From passion to illegality: Understanding succulent consumers' decision to participate in the illegal online wildlife trade

People and Nature, EarlyView.
Abstract The illegal wildlife trade represents a significant threat to biodiversity. Limited research has examined the illegal trade in succulents, plants characterized by their ability to store water in their leaves, stems or roots. The growing popularity of succulents has contributed to the emergence of illicit consumer practices.

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).
