Consumptive and Non-Consumptive Predator Effects on Ambystoma Salamander Larvae, 2022-2025

Between 2022 and 2025, 105 surveys were conducted in 36 waterbodies on Pelee Island, Ontario, Canada, to test for effects of invasive White River crayfish and native fish on small-mouthed salamander larvae. The dataset, created by Beck Bugeya and last updated in May 2026, includes catch-per-unit-effort and larval body size measurements, and a habitat suitability map for the invasive crayfish. It controls for factors like conspecific density, water temperature, and habitat conditions.

Use Cases

• Modeling habitat suitability for invasive crayfish based on the developed map.
• Analyzing the relationship between native fish presence and larval salamander catch rates.
• Investigating the effects of water temperature and conspecific density on larval body size.
• Comparing temporal trends in invasive species detection and native species presence over a four-year period.

Strengths

• Data spans four years (2022-2025) from 105 surveys across 36 distinct waterbodies.
• Includes a habitat suitability map for the invasive crayfish, providing spatial context.
• Controls for multiple confounding variables including native predators, density, temperature, and habitat.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single island population.
