Abstract The endosperm is a reproductive tissue supporting embryo development. In most flowering plants, the initial divisions of nuclei are not succeeded by cellularization; this process occurs only after specific number mitotic cycles have taken place. timing cellularization significantly influences seed viability and size. Previous research implicated auxin as key factor in initiating nuclear determining cellularization. Here we uncover involvement family clustered response factors...
During the Late Pleistocene, main mountain ranges of Iberian Peninsula were covered by small icefields and cirque alpine glaciers. The deglaciation triggered paraglacial processes that generated landforms, mostly within ice-free glacial cirques. In this research we analyse process in Muxivén Cirque (42°15′N – 6°16′W), upper Sil River Basin, which includes some largest relict rock glaciers Cantabrian Mountains. We addressed objective means accurate geomorphological reconstructions,...
A Schmidt hammer was applied for relative-age dating to 48 sites in 5 different massifs of the Cantabrian Mountains (NW Spain). The sample included glacial (moraines, erratics, and polished bedrock) periglacial (rock glaciers, blockfields, talus slopes) from last glaciation present geomorphological contexts. rebound (R) values agree with morphostratigraphic reconstructions, showing progressively lower older deposits. Six stages Last Glacial Maximum are inferred. results differ according...
The location of 173 complex, lobate and tongue-shaped relict rock glaciers in the Cantabrian Mountains are presented. Six zones were established based on morphostructural characteristics and/or glacier concentration. We analyzed importance lithology, slope aspect, with original relief conditions outcrops (fracturation network), distribution development these periglacial landforms.
A total of 156 glacial cirques located on two different areas in the Cantabrian Mountains (NW Spain) were identified and measured order to continue expand study these large‐scale erosional forms European mountains. Environmental variables that may explain cirque distribution (altitude, aspect lithology), their most important morphometric features (area, length (L), width (W), headwall height (H), L/W, L/H W/H indices), are analysed. Statistical analysis has been applied as indicators...
Air and near-surface ground temperatures were measured using dataloggers over 14 years (2006–2020) in 10 locations at 2262 to 2471 m.a.s.l. a glacial cirque of the Cantabrian Mountains. These sites exhibit relevant differences terms substrate, solar radiation, orientation, geomorphology. Basal temperature snow (BTS) measurements electrical resistivity tomography talus slope also performed. The mean annual ranged from 5.1 °C on sunny 0.2 rock glacier furrow, while air was 2.5 °C. Snow cover...
Fabric and grain-size analysis of eight deposits present in the Upper Sil River Basin palaeoglacial system northwest Spain were used to interpret till types reconstruct glacial paleoprocess history this region. They are represented by lodgement, deformation, melt-out tills. The first, representative advance stages, cluster fabrics generally composed poorly sorted finer sediments. Melt-out deformation tills, stages stability followed fast recession, transitional girdle coarser In any case,...
Ground temperature data obtained from 2002 to 2007 in sites near relict rock glaciers the cantabrian mountains, at altitudes between 1500 and 2300 meters is analysed. Snow cover lasted 3 9 months had a strong influence on thermal regime. When snow was present, soil normally frozen first 5 10 cm, but daily freeze-thaw cycles were rare. In well developed soils located sunny faces frost penetration rarely reached more than cm. contrary shady windy with scarce cover, reached, least, 40...
Abstract Mining activity introduces severe changes in landscapes and, subsequently, land uses. One of the most singular is existence pit lakes, which occur active more frequently, abandoned mines. Pit lakes are produced by water table interception when open-pit mines deepen. Their characteristics highly variable, depending on type mine, environment or climate. In León province there a long tradition coal mining that dates back to nineteenth century, and hundreds open pits from 1970s 2018...
For the first time in a sector of Cantabrian Mountains, Alto Sil, detailed avalanche hazard cartography has been carried out. This is based field observations, inquiries to local people and use Geographic Information System. In approach we define areas with suitable slopes, orientations, altitudes vegetation cover for avalanches. So, present maps recent avalanches areas, high risk low areas. Finally, two are showed like example zones where more relevant, Valseco Villarino del Sil
Snowfall in elevated areas of the mid-latitudes has a strong impact on infrastructure, freshwater availability, and climate system. The Cantabrian Mountains northwestern Iberian Peninsula are very vulnerable to change because their moderate altitudes, which limits snowfall. Monitoring snow events is essential for evaluation weather prediction models. However, measurement networks scarce mountainous have great uncertainties blizzards. In this study, multiphysics ensemble Weather Research...
The combined usage of till-fabric and grain-size analysis in the sedimentological interpretation glacial diamictons allows reconstruction processes responsible for genesis certain moraines. Till-fabric data from several late Quaternary moraines present three valleys Serra da Peneda Mountains northwestern Portugal revealed presence two types till deposited during stages. During first stage, ice advanced into lower Alto Vez Branda Junqueira lodgment tills moraine 1 (unit 1) moraine; therefore,...
From 2003 to 2009 it has been tracked snowpatches in Alto Sil, the Cantabrian Mountains. This work allowed us locate 8 nivation hollows this area. Currently 6 of them could be considered as active and 2 inactive. A more detail study around Joyas del Nevadín Valdeiglesia hollows, check snow erosion activity. It was observed an strong relation between quantity dinamic hollow. The sliding provokes nival striae clast displacements. Besides, rock outcrops is intense In these locations, also...
The article presents the 1:25,000-scale geomorphological map of upper reaches Curueño River, on southern slope Central Cantabrian Mountains, NW Spain. study area spans approximately 125 km2 and corresponds to Spanish National Topographical Map Sheet 104-I Lugueros. is moderately mountainous with elevation ranging from 1100 2100 m.a.s.l. main landforms are river gorges, karst, glacial landforms. legend contains 78 elements divided into 9 groups: litho-structural, polygenic, fluvial, glacial,...
