Wolves not gnawing into Island’s prey population – Victoria News

 

A recent wolf sighting in Campbell River raised questions about the animal’s conservation status on Vancouver Island, and whether wolves are responsible for reduced numbers of animals including deer and marmots.

Chris Darimont, a leading wolf expert and Raincoast Research Chair at the University of Victoria, says there’s no immediate threat to wolf populations on Vancouver Island, and forestry practices, not wolf populations, are to blame for a decline in animals such as deer.

“They’re a convenient scapegoat,” Darimont said in an interview. “But decades of research… reveal very little evidence that wolves cause declines in prey populations.”

1084M was a Thorofare wolf | Local | jhnewsandguide.com

 

Wolf 1084MAs recently as last fall, the animal that’s making headlines as the first Colorado wolf in four years was wandering one of the most remote and wild landscapes left in the Lower 48 states.

It was the closing days of October when a pilot contracted by the Wyoming Game and Fish Department pinged 1084M with his Snake River Pack mates in the willow complex not far from Hawk’s Rest, a craggy mountain overlooking the Upper Yellowstone River that’s famous for its location — as far as one can get from a road in the Lower 48.

The 3-year-old black male lobo with a still-functional tracking collar then headed east over the vast, rugged Absaroka Range, entering the winter in the South Fork of the Shoshone River drainage.

Six new wolf pups born in Mount Hood area of Western Oregon

Six new wolf pups were born to the White River Pack this year, according to footage from a trail cam put up by biologists with the Confederated Tribes of Warm Springs and shared by the U.S. Fish and Wildlife Service.

The White River Pack is located just southeast of Mount Hood and east of popular Timothy Lake. With five members in 2018, it was one of the few confirmed packs in Western Oregon, along with southwest Oregon’s Rogue Pack.

Inslee Breaks With State Officials, Opposes Removing Protections for Gray Wolf

CN) – Washington Governor Jay Inslee revealed his opposition Wednesday to the Trump administration’s plan to remove gray wolves from the federal Endangered Species List – contradicting the position of the state’s Fish & Wildlife director, who also Wednesday announced the state will kill two federally protected wolves because they hunted cattle grazing on public land.

“Governor Inslee does not support a nationwide proposal that delists gray wolves from the federal endangered species list in all of the lower 48 states because there are many areas where wolves have not yet been recovered,” Inslee spokeswoman Jessie Payne said in an email (bold in original).

Je volk nevaren človeku ali človek volku?

slika

Kljub temu obstajajo določene, sicer izjemno redke okoliščine, v katerih pa bi tudi volk lahko postal nevaren za človeka. Glavni razlog za to je steklina. Podobno kot druge živali in ljudje tudi volkovi, ki so oboleli za steklino, spremenijo svoje vedenje in postanejo agresivni do vseh drugih bitij.

Steklina pri volkovih v Sloveniji sicer do zdaj še ni bil odkrita. Druga možnost nevarnosti so križanci med psi in volkovi. Križanci v primerjavi z volkovi pogosto nimajo prirojenega strahu pred ljudmi in zato večkrat prihajajo v stik s človekom. Za večino tistih nekaj znanih primerov, ko je volk napadel človeka in so o tem poročali iz tujine, je bila kriva steklina ali pa križanci s psi.

Pup fostering gives genetic boost to wild Mexican wolves

ALBUQUERQUE – It’s a carefully planned mission that involves coordination across state lines – from Mexican gray wolf dens hidden deep in the woods of New Mexico and Arizona to breeding facilities at zoos and special conservation centers around the U.S.

It’s also about timing, as wolves in the wild and those in captivity need to be having pups at the same time to ensure a smooth transition.

Pups born within a couple days of each other are the best candidates for a fostering program that aims to get more pups out of captivity and into the wild in hopes of boosting the genetic diversity of the endangered species.

Comparative analysis of peripheral blood reveals transcriptomic adaptations to extreme environments on the Qinghai-Tibetan Plateau in the gray wolf ( Canis lupus chanco) | SpringerLink

Abstract

Molecular adaptations to life on the Qinghai-Tibetan Plateau (QTP) have been detected in the genomes of many native animals, but the contribution of variations in gene expression to high-altitude adaptation remains to be determined. Here, we sequenced the peripheral blood transcriptomes of the lowland wolf and the Tibetan wolf (Canis lupus chanco), an endemic top predator on the QTP, and analyzed how the gene expression pattern has become modified to cope with the extreme plateau environments. Comparisons of the transcriptomes of Tibetan wolves and their lowland counterparts revealed 90 differentially expressed genes (DEGs), including 6 genes (ATP6, ATP8, COX3, CYTB, ND2, and ND4) located in the mitochondrial respiratory chain. Several DEGs are functionally involved in DNA repair (RAD52 and NUPR1), reactive oxygen species (ROS) regulation (GSTP1 and RETSAT), and cardiovascular homeostasis (ACTA2, CD151, DDX6, HPSE, and YOD1). Further functional enrichment analyses demonstrated that the identified DEGs were significantly enriched in specific functional categories related to energy metabolism, hypoxic response, and cardiovascular homeostasis, indicating that the gene expression variation in Tibetan wolves may contribute to their adaptation to life on the QTP. The phylogenetic topology of worldwide populations based on 12 mitochondrial protein-coding genes (MPGs) is inconsistent with the patterns revealed by a previous genome-wide study, implying that adaptive evolution may have occurred in the MPGs of Tibetan wolves. Wolf ATP8 was shown to have a higher dN/dS (ω) ratio (ω = 0.712) than the other 11 genes (ω ≤ 0.272). Overall, our study provides new insights into the mechanisms underlying high-altitude adaptations in a wild carnivore with not only mitochondrial gene adaptation but also fine-tuned gene expression responses.
