Range Dynamics

Species across the planet are shifting their ranges in response to climate change and habitat loss. However, range shifts may vary, with populations moving in some areas but remaining stable in others; the conditions that encourage range stability rather than range shifts are poorly known. Bobcats (Lynx rufus (Schreber, 1777)) and Canada lynx (Lynx canadensis Kerr, 1792) are congeneric mesocarnivores with wide ranges across North America and range overlap in southern boreal and montane forests (the southern edge for lynx and the northern edge for bobcat). The ranges of both species are shifting in some parts of North America, in most cases resulting in a northward expansion for bobcats and a northward contraction for lynx. However, their range dynamics in the Pacific Northwest, which contains the northwestern range margin for bobcats and the southwestern range margin for lynx, have not been thoroughly documented. Here, we examine whether the range of each species has shifted in British Columbia (BC), Canada, provincially during 1983–2013 or in central BC during 1935–2013. Trapping records indicated that ranges have remained stable, and surveys from trappers supported these findings. Our findings are consistent with previous work showing that many wide-ranging species do not shift their range uniformly across their entire range edge. For bobcats and lynx, their range stability in BC contrasts with their range dynamics in other parts of North America.

Harvest records suggest that the abundance of bobcats ( Lynx rufus) has increased and the leading edge of their distribution has spread northward, while the trailing edge of the Canada lynx ( Lynx canadensis) range has contracted in Ontario, Canada. There has been a debate about whether these closely related felids might compete in areas of sympatry, but there is little research on sympatric populations of bobcat and lynx. Both species are found on the north shore of Lake Huron in Ontario, Canada, which provided an opportunity to investigate their spatial patterns and habitat use. We surveyed snowmobile routes for snow tracks over three winters and estimated probability of occupancy for the two felid species while accounting for detectability. Bobcat and lynx tracks were never found on the same survey route. Bobcat occupancy increased with habitat heterogeneity, whereas lynx occupancy increased with homogeneity. Our results fit with the common assumption of the generalist and specialist natures of bobcat and lynx, respectively. Our findings suggest that bobcats invaded former lynx territory after these areas became vacant. The story of the bobcat and the lynx is one of the loss of a unique, boreal specialist due to anthropogenic change, and eventual replacement by an adaptable generalist.

Examination of 129 bobcats (Lynx rufus) from New Brunswick, Nova Scotia, and Maine and 14 lynx (Lynx canadensis) from Newfoundland revealed the presence of adult Taenia macrocystis (Diesing 1850) in 86% of the bobcats and in all the lynx. Concurrent examination of snowshoe hares (Lepus americanus) showed that a high proportion of adult hares were infected with cestode larvae of the strobilocercus type. Scolices of these larvae were identical with scolices of T. macrocystis adults recovered from wild cats.Experimental infection of domestic cats with fresh larvae from hares yielded adult taeniids, within 42 days, which were identical with the adult T. macrocystis found in wild cats.Experimental infection of laboratory-reared snowshoe hares with eggs of these cestodes produced fully developed, infective strobilocercus larvae within 14 weeks, thus establishing that Lepus americanus acts as an intermediate host in the life cycle of T. macrocystis in northeastern North America.

The behavioural responses of lynx (Lynx canadensis) to declines in snowshoe hare (Lepus americanus) abundance were examined in the southwestern Yukon. Between April 1982 and June 1984, 11 lynx were radio tagged and monitored in and near the Kluane Game Sanctuary. Lynx home range size increased from 13.2 to 39.2 km2 concurrent with a decline in snowshoe hare abundance from 14.7 to 0.2 hares/ha. Below about 0.5 hares/ha, several lynx abandoned their home ranges and became nomadic, although they remained within the general study area. Lynx concentrated their foraging efforts in areas of relatively high snowshoe hare abundance and abandoned these areas after hares declined. Straight-line daily travel distance remained constant at 2.2−2.7 km/day above 1.0 hare/ha. Below 1.0 hares/ha, straight-line daily travel distances increased rapidly, reaching 5.5 km/day at 0.2 hares/ha. Three of seven radio-tagged lynx dispersed 250 km or more from the study area during the 1982 period of rapid hare decline. No similar long-distance emigrations were recorded after hare densities stabilized at less than 1.0 hares/ha. Trapping mortality was responsible for the loss of seven of nine radio-tagged lynx that travelled outside the game sanctuary. One lynx probably starved during the winter or spring of 1984. The high rate of trapping mortality outside the game sanctuary suggests that refugia in wilderness areas are important in maintaining lynx populations during periods of low recruitment.
