摘要

两性栖息地隔离影响动物分布，并可能导致不同性别的生活史。利用瑞士阿尔卑斯地区非侵入性遗传种群监测数据，从宏观(栖息地范围)和微观(颗粒位置)两方面研究了山兔(Lepus timidus)在繁殖早期和生殖后期的性别相关栖息地分离。数据集包括6年(2014-2019年)的抽样，包括119个人(70名男性，49名女性)。在宏观尺度上，两个时期的性别相关生境隔离程度都较弱，但在繁殖前期的性别相关生境隔离程度高于生殖后期。雌性的母地在繁殖早期含有较高比例的林分。在微观尺度上，两期生境特征的性别相关生境隔离度均较低。结果表明，在繁殖前期和繁殖后期，雌雄山地兔的生境隔离较弱。

Weak Habitat Segregation between Male and Female Mountain Hares (Lepus timidus)

Sexual habitat segregation affects animal distribution and can lead to different life-histories across sexes. We investigated sex-related habitat segregation in the mountain hare (Lepus timidus) during the early-breeding and post-reproductive periods at the macro- (home range) and microscale (pellet location) by using pellet data sets from a non-invasive genetic population monitoring in the Swiss Alps. The data sets comprise six years (2014–2019) of sampling and include 119 individuals (70 males, 49 females). At the macroscale, the sex-related habitat segregation was weak in both periods but higher in the early-breeding period as compared with that in the post-reproductive period. Home ranges of females contained a higher proportion of forest stands in the early-breeding period. At the microscale, the sex-related habitat segregation for habitat characteristics was low in both periods. We conclude that habitat segregation between male and female mountain hares is weak during the early-breeding and post-reproductive periods.

期刊介绍： Annales Zoologici Fennici publishes mainly original research reports, but also in-depth reviews and commentaries on all aspects of animal ecology and evolution, and fields related to them. Our aim is to promote papers which focus on the interactions among various components in the past and present environments by using integrative and cross-disciplinary approaches. This may be achieved by employing tools from different fields of research, such as (but not restricted to): ecology and paleoecology, molecular ecology and phylogeography, conservation biology, human-induced contemporary evolution and wildlife management, animal behaviour and interactions (including recognition systems and mechanisms), paleontology (except systematics and taxonomy) and evolution, bioenergetics.
