Marine nematode taxonomy in the DNA age: the present and future of molecular tools to access their biodiversity Universiteit Gent
Molecular phylogeny and taxonomy of the Aegagropila clade (Cladophorales, Ulvophyceae), including the description of Aegagropilopsis gen. nov. and Pseudocladophora gen. nov Plantentuin Meise / Agentschap Plantentuin Meise Universiteit Gent
The Aegagropila clade represents a unique group of cladophoralean green algae occurring mainly in brackish and freshwater environments. The clade is sister to the species-rich and primarily marine Cladophora and Siphonocladus lineages. Phylogenetic analyses of partial LSU and SSU nrDNA sequences reveal four main lineages within the Aegagropila clade, and allow a taxonomic reassessment. One lineage consists of two marine Cladophora species, for ...
Morphological and molecular taxonomy of a new Daptonema (Nematoda, Xyalidae) with comments on the systematics of some related taxa Universiteit Gent
Linking morphological and molecular taxonomy for the identification of poultry house, soil, and nest dwelling mites in the Western Palearctic Universiteit Antwerpen Universiteit Hasselt
Because of its ability to expedite specimen identification and species delineation, the barcode index number (BIN) system presents a powerful tool to characterize hyperdiverse invertebrate groups such as the Acari (mites). However, the congruence between BINs and morphologically recognized species has seen limited testing in this taxon. We therefore apply this method towards the development of a barcode reference library for soil, poultry ...
Reverse taxonomy applied to the Brachionus calyciflorus cryptic species complex: Morphometric analysis confirms species delimitations revealed by molecular phylogenetic analysis and allows the (re) description of four species KU Leuven
The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly studied freshwater monogonont rotifer. By combining phylogenetic, morphometric and morphological analyses, we confirm the existence of four cryptic species that have been recently suggested by a ...
Disentangling taxonomy within the Rhabditis (Pellioditis) marina (Nematoda, Rhabditidae) species complex using molecular and morhological tools Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Correct taxonomy is a prerequisite for biological research, but currently it is undergoing a serious crisis, resulting in the neglect of many highly diverse groups of organisms. In nematodes, species delimitation remains problematic due to their high morphological plasticity. Evolutionary approaches using DNA sequences can potentially overcome the problems caused by morphology, but they are also affected by theoretical flaws. A holistic approach ...
Molecular taxonomy of **Crocidura** species (Eulipotyphla: Soricidae) in a key biogeographical region for African shrews, Nigeria Universiteit Antwerpen
The taxonomy of African shrew species is still unresolved due to their conserved morphology. This also affects knowledge concerning their geographic distribution. In Nigeria, using mitochondrial Cytochrome b gene sequences, we carried out a survey for shrews from the genus Crocidura across various ecological zones to determine taxa that are present and also to assess their phylogeographic structure. Our analyses include 183 specimens collected ...
Integrative taxonomy unravels cryptic diversity in the Paratrichodorus hispanus-group complex and resolves two new species of the genus and the molecular phylogeny of the family (Nematoda: Trichodoridae) Universiteit Gent
The genus Paratrichodorus currently comprises 26 species of polyphagous ectoparasitic plant nematodes that are distributed worldwide and include a few tobravirus vector species. Paratrichodorus is one of the most difficult genera for species identification because it is phenotypically conserved, with morphometric characters that often overlap between species. From 2003 to 2016, nematode surveys were conducted in southern Spain, and the present ...
Molecular phylogeny, taxonomy, and evolution of the land snail genus **Pyrenaearia** (Gastropoda, Helicoidea) Universiteit Antwerpen
We reconstructed the molecular phylogeny of 78 specimens, including nearly all nominal species of the genus Pyrenaearia, and discussed the implications of the molecular phylogeny for species delimitation. The four basal clades obtained by mitochondrial COI and 16S sequences were highly congruent with nuclear ITS markers, shell morphology, and geographic distribution patterns, and were considered different species under the phylogenetic species ...
