跨越生态系统边界的生态流通常是在空间尺度上研究的，这限制了我们对生态系统联系中广泛地理模式的理解。水生昆虫是陆地生态系统重要的资源补贴者。与其发展和传播有关的特征应决定其对陆地消费者的供应。在这里，我们综合地理空间，水生生物监测和生物性状的数据，以量化的相对重要性，几个环境梯度的潜在空间和时间特征的水生昆虫补贴在美国本土。我们发现，底栖大型无脊椎动物群落的特征组成不同的水文区域，可能会影响水生昆虫运输补贴成人。此外，一些性状与环境的关系是由水文学支撑的。大的身体分类群，可以分散进一步从流与水文稳定的条件。或者，水文变量条件与多化性类群，可以延长补贴的持续时间与周期性的出现事件在整个一年。我们还发现，人为的影响，降低了频率的个人与成人飞行，但可能会延长距离补贴旅行到陆地生态系统。总的来说，这些结果表明，自然和人为梯度可以通过改变底栖大型无脊椎动物群落的特征组成来影响水生昆虫补贴。我们提出的概念框架和性状与环境的关系表明，有希望了解生态系统之间的联系广泛的地理格局。
Ecological flows across ecosystem boundaries are typically studied at spatial scales that limit our understanding of broad geographical patterns in ecosystem linkages. Aquatic insects that metamorphose into terrestrial adults are important resource subsidies for terrestrial ecosystems. Traits related to their development and dispersal should determine their availability to terrestrial consumers. Here, we synthesize geospatial, aquatic biomonitoring and biological traits data to quantify the relative importance of several environmental gradients on the potential spatial and temporal characteristics of aquatic insect subsidies across the contiguous United States. We found the trait composition of benthic macroinvertebrate communities varies among hydrologic regions and could affect how aquatic insects transport subsidies as adults. Further, several trait–environment relationships were underpinned by hydrology. Large bodied taxa that could disperse further from the stream were associated with hydrologically stable conditions. Alternatively, hydrologically variable conditions were associated with multivoltine taxa that could extend the duration of subsidies with periodic emergence events throughout the year. We also found that anthropogenic impacts decrease the frequency of individuals with adult flight but potentially extend the distance subsidies travel into the terrestrial ecosystem. Collectively, these results suggest that natural and anthropogenic gradients could affect aquatic insect subsidies by changing the trait composition of benthic macroinvertebrate communities. The conceptual framework and trait–environment relationships we present shows promise for understanding broad geographical patterns in linkages between ecosystems.
