Phys · · 1306 words · By Thomas George Evans
Animal Welfare Biological Invasions Conservation Science

The article introduces the Animal Welfare Impact Classification for Invasion Science (AWICIS), a new framework designed to assess the suffering of individual sentient animals caused by biological invasions. It argues that while biodiversity and socio-economic impacts are well-studied, the specific welfare impacts on animals have been neglected.
