Toxicity of Commonly Used Plasticizers to the Freshwater Organisms Tilapia sparrmanii (Fish) and Caridina nilotica (Shrimp): Lethal and Sublethal Effects

Environmental Toxicology, EarlyView.
ABSTRACT The toxicity of microplastics in aquatic environments is usually due to plasticizers, the chemical additives that keep the plastic polymers together. Thus, the current study reports on the toxicity of three common plasticizers found in freshwater ecosystems and their impacts on two South African freshwater organisms at the organismal and ...

Carbon pathways and trophic attributes are conserved in carnivorous reef fishes across a major human disturbance gradient

Journal of Animal Ecology, EarlyView.
Our research leverages a natural, ecosystem‐scale experiment and cutting‐edge molecular isotope approaches to reveal that coral reef food web structure and energy flow can remain consistent across a gradient of human disturbance. Abstract Habitat degradation and overexploitation are key drivers of biodiversity loss globally.
