“…Third, as in the western harvest mouse ( Reithrodontomys megalotis ), it is possible that animals change behavior during mid-summer to become more scansorial within the herbaceous vegetation (i.e., “herbeal” sensu Wright & Frey, 2014 ), which might reduce capture rates in traps set on the ground ( Cummins & Slade, 2007 ). However, based on observations made during a radio-telemetry study, Z. h. luteus appeared highly scansorial while foraging throughout the active season ( Wright & Frey, 2014 ). Thus, there is no reason to presume capture rates would change based on a seasonal change in locomotion.…”

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 lower elevation valley populations. A low-elevation population located at Bosque del Apache National Wildlife Refuge (BANWR) in the Rio Grande valley was most similar to other subspecies 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 124–135 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). In montane populations pregnant females are known from July to late August and evidence suggests that they have a single litter per year. At BANWR two peaks in reproduction were expected based on similarity of active season to Z. h. preblei. However, only one peak was clearly evident, possibly due to later first reproduction and possible torpor during late summer. At BANWR pregnant females are known from June and July. Due to the short activity season and geographic variation in phenology of key life history events of Z. h. luteus, recommendations are made for the appropriate timing for surveys for this endangered species.

“…Although capable swimmers, jumping mice also seem to be particularly vulnerable to drowning in both natural and human-constructed pools of liquid, such as post holes, goldfish ponds, and fish hatchery runs. Compared with other small mammals, jumping mice may be more vulnerable to drowning in pools because of their normal modes of locomotion and escape behaviours; they may inadvertently enter pools, including artificial above-ground pools, through their saltatory locomotion or via their scansorial climbing in overhanging vegetation (Wright and Frey 2014). Further, the normal escape behaviour of a frightened jumping mouse consists of a few erratic ricochetal hops followed by an abrupt stop and remaining motionless (Whitaker 1963).…”

“…Consequently, an ability to swim might be a valuable adaptive trait for life in these environments. However, jumping mice are considered to have a generalized terrestrial quadrupedal mode of locomotion with some morphological specialization for saltatory and scansorial locomotion (Samuels and Van Valkenburgh 2008;Wright and Frey 2014). Other than somewhat small external pinnae with an antitragal flap, which can cover the external auditory meatus, and reduced size of testes and scrotum, jumping mice lack many of the specialized adaptations often found in semi-aquatic small mammals, such as interdigital webbing or fringes, dense non-wettable underfur, laterally compressed tail, valvular nares, and nictitating membranes (Krutzsch 1954).…”

A Review and the Conservation Implications of Aquatic Behaviour and Drowning in Jumping Mice (Dipodidae: Zapodinae)

Jumping mice (Dipodidae: Zapodinae) have a generalized terrestrial quadrupedal locomotion with specializations for saltatory and scansorial locomotion. I reviewed first-hand accounts of aquatic behaviour in the literature and confirmed that jumping mice are semi-aquatic, using both primitive quadrupedal paddling on the surface as well as the more derived simultaneous bipedal pelvic paddling while swimming underwater. Although proficient swimmers, jumping mice are also prone to drowning, especially in human-made pools. Management of populations of jumping mice with conservation concern should consider potential hazards faced by jumping mice in an aquatic environment.
