NABU fordert Kompetenzstelle für den Wolfs-Schutz

In Deutschland sind innerhalb nur einer Woche drei Wölfe zu Tode gekommen. Nachdem am vergangenen Freitag ein Wolf illegal in der sächsischen Lausitz geschossen wurde, starben zwei weitere Anfang dieser Woche durch Verkehrsunfälle: Bereits am Montag wurde ein Wolf auf einer Bundesstraße im nördlichen Sachsen-Anhalt überfahren, einen weiteren erwischte auf dem Berliner Ring in Brandenburg. Menschen kamen dabei nicht zu Schaden. Zuletzt war am 16. November ein Wolf bei einem Verkehrsunfall getötet worden – fast an identischer Stelle wie das Tier in Sachsen-Anhalt am Montag. (more…)

UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.

The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.

The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population. (more…)

Thermal Imagery Sheds Light on Wolf Disease

Psychedelically colored wolves depicted by thermal imaging will shed light on how mange affects the survival, reproduction and social behavior of wolves in Yellowstone National Park.

About a quarter of the wolf packs in the park are afflicted with sarcoptic mange, a highly contagious canine skin disease caused by mites that burrow into the skin causing infections, hair loss, severe irritation and an insatiable desire to scratch.

The resulting hair loss and depressed vigor of the wolves leaves them vulnerable to hypothermia, malnutrition and dehydration, which can eventually lead to death, said Paul Cross, a U.S. Geological Survey disease ecologist, who leads the project along with Doug Smith of Yellowstone National Park.
