Macroinvertebrate Community Data from Brazilian Semiarid Rock Pools, 2013

Brazilian semiarid region data from a study investigating macroinvertebrate community structure in 16 freshwater rock pools during the wet and dry seasons of 2013. The dataset includes macroinvertebrate counts and local environmental variables such as dissolved oxygen, pH, water temperature, and electrical conductivity. It was created by Luciana Santos and shared under a CC-BY-4.0 license.

Use Cases

• Modeling the influence of dispersal mode on community composition based on active vs. passive disperser counts
• Analyzing the relationship between community structure and local environmental conditions like dissolved oxygen and pH
• Studying seasonal population dynamics in temporary aquatic habitats based on wet and dry season sampling
• Investigating the role of freshwater rock pools as biodiversity refuges in semiarid landscapes

Strengths

• Data covers 16 distinct rock pool sites sampled across two seasons, providing comparative temporal data.
• Includes specific, measured environmental variables: dissolved oxygen, pH, water temperature, and electrical conductivity.
• Findings include a quantified sevenfold increase in passive disperser abundance relative to active dispersers during the dry season.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 23.1 KB, indicating a limited scope.
