Abstract

Wild boar (Sus scrofa L.) is one of the most discussed game species, distributed across Europe, therefore the management of this species is considered important. This management should be based on data presented, population quality and preferences and craniometric dimensions show the development of the individual and its prosperity. A sample of 148 male and 153 female wild boar mandibles was studied to compare differences in craniometric measurements, especially to find out wild boar environmental demands and population trends. The width of the caput mandibulae and angle of the mandible showed significant difference between males and females. Measurements analysed with forest area size and other data also showed that larger craniometric dimensions were reached in hunting areas with at least 200 ha of forested area, which may be due to the wild boar’s need for safety and vegetative cover in the first months of piglet development with respect to its home range. The development of young wild boar is dependent on rest and shelter in the first months of life. A forest cover of at least 200 ha appears to be sufficient in this respect. Information on habitat preferences and individual development can lead to improvements in wild boar management.
下颌骨说明了野猪的什么:个体发育、两性二态性和栖息地偏好
野猪(Sus scrofa L.)是讨论最多的狩猎物种之一,分布在欧洲各地,因此对该物种的管理被认为是重要的。这种管理应基于所提供的数据、人口质量和偏好以及显示个人发展及其繁荣程度的颅骨测量尺寸。研究了148个雄性和153个雌性野猪的下颌骨样本,比较了颅骨测量的差异,特别是了解了野猪的环境需求和种群趋势。下颌骨的宽度和下颌骨的角度在男性和女性之间有显著差异。根据森林面积大小和其他数据分析的测量结果还表明,在森林面积至少为200公顷的狩猎区,达到了更大的颅骨尺寸,这可能是由于野猪在仔猪发育的头几个月需要安全和植被覆盖,相对于其家园范围。野猪幼崽在出生后的头几个月依赖于休息和庇护。在这方面,至少200公顷的森林覆盖似乎就足够了。关于栖息地偏好和个体发展的信息可以改善野猪的管理。
