Abstract:
The world’s population has already reached almost 8 billion people and continues to grow rapidly. Environmental and climatic changes caused by human activity are continuously progressing; therefore, their impact on the further development of civilization has become one of the most acute and widely discussed problems.

Abstract:
Springs are important habitats and determine the characteristics of headwater streams. However, they are rarely studied and usually not included in monitoring programs. Our study characterizes the sources of three large rivers and contributes to the knowledge about the biggest East European drainage divide. The catchment area is characterized by dense forests, which are rich in swamps and mires. The paludified catchment is typical for the rivers in this region and it is also determining the physicochemistry of the water. We provide a first dataset about the physicochemical conditions of the sources of Volga, Dnieper, and Western Dvina, which should build a basis for further analyses of the springs of these large rivers. We suggest that monitoring the sources of the large rivers in the Valdai hills should be considered as an extension of the existing monitoring programs.

Abstract:
Today, most developed and developing countries utilize renewable energy to meet their needs. The use of renewable energy prevents environmental pollution. A concern of the governments is to deal with environmental pollution. Iran as a major oil-producing country has increasingly paid attention to non-fossil energy resources, in particular renewable energy sources for its longer-term energy plans. In this paper, the types of renewable energy used in electricity generation in Iran have been studied. Studies show that during the last 20 years, 1.5% of the amount of electricity produced in Iran is supplied by renewable energy. Iran also has a much greater potential for utilizing renewable energy. By 2020, Iran has a potential of 42000 MW use of renewable energies. However, the capacity of renewable power stations constructed in Iran is 800 MW. Different regions of Iran have high wind, solar and geothermal energy potential, which has not been used enough to meet electricity needs.

Abstract:
Limited access to fodder with fair nutritive characteristics especially during dry periods is a challenge to livestock farming. However, it is envisaged that evergreen bamboo with year-round litter production and high nutritive characteristics, may provide a valuable supplementary source of feed. In Ghana, bamboo use as fodder is largely unknown and efforts to promote its use will require an understanding of base feed quality and results disseminated. Therefore, a field fodder quality experimentation using twenty Djallonké kids (juvenile goats) of 1-year-old with a mean initial weight of 13.77 ± 1.16 kg for the trial and allotted to four dietary treatments in a completely randomized block design with five replicates per treatment was conducted. The study sought to assess the effect of leaves of two bamboo species (Oxytenanthera abyssinica and Bambusa balcooa) as a feed supplement to goats fed on basal diets of Pennisetum purpureum and Brachiaria decumbens. The fodder quality results indicated that nutrient composition and in vitro gas production of the treatments varied significantly among the grasses and the bamboo supplement. The highest crude protein and in vitro gas production was observed in O. abyssinica. Besides, O. abyssinica diets recorded the highest daily gain and the lowest feed-to-gain ratio. The treatment effect was significant on blood variables measured. Bamboo leaves are a viable feed supplement for goats as shown by their nutrient profile and positive influence on the growth performance of goats. Hence, the leaves of any of the bamboo species could be used as supplemental feed for goats.

Abstract:
The term ocean acidification (OA) is known as the lowering in the pH of the ocean by absorbing carbon dioxide (CO2) from the atmosphere over a continued period of time. Various factors such as land use change and the burning of fossil fuels increase the concentration of CO2 which was absorbed by the ocean at a factor of 30% which causes many chemical reactions [1].

Abstract:
Whether we like it or not, ours will be a century where the governance and economic agenda will be dominated by the task of adapting to climate change. With the early effects of climate change already starkly visible, and their escalations over the coming decades already locked in, adaptation is no longer a choice but an imperative. And nowhere in the world is there a greater urgency to set out a coherent and comprehensive agenda for adaptation, we believe, than in Africa.

Abstract:
Nototriche hartwegii A.W. Hill, 1909 (Malvaceae: Malvales), is recorded for the first time in the province of Bolívar, in the wetlands of the Andean plateau of the Chimborazo Fauna Production Reserve (RPFCH). With this record, the endemic and limited distribution of this species to the wetlands of southern Ecuador, between 4100 and 4400 m.a.s.l., specifically in the provinces of Cañar and Azuay, is extended to the moorlands of central Ecuador.

Abstract:
This paper presents the first molecular study on Calligonum comosum L. ‘Her (Polygonaceae) in the Kingdom of Saudi Arabia, due it’s known to be part of Saudi Arabia’s flora, as a famous medicinal plant, it has several other uses, as it is palatable as animal feed, and dune stabilization, and to increase soil organic matter content. And it has been included on the endangered species list due to its frequent use. Twenty-five C. comosum samples were collected from five different populations from their natural environment and screened using Inter-Simple Sequence Repeat (ISSR) markers. Eleven ISSR primers amplified 975 reproducible bands of which 495 were polymorphic, and polymorphism of genetic variation between species was 50.8%. This ratio is considered high Among C. comosummembers from multiple populations, this ratio is an indication of the quality of genetic diversity within and between C. comosum populations, which is of great importance for the preservation of the plant. As considered ISSR markers are an effective tool to provide good information for the genetic diversity available in C. comosum inputs from different populations, and the results of this study will help to understand genetic variation and evolutionary dynamics in C. comosum and expand the genetic base for breeding wild species. That additional selection of inputs in each species to assess genetic diversity leads to more useful and reliable results.

Abstract:
Eco-evolutionary community genetics refers to the study of population genetics at multispecies levels since a single species evolves genetically through interactions with other species. The aim of this paper is dynamical modeling of interspecific quantitative trait loci (QTL) under slight and hard multilevel selection to investigate eco-evolutionary genetic relationships among QTL of multispecies. It was found that the simplex explained the intergenomic epistatic QTL (IEQ) dynamics in a discrete-time model according to Wright’s manifold. Besides, the generalized gradient system on the simplex demonstrated the IEQ dynamics in a continuous-time model. The outcomes of slight and hard multilevel selection on the expressions of IEQ in species were explained by the gradient operator of the mean multilevel fitness. IEQ analysis was integrated into community genetics according to Lande’s assumptions, so for slight multilevel selection, the geometric average of the mean multilevel fitness specified Wright’s idea of adaptive topography. The dynamical system for phenotypic eco-evolution under a hard multilevel selection gradient was studied and the relative mean multilevel fitness of two species was estimated.
