Estimation Of Harvest Rate And Vulnerability From Age And Sex Data, J. E. Pahoheimo, David Fraser Oct 1981

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 Role And Responsibility Of Zoos: An Animal Protection Viewpoint, John E. Cooper Jan 1981

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.


An Overview Of Zoo Goals And Exhibition Principles, Randall L. Eaton Jan 1981

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 Coyote (Canis Latrans) In Panama, Eustorgio Méndez, Francisco Delgádo, Demetrio Miranda Jan 1981

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.


Injuries To Birds Of Prey Caught In Leghold Traps, Katherine Durham Jan 1981

Injuries To Birds Of Prey Caught In Leghold Traps, Katherine Durham

Conservation Collection

173 birds of prey, including 32 Bald Eagles, have been treated for trapping injuries at the University of Minnesota Raptor Research and Rehabilitation Program since 1972. These were birds caught primarily in "open" bait /eghold sets incidental to furbearer trapping in the Minnesota region. The differential outcome of the injuries with respect to crippling or mortality is presented for large versus small raptors, toe versus leg injuries, and fracture of the leg versus soft tissue damage only.

There is only limited potential for mitigating the effects of trapping injuries to raptors because of the irreversible soft tissue damage usually associated …


Getting Educated At The Zoo, Nancy Heneson Jan 1981

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.
