Just out @ BMC Evolutionary Biology Phylogeny, divergence time and historical biogeography of Laetiporus (Basidiomycota, Polyporales) Author(s) Jie Song and Bao-Kai Cui Abstract: Background The aim of this study was to characterize the molecular relationship, origin and historical biogeography of the species in important brown rot fungal genus Laetiporus from East Asia, Europe, Pan-America, Hawaii and South Africa. We used six genetic markers to estimate a genus-level phylogeny including (1)

Just out @ PeerJ Title:  Neogene paleogeography provides context for understanding the origin and spatial distribution of cryptic diversity in a widespread Balkan freshwater amphipod Author(s): Michał Grabowski, Tomasz Mamos, Karolina Bącela-Spychalska, Tomasz Rewicz, Remi A. Wattier Abstract: The Balkans are a major biodiversity and endemism hotspot, worldwide. Among the freshwater biota, amphipods are known for their high cryptic diversity. However, little is known about the temporal and paleogeographic aspects of

Finding fossils is a fractal business

Fractals are not really new. I met them back in the early 90’s while trying to find answers to peculiarities of data series for a chapter of my PhD thesis. It was just before the release of the movie about the announced doom of (any) Jurassic Park, which popularized the scientific awareness that natural (non linear) systems are unpredictable, what is known as the deterministic chaos. Fractals are, lets say, the geometry

Small, shy, but plentiful of paleobiogeographic information

The paleontological record on shallow facies of the islands in the middle of a wide ocean such as the Atlantic allows to better understand the paleobiogeography of certain species, in particular those that have an amphi-Atlantic distribution. This is the case for small encrusting barnacles (you really need to pay attention to the surface of the fossil coral heads to spot them) of the genus Ceratoconcha. Ranging in age from the
