“…Many of the southern immigrants have limited distributions in the Yukon today. For example, the newly recorded bat species are likely southern immigrants, and Chiropterans may still be colonizing northwestern North America (Jung et al 2006a). Myodes gapperi and Peromyscus keeni are similarly southern immigrants.…”

“…Myodes gapperi and Peromyscus keeni are similarly southern immigrants. Further cryptic species may be present in the Yukon, for example, in the genus Peromyscus (Lucid and Cook 2007) and Myotis (Jung et al 2006a). Human-induced changes, particularly climate change, will undoubtedly affect mammalian diversity and distributions, particularly in Humphries et al 2002Humphries et al , 2004.…”

“…Youngman (1975) reported only the Little Brown Myotis, Myotis lucifugus, from the Yukon, where it is widespread and common south of 64°N. Since Youngman (1975), the Northern Myotis, M. septentrionalis, has been confirmed (Jung et al 2006a) and another species, either the Big Brown Bat (Eptesicus fuscus) or Silver-haired Bat (Lasionycteris noctivagans), has been recorded via acoustic sampling (B. Slough, unpublished data). Until recently, few mist-net or echolocation monitoring surveys for bats had been undertaken in the Yukon, and it is likely that the Order remains undersampled.…”

“…The Northern Myotis, M. septentrionalis, was first found in the Yukon in 2004 when three individuals were captured at the La Biche River (60°08'N, 124°04'W; Jung et al 2006a). Five additional specimens were captured in 2007 near Watson Lake (60°07'N, 128°49'W; Lausen et al 2008).…”

Slough, Brian G., and Thomas S. Jung. 2007. Diversity and distribution of the terrestrial mammals of the Yukon Territory: A review. Canadian Field-Naturalist 121(2): 119-127.The diversity and distribution of the terrestrial mammals of the Yukon has not been systematically reviewed since 1975, a time when the occurrences of many species were not well known. Since then, single species and community studies, biological collections and expert observations have increased our knowledge of the land mammals of the Yukon. Taxonomic studies have resulted in some additional species. We provide an update on the diversity and distribution of recent land mammals of the Yukon, including previously unreported range extensions, and include a revised checklist. Research in adjoining jurisdictions has contributed more hypothetical species for the Yukon. The mammalian fauna of the Yukon is in a relatively dynamic state, and human-induced changes, particularly climate warming, will undoubtedly influence mammalian diversity and distributions in the coming decades.

“…Little brown bats are the only species found in the study area (Jung et al, 2006;Slough and Jung, 2008). The physiology and ecology of little brown bats have been well-studied at the core of their range but not at the periphery (see Fenton and Barclay, 1980).…”

Animals are expected to adjust their behavioral patterns to improve fitness outcomes, such as fecundity or offspring survival. For long-lived hibernators, decisions made in each annual cycle may reflect considerations not just for concurrent survival and reproduction but also the pressure to maximize overwinter survival and future reproductive success. We examined how these elements manifest themselves in the body mass variation patterns of North American northern latitude temperate bats, whose size and roosting habits present considerable monitoring challenges. We characterized and compared the summer and fall mass variation patterns of little brown myotis (Myotis lucifugus) and northern myotis (M. septentrionalis) from a historic dataset. In summer, the estimated date of parturition was strongly associated with spring foraging conditions (low wind, low precipitation, and warm temperatures), and mass gain associated with female reproduction conferred considerable differentiation between the mass variation patterns of females and males. In fall, differences were most apparent among species, although adults exhibited a greater capacity for rapid mass gain than juveniles. These results demonstrate how reproductive constraints and interannual survival have important influences on the behavior of temperate bats. Future work should seek to quantify the fitness benefits of patterns identified in this study, such as the rate of prehibernation mass gain.
