Journal ArticleDOI

Spatial phylogenetics of the native California flora

TL;DR: These analyses showed that examining the geographic distributions of branch lengths in a statistical framework adds a new dimension to California floristics that, in comparison with climatic data, helps to illuminate causes of endemism.
Journal ArticleDOI

Retracing the Hawaiian silversword radiation despite phylogenetic, biogeographic, and paleogeographic uncertainty

TL;DR: Applying an event‐based test of the progression rule of island biogeography, strong evidence is found that the dispersal process favors old‐to‐young directionality, but strong evidence for diversification continuing unabated into later phases of island ontogeny, particularly for Kauaʻi.
Journal ArticleDOI

The Universal Floristic Quality Assessment (FQA) Calculator: an online tool for ecological assessment and monitoring

TL;DR: The Universal FQA Calculator (http://universalFQA.org) as mentioned in this paper is a free, open-source web-based Floristic Quality Assessments (FQAs) calculator.
Journal ArticleDOI

Cladogenetic and Anagenetic Models of Chromosome Number Evolution: A Bayesian Model Averaging Approach.

TL;DR: A new class of models of chromosome number evolution (called ChromoSSE) that incorporate both anagenetic and cladogenetic change, and can estimate the location and timing of possible chromosome speciation events over the phylogeny.
