Molecular phylogeny of the Notostraca.
We used a combined analysis of one nuclear (28S rDNA) and three mitochondrial markers (COI, 12S rDNA, 16S rDNA) to infer the molecular phylogeny of the Notostraca, represented by samples from the six continents that are inhabited by this group of branchiopod crustaceans. Our results confirm the monophyly of both extant notostracan genera Triops and Lepidurus with good support in model based and...
متن کاملToward a Global Phylogeny of the “Living Fossil" Crustacean Order of the Notostraca
Tadpole shrimp (Crustacea, Notostraca) are iconic inhabitants of temporary aquatic habitats worldwide. Often cited as prime examples of evolutionary stasis, surviving representatives closely resemble fossils older than 200 mya, suggestive of an ancient origin. Despite significant interest in the group as 'living fossils' the taxonomy of surviving taxa is still under debate and both the phylogen...
متن کاملMolecular phylogeny of the Branchiopoda (Crustacea)--multiple approaches suggest a 'diplostracan' ancestry of the Notostraca.
The evolutionary history of Branchiopoda (Crustacea) traditionally has attracted considerable interest due to the diversity of the group. Recently molecular methods have been applied to the study of branchiopod systematics with some success, but central questions, such as the phylogenetic position of Laevicaudata and Notostraca, and the intrinsic cladoceran phylogeny, remain unanswered. We exam...
متن کاملKaryologic studies on cells from rabbit cornea and other tissues grown in vitro.
Individual layers of the cornea as well as lung tissues of rabbit were cultured separately in vitro. The endothelial and stromal cells of the cornea maintained their distinctive tissue culture morphology in serial subcultures for a period of over 20 months, and in the case of one endothelial line, even in passages after thatuing from storage at -79° C. These cell lines proved to be very suitabl...
متن کاملLuminous Phenomena of Earthquakes: Observations and Theories
Over the past few years, different theories (piezoelectric, positive holes, friction-vaporization, exo-electron emission, tribo- or fracture electrification) have been presented for the interpretation of earthquake lights. Although these theories can interpret earthquake luminous, each suffer from particular problems. There are also ambiguities and questions about the location of the light, the...
