摘要

河流和溪流是生态系统的重要组成部分,提供必要的资源并支持各种水生生物。河流根据地质、纬度、经度和气候的不同,具有不同的物理和化学特征。这些因素影响着水生分类群的组成及其对生态系统退化梯度的敏感性。评估这些水生生态系统的健康状况对于有效保护和管理至关重要。近年来,东非国家越来越有兴趣制定和调整以底栖大型无脊椎动物作为溪流和河流生物指标为基础的全国生态完整性评估框架。然而,目前的倡议并没有产生有约束力的政策和标准化的协议。学者们意识到缺乏对东非河流非生物和生物成分时空变化的基线研究,而这些研究是生物监测技术发展和整合的基础。本文综述了河流生态完整性评价中常用的生物评价技术及其在东非地区应用的优势、挑战和机遇。它以这些发现为基础,提出了一个系统的途径,从国家层面开始,但经过标准化,最终为非洲热带地区制定一个全面的政策层面的生物评估框架。

Advancements in macroinvertebrate-based river bioassessment research in the Afrotropical region: review and steps towards a regional framework

Rivers and streams are critical components of ecosystems, providing essential resources and supporting diverse aquatic life. Rivers have different physical and chemical characteristics based on geology, latitude, longitude, and climate. These factors influence the aquatic taxa composition and their sensitivities to ecosystem degradation gradients. Assessing the health of these aquatic ecosystems is vital for effective conservation and management. In recent years, there has been growing interest among East African countries to develop and adapt nationwide frameworks for the assessment of ecological integrity based on benthic macroinvertebrates as bioindicators of streams and rivers. Nevertheless, current initiatives have not resulted in binding policy and standardized protocol. Scholars realize the lack of baseline research in the spatial and temporal variation of abiotic and biotic components of East African Rivers, which are the foundation for development and integration of biomonitoring techniques. This review article explores the commonly used bioassessment techniques applied to river ecological integrity assessment, their strength, challenges, and opportunities in their application in East African contexts. It builds on these findings to propose a systematic pathway that begins at the national level but is standardized towards the development of a comprehensive policy-level bioassessment framework for the Afrotropical region.

期刊介绍: Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
