Resumen: Se describe una nueva asociación vegetal, Saturejo valentinae-Teucrietum buxifolii (All. Teucrion buxifolii), dominada por Teucrium buxifolium subsp. buxifolium, propia de las sierras litorales e interiores del sector Setabense. Es una comunidad de bajo recubrimiento que crece en grietas de roquedos calizos de las áreas termo-mesomediterráneas. Se aportan asimismo datos sobre la composición florística, comportamiento ecológico y distribución.; A new plant association, Saturejo valentinae-Teucrietum buxifolii (All. Teucrion buxifolii), is described from the coastal and inland mountains in the Saetabensian sector, which is dominated by Teucrium buxifolium subsp. buxifolium. This is a low-coverage plant community occurring in rock crevices of limestone cliffs of the thermo-mesomediterranean areas. Data on the floristic composition, ecology and distribution are also reported.2024-02-01T00:00:00ZSideritis royoi (Lamiaceae): A New Orophilous Species from Northeastern Spain

Título: Sideritis royoi (Lamiaceae): A New Orophilous Species from Northeastern Spain
Autor/es: Sáez, Llorenç; Curto, Rafel; Crespo, Manuel B.
Resumen: Sideritis royoi is found in the rocky limestone habitats of the Port Massif (southern Catalonia, Spain). The species was first collected by the local botanist Lluís de Torres in the late part of the 20th century, but the specimens have remained unidentified positively in herbaria for over 40 years. Sideritis royoi likely belongs to section Sideritis subsection Hyssopifoliae and shows some morphological affinities with the relatively widespread South European species S. hyssopifolia L., but it differs from this species because it has subspinescent upper leaves, the main surfaces of its leaves are glabrous or glabrescent, the main abaxial surface of its bracts is without eglandular hairs, and due to the fact that it has shorter inflorescences. Weaker similarities have also been observed with some species belonging to S. subsection Fruticulosae Obón & D.Rivera. In this paper, a description for the new orophilous species is provided, along with a detailed illustration, field photographs, and a comparison with closely related species. We include an assessment of its conservation status and a dichotomous key for the identification of all the species of Sideritis subsection Hyssopifoliae.2024-01-18T00:00:00ZInteractions between rabbits and dung beetles influence the establishment of Erodium praecox

Resumen: We examine the potential for two species – the wild rabbit Oryctolagus cuniculus and the dung beetle Thorectes valencianus – to affect the establishment of Erodium praecox, an endemic plant of the Iberian Peninsula. Rabbit latrines may be considered potential maternal parent areas of E. praecox. The spatial and temporal stability for nutrients and surface irregularities caused by the activity of rabbits increases bare soil areas. A negative relation between diameter of the basal rosettes of Erodium and the distance to the centroid of latrines was observed. Rabbit latrines were important for E. praecox distribution but their effect was higher when T. valencianus burrows exist. In laboratory conditions, a higher number of seeds buried was observed in latrines with dung beetles, while a lower number of seeds buried was observed in bare soil. T. valencianus activity plays the role of a soil fertilizer, increasing the rate of nutrient cycling and microbial activity which could raise the rate of decomposition of pellets and result in the further release of nutrients. The excavation of the dung beetles increases the soil fertilization and the surface irregularities required for the seeds of E. praecox to be easily self-buried.2009-03-27T00:00:00ZTaxonomic revision of Ornithogalum subg.

Resumen: As part of a taxonomic revision of the Iberian and Balearic taxa of Ornithogalum, quantitative and qualitative characters are studied in detail in Ornithogalum subg. Beryllis (Salisb.) Baker, and they are evaluated for taxonomy of the two taxa: O. narbonense L. and O. pyrenaicum L. A complete description is presented for both species, and data on their biology, ecology, and distribution are also included. Moreover, a key is provided to facilitate identification.; En el marco de una revisión de las especies ibéricas y baleares de Ornithogalum, se estudia con detalle O. subg. Beryllis (Salisb.) Baker, y se evalúa cualitativa y cuantitativamente el valor taxonómico de los caracteres morfológicos de los dos táxones: O. narbonense L. y O. pyrenaicum L. Para cada especie se presenta una descripción completa y datos sobre su biología, ecología y distribución. Además, se aporta una clave para facilitar la identificación de los táxones aceptados.2009-01-01T00:00:00Z
