Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban...

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

Hesperozygis ringens (Lamiaceae) is an aromatic plant, native to the South of Brazil, popularly called “espanta pulga”. Although there are some proven pharmacological activities for the species, their knowledge is very modest. Thus, the objective of this work was to evaluate the antitrypanosomal, nematicidal, and antibacterial activities of extract...
