Limnology and Aquatic Microbial Ecology of Byers Peninsula: A Main Freshwater Biodiversity Hotspot in Maritime Antarctica
2019
Here we present a comprehensive review of the diversity revealed by research in limnology and microbial ecology conducted in Byers Peninsula (Livingston Island, South Shetland Islands, Antarctica) during the last two decades. The site constitutes one of the largest ice-free areas within the Antarctic Peninsula region. Since it has a high level of environmental protection, it is less human-impacted compared to other sites within the South Shetland archipelago. The main investigations in Byers Peninsula focused on the physical and chemical limnology of the lakes, ponds, rivers, and wetlands, as well as on the structure of their planktonic and benthic microbial communities, and on the function…
The maternal genetic make-up of the Iberian Peninsula between the Neolithic and the Early Bronze Age
2017
Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500–3000 BCE), Chalcolithic (~ 3000–2200 BCE) and Early Bronze Age (~ 2200–1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions and thus on the largest archaeogenetic dataset from the Peninsula to date. Similar to other parts of Europe, we observe a discontinuity between hunter-gatherers and the first farmers of the Neol…
Survival of Late Pleistocene Hunter-Gatherer Ancestry in the Iberian Peninsula
2019
The Iberian Peninsula in southwestern Europe represents an important test case for the study of human population movements during prehistoric periods. During the Last Glacial Maximum (LGM), the peninsula formed a periglacial refugium [1] for hunter-gatherers (HGs) and thus served as a potential source for the re-peopling of northern latitudes [2]. The post-LGM genetic signature was previously described as a cline from Western HG (WHG) to Eastern HG (EHG), further shaped by later Holocene expansions from the Near East and the North Pontic steppes [3, 4, 5, 6, 7, 8, 9]. Western and central Europe were dominated by ancestry associated with the ∼14,000-year-old individual from Villabruna, Italy…
¿Una feria de cambios a la valenciana? Debate financiero y energía emprendedora en el siglo XVII
2020
In 1619 Philip IV sent to print a Real Pragmatic [Royal Pragmatic legislation] that would regulate changes between Valencia and Medina del Campo being introduced by Valencian merchant families to enable them to receive interest on their loans without being accused of usury. Only three years later, in 1622, the Republic of Genoa inaugurated the exchange fairs of Novi Ligure, with which the Genoese consolidated their international position in the international credit market. These apparently independent circumstances constitute an important episode for international financial knowledge and the transformation of the Mediterranean credit market during the seventeenth century. Studying financial…
Amphibians and squamate reptiles from the stratigraphic unit Xb of El Salt (Middle Palaeolithic; Alcoy, Spain): palaeoenvironmental and palaeoclimati…
2020
The locality of El Salt (Middle Paleolithic, Alcoy, Spain) is mainly known by having one of the youngest Neanderthals records of the southeastern Iberian Peninsula. In this work, we have analysed the herpetofaunal fossils from the upper part of stratigraphic unit Xb, dated at 52.3 ± 4.6 ka (MIS 3). The faunal list is composed by three taxa of anurans (Alyte obstetricans, Bufo bufo s.l., and Epidalea calamita), one taxon of blanid (Blanus cinereus s.l.), two taxa of lizards (Chalcides bedriagai and cf. Acanthodactylus erythrurus), and one taxon of snakes (cf. Rhinechis scalaris). All of them have a broad distribution range in the Mediterranean, with wide ecological preferences range. This as…
New Neandertal remains from Cova Negra (Valencia, Spain).
2005
New Neandertal fossils from the Mousterian site of Cova Negra in the Valencia region of Spain are described, and a comprehensive study of the entire human fossil sample is provided. The new specimens significantly augment the sample of human remains from this site and make Cova Negra one of the richest human paleontological sites on the Iberian Peninsula. The new specimens include cranial and postcranial elements from immature individuals and provide an opportunity to study the ontogenetic appearance of adult Neandertal characteristics in this Pleistocene population. Children younger than 10 years of age constitute four of the seven minimum number of individuals in the sample, and this rela…
Alternative Stories of Agricultural Origins: The Neolithic Spread in the Iberian Peninsula
2017
The spread of agriculture from the Near East to Europe has long been a subject of intense archaeological study and debate in light of the social and economic changes that occurred and were set in motion as a result of this transition. Despite the attention paid to this important process, a consensus is far from being reached. Perhaps for these reasons, new methods and theoretical approaches have often been applied to the questions surrounding the spread of agriculture first. Recently, computational modeling has emerged as a promising technique for the study of the origins of agriculture. Our approach employs an agent-based computational model of agricultural spread for the Iberian Peninsula…
The origins of agriculture in Iberia: a computational model
2015
Here we discuss the importance of using the rich and growing database of high-precision, audited radiocarbon dates for high-resolution bottom-up modelling to focus on problems concerning the spread of the Neolithic in the Iberia. We also compare the spread of the Late Mesolithic (so-called Geometric) and the Early Neolithic using our modelling environment. Our results suggest that the source of radiocarbon data used to evaluate alternative hypotheses plays an important role in the results and open up new lines of research for the future.
Nuevos datos sobre Ferula loscosii (Lange) Willk. (Apiaceae) en la provincia de Alicante
2012
Se amplía el área de distribución del endemismo ibérico Ferula loscosii en el noroeste de la provincia de Alicante, al haber sido hallados nuevos núcleos poblacionales situados a una distancia de hasta 4 km respecto al único núcleo anteriormente conocido en Villena. Asimismo se adjunta abundante material gráfico y descriptivo sobre las plantas alicantinas para facilitar tanto su comparación con el resto de poblaciones ibéricas como la futura detección de nuevas poblaciones de esta especie. The distribution area of the Iberian endemism Ferula loscosii is enlarged in NW Alicante province. New populations have been found which are located up to 4 km far from the single population currently kno…
Multi-model ensemble simulations of olive pollen distribution in Europe in 2014: current status and outlook
2017
"Çalışmada 29 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır” The paper presents the first modelling experiment of the European-scale olive pollen dispersion, analyses the quality of the predictions, and outlines the research needs. A 6-model strong ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run throughout the olive season of 2014, computing the olive pollen distribution. The simulations have been compared with observations in eight countries, which are members of the European Aeroallergen Network (EAN). Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimised c…
