Abstract

Floodplain forests are among the most endangered ecosystems worldwide, even though they are hotspots for numerous taxa. The abandonment of traditional management and large‐scale timber extraction, such as clear‐cutting, has led to a decline in floodplain forest biodiversity. Retention forestry has the potential to facilitate the implementation of an ecologically sustainable forest management approach. Despite the increasing popularity of this method, its potential for spider diversity conservation, especially its comparison with the widespread practice of clear‐cutting, is still poorly studied. We studied the short‐term effect of forestry treatments (dispersed retention with 60% retained trees and clear‐cutting) on the diversity of ground‐dwelling spiders in the floodplain forests along the Lower Morava (March) and Dyje (Thaya) rivers in the Czech Republic. Spiders were sampled using pitfall traps during 2021 (pre‐harvest year) and 2022 (post‐harvest year). A total of 10,005 specimens from 167 species were recorded. Both forestry treatments simplified habitat structure compared with pre‐harvest conditions, resulting in lower beta‐diversity within sites. However, dispersed retention had higher alpha‐ and beta‐diversity than clear‐cuts, indicating that retention provided a more complex‐structured habitat. Dispersed retention and clear‐cuts hosted distinct spider assemblages with characteristic indicator species. Species typical of open and significantly disturbed habitats preferred clear‐cuts, while species typical of forests and (semi‐) open habitats, including threatened species, showed a preference for dispersed retention. Our results demonstrated, for the first time, that dispersed retention forestry could serve as an effective management tool for conserving the ground‐dwelling assemblages of spiders in floodplain forests.
生态上可持续的保留林支持下摩拉瓦联合国教科文组织生物圈保护区的蜘蛛生物多样性
洪泛平原森林是全球最濒危的生态系统之一,尽管它们是众多生物分类群的热点。放弃传统管理和大规模木材采伐(如砍伐)导致洪泛平原森林生物多样性减少。保留林有可能促进生态可持续森林管理方法的实施。尽管这种方法越来越受欢迎,但其在保护蜘蛛多样性方面的潜力,尤其是与普遍采用的皆伐做法的比较,仍然鲜有研究。我们研究了林业处理方法(保留 60% 树木的分散保留法和砍伐法)对捷克共和国莫拉瓦河下游(马奇河)和迪耶河下游(塔亚河)洪泛平原森林中地栖蜘蛛多样性的短期影响。在 2021 年(采伐前)和 2022 年(采伐后)期间,使用坑式陷阱对蜘蛛进行了采样。共记录了 167 个物种的 10 005 个标本。与采伐前相比,两种林业处理方法都简化了栖息地结构,导致地点内的β多样性降低。不过,分散保留地的阿尔法和贝塔多样性均高于砍伐地,这表明保留地提供了结构更复杂的生境。分散保留地和开阔地拥有不同的蜘蛛群落和特征指示物种。典型的开阔和受严重干扰的栖息地物种更喜欢开阔地,而典型的森林和(半)开阔栖息地物种(包括受威胁物种)则更喜欢分散保留地。我们的研究结果首次证明,分散保留林可以作为一种有效的管理工具,保护洪泛平原森林中的地栖蜘蛛群。
