant species richness at community and landscape scales. In this study, we considered the degree to which fine-scale spatial variations in richness could be related to fine-scale variations in abiotic and biotic factors....
Salt tolerance underlies the cryptic invasion of North American salt marshes by an introduced haplotype of the common reed Phragmites australis (Poaceae)
Edward A. Vasquez, Edward P. Glenn, J. Jed Brown, Glenn R. Guntenspergen, Stephen G. Nelson
2005, Marine Ecology Progress Series (298) 1-8
A distinct, non-native haplotype of the common reed Phragmites australis has become invasive in Atlantic coastal Spartina marshes. We compared the salt tolerance and other growth characteristics of the invasive M haplotype with 2 native haplotypes (F and AC) in greenhouse experiments. The M haplotype retained 50% of its growth...
A curious pellet from a great horned owl (Bubo virginianus)
N. Woodman, C.J. Dove, S.C. Peurach
2005, Northeastern Naturalist (12) 127-132
One of the traditional methods of determining the dietary preferences of owls relies upon the identification of bony remains of prey contained in regurgitated pellets. Discovery of a pellet containing a large, complete primary feather from an adult, male Ring-necked Pheasant (Phasianus colchicus) prompted us to examine in detail...
Use of radio-telemetry to reduce bias in nest searching
Larkin A. Powell, J. D. Lang, David G. Krementz, Michael J. Conroy
2005, Journal of Field Ornithology (76) 274-278
We used traditional searching, as well as radio-telemetry, to find 125 Wood Thrush (Hylocichla mustelina) nests during 1994–1996 at the Piedmont National Wildlife Refuge in Georgia, USA. We compared daily nest survival rates for 66 nests of radio-marked birds with 59 nests of birds found through systematic searching. By...

Luis Albuja V., Alfred L. Gardner
2005, Proceedings of the Biological Society of Washington (118) 442-449
We describe Lonchophylla orcesi, sp. nov., from the Choco, a region of high biotic diversity, endemism, and rainfall along the western Andean slopes and Pacific lowlands of Colombia and Ecuador. One of the largest known Lonchophylla, it occurs sympatrically with at least two other species of Lonchophylla including the similar,...
A general class of multinomial mixture models for anuran calling survey data
J. Andrew Royle, William A. Link
2005, Ecology (86) 2505-2512
We propose a general framework for modeling anuran abundance using data collected from commonly used calling surveys. The data generated from calling surveys are indices of calling intensity (vocalization of males) that do not have a precise link to actual population size and are sensitive to factors that influence anuran...
Plant species invasions along the latitudinal gradient in the United States
Thomas J. Stohlgren, David Barnett, Curtis Flather, John Kartesz, Bruce G. Peterjohn
2005, Ecology (86) 2298-2309
It has been long established that the richness of vascular plant species and many animal taxa decreases with increasing latitude, a pattern that very generally follows declines in actual and potential evapotranspiration, solar radiation, temperature, and thus, total productivity. Using county-level data on vascular plants from the United States (3000...
Double-observer approach to estimating egg mass abundance of vernal pool breeding amphibians
Evan H. Campbell Grant, Robin E. Jung, James D. Nichols, James E. Hines
2005, Wetlands Ecology and Management (13) 305-320
Interest in seasonally flooded pools, and the status of associated amphibian populations, has initiated programs in the northeastern United States to document and monitor these habitats. Counting egg masses is an effective way to determine the population size of pool-breeding amphibians, such as wood frogs (Rana sylvatica) and spotted salamanders...

Susan C. Adamowicz, Charles T. Roman
2005, Wetlands (25) 279-288
New England salt marsh pools provide important wildlife habitat and are the object of on-going salt marsh restoration projects; however, they have not been quantified in terms of their basic geomorphic and geographic traits. An examination of 32 ditched and unditched salt marshes from the Connecticut shore of Long Island...
Seed dispersal into wetlands: Techniques and results for a restored tidal freshwater marsh
K. P. Neff, Andrew H. Baldwin
2005, Wetlands (25) 392-404
Although seed dispersal is assumed to be a major factor determining plant community development in restored wetlands, little research exists on density and species richness of seed available through dispersal in these systems. We measured composition and seed dispersal rates at a restored tidal freshwater marsh in Washington, DC, USA...

R.E. Jung, J. Andrew Royle, J.R. Sauer, C. Addison, R.D. Rau, J.L. Shirk, J.C. Whissel
2005, Alytes (22) 72-84
Stream salamanders in the family Plethodontidae constitute a large biomass in and near headwater streams in the eastern United States and are promising indicators of stream ecosystem health. Many studies of stream salamanders have relied on population indices based on counts rather than population estimates based on techniques such...
Dynamic design of ecological monitoring networks for non-Gaussian spatio-temporal data
C. K. Wikle, J. Andrew Royle
2005, Environmetrics (16) 507-522
Many ecological processes exhibit spatial structure that changes over time in a coherent, dynamical fashion. This dynamical component is often ignored in the design of spatial monitoring networks. Furthermore, ecological variables related to processes such as habitat are often non-Gaussian (e.g. Poisson or log-normal). We demonstrate that a simulation-based design...
