摘要

畜牧业是保护半天然草原生物多样性的一种常见管理做法。然而，具体管理制度对物种多样性的影响在不同的分类群中可能有很大差异。我们研究了绵羊放牧对蚂蚁物种多样性的短期影响。我们调查了一个季节的绵羊放牧是否会影响蚂蚁的物种丰富度，并导致物种发生的组成变化。我们在波兰南部的五个Natura 2000地点进行了研究，这些地点为嗜热和喜干蚂蚁创造了有利的栖息地。与未分级的地块相比，在放牧地块中检测到的蚂蚁平均数量略高，但并不显著。仅在未分级的地块中检测到三个物种。我们的结果与其他报告一致，得出的结论是，蚂蚁多样性的变化可能主要是由特定地点的条件驱动的，而不是放牧本身。

Xerothermic Grassland Protection by Means of Sheep Grazing: What is the Short-Term Effect on Ants?

Livestock grazing is a common management practice recommended to protect biodiversity of semi-natural grasslands. However, the effects of specific management regimes on species diversity can differ considerably among taxonomic groups. We studied short-term effects of sheep grazing on species diversity of ants. We investigated whether one season of sheep grazing affects the species richness of ants and causes a compositional change in species occurrence. We conducted our study in southern Poland at five Natura 2000 sites that create favourable habitats for thermo- and xerophilic ants. The average number of ant species detected in grazed plots was slightly but insignificantly higher as compared with that in ungrazed ones. Three species were detected only in ungrazed plots. Our results are in accordance with other reports, leading to the conclusion that the variation in ant diversity may be primarily driven by site-specific conditions rather than grazing per se.

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.
