Habitat characteristics and life history explain reproductive seasonality in lagomorphs

Lagomorphs show extensive seasonal variation in their reproduction. However, the factors causing this large variation have so far mostly been investigated intraspecifically and therefore provide only some exemplary comparisons of lagomorph reproductive seasonality. The present study applies both a categorical description (birth season categories 1–5) and a quantitative measure (birth season length in months) to summarize the degree of birth seasonality in the wild of 69 lagomorph species. Using a comparative approach, I tested the influence of 13 factors, comprising six habitat, five life history and two allometric variables on birth season length in lagomorphs. Leporids mainly show non-seasonal birthing patterns with high intraspecific variation. Their opportunistic breeding strategy with high reproductive output and their large distribution areas across wide latitude and elevation ranges might be the reasons for this finding. Ochotonids reproduce strictly seasonally, likely because they live at northern latitudes, are high-altitude specialists, and occur in limited distribution areas. The most important factors associated with variation in lagomorph birth seasonality are mid-latitude, mean annual temperature and precipitation of a species’ geographical range and life history adaptations including fewer but larger litters in seasonal habitats. Birth seasons become shorter with increasing latitude, colder temperatures, and less precipitation, corresponding to the decreasing length of optimal environmental conditions. Leporid species with shorter breeding seasons force maternal resources into few large litters to maximise reproductive output while circumstances are favourable. Since allometric variables were only weakly associated with reproductive seasonality, life history adaptations and habitat characteristics determine birth seasonality in Lagomorpha.

“…The reason could be because the overall harsh highelevation environments have a poor ability to sustain highdensity herbivore populations. This statement is supported by the fact that the high-elevation woolly hares exhibit a lowannual productivity compared with their lowland congeners (Lu 2010).…”

“…For the woolly hares, this must also cause a reduction in food availability. Such human disturbance is typical of alpine habitats along the mid-Yalong Zangbo River (Niu 1999, Winkler 2000, and thus highlights the importance of protecting alpine vegetation for long-term survival of the high-elevation mammals with a low reproductive potential (Lu 2010).…”

“…Many previously abundant hare species such as the European hare (Lepus europaeus) (Edwards et al 2000, Smith et al 2005, Cape hare (Lepus capensis) (Lu et al 1995, Lu 2000, Irish hare (Lepus timidus) (Dingerkus and Montgomery 2002) have experienced a substantial population decline mainly owing to human activities. The susceptibility of hares to human disturbance highlight the need to examine how the degree of vegetation degradation is related with population survival of the woolly hare, a species occurring in extreme environments and performing very low annual reproductive potentials (Lu 2010).…”

Habitat use, abundance and population dynamics of the woolly hare (Lepus oiostolus) were investigated in an alpine shrub-covering valley near Lhasa, Tibet. Counts of fecal pellets indicated that habitats outside the valley with heavily degraded shrub vegetation supported a small hare population, compared with habitats inside the valleys where vegetation was undisturbed, agricultural and hunting were lacking, and predators and herbivore competitors rare. Three types of shrub habitats with intermediate cover levels along with alpine meadow inside the valley were equally preferred by the hares, whereas willow-rhododendron, with the densest cover, was avoided. Transect surveys showed that the hare population density in the preferred habitats was 13 ind./km 2 in spring and 27 ind./km 2 in autumn. Out of seven years observations from 1995 to 2004, massive spring mortality of hares occurred only in 2000, leading to a marked population decline that year.
