Molecular phylogeny of the genus Chondrina (Gastropoda, Panpulmonata, Chondrinidae) in the Iberian Peninsula
2022
[EN] Chondrina Reichenbach, 1828 is a highly diverse genus of terrestrial molluscs currently including 44 species with about 28 subspecific taxa. It is distributed through North Africa, central and southern Europe, from Portugal in the West to the Caucasus and Asia Minor in the East. Approximately 70% of the species are endemic to the Iberian Peninsula constituting its main center of speciation with 34 species. This genus includes many micro endemic taxa, some of them not yet described, confined to limestone habitats (being strictly rock-dwelling species). They are distributed on rocky outcrops up to 2000 m.a.s.l. It is a genus of conical-fusiform snails that differ mainly in shell characte…
Listado taxonómico comentado de los Capitélidos (Annelida, Polychaeta) de la península Iberica, islas Chafarinas, Baleares y Canarias
2013
[EN] The present annotated checklist has been elaborated after revision of preserved materials (from the Museo Nacional de Ciencias Naturales, Madrid and the reference collection of the Marine Biology Laboratory of the University of Valencia) and published literature related to capitellids from the Iberian Peninsula, Chafarinas, Balearic and Canary Islands. Twenty-four species and subspecies belonging to thirteen genera are recognized as valid taxa. With this checklist we include some taxonomic details and information on distribution at both global and regional levels. This work includes the setal formula and diagrammatic representation of capitellid taxa treated in this study.
Timing the Mesolithic-Neolithic Transition in the Iberian Peninsula: The Radiocarbon Dataset
2019
In this paper, we describe the radiocarbon dataset compiled in the context of the project HAR2015-68962 EVOLPAST: Dinamicas evolutivas y patrones de variabilidad cultural de los ultimos cazadores-recolectores y el primer Neolitico en el este peninsular (7000–4500 cal. BC) funded by the Spanish government. The dataset offers the most complete and public radiocarbon dataset focus on the Neolithic Transition in the Iberian Peninsula. Funding statement: The data collection was funded by the Spanish Ministry of Economy, Industry and Competitiveness grant HAR2015-68962-P to Oreto Garcia Puchol & Joan Bernabeu. SPG is supported by Spanish Ministry of Economy, Industry and Competitiveness, Postdoct…
Soil Erosion on Mountain Trails in Eastern Iberian Peninsula
2020
A review on trial erosion shows that soil erosion rates are one to three orders of magnitude higher than the ones recommended as sustainable. This is threatening the sustainable managements of mountain terrains, mainly in the popular hiking paths. The warm temperatures characterize Eastern Spain in winter, which results in visitors from northern Europe to walk in the coastal land mountainous terrain. This increases the pressure to the currently highly visited most popular paths. We selected representative transects of the trails of Serra de Bérnia, Puigcampana, Penyagolosa, Montcabré, Serra del Sit, Aitana, Les Tres Creus, Caroig, Cupurutxo and Circ de la Safor. All the selected study sites…
Ramification of lithic production and the search of small tools in Iberian Peninsula Middle Paleolithic
2015
The notion of recycling and it relationship with ramified productions and small tool production in Late Middle Paleolithic from the Iberian Peninsula are investigated. Results from Amalda, Axlor, Pen~a Miel, and Quebrada show that the production of small tools is one of the principal objectives of lithic provi- sioning in these sites. Whereas in Axlor and Amalda, this is achieved through the ramification of pro- duction, due to the remoteness of flint sources, in Quebrada, where raw material sources are closer, small flakes are obtained at the end of Levallois production. The implications for Neandertal society organi- zation of this small tool production is discussed, and its evolution is …
Novedades sobre taxonomía y nomenclatura de híbridos vasculares españoles
1990
The nomenclature of some Iberian hybrids is revised and several new combinations are proposed: <i>Centaurea X subdecurrens</i> var. segobricensis, C.</i> X <i>subdecurrens</i> notbosubsp. <i>albuferae, Cistus</i> X <i>hybridus</i> nothosubsp. <i>grandiflorus</i> var. <i>secallianus. C.</i> X <i>ledon</i> var. <i>recognitus, C. </i>X <i>nigricans</i> var. <i>longifolius, C.</i> X <i>nigricans</i> nothosubsp. <i>grosii</i> and <i>Onopordum</i> X <i>humile</i> var. <i>turolensis</i>. Besides, a new nothosubspec…
Tillage Versus No-Tillage. Soil Properties and Hydrology in an Organic Persimmon Farm in Eastern Iberian Peninsula
2020
There is an urgent need to implement environmentally friendly agriculture management practices to achieve the Sustainable Goals for Development (SDGs) of the United Nations by 2030. Mediterranean agriculture is characterized by intense and millennia-old tillage management and as a consequence degraded soil. No-Tillage has been widely examined as a solution for soil degradation but No-Tillage relies more on the application of herbicides that reduce plant cover, which in turn enhances soil erosion. However, No-Tillage with weed cover should be researched to promote organic farming and sustainable agriculture. Therefore, we compare Tillage against No-Tillage using weed cover as an alternative …
Aportaciones al conocimiento de los mosquitos (Diptera, Culicidae) de alta montaña presentes en la Península Ibérica
2009
Several larval samplings of mosquitoes (Diptera, Culicidae) in different mountainous regions of the peninsular Spain were carried out. A total of 2796 specimens belonging to 18 species were collected, nevertheless the 72.5 % of these finds includes only three of them (Cx. hortensis hortensis, Cx. pipiens and Cs. longiareolata). The adaptation capacity to a varied typology of water bodies together with the marked multivoltinism that characterizes their biotic cycles are postulated as two of the principal reasons that explain their abundances. The altitudinal distribution as well as some information about the bioecology of all the species captured are also exposed.
Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean
2022
The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…
Regional metacommunities in two coastal systems: spatial structure and drivers of plant assemblages
2014
Aim Biogeographical patterns in metacommunities are still poorly understood, and different processes are expected to occur in different habitats. We analysed the regional plant metacommunities of coastal habitats to test whether (1) the influence of space and climate differs between two habitats differentiated along the seashore–inland gradient, and (2) regional variation in species composition of these habitats can be ascribed to different metacommunity paradigms. Location The entire coast of the Iberian Peninsula, south-western Europe. Methods We collected data on the plant species composition of coastal sites on sand dunes across 3000 km of coastline. The sites were classified into two h…
