Diet Of The Double-Crested Cormorant In Western Lake Erie, Michael T. Bur, Sandra L. Tinnirello, Charles D. Lovell, Jeff T. Tyson

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Sport and commercial fishing interest groups are concerned about potential impacts double-crested cormorants (Phalacrocorax auritus) may have on fish species. Our objectives for this study were to determine the diet of the cormorant in western Lake Erie and the diet overlap and competition for resources with piscivorous fish, such as walleye (Stizostedion vitreum.) The stomach contents of 302 double-crested cormorants collected in western Lake Erie consisted primarily of young-of-the-year gizzard shad (Dorosoma cepedianum), emerald shiner (Notropis atherinoides,) and freshwater drum (Aplodinotus grunniens). In the spring, freshwater drum were the most …

Double-Crested Cormorant Culling In The St. Lawrence River Estuary: Results Of A 5-Year Program, J. Bedard, A. Nadeau, M. Lepage

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Modeling indicated that lowering the doublecrested cormorant population from 17,361 to 10,000 pairs could be attained only by a combination of techniques: culling breeding birds in arboreal colonies to lower breeding stock and egg spraying in accessible ground nests to lower recruitment. The 5-year program was launched in 1989; culling was halted 4 years later because the population had fallen below the threshold of 10,000 breeding pairs. A greater vulnerability of males to shooting (203:100) probably accounted for the faster-than-predicted drop in numbers. Egg spraying spanned the entire 5-year period, during which 25,095 nests were treated with inert mineral oil. …

Double-Crested Cormorants In The Midwest: Symposium Summary, Francesca J. Cuthbert

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Populations of double-crested cormorants (DCCO’s, Phalacrocorax auritus) have increased dramatically in North America during the past 2 decades (1978–98), especially in the Great Lakes region and Southeastern United States. Concern about the impact, real or imagined, of DCCO’s on economics and ecosystem health has risen in parallel to the increase in cormorant numbers.

A daylong symposium on this subject was opened by Stephen Lewis and D. V. (Chip) Weseloh, who introduced the audience to the general problems associated with cormorants in the Midwest. The moderators identified the following symposium objectives: (1) to provide current information on the status and …

Applications Of Monitoring For Producers, Roy Roath

Range Beef Cow Symposium

The context in which rangeland livestock enterprises operate is changing in the United States. Economic pressures, markets, agency policies, and greater environmental awareness are challenging range livestock operators to mange their operations mare effectively and to respond to meet the challenges of the question "Are you a good steward of the land?" being posed by friend and foe, alike. This debate on land management practices is increasing. Much of this discussion is focusing on conflicts between the multiple uses of the resource. This affects the western livestock industry in a major way because the industry will be judged on its …

Networking People, Barry H. Dunn

Range Beef Cow Symposium

The word networking was one of the buzzwords of the eighties. More recently, it has become one of the hot topics of the swine industry. Networking has been defined as a means of gaining access to a set of advantages which by yourself, or with your own resources, you would not be able to acquire. So networking is about working with other people to gain an advantage. The advantage might be in marketing, information, purchasing, labor, or capital investments. There are examples of successful networks in every human endeavor. History is full of examples. But what does networking have to …

Grazing Animal Diets: When To Supplement, Doug Zalesky

Range Beef Cow Symposium

Despite the fact that we live and operate in the age of technology, the age old question of precisely when to start or when to end supplementation of grazing animals remains. Often the determination of when to begin and when to end supplementation is not based on sound nutritional and/or economic reasons. Currently no one technology or gadget is available that precisely determines when that window of needed supplementation exists. Tradition and the educated guess method has served to make that decision.

The use of such programs as SPA (Standardized Performance Analysis) has allowed producers to more accurately determine the …

Introduction To The Symposium On Double-Crested Cormorants: Population Status And Management Issues In The Midwest, Stephen J. Lewis, D.V. (Chip) Weseloh

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Populations of double-crested cormorants (Phalacrocorax auritus) have increased dramatically in the last 2 decades, particularly in the Great Lakes and the Southeastern United States. Their food habits and propensity for killing the trees in which they nest and roost have made cormorants the subject of much controversy. Cormorants affect—or are perceived to affect—sport fishing, aquaculture operations, vegetation, and other colonial waterbirds. Anglers, aquaculturists, resort operators, lakehome owners, politicians, and others are calling for a solution to these problems. This symposium was convened to provide information that will help conservation agencies and others make sound resource management decisions about …

Nesting Populations Of Double-Crested Cormorants In The United States And Canada, Laura A. Tyson, Jerrold L. Belant, Francesca J. Cuthbert, D.V. (Chip) Weseloh

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Double-crested cormorants (Phalacrocorax auritus) are receiving increasing attention in North America because of depredations at aquaculture facilities and alleged impacts on sport and commercial fisheries. We obtained recent (most since 1994) estimates for the number of nesting double-crested cormorants in the United States and Canada from published references and by conducting telephone interviews with State and Provincial biologists. Using published data, we also determined annual rates of change in the number of cormorants since about 1990. The estimated minimum number of nesting pairs (colonies) of double-crested cormorants was 372,000 (852). Most cormorants nested in the Interior region (68 …

Changes In The Status, Distribution, And Management Of Double-Crested Cormorants In Wisconsin, Summer W. Matteson, Paul W. Rasmussen, Kenneth L. Stromborg, Thomas I. Meier, Julie Van Stappen, Eric C. Nelson

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

We reviewed and summarized historical data and conducted population surveys from 1973 through 1997 to determine the breeding status and distribution of doublecrested cormorants (Phalacrocorax auritus) in Wisconsin. Breeding cormorants historically occupied large, isolated lakes and wetlands in northern Wisconsin, but there were no known nesting sites until 1919, when cormorants were reported nesting on Lake Wisconsin in south-central Wisconsin. From the 1920’s to the 1950’s, cormorants occupied 17 colony sites in 16 counties, though no more than 7 sites were occupied during any particular year. From the 1950’s to the early 1970’s, the number of cormorant nests …

Impact Of Double-Crested Cormorant Predation On The Yellow Perch Population In The Les Cheneaux Islands Of Michigan, Glenn Y. Belyea, Susan L. Maruca, James S. Diana, Philip J. Schneeberger, Steve J. Scott, Richard D. Clark Jr., James P. Ludwig, Cheryl L. Summer

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

The Michigan Department of Natural Resources, in conjunction with the University of Michigan and the U.S. Fish and Wildlife Service, initiated a research study to determine the impact of double-crested cormorants (Phalacrocorax auritus) on the yellow perch (Perca flavescens) population in the Les Cheneaux Islands area of northern Lake Huron. Aerial and nesting colony counts were conducted to monitor cormorant abundance. Creel census counts and tagging of 8,400 perch were used to study perch abundance. We collected 373 cormorants to study food habits via stomach-content analysis. We found that (1) cormorants fed heavily on yellow perch …

Fish Losses To Double-Crested Cormorant Predation In Eastern Lake Ontario, 1992–97, Robert M. Ross, James H. Johnson

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

We examined 4,848 regurgitated digestive pellets of double-crested cormorants (Phalacrocorax auritus) over a 6-year period (1992–97) to estimate annual predation on sport and other fishes in the eastern basin of Lake Ontario. We found more than 51,000 fish of 28 species. Using a model that incorporates annual colony nest counts; fledgling production rates; adult, immature, and young-of-year residence times (seasonal); estimates of mean number of fish per pellet and mean fish size; and a fecal pathway correction factor (4.0 percent), we estimate total annual number of fish consumed by cormorants in the eastern basin of Lake Ontario to …

Possible Effects Of Catfish Exploitation On Overwinter Body Condition Of Double-Crested Cormorants, James F. Glahn, Mark E. Tobin, J. Brent Harrel

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Concurrent with the rapid growth of the Mississippi catfish industry during the 1980’s, there was evidence of similar growth of double-crested cormorant (Phalacrocorax auritus) populations wintering in the delta region of Mississippi. Observational and food habits studies indicate that this expansive industry, incorporating more than 100,000 acres of ponds, provides an enormous food base for overwintering populations estimated in recent years to exceed 50,000 birds. As much as 75 percent of the diet in certain roosting areas of the Mississippi delta consisted of catfish, and according to bioenergetic models cormorants can exploit as much as 940 metric tons …

Review Of The Population Status And Management Of Double-Crested Cormorants In Ontario, C. Korfanty, W.G. Miyasaki, J.L. Harcus

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

We prepared this review of the status and management of double-crested cormorants (Phalacrocorax auritus) in Ontario, with management options, in response to concerns expressed about possible negative impacts of large numbers of the birds on fish stocks, and vulnerable, threatened and endangered species. Double-crested cormorants are native to Ontario and were first recorded breeding on Lake of the Woods in northwestern Ontario in the late 1700’s. The birds spread eastward to colonize all of the Great Lakes by the 1930’s. A decline in cormorant populations on the Great Lakes from the 1950’s to the 1970’s has been attributed …

The Female Identity In Rosario Ferré'S Papeles De Pandora, Marcie Lynn Pratt

Dissertations and Theses

This thesis examines four stories from Rosario Ferré's first book of short stories, Papeles de Pandora: "La muñeca menor," "Cuando las mujeres quieren a los hombres," "Amalia," and "La bella durmiente." In Papeles de Pandora, Ferré explores the portrayal of female identity by dismantling the traditional roles that are assigned to women in Puerto Rican, patriarchal society. This thesis analyzes the ways in which Ferré skillfully deconstructs and (re)constructs the identity and sense of self of her female protagonists.

To demonstrate Ferré's deconstruction and (re)construction of the female identity, this study focuses on Ferré's use of recurring motifs …

Probing The Intermolecular Hydrogen Bonding Of Water Molecules At The Ccl4/Water Interface In The Presence Of Charges Soluble Surfactant, D. E. Gragson, G. L. Richmond

Chemistry and Biochemistry

The molecular structure and hydrogen bonding of water molecules at the CCl₄/water interface in the presence of a charged soluble surfactant has been explored in this study using vibrational sum frequency generation. By examining OH stretching modes that are highly sensitive to the local hydrogen bonding environment it is found that water molecules at the CCl₄/water interface both in the presence and absence of a charged soluble surfactant are predominantly in a tetrahedral arrangement much like the structure ofice. Isotopic dilution studies have been employed to further characterize this icelike interfacial structure. Ablueshift ofapproximately120 cm^{-1 …}
