Scientists from IEE RAS have identified the predominant vole species in the Moscow section of Losiny Ostrov National Park, which is under the jurisdiction of the Moscow Department of Culture.
At the request of the Moscow Department of Nature Management, the institute's specialists conducted a study that revealed that rodents of the genus gray voles inhabit the park's meadow areas. Until the last century, these animals were classified as common voles - they were often found in meadows and vegetable gardens - but later, geneticists discovered that this name refers to two closely related species: the common vole and the Caspian gray vole.
They are indistinguishable in appearance: they are small rodents with dark to grayish-brown upperparts, a whitish belly, and a two-colored tail. Mice feed on vegetative parts of plants and produce an average of six pups per litter, but it is worth noting that the Caspian gray vole is better adapted to urban conditions.
Using modern molecular genetic methods, specialists analyzed the samples and obtained the following result: all the animals studied are Caspian gray voles. This species plays a vital role in maintaining the ecosystem balance of the Moscow section of Losiny Ostrov National Park, serving as food for birds of prey, foxes, and small mustelids, and also impacting the soil and vegetation.
The Moscow Department of Nature Management reminds everyone to exercise caution when walking in green areas. Walk only on designated paths, avoiding damage to plants. Leaving litter is strictly prohibited. It is also important to remain quiet and keep pets on a leash to avoid disturbing local wildlife.
