Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard

Karl Reinhard Publications

Mummification was not intentional for most North American prehistoric cultures. Natural mummification occurred in the dry areas of North America, where mummies have been recovered from rock shelters, caves, and overhangs. In these places, corpses desiccated and spontaneously mummified. In North America, mummies are recovered from four main regions: the southern and southwestern United States, the Aleutian Islands, and the Ozark Mountains of Arkansas. This chapter is limited to a discussion of burial practices and a tabulation of the location of mummies in the southwestern United States with some comments on mummies of the southern United States, including the Ozarks.

An Ecology Problem Book, Marc Mangel, Paul Switzer, Sarah M. Eppley

Biology Faculty Publications and Presentations

This problem book has many objectives:

• To get you to think about the course each night: do not wait until the last minute to begin working on the problems.
• To get you to deal with data. Statistics courses that you take in the future will be more meaningful once you understand the kinds of data that arise in ecological studies.
• To get you to be more comfortable with theoretical and quantitative methods. Not every ecologist uses those methods, but one should not be put off by them.
• To familiarize you with material as it appears in the professional literature.

4. The localized input of fixed nitrogen by termites …

Locational Factors Determining The Distribution Of Nesting Sites For A Colony Of Wedge-Tailed Shearwaters, Puffinus Pacificus, On West Wallabi Island, Houtman Abrolhos, Western Australia, Julie Davis

Theses : Honours

West Wallabi Island in the Houtman Abrolhos, Western Australia, provides significant breeding habitat for the largest colony of Wedge-tailed Shearwaters, Puffinus pacificus, in the Eastern Indian Ocean. The Department of Conservation and Land Management (CALM) surveyed the Island in 1992 and estimated the population to be in excess of 1,117,000 pairs of breeding birds. Recent proposals to open the Abrolhos area to a larger number of visitors has identified the need for more detailed investigations into the relationship of birds and habitat. An understanding of this relationship provides a means of determining the ways in which populations will respond to …

Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill

Biology Faculty Publications

The larval chondrocranium and visceral skeleton of Dendrobates auratus ls described and compared with those of other dendrobatids. Four characters, i.e. lack of fusion between orbital cartilages and otic capsules, wide processus muscularis palatoquadrati, lack of processus pseudopterygoideus, and lack of processus anterolateralis hyalis, represent derived conditions for Dendrobates within Dendrobatidae. Cranial and postcranial ossification sequences are reported for D. auratus and Epipedobates tricolor. Skeletogenesis is earlier in E. tricolor, but the overall pattern of ossification is similar in the two species.

Habitat Selection, Reproductive Success, And Impaling Patterns Of A Migratory Population Of Loggerhead Shrikes, Jeffrey D. Esely Jr.

Masters Theses

I studied habitat selection and reproductive success of a migratory population of Loggerhead Shrikes (Lanius ludovicianus migrans) as well as the temporal and spatial patterns of impaling exhibited by this population during the nesting season. The selection of breeding habitat was investigated at different spatial scales. Thirty-eight (67%) of 57 nests were located in osage orange (Maclura pomifera) trees. Shrike territories (area ≤ 200 m from nest site) contained significantly more pasture, fenceline, and perch sites, but less com, alfalfa, and forest than random sites. At larger spatial scales, more grassland was detected within 300 m …

A Comparison Of Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison

Masters Theses

I compared rates of predation between real and artificial nests of grassland birds in order to test the impact of nest type, nest position, and egg size on predation rates. I distributed wicker avicultural baskets and realistic grass nests baited with a clay egg and either northern bobwhite (Colinus virginianus) or house sparrow (Passer domesticus) eggs in four Conservation Reserve Program (CRP) grasslands in east-central Illinois. Nest success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nest success was markedly lower; averaging 39% over the entire nesting cycle and 59% during approximately 12 days of …

Interaction Between National Environmental Marketing Regulations And International Trade, Pirkko-Liis Harkmaa

LLM Theses and Essays

The environmental marketing of goods and products have a substantial influence on the demand and supply. This thesis reviews the scope, advantages and disadvantages of diverse types of environmental marketing and further addresses the need for international regulations on eco-labeling programs. This thesis finds that there is a substantial connection between trade and environmental marketing which has resulted in the need for an international harmonization of eco-labeling strategies including the General Agreements on Tariffs and Trade (GATT). The thesis concludes with propositions for a uniform international standard on eco-labeling for the adoption of environmentally-sound best practices and the mitigation of …

Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross

Biological Sciences Theses & Dissertations

Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …

Farrowing Behaviour And Stillbirth In Two Environments: An Evaluation Of The Restraint-Stillbirth Hypothesis, D. Fraser, P. A. Phillips, B. K. Thompson

Reproductive Behavior Collection

A total of 59 farrowings were studied in either a conventional, narrow farrowing crate (0.43 m wide) or a much wider alternative design with sides spaced 1.2 m apart at the sow’s standing height but narrowing near the floor to limit the sow’s lying area. Using video recording, we monitored each “birth interval” (i.e. the period between two successive births) and noted the interval’s length, the sow’s posture and postural changes during the interval, and whether the interval ended with a live-born or stillborn piglet. The wide and conventional crates did not differ significantly in median interval between piglets (15.9 …

Effect Of Artificial Flooding On The Vegetation And Avifauna Of Riparian Woodlands At Santa Ana National Wildlife Refuge, Hidalgo County, Texas, Charles David Castillo

Theses and Dissertations - UTB/UTPA

Riparian habitats along the Rio Grande at Santa Ana National Wildlife Refuge have dramatically decreased since the construction of Falcon Dam in 1953. Riparian habitats are dependent on annual or periodic flooding to maintain their biological integrity. Lack of seasonal flooding has contributed to changes in vegetative composition from riparian forests to thornscrub. Effects of artificial flooding on vegetation and avifauna of riparian woodlands were evaluated from 1995-1997 at the Santa Ana National Wildlife Refuge. Floodwaters caused the destruction of all existing herbaceous species along study transects and the regeneration of new and native seedlings. Avian abundance and diversity dramatically …

Breeding Densities And Habitat Of Riparian Birds Along The Lower Rio Grande, Texas, Corinna Elizabeth Rupert

Theses and Dissertations - UTB/UTPA

The breeding biology of Snowy Plovers (Charadrius alexanderinus) was studied at Laguna Atascosa National Wildlife Refuge in coastal southern Texas. During 1995 and 1996 nests were found most often in high sand flat habitat and less frequently in low sand flat. Nest sites were dominated by open flat but had more rocks, pebbles and debris than control sites. Only 24% of the clutches hatched, while 67% were eaten by predators and 9% were flooded. Forty-three percent of Snowy Plover nests were within Least Tern (Sterna antillarum) colonies and these nests had a significantly greater chance of hatching than nests placed …

Management Options For Pilbara Demersal Line Fishing, Gaye Looby

Fisheries Management Papers

Fisheries Western Australia licensing arrangements allow all vessels with an unrestircted fishing boat licence ('wetline licence') to take scalefish throughout the State. These arrangements have led to a high level of excess capacity in the licensed 'wetline' fishing fleet to exploit the scalefish resources. The declaration of the Kimberley Interim Line Fishery and forthcoming declaration the Northern Demersal Scalefish Fishery have resolved this problem for the Kimberley waters. However, the high level of excss capacity in the 'wetline' fleet to exploit the waters of the Pilbara remains a problem Preview access and develop a management plan for the Pilbara demersal …

Wildlife-Caused Losses For Catfish Producers In 1996, Alice P. Wywialowski

Wildlife Damage Management Conference

In January 1997, the National Agricultural Statistics Service (NASS) surveyed catfish producers about wildlife-caused losses in 1996, Of the 1,465 catfish producers in 15 states surveyed, 1,008 (68.8%) agreed to complete the survey. Surveys were conducted primarily by telephone, but some producers received mail surveys. The response rated varied among states. The majority of catfish producers were in Mississippi (n=-300), followed by Alabama (n=163), and then Arkansas (n=117). The remaining states each had < 100 respondents. Data were analyzed for 6 regions, each with a sample size of > 100 respondents. Overall, 69% of catfish producers cited a wildlife-caused loss of catfish. Producers cited losses to wildlife most frequently in Mississippi (81%), followed by states adjoining …

Electric Fencing Reduces Heron Predation At Northeastern Trout Hatcheries, Mark E. Tobin, James F. Glahn, Erica S. Rasmussen

Wildlife Damage Management Conference

Great blue herons (Ardea herodius) are the most common avian predator at commercial trout hatcheries in the northeastern United States. We evaluated a 2-strand electric fence for excluding this species from raceways at 2 commercial trout hatcheries in central Pennsylvania. Fences consisted of high density polyethylene 400-lb strength tape supported by fiberglass posts and energized by either a battery-powered or a solar-powered fence charger. Labor and material for constructing the fences at the 2 sites averaged $1.32/m of raceway. Bird visitation at the 2 sites initially declined, but returned to pre-installation levels. However, bird use of raceways declined …

Double-Crested Cormorant And Ring-Billed Gull Damage Management On Lake Champlain: Are Basin-Wide Objectives Achievable?, Richard Chipman, Dennis Slate, Larry Garland, David Capen

Wildlife Damage Management Conference

Ring-billed gulls (Larus delewarensis) and double-crested cormorants (Phalacrocorx auritus) have nested on Lake Champlain since 1949 and 1982, respectively. Recent increases in cormorant nesting populations and pioneering activities of both species to previously uncolonized islands have resulted in impacts related to accumulation of bird guano and interspecific competition with less common species. Of primary concern are: decreases in wildlife and plant diversity on islands; reduced aesthetics and property values of island associated with the loss of trees; and predation or competition for nesting space with other species such as the state-endangered common tern (Sterna hirundo …

Nesting Populations Of Double-Crested Cormorants, Great Blue Herons, And Great Egrets In The United States And Canada: Implications For Management, Jerrold L. Belant, Laura A. Tyson

Wildlife Damage Management Conference

Populations of piscivorous birds in North America are receiving increasing attention in the southeast United States because of depredations at aquaculture facilities. We obtained recent (most since 1994) estimates for the number of nesting double-crested cormorants (Phalacrocorax auritus), great blue herons (Ardea herodias), and great egrets (Casmerodius albus) in the United States (US) and Canada from published references and by conducting telephone interviews with state and provincial biologists. Using previously-published data, we also determined annual rates of change in the number of cormorants since about 1990. Estimates for minimum numbers of nesting pairs (minimum …

The Legal Roles And Responsibilities Of A Community Concerning Crop Depredation By White-Tailed Deer, Eric G. Darracq, Stephen R. Chapman

Wildlife Damage Management Conference

The interwoven issues of the legal roles and responsibilities that landowners (i.e., farmers, foresters, and hunters) and a state agency have to control deer densities in rural areas that directly affect crop depredation and various stakeholders will be addressed in this paper. Because unmanaged deer populations severely can damage agricultural crops, the financial cost of this deer damage is borne entirely by individual private landowners. The South Carolina Department of Natural Resources (SCDNR) is the regulatory state agency in South Carolina responsible for annually promulgating rules and regulations pertaining to white-tailed deer harvest by hunters. Even though deer are property …

Wildlife Damage To Agricultural Crops In Pennsylvania: The Farmers' Perspective, Margaret C. Brittingham, Walter M. Tzilkowski, James M. Zeidler, Matthew J. Lovallo

Wildlife Damage Management Conference

Agricultural damage by wildlife is a major concern for both agricultural and wildlife agencies at the state and federal level. Our objective was to estimate wildlife damage to agricultural crops on a statewide basis. We sent questionnaires to 4,958 farmers and 1,003 were returned after 2 mailings. Twenty-five percent of farmers responding to our survey rated the level of wildlife damage to their crops as severe or very severe, 46% as moderate, and 29% had none or very little. Mean levels of crop loss to wildlife ranged from 6% for wheat to 10% for corn grain, and white-tailed deer ( …

Development Of The Virginia Cooperative Coyote Control Program To Protect Livestock, Martin Lowney, John Houben, Phil Eggborn

Wildlife Damage Management Conference

The Virginia Cooperative Coyote Control Program was created in 1990 to address increasing livestock losses to coyotes and the inability of producers to solve such problems themselves. The eastern coyote arrived in Virginia in the late 1970s or early 1980s. Lobbying efforts of agricultural groups, such as the Virginia Sheep Federation, helped create a cost-share program administered by the Virginia Department of Agriculture and Consumer Services (VDACS) and U.S. Department of Agriculture-Animal and Plant Health Inspection Service-Wildlife Services (USDA-APHIS-WS). The objective of the program was to educate producers about control methods and to alleviate damage by removing offending coyotes where …

Wildlife Damage Management Conference

In response to needs within the aquaculture industry to alleviate increasing depredation by double-crested cormorants (Phalacrocorax auritus), the U.S. Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services, in conjunction with Federal, State, and Canadian wildlife and fisheries agencies, the aquaculture industry, and other wildlife professionals, is developing the framework for a comprehensive cormorant damage management program that uses an integrated wildlife damage management approach. This cooperative effort will produce a meaningful, mutually beneficial program that will reduce the effects of cormorants on aquaculture and sport and commercial fisheries, improve understanding of cormorant biology, and avert …

Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor

Veterinary Science and Medicine Collection

Relative body size (carapace width) and weapon size (chela length) were used as indicators of resource holding potential (RHP) in the agonistic behaviour of male shore crabs, Carcinus maenas (L.). Weapon size was found to be a more reliable predictor of the outcome of pairwise fights than body size. Crabs with longer chelae than their opponents were more likely to win fights than crabs with relatively larger bodies. Body size had less influence on the outcome of fights. Relative body and weapon size did not influence initiation of contests but did affect the likelihood of winning; however, this was significant …

Site-Dependent Regulation Of Population Size: A New Synthesis, Nicholas L. Rodenhouse, Thomas W. Sherry, Richard T. Holmes

Dartmouth Scholarship

The nature and extent of population regulation remains a principal unanswered question for many types of organisms, despite extensive research. In this paper, we provide a new synthesis of theoretical and empirical evidence that elucidates and extends a mechanism of population regulation for species whose individuals preemptively use sites that differ in suitability. The sites may be territories, refuges from predation, oviposition sites, etc. The mechanism, which we call site dependence, is not an alternative to density dependence; rather, site dependence is one of several mechanisms that potentially generate the negative feedback required for regulation. Site dependence has two major …

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

We surveyed the mollusks of the Niobrara River in Nebraska from 1992–1996. We found two species of unionid clams and ten species of snails that either must live in water or near water. Both clams and snails are poorly sampled in the state, however we attribute the low number of species of unionid clams in the Niobrara to its cold, fast flow and rocky bottom. In contrast, the Platte River is slower moving with a muddy bottom and has at least 11 species of unionid clams. Each species has been mapped with latitude/longitude coordinates. Specimens have been curated and are …
