AbstractWe report the occurrence of facultative paedomorphosis in the three species of newts (Pleurodeles waltl, Lissotriton boscai and Triturus pygmaeus) from dry and seasonal Mediterranean areas from southern Spain. These are the first records of paedomorphosis for P. waltl and L. boscai, and the second for T. pygmaeus. Other than the previous T. pygmaeus record, these are the first observations of paedomorphosis in the southern half of the Iberian Peninsula. Most of specimens demonstrating paedomorphosis live in artificially permanent aquatic environments. Nevertheless, a paedomorphic individual of L. boscai was found in a natural yearly temporary brook that held water during the previous two years. Paedomorphs are at low frequency in most cases. However, a single isolated population of P. waltl is probably composed entirely of paedomorphs.

Original Concept

Metahadzia uncispina n. sp. is described, being the second species of the genus on the Iberian Peninsula. The new species, well characterized by the transformation of the apical spine on the endopodite of the male uropod 2, is undoubtedly closely related with M. tavaresi (Mateus & Mateus, 1972) from the south of Portugal. Comments are made about recent emendations of the original concept of the genus Metahadzia Stock, 1977.

A detailed knowledge of soil water repellency (SWR) and water infiltration capacity of soils under different land uses is of fundamental importance in Mediterranean areas, since these areas are prone to soil degradation risks (e.g., erosion, runoff of polluting compounds) as a response to different hydrological processes. The present study evaluates the effects of land uses on SWR and soil hydraulic conductivity (SHC) by direct measurements at the plot scale in three areas representing (1) intensive agricultural use, (2) abandoned farmland, and (3) a forest ecosystem in Southern Spain under Mediterranean climatic conditions. The physico-chemical properties and water content of the experimental soils were also measured. Significant SWR and SHC differences were found among the analyzed land uses. Forest soils showed high SWR and low SHC, while the reverse effects (that is, low SWR and high SHC) were detected in soils subjected to intensive agriculture. Organic matter and bulk density were important soil properties influencing SWR and SHC. The study, demonstrating how land uses can have important effects on the hydrological characteristics of soils, give land managers insights into the choice of the most suitable land use planning strategies in view of facing the high runoff and erosion rates typical of the Mediterranean areas.

AbstractPlacobdella costata is a leech specific to freshwater turtle Emys orbicularis. Both genera are native to North America and have co-evolved and undergone dispersion through the Palearctic. The leech is present throughout the Mediterranean area, always associated with E. orbicularis. Their only known presence in the Iberian Peninsula is in the north and center of the peninsula. Here we present the first description of the leech in southern Spain (Andalusia) in association with a small fragmented population of fresh-water turtles in which E. orbicularis and Mauremys leprosa coexist. Unusually, the leech was found attached to the carapace of a male M. leprosa.

An intact archaeological context named Locus 1 has recently been discovered at Dehesilla Cave (southern Spain). The ritual funerary deposition consists of a complete pottery jar with part of a human calvarium over the mouth, and was occulted by large stone blocks. This paper offers a presentation of the new data provided mainly by the stratigraphic, osteological, pottery, lithic and radiocarbon analyses. A systematic review of the relevant evidence in the Iberian Peninsula during the Early Neolithic (c. 5600–4800 cal BC) provides a context for this finding and supports its interpretation with reference to several possible anthropological scenarios.

La biología térmica es uno de los aspectos más necesarios para entender la distribución y los patrones de actividad de las especies, sobretodo de los organismos ectotermos. El presente estudio aporta información sobre temperatura corporal de seis ofidios ibéricos y temperatura ambiental para el lugar donde habitan. Para tres de las especies, Coronella girondica (Daudin 1803), Macroprotodon brevis (Günter 1862) y Hemorrhois hip­pocrepis (Linnaeus 1758), estos son los primeros datos publicados en España. En el caso de Natrix maura (Linnaeus 1758) los datos de este estudio incluyen temperatura tanto en medio acuático como en medio terrestre. En total se han obtenido 31 registros de temperatura corporal y 30 registros de temperatura ambiente. También se aportan datos sobre temperatura corporal y ambiental de Malpolon monspessulanus (Hermann 1804) y Zamenis scalaris (Schinz 1822). Thermal biology is one of the most necessary aspects in understanding the distribution and activity patterns of species, above all of ectothermal organisms. The present study provides data on body temperature of six Iberian ophidians and the environmental temperature of the place they inhabit. For three species, southern smooth snake Coronella girondica (Daudin 1803), western false smooth snake Macroprotodon brevis (Günter 1862), and horse-shoe snake Hemorrhois hippocrepis (Linnaeus 1758), these are the first data published in Spain. In the case of Natrix maura (Linnaeus 1758), the present data include its temperature on land as well as in aquatic environments. In total, 31 body temperature records and 30 ambient temperature records were obtained. Additionally, data is given on body and environmental temperature for the ophidian species Malpolon monspessulanus (Hermann 1804) and Zamenis scalaris (Schinz 1822).

AbstractBasidiolichens are generally poorly researched because of the very small number of species and their restriction to special niches. Lichenomphalia basidiolichens grow in considerable quantities in arctic and alpine habitats but they are inadequately studied in these habitats in Mediterranean areas. Based on morphological and phylogenetic analyses, we identified the different symbionts of L. meridionalis, collected in localities in Spain at altitudes ranging from 533 to 2200 m above sea level. The present study provides the first molecular data available for L. meridionalis. We found that a microindel of six bp within the nrITS2 could help to discriminate L. meridionalis from other species of the genus. Molecular analyses revealed the existence of two different green algal strains, both belonging to Coccomyxa subellipsoidea, a species shared with other Lichenomphalia lichens. Notably, the two chlorobiont strains associated with L. meridionalis were differentially distributed according to altitude, and samples having one of the two strains consistently also included cyanobacteria.

AbstractSlushflows were first recorded in the Iberian Peninsula on 18 December 1997. Three slushflows were released at the ski resort of El Port del Comte, in the Catalan Pyrenees, northeast Spain, during intense rainfall. Two of the slushflows originated on the pistes, and the third affected another piste. Three ski lifts were damaged. This paper analyzes the hydrogeological characteristics of the massif, the geomorphic features of the terrain and the meteorological and snowpack conditions that caused the release of the slushflows. Man's role in triggering the slushflows by compacting snow on the pistes is also considered. Drainage control for reducing the hazard is outlined, taking into consideration the low frequency of the phenomenon.

The Ribbed newts (genus Pleurodeles) are endemic to the Iberian Peninsula and northwest Africa (Raffaëlli 2013), and comprise three species: Pleurodeles nebulosus (Guichenot 1850), Pleurodeles poireti (Gervais 1836) and Pleurodeles waltl Michahelles 1830. Pleurodeles nebulosus is found in northern Algeria and Tunisia with an average size of 18 cm, while P. poireti is endemic to the Edough Massif, in northeastern Algeria and is the smallest species, with 12.9 cm in total length (Escoriza et al. 2016; Carranza & Wade 2004). Pleurodeles waltl appears on the Iberian Peninsula and Morocco (García-París et al. 2004). The eastern and western populations of P. waltl although they are not differentiated taxonomically show high levels of genetic divergence (estimated to have occurred 2.0–3.2 Ma; Carranza & Arnold 2003). The individuals of P. waltl attain large sizes (30 cm of total length) and have 8−10 cutaneous glands on both sides (Pasteur 1958), which are absent in other species of the genus.
