“…Lazoglou and Vagiona (2018) assessed the willingness of inhabitants of the nearby city of Ioannina to pay for environmental actions and projects for the management of the protected area of Lake Pamvotis. The lake, despite its environmental importance and ecological value, is under various anthropogenic pressures (Latinopoulos et al 2018) and Lazoglou and Vagiona (2018) suggested that economic valuation could provide an effective tool for planning processes and decision-making policies for the protection of the environment. Chelli et al (2019) demonstrated the usefulness of long-term plant diversity programmes for the study of species richness and patterns of species assemblages over time in a protected area.…”

Lake Pamvotis is one of the Balkan "ancient" lakes, a Quaternary refugium of great environmental importance and ecological value, that is under various anthropogenic pressures. It belongs to a Natura 2000 Special Area for Conservation and Special Protection Area. Almost in the middle of the lake, there is an inhabited island - one of the two lake islands in Greece – that also attracts touristic interest. Τhe main objectives of the present study are to provide a floristic inventory of the protected island, combining data of two different sampling periods, within a 25 year interval, in order to estimate temporal beta diversity and species turnover of the island’s plant diversity. The value of the absolute and relative turnover rates of the floristic diversity of the island studied are 4.24 and 1.72, respectively and are amongst the higher rates reported for plants. The absolute difference between extinct (E) and immigrant (l) taxa is to a great extent accounted, concerning life forms, by therophytes (1.86), hemicryptophytes (1.56) and geophytes (1.04) and, for habitats, by taxa preferring agricultural and ruderal forms (2.52).

“…A RBMP has been set up [Greek Special Water Secretariat (EGY 2018)] including an extended list of PoM describing the water management necessities for each water body -Lake Pamvotis included-in order to achieve good ecological potential. The most important pressures in the study area come from agriculture and livestock farming, housing and tourism, and hydro-morphological alterations across the littoral zone (Latinopoulos et al 2018).…”

Freshwater ecosystems deliver various ecosystem services providing essential goods and services, on which humans depend. These include vital provision of water for domestic, agricultural and industrial use. Lake Pamvotis, a heavily modified urban lake is providing multiple services but at the same time is under multiple pressures. Setting as target the achievement of the Water Framework Directive (WFD) "Good Ecological Status or Potential" goal and acknowledging the revised River Basin Management Plan's Program of Measures, a set of six alternatives is suggested. For the preferable alternatives' selection, six criteria were adopted whose relations are given through a Driving Forces-Pressure-State-Impact-Responses (DPSIR) conceptual model. Qualitative judgments based on expert opinion are selected to describe the scores of the criteria which are finally evaluated as fuzzy numbers. A hybrid method which incorporates the outranking relation and the right of veto of the ELECTRE III method, and finally the net flow of the PROMETHEE method is developed. The proposed method is based on fuzzy sets and logic in order, firstly to interpret both the monocriterion comparison and the aggregation among the criteria and secondly to enable the evaluation of the criteria with fuzzy scores. The results prioritized the increase of the water quality for the improvement of water related ecosystem services among the other alternatives in all tests. The proposed method is suitable for environmental problems where the evaluation of the scores is not crisp and furthermore, commensurate alternatives are demanded.

“…The automated stations equipped with a sonde were deployed at the littoral zone of the lake at four sites with different habitat characteristics with respect to the local influences from the adjacent land uses, hydrological inputs and the dominant aquatic vegetation (Table 2). In addition, the four sites differ significantly in terms of impacts by human pressures and alterations in lake shore [28]. Site S1 is located at the northern part close to the mouth of a small stream.…”

The metabolic balance between gross primary production (GPP) and ecosystem respiration (R) is known to display large spatial and temporal variations within shallow lakes. Thus, although estimation of aquatic metabolism using free-water measurements of dissolved oxygen concentration has become increasingly common, the explanation of the variance in the metabolic regime remains an extremely difficult task. In this study, rates of GPP, respiration (R) and the metabolic balance (net ecosystem production, NEP) were estimated in four littoral habitats with different macrophyte growth forms (floating-leaved vs submerged) over a 28-month period in lake of Kastoria (Greece), a shallow eutrophic lake. Our results showed that net heterotrophy prevailed over the studied period, suggesting that allochthonous organics fuel respiration processes in the littoral. Temporal variation in the metabolic rates was driven mainly by the seasonal variation in irradiance and water temperature, with the peak of metabolic activity occurring in summer and early autumn. Most importantly, significant spatial variation among the four habitats was observed and associated with the different macrophyte growth forms that occurred in the sites. The results highlight the importance of habitat specific characteristics for the assessment of metabolic balance and underline the potentially high contribution of littoral habitats to the whole lake metabolism.
