Data from: Nature of the optical band shapes in polymethine dyes and H-aggregates: dozy chaos and excitons. Comparison with dimers, H*- and J-aggregates

Vladimir V. Egorov
Results on the theoretical explanation of the shape of optical bands in polymethine dyes, their dimers and aggregates are summarized. The theoretical dependence of the shape of optical bands for the dye monomers in the vinylogous series in line with a change in the solvent polarity is considered. A simple physical (analytical) model of the shape of optical absorption bands in H-aggregates of polymethine dyes is developed based on taking the dozy-chaos dynamics of the...

Data from: The genus Gennadas (Benthesicymidae: Decapoda): morphology of copulatory characters, phylogeny and coevolution of genital structures

Alexander L. Vereshchaka, Anastasia A. Lunina & Jørgen Olesen
Species within Gennadas differ from each other largely only in male (petasma) and female (thelycum) copulatory characters, which were restudied in scanning electron microscopy and used as a basis for phylogenetic analyses. Twenty-six petasma characters and 49 thelycum characters were identified. All sixteen recognized species of Gennadas and Aristaeomorpha foliacea (outgroup) were included as terminals. Four robust monophyletic clades were retrieved, described and diagnosed as new species groups. The thelycum characters had greater impact on...

Data from: Genetic barcoding of dark-spored myxomycetes (Amoebozoa)—Identification, evaluation and application of a sequence similarity threshold for species differentiation in NGS studies

Mathilde Borg Dahl, Asker D. Brjenrod, Martin Unterseher, Thomas Hoppe, Yun Feng, Yuri Novozhilov, Søren J. Sørensen, Martin Schnittler & Asker D. Brejnrod
Unicellular, eukaryotic organisms (protists) play a key role in soil food webs as major predators of microorganisms. However, due to the polyphyletic nature of protists, no single universal barcode can be established for this group, and the structure of many protistean communities remains unresolved. Plasmodial slime moulds (Myxogastria or Myxomycetes) stand out among protists by their formation of fruit bodies, which allow for a morphological species concept. By Sanger sequencing of a large collection of...

Data from: Novel predators reshape holozoan phylogeny and reveal the presence of a two-component signalling system in the ancestor of animals

Elisabeth Hehenberger, Denis V. Tikhonenkov, Martin Kolisko, Javier Del Campo, Anton S. Esaulov, Alexander P. Mylnikov & Patrick J. Keeling
Our understanding of the origin of animals has been transformed by characterizing their most closely related, unicellular sisters: the choanoflagellates, filastereans, and ichthyosporeans. Together with animals, these lineages make up the Holozoa [ 1, 2 ]. Many traits previously considered “animal specific” were subsequently found in other holozoans [ 3, 4 ], showing that they evolved before animals, although exactly when is currently uncertain because several key relationships remain unresolved [ 2, 5 ]. Here...
