Seed Dispersal Distances for Callitris verrucosa Across Three Seasons

The Seasonal Seed Dispersal of Callitris verrucosa dataset contains empirical observations of primary wind-borne and secondary on-ground seed dispersal distances. Data was collected during spring, summer, and autumn seasons, with seeds released from three heights and wind characteristics measured using an ultrasonic anemometer. The dataset was published via the Terrestrial Ecosystem Research Network's Data Discovery portal.

Use Cases

• Modeling wind-driven seed dispersal distances based on empirical release heights and wind speed measurements.
• Comparing primary (wind-borne) and secondary (on-ground) seed dispersal patterns across different seasons.
• Studying the effect of post-fire environments on seed movement for Callitris verrucosa.
• Analyzing the relationship between horizontal wind speed and seed relocation success within a specified speed range.

Strengths

• Data collection includes detailed wind measurements (horizontal speed, direction, vertical speed) taken every 0.1 seconds.
• Experimental design is detailed, with 360 seeds released per season across six sites and three release heights.
• The study covers three distinct seasons (spring, summer, autumn) for comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data collection was constrained to wind speeds between 8-25 km/h, limiting generalizability to other conditions.
