Phylogenomic insights into the genus Tulipa (Liliaceae): Taxonomy, evolution, and biogeography

American Journal of Botany, EarlyView.
Abstract Premise Tulips are one of the best‐known geophytes, but their taxonomy remains convoluted and their evolutionary history poorly understood. Here, we used plastid genomes to identify some issues with current classification, understand the diversification history of the genus, and identify potential species linked to historical cultivation ...

Integrating Environmental Perceptions and Value Cognition to Understand Farmers' Livelihood Capacity: Evidence From a Rocky Desertification Area in China

Land Degradation &Development, EarlyView.
ABSTRACT Rocky desertification poses a serious threat to the sustainable development of karst regions. Large‐scale ecological restoration projects for ecologically fragile areas not only improve regional ecological quality but also affect farmers' perception of rocky desertification control (PRDC) and value cognition.
