Abstract This study assessed invertebrate response to disturbances in the riparian zone of the Wewe river, using geometric series, rarefaction, Renyi diversity, and CCA models. We sampled 2,077 individuals (dry season) and 2,282 (wet season) belonging to 16 invertebrate orders. The severely disturbed habitat registered the highest individuals (n = 1,999), while the least was the moderately disturbed habitat (n = 740). Seasonal assemblages were not significantly different. Fire, farming, tree felling, and erosion explained 66.8% and 60.55% in the dry and wet seasons, respectively, of variations in invertebrate assemblages. This suggests threats to the invertebrate community and the riparian ecosystem health by anthropogenic interventions.

加纳阿散蒂地区威威河沿岸地区陆生无脊椎动物组合的时空动态

摘要 本研究使用几何级数、稀疏度、仁义多样性和 CCA 模型评估了无脊椎动物对威威河沿岸地区干扰的反应。我们对属于 16 个无脊椎动物目的 2,077 只个体（旱季）和 2,282 只（雨季）进行了采样。严重干扰的栖息地记录了最高的个体（n = 1,999），而最少的是中度干扰的栖息地（n = 740）。季节性组合没有显着差异。火灾、农业、砍伐树木和侵蚀分别解释了旱季和雨季无脊椎动物组合变化的 66.8% 和 60.55%。这表明人为干预对无脊椎动物群落和河岸生态系统健康构成威胁。
