摘要

生境建模的目的是预测水生群落结构随生境可用性的变化。它是为管理行动提供信息并在生物多样性保护和供水之间寻求最佳折衷的主要工具。这些模型的构建需要深入了解影响当地社区的主要水文和地貌驱动因素。然而,这些驱动因素在不同的空间尺度上起作用,确定哪种调查尺度是模型精度和模型可转移性之间的最佳权衡至关重要。本研究旨在通过测试微生境(流速、水深、底物)、中生境(流水、滑水、回水、孤立池塘)和空间位置(坐标和衍生空间变量)对大型无脊椎动物群落变异的影响,评估水生大型无脊椎动物栖息地模型的中尺度。采用多元空间分析方法对意大利北部特雷比亚河辫状河段的大型无脊椎动物数据进行了分析。中生境是大型无脊椎动物群落组成的良好预测因子,微生境和空间也有显著影响。这项工作的结果强调了结果在中尺度生境之间的可转移性,这支持了在辫状河中使用中尺度模型来研究大型无脊椎动物分布。

Effect of microhabitats, mesohabitats and spatial position on macroinvertebrate communities of a braided river
Abstract Habitat modelling aims to predict changes in the structure of aquatic communities as a function of habitat availability. It is a primary tool to inform management actions and to search for the best compromise between biodiversity conservation and water supply. The construction of these models requires in-depth knowledge about the main hydrological and geomorphological drivers that affect local communities. However, these drivers act at different spatial scales and determining which investigation scale is the best trade-off between model accuracy and model transferability is crucial. The present work aims to evaluate the mesoscale for habitat modelling of aquatic macroinvertebrates, by testing the effect of microhabitat (flow velocity, water depth, substrate), mesohabitat (riffles, glides, backwaters, isolated ponds) and spatial position (coordinates and derived spatial variables) on macroinvertebrate community variability. Multivariate spatial analyses were used to analyse the macroinvertebrate data collected in a braided reach of the Trebbia River (N Italy). Mesohabitat was a good predictor of macroinvertebrate community composition, although both microhabitat and space also showed a significant effect. The outcome of this work highlights the transferability of the results across mesohabitats, which supports the use of mesoscale modelling for macroinvertebrate distribution in braided rivers.
