Zusammenfassung
Vorliegender Beitrag gibt einen überblick über die floristische Durchforschung der MVR.
Erste Kenntnisse über die Flora der Mongolei stammen aus dem 18. Jh. und der ersten Hälfte des 19. Jh. (MESSERSCHMIDT, BUNGE, MAXIMOVICZ). In der zweiten Hälfte und am Ende des 19. Jh. erbrachten vor allem die Expeditionen der Russischen Geographischen Gesellschaft umfangreiches botanisches Material (POTANIN, KOZLOV). Auch andere Forscher führten ausgedehnte Sammelreisen durcn (KLEMENZ, PALIBIN, SAPOZNIKOV). Nach der mongolischen Revolution von 1921 wurden von sowjetischer Seite bereits in den 20er Jahren Sammelreisen durchgeführt. 1925 wurde die Mongolische Kommission der Akademie der Wissenschaften der UdSSR geschaffen, die weitere Expeditionen …

Federal Government Assaults Animals On Wildlife Refuges
Federal Government Assaults Animals On Wildlife Refuges
Close Up Reports
The welfare of America's wildlife and refuges is being sold for economic gain and recreational pleasure to hunters, trappers, and commercial developers. To date, there are 414 refuges composed of over 86 million acres stretching from the Arctic to the Florida Keys and from Maine to American Samoa. Almost all of these refuges have been touched in some way by natural gas exploration, predator control, pesticides, and commercial farming, ranching, and lumber industries. Over one half of all refuges are open to either hunting or trapping...or both.
All laws and regulations concerning activities on wildlife refuges stipulate that there must …
Solving The Pet Overpopulation Problem
Solving The Pet Overpopulation Problem
Close Up Reports
Because of the short pregnancies and large litters of dogs and cats, one individual female with all her female offspring reproducing similarly can be the source of over 4,000 new lives within seven years. Some of these animals will find homes complete with laps to sit on and fireplaces to enjoy, but millions of other perfectly healthy dogs and cats won't be so lucky. The overabundance of these potential pets tends to cheapen the intrinsic value of each individual animal in the eyes of the general public. The swelling problem causes some people to use cruel methods of disposing of …

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
Nature Collection
In this study, three indirect methods [counts of animal droppings, footprints, and tracks) were used as indices to estimate the abundance and distribution of large mammals in the Upper Ogun Game Reserve, which is located in a typical Southern Guinea savanna zone of Nigeria. Thirteen animal species were recorded; kob, bushbuck, hartebeest, roan antelope and duicker were the most abundant. The distribution of large mammals appears to be controlled by several factors: accessibility to the River Ogun [the main source of water in the reserve), availability of food and cover, and the extent of illegal hunting.
An analysis of questionnaires …
Feral Dogs Of The Galapágos Islands: Impact And Control, Bruce D. Barnett, Robert L. Rudd
Feral Dogs Of The Galapágos Islands: Impact And Control, Bruce D. Barnett, Robert L. Rudd
Ecology Collection
Organisms introduced onto insular ecosystems, after they have become established, frequently increase to destructive numbers. Several species of mammals introduced onto the Galapagos Islands illustrate this ecological axiom. For example, domestic dogs intentionally introduced now exist as three major types: domestic, free--ranging or pariah, and feral. Problems derived from their presence are most apparent on the islands of Santa Cruz and lsabela. Feral and pariah dogs are both scavengers and predators. While other introduced mammals (chiefly feral cattle and pigs) have served as prey, in recent years severe depredations on the unique endemic Ga/apagan fauna have been caused by the …

Stray-Dog Control In Cyprus: Primitive And Humane Methods, Kyriacos Polydorou
Hunting Collection
In Cyprus, a dog control scheme was started in 1971 within the context of an all-inclusive anti-echinococcosis campaign. At the time, it was estimated that there were more than 100,000 dogs in the island, almost all of which were strays (even many of those that were purportedly "owned"]. These had been identified as infectious agents of echinococcosis in Cyprus (the average surgical incidence in humans, over the 30-year period prior to 1970, was 12.9/100,000]. The destruction of stray dogs is accomplished by using guns that fire a syringe containing a euthanizing drug. In the past (prior to 1970), various inhumane …

Whaling Ban Threatened
Close Up Reports
A handful of countries, serving only their own greedy self-interests at the expense of the world's few remaining great whales, are threatening to sabotage the only hope of survival left to these magnificent creatures. Japan, the U.S.S.R., Norway, and Peru have filed formal objections with the International Whaling Commission (IWC) to that body's landmark decision to ban commercial whaling as of 1986. Iceland, Brazil, and South Korea, the world's other whaling nations, may join this infamous quartet and add their own objections before the filing deadline in 1983. Unless animal-welfare proponents act decisively now, years of negotiation and scientific inquiry--and …

U.S. Declares War On Coyotes
Close Up Reports
The coyote has long been perceived as a threat by ranchers who graze their sheep on U.S. public lands. At the ranchers' insistence, U.S. government employees are paid to shoot coyotes from helicopters and airplanes, ambush them in cruel steel-jaw leghold traps, and plant cyanide guns that explode in the coyotes' faces. The Humane Society of the United States is irrevocably opposed to the unabated, cruel, and unnecessary practice of killing animals in the name of "predator control." The resumed use of denning and the threat of reinstituting 1080 makes our--and your--actions even more urgent.

Experiences In The Protection Of The Large Predators In Finland, Erkki Pulliainen
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
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
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
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 …
Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser
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.

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.

First paragraph:
Die Landschaften der Mongolei sind arm an Reptilien- und Amphibienarten. Dieser Umstand mag die Frage aufwerfen, ob herpetologische Untersuchungen in Beschränkung auf das Territorium der MVR eine nennenswerte Perspektive haben könnten, nachdem Artenspektrum und Verbteitung der Species annähernd vollständig erkundet sind. Ein Herpetologe wird zweifellos für seine Arbeit auch in diesem Land eine Zukunft sehen, doch muß wohl von vornherein eingestanden werden, daß das Volumen der Probleme dieses Faches hinter denen der übrigen Disziplinen der Vertebratenzoologie und der Entomologie in einem bescheidenerem Rahmen verbleibt.

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.
