Macroinvertebrate Functional Traits in a Nigerian Stream, 2022

45 trait attributes for macroinvertebrates were analyzed over twelve months across four stations in Emu Stream, North-Central Nigeria. Yakubu Manbe Mohammed collected samples using standard methods to assess responses to environmental gradients. The study demonstrates trait responses to anthropogenic disturbances and seasonal variability in a tropical freshwater ecosystem.

Use Cases

• Analyzing trait-environment associations based on RLQ and fourth-corner analysis mentioned in the description
• Studying spatial and seasonal variability in macroinvertebrate communities based on the 12-month sampling period
• Modeling responses of functional traits like body size and feeding habits to gradients of flow and pollution
• Investigating the impact of nutrient enrichment and organic pollution on freshwater biodiversity

Strengths

• Analysis of 11 biological traits comprising 45 trait attributes
• Data collected over a twelve-month period (January to December 2022)
• Multivariate approaches including RLQ ordination were employed, with the first two axes accounting for 79.98% of total inertia

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
