Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen

Ecology Collection

During the nineteenth century, the large predators of Finland- wolf, bear, lynx, and wolverine- were exterminated in the southern and western regions of the country. There were almost no lynx by the late 1950s, but a protection order issued in 1968 has resulted in a steady increase in their number, to about 300 by 1980. There was a breeding population of wolverines until the late 1960s, but in the 1970s, most were killed by snowmobiles, and only 10-30 are now thought to inhabit the frontiers between Finland and the USSR, and Finland and Norway. Bears, in the 1970s, tended to …

Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert

Nature Collection

Although there is a diversity of opinion about how to view the relationship between humans and wildlife, recent political pressures from the current administration make it mandatory that these diverse groups coalesce to use their combined leverage to halt the planned incursions into the remaining habitats of wildlife. It is also important to begin to see nature as a complex and interrelated whole, and to respect the integrity of that whole, rather than simply select individual species for affection and protection.

Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau

Laws and Legislation Collection

This paper provides a framework for understanding the Government's position on many wildlife topics, including humane ethics. The historical role of Government in wildlife conservation is traced in relation to pertinent theories of bureaucracy. It is shown that Government involvement in wildlife conservation increased through successive stages of change because of interest group activity.

These periods of increased Government involvement in wildlife matters are shown to have followed periods of resource exploitation. Recurrent cycles of exploitation, accompanied by economic prosperity, have then been followed by attitudes favorable to conservation and political activism. This, in turn, has produced periods of backlash …

Urban Wildlife Habitat -- Present And Future, David Tylka

Ecology Collection

Many kinds of wild animals can become adapted to living in cities, provided that the right kinds of habitats are available and that their presence is accepted by city-dwellers. Suitable habitats can be furnished by traditional parks, tracts of "wild acres" set aside by cities, linear parks, cemeteries and golf courses, and transportation corridors. Buildings, rooftops, and institutional grounds can also provide habitat for animals like birds and butterfiles. Suburban areas can encourage the growth of local wildlife by neglecting to mow common grounds, or allowing sections of individual lawns to grow up with wild vegetation.

Ethical Issues And Future Directions In Wildlife Management, John W. Grandy

Nature Collection

Recent progress in protection of wildlife and wildlife refuges is currently being undermined by the efforts of James Watt, U.S. Secretary of the Interior, who believes that commercial interests should take precedence over the preservation of pristine wilderness areas and wildlife sanctuaries. The consequent loss, as populations approach extinction because of programs like decimation of habitats and predator control, is more than simply aesthetic: genetic material unique to each species will be lost forever. Particular issues of immediate concern are the fate of bobcats and whales, inhumane trapping, and the Endangered Species Act. As a longer-term concern, the goal of …

Introduced Species And The Issue Of Animal Welfare, Michael Hutchins, Victoria Stevens, Natasha Atkins

Ecology Collection

Recently, considerable debate has been heard about the control or elimination of introduced or "exotic" animals on publicly held U.S. lands. Species introductions, whether intentional or unintentional, seem to be an inevitable result of human activities, but they may result in both economic and ecological problems: It has been estimated that over 90 percent of all such introductions have been harmful in some respect. Control of exotics can be accomplished through containment, shooting, poisoning, reintroduction of native predators, introduction of disease organisms, live capture and removal, and reproductive inhibition.

Those who must make decisions about the fate of introduced species …

Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser

Wildlife Population Management Collection

A nonlinear least-squares procedure is developed to estimate harvest rate and differential vulnerability in wildlife populations that are harvested with 1 segment of the population more able than another. The method requires age data by category from a series of harvests, plus information on accumulated harvest effort, and assumes that the nonharvest mortality rate is the same for the categories. The data need not be from consecutive harvests, as long as the effort is known for missing Monte Carlo simulations were done to verify the estimation procedure. An example shows the application of the method to moose (Alces alces) harvest …

The Coyote (Canis Latrans) In Panama, Eustorgio Méndez, Francisco Delgádo, Demetrio Miranda

Conservation Collection

This report reveals that the coyote, Canis Iatrans, has recently extended its southern range to Panama. The skin of one adult female coyote killed by hunters at Los Pirales, a farm near Gualaca in Chiriqui Province, western Panama, has been deposited in the Gorgas Memorial Laboratory Vertebrate Collection. Other coyotes have been observed in Alanje, Boquete and Boqueron, other localities of the same province. The probable range of the coyote in Panama is indicated, and the need for an urgent management strategy for this canid in the Republic is also expressed.

Getting Educated At The Zoo, Nancy Heneson

Zoos and Aquariums Collection

In this issue we present three papers that deal with the subject of the zoo. Although the focal concern of each paper is different and the positions of the authors range from whole-hearted support of the institution to frank skepticism, all express a belief in the potential educational value of zoos. This editorial, however, has a different premise. It is not meant to criticize the other papers, but rather to raise questions from another point of view.

An Overview Of Zoo Goals And Exhibition Principles, Randall L. Eaton

Zoos and Aquariums Collection

It is not uncommon among progressive-minded zoo professionals these days to hear disdain for the function of zoos as recreational. This attitude is understandable in that traditionally, zoos have done little but offer amusement along with parklands or picnic facilities. The progressive zoo person sets his or her goals above the old-fashioned recipe of crowding as many exotic animals as possible into an amusement-oriented menagerie to an authentic theme for exhibition intended to educate the public, offer research possibilities, and preserve and propagate species. Nevertheless, recreation remains a primary function of zoos. Most zoo visitors do not seek education in …

The Role And Responsibility Of Zoos: An Animal Protection Viewpoint, John E. Cooper

Zoos and Aquariums Collection

The aim of this paper is to look at zoological collections from the viewpoint of the animal and, in particular, to draw attention to areas where welfare considerations should be paramount. I do not intend to cover the capture and transportation of zoo animals, although this is obviously of great importance and must be included in any overall consideration of the welfare of zoo animals. In this paper, however, I shall concentrate upon the care of the animal within the zoo environment.

Roadside Zoos Are Not Zoos

Close Up Reports

The HSUS was one of the first national animal welfare organizations to take a long, hard look at all zoos, including roadside menageries. During the last nine years, we have worked intensively, conducting zoo inspections, public education and awareness programs, and developing a working relationship with the professional zoological community as well as U.S. Government agencies charged with the welfare of animals.

Bringing Nature Into The Zoo: Inexpensive Solutions For Zoo Environments, David Hancocks

Zoos and Aquariums Collection

Animals in captivity have traditionally been kept in sterile and inappropriate environments. Typically this situation still prevails in zoos. Cages are designed only for restraint of the animals, expediency for the public, and convenient maintenance by keepers. The animals' behavioral needs are often ignored. By using nature as a norm, and by using natural materials, the spatial and temporal environment of a captive animal can be easily and greatly enriched. Several examples which have been used at Woodland Park Zoological Gardens are discussed. Their application and expansion are appropriate for most urban zoos.

Homeless Cats And Dogs Are Suffering And Dying

Close Up Reports

Last year more than 13 million homeless cats and dogs were euthanized at humane societies and municipal animal shelters. As a statistic, 13 million may be meaningless. But think of it another way. Think of the 13 million as individual animals with individual personalities--each with their own beating heart, each with their own wretched story of how they found their way to the animal shelter. Each one was an individual breathing creature whose life was ended because there was no home to go to.
