In PNAS, Popp et al. (1) present a convincing molecular phylogenetic analysis of a small group of ericaceous flowering plants, Empetrum (the crowberries), which includes species distributed at high northern latitudes and high southern latitudes but nowhere in between—a so-called bipolar (or antitropical or, broadly speaking, amphitropical) disjunction (

Lightning Talk: Biopython (bio) Geography Module [PDF]
For Google Summer of Code 2009/NESCENT Phyloinformatics Summer of Code 2009, I built a Geography module for Biopython. The purpose of the module is to search, download, and process biogeographical data from GBIF, much as Biopython currently accesses ...

Historical biogeography of Melastomataceae [PDF]
Melastomataceae and Memecylaceae are pantropically distributed sister groups for which an ndhF gene phylogeny for 91 species in 59 genera is here linked with Eurasian and North American fossils in a molecular clock approach to biogeographical ...

A molecular phylogeny of Southeast Asian Cyrtandra (Gesneriaceae) supports an emerging paradigm for Malesian plant biogeography [PDF]
The islands of Southeast Asia comprise one of the most geologically and biogeographically complex areas in the world and are a centre of exceptional floristic diversity, harbouring 45,000 species of flowering plants.

A near-natural experiment on factors influencing larval drift in Salamandra salamandra
The larval stage of the European fire salamander (Salamandra salamandra) inhabits both lentic and lotic habitats. In the latter, they are constantly exposed to unidirectional water flow, which has been shown to cause downstream drift in a variety of taxa.

Does habitat stability structure intraspecific genetic diversity? It’s complicated... [PDF]
Regional phylogeographic studies have long been conducted in the southeastern United States for a variety of species. With some exceptions, many of these studies focus on single species or single clades of organisms, and those considering multiple ...

Chikungunya Beyond the Tropics: Where and When Do We Expect Disease Transmission in Europe?
Chikungunya virus disease (chikungunya) is a mosquito-borne infectious disease reported in at least 50 countries, mostly in the tropics. It has spread around the globe within the last two decades, with local outbreaks in Europe. The vector mosquito Aedes

COVID‐19 infection in CVID patients: What we know so far
Introduction In patients with common variable immunodeficiency (CVID), immunological response is compromised. Knowledge about COVID‐19 in CVID patients is sparse. We, here, synthesize current research addressing the level of threat COVID‐19 poses to CVID
