From The Gulf To The Rio Grande: Human Adaptation In Central, South, And Lower Pecos Texas, Thomas Hester, Stephen L. Black, D. Gentry Steele, Ben W. Olive, Anne A. Fox, Karl Reinhard, Leland C. Bement
Karl Reinhard Publications
The South Texas area, Region 3 of the Southwestern Division, U.S. Army Corps of Engineers, is synthesized from archeological and bioarcheological perspectives. Three distinct geographic units within Region 3 are treated in detail: Central Texas Plateau Prairie, South Texas Plains, and Lower Pecos Canyonlands. More than 11,000 years of human adaptation are chronicled for this area, stretching from the Gulf of Mexico to the Rio Grande along the border with northeastern Mexico. Particular attention is devoted to a consideration of the region's prehistoric record; significant problems and data gaps are outlined. For the first time, a compilation has been done …
A Mimbres Burial With Associated Colon Remains From The Nan Ranch Ruin, New Mexico, Harry J. Shafer, Marrianne Marek, Karl J. Reinhard
A Mimbres Burial With Associated Colon Remains From The Nan Ranch Ruin, New Mexico, Harry J. Shafer, Marrianne Marek, Karl J. Reinhard
Karl Reinhard Publications
The skeletal remains of an adult male associated with desiccated tissue and a coprolite were recovered from an apen-air midden deposit at the NAN Ranch Ruin (LA15049)) a large Mimbres site in Grant County) New Mexico. The find dates to about A.C. 1000-1100. Identifiable macroscopic elements in the caprolite consist offi nely fragmented corn and tiny seed fragments of an unknown plant. High amounts of willow (Salix) and mustard (Brassicaceae) pollen may indicate the ingestion of medicinal plants to combat a deteriorating health condition. The individual was approximately 35 -40 years old at the time of death and suffered from …

Bioarcheological Synthesis For "From The Gulf To The Rio Grande: Human Adaptation In Central, South, And Lower Pecos Texas", Karl Reinhard, Ben W. Olive, D. Gentry Steele
Karl Reinhard Publications
One of the main problems encountered in the review of the bioarcheology of Region 3 has been the limited number of sites where human skeletal material has been adequately recovered and analyzed. In the preceding chapter it was documented that less than 30% of the burials recovered from recorded sites have been reported in published literature. It was further estimated that of the 323 sites with burials, no more than 80 sites have published detailed bioarcheological reports on the burials recovered. Only 50 of these 80 reports provide individual descriptions of each burial which facilitate subsequent analyses and evaluation.

Short Term Temporal And Spatial Variability Of Phytoplankton In The Elizabeth River, Robert L. O'Reilly
Short Term Temporal And Spatial Variability Of Phytoplankton In The Elizabeth River, Robert L. O'Reilly
Biological Sciences Theses & Dissertations
This study was designed to evaluate short-term temporal and spatial components of phytoplankton variability within a tidal estuarine system, in reference to natural changes in the local environment.
Multiple water samples were collected weekly from October to December 1984 at 4 stations in different branches, or sections, of the Elizabeth River. Collection of chlorophyll~ data was structured to fit an analysis of variance, while the phytoplankton species and their environmental relationships were analyzed using multivariate techniques.
Lower chlorophyll a concentrations from 0.75 to 2.87 ug/1 were characteristic of the Main Stem and Southern Branch, while higher values of 1.27 …
Helminth Remains From Prehistoric Indian Coprolites On The Colorado Plateau, Karl J. Reinhard, Richard H. Hevly, Glenn A. Anderson
Helminth Remains From Prehistoric Indian Coprolites On The Colorado Plateau, Karl J. Reinhard, Richard H. Hevly, Glenn A. Anderson
Karl Reinhard Publications
Examination of coprolites excavated from archaeological sites in the Americas demonstrates excellent preservation of helminth eggs and, in some cases, larvae. To gain an understanding of helminth parasitism in prehistory on the Colorado Plateau of Arizona, New Mexico, and Utah, 319 coprolites from 5 archaeological sites were analyzed. Helminth eggs and larvae were recovered after the coprolites were rehydrated, screened, and sedimented. At a sixth site, soils excavated from 5 rooms used as latrine areas were processed with palynological techniques. The results indicate that all but 1 of the prehistoric populations examined were infected with intestinal worms. The helminths implicated …
Wildlife And Nature Liberation, Michael W. Fox
Wildlife And Nature Liberation, Michael W. Fox
Conservation Collection
Humane ethics--animal welfare--and animal rights are not incompatible with ecologically sound wildlife stewardship. They are an integral part of it, from treating wildlife for necessary research purposes humanely, to finding humane ways to control the populations of species that are out of balance and thus threatening the viability of other species and the diversity and integrity of the ecosystem. That mistakes may be made in stewardshipmanagement policies is inevitable. It is, for instance, difficult to know if the sudden abundance of one or more species and the dwindling of others is part of the natural process of succession and should …
Wildlife Conservation And Animal Rights: Are They Compatible?, Michael Hutchins, Christen Wemmer
Wildlife Conservation And Animal Rights: Are They Compatible?, Michael Hutchins, Christen Wemmer
Conservation Collection
The purpose of this paper is to explore the philosophical tenets of the animal rights/humane ethic as they relate to the environmental ethic and, more specifically, as they relate to wildlife management and conservation. The two ethics will be compared in an effort to identify potential sources of conflict. Recent criticisms of the animal rights ethic, most notably by Fox (1978, 1979), Rodman (1977), Callicott (1980), Gunn (1980), and Hutchins et al. (1982) have identified several major discrepancies. The implications of these differences will be discussed.
Reproductive Wastage In Sheep, R W. Kelly
Reproductive Wastage In Sheep, R W. Kelly
Journal of the Department of Agriculture, Western Australia, Series 4
The average lambing performance of Western Australia's ewe flock fluctuates between 60 and 70 per cent. Although this level of performance and variation between years is important for the sheep industry, individual farmers are more concerned about performance of their own flocks.
Figure shows the range in lambing performances that exist between farms in this State in 1983-84. The seriously poor performance of many flocks is apparentm - 28 percent of farms had less than 60 per cent lambing. By contrast, 24 farms had performances better than 100 per cent. The reasons for the large differences between farms ( and …
Recovery Of Helminths From Prehistoric Feces: The Cultural Ecology Of Ancient Parasitism, Karl J. Reinhard
Recovery Of Helminths From Prehistoric Feces: The Cultural Ecology Of Ancient Parasitism, Karl J. Reinhard
Karl Reinhard Publications
Several helminth parasites have been recovered from archaeological sites on the Colorado Plateau. These include Ascaris, Trichuris, Enterobius, Moniliformis, and tapeworms in the families Hymenolepidae and Taeniidae. The recovery of these animals demonstrates that cross-temporal: comparison of parasitism between different prehistoric lifestyles is possible. Such comparison might elucidate the effects of changing lifestyle and subsistance pattern on human parasitism.
Desiccated feces recovered from archaelogical deposits were studied. Hunter-gatherer feces were selected from Dust Devil Cave in southeastern Utah. Agriculturalist feces were studied from Antelope House, a cave site in northeastern Arizona, and Salmon Ruins, a Pueblo …
The Distribution Of Ceratia Over The Mid-Atlantic Bight, Paul V. Zimba
The Distribution Of Ceratia Over The Mid-Atlantic Bight, Paul V. Zimba
Biological Sciences Theses & Dissertations
The distribution and concentration of Ceratium species, between Cape Hatteras, North Carolina and Long Island, New York ls discussed in relation to specific physical factors and the development of a phytoplankton bloom. The progression of high Ceratium counts Is discussed for the Bight areas of New York, Delaware, and the Chesapeake Bay (April through June). The concentration of Ceratium species declined after June, with highest concentrations along the New York and Delaware coast-lines. Coastal regions (less than 12 km from shore) were associated with high concentrations of several species. Path and regression analysis were used to relate physical factors and …

A Survey Of Drench Resistance In Sheep Worms, J R. Edwards, R. Wroth, G. C. De Chaneet, R. B. Besier, J. Karlsson, P. W. Morcombe, D. Roberts, G. Dalton-Morgan
Journal of the Department of Agriculture, Western Australia, Series 4
Sheep worms which are resistant to chemical drenches have been detected with increasing freuency is Western Australia's south-western farming areas between 977 and 1980. These worms have anthelmintic resistance and such genetis resistance puts essential internal parasite control practices at risk.
This prompted veterinarians in the Esperance, Albany, Bunbury, Geraldton and Northam areas to survey farms to determine the prevalence of resistance to drenches and to define those sheep management practices which encourage its development.
This article describes the survey which was conducted to assess the extent of drench resistance, what causes its build-up and how it can be controlled …
Whales Are Not Cetacean Resources, Dale Jamieson, Tom Regan
Whales Are Not Cetacean Resources, Dale Jamieson, Tom Regan
Conservation Collection
What we know about whales is sufficient for ascribing to them the analogues of human rights, including the fundamental right to be treated with respect. Once we recognize their possession of this right, it follows that whales are not to be used or exploited by us for the promotion of our ends, however "benign" they may appear. In the case of humans, to refrain from killing them is to discharge only a small part of our total duties. We must also refrain from exploiting them, whether "consumptively" or "nonconsumptively." Having come as far as we have in our understanding of …
Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel
Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel
Masters Theses
Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
Karl Reinhard Publications
Multi-individual cremation deposits found in the upper Santa Cruz River drainage were previously interpreted as the result of hypothesized cultural contact in the area. A review of 50 cremation deposits for which detailed analyses are available indicates that mulii-individual cremation deposits are the result of incomplete gleaning practices and have doubtful cultural significance. Hypotheses are generated from the present data which account for the apparent variation in cremation practices within the study area.
Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii
Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii
Biological Sciences Theses & Dissertations
The dynamics of epiphytic algae and phytoplankton were studied at a cypress stand in the Great Dismal Swamp, Virginia. Mean epiphytic algal biomass was 19.9 g m-2 and mean planktonic biomass was 3.4 g m-2.Nutrient concentrations in the epiphytic algae and the litter were determined. The algae had mean concentrations of 1.67% and 0.18%. They were found to immobilize as much as 0.5 g N m-2 and 0.06 g P m-2. This suggests that the algae are important as nutrient conservers. The phytoplankton were composed primarily of Bacillariophyceae. They exhibited a more or less …

Hematology As Related To Diving Characteristics Of Elaphe Obsoleta, Nerodia Erythrogaster, Nerodia Fasciata And Nerodia Rhombifera, Dennis A. Baeyens, M. W. Patterson, Chris T. Mcallister
Journal of the Arkansas Academy of Science
The diving capabilities of Nerodia erythrogaster flavigaster and Nerodia fasciata confluens were investigated and the results were compared with similar studies on Nerodia rhombifera rhombifera and Elaphe obsoleta obsoleta (Baeyens et al., 1978). In addition, morphological and hematological parameters contributing to underwater survival were examined. The duration of underwater survival for N. erythrogaster and N. fasciata was approximately one hour with no difference between the species. The lung volumes of the two species were also similar but were significantly less than lung volumes reported for E. obsoleta. There were no significant differences in hemoglobin concentration, red blood cell count or …

Prehistoric Cremations From Nogales, Arizona *, Karl J. Reinhard, Jeff H. Shipman
Karl Reinhard Publications
In October, 1969, the Highway Salvage Section of the Arizona State Museum conducted emergency salvage excavations in conjunction with the construction of the Tucson-Nogales Highway. Ten cremations were recovered from a backhoe trench which had been placed within the city limits of Nogales, Arizona. Analysis of the cremations indicated cultural contact between the Trincheras culture of Sonora, Mexico, and the Hohokam culture of the Santa Cruz River Valley in southern Arizona.

The Behaviour Of Swine, J. P. Signoret, B. A. Baldwin, D. Fraser, E. S. E. Hafez
Mammalogy Collection
The pig was a forest-dwelling animal from the beginning of its history. In some parts of the world it has been domesticated for at least 7000 years. The European breeds of domestic swine were derived from the local wild pig, Sus scrofa. Herds ranged in pastures and forests and kept indoors only for fattening. The breeds in the Far East were derived from another wild pig, Sus vittatus, a smaller animal with shorter legs and a higher reproductive ability (Mohr 1960; Zeuner 1963). The two types interbred readily. The modem breeds of pig evolved from different crossings between the two …

A Study Of Naturally Occurring Algicides Produced By Freshwater Algae, Denny O. Harris, Harry D. Caldwell
KWRRI Research Reports
The mode of action of the algicide produced by Pandorina morum was examined by exposing Volvox globator and isolates spinach chloroplasts to a partially purified algicide preparation. Oxygen evolution of Volvox, whole chloroplasts and broken chloroplasts (minus the Calvin cycle),was reduced indicating that the algicide inhibits the light reactions of photosynthesis. Oxygen evolution studies of other Volvocaceae confirmed the observation that Pandorina morum is not significantly influenced by its own inhibitor. Molecular weight approximation by gel filtration established that the inhibitor has a low molecular weight (probably below 100 mw). Field studies indicate that this algicide has tremendous potential as …

A Study Of Water-Soluble Inhibitory Compounds (Algicides) Produced By Fresh-Water Algae, Denny O. Harris, Manhar C. Parekh
KWRRI Research Reports
A complex system of growth inhibitors was observed in the green algae (Volvocaceae). Inhibitors were found in the culture filtrates of some genera which limit their own growth (autoinhibitors) while others in the family produce substances which check the growth of other genera (heteroinhibitors). These inhibitors were destroyed by autoclaving. It was decided that Pandorina morum, which produced the strongest inhibitor and Volvox tertius, the most sensitive to the inhibitor would make an excellent model system for a study of the chemical and physical properties of these naturally occurring algicides. The algicide could be removed from actively growing cultures about …

Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill
Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill
Masters Theses
A study was conducted on the alga Chlamydomonas reinhardtii to determine the range and optimum growth concentrations of phosphate and nitrate. There are only a few species of algae for which this type of data is known. Inorganic nutritional data is basic to the understanding of the complexities of phytoplankton ecology and eutrophication.
The "plus" strain of this heterothallic alga was cultured in a TRIS-buffered inorganic medium with various concentrations of sodium phosphate and potassium nitrate and adjusted to a pH of 7.4. The axenic cultures were evaluated at the end of 6 days with a spectrophotometer, at a wavelength …
