Long-term observations of lake water level are essential to our understanding of the evolution of Tibetan lake system. CryoSat-2 radar altimetry data over the Tibetan Plateau (2010–2014, P2) is used to extend lake level measurements from ICESat laser altimetry (2003–2009, P1). This study evaluates the performance of CryoSat-2 data by comparing with gauge-based water levels that are calibrated b...
Cvetkoska et al. present a diatom record of high quality, alongside various geochemical proxies, from a c. 92ka lake sediment sequence retrieved from Lake Ohrid (part of the SCOPSCO project). The main purpose of the research is to compare this record to a previously published diatom record from the adjacent Lake Prespa (to which Ohrid is hydrologically connected) in order to compare system resi...
Background and Objectives: Since the students are the most important part of university, their satisfaction with educational services is necessary to improve the quality of system. Electronic registration has initially been conducted since 2003 in Iranian universities; therefore, it is a necessity to carry out a research to explore the students view points. Materials and Methods: We performed ...
Access to technology in the upstream oil and gas industry is one of the most challenging issues. In this industry, in order to be able to apply the desired effects of technology in the economic and development dimension, in the decision-making process, the choice to acquire technology must be such as to avoid repeating the ineffective approaches of the past. However, the most divisive And expli...
Nature has always proven that it is able to overcome its problems. However, human manipulation has led to environmental degradations. The dryness of a thousand-year Urmia Lake (a brinewater lake in Iran) is an example of environmental degradation that happened due to successive droughts and construction of dams on the basin of this lake. This study examines methods for the revival of Urmia Lake...

Background and objective: Access to information is one of the pillars of a smooth and productive information flow which would provide the best opportunities for an effective Information management. Thus, it is essential to acquire the knowledge about how to access information and ways to improve it, especially in the field of natural disaster management (NDM), which is based on decisions making...
Evolutionary innovations, traits that give species access to previously unoccupied niches, may promote speciation and adaptive radiation. Here, we show that such innovations can also result in competitive inferiority and extinction. We present evidence that the modified pharyngeal jaws of cichlid fishes and several marine fish lineages, a classic example of evolutionary innovation, are not univ...
Examples from across Canada have shown that when the exploitation of lands and resources grow in profitability the cultural landscape of aboriginal communities stands at risk unless a process of exclusion or a means of adaptation can be established. As a means of adaptation, aboriginal communities are entering into co-operative management agreements with government and industry in an attempt to...
Lake Clark is an important nursery lake for sockeye salmon (Oncorhynchus nerka) in the headwaters of Bristol Bay, Alaska, the most productive wild salmon fishery in the world. Reductions in water clarity within Alaska lake systems as a result of increased glacial runoff have been shown to reduce salmon production via reduced abundance of zooplankton and macroinvertebrates. In this study, we rec...
