In order to evaluate latitudinal differences in the relationship of phytoplankton biomass and diversity with environmental conditions shallow lakes, we sampled 98 lakes from three European regions: Denmark (DK), Belgium/The Netherlands (BNL) southern Spain (SP). Phytoplankton increased total phosphorus (TP) concentrations decreased submerged macrophyte cover across regions. Generic richness was significantly negatively related variables. Zooplankton:phytoplankton ratios were positively...
We analyzed the changes in epilimnetic total nitrogen (TN), phosphorus (TP), dissolved inorganic (DIN), and soluble reactive (SRP) 31 small high-mountain lakes Sierra Nevada (Spain) during an annual cycle, just after spring thaw, middle of growing season. Chlorophyll a, TN, TP increased, whereas TN:TP ratio fell substantially between two periods, reaching values generally 25 10 (by weight). On contrary, DIN, SRP, DIN:SRP ratios were similar for both periods each lake. ranged from 5 to 20...
In this paper we describe the main features of size-abundance distribution and taxonomic structure plankton in an oligotrophic, high mountain lake (La Caldera, Sierra Nevada, Spain). The is characterized by a discontinuity size range between ˜2000 32 000 μm 3 (cell volume). Phytoplankton are numerically dominated cyanobacteria Cyanarcus sp., followed chrysophyte Chromulina nevadensis diatom Cyclotella ocellata . Some microplanktonic species such as Navicula radiosa were observed...

The effect of increased UV radiation on photosynthesis estimated as in vivo chlorophyll fluorescence i.e. optimal quantum yield (Fv/Fm) and electron transport rate (ETR) the green filamentous alga Zygnemopsis decussata (Streptophyta, Zygnematales) growing high mountain lake "La Caldera" (Sierra Nevada, Spain) at 3050 m altitude was evaluated. Two sets situ experiments were conducted: (1) On July 2006, Fv/Fm measured throughout day different depths (0.1, 0.25, 0.5 1 m) afternoon, ETR phenolic...
We examined the response of plankton community to strong changes in volume oligotrophic Lake La Caldera through ice-free period 1995-1997. As consequence precipitation regime, lake diminished 2 m depth during extremely dry year 1995. The increase phosphorus availability for this caused diversification planktonic community, and autotrophic:heterotrophic (A/H) ratio was below 1. In spite sporadic dust loads associated atmospheric events, quick recovery volumen 1996 led a severe limitation....
The epilithic diatom assemblages studied in the high mountain lake “La Caldera” (Granada, Spain) from 1996 to 1998 went through two clearly different stages. initial one, 1996, corresponded reflooding of basin after a severe drought and was composed mainly colonising species Fragilaria rumpens, together with lesser presence Nitzschia sublinearis Hantzschia amphioxys. predominant F. rumpens at end summer 2006 coincided low diversity (values Shannon Wiener Index: 0.3-0.6). During following...
Abstract Autotrophic picoplankton (APP) is responsible for the vast majority of primary production in oligotrophic marine areas, such as Alboran Sea. The increase atmospheric dust deposition (e.g., from Sahara Desert) associated with global warming, together high UV radiation (UVR) on these ecosystems, may generate effects APP hitherto unknown. We performed an observational study across Sea to establish which factors control abundance and distribution APP, we made a microcosm experiment two...
Abstract The objective of this study was to explore the environmental factors having greatest influence on distribution and abundance epipelic diatom species in different wetlands southern Spain. We previously defined four groups conductivity categories: fresh (< 0.8 mS cm −1 ), oligosaline 8 mesosaline (8–30 ) eusaline (> 30 ). A dbRDA analysis performed a subset 36 53 wetlands, using total 25 variables, showed that five variables (conductivity, pH, wetland area, silicates, suspended...
Biological soil crusts (biocrusts) are a key component of dryland ecosystems worldwide. However, large extensions biocrusts disturbed by human activities, gypsum quarry being an outstanding example. Restoration techniques applied have offered satisfactory results for vascular plants but they could greatly differ in promoting biocrust recovery. A basic question remains unaddressed: can measures plant recovery accelerate or promote the biological crusts? We examined eight different situations:...
ABSTRACT Growth and sexual reproduction in a population of Cyclotella ocellata Pantocseck were studied during one annual cycle reservoir short‐term enclosure experiments performed situ involving different nutrient conditions concentrations zooplankton species. Three phases auxosporulation this diatom distinguishable morphologically: 1) preauxospore, from the beginning zygote formation until valves longitudinally separated, 2) primary auxospore, when grew too large to fit inside before it...

Cyanobacteria, green algae and diatoms are significant factors in the biodeterioration of stone cultural heritage sites, specifically fountain monuments, due to constant presence water. In this study, samples were taken from different fountains Alhambra Generalife, which among Spanish monuments greatest historical artistic value together declared a World Heritage Site by UNESCO 1984. The aim was identify species colonising microalgae most frequent obtain monoalgal cultures them. From...
