Inter-population variation and phenotypic plasticity in kairomone use by a poly-specialist spider-eating predator
Previous research on Cyrba algerina (Araneae, Salticidae) has shown this jumping spider expresses predatory specialisation with respect to spiders as prey as well as inter-population variation in
Eukaryotic Genomes Show Strong Evolutionary Conservation of k-mer Composition and Correlation Contributions between Introns and Intergenic Regions
It is concluded that all of these conserved patterns between IIRs indicate a shared function of these sequence structures related to STRs, and specific preferences for certain nucleotides stable over all four phylogenetic kingdoms are found.
Origins of eukaryotic excitability
The ancestral repertoire of eukaryotic excitability is described and five major cellular innovations that enabled its evolutionary origin are discussed, including a vastly expanded repertoire of ion channels, the emergence of cilia and pseudopodia, endomembranes as intracellular capacitors, a flexible plasma membrane and the relocation of chemiosmotic ATP synthesis to mitochondria.


Macroevolution of complex cytoskeletal systems in euglenids
By possessing combinations of characters resulting from adaptive change and morphostasis, euglenids have retained key pieces of evidence necessary for reconstructing the early evolution and diversification of eukaryotic life.
Microbial arms race: Ballistic “nematocysts” in dinoflagellates represent a new extreme in organelle complexity
The diversity of traits in dinoflagellate nematocysts demonstrates a stepwise route by which simple secretory structures diversified to yield elaborate subcellular weaponry.
Predatory colponemids are the sister group to all other alveolates
The phylogenomic analyses of 313 eukaryote protein-coding genes from transcriptomes of three members of one such group, the colponemids, unambiguously support their monophyly and position as the sister lineage to all other alveolates.
Cascades of convergent evolution: The corresponding evolutionary histories of euglenozoans and dinoflagellates
It is suggested that the excessive complexity of euglenozoan and alveolate gene expression, organellar genome structure, and RNA editing and processing has been thoroughly debated and are more likely the products of constructive neutral evolution, and as such do not necessarily confer any selective advantage at all.
Ultrastructure and molecular phylogenetic position of a novel euglenozoan with extrusive episymbiotic bacteria: Bihospites bacati n. gen. et sp. (Symbiontida)
BackgroundPoorly understood but highly diverse microbial communities exist within anoxic and oxygen-depleted marine sediments. These communities often harbour single-celled eukaryotes that form
Morphostasis in a novel eukaryote illuminates the evolutionary transition from phagotrophy to phototrophy: description of Rapaza viridis n. gen. et sp. (Euglenozoa, Euglenida)
The marine mixotrophic mode of nutrition, the preference for green algal prey cells, the structure of the feeding apparatus, and the organization of the pellicle are outstanding examples of morphostasis that clarify pivotal stages in the evolutionary history of this diverse group of microbial eukaryotes.
Hunting for agile prey: trophic specialisation in leptophryid amoebae (Vampyrellida, Rhizaria) revealed by two novel predators of planktonic algae

Trophic specialisation in leptophryid amoebae (Vampyrellida) and their strategies to prey on planktonic algae are revealed and euglenoid movements exerted by the sluggish species of the ‘Euglena deses group’ may serve as an effective defence against microbial predators.
