At a time when historical biogeography appears to be again expanding its scope after a
period of focusing primarily on discerning area relationships using cladograms, new inference …

Historical biogeography is increasingly studied from an explicitly statistical perspective, using
stochastic models to describe the evolution of species range as a continuous-time Markov …

Programs for Bayesian inference of phylogeny currently implement a unique and fixed suite
of models. Consequently, users of these software packages are simultaneously forced to …

Cladistic biogeographic methods remain susceptible to the confounding effects of “pseudo-congruence”
and “pseudo-incongruence” because they were not designed to incorporate …

Bayesian analysis of macroevolutionary mixtures (BAMM) has recently taken the study of
lineage diversification by storm. BAMM estimates the diversification-rate parameters (…

Control of pain and stress for children is a vital component of emergency medical care.
Timely administration of analgesia affects the entire emergency medical experience and can …

We explore patterns of diversification in the plant clades Adoxaceae and Valerianaceae (within
Dipsacales), evaluating correlations between biogeographic change (ie, movements into …

Emergency physicians have used point-of-care ultrasonography since the 1990s. Pediatric
emergency medicine physicians have more recently adopted this technology. Point-of-care …

Maternally transmitted Wolbachia, Spiroplasma, and Cardinium bacteria are common in
insects [1], but their interspecific spread is poorly understood. Endosymbionts can spread …

Many fundamental questions in evolutionary biology entail estimating rates of lineage
diversification (speciation–extinction) that are modeled using birth–death branching processes. …
