Effects Of Zebra Mussel (Dreissena Polymorpha) Colonization On Water Quality Parameters In Saginaw Bay, Lake Huron, Gary L. Fahnenstiel, Gregory A. Lang, Thomas F. Nalepa, Thomas H. Johengen Jan 1995

Effects Of Zebra Mussel (Dreissena Polymorpha) Colonization On Water Quality Parameters In Saginaw Bay, Lake Huron, Gary L. Fahnenstiel, Gregory A. Lang, Thomas F. Nalepa, Thomas H. Johengen

United States Department of Commerce: Staff Publications

A large-scale study of Saginaw Bay was initiated in 1990 and continued through 1993 to examine the effects of the zebra mussel colonization which began in summerlfall 1991. Saginaw Bay responded quickly to the zebra mussel colonization, as fall 1991 values of chlorophyll were similar to 1992 and 1993 values. In inner Saginaw Bay, where most zebra mussels were found, chlorophyll, kPAR, and total phosphorus values decreased, and Secchi disk depth increased during the study period, regardless of the presence or absence of zebra mussels at a specific station. At outer bay control stations no significant differences were found for …

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 …

Coyotes: A South Texas Perspective, Rick Sramek Jan 1995

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: 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 …

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 …

Coyote Population Processes Revisited, Frederick F. Knowlton, Eric M. Gese Jan 1995

Coyote Population Processes Revisited, Frederick F. Knowlton, Eric M. Gese

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

It appears that coyote (Canis latrans) abundance is determined primarily by availability of food (prey) as mediated through social dominance hierarchies and a territorial land tenure system. This is reflected in rates of reproduction, dispersal, and mortality, with survival of juveniles a major factor. Suggestions for a new generation of simulation models to explore coyote population functions are included.

Effects Of Coyote Control On Their Prey: A Review, Scott E. Henke Jan 1995

Effects Of Coyote Control On Their Prey: A Review, Scott E. Henke

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

Coyotes (Canis latrans) are often removed from an area because of their predatory nature, regardless of the effect such removal may have on the ecosystem. Research results concerning ecosystem changes due to coyote removal appear ambiguous; however, differing lengths of coyote control can produce different results. Short-term coyote removal efforts (≤ 6 months) typically have not resulted in increases in the prey base; however, long-term, intensive coyote removal reportedly has altered to alter species composition within the ecosystem.

Coyotes And Upland Gamebirds, Fred S. Guthrey Jan 1995

Coyotes And Upland Gamebirds, Fred S. Guthrey

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

That coyotes (Canis latrans) destroy nests and individuals of bobwhites (Colinus virginianus) and wild turkeys (Meleagris gallopavo) is well documented. In many situations, however, the removal of coyotes would have little observable effect on gamebird recruitment and population dynamics. This counterintuitive result occurs because (1) renesting reduces the hen failure rate and (2) loss sources other than coyotes become stronger when coyotes are removed from a predator–prey system.

Predation Impacts And Management Strategies For Reducing Coyote Damage To Cattle, Rickey L. Gilliland Jan 1995

Predation Impacts And Management Strategies For Reducing Coyote Damage To Cattle, Rickey L. Gilliland

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

Loss of cattle to predators influences productivity of many livestock operations. Statistics indicate that coyote (Canis latrans) predation is a principle threat. Impacts to livestock resources by coyotes are appraised. Implementation of control strategies which capitalize on coyote dispersion and social interactions are discussed. Predator management to reduce livestock losses and promote a younger age structure in coyotes is suggested as a long term solution.
