Initial Colonization Of The Zebra Mussel (Dreissena Polymorpha) In Saginaw Bay, Lake Huron: Population Recruitment, Density, And Size Structure, Thomas F. Nalepa, James A. Wojcik, David L. Fanslow, Gregory A. Lang Jan 1995

Initial Colonization Of The Zebra Mussel (Dreissena Polymorpha) In Saginaw Bay, Lake Huron: Population Recruitment, Density, And Size Structure, Thomas F. Nalepa, James A. Wojcik, David L. Fanslow, Gregory A. Lang

United States Department of Commerce: Staff Publications

The various life stages of the zebra mussel (Dreissena polymorpha) were examined during the initial years (1991-93) of the mussel's invasion into Saginaw Bay, Lake Huron. Yearly trends in densities of larvae, newly-settled juveniles, and adults were poorly related. Larval densities were lowest in 1991 and increased each year, but the number of settled juveniles was highest in 1991. Adults increased between 1991 and 1992 and then declined in 1993. Mean adult densities at sites with hard substrates were 11,700,33,200, and 4,1001m2 in each of the 3 years, respectively. Year-to-year variation at individual sites was high and likely …

Geomorphic And Geochemical Evidence For The Source Of Sand In The Algodones Dunes, Colorado Desert, Southeastern California, Daniel R. Muhs, Charles A. Bush, Scott D. Cowherd, Shannon Mahan Jan 1995

Geomorphic And Geochemical Evidence For The Source Of Sand In The Algodones Dunes, Colorado Desert, Southeastern California, Daniel R. Muhs, Charles A. Bush, Scott D. Cowherd, Shannon Mahan

United States Geological Survey: Staff Publications

The Algodones dunes of southeastern California comprise one of the largest active dune fields in the United States. The source of sand of the Algodones dunes is controversial, and the source of stabilized aeolian sand in the adjacent East Mesa area has not been investigated at all. We used mineralogical compositions and trace element concentrations to ascertain the most likely source of sand for these active and stabilized dunes. Results indicate that alluvium derived from the San Bernardino Mountains, which enters the Salton trough to the northwest of the dune fields, and alluvium derived from the Chocolate Mountains, which is …

Rangeland Reference Areas : Summary Of Cooperative Project Between The Western Australian Department Of Agriculture And The Environmental Protection Authority, D A. Blood Jan 1995

Rangeland Reference Areas : Summary Of Cooperative Project Between The Western Australian Department Of Agriculture And The Environmental Protection Authority, D A. Blood

Resource management technical reports

The development of agriculture in south-western Australia has been characterised by the replacement of deep-rooted, perennial species of native vegetation with shallow-rooted, annual species. Except for the high rainfall areas, the native vegetation was able to intercept and transpire nearly all of the rainfall resulting in low stream flows and recharge to a groundwater system which was typically deep and restricted to the major valleys. The lack of surface or groundwater movement out of inland catchments used large quantities of cyclic salts to become stored in the regolith. Although annual crops and pastures can be high water users, they are …

Filtration Rates Of The Zebra Mussel (Dreissena Polymorpha) On Natural Seston From Saginaw Bay, Lake Huron, David L. Fanslow, Thomas F. Nalepa, Gregory A. Lang Jan 1995

Filtration Rates Of The Zebra Mussel (Dreissena Polymorpha) On Natural Seston From Saginaw Bay, Lake Huron, David L. Fanslow, Thomas F. Nalepa, Gregory A. Lang

United States Department of Commerce: Staff Publications

Filtration rates of the zebra mussel (Dreissena polymorpha) on natural seston from two different regions in Saginaw Bay were determined on a monthly basis from April to October in 1992 and 1993. The two regions represent contrasting trophic conditions, with the inner bay more eutrophic than the outer bay. Mean filtration rate was 16.2 mL/mg/h (range 4.0 to 40.7 mL/mg/h) over the entire 2-year period. Filtration rates on seston from the inner bay were significantly lower than rates on seston from the outer bay in 1992, but no differences were apparent in 1993. Lower rates were attributed to …

Inorganic Nitrogen Determined By Laboratory And Field Extractions Of Two Forest Soils, H. Van Miegroet Jan 1995

Inorganic Nitrogen Determined By Laboratory And Field Extractions Of Two Forest Soils, H. Van Miegroet

Watershed Sciences Faculty Publications

To assess the effect of a delay in soil processing on inorganic N levels in N-rich soils, field and laboratory extractions were compared at two forested sites with high N mineralization and nitrification potential. At eight sampling dates in 1989 and 1990, five mineral soil cores per site were taken between 0- and 10-cm depth and transported on ice to the laboratory for KCl extraction and NH4-N and NO3-N analysis. At three sampling dates in 1990, soil extractions were performed in the field immediately following sampling, and inorganic N concentrations were compared between extractions. Nitrate-N increased four- to sevenfold (net …

Bermuda Solution Pipe Soils: A Geochemical Evaluation Of Eolian Parent Materials, Stanley R. Herwitz, Daniel R. Muhs Jan 1995

Bermuda Solution Pipe Soils: A Geochemical Evaluation Of Eolian Parent Materials, Stanley R. Herwitz, Daniel R. Muhs

United States Geological Survey: Staff Publications

Solution pipes found in the Quaternary eolian and marine carbonates of Bermuda are filled with reddish to reddish-brown soil material. The bulk of the soil is composed of clay and silt-sized quartz and aluminosilicate clay minerals. The carbonates are of high purity and, therefore, are not likely to have been the parent material. Previous workers have hypothesized that Saharan dust may have been the soil parent material. The fine-grained component of loess from the Mississippi River Valley of North America also could have contributed. Paleoclimate models indicate that both North Africa and North America could have been important source areas …

Impact Of Erosion, Mass Wasting, And Sedimentation On Human Activities In The Río Grande Basin, Jujuy Province, Argentina, Waldo Chayle, William J. Wayne Jan 1995

Impact Of Erosion, Mass Wasting, And Sedimentation On Human Activities In The Río Grande Basin, Jujuy Province, Argentina, Waldo Chayle, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Nearly all dry mountainous regions are affected by severe erosion, floods, and debris flows during times of intense precipitation. The lithology, geologic structure, and climate in Jujuy Province, Argentina combine to place at serious risk the people who live along the Río Grande, the major river that drains the east side of the Cordillera Oriental and the west side of the Sierras Subandinas. Nearly all precipitation falls during summer (January–March) with little during the remainder of the year; most of the basin is semiarid to arid, although the southern end has a humid subtropical climate. Relief is great, as much …

Coyotes: A Potential Role In Deer Herd Management?, Robert E. Zaiglin Jan 1995

Coyotes: A Potential Role In Deer Herd Management?, Robert E. Zaiglin

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

White-tailed deer (Odocoileus virginianus) herd control is one of the principal problems faced by private lands game managers. Private landowners unwilling to permit adequate numbers of sport hunters on their lands force deer managers to exercise other harvest strategies, one of which is natural population control by protecting the coyote (Canis latrans). I describe an ongoing case study in South Texas where predation by coyotes may be considered a positive tool in deer population management.

Coyotes: A South Texas Perspective, Rick Sramek

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Coyotes (Canis latrans) are abundant throughout North America, some of the highest densities occur in south Texas. Most studies indicate abundance of food as a contributing factor of coyote density. High coyote populations can lead to localized depredation problems and the current canine rabies epizootic is of concern to residents of south Texas.

Predator Politics In Texas, Bill Sims Jan 1995

Predator Politics In Texas, Bill Sims

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The coyote (Canis latrans) is certainly one of the most destructive predators affecting the livestock industry, particularly sheep and goats. In fact, title of this session is very appropriate, because when you talk about “politics”, coyotes seem to have more politicians working for them than any other animal.

Predator Politics: Personal Thoughts And Perceptions, Milo J. Shult

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

My career as an extension wildlife specialist and a university administrator has allowed me to monitor both the public and private sectors' perspectives on coyotes (Canis latrans) and their associated management policies. Selected experiences described herein illustrate the problems (current and future) that characterize emotionally-charged conflicts like those typified by coyote control efforts.

Coyotes: A Matter Of Perspective, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Predators and predator management in general are always controversial topics. As with most controversies, both ends of an emotional continuum vie for the attention of the nonvocal, uncommitted majority. To provide unbiased information on the controversy surrounding coyotes (Canis latrans) in Texas, the Texas Agricultural Extension Service produced a 23-minute video in 1991. The video addresses both sides of the coyote coin while providing factual biological information on the topic. The video has been quite popular, and has received both state and national awards.

Coyotes In The Southwest: Dedication To Samuel L. Beasom, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

This symposium is dedicated to the life, achievements and memory of Samuel L. Beasom. From the first time that I considered trying to assemble this symposium, Sam Beasom was on my list of key people to include. Sam's professional contributions and his dry wit would surely play a pivotal role in a conference on coyotes in the Southwest, especially one to be conducted in Texas. I never dreamed then that his contributions, and subsequent recognition, would be presented posthumously here today.

The Livestock Protection Collar For Removing Depredating Coyotes: A Search For Perfect Justice?, Dale Rollins Jan 1995

The Livestock Protection Collar For Removing Depredating Coyotes: A Search For Perfect Justice?, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Lethal control techniques for controlling coyotes (Canis latrans) are often maligned as a means for resolving coyote depredations on domestic livestock. With the exception of the Livestock Protection Collar (LPC), lethal control methods (e.g., foot-hold traps and neck snares) lack the ability to specifically remove those coyotes actually preying upon livestock. The LPC capitalizes on attack behavior of coyotes to remove offending individuals. Although currently registered for use in 5 states, LPCs have been used routinely only in Texas. Success with LPCS involves an understanding of coyote behavior and proper targeting of collared livestock. LPCs have been used …

Public Attitudes Toward Predators In Texas, Douglas Reiter, Mark W. Brunson, Robert H. Schmidt

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A national survey of public attitudes to ward wildlife damage management provided the opportunity to extract a data set from Texas respondents on predator management Texas respondents were generally more supportive of predator control for livestock protection than the rest of the U S., although the overall trends were similar. Lethal technologies scored low on a humaneness scale.

The Re-Establishment Of The Coyote In The Edwards Plateau Of Texas, Gary Lee Nunley Jan 1995

The Re-Establishment Of The Coyote In The Edwards Plateau Of Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

In the early 1900s organized predator control was initiated to remove coyotes (Canis latrans) and wolves (C. lupus and C. rufus) from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920s, many of the inner Edwards Plateau counties were considered to be almost free of coyotes and wolves In the 1950s coyotes and wolves were extirpated from most of the Edwards Plateau After a coyote population irruption in the early 1960s, coyotes began to re-establish themselves on the periphery …

Sheep And Goat Losses In Relation To Coyote Damage Management In Texas, Gary Lee Nunley Jan 1995

Sheep And Goat Losses In Relation To Coyote Damage Management In Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The average reported sheep and goat loss to coyotes (Canis latrans) in 1992 on those properties worked by the cooperative animal damage control program were relatively low. Sheep and goat losses were not evenly distributed among the producers. Geographical distribution of the losses reflected a positive relationship between relative coyote density and livestock losses. The sheep and goat industry is adversely affected by the cumulative losses of those producers suffering high levels of predation.

Immunocontraception As A Tool For Controlling Reproduction In Coyotes, Lowell A. Miller Jan 1995

Immunocontraception As A Tool For Controlling Reproduction In Coyotes, Lowell A. Miller

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The development of immunocontraception as a tool for population management of coyotes (Canis latrans) and reduction of coyote predation may provide an environmentally safer alternative to pesticides. Because they are proteins, immunocontraceptive vaccines do not persist in the environment or bioaccumulate in the food chain. The National Wildlife Research Center (NWRC) will examine the effects (immunological, hormonal and behavioral) of treating penned coyotes with 2 immunocontraceptive vaccines: porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH). Initial studies will be conducted using traditional subcutaneous injections; however, the goal IS to develop an orally-deliverable immunocontraceptive vaccine as an alternative …
