“…Hence, seasonally lowered extrinsic mortality may select for a delayed onset of maturity and reduced reproductive rate. The common dormouse, therefore, may provide unique insights into the evolution of life history tactics in general, yet surprisingly little is known about the seasonal or annual survival rates in this or--for that matter--other small hibernators (but see Meaney et al 2003;Schorr et al 2009). …”

High survival during hibernation affects onset and timing of reproduction

The timing of reproduction is one of the most crucial life history traits, with enormous consequences for the fitness of an individual. We investigated the effects of season and timing of birth on local survival probability in a small mammalian hibernator, the common dormouse (Muscardinus avellanarius). Local monthly survival probability was lowest in the early active season (May-August, ϕ(adult) = 0.75-0.88, ϕ(juvenile) = 0.61-0.68), increased during the late active season (August-October), and highest during hibernation (October-May, ϕ(adult) = 0.96-0.98, ϕ(juvenile) = 0.81-0.94). Consequently, dormice had an extremely high winter survival probability. We observed two peaks in the timing of reproduction (June and August/September, respectively), with the majority of juveniles born late in the active season. Although early investment in reproduction seems the better life history tactic [survival probability until onset of reproduction: ϕ(born early) = 0.46, 95% confidence interval (CI) 0.28-0.64; ϕ(born late) = 0.19, 95% CI = 0.09-0.28], only females with a good body condition (significantly higher body mass) invest in reproduction early in the year. We suggest the high over-winter survival in dormice allows for a unique life history pattern (i.e., combining slow and fast life history tactics), which leads to a bimodal seasonal birth pattern: (1) give birth as early as possible to allow even the young to breed before hibernating, and/or (2) give birth as late as possible (leaving just enough time for these young to fatten) and enter directly into a period associated with the highest survival rates (hibernation) until maturity.

“…In Z. h. preblei there are two peaks in reproduction with young of early litters first captured in July, and young of late litters first captured after 1 August; some females might be able to produce two litters (Meaney et al 2003). Population numbers of Z. h. preblei expand in August as a result of young of the year animals entering the population (Meaney et al 2003). However, field studies on Z. h. luteus conducted during the last two decades found no detectable expansion of the population in August, though there is a small pulse of presumably late litter young at the end of the active season ( Table 3).…”

“…However, immergence of adults into hibernation could occur earlier. In Z. h. preblei some adults were imminently ready for hibernation in the third week in August (Meaney et al 2003). The active interval for montane populations cannot be as precisely determined, but is ca 124 -135 days (ca 4 to 4.5 months) for Fenton Lake (13 June to probably mid-October ).…”

“…This long period of hibernation is a key natural history attribute that influences many other important aspects of the species' biology (Kirkland andKirkland 1979, Tur bill et al 2011). Hibernation is advantageous because survival rates tend to be higher during hibernation than during the active season, presumably due to reduced exposure to predators (Meaney et al 2003, Turbill et al 2011, but see Schorr et al 2009). However, recovery from hibernation, reproduction, and gain in fat to enter and survive the next hibernation all must happen within a brief active period during the warmer months.…”

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.
