 Every Yellowstone Wolf Pack Numbers at Year End [Data collected from the Yellowstone Wolf Project Annual Reports 1995-2019]
Note : Only Wolf Packs in the park were showcase. Some of these packs like Swan Lake, Chief Joseph & A few more moved outside the park at one point.
It also doesn't explain why some packs suddenly vanished [Leopold Pack were 19 in December 2007 but 0 in December 2008. The dominant breeding pair died & the pups all died from suspected & highly probable canine distemper virus outbreak [The third outbreak of this disease since wolf reintroduction]
Mange weakened multiple packs from 2007 to 2012 including the Silver Pack [Not even in these graphs], The Everts Packs & The Legendary Druid Pack amongst others.
Made by myself on December 2nd 2020. Edit : I accidentally placed the 2019 graph before the 2018 lol. Oops.[Christophe Boucher/TNG]

Audio Files :
- Wikipédia User "Retron" who recorded European wolves "rallying" in July 2005.
- U.S. Fish & Wildlife Service who recorded a pack howling on July 1, 2005.
Here one quite rare video in which can be seen two wolves and reaction, when at 0:50 wolves from distance start to howl, also response from these wolves is there. First one and then other joins too (1:58-1:59). From Finland, October 2020.
Sound up!
In this video wolves of Ähtäri zoo are howling. Reason is unknown. They howled first a bit and then after a pause started again with more voice. This zoo is in the middle of the forests, maybe they heard their wild relatives in the distance distance even though people couldn´t.

A “legendary” female wolf known for birthing 40 pups in the past decade has suddenly reappeared in the wild after falling off tracking in 2018, according to the U.S. Fish and Wildlife Service. FACEBOOK SCREENSHOT [/color] A “legendary” female wolf known for birthing dozens of pups has mysteriously resurfaced in Arizona after vanishing in 2018, according to the U.S. Fish and Wildlife Service. Known only as #1042F, the Mexican wolf has survived in the wild for 14 years — nearly double the life expectancy of her species — including nine years as an “alpha female,” wildlife officials posted Monday on Facebook. During that period, 1042 produced 40 pups, “the most wolf pups of any wolf in the U.S. Mexico wolf population,” the federal wildlife agency said. Mexican wolves are “the rarest subspecies of gray wolf in North America,” with a propensity for “numerous vocalizations” and a knack for bringing down prey “much larger” than their 50- to 80-pound frame, wildlife experts say. hey live six to eight years on average, according to the Center for Biological Diversity. Wolf 1042 was born in 2006 in Arizona’s Apache National Forest and became an “alpha female” three years later, officials say. The forest is 2 million acres of “magnificent mountain country in east-central Arizona,” Stateparks.com reports. The wolf “remained the alpha female of the Bluestem pack until 2018, when biologists could no longer locate her,” wildlife officials said. Why she vanished and where she went is unknown, but 1042 resurfaced Nov. 15, appearing on a trail camera “roaming around her old home range,” officials said. She appeared healthy but had a clearly visible injury to her left ear “likely from hunting or during a conflict with another wolf.” Quote:Of her 40 pups,16 “went on to become breeding wolves in packs of their own. As of 2020, eight of her offspring remain breeding alpha wolves in the current population,” officials said. Personal Note [By me] : She is a legend ! And i love her so much. To say that she was alive when i was 6 years old & Im 20 now is quite an extraordinary feat. It also makes her older than Idaho Wolf #B2M, who died at the age of 13 years & 3/4. Absolutely fantastic Mexican Wolf !
The wolf howling is really impressive!
In 2016, I've spend a night in Mahikan Park in Quebec. It's a wolf Park at the North of the St-Jean Lake. You sleep in a bungalow between 3 wolves parks (polars, grey and impregnated wolves) https://youtu.be/U-hmXDAi-Sw (01-13-2021, 01:13 AM)PolarBear Wrote: The wolf howling is really impressive! Intéressant, j'irai peut-être un jour haha Interesting, i'lle likely go someday. I live in Quebec. Composition of Yellowstone Wolves Kills (1995-2019)
Wolf immigration doesn’t compensate for losses from hunting
For wolf packs in Idaho and Alberta, immigration from other areas doesn’t compensate for their losses. “There was very little immigration, even though harvest was removing individuals,” said Sarah Bassing, PhD candidate in environmental and forest sciences at the University of Washington and the lead author of the study published recently in Animal Conservation. Bassing said that wildlife managers have long assumed that when gray wolves (Canis lupus) are harvested in one region, new individuals from elsewhere will turn up to fill in the gaps. But their research indicates otherwise. Bassing and her team gathered some of their data for this study using a novel technique that they previously published. They howled at wolves and waited to see whether they replied in Idaho and Alberta. During that research, which showed that howling at wolves was a good way to track packs in a given region, the team also collected scat samples to examine for DNA. They combined this with other data from 10 years of surveys in Idaho from 2007 to 2016 and three years in southwestern Alberta from 2012 to 2014. The wolves in Alberta are subject to higher rates of harvest than those in Idaho. Both areas have a mixture of places where wolves are protected, such as national parks, and areas where harvest is allowed. The researchers found that when a wolf is removed from a pack, it isn’t often replaced by a newcomer. Bassing said this may have something to do with the social structure of packs. Furthermore, when packs are dissolved or move out of an area, new packs also don’t come in very quickly. “Some new packs were formed at the very end of the study, but a lot of territories just remained vacant,” she said. Bassing said the longstanding assumption that immigration would fill in the gaps was based on old data that was conducted on healthy wolf populations in northern Canada. The results of her study show that the same rule doesn’t apply in southern Alberta or Idaho. This finding is mirrored in other recent work published on wolves in and around Banff National Park. Even though wolves were protected inside Banff, hunting outside park borders likely stopped a lot of emigration from happening. “I’m excited that there seems to be consistency between the results of their study and ours, especially since the data were collected through two very different methods and over different time periods,” Bassing said about the Banff study. “I believe their results support our finding that immigration does not compensate for harvest mortality in some wolf populations.” Nonetheless, most of Bassing and her team’s work was based on packs and didn’t examine lone wolves, which are harder to track and study due to their solitary nature. It’s possible that more animals are immigrating into new areas at a solitary level. “There might be a lot of immigration dynamics that are happening at a different scale,” she said. There also may be a time lag — harvesting in Idaho was legalized at the beginning of her study period, and the immigration from outsiders may have a lag effect. But the results so far show that harvesting can be an effective way of managing wolf populations, if that’s the goal of managers. In other cases, the study shows that managers trying to maintain a population at a certain level might want to think about the hunting rules in regions nearby as well as in their own. “You can’t just assume that immigrants are going to fill in and make up for that harvest,” Bassing said.

Wolf genetics in the Caucasus Mountains.
"Caucasian wolves share common haplotypes with wolves from both Eastern Europe and the Middle East, consistent with their location between these two geographic regions. Few shared haplotypes between Europe and Asia were identified previously (3 of 47, 6%; [21]). This could have resulted from the large spatial gap between the sampled areas in Europe and Asia, and the data from the Caucasian wolves are partially filling this gap. High percentage of shared haplotypes between the Caucasus and the neighbouring regions suggests that wolf populations from these areas are (or used to be) connected by a considerable level of gene flow. The microsatellite data also suggest ongoing or recent gene flow between the Caucasian and Eastern European wolf populations. Considerable level of admixture between Caucasian and Bulgarian wolves was detected, suggesting that they are connected by gene flow through intermediary populations (which is possible because of relatively continuous wolf range in the areas between the Caucasus and the Balkans). We found no evidence for genetic distinctiveness of the Caucasian wolves that would justify their classification as a distinct subspecies C. l. cubanensis, which was proposed based on morphological distinctiveness." source: Pilot, Małgorzata et al. “Genetic variability of the grey wolf Canis lupus in the Caucasus in comparison with Europe and the Middle East: distinct or intermediary population?.” PloS one vol. 9,4 e93828. 8 Apr. 2014, So it seems that Wolves in the Caucasus Mountains share some DNA with European and Asian Wolves, but have more in common with Bulgarian Wolves due to gene flow within a contiguous range. So the Wolves are more or less the Eurasian subspecies. |
