Investigating the challenges of biodiversity management of Sefidkuh Khoramabad protected area by using the Delphi method

The main source of economic and agricultural development of all countries is natural resources. The dependency of local communities on natural resources and protected areas, and the excessive exploitation of forests and pastures and wildlife, has led to the destruction and degradation of biodiversity. The basis of managing protected areas in Iran is based on protection, research, training and entertaining, but in reality, protection is only limited to one fifth of these areas, which are safe. There is no management on the surrounding lands (the danger of islandization). Therefore, the purpose of this study is to identify and investigate the challenges of biodiversity management of Sefidkuh Khoramabad Protected Area by using Delphi method. This is a descriptive-analytic study. Thus, after identifying the available biodiversity and field visits and identifying the threats in the region, questionnaires were designed by experts regarding the Likert scale and were given to experts and specialists.The questions were answered by the experts and were analyzed by SPSS Software, the answers were prioritized by regression and descriptive analysis of existing threats and explained its relationship with four research variables (academic degree, familiarity with the region, job and employee of the organization). Then, this priority was organized as a questionnaire, and was given to the expert for final approval and identification of the main threats. Finally, some suggestions and recommendations are given.Keywords: Biodiversity, Challenges, Protected Areas, Sefidkouh, Prioritizatio

Investigating the effects of heavy metals in the waste leachate on the groundwater quality near the landfill (case study: Landfill of Saravan, Rasht)

The main and fundamental scientific reason of scientific community attention to the issue of leachate pollution and its treatment is the possible danger of contamination of water, soil and to some extent air. The reason is that the leachate of landfill in fact is acomplex waste withhigh pollution. Today, in our country, especially in northern areas due to high groundwater levels, the problem of waste disposal and the effects of their leachate entering alluvial groundwater and aquifer contamination downstream based on hydrodynamic thickness in the movement of water is highly regarded andentering a considerable amount of pollution (nitrates, heavy metals, etc.) to underground water sources used for drinking and agriculture, in the long term become a social problem. Saravan landfill is located on 15 km road Rasht of to Tehran is like a black spot in the in the green Hyrcanian forest and receives more than 500 tons of waste daily from provinces cities,particularly Rasht which with no environmental assessment for selected waste disposal, waste disposal is inadequate in Saravan and because of evaporation, fermentation and decomposition of the waste and leachate percolation into the soil and water resources it is associated with high pollution and unleashed leachate river in the heart of nature and based on the ranking of Index criteria it is unacceptable. In this study, sampling was conducted in 2 upstream wells, 3 downstream wells of Saravan landfill then the samples were analyzed by atomic absorption.  The results indicate the presence of heavy metals (chromium - lead – zinc -iron - manganese) in water of downstream wells of the landfill compared to upstream wells and the control wells or in other words, it was significantly more than the control and upstream wells and the average concentrations of Pb, Cr, MN, Fe higher than drinking water standards and the mean concentration of MN and Cr in the research water wells was more than standard water for irrigation and agricultural. It shows the leachate percolation into soil and ground water that has been polluted the nearby water of the landfill.Keywords: Groundwater, Landfill, Leachate, Heavy Metals, Sarava

Genomic-based breeding for climate-smart peach varieties

Improving the performance of peach varieties in the context of climate change requires multiple approaches. Not only will climate change alter plant phenology, but it will also drive negative effects of several biotic and abiotic stressors. The challenge is to improve adaptation of varieties to a changing environment, while maintaining organoleptic qualities of the fruit. This chapter focuses on the progress in genomics-assisted breeding in peach to break barriers in conventional breeding. Breeding climate-smart (CS) peach trees requires the identification of CS traits used in the adaptation to high levels of temperature, CO2, water deprivation and biotic stress. Relevant CS traits, such as those that control flowering time (chilling and heat requirements), biotic and abiotic stress tolerance (pests and diseases; water-nutrient efficiency), require prioritization. Here, we review classical mapping and breeding of peach varieties, the progress and limitations of the used of marker-assisted selection and breeding (MAS and MAB, respectively) in expression of traits, such as fruit quality and stress tolerance, and describe the rationale for the use of molecular breeding.EEA San PedroFil: Gogorcena Aoiz, Yolanda.
