摘要

鞘翅目甲虫(鞘翅目:Carabidae)是有益的捕食者,也是农业景观中地栖节肢动物多样性的生物指标。我们在美国中西部进行了一项为期 30 年的长期农业生态系统研究,研究了鞘翅目甲虫群落组成、活动密度和多样性的变化。我们对比了在玉米-大豆-小麦轮作的两个以保护为导向的处理中通过陷阱取样测量的食蚁兽群落指标。其中一个处理采用传统方法,但减少了农用化学品的投入(减少投入),而另一个处理则没有合成投入(基于生物)。自 1994-95 年在同一地点进行研究以来,2019 年的总体食心虫活动密度至少下降了 58-76 %,以前的四个优势物种(均为捕食者)下降了 94-98 %,变得不常见甚至罕见。此外,在两种管理制度下,食蚁兽物种丰富度、活动密度和群落结构都出现了显著差异。在 2019 年的采样中,两种食粒物种(Harpalus compar (LeConte) 和 Harpalus pensylvanicus (DeGeer))数量的大幅增加缓解了 "以生物为基础 "处理中活动密度的下降。相比之下,减少投入处理中的食肉动物活动密度仍然很低。经过几十年的管理,与减少投入相比,基于生物方法的处理方法支持了更高的食蚁兽多样性和活动密度,群落结构也从捕食性物种向食粒性物种转变。这项长期研究为越来越多关于农业景观中昆虫减少的文献做出了贡献,并证明即使在以保护为导向的管理制度下,食蚁兽群落的丰度和物种更替也会发生变化。

Long-term agricultural management reduces abundance and alters community structure of ground beetles (Coleoptera: Carabidae)
Carabid beetles (Coleoptera: Carabidae) are beneficial predators and bioindicators of ground-dwelling arthropod diversity in agricultural landscapes. We studied changes in community composition, activity density, and diversity of carabids in a long-term agroecosystem study spanning 30 years in the US Midwest. We contrasted carabid community metrics measured by pitfall trap sampling in two conservation-oriented treatments in a corn-soybean-wheat rotation. One treatment uses conventional practices but with reduced agrochemical inputs (Reduced Input), while the other has no synthetic inputs (Biologically Based). Since a 1994–95 study on the same site, in 2019 overall carabid activity density had declined a minimum of 58–76 % with the four previously dominant species (all predators) declining 94–98 % and becoming uncommon to rare. In addition, carabid species richness, activity density, and community structure have diverged significantly under the two management regimes. In 2019 sampling, activity density decline in the Biologically Based treatment was mitigated by large increases in the abundance of two granivorous species (Harpalus compar (LeConte) and Harpalus pensylvanicus (DeGeer)). In contrast, carabid activity density in the Reduced Input treatment remained low. After decades of management, the Biologically Based treatment supported greater diversity and activity density of carabids compared to Reduced Input, and community structure shifted from predatory toward granivorous species. This long-term study contributes to the growing literature on insect decline in agricultural landscapes and demonstrates that changes in abundance and species turnover of the carabid communities can occur even under conservation-oriented management regimes.

期刊介绍: Agriculture, Ecosystems and Environment publishes scientific articles dealing with the interface between agroecosystems and the natural environment, specifically how agriculture influences the environment and how changes in that environment impact agroecosystems. Preference is given to papers from experimental and observational research at the field, system or landscape level, from studies that enhance our understanding of processes using data-based biophysical modelling, and papers that bridge scientific disciplines and integrate knowledge. All papers should be placed in an international or wide comparative context.
