“…The phytoplankton abundance and biomass values in Cyprus' saline lakes were similar to those reported for other saline lakes (e.g., [23,63,76]). In the majority of the lakes, higher abundances were recorded in January or February, usually when water levels increased due to increased water inputs and a subsequent decrease in salinity.…”

“…In the majority of the lakes, higher abundances were recorded in January or February, usually when water levels increased due to increased water inputs and a subsequent decrease in salinity. The same relationship between total abundance and salinity has been described in other salt lakes, where total abundance and biomass decrease as salinity increases [63], since most phytoplankton species are eliminated at very high salinity levels due to osmotic stress [59]. Higher mean abundance values and higher variability were recorded at Lakes Oroklini and Larnaka Main.…”

“…Although the lakes are all temporary, shallow and saline, they had marked differences in the range of their abiotic parameters (period of inundation, water level and salinity), but nevertheless, did not exhibit marked differences among one another regarding species composition, as has been shown in other Mediterranean saline lakes (e.g., Spain) [63]. The nMDS results indicated overall high similarity (>40% similarity clustering) of most phytoplankton communities of salt lakes in Cyprus, independent of spatial and seasonal variability.…”

“…The analysis of alpha and beta diversity revealed low and highly variable biodiversity (Simpson's 1-D) both temporally and spatially (among lakes), revealing the dominance of one species (especially in the hypersaline Lake Larnaka Main) and coexistence of more than one species in the other lakes. Low Simpson's values in Lake Larnaka Main were expected since phytoplankton diversity is very low in systems with high salinity and an ephemeral regime [63]. Other indices also fluctuated in all cases (Shannon's H and Evenness), suggesting alternations in species distribution homogeneity patterns/dynamics, and the presence of skewed communities in terms of species abundance (i.e., lower Shannon and Evenness indices) in several cases.…”

The ephemeral saline lakes of Cyprus in the Mediterranean, situated in close proximity to each other, demonstrate pronounced seasonal and interannual fluctuations in their environmental conditions. Despite their extreme saline conditions, these lakes support phytoplankton diversity and bloom-forming species. Anthropogenic activities, particularly urban and artificial land uses within their catchments, contribute to eutrophication, warranting conservation attention within the context of European legislation. Over two years (2018–2019), we examined phytoplankton abundance and diversity alongside salinity in six lakes, with samples collected every three weeks. Chlorophytes were the dominant and most diverse group, followed by cyanobacteria and diatoms. Increasing salinity correlated with reduced compositional diversity and species richness. The proximity of lakes to each other suggested airborne microbe colonization from one lake to another as a significant factor in shaping these communities, while similar land use within each lake’s catchment impacted bloom formation. The highly halotolerant chlorophyte Dunaliella frequently dominated phytoplankton blooms, occasionally coexisting with other taxa in less saline lakes. Our findings provide insight into the phytoplankton community dynamics in temporal saline lakes, essential for developing effective conservation strategies and sustainable management practices.

Initial appraisal of water quality of Lake Santa Ana, Mexico

2009

Lake Santa Ana is located in the Mexican central plateau, a semiarid region characterized by low rainfall and high evaporation rates. Because of the area's climatic conditions, most of its few existing lakes and reservoirs are ephemeral, with significantly reduced surface areas during the dry season. Mexican authorities currently pay little or no attention to these special aquatic ecosystems. As a consequence, several of these waterbodies are severely degraded in regard to both water quantity and quality. As a result, this report describes Lake Santa Ana as a case study. Several water quality parameters, including physicochemical, microbiological and heavy metal concentrations, were measured at eight sampling sites in the lake, and four sites in the lake basin, in 2005. Some dissolved ions were also analysed in 2007 in the lake, and in a well located close to the lake, in order to evaluate possible interactions between groundwater and surface waters. These study results indicate that the lake does not have significant interactions with groundwater in the local aquifer. Most of the measured water quality parameters do not meet the international suggested standards for inland surface waters to sustain aquatic life, and preserve the habitat for both endemic and migratory waterfowl. Loss of aquatic habitats puts at risk the value of the central portion of Mexico as a migratory route for North American waterfowl species.

In inland aquatic ecosystems, drying and salinity can co-occur as natural stressors, affecting aquatic invertebrate communities. Despite recent appreciation of the importance of temporary waterbodies for terrestrial invertebrates, knowledge about the effects of drying on dynamics of aquatic and terrestrial invertebrate communities is scarce, especially in saline ecosystems. This study analyzed structural and compositional responses of both communities to the coupled effects of drying and salinity in two streams and two shallow lakes in Spain, during three hydrological phases: wet, contraction, and dry. In the two studied saline streams, the contraction phase presented the highest aquatic and terrestrial abundance and richness, and the main compositional changes were mainly due, to an increase in aquatic lentic taxa (e.g., Coleoptera), and Araneae and Formicidae as terrestrial taxa. In shallow lakes, which presented highly variable salinity conditions, the highest abundance and diversity values were found at the wet phase for aquatic invertebrates and at the dry phase for terrestrial invertebrates. Compositional invertebrate community changes were due to a decrease in Rotifera and Anostraca (aquatic taxa) in the contraction phase for aquatic communities, and to an increase of Araneae, Coleoptera, and Formicidae (terrestrial taxa) at the dry phase for the terrestrial. Our study evidences the significant effect of drying on both aquatic and terrestrial invertebrates communities in natural inland saline waters and the need to integrate aquatic and terrestrial perspectives to study temporary inland waters.
