Nuestra especie entró en grupos pequeños al continente americano a través de Beringia hace 20-15 000 años. Compartió con Siberia Oriental el chamanismo y con él la búsqueda de plantas y hongos alucinógenos y, como consecuencia, el conocimiento detallado de la flora y el continuo interés por experimentar. Al entrar en el interior del continente americano, nuestra especie contribuyó –por la caza continua– a la extinción de su megafauna.

Introduction The Cañete River watershed located in the central Peruvian Andes, is undergoing hydrological changes due to global rising temperatures, landuse changes and increased water supply demand.

White mold, caused by the fungus Sclerotinia (Whetzelinia) sclerotiorum, is distributed worldwide and has more than 300 hosts. It infects flowers, cotyledons, seeds, leaves or injured plant tissue. The disease can be controlled by crop rotation, flooding, reduced seeding rates, application of chemical products in the middle of the flowering period, modifying plant architecture and the use of resistant var. Many soil microorganisms are associated with sclerotia and may cause them to degrade or fan to germinate. The symptoms and damage caused by the disease are illustrated in color.
