We mapped 15 morphological and 5 bionomical characters on the SSU rDNA tree, which was constructed to cover all known phylogenetic groups of myxosporeans.
The analyses of character evolution of 15 morphological and 5 bionomical characters show the evolution of individual characters and uncover the main evolutionary changes in the myxosporean spore morphology and bionomy.
Tracing the evolution of particular characters facilitated the reconstruction of the evolution of the myxospores' morphology and bionomical characters.
arabiensis maintain many distinct genetic and bionomical features and are taxonomically considered good species under most species concepts.
Careful assessment of morphological and molecular data in a redescription of A flagellum, in a parallel study also led by White, strongly suggested that populations in the north-west Pacific were not A flagellum but a second and new species.
"It gives me another chance to absolutely thrash my sister," says Stephen, 12. His specialised subject is morphological and behavioural mimicry in arthropods – spiders being sneaky, basically – in which he scores a very creditable 15 points.
Until more extensive morphological and genetic studies are completed, the researchers have opted to apply the designation E.S.U., evolutionary significant unit, a reproductively isolated population that is important to the species' evolution.
Yet forest elephant advocates aren't likely to drop the question anytime soon, especially as they say the weight of both morphological and genetic data is on their side.
These morphological and immunohistochemical features indicate PEComa.
