First record of Synedropsis roundii (Bacillariophyta, Fragilariaceae) in the Mediterranean region
2019
Populations of the fragilarioid diatom Synedropsis roundii are described from the phytoplankton of the Albufera of Valencia, a large and shallow eutrophic lagoon in the Spanish Mediterranean coast. The specimens collected are described and illustrated with light and scanning electron microscopy. This is the first documented record of this species since its description, and the first illustrated record of the genus in the Mediterranean region. The Albufera lagoon and the type locality of the species (Imboassica Lagoon, SE Brazil) are similar in some ecological features. The ecological and biogeographical implications of this finding are briefly discussed.
Rainfall drop size distribution in the Western Mediterranean basin, València, Spain
1997
Although soil erosion processes are directly related to the raindrop sizes and the kinetic energy of the rainfall, little is known about the drop-size distribution. The paper staining technique is used to measure the size of the raindrops for natural thunderstorms with different rainfall intensities in the Western Mediterranean basin (Canals and Valencia, Spain). Drop sizes are greater during the most intense thunderstorms, ranging from 0.25 mm diameter (D50) for a 1 mm h−1 rainshower to 2.69 mm in very intense thunderstorms of about 120 mm h−1. The shape of the raindrop size distribution curve changes from lower to higher rainfall intensity thunderstorms. For the low intensity events, the …

Flora y vegetation briof�tica higro-hidr�fila de la comunidad Valenciana (Este de Espa�a)
1999
The bryophyte flora and vegetation have been studied in aquatic and wet environments of Valencia County (eastern Spain). A catalogue of 74 taxa is given, 3 species are new for eastern Spain and 6 for provinces of Valencia County (Valencia = 4, Castellon = 2). Aquatic communities have been studied according to the Braun-Blanquet (1952) method. Nine associations belonging to the classes Adiantetea, Montio-Cardaminetea and Platyhypnidio-Fontinalietea have been recognized. One association has been described as new, Fontinaletum hypnoidis ass. nova, which always grows submerged in calcareous, unpolluted and flowing water. Ecological and syntaxonomical data on problematical communities in the Med…
The Magdalenian harpoons from the Iberian Mediterranean, based on pieces from Cova de les Cendres (Teulada-Moraira, Valencian region)
2012
Abstract Harpoons are one of the most characteristic implements of the Upper Magdalenian. However, morphologic differences in barbs and bases mark different regional traditions. This paper gives an account of the main features of harpoons in the Iberian Mediterranean, based on findings from Cova de les Cendres, and compares them with those found in other areas in Western Europe. The specificities of Mediterranean harpoons (a single range of barbs, variable length and number of barbs, and lack of hafting devices on the base) are considered in discussion of their potential functions and possible hafting systems.
Sensitivity of precipitation forecasts to convective parameterization in the October 2007 Flash Flood in the Valencia Region (Eastern Spain)
2018
Abstract. The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is an area prone to torrential rains, especially the north of Alicante province and the south of Valencia province. In October 2007, a torrential rain event with accumulated rainfall values exceeding 400 mm in less than 24 h affected the aforementioned areas, producing flash floods that caused extensive economic losses and human casualties. Several simulations of this rain event have been performed with the Regional Atmospheric Modeling System (RAMS) to test the influence of the different convective parameterization scheme implemented in the model on the precipitation forecast.
Aspilota-group (Hymenoptera: Braconidae: Alysiinae) diversity in Mediterranean Natural Parks of Spain
2014
This work analyses the biodiversity of the Aspilota-group (Hymenoptera: Braconidae: Alysiinae) in three Mediterranean Natural parks: Natural Park of La Font Roja, Natural Park of Las Lagunas de la Mata-Torrevieja and Natural Park of La Tinença de Benifassà. Samples were carried out from April 2004 to December 2007. In total, 822 specimens, belonging to 52 species, were collected. Alpha, beta and gamma diversities were analysed, and the Tinença Park was proven to have higher diversity than the Font Roja and Torrevieja. Also, the structure of the Aspilota-group community was analysed.
Middle Palaeolithic flint procurement in Central Mediterranean Iberia: IMplications for human mobility.
2014
Different flint types from the Middle Palaeolithic site of Abrigo de la Quebrada (Chelva, Valencia) are characterized, both macro- and microscopically, and compared with types found at other localities in the region. Although procurement predominantly concerned the immediate vicinity of sites, our results show the presence of the same types in assemblages separated by distances of up to 120 km. The long distances involved are suggestive of a pattern of North-South mobility of human groups along the coastline of central Mediterranean Iberia.
Short and medium effects on the environment of Valencia, Spain, of the Chernobyl nuclear plant accident.
1991
As a consequence of the 26 April 1986 accident at the Chernobyl nuclear plant, a large amount of radioactivity was released into the atmosphere. The radioactive plume formed could be detected in practically the whole of the Northern Hemisphere a few days later. The zone most affected by the radioactive cloud over Spain was that of the Mediterranean coast and the Balearic Islands. In this paper, the authors examine the level of the radioactive contamination reached in various receptive media in Valencia, such as air, dry-fallout, water, soil, grass and milk samples collected in Valencia immediately after the accident. The activity levels are compared with those found during 1964 and 1965 due…
Middle Miocene foraminifera from Canals (Valencia, western Mediterranean). Biostratigraphic and palaeoenvironmental aspects
2020
The age and the palaeoenvironmental conditions of the tap marls outcroppings near the locality of Canals in the south of the Valencia Province (E Spain) are discussed. Based on the planktonic foraminifera assemblages, mainly the species Globorotalia praemenardii , these tap marls are dated as Serravallian in age (middle Miocene). The analysis of the foraminiferal assemblages suggests a relatively well-ventilated uppermiddle bathyal environment, with only a moderate oxygen deficiency throughout most of the studied section. The rather cool waters indicated by the planktonic foraminifera (e.g. Globigerina bulloides ) are compatible with the decreasing temperatures trend during the middle Mioce…
