New records of vascular plants from Sierra del Rincón Biosphere Reserve and surroundings (Spain, Madrid province) are provided. It is noteworthy the presence of atlantic flora in this continental area and the different shrubby communities in different sectors with different litology: in areas with gneiss they are dominated by leguminous genisteae; where it is schistous, shale or quartzite they are heathlands.

Se realiza una propuesta de división en subsectores del sector Setabense (Provincia biogeográfica Catalano- Valenciano-Provenzal). Las unidades reconocidas son: 1 subsector Valenciano;2 subseetor Enguerina-Cofrentino; 3 subsector Ayorano-Villenense; 4 subsector Alcoyano-Diánico. Para cada uno de ellos se aporta una breve descripción y caracterización de su flora, vegetación, paisaje vegetal, suelos, bioclimatología, usos del territorio, etc. Además se proponen dos nuevas combinaciones taxonómicas: Asperula paui Font Quer subsp. dianensis (Font Quer) de la Torre, Alcaraz & Crespo y Linaria depauperata Leresehe ex Lange subsp. hegelmaieri (Lange) de la Torre, Alcaraz & Crespo, y se valida la combinación Arctostaphyllos uva-ursi (L.) Sprengel subsp. crassifol¡a (Br.-Bl.) Rivas-Martínez ex de la Torre, Alcaraz & Crespo.

Several vertebrae of a sauropterygian specimen have been recovered in Fuencaliente de Medinaceli (Soria Province, Castilla y León, Spain). The remains come from Middle–Upper Triassic Muschelkalk Facies. This finding represents the first documented evidence of a Triassic tetrapod in Castilla y León. The vertebrae belong to Nothosaurus, a sauropterygian genus found in Europe, Middle East, North of Africa and China. This genus is poorly-known in the Iberian record. The new remains constitute the first evidence of the species Nothosaurus giganteus, or a related taxon, in the Iberian Peninsula. This study reveals the occurrence of at least two species of the sauropterygian Nothosaurus in the Spanish record.

The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs. The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is also interpreted here as rapid. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual. The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valangian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms.

Las zonas de montaña cuentan con especificidades geográficas y socioeconómicas. En ellas, a partir del patrimonio territorial natural y cultural, se ha producido un considerable impulso del turismo rural, que ha centrado el interés en la valoración de la singularidad y variedad de los paisajes. En este caso se presta atención a las sierras meridionales de la provincia de Albacete. El trabajo se apoya en una metodología que combina el uso de encuestas de preferencias de turistas y técnicas cartográficas a partir de algunas variables del sistema turístico en el medio rural. El trabajo se inserta dentro de los paradigmas del desarrollo local y el desarrollo sostenible, aplicado a los espacios rurales y a las zonas de montaña media del sureste de Castilla-La Mancha. La hipótesis se centra en la consideración del paisaje como elemento medular del turismo rural.
