Fish as diet resource in North Spain during the Upper Paleolithic

During the last glacial maximum, the west European modern humans adapted to adverse conditions and their populations subsisted exploiting the natural resources available. Fish were always present as a source of animal protein, although their importance in the human diet and their contribution to the expansion of humans has not been fully explored. Based on the compilation of zooarchaeological evidences from north Spanish sites we have discovered a constant pattern of exploitation of freshwater fish (Salmonids) with high incidence in the human diet during the Upper Paleolithic. Shifts in the exploitation of marine resources can be explained by climate-related geographical changes. The characteristics of salmonids that make them target species for supporting human survival in adverse climate periods are identified and discussed.

Agriculture and exploitation of wild plants at Chalcolithic (4th to 3rd millennium cal BC) sites in Sardinia (Italy)

This paper present the results of archaeobotanical analysis carried out at two open-air sites dated to the first phase of the Copper Age, “Chalcolithic” (4th to 3rd millennium cal BC) in Sardinia. The sediment was systematically floated, a total of 3142 l was sampled and 4014 charred plant remains were identified. Chalcolithic agriculture in Sardinia was primarily based on the cultivation of Hordeum vulgare, H. vulgare var. nudum and Triticum aestivum/durum. Possible cultivated legumes of Vicia/Lathyrus, Vicia/Pisum and cf. Pisum sativum were identified. Linum sp. was also present, which may have been cultivated and exploited in Sardinia by the Chalcolithic community. The diet of the Chalcolithic community was complemented by the consumption of edible fruits such as Ficus carica, Sambucus sp. and Vitis vinifera subsp. sylvestris. Typical Mediterranean shrubs such as Pistacia lentiscus, Juniperus sp., Cistus sp., Malva sp. and Thymelaea hirsuta were also found.     

Does international recognition matter? Support for unilateral secession in Catalonia and Scotland

How much do the prospects of international recognition of a possible new state affect the domestic support for secession? To answer this research question, we adopted a most similar systems design and conducted a Web‐based survey experiment in Catalonia and Scotland. Respondents were presented with plausible scenarios regarding the international recognition of a hypothetical independent state by other countries and were subsequently asked whether they would support a unilateral declaration of independence. The results show that the prospects of international recognition as a sovereign and independent state influence the degree of support for a unilateral declaration of independence in both cases. This effect was moderated by the intensity of nationalist sentiment and the motivations for independence. Respondents with more outspoken nationalist sentiments were only marginally influenced by these scenarios or treatments. Moreover, participants whose preferences towards secession were driven by ethno‐political motivations were less influenced by international factors than those who wanted an independent state for economic or political reasons.     

New tools for rock art modelling: automated sensor integration in Pindal Cave

This paper presents the integration of automated sensors based on a terrestrial laser scanner and an amateur digital camera with the aim of generating a photorealistic three-dimensional (3D) model of the Principal Panel in Pindal Cave (Spain). The approach developed for 3D modelling overcomes many of the problems related to the independent implementation of photogrammetry and laser scanning. Particularly, a sequential and hierarchical approach was developed based on the processing and matching of images from the camera (camera image) and the laser scanner (range image). The results obtained demonstrate that the workflow for this model is automatic, effective, and accurate. The presented approach was found to create hyper-realistic models, even improving upon human visual capabilities.     

How diverse were early animal communities? An example from Ediacara Conservation Park,Flinders Ranges,South Australia

Coutts, F.J., Gehling, J.G. & García-Bellido, D.C., August 2016. How diverse were early animal communities? An example from Ediacara Conservation Park, Flinders Ranges, South Australia. Alcheringa 40, xxx–xxx. ISSN 0311-5518

Fossils of the Ediacara biota record the earliest evidence of animal communities and, as such, provide an invaluable glimpse into the abiotic and biotic processes that helped shape the evolution of complex life on Earth. A diverse community of Ediacaran macro-organisms is preserved with high resolution in a fossil bed recently excavated from north Ediacara Conservation Park (NECP) in the Flinders Ranges, South Australia. Many of the commonly described Ediacaran taxa from the Flinders Ranges are represented on the bed surface and include: Parvancorina, Rugoconites, Spriggina, Dickinsonia, Tribrachidium, Kimberella, Charniodiscus and Yorgia, including two new taxa. Numerous additional fossil-bed fragments from the same locality were analysed that preserve a similar suite of taxa and shared sedimentology. On all surfaces, preserved microbial mat appeared complex, both in topography and in texture, and the unique combination of fine grainsize, high diversity and trace fossils provide insights into the palaeoecology of the ancient organisms that lived during the Ediacaran Period some 550 Ma. Several trace fossils are overlapped by body fossils, indicative of successive events, and complex organismal behaviour. The complexity of this fossil surface suggests that the primordial community was relatively mature and possibly at late-stage succession.

Phylogenetic analysis of the Panochthini (Xenarthra,Glyptodontidae), with remarks on their temporal distribution

Zamorano, M. & Brandoni, D., 2013. Phylogenetic analysis of the Panochthini (Xenarthra, Glyptodontidae), with remarks on their temporal distribution. Alcheringa 37, 1–10. ISSN 0311-5518.

To test the monophyly of Panochthini, a phylogenetic analysis including all the species traditionally referred to the tribe was conducted. The matrix included 16 species of Glyptodontidae and 35 characters, from which 14 correspond to the skull, four to the dentition, two to the cephalic armour, nine to the dorsal carapace and six to the caudal sheath. Propalaehoplophorus australis (Propalaehoplophorinae) was used to root the trees. Four most parsimonious trees were obtained (Tree Length = 75, CI = 0.65, RI = 0.70). The strict consensus tree (Tree Length = 77, CI = 0.64, RI = 0.68) has the following topology: Propalaehoplophorus australis (Glyptodon reticulatus (Hoplophorus euphractus (Panochthus jaguaribensis, P. intermedius (P. frenzelianus, P. tuberculatus (P. subintemedius, P. greslebini)))) ((Pseudoplohophorus absolutus, Plohophorus figuratus) (Nopachtus cabrerai, N. coagmentatus, Propanochthus bullifer, Stromaphorus compressidens, Phlyctaenopyga ameghini))). The results indicate that: 1, Panochthini is not a natural group but polyphyletic; 2, Panochthus is monophyletic and, concordant with recent proposals, Hoplophorus euphractus is its sister group; and 3, Nopachtus and Propanochthus are more closely related to species traditionally referred to ‘Plohophorini’ than to Panochthus. Nopachtus and Propanochthus, as the ‘Plohophorini’, are recorded from the latest part of the Neogene, whereas Panochthus and Hoplophorus euphractus are restricted to the Quaternary.

Terrestrial laser scanning intensity data applied to damage detection for historical buildings

This paper presents a methodology to combine the technology of the terrestrial laser scanner with the techniques of digital image processing in order to study damages on stony materials that constitute historical buildings. This methodology has been tested using intensity data from three terrestrial laser scanners with different technical specifications. The unsupervised classification algorithms were used for the classification of 2D intensity images derived from the 3D information obtained from laser scanner equipment. The results obtained show the potential of the use of intensity data from terrestrial laser scanner for the recognition and characterization of certain pathologies in building materials that constitute historical buildings.     

Populism,Hegemony, and the Politics of Natural Resource Extraction in Evo Morales's Bolivia

Is populism necessary to the articulation of counter‐hegemonic projects, as Laclau has long argued? Or is it, as ?i?ek maintains, a dangerous strategy, which inevitably degenerates into ideological mystification and reactionary postures? In this paper, I address this question by exploring the politics of discourse in Evo Morales's Bolivia. While, in the years leading to the election of Morales, a populist ideological strategy was key to challenging neoliberal forces, once the hegemony of the new power bloc was stabilised, indigenous demands for emancipatory socio‐environmental change began to be perceived as a threat to resource‐based accumulation. In this context, the populist signifiers that originated in indigenous‐popular struggles were used by the Morales government to legitimise repression of the indigenous movement. I argue, therefore, that ideological degeneration signals a problem not with populism per se, but rather with the class projects and shifting correlations of forces that underpin it in changing conjunctures.
