Evolution of eumetazoan nervous systems: Insights from cnidarians
(Journal article; Peer reviewed, 2015-12-19)Cnidarians, the sister group to bilaterians, have a simple diffuse nervous system. This morphological simplicity and their phylogenetic position make them a crucial group in the study of the evolution of the nervous system. ... -
Evolution of the Pax-Six-Eya-Dach network: The calcisponge case study
(Journal article; Peer reviewed, 2014-06-23)Background: The Pax-Six-Eya-Dach network (PSEDN) is involved in a variety of developmental processes, including well documented roles in determination of sensory organs and morphogenesis in bilaterian animals. Expression ... -
Evolutionarily conserved aspects of animal nutrient uptake and transport in sea anemone vitellogenesis
(Journal article; Peer reviewed, 2022)The emergence of systemic nutrient transport was a key challenge during animal evolution, yet it is poorly understood. Circulatory systems distribute nutrients in many bilaterians (e.g., vertebrates and arthropods) but are ... -
Evolutionary and behavioral analysis of neuropeptides in bilaterians
(Doctoral thesis, 2017-06-29)Neuropeptides are a diverse group of neurosecretory signaling molecules that are utilized by the nervous system of all bilaterian animals. These signaling molecules are involved in most physiological processes and can play ... -
Evolutionary Implications of the microRNA- and piRNA Complement of Lepidodermella squamata (Gastrotricha)
(Journal article; Peer reviewed, 2019-02-22)Gastrotrichs—’hairy bellies’—are microscopic free-living animals inhabiting marine and freshwater habitats. Based on morphological and early molecular analyses, gastrotrichs were placed close to nematodes, but recent ... -
The Evolving Proteome of a Complex Extracellular Matrix, the Oikopleura House
(Peer reviewed; Journal article, 2012-07-05)Extracellular matrices regulate biological processes at the level of cells, tissues, and in some cases, entire multicellular organisms. The subphylum Urochordata exemplifies the latter case, where animals are partially or ... -

Exciting times to study the identity and evolution of cell types
(Journal article, 2019)The EMBO/EMBL Symposium on ‘The Identity and Evolution of Cell Types’ took place in Heidelberg, Germany, on 15-19 May 2019. The symposium, which brought together a diverse group of speakers addressing a wide range of ... -
Exonic remnants of whole-genome duplication reveal cis-regulatory function of coding exons
(Journal article; Peer reviewed, 2009-12-06)Using a comparative genomics approach to reconstruct the fate of genomic regulatory blocks (GRBs) and identify exonic remnants that have survived the disappearance of their host genes after whole-genome duplication (WGD) ... -

The Exploration of Ancient Stymphalos, 1982-2002
(Papers of the Norwegian Institute at Athens, Chapter, 2005)From 1982-84 the Canadian Archaeological Institute at Athens and the University of British Columbia in collaboration with the Archaeological Society of Athens carried out topographical and geophysical surveys of the site ... -
Expression of multiple Sox genes through embryonic development in the ctenophore Mnemiopsis leidyi is spatially restricted to zones of cell proliferation
(Journal article; Peer reviewed, 2014-04-24)Background: The Sox genes, a family of transcription factors characterized by the presence of a high mobility group (HMG) box domain, are among the central groups of developmental regulators in the animal kingdom. They are ... -
Expression of segment polarity genes in brachiopods supports a non-segmental ancestral role of engrailed for bilaterians
(Journal article; Peer reviewed, 2016-08-26)The diverse and complex developmental mechanisms of segmentation have been more thoroughly studied in arthropods, vertebrates and annelids—distantly related animals considered to be segmented. Far less is known about the ... -
Extreme Levels of Ocean Acidification Restructure the Plankton Community and Biogeochemistry of a Temperate Coastal Ecosystem: A Mesocosm Study
(Journal article; Peer reviewed, 2021)The oceans’ uptake of anthropogenic carbon dioxide (CO2) decreases seawater pH and alters the inorganic carbon speciation – summarized in the term ocean acidification (OA). Already today, coastal regions experience episodic ... -

Formulation of the planetary boundary layer feedback in the Earth´s climate system
(Journal article, 2008)Recent publications have revealed that the state-of-the-art climate models are probably not sensitive enough to observed changes in the surface air temperature. This fact calls for the search of feedback mechanisms making ... -
