简介
- Long‐term ecological data were used to evaluate diversity components of aquatic communities at different spatial scales in the Upper Paraná River floodplain.
- Diversity of aquatic macrophytes, fish and zooplankton communities were expected to vary in response to temporal variability in hydrological regime and associated environmental heterogeneity.
- Results support the importance of β‐diversity (diversity among sites within a floodplain) for γ‐diversity (regional diversity) at both small (e.g. lakes within a subsystem) and large spatial scales, such as subsystems comprised of a main river channel and associated lakes. Interestingly, diversity components for all groups exhibited low temporal variability, despite relatively high temporal variation in γ‐diversity.
- Temporal variability of diversity components and environmental variables were not correlated, indicating that the underlying ecological mechanisms driving …
