Quantifying foraminiferal growth with high-resolution X-ray computed tomography: New opportunities in foraminiferal ontogeny, phylogeny, and paleoceanographic applications KU Leuven Universiteit Gent
The latest generation of high-resolution X-ray computed tomography (HRXCT), with a submicron resolution, enables for the first time three-dimensional (3D) imaging and biometric quantification of foraminiferal interiors. Here we exemplify the basic possibilities and opportunities of this new technique by means of an analysis on a fossil specimen of Pseudouvigerina sp. from the basal Paleocene of the Brazos River, Texas. The total scan consists of ...
Convergent evolution associated with habitat decouples phenotype from phylogeny in a clade of lizards Universiteit Antwerpen
Convergent evolution can explain similarity in morphology between species, due to selection on a fitness-enhancing phenotype in response to local environmental conditions. As selective pressures on body morphology may be strong, these have confounded our understanding of the evolutionary relationships between species. Within the speciose African radiation of lacertid lizards (Eremiadini), some species occupy a narrow habitat range (e. g. open ...
Genomic variation in next-generation sequencing data: from human Y chromosomal phylogeny to insect genomics KU Leuven
In the past decade next-generation sequencing (NGS) technologies have revolutionized the fields of molecular biology, genetics and genomics by enabling cost-effective and quick generation of DNA sequence data with exquisite accuracy and resolution. The technical strategy of the NGS technology is straightforward: the sequencing throughput is boosted by miniaturizing the sequencing chemical reactions such that millions of those reactions can take ...
Pairwise learning for predicting pollination interactions based on traits and phylogeny Universiteit Gent
Mutualistic bee-plant interaction networks are a vital part of terrestrial ecosystems. They frequently arise through co-evolutionary processes, which match the traits of both partners, facilitating their interaction. Insights in these interaction mechanisms are vital to be able to manage changing ecosystems. This entails the need for models to predict species interaction networks in general and pollination networks in particular. We show how ...
Study of three interesting species of Amanita from Thailand based on multiple gene phylogeny and toxin analysis Plantentuin Meise / Agentschap Plantentuin Meise
Amanita ballerina and A. brunneitoxicaria spp. nov. are introduced from Thailand. Amanita fuligineoides is also reported for the first time from Thailand, increasing the known distribution of this taxon. Together, those findings support our view that many taxa are yet to be discovered in the region. While both morphological characters and a multiple-gene phylogeny clearly place A. brunneitoxicaria and A. fuligineoides in sect. Phalloideae (Fr.) ...
Molecular phylogeny of the Cladophoraceae (Cladophorales, Ulvophyceae), with the resurrection of Acrocladus Nägeli and Willeella Børgesen, and the description of Lurbica gen. nov. and Pseudorhizoclonium gen. nov Plantentuin Meise / Agentschap Plantentuin Meise Universiteit Gent
The taxonomy of the Cladophoraceae, a large family of filamentous green algae, has been problematic for a long time due to morphological simplicity, parallel evolution, phenotypic plasticity and unknown distribution ranges. Partial large subunit (LSU) rDNA sequences were generated for 362 isolates, and the analyses of a concatenated dataset consisting of unique LSU and small subunit (SSU) rDNA sequences of 95 specimens greatly clarified the ...
Seeing the wood for the trees: a minimal reference phylogeny for the human Y chromosome KU Leuven
During the last few decades, a wealth of studies dedicated to the human Y chromosome and its DNA variation, in particular Y-chromosome single-nucleotide polymorphisms (Y-SNPs), has led to the construction of a well-established Y-chromosome phylogeny. Since the recent advent of new sequencing technologies, the discovery of additional Y-SNPs is exploding and their continuous incorporation in the phylogenetic tree is leading to an ever higher ...
A plastid DNA phylogeny of tribe Miliuseae : insights into relationships and character evolution in one of the most recalcitrant major clades in Annonaceae Universiteit Gent KU Leuven
Premise of the study: Tribe Miliuseae (similar to 25 genera and similar to 510 species) includes a substantial part of the species and generic diversity in the pantropical flowering-plant family Annonaceae (similar to 108 genera and similar to 2400 species). Previous molecular phylogenetic analyses have failed to resolve the backbone phylogeny of the tribe, impeding biogeographical and evolutionary studies. We use a dense generic taxon sample ...
Taxonomy and phylogeny of Koinocystididae (Platyhelminthes, Kalyptorhynchia), with the description of three new genera and twelve new species Koninklijke Maatschappij voor Dierkunde van Antwerpen Universiteit Hasselt
The taxon Koinocystididae is the third most species-rich family within Eukalyptorhynchia. However, its diversity and phylogeny have been largely neglected in former studies. We introduce three new genera and twelve new species of Koinocystididae including Simplexcystis asymmetrica gen. n. sp. n., Galapagetula cubensis sp. n., eight species of Reinhardorhynchus gen. n. and two species of Itaipusa. This raises the total number of species within ...
