An Assessment Of Potential Habitat Corridors And Landscape Ecology For Long-Tailed Macaques (Macaca Fascicularis) On Bali, Indonesia, Mark Warren Southern

All Master's Theses

The relationship between Balinese long-tailed macaques, Bali's cultural settings, and Bali's physical settings was studied. A Geographical Information System (GIS) database was developed and analyzed to determine if forest corridors exist on Bali that may provide habitat connectivity between 42 Balinese long-tailed macaque troops. The GIS database was also analyzed to determine if the landscape type that has the highest percentage of overlap with the 42 Balinese long-tailed macaque home range sites is forest. The results indicate that connectivity between troops located within Bali's western region is significantly higher than that for troops located in Bali's eastern region. The results …

Compositional Trends And Spatial Patterns Over A Quarter Century: Forest Dynamics Of Dobbs Park, Indiana, Nancy Hoalst Pullen

All-Inclusive List of Electronic Theses and Dissertations

Thirty-five permanent plots were reexamined to identify and describe the spatial and temporal characteristics of Dobbs Park, an isolated old-growth forest stand in westcentral Indiana. The 3.6 ha stand was resurveyed in summer 2000, with all stems greater than 10 cm dbh measured, and accessions and deaths recorded. The results are compared to original data collected in summer 1974, with compositional and spatial patterns identified via GIS and spatial analysis. The stand has declined slightly in density from 342 stems/ha to 333.15 stems/hectare (-2.6%) while basal area (dominance) for the stand has increased from 23.6 m2/ha to 25.8 m2/ha (+8.8%) …

Effects Of Excessive Nitrogen Deposition On Foliar Nutrient Dynamics, Nutrient Concentrations, And Nutrient Ratios In A Central Appalachian Hardwood Forest, Sarah Beth Burdette

Theses, Dissertations and Capstones

Many forested systems of the eastern US are becoming significantly nitrogen (N) saturated due to chronic N deposition from the atmosphere. Nitrogen saturation has the potential to alter important internal plant processes, such as nutrient cycling. While extensive research has been conducted on the responses of soil to N saturation, considerably less research has focused on the response of plant nutrient dynamics, nutrient concentrations, and nutrient ratios to excess N. Research was conducted on two watersheds at the Fernow Experimental Forest in West Virginia: WS3 (fertilized with ammonium sulfate annually since 1989) and WS7 (untreated control). Presenescent and senesced leaves …

Are Pileated Woodpeckers Attracted To Red-Cockaded Woodpecker Cavity Trees?, Richard N. Conner, Daniel Saenz, James R. Mccormick

Faculty Publications

Pileated Woodpeckers (Dryocopus pileatus) cause damage to Red-cockaded Woodpecker (Picoides borealis) cavity trees in the form of cavity enlargement or other excavations on the surface of the pine tree. However, it is not known whether Pileated Woodpeckers excavate more frequently on Red-cockaded Woodpecker cavity trees than on noncavity trees or how stand structure is related to the frequency of Pileated Woodpecker excavation. Also, it is unclear whether the cavity itself provides the stimulus to Pileated Woodpeckers to excavate or whether the presence of Red-cockaded Woodpeckers and their activities are attracting them. We surveyed all of the …

Prey Handling And Diet Of Louisiana Pine Snakes (Pituophis Ruthveni) And Black Pine Snakes (P. Melanoleucus Lodingi), With Comparisons To Other Selected Colubrid Snakes, D. Craig Rudolph, Shirley J. Burgdorf, Richard N. Conner, Christopher S. Collins, Daniel Saenz, Richard R. Schaefer, Toni Trees, C. Michael Duran, Marc Ealy, John G. Himes

Faculty Publications

Diet and prey handling behavior were determined for Louisiana pine snakes (Pituophis ruthveni) and black pine snakes (P. melanoleucus lodingi). Louisiana pine snakes prey heavily on Baird's pocket gophers (Geomys breviceps), with which they are sympatric, and exhibit specialized behaviors that facilitate handling this prey species within the confines of burrow systems. Black pine snakes, which are not sympatric with pocket gophers, did not exhibit these specialized behaviors. For comparative purposes, prey handling of P. sayi sayi and Elaphe obsoleta lindheimeri was also examined.

Movement Patterns Of Resident And Relocated Northern Bobwhites In East Texas, Xiangwen Liu, R. Montague Whiting Jr., D. Scott Parsons, Donald R. Dietz

Faculty Publications

We compared home range sizes and movement patterns of resident and relocated northern bobwhites (Colinus virginianus) on an area managed specifically for the species in the Pineywoods of east Texas. During the winters of 1990–1992, 155 south Texas, 136 east Texas, and 139 resident bobwhites were radiomarked, released, and thereafter regularly located. Bird locations were plotted on a digitized map, and home range sizes and movement patterns of each group of birds were estimated. Resident bobwhites moved longer daily distances in March and had larger home ranges during the nesting season (May-Jul) than relocated birds (P0.05). Managers that elect to …

Monitoring Herpetofauna In A Managed Forest Landscape: Effects Of Habitat Types And Census Techniques, Travis J. Ryan, Thomas Philippi, Yale A. Leiden, Michael E. Dorcas, T. Bently Wigley, J. Whitfield Gibbons

Scholarship and Professional Work - LAS

We surveyed the herpetofaunal (amphibian and reptile) communities inhabiting five types of habitat on a managed landscape. We conducted monthly surveys during 1997 in four replicate plots of each habitat type using several different methods of collection. Communities of the two wetland habitats (bottomland wetlands and isolated upland wetlands) were clearly dissimilar from the three terrestrial communities (recent clearcut, pine plantation, and mixed pine–hardwood forest). Among the three terrestrial habitats, the total herpetofaunal communities were dissimilar (P<0.10), although neither faunal constituent group alone (amphibians and squamate reptiles) varied significantly with regard to habitat. Three survey techniques used in the terrestrial habitats were not equally effective in that they resulted in the collection of different subsets of the total herpetofauna. The drift fence technique revealed the presence of more species and individuals in every habitat and was the only one to detect species dissimilarity among habitats. Nonetheless, coverboards contributed to measures of abundance and revealed species not detected by other techniques. We suggest that a combination of census techniques be used when surveying and monitoring herpetofaunal communities in order to maximize the detection of species.

Temporal And Spatial Variation Of Nitrogen Transformations In Nitrogen-Saturated Soils Of A Central Appalachian Hardwood Forest, Frank S. Gilliam, Bradley M. Yurish, Mary Beth Adams

Biological Sciences Faculty Research

We studied temporal and spatial patterns of soil nitrogen (N) dynamics from 1993 to 1995 in three watersheds of Fernow Experimental Forest, W.V.: WS7 (24-year-old, untreated); WS4 (mature, untreated); and WS3 (24-year-old, treated with (NH4)2SO since 1989 at the rate of 35 kg Nha–1year–1). Net nitrification was 141, 114, and115 kg Nha–1year–1, for WS3, WS4, and WS7, respectively, essentially 100% of net N mineralization for all watersheds. Temporal (seasonal) patterns of nitrification were significantly related to soil moisture and ambient temperaturein untreated watersheds only. Spatial patterns of soil water NO3–of WS4 suggest that microenvironmental variabilitylimits rates of N processing in …

Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller

Other Publications in Wildlife Management

The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvicultural practices on goshawk breeding habitat (Reynolds-1983, Bloom et al 1986, Kennedy 1989, Crocker-Bedford 1990). Current and past research efforts on the Kaibab Plateau have mapped Goshawk nesting territories and temporal change in nesting behavior and success. However, these research efforts have not determined how long-term spatial changes in land-use activities that have influenced …

The Forester's Dilemma : Paradoxes In The Criteria And Indicators For Sustainable Forestry, Theodore E. Howard

New Hampshire Agricultural Experiment Station Publications

Since sustainable forestry is a complex endeavor, paradoxes naturally exist in the certification criteria and indicators. There are different ways to establish the sustainability horizon and alternative harvest profiles that, although sustainable, may not meet specific criteria. The application of historic range of variation data and criteria must confront issues of time and spatial scales as well as how much human disturbance is natural. Defining “local” in the bioregional context is important for addressing socioeconomic criteria. The forester’s ability to deal with the self-contradictions in the criteria and indicators of sustainable forestry will improve with experience in the certification process.

A Red-Cockaded Woodpecker Group With Two Simultaneous Nest Trees, Richard N. Conner, James R. Mccormick, Richard R. Schaefer, Daniel Saenz, D. Craig Rudolph

Faculty Publications

During a study of Red-cockaded Woodpecker (Picoides borealis) nesting in eastern Texas, we discovered a single breeding pair of woodpeckers with two simultaneous nests in nest trees that were 24 m apart. Incubation of eggs in each nest tree was at least 13 d and may have been as long as 16 d. The breeding male incubated and fed a nestling in one nest tree, and the breeding female incubated and fed a nestling in the other nest tree until the nestlings were >24 d old. Prior to fledging, both the breeding male and female were observed feeding …

An Unusually Large Number Of Eggs Laid By A Breeding Red-Cockaded Woodpecker Female, Richard N. Conner, Daniel Saenz, James R. Mccormick

Faculty Publications

The Red-cockaded Woodpecker (Picoides borealis) is a cooperatively breeding species that typically uses a single cavity for nesting (Ligon 1970, Walters et al. 1988). A single tree, or aggregation of cavity trees, termed the cluster, is inhabited by a group of woodpeckers that includes a single breeding pair and up to several helpers, which are typically male offspring of previous breeding seasons (Ligon 1970, Lennartz et al. 1987). Each group of Red-cockaded Woodpeckers usually produces one nest per breeding season, but will often nest again during the same breeding season if the first nest fails. Double clutching and …

Factors Influencing Spatial Variability In Nitrogen Processing In Nitrogen-Saturated Soils, Frank S. Gilliam, Charles C. Somerville, Nikki L. Lyttle, Mary Beth Adams

Biological Sciences Faculty Research

Nitrogen (N) saturation is an environmental concern for forests in the eastern U.S. Although several watersheds of the Fernow Experimental Forest (FEF), West Virginia exhibit symptoms of Nsaturation, many watersheds display a high degree of spatial variability in soil N processing. This study examined the effects of temperature on net N mineralization and nitrification in N-saturatedsoils from FEF, and how these effects varied between high N-processing vs. low N-processingsoils collected from two watersheds, WS3 (fertilized with [NH4]2SO4) and WS4 (untreated control). Samples of forest floor material (O2 horizon) and mineral soil (to a 5-cm depth) were taken from three subplots …

Integrating Liana Abundance And Forest Stature Into An Estimate Of Total Aboveground Biomass For An Eastern Amazonian Forest, Jeffrey J. Gerwing, Damiao Lopes Farias

Environmental Science and Management Faculty Publications and Presentations

This study provides an estimate of aboveground live biomass for an intact eastern Amazonian forest. An allometric regression biomass equation was developed to estimate the aboveground biomass of live lianas. This equation, together with a previously published equation for trees, was then used to estimate the contributions of lianas and trees to the total biomass of forest patches in four stature classes: gap (openings in the canopy of at least 25 m2 with the dominant vegetation < 3 m high), low (3±15 m canopy height), medium (15±25 m canopy height), and high (> 25 m canopy height). Total stand-level biomass was estimated as the weighted average of the stature classes. In 130 ha of surveyed forest, forest …

Life In A Pine Cone, David L. Kulhavy

Faculty Publications

This exercise focuses on a little-known microhabitat -- the pine cone. A pine cone's primary function is, of course, reproduction ... housing the seeds of the next generation of conifer trees. However, pine cones are also the basis of a food web that provides both resources and living space for a wide variety of small arthropod species. The procedure outlined below is designed to examine this microhabitat and compare its community diversity among different species of conifers and habitats.

The exercise is based on a 1985 paper, Life in a Pine Cone, by David L. Kulhavy, Robert S. Baldridge and …

Food Plot Use By Juvenile Northern Bobwhites In East Texas, D. Scott Parsons, R. Montague Whiting Jr., Xiangwen Liu, Donald R. Dietz

The Effects Of Forest Fragment Size, Isolation, And Microhabitat Variables On Nest Box Use By Southern Flying Squirrels (Glaucomys Volans) In Southern Illinois, Catherine Wong, Eric K. Bollinger, Thomas A. Nelson

Faculty Publications

We studied the effects of forest fragmentation on southern flying squirrels (Glaucomys volans) in southern Illinois, and examined factors influencing nest box use. Ten nest boxes were placed in each of 30 oak-hickory forest fragments. Nest boxes were checked monthly after installation. We measured habitat variables that described the nest box tree, the microhabitat surrounding the nest box tree, and landscape level characteristics of the fragments (isolation and area). Overall, 78% of the 300 nest boxes were used. Glaucomys volans was captured in 24 of the 30 forest fragments, and evidence of squirrel use was found in 4 additional fragments. …
