Revision of non-Passeriform birds from Polgárdi (Hungary,Late Miocene): 1. Anseriformes

Polgárdi is a series of Late Miocene localities in central Hungary, which have yielded one of the richest Miocene avifaunas. The taxonomic composition of the waterfowl (Anseriformes) from Polgárdi is revised. As a result of revision, Anas denesi Kessler, 2013 is transferred to the genus Aythya. This species has a combination of primitive and advanced morphological characters, which do not come in conflict with the concept of gradual formation of morphological features of the modern type in various lineages of Aythya. Another small duck from Polgárdi referred to as Anas albae Jánossy, 1979 is only possible to be identified as Mergini gen. indet.     

Revision of non-passeriform birds from Polgárdi (Hungary,Late Miocene): 2. Galliformes

A taxonomic revision of Galliformes (Aves) from the Upper Miocene of Polgárdi has confirmed the presence of five taxa. A large pheasant originally described as Pavo aesculapi phasianoides Jánossy, 1991 is referred to the genus Syrmaticus as a valid species, S. phasianoides (Jánossy, 1991), comb. nov. Small phasianids are represented in Polgárdi by four taxa: Mioryaba magyarica gen. et sp. nov., Eurobambusicola turolicus gen. et sp. nov., Plioperdix hungarica (Jánossy, 1991), and a form similar in size to Mioryaba magyarica, but having a more primitive structure of the tarsometatarsus and carpometacarpus.     

Phytoliths as a seasonality indicator? The example of the Neolithic site of Pendimoun,south-eastern France

Vegetation History and Archaeobotany - Pendimoun rock-shelter is among the oldest Neolithic sites known on the French littoral (Impressa culture, since ca. 5700 bce). It was discontinuously...     

Enrichment of dissimilatory Fe(III)-reducing bacteria from groundwater of the Siklós BTEX-contaminated site (Hungary)

Dissimilatory iron-reducing bacteria are commonly found in microbial communities of aromatic hydrocarbon-contaminated subsurface environments where they often play key role in the degradation of the contaminants. The Siklós benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated area is one of the best characterized petroleum hydrocarbon-contaminated sites of Hungary. Continuous monitoring of the microbial community in the center of the contaminant plume indicated the presence of an emerging Geobacter population and a Rhodoferax phylotype highly associated with aromatic hydrocarbon-contaminated subsurface environments. The aim of the present study was to make an initial effort to enrich Rhodoferax-related and other dissimilatory iron-reducing bacteria from this environment. Accordingly, four slightly different freshwater media were used to enrich Fe(III) reducers, differing only in the form of nitrogen source (organic, inorganic nitrogen or gaseous headspace nitrogen). Although enrichment of the desired Rhodoferax phylotype was not succeeded, Geobacter-related bacteria were readily enriched. Moreover, the different nitrogen sources caused the enrichment of different Geobacter species. Investigation of the diversity of benzylsuccinate synthase gene both in the enrichments and in the initial groundwater sample indicated that the Geobacter population in the center of the contaminant plume may not play a significant role in the anaerobic degradation of toluene.     

Fossil bats from the Late Pleistocene site of the Aguilón P7 Cave (Zaragoza,Spain)

Bats (Chiroptera, Mammalia) are a valuable and independent source of palaeoenvironmental information in Quaternary sites because bat assemblages are not necessarily produced by the same processes as those of other small mammals. Here, we report a small collection of bats (MNI 15) from a cave infill of the Aguilón P7 (AGP-7) site (Zaragoza, Spain) dated Late Pleistocene (MIS 3). This is one of the rare localities south of the Ebro River (right bank) with Neanderthal tracks; therefore, the palaeoenvironmental data provided here may help us to understand Neanderthal history. Nine bat taxa were identified, viz. Rhinolophus ferumequinum, R. hipposideros, Myotis gr. myotis/blythii, M. cf. bechsteinii, M. emarginatus, M. daubentonii, Plecotus gr. auritus/austriacus, Hipsugo savii vel. Pipistrellus kuhlii/nathusii, and Miniopterus schreibersii. The presence of a high number of yearlings of the former four species suggests the presence of breeding colonies. The surprisingly high diversity of the sample indicates a variegated vegetation cover and relatively high humidity for the MIS 3 stage in the region.     

A Valanginian crustacean microcoprolite ichnofauna from the shallow-marine hydrothermal vent site of Zengővárkony (Mecsek Mts., Hungary)

A rich and diverse crustacean microcoprolite ichnofauna is reported from the Valanginian of the Mecsek Mts., Hungary. Localities from the Bolondút and Dezső Rezső valleys near Zengővárkony (Eastern Mecsek Mts.) provided Favreina aff. dispentochetarius, Palaxius darjaensis, P. triochetarius, P. salataensis, P. tetraochetarius, and P. decaochetarius. They occur in limonitic and partly metasomatized limestones, limestone olistoliths, and ammonite body-chambers. The remarkable richness of this ichnofauna plus the previous records from the same environment (altogether 11 ichnospecies of four ichnogenera from a single stratigraphic level) make it the most diverse crustacean ichnofauna of the Mesozoic. The former ecosystem of the ichnofauna is considered a deeper shallow-marine (water depth <300 m) hydrothermal vent on which the producers of the microcoprolites lived. The related brachiopod fauna shows a remarkable size and is dominated by Lacunosella. This fauna is not similar to typical fossil deep-sea vent faunas; however, it offers a thorough understanding of other fossil shallow-marine hydrothermal vent faunas and the role of crustaceans in these ecosystems. This is the first record of crustacean coprolites from such a fossil site and documents that crustaceans were diverse and played an important role in shallow-marine, non photosynthesis-based ecosystems in the geological past.     

Evidence of ‘new glume wheat’ from the Late Neolithic (Copper Age) of south-eastern Hungary (4th millennium cal. b.c.)

In 2000, remains of an unknown Triticum species—later named ‘new glume wheat’ (NGW)—were identified in the archaeobotanical material of Neolithic and Bronze Age Greek sites. The presence of NGW was later reported from several other locations across Europe, from the seventh to the first millennium cal. b.c. During the systematic archaeobotanical survey of the multiperiod site of Hódmez?vásárhely–Kopáncs I., Olasz-tanya (5310–2936 cal. b.c.) more than 2,000 cereal remains were recovered. During the morphological analyses, ten spikelet forks showed the distinctive traits of NGW, therefore morphometric analyses were conducted on the remains to reinforce the morphological identification. The results suggest that both approaches—morphological and morphometric—should be applied in parallel to securely separate the NGW remains from Triticum turgidum L. ssp. dicoccum (Schrank) Thell. (emmer) and T. monococcum L. ssp. monococcum (einkorn). All NGW glume bases were recovered from Late Copper Age features (3338–3264 cal. b.c.) of the settlement, which represent the Baden culture of the Great Hungarian Plain. Similarly to other Baden culture sites of the Carpathian Basin einkorn and emmer dominated the crop production of the settlement. The ratio of the NGW remains within the cereal assemblage was measured to be 0.48 %, which suggests that NGW did not have the status of a regular crop; still it may have been part of the accompanying weed flora of the cereal fields during the fourth millennium in the south-eastern Great Hungarian Plain landscape.     

Insights into the earliest agriculture of Central Portugal: Sickle implements from the Early Neolithic site of Cortiçóis (Santarém)

Direct evidence of agriculture in Early Neolithic Portugal is almost non-existent, so there are very disparate estimates of the role played by agriculture during the period. Recent excavations at Cortiçóis, a newly discovered Early Neolithic site in central Portugal, revealed the first recognizable sickle implements and therefore relevant artefactual evidence of agricultural practices. These are typologically similar to Andalusian and Valencian sickles, reflecting a common technological tradition in southern Iberia during the period (c. 5600–4000 cal BC). Based on this fact, we summarize all available evidence for early agriculture in central Portugal and compare it with the Andalusian and Valencian records in order to tentatively present a model to be tested locally in future research.     

Revision of non-passeriform birds from Polgárdi (Hungary,Upper Miocene): 3. Neoaves

A taxonomic revision of Upper Miocene Neoaves from Polgárdi locality is summarized. Rallicrex polgardiensis is transferred to the genus Rallus. The taxonomic position of R. kolozsvarensis is discussed. Porzana estramosi veterior and P. kretzoii are transferred to the genus Zapornia former is ranked as species. It is shown that the material referred to Egretta polgardiensis, Surnia robusta, and Otis kalmani actually belong to the fossil barn owl Tyto campiterrae. The genera Cuculus and Tetrao are identified incorrectly and several other taxa cannot be identified to genus. A fragmentary carpometacarpus originally referred to as Gallinago veterior actually belongs to Glareolidae. A complete list of revised non-passeriform taxa from Polgárdi is provided and the composition of the avifauna is discussed. The absence of taxa shared with approximately contemporaneous avian assemblage from the Hyargas-Nuur 2 locality in eastern Mongolia is evidence that at least two separate zoogeographical units of temperate avifaunas existed in the Late Miocene of Eurasia.     

Assessing past agrobiodiversity of Prunus avium L. (Rosaceae): a morphometric approach focussed on the stones from the archaeological site H?tel-Dieu (16th century, Tours, France)

Abundant and diverse Prunus fruitstone remains from cherries, plums, sloes, peaches, etc. are frequently recovered from archaeological waterlogged contexts such as wells, latrines, lake dwellings etc. in Europe. The distinction between most of the Prunus species, based on traditional morphological characters of the fruit stones, is usually not problematic. However the discrimination between P. avium L., P. cerasus L. and related cherry species, based on classical criteria alone, often turns out to be ambiguous because of the increasing number of varieties which have been bred since Roman times. By combining geometric and traditional morphometrical approaches, the overall variation in shape and size of stones from French and Swiss excavations dating from the 1st century to the 16th century a.d. were assessed. Among these important archaeobotanical data, the detailed examination of 100 waterlogged stones from the 16th century H?tel-Dieu cesspit at Tours, France, revealed that the morphological diversity is structured into two distinct morphotypes which diverge mainly according to geometrical features. Finally, the comparison between morphological features of these well-preserved archaeological stones and modern reference material including P. avium, P. cerasus and P. × gondouinii, suggests that these two morphotypes, which have been initially attributed to P. avium (long stones) and P. avium/cerasus (rounded stones) according to traditional morphological parameters, would correspond to two different cultivated varieties, both belonging to Prunus avium. Results presented in this work constitute new and preliminary data obtained during the development of this project that throw light on morphological variability and biosystematic aspects.     

Charcoal analysis and the reconstruction of ancient woodland vegetation in the Konya Basin,south-central Anatolia,Turkey: results from the Neolithic site of Çatalhöyük East

The results produced by charcoal analysis are used in conjuction with pollen evidence, geomorphological data and ecological analogues, in order to reconstruct ancient woodland vegetation in the Konya Basin and its surroundings during the Neolithic. Emphasis is placed on the structure, diversity and seasonal habit of different vegetation types, as well as their potential response to natural and/or anthropogenic disturbance. It is argued that such an approach to vegetation reconstruction enables better insights into palaeoenvironments as experienced by human groups in the past, and thus offers fruitful avenues for investigating the relationship of human societies with the natural environment.

What’s in a hearth? Seeds and fruits from the Neolithic fishing and fowling camp at Bergschenhoek,The Netherlands,in a wider context

This paper presents new results from the Early Neolithic Dutch wetland site of Bergschenhoek (ca. 4200 cal b.c., Swifterbant Culture), which are compared with finds from similar features and sites. The data indicate the presence of predominantly eutrophic, nutrient-rich reed and forb vegetation and suggest the preparation of meals consisting of fish and fruits. The finds from the hearth, dominated by uncarbonised remains of wetland taxa, form a remarkable part of the find assemblage. Therefore, the discussion concerns assemblages, deposition processes and interpretations of uncarbonised and carbonised finds from hearths at comparable, contemporary sites. The wide variation of macroremains assemblages of hearths indicates that plant deposition in hearths is understood only partly and remains a topic for further research.     

A study of the carbonized seeds from a La Tène D1 rural settlement, “Le Camp du Roi” excavation at Jaux (Oise), France

This paper presents the results of the study of the macroscopic plant remains found in the granary of a La Tène D1 native farm situated on the plateau overlooking the river Oise, near Compiègne, northern France. The composition and the deposition of the harvest in the storage building are discussed. Some evidence of agricultural practices are deduced from the weeds associated with the grain.     

Late Neolithic agriculture in eastern Austria: archaeobotanical results from sites of the Baden and Jevišovice cultures (3600–2800 b.c.)

The article presents archaeobotanical results from six late Neolithic excavation sites in eastern Austria. Two of the sites belong to the Jevišovice culture (3200–2800 cal b.c.), the remaining four to the Baden culture (3600–2900 cal b.c.). Results show that farmers around 3000 cal b.c. were relying on the use of Triticum monococcum and Hordeum vulgare as principal cereals, with Triticum dicoccum and Panicum miliaceum as additional crops. Common millet was found in quantity at one of the Jevišovice sites and shows the remarkably early westward spread of this species. Single records of Triticum spelta are discussed in the light of the recently proposed ideas about an independent central European origin of spelt. Another record concerns the “new-type” glume wheat, providing further evidence for the once widespread occurrence of this cultivar. Triticum aestivum (hexaploid naked wheat) and Setaria italica (foxtail millet) were found as rare admixtures at the Jevišovice settlements. Pulses were represented by Pisum sativum and Lens culinaris, oil plants by Papaver somniferum and Linum usitatissimum. One of the Jevišovice sites offered a good opportunity for a study of the undisturbed spatial distribution of charred plant remains within a burnt house. Among wild plants, the occurrence of Stipa sp., Teucrium chamaedrys, Asperula cynanchica and Plantago media point to the presence of dry steppe grassland in the vicinity of the settlements, which was probably used for grazing. Woodland plants were mainly represented by fruit-bearing plants growing in clearings and forest edges, reflecting both the deliberate collection of wild fruits and the growing human impact on the vegetation.     

Spatial and temporal variations of meiofaunal communities from the western sector of the Gulf of Batabanó, Cuba: II. Seagrass systems

The meiofauna from seagrass meadows in the western sector of the Gulf of Batabanó, Cuba were studied to describe the spatial and temporal variations in community structure. Replicated cores were taken in three locations (arranged in m- and km-scales) and in two seasons (dry and wet). The meiofauna (metazoans between 500 and 45 microm) were identified to major taxa. Temporal changes in the meiofaunal communities could not be detected and they are not linked to the subtle seasonal changes in the water column. A larger variation in community structure was observed in the spatial m-scale (among cores in a station) probably accredited to heterogeneity of microenvironment and biological processes. A second source of variation in the km-scale (among locations) was identified relating to physical processes affecting seagrass meadows: marine currents and anthropogenic disturbances. Distribution patterns of meiofauna across locations coincide with one study from 20 years ago in seagrass beds (i.e. higher densities in area closer to break-shelf and diminution of fauna at southern of Pinar del Rio); however, cumulative anthropogenic disturbances on seagrass meadows would most likely explain the depletion of communities observed in our survey in comparison with decades ago. Estimates of meiofaunal density and richness of major taxa from our study (and other areas from the Cuban shelf) are consistently lower than other temperate and tropical sites; possibly caused by low primary productivity due to narrow tidal amplitude and oligotrophic waters.     

Myoretronectes paranaensis n. gen. et sp., a new freshwater genus of the family Retronectidae (Turbellaria, Catenulida) from the Paraná, Argentina

Myoretronectes paranaensis, gen. et sp. n., from lotic sandy bottoms of the Paraná river, Argentina, is described. The establishment of the new genus is based on the presence of a non-ciliated pharynx, a discrete oesophagus, and a strong muscle system surrounding the distal pharynx. A new emended diagnosis of the family Retronectidae is presented. Myoretronectes paranaensis apparently cohabits with the oligochaete Narapa bonettoi Righi & Varela, 1983 and the copepod Parastenocaris sp.
