However, heavy metal sources that have emerged in present-day mainly due to human influence, i.e. industrial activities, agricultural waste, pesticides, use of fossil fuels and traffic, have included a part of heavy metals in the ecosystem. Lake Tuz, together with the entire lake surroundings, water beds and important steppe areas, was declared Turkey’s Specially Protected Area (SPA) in 2001. Our aim in this investigation was to determine the levels of heavy metals such as Chrome (Cr), Copper (Cu), Nickel (Ni), Lead (Pb) and Zinc (Zn) in endemic Salvia halophila grown in different areas of Lake Tuz. The results of the heavy metal contents analyzed at the plant were compared with the international standard levels of heavy metals. The consequences displayed that differing extents of heavy metals are accumulated in S. halophila. The results obtained differed in accordance with the collection time and localities. When...

It is most often diagnosed in childhood and has variable expressions. We report a case of a 7-year-old male child with diminished vision since birth diagnosed as bilateral congenital cataract and superomedial subluxation of lens posted for cataract excision under general anesthesia. The key points of perioperative management included prevention of hypoglycemia, optimal hydration, prevention of thromboembolic episodes, and total intravenous anesthesia.

Chrome removal ratios for two different types namely vegetative cell and endospor of Bacillus thuringiensis used in the biological adsorption is evaluated as cardinal utility and chemical substances used in removal and removal measurement as unit cost. The benefit of chrome VI removal to the human health and environment as unmeasured indirect utility is accepted as data and evaluated in terms of business organization liability, and quantitative data is expressed as verbally. It is determined that 18250 mg/year chrome removal in liter and 50 mg/L/day in average liter are done using either vegetative cell or endospor. Annually chemical input cost is 51.1 € when this data is evaluated. Annually benefit/cost rati...

It is understood that Biological resources are not enough resource as economical which is perceived as inexhaustible goods till this period of time. Therefore it has come into question the conservation and sustainable of these resources. Biological diversity, when to be included to the economical politics, it were started to be taken measures about ensure of the sustainable use is a guarantee of continuity of human life’s continuity and biosphere. Protection measures can be taken as an important condition of success is the possible loss of biodiversity and biodiversity of the economic importance and it is possible to know the value. The possible loss of biological diversity, as it is ecological processes, can cause loss of power which immendable as well as in economic and sociocultural processes. In this context, primarily the goods and services provided by biological diversity of t...

In addition, the visitor profile was determined by examining the differences among socio-economic, cultural and demographic chacteristic of visitors. It was detected whether there is any affect of visitor profile on WTP. According to the analyses, there is a certain conservation value to ensure sustainable use of RBG and hand down the next generations. This value is determined by detecting the participants’ tendency to pay extra except from entrance fee. It is estimated that tendency of each participants to pay extra is the average £5 and it is £20 WTP with the entrance fee and £32,600,000 annually. This condition reflects the total conservation value of RBG. The satisfaction level, educational level, income level, total travel cost and variables can be influential on individuals’ WTP.

Leucojum aestivum contains the alkaloid galanthamine, which is one of the main active substances in Reminyl, a commonly used drug for the treatment of Alzheimer's disease (AD). In this analysis, we estimate that there are 13 million mild to moderate patients with Alzheimer's who use Reminyl. Our results suggest that the market change value of L aestivum required for 1 unit of Reminyl is US$62. The value of total change of galanthamine and L aestivum is estimated to be US$18.6 billion per year. Alzheimer's drugs that use L aestivum are relatively expensive, ranging in cost from US$183 to more than US$400 per month. The minimum annual cost of this is US$2196 per person for "patients with mild and moderate stage AD." The using value of 6 million units of L aestivum bulbs, which is the amount exported from Turkey, is estimated to be US$27 million per year. The determined value for ...

Therefore, actions aiming to maintain viable populations for all threatened or non-threatened species should be based on in-situ conservation of the species. These action plans should be classified as species management, action, conservation, or rescue plans depending on the degree of intervention required. For the future species management plans, in this study, the species belonging to the Fabaceae family (Lathyrus, Astragalus, Vicia, Lotus, Thermopsis), which are in the International Union for Conservation of Nature (IUCN) Red List and under threat of extinction in Turkey, has been reviewed based on the details about (1) their biogeographic regions, (2) habitats, (3) ecological characteristics, (4) potential threats, (5) economic importance, (6) ethnobotanical features and (7) usage opportunities among the people. Additionally, this study evaluates up-to-date records of the species' locations. As a result of the evaluations, the most critical threats to the natural habitats of the species belonging to the Fabaceae family are climate change, overgrazing, land reclamation, haymaking and erosion, deterioration caused by dam construction, and urbanization. Agriculture and anthropogenic habitat loss and degradation are also important threats. According to this study, it is vital to take the necessary conservation measures and develop conservation awareness for the future. Additionally, it is essential to determine these species' usage areas and determine their ecological and economic importance. The preparation of action plans for the conservation of species and the development of sustainable conservation and usage strategies, including genetic diversity, depend on the investigation of these species in all aspects.

Economic valuation techniques, ecological and socio-cultural value criteria were used in the value analysis. In the study, the sum of the flow values for the service functions provide by F. imperialis is calculated as $ 72.96 / year for a per unit F. imperialis. The total economic value of F. imperialis is $ 14,592,000 / year for the 2000 000 unit which annual export quantity of F. imperialis. It has an annual export revenue of $ 52,416 and this estimate value is considerably higher than the annual export revenue. When positive value added created by non-material values in the ecological and socio-cultural processes, wealth and inheritance value are added to this value, F. imperialis' economic value is significantly higher. In addition, biological control value of use from the value functions
