“…Because cyanobacteria contain taxa that demonstrably occupy distinct ecological niches (Loza et al ., ), they stand out among microbes as potentially optimal ecological indicators. In fact, they can be used effectively as such in studies of water quality in rivers (Schaumburg et al ., ; Mateo et al ., ). In dryland crusts, previous studies have shown that species distribution is very responsive to temperature (Garcia‐Pichel et al ., ), a fact that we could confirm and expand within our survey.…”

Cyanobacteria are a key biotic component as primary producers in biocrusts, topsoil communities that have important roles in the functioning of drylands. Yet, major knowledge gaps exist regarding the composition of biocrust cyanobacterial diversity and distribution in Mediterranean ecosystems. We describe cyanobacterial diversity in Mediterranean semiarid soil crusts along an aridity gradient by using next-generation sequencing and bioinformatics analyses, and detect clear shifts along it in cyanobacterial dominance. Statistical analyses show that temperature and precipitation were major parameters determining cyanobacterial composition, suggesting the presence of differentiated climatic niches for distinct cyanobacteria. The responses to temperature of a set of cultivated, pedigreed strains representative of the field populations lend direct support to that contention, with psychrotolerant vs thermotolerant physiology being strain dependent, and consistent with their dominance along the natural gradient. Our results suggest a possible replacement, as global warming proceeds, of cool-adapted by warm-adapted nitrogen-fixing cyanobacteria (such as Scytonema) and a switch in the dominance of Microcoleus vaginatus by thermotolerant, novel phylotypes of bundle-forming cyanobacteria. These differential sensitivities of cyanobacteria to rising temperatures and decreasing precipitation, their ubiquity, and their low generation time point to their potential as bioindicators of global change.

“…Focusing on these issues, Sukenik et al (2015) summarizes what we know of invasive cyanobacteria, cyanotoxins, and their ecological interactions. Cyanobacteria show varied morphological and physiological features under different ecologies and environments, and Mateo et al (2015) discuss their role as environmental indicators and bioreporters in aquatic ecosystems. Further Carmela Caroppo (2015) describes how the ecology and biodiversity of planktonic picocyanobacteria of coastal and brackish environments has potential applications in ecosystem sustainability.…”

“…The abundance of cyanobacteria is attributed to the favorable content of oxidizable organic matter and the lower levels of dissolved oxygen (Table 1), a similar observation was supported by Rao [72] and Venkateswarlu [73]. Phosphorus concentrations have been considered the main drivers of cyanobacterial growth [68,[74][75][76]. Boominathan [61] and Vijayakumar et al [62] suggested that environments rich in calcium cyanobacteria can grow prolifically.…”

“…The concentration and quality of nutrients are probably the more important factors which affect the cyanobacterial diversity [68]. The availability of phosphates and nitrates are important factors that favour the abundance of cyanobacteria in wetlands [59] and our sample with a high abundance and diversity of cyanobacteria is included in group 1 and had the highest concentration of P. The highest concentration of N appears to be related with the abundance of cyanobacteria from the Oscillatoriales order (filamentous without heterocyst).…”

Primary Producers and Anthropic Signs Related to the Flood Plain Soils of the Tablas de Daimiel Wetland

Abstract:In the Tablas de Daimiel National Park (TDNP) wetlands, a semi-arid wetland system in Spain that is of international importance, it is believed that pollutants from a variety of sources accumulate. In the study reported here, we evaluated soils from the flooded part of this wetland in an effort to establish relationships between the abundance/structure of microbial communities (mainly cyanobacteria) and certain soil properties (redox potential, dissolved oxygen, organic matter, soil reaction, electrical conductivity, calcium carbonate, total nitrogen, soluble phosphorus and total phosphorus). This objective was achieved by establishing one transect from the entrance to exit of the flood plain, including sampling from potentially polluted sites. Substantial variations between sampling sites were found in soil in terms of salinity, dissolved oxygen (DO), organic matter (OM), total phosphorus (TP) and nitrogen (TN). The presence of primary producers was more evident in contaminated samples. In addition to calcium, high levels of oxidizable organic matter, traces of dissolved oxygen, and considerable amounts of nitrate and phosphates probably stimulated the growth of cyanobacteria, these latter characteristics can be explained as being due to the influence of wastewaters from urban, industrial and agricultural activities that run off directly into this unique wetland. In the future it will be necessary to understand the synergic effects of other soil properties.
