Abundance And Distribution Of Large Mammals In The Upper Ogun Game Reserve, Oyo State, Nigeria, T. A. Afolayan, K. R. N. Milligan, S. O. Salami
Abundance And Distribution Of Large Mammals In The Upper Ogun Game Reserve, Oyo State, Nigeria, T. A. Afolayan, K. R. N. Milligan, S. O. Salami
International Journal for the Study of Animal Problems
Three different methods for estimating wild animal populations were used to assess the density of different species in a game reserve in the Sahel region of Nigeria. Hunting for bushmeat by local communities living around the reserve was identified as one of the threats to wildlife populations. Bushmeat was an essential resource for communities around the reserve.
The North American Black Duck (Anas Rubriges): A Case Study Of 28 Years Of Failure In American Wildlife Management, John W. Grandy
The North American Black Duck (Anas Rubriges): A Case Study Of 28 Years Of Failure In American Wildlife Management, John W. Grandy
International Journal for the Study of Animal Problems
A scientific and technical analysis is presented of the factors that may have been responsible for an estimated 60% decline in the black duck (Anas rubripes) population since 1955. The analyses presented show that the U.S. Fish and Wildlife Service (FWS], the management agency responsible for waterfowl management in the United States, has recognized the population decline, that the FWS's own experts have consistently recognized that hunting is the most likely cause of the population decline and that hunting is the only mortality factor which wildlife managers can control in the practical sense. Using FWS information, the author …
Biological Control Of Aleutian Island Arctic Fox: A Preliminary Strategy, Edward W. West, Robert L. Rudd
Biological Control Of Aleutian Island Arctic Fox: A Preliminary Strategy, Edward W. West, Robert L. Rudd
International Journal for the Study of Animal Problems
The intentional introduction of exotic animals can generally be expected to yield unanticipated biological consequences. Single-purpose introductions frequently result in ecological catastrophe. Islands are particularly vulnerable to such assault. Arctic foxes [Alopex lagopus), released for fur farming on the Aleutian Islands, formerly devoid of land predators, have significantly altered nesting avifaunal diversity, abundance, and productivity. A program for restoring the historical distribution and abundance of critically affected bird species is described. In a long-term study, biological control methods are proposed to test the hypothesis that introduced sterile red foxes [Vulpes fulva), apparently, a competitively superior species, will markedly …

Letter To Editor: Turtle Excluder Device, James Sternberg
International Journal for the Study of Animal Problems
The author comments on a previous article describing devices (excluder devices) that protect sea turtles during shrimping operations and corrects a few errors.
Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen
Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen
International Journal for the Study of Animal Problems
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 late 1950. However, a protection order issued in 1968 resulted in a steady increase in their number, to about 300 by 1980. A breeding wolverine population existed until the late 1960s. In the 1970s, most were killed by snowmobiles. It is now thought only 10-30 inhabit the frontiers between Finland and the USSR and Finland and Norway. Bears, in the 1970s, tended to immigrate to Finland from the east; …
Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert
Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert
International Journal for the Study of Animal Problems
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 essential to begin to see nature as a complex and interrelated whole and to respect the integrity of that whole rather than select individual species for affection and protection.
Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau
Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau
International Journal for the Study of Animal Problems
This paper provides a framework for understanding the Government's position on many wildlife topics, including humane ethics. The Government's historical role in wildlife conservation is traced 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.
Ethical Issues And Future Directions In Wildlife Management, John W. Grandy
Ethical Issues And Future Directions In Wildlife Management, John W. Grandy
International Journal for the Study of Animal Problems
Recent progress in the 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. As populations approach extinction because of programs like decimation of habitats and predator control, the consequent loss 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, wildlife management's …
The Leopard In Africa: Biological And Cultural Realities, Norman Myers
The Leopard In Africa: Biological And Cultural Realities, Norman Myers
International Journal for the Study of Animal Problems
The author comments on a proposal to change the leopard's status in Africa from endangered to threatened, which would open the leopard up to sport hunting. This proposed change would be a mistake, in the author's opinion. While the leopard still occurs in satisfactory numbers in some countries despite being rarely seen, its population is much lower than it could in other countries. The author notes that the real problem is not the species' biological status but the institutional, socio-cultural, and economic considerations. Wildlife conservation in Africa is challenging enough without the further complications that sport hunting brings.
The Coyote (Canis Latrans) In Panama, Eustorgio Mendez, Francisco Delgado, Demetrio Miranda
The Coyote (Canis Latrans) In Panama, Eustorgio Mendez, Francisco Delgado, Demetrio Miranda
International Journal for the Study of Animal Problems
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. In the same province, other coyotes have been observed in Alanje, Boquete, and Boqueron. The probable coyote range in Panama is indicated, and the need for an urgent management strategy for this canid in the Republic is also expressed.
