Orchid historical biogeography, diversification, Antarctica and the paradox of orchid dispersal

Phylogeny, diversification patterns and historical biogeography of euglossine orchid bees (Hymenoptera: Apidae)

The orchid bees constitute a clade of prominent insect pollinators distributed throughout the Neotropical region. Males of all species collect fragrances from natural sources, including flowers, decaying vegetation and fungi, and store them in specialized leg pockets to later expose during courtship display. In addition, orchid bees provide pollination services to a diverse array of Neotropical...

Orchid phylogenomics and multiple drivers of their extraordinary diversification.

Orchids are the most diverse family of angiosperms, with over 25 000 species,more than mammals, birds and reptiles combined. Tests of hypotheses to account for such diversity have been stymied by the lack of a fully resolved broad-scale phylogeny. Here,we provide such a phylogeny, based on 75 chloroplast genes for 39 species representing all orchid subfamilies and 16 of 17 tribes, time-calibrat...

Orchid mantis

James O'Hanlon introduces the orchid mantis, a species of preying mantis that resembles flowers.

Orchid bees

protozoa, such as those that cause sleeping sickness, leishmaniasis, and even malaria, predominantly reproduce clonally, which is, of course, of considerable medical significance. In May 1991, Tibayrenc returned to my lab, now at UC Irvine, for 14 months of additional research. We have continued collaborating to the present. Are science and religion compatible? Evolution and religious beliefs n...
