The fossil fallow deer <Emphasis Type="Italic">Dama geiselana</Emphasis> (Cervidae,Mammalia, upgrade to species level) in the context of migration and local extinctions of fallow deer in the Late and Middle Pleistocene in Europe

The fossil fallow deer Dama dama geiselana Pfeiffer from Neumark-Nord (Saxony-Anhalt, Germany) is upgraded to species level and discussed within the current taxonomy of recent and fossil fallow deer. Typical antler and skeletal characteristics are discussed in comparison with the recent Dama dama, Dama mesopotamica and the fossil species Dama clactoniana, Dama nestii and Dama rhenana. The phylogenetic relationship of fallow deer can be traced back to the Late Pliocene and distinguished morphologically from Cervus elaphus, Cervus nippon and Axis axis. Late and Middle Pleistocene finds from Germany are presented and discussed in the context of the finds from the Mediterranean region and Great Britain. The differences in antler morphology and bone dimensions in West German and North-East German fallow deer from the Late Pleistocene support the hypothesis of different immigration channels, on the one hand from the eastern Mediterranean along the Danube and on the other from the west along the Rhone and Rhine. In the Middle Pleistocene, Dama mesopotamica is considered as the typical fallow deer in the eastern Mediterranean, while in the west, Dama clactoniana is widespread. The hypothesis of immigration from the eastern Mediterranean is supported by the fossil record in Germany with the fallow deer from Edesheim. Conversely, Dama geiselana probably influenced East Mediterranean populations. Special tooth characteristics of Dama geiselana occur with lower frequency in Dama mesopotamica. In the Bronze Age, the fallow deer from Kastanas (Macedonia) shares antler characteristics, the high frequency of specific features of the scapula, and the astragalus with Dama geiselana. A relict population of Dama geiselana probably reached the Eastern Mediterranean at the beginning of the last cold stage.     

New Occurrences of Flying Fishes <Emphasis Type="Italic">Cheilopogon melanurus</Emphasis> and <Emphasis Type="Italic">C. heterurus</Emphasis> (Exocoetidae) in the North Central Atlantic and Eastern Part of the Mediterranean Sea

Cheilopogon melanurus, found for the first time in the central part of the North Atlantic (26°34′6 N 33°55′2 W), and C. heterurus from the eastern part of the Mediterranean Sea (Mahmutlar, Alanya, Turkey) are described. C. heterurus is widely distributed in the eastern part of the Mediterranean Sea occurring here in all seasons.     

Notes on the Occurrence of <Emphasis Type="Italic">Oligonychus milleri</Emphasis> (McGregor) and <Emphasis Type="Italic">Oligonychus ununguis</Emphasis> (Jacobi) (Acari: Tetranychidae) in Brazil

We verified infestation of Oligonychus milleri (McGregor) on plantations of Pinus caribaea (Pinaceae) and of Oligonychus ununguis (Jacobi) on plantations of Eucalyptus urophylla x Eucalyptus grandis (Myrtaceae) in State of Rondônia, Northern region of Brazil. This represents the first record of O. milleri in Brazil. Oligonychus ununguis was recorded previously, on cypress. The damage caused by these two spider mites in the plantations is described herein.     

The beginnings of rye (<Emphasis Type="Italic">Secale cereale</Emphasis>) cultivation in the East Baltics

In this paper we review the earliest Secale (rye) records, both pollen and macroremains, from the eastern Baltic region (northeast Poland, Lithuania, Latvia, Estonia and Finland) in order to understand the processes evident in the beginnings of rye cultivation. By taking note of the abundance of recovered Secale grains and pollen in relation to other cereals found in published archaeobotanical data, we try to understand when rye began to be used regionally as a staple food. The clarification of the timing of Secale in the East Baltic, that had social and economic implications, is of particular importance. In this publication we also present a radiocarbon date directly derived from dating a Secale grain from a Roman period hillfort in Lithuania. The date obtained constitutes the earliest record of Secale in the eastern Baltic region, showing that rye cultivation traditions and concomitant innovations in agricultural technology started there much earlier than previously suggested.     

Phylogeography of the Ibero-Maghrebian red-eyed grass snake (<Emphasis Type="Italic">Natrix astreptophora</Emphasis>)

We examined phylogeographic differentiation of the red-eyed grass snake (Natrix astreptophora) using 1984 bp of mtDNA and 13 microsatellite loci from specimens collected across its distribution range in southwestern Europe and northwestern Africa. Based on phylogenetic analyses of mtDNA, European N. astreptophora constituted the sister clade to a weakly supported North African clade comprised of two deeply divergent and well-supported clades, one corresponding to Moroccan snakes and the other to snakes from Algeria and Tunisia. This tripartite differentiation was confirmed by analyses of microsatellite loci. According to a fossil-calibrated molecular clock, European and North African N. astreptophora diverged 5.44 million years ago (mya), and the two Maghrebian clades split 4.64 mya. These dates suggest that the radiation of the three clades was initiated by the environmental changes related to the Messinian Salinity Crisis and the reflooding of the Mediterranean Basin. The differentiation of N. astreptophora, with distinct clades in the Iberian Peninsula and in the western and eastern Maghreb, corresponds to a general phylogeographic paradigm and resembles the differentiation found in another co-distributed Natrix species, the viperine snake (N. maura). Despite both species being good swimmers, the Strait of Gibraltar constitutes a significant biogeographic barrier for them. The discovery that North Africa harbours two endemic lineages of N. astreptophora necessitates more conservation efforts for these imperilled snakes.     

When invasion biology meets taxonomy: <Emphasis Type="Italic">Clavelina oblonga</Emphasis> (Ascidiacea) is an old invader in the Mediterranean Sea

Taxonomic issues often confound the study of invasive species, which sometimes are unrecognized as introduced in newly colonized areas. Clavelina oblonga Herdman, 1880 is an abundant ascidian species along the southeastern coast of the United States and the Caribbean Sea. It was introduced into the eastern Atlantic and Brazil decades ago. In the Mediterranean Sea, a similar species had been described as C. phlegraea Salfi 1929 and reported from southern Italy and Corsica. In the last few years a species of Clavelina has proliferated in the embayments of the Ebro Delta (NW Mediterranean), a zone of active bivalve culture industry where it has smothered mussel spat, leading to economic loss. We here report the morphological and genetic identity of this species, synonymizing the Atlantic C. oblonga and the Mediterranean C. phlegraea (the latter therefore is a synonym of the former). Thus, C. oblonga has existed in the Mediterranean for over 80 years, but was known under a different name. We also found this species in natural habitats in the Iberian Atlantic coast close to the Strait of Gibraltar, raising concerns about an ongoing expansion. In order to obtain information relevant for management, we monitored growth, reproductive cycles and settlement patterns of this ascidian on bivalve cultures in the Ebro Delta. Its biological cycles were markedly seasonal, with peak abundance and reproduction during the warmest months, followed by regression during the cold season. The settlement period was short, mostly concentrated in a single month each year. Avoidance of mussel and oyster seeding during late summer and early autumn can readily reduce the damage caused by this species.     

First Record of the Subgenus <Emphasis Type="Italic">Empis</Emphasis> (<Emphasis Type="Italic">Planempis</Emphasis>) (Diptera,Empididae) from Middle Asia,with Description of a New Species

A new species of the subgenus Planempis Frey, 1953 (Diptera: Empididae), Empis (Planempis) gussakovskiisp. n., is described from Tajikistan, being the first record of the subgenus from Middle Asia. The relationships of the new species within the subgenus Planempis are shortly discussed. An updated check-list of Planempis species is provided.     

Conservation genetics of the short-beaked common dolphin (<Emphasis Type="Italic">Delphinus delphis</Emphasis>) in the Mediterranean Sea and in the eastern North Atlantic Ocean

Mediterranean Sea common dolphins have recently been listed as ‘endangered’ in the IUCN Red list, due to their reported decline since the middle of the 20th century. However, little is know about the number or distribution of populations in this region. We analysed 118 samples from the Black Sea, Mediterranean Sea and eastern North Atlantic at nine microsatellite nuclear loci and for 428 bps of the mtDNA control region. We found small but significant population differentiation across the basin between the eastern and the western Mediterranean populations at both nuclear and mtDNA markers (microsatellite F _ST = 0.052, mtDNA F _ST = 0.107, P values ≤ 0.001). This matched the differential distribution and habitat use patterns exhibited by this species in the eastern and the western parts of the Mediterranean Sea. The assignment test of a small number of samples from the central Mediterranean could not exclude further population structure in the central area of the basin. No significant genetic differentiation at either marker was observed among the eastern north Atlantic populations, though the Alboran population (inhabiting the Mediterranean waters immediately adjacent the Atlantic ocean) showed significant mtDNA genetic differentiation compared to the Atlantic populations. Directional estimates of gene flow suggested movement of females out of the Mediterranean, which may be relevant to the population decline. Phylogenetic analysis suggested that the observed population structure evolved recently.     

Late Cretaceous (Santonian-Campanian) sea lilies (Echinodermata,Crinoidea) from the glacial rafts of northwestern Poland

Seven Santonian (Isocrinus? minutus, Tetracrinus jagti, Cyathidium senessei, Bourgueticrinidae indet., Notocrinidae indet., Glenotremites paradoxus, Marsupites testudinarius) and seven Campanian (Nielsenicrinus carinatus, Austinocrinus sp., Bourgueticrinidae indet., Bourgueticrinus cf. constrictus, B. ellipticus, B.? suedicus, Roveacrinina gen. et sp. indet.) crinoid taxa from the Cretaceous glacial rafts of northwestern Poland (near Wolin Island) are described for the first time. The taphonomy and palaeogeographic implications are discussed. The present assemblage differs taxonomically from the crinoid faunules recently described from the glacial rafts of eastern Poland. However, these faunules are similar to crinoids from the autochthonous Upper Cretaceous sediments of southern and eastern Poland (Miechów Trough, Kraków-Cz?stochowa Upland, Middle Vistula River valley). An update of Late Cretaceous crinoids from the Miechów Trough and Kraków-Cz?stochowa Upland is also given.     

Historical biogeography and mitogenomics of two endemic Mediterranean gorgonians (Holaxonia,Plexauridae)

Among the Mediterranean plexaurids, four species are endemic and despite their ecological importance, comprehensive studies on the evolution and biogeography of these organisms are lacking. Here, we explore the mitogenomic variability of two endemic, ecologically important Mediterranean Paramuricea species. We assess their phylogenetic relationships and provide first insights into their evolution and biogeography. Complete mitogenome sequences of Paramuricea clavata and Paramuricea macrospina were obtained using long-range PCR, primer-walking and Sanger sequencing. For an enlarged sample of Paramuricea species, maximum likelihood and Bayesian phylogenetic trees of the mitochondrial gene mtMutS were obtained and used to study the biogeographic history of Paramuricea through a statistical Dispersal-Vicariance (S-DIVA) method and a Dispersal Extinction Cladogenesis (DEC) model. Divergence time was estimated under strict and relaxed molecular clock models in BEAST using published octocoral mutation rates. Our results revealed high nucleotide diversity (2.6%) among the two Mediterranean endemics; the highest mutation rates were found in the mtMutS, Nad4 and Nad5. In addition, we found length polymorphisms in several intergenic regions and differences in mitochondrial genome size. The red gorgonian P. clavata was closely related to the Eastern Atlantic Paramuricea grayi rather than its Mediterranean congener, P. macrospina. Our biogeographic results provide evidence for the independent speciation of the Mediterranean species and point to a Miocene origin of the two endemics, highlighting the role played by the Messinian Salinity Crisis in the evolutionary history of Mediterranean organisms.     

A re-evaluation of diversity of the Aporocotylidae Odhner, 1912 in <Emphasis Type="Italic">Siganus fuscescens</Emphasis> (Houttuyn) (Perciformes: Siganidae) and associated species

The aporocotylid fauna of the mottled spinefoot, Siganus fuscescens (Houttuyn), from Moreton Bay, Queensland, Australia, was characterised using a combined morphological and molecular approach. Four aporocotylid species were identified, three belonging to the genus Ankistromeces Nolan & Cribb, 2006 and one to Cardicola Short, 1953. Specimens of Cardicola matched an undescribed species from the same host and locality; this species is described as Cardicola mogilae n. sp. Phylogenetic analyses of ITS2 and 28S data showed that C. mogilae n. sp. forms a strongly supported clade with other Cardicola species from siganid fishes. We record Ankistromeces olsoni Nolan & Cribb, 2006 in Moreton Bay for the first time, redescribe A. dunwichensis Nolan & Cribb, 2006 on the basis of new specimens and sequence data and re-report Ankistromeces sp. X from Moreton Bay based on molecular data. We review the status of the ten putative species of aporocotylids reported from siganids. Small variation in ITS2 rDNA sequences, in association with different geographic localities, was previously used to separate Cardicola lafii Nolan & Cribb, 2006 from C. parilus Nolan & Cribb, 2006, C. bartolii Nolan & Cribb, 2006 from C. watsonensis Nolan & Cribb, 2006, C. tantabiddii Nolan & Cribb, 2006 from Cardicola sp. 2, Ankistromeces sp. Y from A. olsoni and Ankistromeces sp. X from Ankistromeces sp. Z. These five combinations are reinterpreted as each representing a single species; Cardicola lafii is recognised as the senior synonym of C. parilus and C. bartolii as the senior synonym of C. watsonensis. This study thus suggests that six, rather than ten, species should be recognised as infecting S. fuscescens. This richness remains greater than is known for any other fish species and siganids are, so far, unique among fishes in harbouring two strongly radiated lineages of aporocotylids.     

Evidence for diversification of <Emphasis Type="Italic">Calophyllum</Emphasis> L. (Calophyllaceae) in the Neogene Siwalik forests of eastern Himalaya

Here, we report fossil leaves, woods, and pollen grains comparable to Calophyllum L. (mainly to Calophyllum inophyllum L. and Calophyllum polyanthum Wall. ex Choisy) of Calophyllaceae from the upper (Kimin Formation, late Pliocene-early Pleistocene), middle (Subansiri Formation, Pliocene) Siwalik sediments of the Arunachal sub-Himalaya, and lower (Gish Clay Formation of Sevok Group; middle to late Miocene) Siwalik sediments of the Darjeeling foothills, eastern Himalaya. Their presence indicates a warm and humid tropical environment in the region during the period of Siwalik sedimentation. Considering all records of Calophyllum, it is suggested that Calophyllum was a frequent forest element throughout the period of Siwalik sedimentation during the Neogene (Miocene time). At present, C. polyanthum grows in the eastern Himalaya, but C. inophyllum is totally absent from north-eastern regions suggesting differential adaptability of these taxa to changing ecoclimatic conditions. Distinct climate change in the area, possibly related to the Himalayan Orogeny during Miocene–Pleistocene times, might have caused the disappearance of C. inophyllum from the entire eastern Himalaya and north-east Indian plains and a move to littoral/coastal and swampy forests of India and other adjoining south-east Asian regions, Polynesia, and the east coast of Africa. The past global distribution of Calophyllum is also discussed, and it is suggested that India may have been its primary centre of origin. This is the first time Cenozoic fossil leaves Calophyllum siwalikum Khan, R.A.Spicer & Bera, sp. nov. comparable to C. inophyllum are described using the both macro- and micromorphological characters.     

Confirmed occurrence of the Cusk-eel <Emphasis Type="Italic">Ophidion barbatum</Emphasis> (Osteichthyes: Ophidiidae) from the Coast of Tunisia (Central Mediterranean)

This paper reports the second record but also the first substantiated record of cusk-eel Ophidion barbatum (Linnaeus, 1758) from the northern coast of Tunisia, 168 mm in total length and weighing 18.3 g. The specimen is described including morphometric measurements and counts. Differences from its close relative species O. rochei (Linnaeus, 1758) are pointed out that confirm the occurrence of O barbatum in the Tunisian waters. This finding constitutes the northernmost extension range of the species in the area.     

A new species of <Emphasis Type="Italic">Trichodina</Emphasis> Ehrenberg, 1830 (Ciliophora: Trichodinidae) infecting farmed <Emphasis Type="Italic">Clarias gariepinus</Emphasis> (Burchell) (Siluriformes: Clariidae) in Cuba

A new species of Trichodina Ehrenberg, 1830 collected from the skin and fins of farmed North African catfish Clarias gariepinus (Burchell) fingerlings, is described. The new species can be distinguished from other trichodinids by the characteristics of the adhesive disc, especially by the great number of denticles. Trichodina merciae n. sp. is morphologically similar to T. renicola (Mueller, 1931) and T. marplatensis Martorelli, Marcotegui & Alda, 2008, in the number of denticles, but differs in the morphometric data, denticle morphology, environment and location. Trichodina merciae n. sp. has broad sickle-shaped blades and thin, straight rays, while T. marplatensis has broad club-shaped blades and wide S-shaped rays. Besides, denticle length, blade length, ray length, width of central part and denticle span of the new species are greater than T. marplatensis. However, the diameter of denticle ring and the diameter of the central area in T. marplatensis is larger than the ones in T. merciae n. sp. This is the first record of freshwater ectoparasite trichodinid with an average number of denticles greater than 50.     

The carnivoran community from the Miocene of Sandelzhausen (Germany)

From the Bavarian Early/Middle Miocene (MN5) site Sandelzhausen, nine species of carnivoran mammals are identified including the hemicyonine ursid Hemicyon stehlini, the amphicyonids Amphicyon cf. major and Pseudarctos bavaricus, the mustelids Ischyrictis zibethoides and Martes cf. munki, the mephitid Proputorius pusillus, the viverrid Leptoplesictis cf. aurelianensis, the felid Pseudaelurus romieviensis, and finally the recently described barbourofelid Prosansanosmilus eggeri. With these taxa present, Sandelzhausen shows a carnivoran community typical, though deprived, for the Lower to Middle Miocene of Europe, but different from roughly contemporary Mediterranean faunas such as those from Çandir or Pa?alar in Turkey.     

Vertebrates from the Pontian of the Shkodova Gora locality (Northwestern Black Sea Region,Upper Miocene)

Remains of fishes, turtles, birds, and mammals are described from the Upper Miocene (MN13) Shkodova Gora locality (Ukraine, Odessa Region), the only representative locality of Pontian large vertebrates in the northwestern Black Sea Region. Asiatic fish and avian taxa are recorded for the first time in the Upper Miocene of Europe. The Shkodova Gora ichthyofauna includes eight freshwater fish species (belonging to Acipenseridae, Cyprinidae, Siluridae, and Percidae). Taxa that have previously been recorded only in Western Siberia (Abramis bliccoides, Perca lepidopoma), eastern Kazakhstan, and the Altai Mountain (Rutilus tungurukensis) are revealed. Acipenser gueldenstaedtii is recorded for the first time in the Upper Miocene of Eastern Europe. The occurrence of the genus Ctenopharyngodon, a member of the Chinese plain faunal assemblage is of great interest. The Shkodova Gora avifauna (seven taxa) is mostly composed of waterfowl, including Phalacrocorax mongoliensis, which has previously been known only from the Lower Pliocene of Mongolia. The finding of Proanser major is the youngest record of this species in the fossil record. Mammals of the Shkodova Gora association include a hare resembling Trischizolagus dumitrescuae, Palaeoryx cf. pallasi, and Hipparion cf. moldavicum, which have not been mentioned among Pontian taxa of the northern Black Sea Region. Pontian paleolandscapes in the area of the Shkodova Gora locality are reconstructed.
