The effects of a microplastic mixture on wood frogs (Rana sylvatica) across multiple life stages in an outdoor mesocosm experiment.

ABSTRACT: Microplastics have been found across the globe in the habitats of many amphibians. To investigate how exposure to microplastics affects hatching success, survival, growth, and development of wood frogs (Rana sylvatica), as well as how these animals may act as vectors for microplastics, a 96-day outdoor mesocosm experiment was conducted at the Queen's University Biological Station (Ontario, Canada). Wood frogs were allocated to a negative control group or exposed to an additive-containing microplastic mixture (equal parts polypropylene, polystyrene, and polyethylene terephthalate) at nominal water concentrations of 0.069 g/L or 0.691 g/L. Whereas hatchling survival, hatching success, and hatchling size did not differ among experimental groups, exposure to microplastics caused increased larv
