Acoustic Occupancy Data for Pristimantis turpinorum in Tobago, 2024

Passive acoustic monitoring data from 24 sites on the Caribbean island of Tobago collected over four months in 2024. The dataset was created by Renoir Auguste to model site occupancy of the Data Deficient frog Pristimantis turpinorum and assess the presence of a non-native competitor. It includes detection data used to estimate an extent of occurrence of 7.81 km² for P. turpinorum.

Use Cases

• Modeling amphibian site occupancy based on acoustic detection probability and environmental covariates like elevation and stream proximity.
• Mapping the potential distribution of a Data Deficient species based on estimated extent of occurrence.
• Assessing the presence or absence of a non-native species (Eleutherodactylus johnstonei) as a potential conservation threat.
• Informing conservation strategies for a specific amphibian species and its habitat within a globally important conservation area.

Strengths

• Data collection is explicitly described, involving 24 monitoring sites over a four-month period in 2024.
• Analysis produced a specific, quantitative estimate for the species' extent of occurrence (7.81 km²).
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• The dataset is very small (44.7 KB), indicating limited scope and likely summary-level data rather than raw audio files.
• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
