It was found from May to September, in streams, lakes and ponds. All specimens examined were macropterous. Limnoporus rufoscutellatus is considered monomorphic (long-winged) and univoltine (Vepsäläinen 1974b, Vepsäläinen & Nieser 1977, Andersen & Spence 1992). Distribution. Widespread in the Palaearctic Region, but absent in the Iberian Peninsula, northern Africa and the Middle East. In the Nearctic Region, it is known from Alaska and northwestern Canada (Andersen 1995, Kanyukova 2006, Damgaard et al. 2014).

No full textAbstract
During a field campaign in the Strei River basin in August 2014, seven suitable habitats for aquatic and semi-aquatic true bugs were identified from the confluence of the Strei River with the Bărbat River down to the confluence with the Mureș River. Forty-eight individuals belonging to 15 species and nine families of aquatic and semi-aquatic true bugs were sampled. We mention two species considered rare in Romanian fauna: Hebrus montanus and Microvelia pygmaea. The statistic-mathematical analysis showed the similarity of the true bugs’ communities from habitats with similar conditions, as well as the relation of each species with particular habitat conditions, emphasizing the fact that Gerris lacustris is present in the majority of the investigated habitats, while the rest of the species are conditioned mostly by the ratio between the areas with open water and those covered by aquatic vegetation.</jats:p
Water Sustainability in the Context of Global Warming: A Bibliometric Analysis
No full textSustainable water use is becoming a key problem in the present time, since global warming is having a strong impact on usable water resources. This study aims to provide a systematic bibliometric analysis on water sustainability in the context of global warming, in order to provide a clearer view on the existing research trends and to find eventual gaps in research that can be exploited in the future. The selection and analysis of the most relevant papers discussing the chosen topic pointed out a strong increase in research in the last period, dominated by US scientists and research entities, with researchers focusing on either the present impact of global warning on water sustainability and its effects on water supply and ecosystem functioning, or on problem solving and creating a framework for water sustainability in the context of global warming, or on the future perspectives and potential solutions for achieving water sustainability in the future period. The study pointed out that only 6% of the article regarding water sustainability include information about global warming, with an increasing trend in the latter period in both the number of articles and citations, but the field of study seems to be incipient, with a large number of journals publishing a very low number of articles. The main drawbacks identified were the orientation of a large majority of the studies on present day problems and not on future approaches, the complete lack of studies regarding the role of preserving natural habitats or of spontaneous renaturalization, as well as the relative absence of including cultural aspects in addressing water-sustainability issues

(2000), Ilie (2001, 2003, 2007), Ilie & Davideanu (2002), Davideanu et al. (2004), Ilie & Ban-Calefariu (2010). Remarks. In Romania, it was identified at 12 sites at an elevational range of 95–384 m a.s.l. (Fig. 1). It was found from April to December in streams, bogs and ponds. The apterous/macropterous ratio was: 0.4: 0.6 (total 6/ 9). In the Alps, G. asper is considered univoltine (Nieser 1981), whereas in Hungary it is bivoltine (Vepsäläinen 1974a). Probably, it is overwintering both as long- and short-winged morphs. Distribution. West Palaearctic: central and southern Europe, Ukraine, Caucasus, Anatolia, Israel, Syria, Iran, Afghanistan, Morocco, and doubtfully in Algeria (Andersen 1995, Damgaard et al. 2014).
