Acute toxicity effects of pesticides on beneficial organisms - Dispelling myths for a more sustainable use of chemicals in agricultural environments

L. Mata, R. A. Knapp, R. McDougall, K. Overton, A. A. Hoffmann, P. A. Umina

This study assesses acute pesticide toxicity on 15 beneficial species, revealing that toxicity varies significantly across species and exposure times, challenging the use of limited representative species in toxicity testing.

Acute toxicity effects of pesticides on predatory snout mites (family Bdellidae)

R. A. Knapp, L. Mata, R. McDougall, Q. Yang, A. A. Hoffmann, P. A. Umina

This study assesses the acute toxicity of 22 pesticides on the predatory snout mite Odontoscirus lapidaria, revealing taxon-specific responses and highlighting the need for broader species representation in pesticide testing.

Reintroduction of resistant frogs facilitates landscape-scale recovery in the presence of a lethal fungal disease

R. A. Knapp, M. Q. Wilber, A. Q. Byrne, M. B. Joseph, T. C. Smith, A. P. Rothstein, R. L. Grasso, E. B. Rosenblum

This study shows reintroducing Bd-resistant frogs can recover populations despite the disease, with genetic evidence of evolutionary resistance.

Effectiveness of antifungal treatments during chytridiomycosis epizootics in populations of an endangered frog

R. A. Knapp, M. B. Joseph, T. C. Smith, E. E. Hegeman, V. T. Vredenburg, J. E. Erdman, D. M. Boiano, A. J. Jani, C. J. Briggs

This study evaluates antifungal treatments for chytridiomycosis in frogs, finding that while treatments reduce Bd load temporarily, they fail to ensure long-term population persistence.

Using visual encounter data to improve capture-recapture abundance estimates

M. B. Joseph, R. A. Knapp

This paper improves capture-recapture abundance estimates by incorporating visual encounter data, showing it increases precision when capture probabilities are low and surveys are few.

Disease and climate effects on individuals jointly drive post-reintroduction population dynamics of an endangered amphibian

M. B. Joseph, R. A. Knapp

The paper analyzes the impact of disease and climate on the population dynamics of reintroduced amphibians using mark-recapture data.
