As one of the most abundant game species in Europe, European wild boar () populations prove highly adaptable to cultivated landscapes. The ongoing process of climate change and the high agricultural yields seem to further optimize the living conditions for this species. In long-term reproduction monitoring, we collected data on the body weight of wild boar females. Over an 18-year period, the body weight of wild boar females increased continuously, then stopped and decreased. It was possible to detect differences between the body weights of animals from forest and agricultural areas. For these areas, differences in body weight development also led to a significant distinction in the onset of puberty. We conclude that, even in a highly cultivated landscape, forested areas provide habitat characteristics that may strongly influence reproduction. Second, with dominant agricultural areas in Germany, wild boar reproduction has been favored in recent decades.
作为欧洲数量最为丰富的猎物物种之一，欧洲野猪（Sus scrofa）种群被证明对农耕景观具有高度适应性。当前的气候变化进程以及高农业产量似乎进一步优化了该物种的生存条件。在长期繁殖监测中，我们收集了野猪雌性个体体重的数据。在18年的时间里，野猪雌性个体的体重持续增加，随后停止增长并下降。能够检测到来自森林和农业区域的动物体重之间的差异。对于这些区域，体重发育的差异也导致了青春期开始时间的显著差异。我们得出结论，即使在高度农耕化的景观中，森林区域提供的栖息地特征可能会对繁殖产生强烈影响。其次，由于德国农业区域占主导地位，近几十年来野猪繁殖得到了促进。
