Ancestral role of Pax2/5/8 in molluscan brain and multimodal sensory system development
Wollesen, Tim; Rodríguez Monje, Sonia V; Todt, Christiane; Degnan, Bernard M; Wanninger, Andreas (Peer reviewed; Journal article, 2015-10-28)Background Mollusks represent the largest lophotrochozoan phylum and exhibit highly diverse body plans. Previous studies have demonstrated that transcription factors such as Pax genes play important roles during their ... -
Aplacophoran mollusks evolved from ancestors with polyplacophoran-like features
Scherholz, Maik; Redl, Emanuel; Wollesen, Tim; Todt, Christiane; Wanninger, Andreas (Peer reviewed; Journal article, 2013-11-04)Mollusca is an animal phylum with vast morphological diversity and includes worm-shaped aplacophorans, snails, bivalves, and the complex cephalopods [1]. The interrelationships of these class-level taxa are still contentious ... -
Comparative neuroanatomy suggests repeated reduction of neuroarchitectural complexity in Annelida
Heuer, Carsten M.; Müller, Carsten H.G.; Todt, Christiane; Loesel, Rudi (Peer reviewed; Journal article, 2010-05-04)Background Paired mushroom bodies, an unpaired central complex, and bilaterally arranged clusters of olfactory glomeruli are among the most distinctive components of arthropod neuroarchitecture. Mushroom body neuropils, ... -
The complete mitochondrial genome of Scutopus ventrolineatus (Mollusca: Chaetodermomorpha) supports the Aculifera hypothesis
Osca, David; Irisarri, Iker; Todt, Christiane; Grande, Cristina; Zardoya, Rafael (Peer reviewed; Journal article, 2014-09-25)Background: With more than 100000 living species, mollusks are the second most diverse metazoan phylum. The current taxonomic classification of mollusks recognizes eight classes (Neomeniomorpha, Chaetodermomorpha, ... -
Development of the nervous system in Solenogastres (Mollusca) reveals putative ancestral spiralian features
Redl, Emanuel; Scherholz, Maik; Todt, Christiane; Wollesen, Tim; Wanninger, Andreas (Peer reviewed; Journal article, 2014-12-24)Background: The Solenogastres (or Neomeniomorpha) are a taxon of aplacophoran molluscs with contentious phylogenetic placement. Since available developmental data on non-conchiferan (that is, aculiferan) molluscs mainly ... -
Diversity of Caudofoveata (Mollusca) Around Iceland and Description of Psilodens Balduri sp. n.
Mikkelsen, Nina Therese; Todt, Christiane (Peer reviewed; Journal article, 2014)The first records from samples from the IceAGE cruise ME85/3 in 2011 include seven species of Caudofoveata with a distribution range in Icelandic waters. From this first cruise of the project, two new records for Iceland ... -
Fast evolving 18S rRNA sequences from Solenogastres (Mollusca) resist standard PCR amplification and give new insights into mollusk substitution rate heterogeneity
Meyer, Achim; Todt, Christiane; Mikkelsen, Nina T.; Lieb, Bernhard (Peer reviewed; Journal article, 2010-03-09)Background: The 18S rRNA gene is one of the most important molecular markers, used in diverse applications such as molecular phylogenetic analyses and biodiversity screening. The Mollusca is the second largest phylum within ... -
Fauna associated with non-native Sargassum muticum (Fucales, Phaeophyceae) vary with thallus morphology and site type (sounds and bays)
Sjøtun, Kjersti; Armitage, Caroline Susanne; Eilertsen, Mette; Todt, Christiane (Journal article; Peer reviewed, 2021)The invasive brown alga Sargassum muticum was first recorded in Norway in 1988 and is presently common in the sublittoral fringe on the sheltered coast in South Norway. Here, results from a study on mesofauna associated ... -
From complex to simple: myogenesis in an aplacophoran mollusk reveals key traits in aculiferan evolution
Scherholz, Maik; Redl, Emanuel; Wollesen, Tim; Todt, Christiane; Wanninger, Andreas (Peer reviewed; Journal article, 2015-09-18)Background Recent studies suggest a bifurcation at the base of Mollusca, resulting in the primarily single-shelled Conchifera (Bivalvia, Gastropoda, Scaphopoda, Monoplacophora, Cephalopoda) and the spicule-bearing Aculifera ... -

Of tests, trochs, shells, and spicules: Development of the basal mollusk Wirenia argentea (Solenogastres) and its bearing on the evolution of trochozoan larval key features
Todt, Christiane; Wanninger, Andreas (Peer reviewed; Journal article, 2010-01-26)Background The phylogenetic status of the aplacophoran mollusk taxon Solenogastres (Neomeniomorpha) is controversially discussed. Some authors propose the clade to represent the most basal branch within Mollusca, while ... -
Phylogenomics of Aplacophora (Mollusca, Aculifera) and a solenogaster without a foot
Kocot, Kevin M.; Todt, Christiane; Mikkelsen, Nina Therese; Halanych, Kenneth M (Peer reviewed; Journal article, 2019)Recent molecular phylogenetic investigations strongly supported the placement of the shell-less, worm-shaped aplacophoran molluscs (Solenogastres and Caudofoveata) and chitons (Polyplacophora) in a clade called Aculifera, ...
