sum tini Molero, Sáez and Villar-, altered by the presence of certain thermophilous coastal species, and finicolous and residual in character, are found in a few exceptional enclaves. Finally, stress is laid on the need to introduce suitable measures for the protection of certain places in the Range, particularly the residual woods of the northern slopes, in view of the exceptional interest of the flora and landscape. Key words: Flora, Vegetation, Chorology, Cormophytes, Sierra de Alcubierre, Monegros, Ebro valley, Spain.

Como resultado de una excursión realizada el 23 de Marzo de 1980 a la Sierra de Orihuela, macizo perteneciente a la provincia corológica murciano-alménense, sector murciano, se citan 87 táxones de los que la mayor parte (cerca de un 70%) corresponden a terófitos. De entre las citas cabe destacar como nuevas para la provincia de Alicante: Crassula tillaea Lester-Garl. y Eryngium ilicifolium Lam. Plantago ovata Forsk. y Notoceras bicorne (Aitón) Amo fª. hispanicum WK. no se habían vuelto a encontrar en la zona desde que Rouy y Lagasca respectivamente lo hicieran el siglo pasado.

The Triassic-Jurassic boundary is generally considered as one of the major extinctions in the history of Phanerozoic. The high-resolution ammonite correlations and carbon isotope marine record in the New York Canyon area allow to distinguish two negative carbon excursions across this boundary with different paleoenvironmental meanings. The Late Rhaetian negative excursion is related to the extinction and regressive phase. The Early Hettangian delta(13)C(org) negative excursion is associated with a major floristic turnover and major ammonite and radiolarian radiation. The end-Triassic extinction-Early Jurassic recovery is fully compatible with a volcanism-triggered crisis, probably related to the Central Atlantic Magmatic Province. The main environmental stress might have been generated by repeated release of SO(2) gas, heavy metals emissions, darkening, and subsequent cooling. This phase was followed by a major long-term CO(2) accumulation during the Early Hettangian with development of nutrient-rich marine waters favouring the recovery of productivity and deposition of black shales.
