Dominance by cyanobacteria hampers human use of lakes and reservoirs worldwide. Previous studies indicate that excessive nutrient loading and warmer conditions promote dominance by cyanobacteria, but evidence from global scale field data has so far been scarce. Our analysis, based on a study of 143 lakes along a latitudinal transect ranging from subarctic Europe to southern South America, shows that although warmer climates do not result in higher overall phytoplankton biomass, the percentage of the total phytoplankton biovolume attributable to cyanobacteria increases steeply with temperature. Our results also reveal that the percent cyanobacteria is greater in lakes with high rates of light absorption. This points to a positive feedback because restriction of light availability is often a consequence of high phytoplankton biovolume, which in turn may be driven by nutrient loading. Our results indicate a synergistic effect of nutrients and climate. The implications are that in a future warmer climate, nutrient concentrations may have to be reduced substantially from present values in many lakes if cyanobacterial dominance is to be controlled.

“…There is a need to design adequate indicators for ecological assessment of these waterbodies that will allow such discrimination (Elliott and Quintino 2007;Pusceddu et al 2007;Tagliapietra et al 2009). The monitoring methods developed for European coastal waters have often been designed for long-term and large-scale application across the whole Mediterranean Basin level (Moss et al 2003;Peeters et al 2009). …”

North African coastal lagoons are unique ecosystems that often suffer degradation due to human activities. Therefore, monitoring methods are required to identify stressors and assist with the management of these valuable and often understudied ecosystems. A synthetic indicator of water ecological quality would be desirable for regular monitoring of these ecosystems under pressure. In 2008 an optical procedure was developed and applied in Ghar El Melh, a Tunisian lagoon which has been increasingly impacted by pollutant loading, especially from agriculture. In situ hyperspectral irradiance was measured at several stations, from which the apparent optical properties (AOPs), namely the irradiance attenuation coefficient K(λ) and the reflectance ratio R(λ), were obtained in order to relate them to water composition, in terms of light-attenuating substances (LASs). The significant relationships observed between R and LAS values enabled the application of a hyperspectral optical classification, which effectively highlighted threatened sectors of the lagoon. The pattern of differing water quality across the lagoon system that was derived from the hyperspectral classification agreed well with that obtained from a conventional optical classification that included AOPs and LASs. We suggest that hyperspectral analysis and classification is a useful monitoring tool for the assessment of change in coastal lagoons, and perhaps also in other shallow-water ecosystems.

“…Perbedaan kecerahan di ekosistem danau dipengaruhi oleh kekeruhan berupa padatan tersuspensi (Effendi, 2003), kepadatan populasi fitoplankton dan zooplankton, jumlah bahan organik terlarut (Torremorell et al, 2007), serta musim (Mola & Gawad, 2014). Berdasarkan kategori kecerahan perairan (Peeters et al, 2009), danau Situ Gintung tergolong buruk atau memiliki kecerahan rendah.…”

A B S T R A C TThe changes in the physicochemical of waters in the lake ecosystem caused by seasonal variation, anthropogenic and industrial wastes impact the gastropod community. This study aimed to determine the physicochemical parameter of waters, community structure and distribution of gastropod, and the correlation between those two in the dry and rainy seasons. We conducted this research in the lake of Situ Gintung located in Tangerang Selatan, Banten, Indonesia during the dry season (May to August 2015) and the rainy season (February to April 2016). Statistical analysis showed the physicochemical parameter of waters in both seasons has no different, while the gastropod showed a slight difference in occurrence based on the season, in which rainy season had the highest occurrence. Canonical Correspondence Analysis (CCA) suggested that gastropods occurrence were affected by the light intensity in the rainy season and the temperature in the dry season.
