Benthic Macroinvertebrate Survey in a Hong Kong Subtropical Stream

One year of macroinvertebrate data from five sampling sites along a river in the Lai Chi Wo catchment, Hong Kong, China. The dataset, authored by Keyi Wang and last updated in March 2026, captures spatial and seasonal variations in community structure. It was used to evaluate influences of environmental factors like water depth and conductivity.

Use Cases

• Modeling the influence of water depth and conductivity on macroinvertebrate distribution based on identified environmental factors.
• Analyzing seasonal biodiversity patterns between wet and dry seasons based on described richness variations.
• Comparing community structures in different river reaches and under land-use influences like farming or seawater intrusion.
• Establishing baseline data for conservation strategy development in subtropical stream ecosystems.

Strengths

• Data covers five distinct sampling sites (A, B, C, D, Z) along a river gradient.
• Includes temporal coverage across one year, capturing seasonal (wet/dry) variation.
• Identifies specific dominant taxa (Diptera, Ephemeroptera) and key environmental drivers (water depth, conductivity).

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small (122.8 KB), indicating a limited scope or preliminary investigation.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
