“…Relative to seas and oceans, freshwater habitats are more drastically impacted by changes to climate, especially due to changes to temperature and flow, and climate change is projected to strongly affect freshwater fish communities (Buisson, Thuiller, Lek, Lim, & Grenouillet, ; Graham & Harrod, ; Harrod, ; O'Reilly, Alin, Plisnier, Cohen, & McKee, ; Radinger et al, ). Combined with other anthropogenic impacts (e.g., land use change and thermal pollution; Radinger et al, ; Raptis, Boucher, & Pfister, ), climate change will restrict or redraw thermal envelopes, contribute to population declines and local extinctions, and result in shifts in the distribution of species (Booth, Bond, & Macreadie, ; Ficke, Myrick, & Hansen, ; Filipe, Lawrence, & Bonada, ; Woodward, Perkins, & Brown, ). Riverine fish species losses due to climate change and reduced water discharge are predicted to reach 75% in some river basins, such as those of rivers Parnaíba (Brazil), Saloum (Senegal), and Cauvery (India; Xenopoulos et al, ).…”

Climate change is expected to strongly affect freshwater fish communities. Combined with other anthropogenic drivers, the impacts may alter species spatio‐temporal distributions and contribute to population declines and local extinctions. To provide timely management and conservation of fishes, it is relevant to identify species that will be most impacted by climate change and those that will be resilient. Species traits are considered a promising source of information on characteristics that influence resilience to various environmental conditions and impacts. To this end, we collated life‐history traits and climatic niches of 443 European freshwater fish species and compared those identified as susceptible to climate change to those that are considered to be resilient. Significant differences were observed between the two groups in their distribution, life history, and climatic niche, with climate‐change‐susceptible species being distributed within the Mediterranean region, and being characterized by greater threat levels, lesser commercial relevance, lower vulnerability to fishing, smaller body and range size, and warmer thermal envelopes. Based on our results, we establish a list of species of highest priority for further research and monitoring regarding climate‐change susceptibility within Europe. The presented approach represents a promising tool to efficiently assess large groups of species regarding their susceptibility to climate change and other threats, and to identify research and management priorities.

Life cycle assessment (LCA) is implemented to various processes with a strict exception for naval platforms and warships. Thus, the recent studies for life cycle analysis of military ships are limited. LCA is a holistic method based on developing an optimization between environmental performance, cost-benefit balance and usability. LCC is a supporting subsection of LCA implemented to the analysis in order to calculate the probable costs during whole phases of a product. In this study, LCA and LCC are implemented to a naval platform and a calculation, which is based on escalation, is realized to compare the maintenance costs and initial cost for all life cycle of the platform. A generic warship is selected and yaw damping system of the ship was chosen for implementation of LCA and LCC. It is accepted that the systems and devices are used 1500 hours during cruising and 7260 hours during hoteling. First, the initial cost of yaw damping system is calculated, then, costs of long term maintenance with and without escalation are considered. In the final part, the profit gained by recycling of yaw damping system is calculated. The results has shown that an extra cost of 38 % and 19 % for operation and maintenance and total cost, respectively, must be added according to escalation calculations. While initial cost and operation and maintenance costs have 51 % and 49 % of total costs without escalation, the share of initial cost decreases to 43 % and the share of operation and maintenance increases to 57 % with the utilization of escalation.

“…Power plants discharge very large volumes of cooling water that have accumulated much heat in the cooling process, raising the temperature of the water into which it is discharged [1][2][3]. Waste heat discharge from thermal power plants is one of the main causes of thermal pollution of water [4][5][6][7][8][9]. This thermal discharge pollution is becoming an increasingly serious environmental problem.…”

A 3-D thermal discharge numerical model based on the Navier-Stokes equation, the k-ε turbulence model, and the temperature diffusion-controlled equation was developed to simulate the 3-D distribution of thermal discharge along a river-type reservoir under different discharge conditions, hydrological conditions and reservoir water levels. Results showed that the thermal discharge from the power plant would have a smaller effect on a deep-water reservoir. Neither 1ºC, 2ºC nor 3ºC isotherm appear in any scenario conditions. For dam water depths of 155 m and 175 m, a small envelope area of 0.05ºC isothermal line was predicted. The isothermal lines of 0.05ºC and 0.1ºC covered a small area in all scenario conditions. The temperature increase 500 m downstream of the discharge point was predicted to be less than 0.05ºC during dry seasons. The predicted stability time of the temperature increase in each layer was 20 days. It evidences the thermal impact intensity and the extent is different under three scenario conditions. The predicted space-time distribution of the cooling water and the temperature increase provide scientific bases for designing water intake and water management. In the future, the influence of thermal discharge on water quality and aquatic organisms of the reservoir will be discussed based on the simulation results of this study, that is, the variation law of water temperature caused by thermal discharge.
