"Historical Processes And The Political Organization Of The Hasinai Caddo Indians": A Reply, Nancy Adele, Timothy K. Perttula
"Historical Processes And The Political Organization Of The Hasinai Caddo Indians": A Reply, Nancy Adele, Timothy K. Perttula
Index of Texas Archaeology: Open Access Gray Literature from the Lone Star State
In a recent volume of the Caddoan Archeology Newsletter, Daniel Hickerson argues that Apache aggression across the Southern Plains, Apache trade in horses and other European goods, and European-introduced diseases dramatically affected Caddo an populations by encouraging their migration south to the upper Neches/Angelina river basins area traditionally occupied by one segment of the Caddo, the Hasinai groups. In his opinion, the Hasinai confederacy was a nascent chiefdom that developed as a direct result of this mid to late-seventeenth century southern migration. As has been pointed out by Caddoan ethnographers, ethnohistorians, and archeologists for 50 years or more, the Caddo …

Food Of Cobia, Rachycentron Canadum, From The Northcentral Gulf Of Mexico, Gabriele H. Meyer, James S. Franks
Gulf and Caribbean Research
The stomach contents of 403 cobia, Rachycentron canadum, caught in the northcentral Gulf of Mexico recreational fishery from April through October of 1987-1990 were examined. Cobia ranged from 373-1,530 mm in fork length. Of the 403 stomachs, 287 (71.2%) contained at least one identifiable prey taxon. Crustaceans, consisting primarily of portunid crabs, were the predominant food. Crustaceans occurred in 79.1% of the stomachs and comprised 77.6% of the total number of identifiable prey. The second most important prey category was fish which was dominated by hardhead catfish, Arius felis, and eels. Fish occurred in 58.5% of the stomachs …
Reproductive Strategies In A Population Of Gobiosoma Bosci (Osteichthyes: Gobiidae) With Slow And Fast Maturing Individuals, Candace H. Conn, David L. Bechler
Reproductive Strategies In A Population Of Gobiosoma Bosci (Osteichthyes: Gobiidae) With Slow And Fast Maturing Individuals, Candace H. Conn, David L. Bechler
Gulf and Caribbean Research
The reproductive biology of Gobiosoma bosci collected from November 1986 to October 1987 in the McFaddin Wildlife Refuge in southeast Texas was studied by using morphometric data. Males achieved greater weights per unit length than females, and longevity was about 12 to 13 months. GSI values and mean monthly ovum diameters indicated that the breeding season ran from April to September, with a major activity peak in May and a minor peak in September. Significant differences in male and female standard lengths (SL), ovum diameter, and egg number existed for sexually mature specimens between the first and second peaks of …

Analysis Of Vertebrate Pest Research, Jim Hone
Analysis Of Vertebrate Pest Research, Jim Hone
Vertebrate Pest Conference Proceedings: 17th (1996)
Research on vertebrate pest control is mostly empirical, focusing on control of species X in location Y using method Z. Such an approach is needed. The science of vertebrate pest research is developing some generalizations across species, locations, and methods. This paper further explores such generalizations by discussing six questions asked by Hone (1994), the answers to which are relevant to vertebrate pest research world-wide. Several case studies are examined, with emphasis on control of damage by small mammals and predation control. Suggestions are made for future research.
The Potential Impact Of Introduced Commensal Rodents On Island Flora, Gillian Key, Renata Platenberg, Andrew Easby, Kathleen Mais
The Potential Impact Of Introduced Commensal Rodents On Island Flora, Gillian Key, Renata Platenberg, Andrew Easby, Kathleen Mais
Vertebrate Pest Conference Proceedings: 17th (1996)
The impact of introduced commensal rodents on island flora has been relatively little studied compared with their impact on the fauna. The effects on vegetation composition, regeneration, and decomposition are largely unknown, but potentially great. Preliminary studies were carried out in the Galapagos Islands between 1993 and 1994 on the diet of introduced rats, Rattus spp. and feral house mice, Mus musculus, seed recovery rates and subsequent germination rates of seeds. R. rattus diet was primarily vegetation and 48% of rats had seeds in their stomachs. Significant differences were found between body size and overall contribution of both …
Mongolian Rangelands: Rodent Problems And Approaches To Alleviate Damage, Dale L. Nolte
Mongolian Rangelands: Rodent Problems And Approaches To Alleviate Damage, Dale L. Nolte
Vertebrate Pest Conference Proceedings: 17th (1996)
Rodents are a major constraint to forage production for livestock in Mongolia. A technical program to identify the magnitude of the problem and strengthen the research capabilities of Mongolian rodent specialists was initiated in 1994. The Brandt's vole is the most widespread and the most detrimental rodent to the steppes of Mongolia. Limited resources inhibit activities by the Mongolian Plant Protection Service to reduce rodent populations. Alternative means to monitor vole activity were developed. Laboratory and field trials showed that voles were susceptible to zinc phosphide treatment and indicated how bait acceptance could be improved.

Population Densities And Disease Surveys Of Wild Pigs In The Coast Ranges Of Central And Northern California, Rick A. Sweitzer, Ian A. Gardner, Ben J. Gonzales, Dirk Van Vuren, Walter M. Boyce
Vertebrate Pest Conference Proceedings: 17th (1996)
In 1994 and 1995, 233 different wild pigs were captured during population research at seven research sites focused primarily in the coastal regions of central and northern California. Mark-resight data and information on wild pig movements were used to assess wild pig population densities at those sites. Population densities ranged from 1.01 wild pigs/km2 in Mendocino County in 1994 to 3.32 wild pigs/km2 in Santa Clara County in 1995. Comparisons of population densities between years at three research sites suggested that wild pig populations increased in 1995 in response to favorable forage conditions after the wet fall and …

Biofilm Mediated Calculus Formation In The Urinary Tract, Robert J. C. Mclean, David J. Stickler, J. Curtis Nickel
Biofilm Mediated Calculus Formation In The Urinary Tract, Robert J. C. Mclean, David J. Stickler, J. Curtis Nickel
Cells and Materials
Mineralization and subsequent calculus formation is a common complication of biofilm infections. In the urinary tract, these infected calculi often arise from infections by urease-producing bacteria. Ammonia, liberated by bacterial urease activity, increases urine pH, resulting in the precipitation of Ca and Mg as carbonateapatite {Ca10(PO4,CO3)6(OH,CO3)2} and struvite (NH4MgP04·6H2O). These minerals become entrapped in the organic matrix which surrounds the infecting organisms and ultimately grow into mature calculi. When the causative organisms grow on urinary catheters and stents, the resulting mineralization can …
Evapotranspiration From A Saltcedar-Dominated Desert Floodplain: A Scaling Approach, S. D. Smith, A. M. Sala, Dale A. Devitt
Evapotranspiration From A Saltcedar-Dominated Desert Floodplain: A Scaling Approach, S. D. Smith, A. M. Sala, Dale A. Devitt
Life Sciences Faculty Research
The purpose of this study was to investigate evapotranspiration (ET) from a variety of scales (leaf to landscape) in saltcedar-dominated floodplain vegetation along the lower Virgin River of southern Nevada. Leaf-level gas exchange indicated that saltcedar exhibits similar stomatal conductance as the sympatric phreatophytes arrowweed, mesquite, and willow. However, sap flow in saltcedar was higher per unit sapwood area than the other species, suggesting that it maintains higher leaf area per unit sapwood area. At the stand level, saltcedar ET was found to exceed potential ET early in the summer when soils were moist and the water table was near …

Residential Radon-222 Exposure And Lung Cancer: Exposure Assessment Methodology, R. William Field, Daniel J. Steck, Charles F. Lynch, Christine P. Brus, John S. Neuberger, Burton C. Kross
Residential Radon-222 Exposure And Lung Cancer: Exposure Assessment Methodology, R. William Field, Daniel J. Steck, Charles F. Lynch, Christine P. Brus, John S. Neuberger, Burton C. Kross
Physics Faculty Publications
Although occupational epidemiological studies and animal experimentation provide strong evidence that radon-222 (222Rn) progeny exposure causes lung cancer, residential epidemiological studies have not confirmed this association. Past residential epidemiological studies have yielded contradictory findings. Exposure misclassification has seriously compromised the ability of these studies to detect whether an association exists between 222Rn exposure and lung cancer. Misclassification of 222Rn exposure has arisen primarily from: 1) detector measurement error; 2) failure to consider temporal and spatial 222Rn variations within a home; 3) missing data from previously occupied homes that currently are inaccessible; 4) failure to link …

Pluralism, Science, Ethics, And The Intersecting Spheres Of Social Concerns And Environmentalism, Christopher B. Barrett, Raymond E. Grizzle
Pluralism, Science, Ethics, And The Intersecting Spheres Of Social Concerns And Environmentalism, Christopher B. Barrett, Raymond E. Grizzle
Economic Research Institute Study Papers
This paper builds on alternative perspectives offered by the environmental and sustainability traditions to advance a holistic yet practical conceptual model that explicitly integrates social and environmental concerns. Ours is a pluralistic approach founded on synthesis. Employing the economic concept of path dependence, we emphasize that there exist multiple paths society can follow in environmental ethics and policy, but that onc e one has been chosen, implicitly or explicitly, there may be little opportunity to reverse such choices. Hence, the importance of process to the pursuit of social and environmental objectives.

Diet And Seasonal Feeding Habits Of The Yellow Stingray, Urolophus Jamaicensis, T. Patrick Quinn
Diet And Seasonal Feeding Habits Of The Yellow Stingray, Urolophus Jamaicensis, T. Patrick Quinn
HCNSO Student Theses and Dissertations
Urolophus jamaicensis, the yellow stingray, is a common elasmobranch found on and around the coral reefs off Florida's southeastern coast. Its diet consists of polychaetes, crustaceans, nemerteans, sipunculids, nematodes, and chaetognaths with polychaetes and crustaceans comprising almost 67% of the stomach contents by volume. There does not appear to be any diet preference between the male and females stingrays. The seasonal changes in diet preference are limited to an increase in the proportion of polychaetes found in the stomach during spring when compared to fall.
The Law Of Sustainable Development, Nicholas A. Robinson
The Law Of Sustainable Development, Nicholas A. Robinson
Elisabeth Haub School of Law Faculty Publications
I am going to talk briefly, as dictated by the format of this seminar, about the law of sustainable development and how it has been developing. Sustainable development is, today, the guiding theme for both public and private measures to improve social conditions and strengthen economic conditions around the world. It did not become a guiding theme overnight. The recognition that sustainable development is fundamental has been growing gradually. The concept recognizes that the sort of development that was popular in the 1960s and 1970s in the United States of America and elsewhere was, by itself, an inadequate base on …

Top-Down Cascade From A Bitrophic Predator In An Old-Field Community, Matthew D. Moran, Thomas P. Rooney, L. E. Hurd
Top-Down Cascade From A Bitrophic Predator In An Old-Field Community, Matthew D. Moran, Thomas P. Rooney, L. E. Hurd
Biological Sciences Faculty Publications
We tested the hypothesis that a bitrophic (third and fourth level) arthropod predator can exert a cascading, top-down influence on other arthropods and plants in an early successional old field. First-stadium mantids, Tenodera sinensis, were added to replicated open-field plots in numbers corresponding to naturally occurring egg hatch density and allowed to remain for ≈ 2 mo. Sticky-trap dispersal barriers around both control and mantid-addition plots allowed us to monitor emigration of arthropods continuously during the experiment. Biomass of herbivores, carnivores, and plants, and abundances of arthropod taxa within plots were determined at the beginning, middle, and end of …
