格鲁特·布鲁德林克 (Groot Bruinderink)，G.W.T.A. & Hazebroek, E. 1995：对森林/荒地生态系统中野猪的承载能力进行建模。 - 维尔德尔。生物。 1：81-87。荷兰野猪的主要栖息地由森林/石南地生态系统组成。在这个生态系统中，我们发现冬季肥大可用性和营养状况与来年春季野猪的繁殖之间存在独特的相关性。这种相关性用于根据冬季阈值密度来模拟承载能力，高于该阈值时，平均体重会随密度而降低。介绍了贫瘠沙质土壤上的森林和荒地对野猪承载能力的建模结果。该模型基于可用的桅杆和阔叶草，后者是冬季桅杆的主要替代品。
Groot Bruinderink, G.W.T.A. & Hazebroek, E. 1995: Modelling carrying capacity for wild boar Sus scrofa scrofa in a forest/heathland ecosystem. - Wildl. Biol. 1: 81-87. The main habitat for wild boar in the Netherlands consists of a forest/heathland ecosystem. In this ecosystem we found an exclusive correlation between mast availability and nutritional condition in winter and reproduction of wild boar in the succeeding spring. This correlation was used to model carrying capacity in terms of a threshold density in winter, above which the average body weight is density-dependently reduced. The results of modelling carrying capacity of an area of forests and heathlands on poor, sandy soils, for wild boar are presented. The model is based on available mast and broadleaved grasses, the latter being the main substitute for mast during winter.
