“…We were unable to evaluate potential impacts from the radiocollars by comparing the behaviors of uncollared and radiocollared mice. However, similar protocols were used in prior studies (Dharman 2001, Ryon 2001, Schorr 2001, Bain and Shenk 2002 without adverse impacts (e.g., inhibition of movement). Further, our 18-g weight resulted in conservative weights, which were at the lower range of the 4-10% of body weight found to cause minimal adverse effects in past studies (Koehler et al 1987, Berteaux et al 1996, Mendoça 1999.…”

“…Recently, Schorr (2001) reported similar results for grass cover but not forb cover in relation to Preble's meadow jumping mouse densities. Preble's meadow jumping mouse may use areas with high grass cover for the construction of day and maternal nests and some hibernacula (Quimby 1951, Ryon 2001, Bain and Shenk 2002. Precipitation differed greatly between 2002 (2.04 cm/month precipitation; weather station located 12 km north of the study area at Castle Rock, CO, National Climatic Data Center, United States Department of Commerce) and 2003 (8.45 cm/month), and shrubs provided consistent protective cover and potentially food, whereas herbaceous growth was subject to the annual changes in precipitation.…”

“…For example, in a companion study that evaluated the direct response of Preble's meadow jumping mice to habitat restoration, we found that detection of supplemental cover and food resources was not guaranteed (Trainor 2004). Lastly, our research examined Preble's meadow jumping mouse habitat characteristics during their active period (Jun-Aug) and preliminary research has been conducted on Preble's meadow jumping mouse hibernation sites (Ryon 2001, Bain and Shenk 2002, Meaney et al 2003; however, the habitat requirements of Preble's meadow jumping mouse during key life-history stages prior to and as it emerges from hibernation need further investigation.…”

“…Armstrong et al (1997) described Preble's meadow jumping mouse habitat as well-developed riparian vegetation with an adjacent, relatively undisturbed grassland community near open water. After federal listing, several studies were initiated in Colorado to increase knowledge about Preble's meadow jumping mouse resource requirements and population dynamics (Meaney et al 2000, Ryon 2001, Bain and Shenk 2002, Clippinger 2002, Trainor 2004. Strong associations to forb, grass, tree, and shrub cover, as well as increased plant species richness, were documented with live trapping (Schorr 2001, Clippinger 2002.…”

Microhabitat Characteristics of Preble's Meadow Jumping Mouse High‐Use Areas

Riparian wetlands are complex ecosystems containing species diversity that may easily be affected by anthropogenic disturbances. Preble's meadow jumping mouse (Zapus hudsonius preblei) is a federally threatened subspecies dependent upon riparian wetlands along the Front Range of Colorado and southeastern Wyoming, USA. Although habitat improvements for Preble's meadow jumping mouse are designed at multiple spatial scales, most knowledge about its habitat requirements has been described at a landscape scale. Our objective was to improve our understanding of Preble's meadow jumping mouse microhabitat characteristics within high‐use areas (hotspots), which are essential for the development of effective management and conservation strategies. We evaluated Preble's meadow jumping mouse habitat by describing areas of high use and no use as determined from monitoring radiocollared individuals. A comparison of microhabitat characteristics from random samples of high‐use and no‐use areas indicated that mice use areas closer to the center of the creek bed and positively associated with shrub, grass, and woody debris cover. Distance to center of the creek bed, and percent of shrub and grass cover also had the greatest relative importance of habitat variables modeled when describing high‐use areas. High‐use areas contained 3 times more grass cover than forb cover, and overall had a greater proportion of wetland shrub and grass cover. However, proportion of cover type (shrub or grass) did not vary greatly between high‐use and no‐use areas. Our results suggest that management and conservation efforts should continue to focus on establishment of native wetland vegetation near streams and creeks. For example, vegetation should include shrubs such as willow (Salix spp.), narrowleaf cottonwood (Populus angustifolia), alder (Alnus incana), grasses such as fescue (Fescue spp.), sedges (Carex spp.), and rush (Juncus spp).

“…These females left the typical wetland habitats and became almost entirely inactive for ca 2 or more weeks in underground burrows located in woody habitats devoid of herbaceous vegetation. A similar burrow used by an adult female Z. h. preblei contained fetuses (Ryon 2001). Importantly, no females captured in May, and recorded as pregnant, had corroborating evidence of pregnancy.…”

Timing of hibernation and reproduction in the endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus)

Hibernation is a key life history feature that can impact many other crucial aspects of a species’ biology, such as its survival and reproduction. I examined the timing of hibernation and reproduction in the federally endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus), which occurs across a broad range of latitudes and elevations in the American Southwest. Data from museum specimens and field studies supported predictions for later emergence and shorter active intervals in montane populations relative to low-elevation populations. A low-elevation population located at Bosque del Apache National Wildlife Refuge (BANWR) in the Rio Grande valley was most similar to other populations of Z. hudsonius: the first emergence date was in mid-May and there was an active interval of 162 days. In montane populations of Z. h. luteus, the date of first emergence was delayed until mid-June and the active interval was reduced to ca 130 days, similar to some populations of the western jumping mouse (Z. princeps). Last date of immergence into hibernation occurred at about the same time in all populations (mid to late October). Evidence suggests that females may have a single litter per year in montane populations. At BANWR two peaks in reproduction were expected based on similarity of active season to Z. h. preblei, but the population exhibited little detectable above-ground activity in August, which could stem from a failure of the population to produce early litters. Recommendations are made with respect to appropriate timing of surveys for Z. h. luteus.
