Rapid Diversification of a Species-Rich Genus of Neotropical Rain Forest Trees
Species richness in the tropics has been attributed to the gradual accumulation of species over a long geological period in stable equatorial climates or, conversely, to speciation in response toExpand

A DNA barcode for land plants
DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. ToExpand

Patterns of molecular evolution and diversification in a biodiversity hotspot: the California Floristic Province
The California Floristic Province harbours more endemic plant and animal taxa and more identifiable subspecies than any other area of comparable size in North America. We present evidence thatExpand

Historical biogeography of two cosmopolitan families of flowering plants: Annonaceae and Rhamnaceae.
Annonaceae are a pantropically distributed family found predominantly in rainforests, so they are megathermal taxa, whereas Rhamnaceae are a cosmopolitan family that tend to be found in xeric regionsExpand

A ballistics analysis of the Deep Impact ejecta plume: Determining Comet Tempel 1's gravity, mass, and density
Abstract In July of 2005, the Deep Impact mission collided a 366 kg impactor with the nucleus of Comet 9P/Tempel 1, at a closing speed of 10.2 km s−1. In this work, we develop a first-order,Expand

A phylogenetic analysis of Rhamnaceae using rbcL and trnL-F plastid DNA sequences.
Previous tribal classifications of Rhamnaceae have been based on fruit characters, resulting in the delimitation of large and otherwise heterogeneous groups. We evaluated the most recentExpand

Páramo is the world's fastest evolving and coolest biodiversity hotspot
Understanding the processes that cause speciation is a key aim of evolutionary biology. Lineages or biomes that exhibit recent and rapid diversification are ideal model systems for determining theseExpand

How to Open the Treasure Chest? Optimising DNA Extraction from Herbarium Specimens
Herbarium collections are potentially an enormous resource for DNA studies, but the use of herbarium specimens in molecular studies has thus far been slowed down by difficulty in obtainingExpand

The global effects of impact-induced seismic activity on fractured asteroid surface morphology
Abstract Impact-induced seismic vibrations have long been suspected of being an important surface modification process on small satellites and asteroids. In this study, we use a series of linkedExpand
