Morphology, molecular phylogenetics and biogeography of Impatiens akomensis (Balsaminaceae), a new species from Cameroon Meise Botanic Garden KU Leuven
Background and aims – A recent field expedition in the Campo-Ma'an/Akom II region in Cameroon resulted in the collection of a previously unknown Impatiens species, which resembles Impatiens macroptera and Impatiens pseudomacroptera. This study aims to describe and infer the evolutionary history of this novelty by using phylogenetics, biogeographic inference and dating estimation analyses.
Methods – The new species was subject to a ...

Molecular phylogenetics reveal multiple tertiary vicariance origins of the African rain forest trees Meise Botanic Garden Ghent University
Background: Tropical rain forests are the most diverse terrestrial ecosystems on the planet. How this diversity evolved remains largely unexplained. In Africa, rain forests are situated in two geographically isolated regions: the West-Central Guineo-Congolian region and the coastal and montane regions of East Africa. These regions have strong floristic affinities with each other, suggesting a former connection via an Eocene pan-African rain ...
Molecular phylogenetics of the genus Costularia (Schoeneae, Cyperaceae) reveals multiple distinct evolutionary lineages Meise Botanic Garden Ghent University
We investigated the monophyly of Costularia (25 species), a genus of tribe Schoeneae (Cyperaceae) that illustrates a remarkable distribution pattern from southeastern Africa, over Madagascar, the Mascarenes and Seychelles, to Malesia and New Caledonia. A further species, Tetraria borneensis, has been suggested to belong to Costularia. Relationships and divergence times were inferred using an existing four marker phylogeny of Cyperaceae tribe ...
Molecular phylogenetics and generic assessment in the tribe Pavetteae (Rubiaceae) Meise Botanic Garden KU Leuven
This is the first phylogenetic study focused on the Pavetteae, one of the most species-rich and morphologically diverse tribes within the coffee family (Rubiaceae). Fifteen of the 17 currently recognized genera, represented by 85 taxa, were sequenced for rps16, trnT-F and ITS and analysed using Bayesian inference and maximum likelihood methods. The monophyly of the Pavetteae is confirmed. Four major lineages are identified, but their ...
Morphometrics and molecular phylogenetics of Angraecum section Dolabrifolia (Orchidaceae, Angraecinae) Meise Botanic Garden
Species delimitation within Angraecum section Dolabrifolia is problematic due to morphological variability coupled with overlap in many of the characters traditionally used to distinguish species. Recent molecular phylogenetic studies of the genus included three of the five currently described species of the Dolabrifolia group, placing them as sister to continental African species of Angraecum sect. Pectinaria. In preparation for a taxonomic ...
A global view of Gyroporus: molecular phylogenetics, diversity patterns, and new species Meise Botanic Garden
Gyroporus (Gyroporaceae, Boletales) is a highly diverse genus of poroid ectomycorrhizal mushrooms with a nearly worldwide distribution. Previous attempts to unravel the diversity within this genus proved difficult due to the presence of semicryptic species and ambiguous results from analysis of ribosomal RNA markers. In this study, we employ a combined morphotaxonomic and phylogenetic approach to delimit species and elucidate geographic and ...
Extended molecular phylogenetics and revised systematics of Malagasy scincine lizards Ghent University
Accurate Model Selection of Relaxed Molecular Clocks in Bayesian Phylogenetics KU Leuven
Recent implementations of path sampling (PS) and stepping-stone sampling (SS) have been shown to outperform the harmonic mean estimator (HME) and a posterior simulation-based analog of Akaike's information criterion through Markov chain Monte Carlo (AICM), in Bayesian model selection of demographic and molecular clock models. Almost simultaneously, a Bayesian model averaging approach was developed that avoids conditioning on a single model but ...
Molecular phylogenetics and biogeography of the Old World true freshwater crabs, with emphasis on the fauna of Sri Lanka Hasselt University
With about 6,800 species described , the Brachyura or true crabs are the most species-rich group of Decapoda, such as lobsters, crabs and shrimp (Ng et al. 2008; De Grave et al. 2009). An astonishing one fifth ("'1280 species) of those crabs are true freshwater Gecarcinucoidea, Potamoidea, (Cumberlidge et al., 2008). crabs, belonging Pseudothelphusoidea to four superfamilies: and Trichodactyloidea During the past twenty years, freshwater crab ...
