Agrestes

Agrestes is a genus of voles in the family Cricetidae. These small rodents are found primarily in Eurasia. They are distinguished by their preference for grassland and field habitats, often characterized by dense vegetation. The genus name Agrestes is derived from the Latin word "agrestis," meaning "rustic" or "belonging to the field," reflecting their typical environment.

Species within the Agrestes genus have historically been subject to taxonomic debate and reclassification. A prominent member of this genus, often referenced in ecological studies, is the field vole (Microtus agrestis). However, whether Microtus agrestis should be classified within Agrestes or retained in Microtus is a matter of ongoing discussion among zoologists. This debate arises from phylogenetic analyses and morphological comparisons.

The biology of voles in Agrestes generally includes rapid reproduction rates, leading to fluctuating population densities. Their diet consists mainly of grasses, herbs, and other vegetation. These voles are important prey animals for various predators, playing a significant role in grassland ecosystems. Their burrowing behavior can also influence soil structure and plant distribution. The exact definition and content of the Agrestes genus remains somewhat fluid depending on the phylogenetic approach employed.
