Abstract

Major disturbance events can profoundly influence biodiversity patterns, although the extent to which such shifts are predictable remains poorly understood. We used environmental DNA (eDNA) to compare forested versus recently deforested stream insect communities across disjunct regions of New Zealand, to test for parallel shifts in response to widescale disturbance. Although eDNA analyses revealed highly distinct species pools across regions, they detected concordant functional diversity shifts linked to recent deforestation, including parallel decreases in the diversity of grazing taxa. The finding that taxonomically distinct freshwater biotas have experienced broadly concordant functional shifts in the wake of deforestation indicates that disturbance can drive deterministic ecological change. By contrast, the finding that some closely related species within functional groups show discordant responses to deforestation suggests that ecological differentiation among cryptic taxa may contribute to idiosyncratic shifts. These findings highlight the potential of eDNA for resolving subtle species-level differences among anthropogenically impacted ecological assemblages.

重大干扰事件会对生物多样性模式产生深远影响,但人们对这种变化的可预测性仍然知之甚少。我们利用环境 DNA(eDNA)比较了新西兰不同地区森林覆盖的溪流昆虫群落和最近砍伐森林的溪流昆虫群落,以检验大规模干扰是否会导致平行变化。尽管 eDNA 分析显示各地区的物种库非常不同,但它们发现了与近期森林砍伐有关的一致的功能多样性变化,包括放牧类群多样性的平行下降。在森林砍伐之后,在分类学上截然不同的淡水生物群落经历了大体一致的功能转变,这一发现表明干扰可以驱动确定性的生态变化。与此相反,功能群中一些密切相关的物种对森林砍伐的反应并不一致,这表明隐蔽类群之间的生态分化可能会导致特异性变化。这些发现凸显了 eDNA 在解决受人类活动影响的生态组合中物种层面的微妙差异方面的潜力。

期刊介绍: ECOGRAPHY publishes exciting, novel, and important articles that significantly advance understanding of ecological or biodiversity patterns in space or time. Papers focusing on conservation or restoration are welcomed, provided they are anchored in ecological theory and convey a general message that goes beyond a single case study. We encourage papers that seek advancing the field through the development and testing of theory or methodology, or by proposing new tools for analysis or interpretation of ecological phenomena. Manuscripts are expected to address general principles in ecology, though they may do so using a specific model system if they adequately frame the problem relative to a generalized ecological question or problem. Purely descriptive papers are considered only if breaking new ground and/or describing patterns seldom explored. Studies focused on a single species or single location are generally discouraged unless they make a significant contribution to advancing general theory or understanding of biodiversity patterns and processes. Manuscripts merely confirming or marginally extending results of previous work are unlikely to be considered in Ecography. Papers are judged by virtue of their originality, appeal to general interest, and their contribution to new developments in studies of spatial and temporal ecological patterns. There are no biases with regard to taxon, biome, or biogeographical area.
