Diversity and microhabitat use of benthic invertebrates in an urban forest stream (Southeastern Brazil)

A study in the Tijuca Forest, Rio de Janeiro, reveals that microhabitat diversity significantly enhances local biodiversity of benthic invertebrates. The research found that litter and stone microhabitats supported higher taxonomic richness and diversity compared to sand, which exhibited the highest dominance. Chironomidae emerged as the most abundant family among 9,800 specimens collected using a Surber sampler across three microhabitat types. Statistical analyses confirmed significant differences in community structure indices (abundance, taxonomic richness, diversity, and dominance) and microhabitat composition. The findings underscore the importance of varied microhabitats in promoting biodiversity, even within urban forest streams.
