Evolutionary biology of harvestmen (Arachnida, Opiliones).
Opiliones are one of the largest arachnid orders, with more than 6,500 species in 50 families. Many of these families have been erected or reorganized in the last few years since the publication of The Biology of Opiliones. Recent years have also seen an explosion in phylogenetic work on Opiliones, as well as in studies using Opiliones as test cases to address biogeographic and evolutionary que...
متن کاملAn occurence records database of French Guiana harvestmen (Arachnida, Opiliones)
This dataset provides information on specimens of harvestmen (Arthropoda, Arachnida, Opiliones) collected in French Guiana. Field collections have been initiated in 2012 within the framework of the CEnter for the Study of Biodiversity in Amazonia (CEBA: www.labex-ceba.fr/en/). This dataset is a work in progress. Occurrences are recorded in an online database stored at the EDB laboratory after ...
متن کاملParental investment and the evolution of subsocial behaviour in harvestmen (Arachnida Opiliones)
The diversity of reproductive strategies within the arachnids rivals all other arthropod groups. However, with the possible exception of spiders and scorpions, evolutionary biologists have overlooked these organisms. The order Opiliones is divided in three suborders (Cyphophthalmi, Palpatores and Laniatores) with considerable differences in morphology, habits and behaviour. In this review we fo...
متن کاملPhylogenetic Analysis of Phalangida (arachnida, Opiliones) Using Two Nuclear Protein-encoding Genes Supports Monophyly of Palpatores
Recent phylogenetic studies of Opiliones have shown that Cyphophthalmi and Phalangida (5 Palpatores 1 Laniatores) are sister groups, but higher relationships within Phalangida remain controversial. Current debate focuses on whether Palpatores (5 Caddoidea 1 Phalangioidea 1 Ischyropsalidoidea 1 Troguloidea) is monophyletic or paraphyletic, with Ischyropsalidoidea 1 Troguloidea (5 Dyspnoi) being ...
متن کاملOpiliones are no longer the same--on suprafamilial groups in harvestmen (Arthropoda: Arachnida).
A review of the names used in the arachnid order Opiliones above superfamily level is presented. Many historical branching patterns of Opiliones (for five terminals), of Laniatores (for six terminals), and of Cyphophthalmi (for six terminals) are extrapolated, compared and graphically displayed. For the first time a historical review is made of the circumscriptions of those names and comparison...
