Arthropod phylogeny revisited, with a focus on crustacean relationships.
Higher-level arthropod phylogenetics is an intensely active field of research, not least as a result of the hegemony of molecular data. However, not all areas of arthropod phylogenetics have so far received equal attention. The application of molecular data to infer a comprehensive phylogeny of Crustacea is still in its infancy, and several emerging results are conspicuously at odds with morpho...
متن کاملNeurogenesis in myriapods and chelicerates and its importance for understanding arthropod relationships.
Several alternative hypotheses on the relationships between the major arthropod groups are still being discussed. We reexamine here the chelicerate/myriapod relationship by comparing previously published morphological data on neurogenesis in the euarthropod groups and presenting data on an additional myriapod (Strigamia maritima). Although there are differences in the formation of neural precur...
متن کاملResolving arthropod relationships: Present and future insights from evo-devo studies
In the past two centuries, the field of arthropod phylogeny has been the subject of intense discussion. Traditionally, relationships based on morphology and fossil evidence of the four major arthropod lineages have suggested a closer relationship between myriapods and insects to the exclusion of crustaceans. It was also generally recognized that the chelicerates branched off as a basal group. H...
متن کاملEarly neurogenesis in the horseshoe crab Limulus polyphemus and its implication for arthropod relationships.
The relationships among the four arthropod groups (insects, crustaceans, myriapods, chelicerates) have been a point of controversy for many years. According to the traditional view, the myriapods are most closely related to the insects (common taxon “Tracheata” or Antennata), the crustaceans are the closest relatives of the Antennata (common taxon Mandibulata), and the chelicerates are the sist...
متن کاملARTHROPOD BIOLOGY Relationships Between Adult Abdominal Color and Reproductive Potential in Diaphorina citri (Hemiptera: Psyllidae)
Diaphorina citri Kuwayama (Hemiptera: Psyllidae), a vector of huanglongbing (citrus greening disease), exhibits threemore or less distinct abdominal colors in the adult stage: gray/brown, blue/green, and orange/yellow. A previous report showed that, relative to blue/green individuals, gray/brown individuals of both sexes have lower bodymass, and gray/brown females may have lower reproductive ou...
