Taiwan, located at the northernmost extent of Huxley’s Line, marks the furthest point along this biogeographic boundary where exchanges of flora and fauna occur. The genus Piper , a globally distributed and taxonomically complex group of both economic and evolutionary importance, has a convoluted taxonomic history in this transitional zone that requires comprehensive study. Here, we integrate morphological, molecular, and dist...

Aims Cover crops enhance agroecosystem multifunctionality by modulating biodiversity, yet knowledge of their functional diversity remains limited. This study aimed to systematically evaluate the effects of cover crop species richness (SR) and functional group richness (FGR) on ecosystem multifunctionality (EMF) in citrus orchards. Methods This study assessed 33 cover crop planting schemes in citrus orchards in Southwest China,...
