Evidence of constant diversification punctuated by a mass extinction in the African cycads [PDF]

The recent evidence that extant cycads are not living fossils triggered a renewed search for a better understanding of their evolutionary history. In this study, we investigated the evolutionary diversification history of the genus Encephalartos, a ...

Wild cereals from Holocene central Sahara archaeological sites: aDNA and archaeobotany from the Takarkori rockshelter [PDF]

, 2014
Both pollen and macroremains recovered from archaeological sites point to a long-time exploitation of wild cereals and to the prevalence of these plants among those selected and transported to shelters and caves of central Sahara (southwestern Libya)(1).

DNA Barcoding for Taxonomic Resolution in Lamiaceae: Evaluating rbcL, matK, and trnH-psbA Markers for Species Identification

Abstract Lamiaceae family presents an example of the taxonomic complexities that challenge traditional identification methods. This study aimed to assay the effectiveness of three DNA barcoding markers (rbcL, matK, and trnH-psbA) for species identification within the genera Thymus, Mentha, and Salvia collected from various Egyptian locations ...
