Morphological variation was studied in 124 accessions from 61 Passiflora L. species. Twenty-four quantitative descriptors selected for their high variation among subgenera were submitted to a principal component analysis. The first principal component (32% of total variance) was associated with f...

Por su agradable sabor y contenido nutricional, la granadilla (Passiflora ligularis Juss.) es una de la principales especies frutales de la región Andina tropical. A pesar de su importancia, existe poca información relacionada con los sistemas de polinización que permitan determinar la compatibil...

Understanding how climate change can affect crop-pollinator systems helps predict potential geographical mismatches between a crop and its pollinators, and therefore identify areas vulnerable to loss of pollination services. We examined the distribution of orchard species (apples, pears, plums an...
