Worldwide, Hardware virus infections in grapevines are of concern due to the potential for economic loss.Although the grape industry in Mexico is relatively small and focused mainly on the local market, production dates back to the time of the Spanish colonization.This manuscript discusses the findings on grapevine viruses in Mexico.Nine viruses ha
Human societies depend on services provided by ecosystems, from local needs such as clean water and pest control to global services like the ozone layer and the ocean biological pump.Ecosystem services are linked to the states of the ecosystem, which are, in turn, governed by a web of ecological interactions.These interactions, along with the servi
