Distal Femoral Epiphysis

The distal femoral epiphyses of 142 marten (Martes americana) and 391 fisher (Martes pennanti), all trapped from November to February in the Algonquin region of Ontario, were radiographed to determine their state of fusion and the presence or absence of scar lines. These criteria indicated that on the average fusion occurred first in female marten, then in male marten, female fisher, and finally in male fisher. Thus the time of fusion in these mustelids was a function of size and possibly also of sex. Radiography of the femur of winter-trapped marten and fisher is not a good method of aging these species because the degree of fusion does not necessarily differentiate juveniles from adults.

Secondary Function ◽  
Intrinsic Muscles

Extrinsic and intrinsic muscles of the forelimbs of 25 adult fisher and 25 adult marten were described and compared and the importance of these muscles in arboreal locomotion was discussed. The forelimb myology of these two mustelids is structurally similar. The muscles of the forelimb synsarcosis and the muscles that flex the shoulder and elbow joints are particularly well developed. The existence of a strongly developed forelimb musculature needed for cursorial locomotion in marten and fisher apparently potentiates a secondary function in arboreal locomotion.

The morphological characteristics of the appendicular skeleton of 26 adult fisher and 55 adult marten were studied to determine those characteristics that could be used to distinguish between species and sexes. Measurements and illustrations were used to supplement the descriptions of most bones. The appendicular skeletons of marten and fisher are similar in structure but it is possible to distinguish between the skeletal elements of these mustelids using morphometric data. Distinction can also be made between certain postcranial skeletal remains of males and females within each species using bone measurements.

The postcranial axial skeletons of 23 fisher (Martes pennanti) and 25 marten (Martes americana) are described to determine those characteristics that could be used to distinguish between species and sexes. Measurements and illustrations were used to supplement the description of most bones. The axial skeletons of marten and fisher are similar in structure but it is possible to distinguish interspecific differences in each postcranial skeletal element of these mustelids using morphometric data. Distinction can also be made between certain elements of males and females within each species using bone measurements. The morphological basis of function is described for the spinous processes of the vertebrae.

Winter habitat use and responses to snow cover of fisher (Martes pennanti) and marten (Martes americana) in southeastern Manitoba

Body Drag

A trailing study of fisher (Martes pennanti) and marten (Martes americana) in the boreal forest of Manitoba, conducted over two winters, showed that both species preferred coniferous ridges. They also had temporal differences in their habitat use that could be partially explained by their different responses to soft snow cover. Movements of fisher were found to be restricted by the soft, thick snow cover that was present during midwinter. Fewer tracks were observed at that time, and fisher travelled upon snowshoe hare trails and their own trails more than in either the early winter period of thin snow cover or the late winter period of crust conditions. Fisher were also found to walk through the snow cover and leave a body drag in midwinter. Marten did not appear to be hindered by soft snow cover to the degree that fisher were. Marten tracks were encountered with equal frequency throughout the winter and marten never left a body drag in the snow cover. They did travel upon hare trails and their own trails to a greater extent in midwinter, but never as much as did fisher.

During October-December 1989-1991, biologists from the Vermont Fish and Wildlife Department and the USDA Forest Service reintroduced 115 (88 male, 27 female) American Martens (Martes americana) into the southern half of the Green Mountain National Forest. During the years of release, brief radio-contact was made with 9 of the 13 (8 male, 5 female) radiocollared animals, and several of these may have established residency. Results of winter track count surveys suggested the presence of at least four Martens in 1990. During winter 1994-1995, Trailmaster® cameras and boxed camera systems detected Martens at two, and Fishers (Martes pennanti) at 11, of 20 sites. During winter 1997-1998, Fishers were detected at 37 of 47 boxed camera sites, but no Martens were detected. During summer 1997 and 1998, no Marten photos were recorded at 285 pressure-plate camera stations in a larger area that included all Marten release sites. Although post-release monitoring may have been insufficient to definitively confirm Marten presence, results from the 1997 and 1998 camera surveys indicate that a viable population of Martens was not established in southern Vermont, perhaps due to competition with Fishers.

Frequency Occurrence

A tracking study of fishers, Martes pennanti, and American pine martens, Martes americana, conducted over two winters in southeastern Manitoba showed that both species preyed heavily on snowshoe hares, Lepus americanus, during a period of hare abundance. Fishers had an 84.3% frequency occurrence (n = 159) of hares in their scats, while martens had a frequency occurrence of 58.9% (n = 107). Martens had a higher frequency of microtincs and red squirrels, Tamiasciurus hudsonicus, in their diets than did fishers. This difference was reflected in the foraging behaviour of the two species, with martens exhibiting more subnivean and arboreal behaviour than fishers.

Skulls of 631 martens (Martes americana), 810 fishers (Martes pennanti), and 373 otters (Lutra canadensis) collected throughout Ontario were examined for frontal bone lesions possibly induced by sinus nematodes of the genus Skrjabingylus. No lesions were found in marten skulls. Lesions were present in 13.4% of otter skulls and their distribution was similar between sexes and among age-groups. Among fishers, 11.6% of skulls exhibited lesions. Frequency of lesions tended to increase with age, and adult male fishers had fewer than adult females. Lesions were characterized by discolouration, swelling, and perforation of frontal bones in descending order of frequency. Lesions were largely confined to the pars temporalis of the frontal bones with a small number also found on the pars frontalis.
