Diversifying agroecosystems enhance the sustainability of agricultural production and reduce input dependency during agroecological transitions. To achieve this objective, a study was conducted to assess the impact of intercropping and the introduction of flowering plant strips on land use efficiency and crop damage in a lettuce and broccoli associ...

Many species of the sexually-deceptive genus Ophrys are characterized by insect-like flowers. Their form has been traditionally considered to play an important role in pollinator attraction and manipulation. Yet the evolution of the floral form remains insufficiently understood. We hypothesize that pollinator-mediated selection is essential for dri...

Ophrys flowers mimic sex pheromones of attractive females of their pollinators and attract males, which attempt to copulate with the flower and thereby pollinate it. Virgin females and orchid flowers are known to use the same chemical compounds in order to attract males. The composition of the sex pheromone and its floral analogue, however, vary be...

Masdevallia coccinea y Masdevallia ignea (Orchidaceae) conocidas como "banderitas", son orquídeas ornamentales muy apreciadas por cultivadores aficionados y coleccionistas. En Colombia, la presión de colecta sobre estas especies ha sido enorme y pocas po- blaciones naturales sobreviven en los departamentos de Boyacá (Arcabuco, Páramo de Berlín, Dui...

Masdevallia coccinea and the Masdevallia ignea "banderitas" are ornamental orchids which are very prized by amateur farmers and collectors. In Colombia, the harvest pressure on these species has been enormous and few natural populations survive in the departments of Boyacá (Arcabuco of Berlin Páramo, Duitama) and Santander (between Málaga and Bucar...
