Wolf Social Ecology, L. David Mech, Luigi Boitani

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

THE FIRST REAL BEGINNING to our understanding of wolf social ecology came from wolf 2204 on 23 May 1972. State depredation control trapper Lawrence Waino, of Duluth, Minnesota, had caught this female wolf 112 km ( 67 mi) south of where L. D. Mech had radio-collared her in the Superior National Forest 2 years earlier. A young lone wolf, nomadic over 100 km² (40 mi²) during the 9 months Mech had been able to keep track of her, she had then disappeared until Waino caught her. From her nipples it was apparent that she had just been …

Wolves And Humans, Steven H. Fritts, Robert O. Stephenson, Robert D. Hayes, Luigi Boitani

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

TRY TO IMAGINE a small group of wolves sitting at a table engaged in vigorous debate. These wolves are from various parts of the globe and are perhaps a bit more scholarly than most. In fact, they are especially knowledgeable about the biology of that notorious two-legged species, Homo sapiens. They have been brought together to document their relationship with humans over the last several millennia. Pause for a few moments and consider what they might say ...

Perhaps the wolves' discussion would chronicle the evils of the human species, including details of atrocities committed against lupine ancestors down …

Wolf Interactions With Non-Prey, Warren B. Ballard, Ludwig N. Carbyn, Douglas W. Smith

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

WOLVES SHARE THEIR ENVIRONMENT with many animals besides those that they prey on, and the nature of the interactions between wolves and these other creatures varies considerably. Some of these sympatric animals are fellow canids such as foxes, coyotes, and jackals. Others are large carnivores such as bears and cougars. In addition, ravens, eagles, wolverines, and a host of other birds and mammals interact with wolves, if only by feeding on the remains of their kills.

Conclusion, L. David Mech, Luigi Boitani

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

WOLVES CAN LIVE almost anywhere in the Northern Hemisphere, and almost everywhere they do, they are an issue. In the vast emptiness of the northern tundra or the Arabian desert, on the outskirts of a European town or in the safety of an American national park, in meager agricultural lands in India or mountains in rich Norway or Switzerland, wolves always attract people's attention. Wolves form a key part of many ecosystems, and they are considered charismatic creatures by most human cultures. Thus they polarize public opinion and make headlines year after year.

If we look back 6o years to …

Survival Of The Western Pond Turtle (Emys Marmorata) In An Urban California Environment, Phillip Q. Spinks, Gregory B. Pauly, John J. Crayon, H. Bradley Shaffer

United States Geological Survey: Staff Publications

The western pond turtle Emys (formerly Clemmys marmorata) is declining throughout its range, primarily due to loss of habitat via urbanization and conversion to agriculture. Urban waterways present several important challenges to freshwater turtle populations, but they also present an opportunity to maintain declining species in a ubiquitous habitat that has high public visibility. The arboretum waterway on the University of California, Davis campus is an example of an extensively altered urban habitat that supports a relatively large E. marmorata population. Over the last 6 years, we monitored the turtle population inhabiting the arboretum waterway to determine the …

The specific activity of the purified enzyme was found about 150 times greater than that of the crude rumen homogenate. The molecular weight of native arginase, estimated by gel filtration on a Sephadex G-150 column, was 122 500 ± 2500 and those of subunits of the enzyme, estimated by SDS-PAGE and gel filtration on a Sephadex G-100 column, were 44 000 ± 1000 and 34 500 ± 500. This indicates that the native enzyme is a trimer …

Effects Of Cadmium On Uterine Contractions In Different Species In Vitro, Haki̇ Kara, Kadi̇r Servi̇, Yaşar Akar

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to examine the effects of cadmium on oxytocin-induced myometrium contractions in rats, cows and cats in vitro. The frequency was 12.20 ± 1.2, 11.25 ± 2.7 and 10.70 ± 2.5/10 min, respectively, after 0.01 mM oxytocin induced with myometrial samples in rats, cows and cats. The peak amplitude was 3.84 ± 0.50, 3.44 ± 0.65 and 3.35 ± 0.45 g, respectively, after oxytocin induction. The frequency and peak amplitude decreased after the addition of 0.01 mM cadmium chloride (CdCl_2). The frequency was 1.2 ± 0.4 (p < 0.001), 2.5 ± 0.5 (p < 0.001) and 2.0 ± 0.6(p < 0.001), respectively, and the peak amplitude was 0.7 ± 0.3 (p < 0.001), 1.2 ± 0.2 (p < 0.001) and 0.8 ± 0.4 g (p < 0.001), respectively, in rat, cow and cat myometrium. Finally, the myometrium contractions were completely inhibited in the three species. In conclusion, the effects of cadmium may inhibit both calcium channels and the intracellular-induced mechanism.
