Implication

Community science study reports declines in Taiwan's native frog populations linked to invasive species, suggesting ecological monitoring is essential.

Key Points

This research aims to analyze the long-term impacts of the invasive frog Polypedates megacephalus on native frog populations in Taiwan.
Analyzed longitudinal data from the Taiwan Amphibians Database spanning 2007–2023
Assessed population trends among native frogs in relation to P. megacephalus presence
Compared declines in habitat specialists versus generalists
Conducted a univariate analysis of declining native species
Relative habitat specialists showed more significant population declines than generalists
P. braueri and H. chinensis experienced greater declines than other native species
Where P. megacephalus was present, more native frogs were declining, although significance changed when considering environmental factors
Findings highlight the context-dependent relationship between P. megacephalus and native populations.
