The presence of apex predators improves habitat quality and species viability down the food chain. This reintroduction could be a model for repairing ecosystems.
Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 – 135 lbs).

The wolves of the Iberian peninsula have morphologically distinct features from other Eurasian wolves and each are considered by their researchers to represent their own subspecies. [ 134 ] [ 135 ] The taxonomic reference Mammal Species of the World (3rd edition, 2005) does not recognize Canis lupus signatus ; however, NCBI / Genbank does list it.
Although African wolves are inefficient rodent hunters and thus not in direct competition with Ethiopian wolves, it is likely that heavy human persecution prevents the former from attaining numbers large enough to completely displace the latter. [59] Nevertheless, there is at least one record of an African wolf pack adopting a male Ethiopian wolf.
In Baden-Württemberg there were five records of wolves from the Alpine and Italian populations in the period 2015 to 2020. [22] [23] In September 2020, a wolf (GW 1832 m) from the Alps arrived in the Neckar-Odenwald-Kreis. [24] Individual wolves from the Dinarides-Balkans population have also migrated as far as the German Alpine region.
