[32], A snowy habitat in many parts of the range of the American marten provides thermal protection[26] and opportunities for foraging and resting. [30] Annual reproductive output is low according to predictions based on body size. [15] Observations from Oregon[22] and Yukon[15] suggest that juveniles may disperse in early spring. living in the Nearctic biogeographic province, the northern part of the New World. The Encyclopedia of Mammals. The American marten (Martes americana) is a carnivorous, furbearing member of the weasel family. Potvin, Francois; Breton, Laurier. [8] Females give birth in late March or April to a litter ranging from 1 to 5 kits. However, as mammals, we know that the female nurses her offspring and provides them with protection and a home for the first part of their lives.

[20] Home range overlap is generally minimal or nonexistent between adult males[15][18][25] but may occur between males and females,[15][18] adult males and juveniles,[18][26] and between females. Sacramento, CA: California State University. Age and recruitment ratios suggested that there were few reproductive American marten where snow was shallow and few reproductive fishers where snow was deep. Predators have not been reported for American martens. The role of visual cues in communication has not been reported, but in many Mustelids, body postures play an important role in communication. Martes americana does not hibernate and is active all winter. [6], Home range size of the American marten is extremely variable, with differences attributable to sex,[16][17][18][19] year, geographic area,[6] prey availability,[6][20] cover type, quality or availability,[6][20] habitat fragmentation,[21] reproductive status, resident status, predation,[22] and population density. [6] Population density may vary annually[14] or seasonally. [37] High American marten mortality in Newfoundland was caused by encephalitis. The name "pine marten" is derived from the common name of the distinct Eurasian species Martes martes. up to 17 years. Lifespan/Longevity. Macdonald, Dr. David. This small animal has golden brown fur with a yellow chest. [41], The fur of the American marten is shiny and luxuriant, resembling that of the closely related sable. The full recovery of the population by 1990 is a DNR management success story. They den in hollow trees, crevices, or vacant ground burrows. [18] In an area burned 8 years previously in interior Alaska, home range boundaries coincided with transition areas between riparian and nonriparian habitats. having the capacity to move from one place to another. the area in which the animal is naturally found, the region in which it is endemic. Powell, Roger A.; Buskirk, Steven W.; Zielinski, William J. Pocatello, ID: Idaho State University. Record longevity in captivity is 17.8 years . Eyes open by the age of 39 days. [43] Trapping may impact population density, sex ratios and age structure. Pg 84. Snowfall pattern may affect distribution, with the presence of American marten linked to deep snow areas. [19] Of 18 American marten killed by predators in northeastern Oregon, 8 were killed by bobcats (Lynx rufus), 4 by raptors, 4 by other American marten, and 2 by coyotes. It is smaller and has a lighter color than the fisher (Martes Pennanti). [7] They are polygamous, and females may have multiple periods of heat. 1990. The head is gray, legs and tail are very dark brown or black, the chest has a cream colored patch, and the back is light brown. Martes americana americana subspecies group: Martes americana caurina subspecies group: The American marten is broadly distributed in northern North America. Marten pelts are very valuable and are taken in controlled hunts. Shults, Bradley Scott. Thesis, Hauptman, Tedd N. (1979). Grzimek's Encyclopedia of Mammals, Vol. Life history traits (averages) They have a pointed snout and large round ears in comparison to their head. Diet is generally more diverse in the eastern and southern parts of American marten's distribution compared to the western part,[30] though there is high diversity in the Pacific states. McGraw-Hill Publishing Company. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). In spite of these threats, American martens are not considered endangered. Synapomorphy of the Bilateria. Overlap zones were areas with intermediate snow levels. Most females spend more than 50% of their time attending dens in both pre-weaning and weaning periods, with less time spent at dens as kits aged. In an unharvested population in northeastern Oregon, the probability of survival of American marten ≥9 months old was 0.55 for 1 year, 0.37 for 2 years, 0.22 for 3 years, and 0.15 for 4 years. They also swim and dive well. Buskirk, Steven W.; Ruggiero, Leonard F. (1994). Their close relatives the pine or American marten produce odors that are only weakly perceptible to humans, despite their close relation to odiferous mammals including skunks [2].
