Lupinus mariae-josephii (Leguminosae) en la comarca de Camp de Turia (Valencia)

Se aporta para la comarca valenciana de Camp de Túria una nueva población de Lupinus mariae-josephae (Leguminosae), especie endémica de la Comunidad Valenciana (España), catalogada como Vulnerable en el Catálogo Valenciano de Especies de Flora Amenazadas. La población se localiza en el término municipal de Riba-roja de Túria y representa hasta el momento la más septentrional de su área de distribución.A new population of Lupinus mariae-josephae (Leguminosae) from Camp de Túria region is provided. This species is an endemic plant of Valencian Community (Spain) and it is listed as Vulnerable in the Valencian Catalog of Threatened Plant Species. This population is located in Riba-roja de Túria and constitutes the most northern of this species

Notas sobre la flora alóctona valenciana de origen ornamental.

Muchos de los neófitos detectados en los últimos años, tanto en la flora española como en la valenciana, corresponden a táxones introducidos en nuestro país con fines ornamentales, consecuencia de la creciente utilización de plantas alóctonas en jardinería

The “Alluvial Mesovoid Shallow Substratum”, a new subterranean habitat

Received: April 5, 2013; Accepted: August 23, 2013; Published: October 4, 2013In this paper we describe a new type of subterranean habitat associated with dry watercourses in the Eastern Iberian Peninsula, the “Alluvial Mesovoid Shallow Substratum” (alluvial MSS). Historical observations and data from field sampling specially designed to study MSS fauna in the streambeds of temporary watercourses support the description of this new habitat. To conduct the sampling, 16 subterranean sampling devices were placed in a region of Eastern Spain. The traps were operated for 12 months and temperature and relative humidity data were recorded to characterise the habitat. A large number of species was captured, many of which belonged to the arthropod group, with marked hygrophilous, geophilic, lucifugous and mesothermal habits. In addition, there was also a substantial number of species showing markedly ripicolous traits. The results confirm that the network of spaces which forms in alluvial deposits of temporary watercourses merits the category of habitat, and here we propose the name of “alluvial MSS”. The “alluvial MSS” may be covered or not by a layer of soil, is extremely damp, provides a buffer against above ground temperatures and is aphotic. In addition, compared to other types of MSS, it is a very unstable habitat. It is possible that the “alluvial MSS” may be found in other areas of the world with strongly seasonal climatic regimes, and could play an important role as a biogeographic corridor and as a refuge from climatic changes.The Spanish Ministry of Science and Innovation for funded this research project (CGL2010-19924) and the Ministry of Education and Science programme "Juan de la Cierva".
