“…At the change from Pliocene to Pleistocene the temperature conditions were probably comparable to the present‐day conditions. The Megalopolis pollen‐association indicates a clearly cooler climate 1.6 Myr ago, probably related to the Euburon‐cold period of north‐western Europe (Benda et al ., 1987). This led to the successive vanishing of the thermophilic and humidophilic tertiary elements which were so characteristic for the vegetation composition before (Hesselbarth et al ., 1995).…”

This study points out the evidence of a hybrid zone between two groups of genetically differentiated populations of chestnut (Castanea sativa Mill.) in Turkey. Genetic structure, gene flow and introgression levels, based on 16 allozyme loci, were investigated on 34 population samples spanning the entire C. Sativa distribution area in this country. The occurrence of the hybrid zone, located in the Bithynian region, was inferred in a group of populations showing the following genetic characteristics: (i) enhanced genetic variability and intermediate allelic frequencies between those of the Western and Eastern groups of populations; (ii) shall, and concordant changes in allele frequencies; (iii) decreased gene flow with the Western and Eastern populations. Starting from the dine width estimated to be 324 km, strength of selection was evaluated from the gene Bow distance, as indicated from the degree of genetic structuring outside the hybrid zone. Evolutionary processes shaping the observed genetic differentiation and introgression are discussed on the basis of palynological data, palaeoclimatic events and evidence of hybridization found in other plant and animal species in the same region

“…The faunal composition of the Apolakkia Formation suggests that it was formed during the Middle and Late Ruscinian, i.e., about 5.3-3.4 Ma (Van de weerd et al 1982;Benda et al 1987), an age determination that was recently corroborated by a palaeomagnetic study (Van hInsBerGen et al 2007).…”

Well-preserved fossil eggs and eggshell fragments from the Pliocene Apolakkia Formation of Rhodes (Greece) are described. The eggs were found in-situ in a clutch. They are sub-spherical with lengths of 53-60 mm and widths of about 40 mm. All eggs are diagenetically compressed and their original diameters are estimated at 45-50 mm. The eggshells are 0.3-0.5 mm thick, partly recrystallized, but widely still aragonitic. They consist of needle-like crystals that form individual shell units. A few pores are preserved between these shell units. This shell-structure allows assignment to chelonian eggs in the oofamily Testudoolithidae and the oogenus Testudolithus. The external morphology, microstructure and mineralogical composition of the eggshells show close resemblance to eggs of the extant tortoise Geochelone elephantopus. Together with a small association of turtle carapace fragments from the same formation, the clutch represents the first discovery of turtle and reptilian remains from the Pliocene of the island of Rhodes.

“…The transition from Microtus (Allophaiomys) to Microtus (Microtus) species marks the transition between the Early and the Late Biharian and the Mimomys -Arvicola transition during the early Middle Pleistocene marks the end of the Biharian and the beginning of the Toringian (e.g., Fejfar and Heinrich, 1981;Tesakov, 2004). Benda et al (1987) In order to resolve the debate on the stratigraphical position of the Marathousa Member, Doukas and colleagues sampled the Marathousa Member in 1995 at a section exposed at Choremiou. The lowermost Lignite Seam I, the base of Lignite Seam II and Lignite Seam III yielded botanical as well as faunal remains; mammalian fossils are, however, not very abundant (Van Vugt, 2000;Doukas and Papayianni, 2016).…”

The lacustrine deposits exposed at the Lower Palaeolithic site Marathousa 1 (Megalopolis, S. Greece) and intercalated between lignite Seam II and III yielded a collection of small vertebrate remains. The assemblage includes fish and small mammals; the mammal assemblage encompasses a variety of species, dominated by voles (arvicolids) of the genera Arvicola and Microtus. Other rodents are represented by a dipod cf. Alactaga and a murid of the genus Apodemus. In addition, there is a number of insectivore remains that refer to the family Soricidae, and more specifically to the genus Crocidura. The unrooted Arvicola molars show a positive'Mimomys' enamel differentiation with a mean SDQ value of 122, indicating a late Middle Pleistocene age (ca. 400 ka.) (MIS 12/11). The Marathousa 1 assemblage is clearly younger than the Choremi assemblages sampled ca. 20 years ago in the same basin. In the Choremi assemblage, Mimomys, the predecessor of the genus Arvicola, is the predominant arvicolid.
