Use Of Alpha-Chloralose By Usda Wildlife Services To Immobilize Birds, Jeanette R. O'Hare, John D. Eisemann, Kathleen A. Fagerstone, Lawanna L. Koch, Thomas W. Seamans
Use Of Alpha-Chloralose By Usda Wildlife Services To Immobilize Birds, Jeanette R. O'Hare, John D. Eisemann, Kathleen A. Fagerstone, Lawanna L. Koch, Thomas W. Seamans
United States Department of Agriculture Wildlife Services: Staff Publications
In 1992, the U. S. Food and Drug Administration (FDA) opened an Investigational New Animal Drug (INAD) file for the avian immobilizing agent, alpha-chloralose (AC) for the United States Department of Agriculture, Animal and Plant Health Inspection Service (APHIS). Currently, this INAD authorizes trained Wildlife Services (WS) personnel to use AC to immobilize and live-capture nuisance waterfowl (Anatidae spp.), American coots (Fulica americana), pigeons (Columba livia), common ravens (Corvus corax) and sandhill cranes (Grus canadensis). The use of AC has proven to be a valuable tool for WS and the number …

Overview Of The First Use Of Gps 1991/Gis 1992 During A Wyoming Skunk Rabies Epizootic, Craig A. Ramey, Kenneth H. Mills, Marshall Robin
United States Department of Agriculture Wildlife Services: Staff Publications
Striped skunks (Mephitis mephitis) are one of the most important reservoirs of wildlife rabies on the Great Plains of North America. During a skunk rabies epizootic in a previously rabies-free area of northwestern Wyoming, we studied the spread of rabies from the index case occurring in 1988 until the Shoshone River epizootic ended in 1993. All specimens were sent to the Wyoming State Veterinary Laboratory for Fluorescent Antibody Testing for rabies. The goal of federal, state, county, and local agencies was to address the public's fear about the health and safety of humans and animals. Following several rabid …
Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman
Chlorophacinone Baiting For Belding’S Ground Squirrels, Craig A. Ramey, George H. Matschke, Richard M. Engeman
United States Department of Agriculture Wildlife Services: Staff Publications
The efficacy of using 0.01% chlorophacinone on steam-rolled oat (SRO) groats applied in CA alfalfa by spot-baiting/hand baiting around burrow entrances (~11.5 g) to control free-ranging Belding's ground squirrels (Spermophilus beldingi) were compared in 6 randomly assigned square treatment units (TUs). Four TUs were given the rodenticide and 2 treated with placebo bait. Each TU was a 0.4 ha square surrounded by a similarly treated 5.5 ha square buffer zone. Baits were applied on May 13 and re-applied, on May 20 and May 22, after 7 days of un-forecasted cool wet weather greatly reduced their above ground activity. …
A Broad Perspective On Current And Future Research On Urban Coyotes, John A. Shivik, Kathleen Fagerstone
A Broad Perspective On Current And Future Research On Urban Coyotes, John A. Shivik, Kathleen Fagerstone
United States Department of Agriculture Wildlife Services: Staff Publications
A change in wildlife management appears to be occurring. Previous efforts needed to be focused on producing more game species or endangered animals; now, however, tools and training must resolve issues of overabundance and conflict with predators, especially species such as coyotes (Canis latrans) in urban areas. Urban conflicts with coyotes may be growing because of urban development of land and human intrusion, but alteration of habitats that attract coyotes is also a likely factor. Research that will describe basic coyote biology in urban areas will be needed, but managers will also need applied research and development of …
Modeling Costs Of Using Ovocontrol G For Managing Nuisance Canada Goose (Branta Canadensis) Populations, Joe N. Caudell, Stephanie A. Shwiff
Modeling Costs Of Using Ovocontrol G For Managing Nuisance Canada Goose (Branta Canadensis) Populations, Joe N. Caudell, Stephanie A. Shwiff
United States Department of Agriculture Wildlife Services: Staff Publications
OvoControl G is a relatively new product that reduces the hatchability of Canada goose (Branta canadensis) eggs. However, little data is available on the cost of application. We present a model for estimating the cost of application of OvoControl G for managing nuisance Canada goose populations. We found that at low goose densities, fixed labor costs are responsible for a significant portion of the cost. As goose densities increase, these fixed costs become equivalent to, and eventually less than, the costs associated with the purchase of the product. We present several scenarios that managers may employ to further …
Wildlife Responses To Vegetation Height Management In Cool-Season Grasslands, Brian E. Washburn, Thomas W. Seamans
Wildlife Responses To Vegetation Height Management In Cool-Season Grasslands, Brian E. Washburn, Thomas W. Seamans
United States Department of Agriculture Wildlife Services: Staff Publications
Herbaceous vegetation comprises the main habitat type in cool-seasons grasslands and can be managed by various methods. We compared changes in plant communities and bird and mammal use of grasslands that were not managed, managed by mechanical methods (mowing), or managed by chemical methods (plant growth regulator). This 1-year study was conducted from May through October 2003 in Erie County, Ohio. Twelve circular 1.5 ha plots were established: 4 were not managed, 4 were mowed to maintain vegetation height between 9–15 cm, and 4 were sprayed with a plant growth regulator and mowed when vegetation exceeded 15 cm. We monitored …

Chromaflair® Crow Buster For Repelling Blackbirds And Crows, Scott J. Werner, Shelagh K. Tupper, John L. Cummings
United States Department of Agriculture Wildlife Services: Staff Publications
Nonlethal alternatives are needed to manage emerging and sustained conflicts between humans and several wild birds. We evaluated the ChromaFlair® “Crow Buster,” a device developed in Japan to repel Asian crows from garbage cans, fruit trees, and utility structures. The Crow Buster consists of a strip (1.5-3.5 cm wide) of stiff, shiny plastic cut into a spiral shape. The device is iridescent green-purple in color. We conducted 2 studies to determine the influence of the Crow Buster on the foraging distribution of red-winged blackbirds (Agelaius phoeniceus) and American crows (Corvus brachyrhynchos) in captivity. For both bird …
Rodenticide Use In Rodent Management In The United States: An Overview, Gary W. Witmer, John D. Eisemann
Rodenticide Use In Rodent Management In The United States: An Overview, Gary W. Witmer, John D. Eisemann
United States Department of Agriculture Wildlife Services: Staff Publications
Rodents occur worldwide and have adapted to most types of ecosystems. Rodents provide many important ecosystem functions and while most rodent species do not cause serious damage problems, a small number of species do. Rodent-caused damage includes crop and stored food consumption and contamination, forestry and nursery damage, rangeland damage, ornamental plant damage, property damage, cable and irrigation pipe damage, disease transmission, and, when introduced to islands, damage and even extinction of native flora and fauna. Many tools are used to reduce rodent populations and damage. Rodenticides are an especially important tool in rodent management. Many types of active ingredients …
The Use Of Rodenticides For Conservation Efforts, Gary W. Witmer, John D. Eisemann, Gregg Howald
The Use Of Rodenticides For Conservation Efforts, Gary W. Witmer, John D. Eisemann, Gregg Howald
United States Department of Agriculture Wildlife Services: Staff Publications
Non-native rats (Rattus spp.) and mice have been introduced to more than 80% of the island groups around the world. They have caused ecosystem-wide impacts, including the extirpation and extinction of many native and endemic species which evolved in a mammalian predator-free environment. Fortunately, practitioners have developed techniques to eradicate introduced rodents, allowing ecosystems to recover. Rodenticides have proven an effective tool in eradications, having been used in over 300 successful eradications worldwide. Careful planning, adequate resources, and a sustained effort by competent field staff are needed to help ensure a successful eradication program. Island eradications are logistically complex …

The authors explored some new approaches to describe novel phenomena in particle physics. M Pitkanen introduces his nuclear string hypothesis derived from his Topological Geometrodynamics theory, while E. Goldfain discusses a number of nonlinear dynamics methods, including bifurcation, pattern formation (complex GinzburgLandau equation) to describe elementary particle masses. Fu Yuhua discusses a plausible method for prediction of phenomena related to New Energy development. F. Smarandache discusses his unmatter hypothesis, and A. Yefremov …
Trampling, Peeling And Nibbling Mussels: An Experimental Assessment Of Mechanical And Predatory Damage To Shells Of Mytilus Trossulus (Mollusca: Mytilidae), Carlos E. Cintra-Buenrostro
Trampling, Peeling And Nibbling Mussels: An Experimental Assessment Of Mechanical And Predatory Damage To Shells Of Mytilus Trossulus (Mollusca: Mytilidae), Carlos E. Cintra-Buenrostro
School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations
Shell damage, if properly recognized, can provide information about biotic interactions between molluscs and their predators. However, it can be difficult to distinguish predatory damage from mechanical breakage, thus making interpretation of damaged modern and fossil shells problematic. To establish a clear-cut distinction between antemortem predatory crab damage and ante- and postmortem mechanical damage in Mytilus trossulus shells, a combined field and experimental approach was used. Mussels were exposed to predation by crabs, tumbled-live, tumbled-dead, and trampled. After 100 h of tumbling, live-collected mussel shells were abraded and disarticulated but not otherwise damaged. Eight percent of the dead-collected shells were …
Integrated Guidance For Tidal Shorelines, Center For Coastal Resources Management, Virginia Institute Of Marine Science
Integrated Guidance For Tidal Shorelines, Center For Coastal Resources Management, Virginia Institute Of Marine Science
Reports
Tidal shorelines are the site of complex interactions between terrestrial and aquatic systems. These areas have values that far outweigh their relative size in the larger ecosystem. They are exceptionally important habitat for a wide variety of organisms, some living primarily on land, others that live in water, and a few that are found only in the intertidal zone between land and water. Tidal shoreline systems provide important filtration capacity for materials carried in runoff and groundwater. They are uniquely valued by human users of coastal systems. In Virginia, tidal shoreline systems are managed in small segments, rather than as …
The Fate Of Nitrogren Fixed By Diazotrophs In The Ocean, Margaret R. Mulholland
The Fate Of Nitrogren Fixed By Diazotrophs In The Ocean, Margaret R. Mulholland
OES Faculty Publications
While we now know that N2 fixation is a significant source of new nitrogen (N) in the marine environment, little is known about the fate of this N (and associated C), despite the importance of diazotrophs to global carbon and nutrient cycles. Specifically, does N fixed during N2 fixation fuel autotrophic or heterotrophic growth and thus facilitate carbon (C) export from the euphotic zone, or does it contribute primarily to bacterial productivity and respiration in the euphotic zone? For Trichodesmium, the diazotroph we know the most about, the transfer of recently fixed N2 (and C) appears …
Administering The Clean Water Act: Do Regulators Have "Bigger Fish To Fry" When It Comes To Addressing The Practice Of Chumming On The Chesapeake Bay?, Hope M. Babcock
Administering The Clean Water Act: Do Regulators Have "Bigger Fish To Fry" When It Comes To Addressing The Practice Of Chumming On The Chesapeake Bay?, Hope M. Babcock
Georgetown Law Faculty Publications and Other Works
The Chesapeake Bay is one of the country's most productive estuaries. However, for decades the health of the Bay has been declining due in large part to nutrification. Excessive nutrients encourage algal blooms, which lower dissolved oxygen and increase turbidity in the Bay's waters. More than 40% of the Bay's main stern is now dead largely as a result of this problem. The practice of chumming, the discarding of baitfish, usually menhaden, over the sides of fishing boats to attract game fish like striped bass, is contributing to the Bay's nutrification problem because the decomposing chum raises the waters biological …
Chumming On The Chesapeake Bay And Complexity Theory: Why The Precautionary Principle, Not Cost-Benefit Analysis, Makes More Sense As A Regulatory Approach, Hope M. Babcock
Georgetown Law Faculty Publications and Other Works
Estuaries like the Chesapeake Bay ("Bay") and Puget Sound are in grave trouble. They each suffer from poor water quality, loss of habitat, and declining biodiversity, and efforts to restore their health are straining both public and private resources. While accomplishments are often recorded in the fight against these ills, it is clear these accomplishments "are not yet equal to the scale of the problems." The focus of this article is on the nation's largest estuary, the Bay. Despite the investment of billions of dollars to improve water quality, the Bay continues to suffer from severe environmental degradation that impairs …
Note On The Ndvi-Lst Relationship And The Use Of Temperature-Related Drought Indices Over North America, D. Sun, Menas Kafatos
Note On The Ndvi-Lst Relationship And The Use Of Temperature-Related Drought Indices Over North America, D. Sun, Menas Kafatos
Mathematics, Physics, and Computer Science Faculty Articles and Research
A comprehensive evaluation of the relationship between vegetation and Land Surface Temperature (LST) over the North America is presented. It is found that the correlations between LST and Normalized Difference Vegetation Index (NDVI) depend on the season-of-year and time-of-day. For winter, the correlation between NDVI and LST is positive. The strong negative correlations between LST and NDVI are only found during the warm seasons. Thus temperature-related drought indices may only be used in the warm seasons from May to October, and should be used with caution during cold seasons in North America. The cooling effect of vegetation on LST is …

Natural Resource Management Intermediaries As Potential Next-Users, Jamie Bowyer, Marie Shanks
All other publications
A wide range of individuals and organisations play a role in Natural Resource Management (NRM) in Western Australia currently. Many different service providers also Interact with farmers and land managers to assist or influence farm management decision making. This extensive network has the potential to be tapped by NRM projects to more efficiently influence on-ground practice change. Given the current environment of 'information overload' it is even more important to use these established networks effectively rather than to invent new ones.
This document lists a selection of NRM-related intermediaries and the roles they play in the agricultural sector. Where available, …
