Opis:: Ceratosaurian theropods evolved in two bursts, first in the Middle and Late Jurassic and then in the Late Cretaceous, leaving a 20 Myr gap in the Early Cretaceous during which remains are rare. We describe here a new ceratosaurian theropod, Camarillasaurus cirugedae, from fluvial deposits of the Camarillas Formation (lower Barremian, Lower Cretaceous) of Camarillas, Teruel Province, NE Spain. The new theropod is represented by a collection of associated bones, including a tooth, a possible cervical vertebra, two sternal plates, the proximal part of a right tibia, a broken right scapulocoracoid, the incomplete sacrum, five caudal vertebrae, an isolated caudal neural arch, a chevron, an almost complete presacral rib and some fragments of vertebrae, ribs, and other elements. Camarillasaurus is differentiated from other theropods by the extreme depth of the tibia proximal end, and a deep longitudinal groove on the tibia. The new dinosaur is a ceratosaur, phylogenetically close to the base of the clade, and perhaps more derived than the Chinese basal ceratosaur Limusaurus. The new taxon is significant in the evolution of the ceratosaurian dinosaurs, being placed temporally between its more common Jurassic and mid-Upper Cretaceous relatives, and it is one of only a few from Laurasia.

Opis:: Although aerobiological data are frequently used as a fl owering sign in phenological research, airborne pollen counts are infl uenced by a number of factors affecting pollen curves. A study was made about the reproductive biology of birch and environmental factors infl uencing its pollen release and transport, in order to achieve a reliable interpretation of Betula pollen curves. Aerobiological data were recorded in 2002 and 2003 at two sites in NW Spain and phenological observations were carried out on 20 trees from four Betula populations (three Betula alba L. and one B. pendula Roth.). Pollen production was calculated for six Betula alba trees. Chilling and heat requirements for triggering development were calculated. Due to differences in the geographical location, budbreak and fl owering started fi rst in Betula pendula. The fl owering period lasted from 8-13 days. Reduced pollen output per anther and catkin in individual trees in 2003 prompted a marked decline in overall pollen production. Major differences observed in birch pollen curves were attributed to the infl uence both of weather conditions and pollen transport from areas where the fl owering occurs at a different time. Heat requirements calculated using phenological and aerobiological data were similar when the peak pollen- count date was used.

Opis:: We describe the most complete and best−preserved materials assigned to Simocyon from Spain. Specimens come from the late Miocene (Vallesian) locality of Batallones−1, Province of Madrid and are assigned to Simocyon batalleri. Cranial, mandibular and dental anatomy of S. batalleri from Batallones−1 is described and compared with those of known species of Simocyon. We review the systematic status and the definition of the species of Simocyon and we analyse the morphological variation within Simocyon. Three species are recognized as valid. S. batalleri is known from several Vallesian localities (mainly MN 10) of Spain. S. diaphorus, from the early Vallesian of Germany (Mammal Zone MN 9), is the geologically oldest European species. The type species S. primigenius is Turolian in age and known from several localities of Europe, North America, and China. The species includes the junior synonyms S. zdanskyi and S. marshi. The status of Simocyon hungaricus is not resolved. Simocyon simpsoni is excluded here from Simocyon and reassigned to its original generic name Protursus. On the basis of the material described here, we propose a differential diagnosis for Simocyon batalleri. This species is morphologically intermediate between the more primitive S. diaphorus, which has a less reduced p3; and the more derived S. primigenius, characterized by a modified mandible (e.g., more vertical and more expanded coronoid process, longer angular process). The evolution of the genus Simocyon is characterized by a trend toward a more crushing adaptation involving at least a modification of the posterior part of the mandible. A reconstruction of the skull and life appearance of Simocyon is proposed.

Opis:: Astragalus nitidiflorus is an endangered legume endemic to the southeast of the Iberian Peninsula. This species develops symbiotic relationships with N-fixing bacteria. However, the problem of isolating its rhizobia has not been solved. Because poor N fixation in plants can be corrected by fertilization, the effect of N-P-K fertilizers on growth, leaf chlorophyll and mineral ions was studied. Plants of A. nitidiflorus were grown in 100%-substrate with different N-P-K fertilizer rates (mg l–1): 1-1-8 (S0), 69-29-35 (SL), 144-43-131 (SM) and 245-58-235 (SH). A treatment with substrate plus soil from the natural habitat and no fertilizers (T0) was included. The reference foliar contents of N, P and K were 42.5, 3.5 and 36.5 mg g–1, respectively. Although the species did not form root nodules when grown in substrate, T0 plants produced active nodules that allowed the plants to grow properly without fertilization. In the absence of nodules, both N fertilization (~144 mg l–1) and Fe fertilization (>12 mg l–1) are vital, as is, to a lesser extent, K fertilization (~75 mg l–1 K2O). The S0 and SL reduced leaf chlorophyll, while SM prevented its degradation.
