“…Agriculture and livestock classes may have contributed to the levels of this parameter, at Á lamos and Lucefécit. Currently, the results do not reveal a clear significant correlation among LULC and BOD5, however this kind of linkage has already been observed in other studies [27,[58][59][60].…”

“…In general, the sediments presented TN s concentrations higher than the SEL (TN SEL > 0.48%; [69]) during the wet period of 2017. Despite this scenario, the TNs concentrations have been presenting a slight rising trend over time, which can be linked with the intensification of agriculture practices, as reported elsewhere [60].…”

“…The TN levels presented high spatial and temporal variability, ranging between 0.01 and 2.75 mg/L, Lucefécit being the location with the greater values detected. In fact, the highest values of TN, at the water column, occurred at Lucefécit in the wet period 2018, probably due to the runoff from agriculture practices and livestock activities, the LULC classes more representative in its drainage basin, as already observed in other Mediterranean reservoirs [60]. On the other hand, TP achieved the highest concentrations in the water column during the dry period 2017 at Lucefécit, surpassing the limit for the good ecological potential (TP ≤ 0.07 mg/L; [55]).…”

“…These locations, with the lowest depth and with considerable external sources of nutrients, as farming pigs and intensive agriculture activities, also showed the lowest euphotic zones. In fact, in a study carried out on 50 surface water bodies in Greece, the most impacted lakes by agricultural and urban classes had the lowest secchi depth [60]. The increase in phytoplankton also contributed to the lower levels of euphotic zone observed, supported by negative correlation between Chl-a and euphotic zone (R = −0.814; p < 0.01).…”

Nowadays, the Mediterranean freshwater systems face the threat of water scarcity, along with multiple other stressors (e.g., organic and inorganic contamination, geomorphological alterations, invasive species), leading to the impairment of their ecosystem services. All these stressors have been speeding up, due to climate variability and land cover/ land use changes, turning them into a big challenge for the water management plans. The present study analyses the physicochemical and phytoplankton biomass (chlorophyll-a) dynamics of a large reservoir, in the Mediterranean region (Alqueva reservoir, Southern Portugal), under diverse meteorological conditions and land cover/land use real scenarios (2017 and 2018). The most important stressors were identified and the necessary tools and information for a more effective management plan were provided. Changes in these parameters were further related to the observed variations in the meteorological conditions and in the land cover/land use. The increase in nutrients and ions in the water column, and of potentially toxic metals in the sediment, were more obvious in periods of severe drought. Further, the enhancement of nutrients concentrations, potentially caused by the intensification of agricultural activities, may indicate an increased risk of water eutrophication. The results highlight that a holistic approach is essential for a better water resources management strategy.

“…The hydrogen and oxygen isotope values of river and spring water indicated supply mainly by glaciers in the east and by precipitation in the west. Mavromati et al (2018) analyzed physicochemical data from the national monitoring network of waters in Greece, which comprises 50 natural and artificial lake water bodies. The aims were to present the pressures resulting from land cover and population density, and to link catchment area features with physicochemical parameters.…”

The objective of this study was to investigate the effects of substrate type in macroinvertebrate assemblages in Mediterranean lakes. Samplings have taken place in the littoral zone of 21 lakes in Greece, between 2015 and 2018. We compared benthic macroinvertebrate assemblages among three substrate types of their littoral zones; sandy, covered with macrophytes and stony substrate. Benthic macroinvertebrate assemblages at sites with extended macrophyte cover differed only slightly in composition and abundance from the ones found in stony and sandy substrates. Coenagrionidae were indicative of sites covered with macrophytes and Oligochaeta and Erpobdellidae were representative of stony substrates. The type of substrate proved to be a statistically significant factor influencing the number of benthic macroinvertebrate taxa, the relative abundance of Oligochaeta and the relative abundance of Odonata. In the context of designing site-adapted management measures, priority could be given to the conservation and restoration of aquatic vegetation in lake littoral zones, which host rich macroinvertebrate assemblages with abundant taxa of Odonata.
