A striking example of plant/pollinator trait matching is found between Andean species of Passiflora with 6-14-cm-long nectar tubes and the sword-billed hummingbird, Ensifera ensifera, with up to 11-cm-long bills. Because of the position of their anthers and stigmas, and self-incompatibility, these passionflower species depend on E. ensifera for pollination. Field observations show that the bird...

In current agent systems agent migration is only possible between homogeneous systems supporting identical agent platforms, limiting an agent’s possibilities considerably. This paper revisits the notion of generative migration. Generative migration entails migration of an agent blueprint, instead of complete code. This approach relies on homogeneity of libraries on different platforms to re-inc...

Passiflora mollissima (Kunth) L.H. Bailey is an exotic fruit native to South America, known as taxo in Ecuador. This paper characterizes its flavonoid and carotenoid composition and antioxidant capacity and evaluates the effect of the spray-drying process on its phytochemical composition and antioxidant capacity. A total of 18 flavonoid compounds, nine proanthocyanidins and nine flavan-3-ol mon...

Little is known about genetic variation and geographic patterns of diversity of Acacia koa. We analyzed diversity using laboratory studies of enzymes. Wide samples of koa possess significant variation in six enzyme genes; several genes have alleles in intermediate frequencies. The variable genes have average expected heterozygosity of 0.41; this indicates that koa has significant levels of gene...

The geographical distribution, ecological characteristics, flowering and fruiting times, and pollinating agents of Passiflora alata are considered and related to molecular genetic data gathered simultaneously. The first report on this species in Rio Grande do Sul was made in 1934, only in cultivated gardens. Approximately 20 years later, however, the species was already classified as efferata (...
