Invasive Beetle and Grass Interactions on South Georgia

15.1 KB of field and laboratory measurements from South Georgia (54°26’S, 36°33’W) used to study the effects of invasive grass Poa annua on invasive beetle Trechisibus antarcticus. Víctor M. Escobedo authored the dataset, which was last updated on 2026-05-05. The data includes beetle abundance, morphology, physiological stress responses, and microhabitat thermal measurements across three microsite types.

Use Cases

• Model invasive species interactions based on beetle abundance and grass turf data.
• Analyze physiological stress in beetles based on Hsp70 concentration measurements.
• Study microhabitat thermal buffering based on substrate temperature and thermal decoupling records.
• Compare morphological traits of beetles across different microsite types based on body mass and length measurements.

Strengths

• Data is structured into a metadata sheet providing variable definitions and units.
• Field sampling followed a standardized protocol with repeated visual censuses and in-situ measurements.
• Laboratory procedures for Hsp70 determination are documented in supplementary material.

Limitations

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