Article
Mountain lakes are particularly sensitive to global change as their oligotrophic conditions may be rapidly altered after reaching an ecological threshold, due to increasing human impact and climate change. Sanabria Lake, the largest mountain lake in the Iberian Peninsula and with a recent history of increased human impact in its watershed, provides...

by fluctuations in the seasonal precipitation and wind, and the primary ACMs associated with the winter limnological processes are the NAO and the SCAND modes, whereas only the EA mode appears to weakly influence processes during the summer. However, Lake Las Madres is affected by precipitation, wind and, to a lesser extent, temperature, whereas th...
Article
Lakes are one of the best continental sensors for reconstructing past environmental and climatic changes. Recent lacustrine systems may be used for reconstructing with high-temporal resolution past climate parameters (e.g. precipitation, temperature, wind), land management changes and limnological conditions such as pH, salinity, or nutrients conce...

Monthly limnological monitoring in Lake Sanabria (Spain) since 1986 provided a unique opportunity to test relationships among climate, hydrology and lake dynamics and how they are recorded in the lake sediments. Four datasets were employed: (1) meteorological (monthly maximum and minimum air temperature and total precipitation), (2) limnological (S...
Article
It is well-known that lacustrine sediment records constitute one of the best environmental sensors to reconstruct climate variability. Nevertheless, our knowledge of how the climate signal (precipitation, temperature, wind stress) is transferred from the atmosphere to the lake water masses (through the limnological variables such as pH, nutrient in...

A new bathymetric map of Lake Sanabria is presented, showing depth isolines each meter and some morphometric parameters. The lake form, based on the relative hypsographic curve (cumulative area-depth), is concave (C). This lake shows high values of volume development (D v) and of the depth relation (mean depth/maximal depth ratio: z m/z max), which...

Se presenta un nuevo mapa batimétrico del lago de Sanabria, con curvas de nivel situadas a cada metro de profundidad y algunos parametros morfométricos. La forma de este lago, basándonos en la curva hipsográfica relativa del área frente a la profundidad es cóncava (C). Este lago tiene altos valores de los parámetros: desarrollo del volumen (Dy) Y l...

Chemical variables, algae, bryophytes, and vascular plants were determined in twelve mires located in the plateau of the Sierra Segundera range. All the mires studied are minetrophic in relation to water origin, and oligotrophic poor fens in relation to water chemistry. They were classified into two types: (a) `slope mires', developed in effluent b...

The aim of this work is to compare the composition and seasonality of the phytoplankton population in a natural oligotrophic lake (Lake Sanabria) and a mesotrophic reservoir (Valparaso). Both ecosystems are located on the Tera river course (NW Spain), which runs along an area of ancient metamorphic and plutonic rocks. Some physical and chemical par...

Abstract ALDASORO, J.J., C. AEDO, J. MUÑOZ, C. DE HOYOS, J.C. VEGA, A. NEGRO & G. MORENO. A sur- vey on Cantabrian mires (Spain). Anales Jard. Bot. Madrid 54:472-489. In thirty nine Cantabrian mires, several hydrological parameters were measured and charophy- tes, bryophytes and vascular plants were identified. Using principal coordinates of the ch...
