American marten canadensis"), mountain lion ("Puma concolor"), fisher ("M. pennanti"), wolverine ("Gulo gulo"), grizzly bear ("Ursus arctos horribilis"), American black bear ("U. americanus"), and grey wolf ("C. lupus"). In northeastern Oregon, most predation (67%) occurred between May and August, and no predation occurred between December and February. The fur of the American marten is shiny and luxuriant, resembling that of the closely related sable. At the turn of the twentieth century, the American marten population was depleted due to the fur trade. The Hudson's Bay Company traded in pelts from this species among others. Numerous protection measures and reintroduction efforts have allowed
5026 Martes well-defined rotation period of 4.4243 hours with a brightness amplitude of 0.69 magnitude (). According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Martes" measures 8.967 kilometers in diameter and its surface has an albedo of 0.066, which is typical for carbonaceous asteroids. The "Collaborative Asteroid Lightcurve Link", however, assumes a standard albedo for stony asteroids of 0.20 and consequently calculates a much smaller diameter of 4.93 kilometers, due to the higher albedo. This minor planet was named for the two species of the family Mustelidae, the pine marten and beech marten.
