Maned wolf photos and images – black and white wolf backgrounds


Gestation lasts 60 to 65 days and a litter may have from two to six pups. One litter of seven has been recorded. Birthing has been observed in May in the Canastra Mountains, but data from captive animals suggest that births are concentrated between June and September. The maned wolf reproduces with difficulty in the wild, with a high rate of infant mortality. Females can go up to two years without breeding. Breeding in captivity is even more difficult, especially in temperate parts of the Northern Hemisphere.

Pups are born weighing between 340 and 430 grams. They begin their lives with black fur, becoming red after ten weeks. The eyes open at about 9 days of age. They are breastfed up to 4 months. Afterwards, they are fed by their parents via regurgitation, starting on the 3rd week of age and lasting up to 10 months. Three-month-old pups begin to accompany their mother while she forages. Males and females both engage in parental care, but it is primarily done by the females. Data on male parental care has been collected from captive animals and little is known whether this occurs frequently the wild. Maned wolves reach sexual maturity at 1 year of age, when they leave their birth territory.

The maned wolf’s longevity in the wild is unknown, but estimates in captivity are between 12 and 15 years. There is a report of an individual at the São Paulo Zoo who lived to be 22 years old.

Japanese wolf
The Japanese wolf inhabited Kyushu, Shikoku, and Honshu Islands but not Hokkaido Island. This indicates that its ancestor may have migrated from the Asian continent through the Korean Peninsula into Japan. The phylogenetic tree generated from its mitochondrial DNA sequences revealed a long branch that separated the Japanese wolf from other gray wolf populations and that it belongs to the ancient mDNA haplogroup 2 (represented today by the Italian wolf and scattered pockets of other wolves across Eurasia), while the Hokkaido wolf belongs to mDNA haplogroup 1 and this suggests that the Japanese wolf was the first arrival on the Japanese archipelago with the Hokkaido wolf arriving more recently from the north. The wolf was estimated to have arrived in Japan during the Late Pleistocene between 25,000–125,000 years ago, however a more recent study that looked at the past sea levels of the Korean Strait together with the timing of the Japanese wolf sequences indicated that it arrived to the southern islands less than 20,000 YBP.

In 2016, a whole-genome DNA study proposed, based on the assumptions made, that all of the North American wolves and coyotes diverged from a common ancestor less than 6,000–117,000 years ago, including the coyote diverging from Eurasian wolf about 51,000 years ago (which matches other studies indicating that the extant wolf came into being around this time), the red wolf diverging from the coyote between 55,000–117,000 years ago, and the eastern wolf (Great Lakes region and Algonquin) wolf diverging from the coyote 27,000-32,000 years ago, and asserts that these do not qualify as an ancient divergences that justify them being considered unique species. The study also indicated that all North America wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly admixed with different proportions of gray wolf and coyote ancestry. The study found that coyote ancestry was highest in red wolves from th...

In Italy, the earliest remains of a wolf (Canis lupus) have been found in 1984 at the Middle Pleistocene site of La Polledrara di Cecanibbio, 20 km north-west of Rome in deposits dated 340-320 thousand years ago. The genetic analysis of Apennine wolves indicates that they went through a population decline of 100–1,000 fold between the past 4,700–23,800 years, which indicates genetic isolation south of the alps from other wolf populations for many thousands of years. In 1992, an examination of the mitochondrial DNA (mDNA) of 26 grey wolf populations worldwide revealed that the Italian wolf has a unique mitochondrial haplotype (a mutation) not shared by any other grey wolf population. Further tests on grey wolf mDNA revealed that, unlike several European grey wolf populations, Italian wolves do not share haplotypes with either other grey wolves or domestic dogs. In 2010, a study compared the mDNA haplotypes of 24 ancient wolf specimens from Western Europe dated between 44,000 and 1,2...

Wolf populations in Poland have increased to about 800–900 individuals since being classified as a game species in 1976. Poland plays a fundamental role in providing routes of expansion into neighbouring Central European countries. In the east, its range overlaps with populations in Lithuania, Belarus, Ukraine, and Slovakia. A population in western Poland expanded into eastern Germany and in 2000 the first pups were born on German territory. In 2012, an estimated 14 wolf packs were living in Germany (mostly in the east) and a pack with pups has been sighted within 24 kilometres (15 mi) of Berlin. The grey wolf is protected in Slovakia, though an exception is made for wolves killing livestock. A few Slovakian wolves disperse into the Czech Republic, where they are afforded full protection. Wolves in Slovakia, Ukraine and Croatia may disperse into Hungary, where the lack of cover hinders the buildup of an autonomous population. Although wolves have special status in Hungary, they may ...
