Late Pleistocene and Early Holocene finds from Öküzini : A Contribution to the Settlement History of the Bay of Antalya, Turkey.

The results from a sounding in 1989 in the cave of Öküzini are described. They add to the finds from the neighbouring cave Karain В and extend our knowledge of the settlement history in the Antalya region into the early Holocene. While at 12,500 (' C) years bp Karain was used only as a hunting site, Öküzini at the same time shows signs of more heavily utilised plant resources. A variable use of the area the sites is interpreted.Les résultats d'un sondage effectué en 1989 dans la grotte ď Öküzini — présentés ici— apportent, avec les travaux récents dans la grotte voisine de Karain В, une contribution à la connaissance du peuplement de la région ď Antalya jusqu'au début de l'Holocène. Alors que vers 12 500 BP Karain servait uniquement de station de chasse, Öküzini témoigne d'une utilisation plus grande des ressources végétales. La région semble alors avoir été exploitée en fonction des saisons.Albrecht Gerd, Albrecht B., Berke H., Burger D., Moser J., Rähle W., Schoch W., Storch G., Uerpmann Hans-Peter, Urban B.

Insect phylogenomics: results, problems and the impact of matrix composition

In this study, we investigated the relationships among insect orders with a main focus on Polyneoptera (lower Neoptera: roaches, mantids, earwigs, grasshoppers, etc.), and Paraneoptera (thrips, lice, bugs in the wide sense). The relationships between and within these groups of insects are difficult to resolve because only few informative molecular and morphological characters are available. Here, we provide the first phylogenomic expressed sequence tags data (‘EST’: short sub-sequences from a c(opy) DNA sequence encoding for proteins) for stick insects (Phasmatodea) and webspinners (Embioptera) to complete published EST data. As recent EST datasets are characterized by a heterogeneous distribution of available genes across taxa, we use different rationales to optimize the data matrix composition. Our results suggest a monophyletic origin of Polyneoptera and Eumetabola (Paraneoptera + Holometabola). However, we identified artefacts of tree reconstruction (human louse Pediculus humanus assigned to Odonata (damselflies and dragonflies) or Holometabola (insects with a complete metamorphosis); mayfly genus Baetis nested within Neoptera), which were most probably rooted in a data matrix composition bias due to the inclusion of sequence data of entire proteomes. Until entire proteomes are available for each species in phylogenomic analyses, this potential pitfall should be carefully considered
