Datos sobre "Lathraea squamaria" en la provincia de León (España)

Abstract

Se estudian dos poblaciones de Lathraea squamaria L., especie parásita poco frecuente, en la ribera media-alta del río Esla (Crémenes, León, España), que resultan ser novedad para la provincia de León (España). Se describe la estructura de las poblaciones, se realiza un conteo del número de ejemplares, se hace un seguimiento de su fenología y se detalla su ecología mediante el levantamiento de inventarios fitosociológicos.

The introduction and spread of rye (Secale cereale) in the Iberian Peninsula

“…Moreover, the native distribution of mountain rye ( Secale montanum ) includes the Mediterranean basin, being mainly found in mountains of Central and Southern Iberia as well as in the Eastern Pyrenees, although it is currently rare (e.g. [ 4 , 5 , 111 – 117 ]). The record of one macroremain (grain) of mountain rye at Cova de les Cendres (Alicante, Eastern Iberia) indicates the presence of this species in the Late Gravettian [ 118 ].…”

Conservation status and protection measures forDraba hispanicaBoiss. subsp.lebruniiP. Monts., endemic to the Altocarrionés subsector (Castile and Leon, Spain)

“…In order to re-evaluate the state of the population of the taxon in accordance with IUCN criteria, an exhaustive literature review was first completed, including consultation of the Database of Vascular Flora of Castille andLeon (various authors, 2007-2008), the Information System on Spanish Plants (Anthos, http://www.anthos.es) and the National Node for Biodiversity Information (GBIF-Es, http://www.gbif.es). In addition, a considerable amount of fieldwork was carried out during the course of several projects and agreements with the Regional Government of Castilla y León for the production of detailed vegetation maps covering the "Fuentes Carrionas y Fuente Cobre-Montaña Palentina" Natural Park (Junta de Castilla y León, 2002León, -2007, and data was also obtained during the production of a preliminary Ph.D. project by one of the members of the research team and other studies relating to this (García González, 1990;García González et al, 1992;Rivas-Martínez et al, 1991).…”

“…is a narrow endemic plant to be found in the northern mountains of the Palencia Province in the Castile and Leon Region of Spain (Fig. 1), specifically in the Peña Cueto, Pico Fraile, Peña Redonda and Alto de Miranda zones (Blanca, 1993;García González, 1990;García González et al, 1992;Laínz, 1988;Montserrat, 1977;Rivas-Martínez et al, 1991;various authors, 2007-2008, over an area of seven and a half square kilometres (7.5 km 2 ). In terms of biogeography it is included in the Altocarrionés subsector of the Altocampurriano-Carrionés sector within Orocantabric subprovince of the Eurosiberian region, according to the innovative proposal put forward by Rivas-Martínez in 2007.…”

“…The grasslands in question are basophilic and chionophilic. They are situated on deep soils of the orotemperate stage of the hyperhumid ombroclime in contact with the serial grasslands arising from the degradation of scrub of Daphno cantabricae-Arctostaphyletum uvae-ursi Rivas-Martínez, Izco & Costa 1971(García González et al, 1992. Both vegetation types are included under code 6170 (Alpine and subalpine calcareus grasslands) in Annexe I of the Habitats Directive (Anonymous, 2007b) and, with codes 52.b.09.002 and 45.a.03.001 respectively, in the classification drawn up by Rivas-Martínez et al (1994), for Spanish vegetation of the habitat types of this Habitats Directive.…”

Los usos del agua en la Cuenca Leonesa del Sil (sistema Sil Superior)

“…En el primer caso, el modo de explotación era directo o se recurría al arriendo o subarriendo; cuando los molinos eran participativos, que es la fórmula más común en los pueblos de la cuenca, los derechos de molienda se reducían a determinados días o a unas horas según el número de interesados (éstos se adquirían por derecho, compra o herencia). El ordenamiento para su uso tiene su antecedente en el antiguo sistema de los vices o turnos practicado desde el siglo X, constituyendo con el tiempo parte fundamental del derecho consuetudinario (ALONSO GONZÁLEZ, 1993) Como dato curioso, sabemos que en el s. XVII se prohibió el cultivo de pimientos en el Bierzo y las razones que se daban eran, según Diego de Balboa, la reciente costumbre de moler pimientos en los molinos donde se muele el pan:…”
