Cyanobacteria are major contributors to global biogeochemical cycles. The genetic diversity among Cyanobacteria enables them to thrive across many habitats. However, the taxonomy of Cyanobacteria remains unstable because of an inadequate taxonomic classification...

Aims. Mountain ranges in the tropics are characterised by high levels of localised endemism, often-aberrant evolutionary trajectories, and some of the world’s most diverse regional biotas. Here we investigate the evolution of montane endemism, ecology and body...

During the 19th and 20th century eponyms have been widely used in taxonomy to honour collectors of material on which new taxa have been based. Also have new taxa been dedicated to author-colleagues. Five cases are discussed to trace the extend of overlap between...

We present a new supertree method that enables rapid estimation of a summary tree on the scale of millions of leaves. This supertree method summarizes a collection of input phylogenies and an input taxonomy. We introduce formal goals and criteria for such a supertree...

Binary matrix with a priori defined plesiomorphic character‐state may be re-­written as a simple set of branching diagrams (as a “Hennigian forest”). The last might be analyzed by the average consensus method. This procedure eventually avoids the taxon-­‐character...

We herein examine the only known non-planispirally coiled early Devonian ammonoid, the holotype specimen of Ivoites opitzi, to investigate if the host was encrusted in vivo and if these sclerobionts were responsible for the trochospiral coiling observed on this...
