Bio-fuels have received prime focus of these efforts. First and second generation biofuels were unsuccessful due to extensive cropping land and water requirements. Presently, microalgae has been considered as the source of third generation biofuels as it can be produced on large scale without any detrimental impact on environment and arrest carbon emissions as well. For ensuring cost effective and sustainable production of microalgae, wastewater generated from municipal, agricultural and industrial activities may be considered as a potential medium for algal growth. The present study focuses on the simultaneous wastewater treatment and biofuel generating potentials of microalgae as well as advantages and disadvantages of the same. This review also discusses possibilities of rendering microalgal biodiesel production economically more beneficial than petro diesel and highlights the future perspectives by compiling initiatives taken so far.

When the first edition of Richard Dawkin’s book The Selfish Gene was published (1976), the view that “altruistic behaviour” in animal populations is a common phenomenon was widely accepted. Dawkins questioned this interpretation and proposed his concept of the selfish (i.e., immortal) gene, which explains a number of phenomena, such as the evolution of anisogamy, or the roles of males vs. females during sexual reproduction in gonochorists (birds, mammals). In this 40th-2016-anniversary-analysis of Dawkins book I argue, based on observations on populations of “egoistic”, (hermaphroditic) freshwater leeches of the genus Erpobdella characterized by intraspecific cocoon cannibalism, that his theoretical deductions were basically correct. In addition, sex-gender-conflicts in leeches are discussed with reference to the avoidance of the female role in populations of these hermaphrodites. The idea of the “immortal (i.e., selfish) gene” is attributed to the 19th-century-work of the German zoologist August Weismann, and the “Post-Dawkinsian” concept of intragenomic conflicts is addressed.

The sea level has continuously fluctuated over geologic time. The best evidence for eustatic sea level changes was provided by geologists who studied the shifts of shorelines and recoveries resulting in sedimentary deposits also referred to as sequence stratification. Continuing global warming raised the question whether or not the melting of the glacial ice and snow reserves could result in earlier high sea levels. To answer the question the sea levels were turned to volumetric data. This was achieved by calculations i) using the radii of Earth, with and without the geometric radius of the geoid Earth, ii) selecting among data for an average sea depth, iii) comparing the volumetric values of best fitting values. Upon reliable data within 0.5% deviation were obtained, linear correlation was found between the volumes of sea that would be needed to achieve different sea levels. The calibration curve revealed that 80% (20 A 106 km3) melting of the available fresh water reserves of polar glaciers, ice sheets and permanent snow (100%, ~25 A 106 km3) would cause about 50 m sea level rise. These calculations prove that earlier high (200-300 m) sea level elevations will never be obtained due to the global loss of water to the outer space. In connection with the water deficiency, the osmotic gap between the osmotic concentration of land vertebrates (0.3 Osm) and that of sea (1.09 Osm) is reflecting the salination of ocean. Salinty changes were distinguished as short term dilution periods and a long-term salination process. Long-term salination contributed by human pollution of sea and fresh water will seriously impact future life on Earth.

The study presents the analysis of polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/F) and dioxin-like polychlorinated biphenyls (dl-PCB) in fish and seabirds from the Baltic Sea area and the Arctic region (the Svalbard Archipelago). Long-time studies revealed no significant temporal trends in PCDD/F and dl-PCB concentrations in fish from the Baltic Sea. Trace amounts of PCDD/F were detected in the Arctic fish as an evidence of their anthropogenic sources from the temperate zone, however congener profile in the cod was entirely different than in the Baltic fish. On the contrary, both concentrations and profiles of dl-PCB were comparable in cod from the Baltic Sea and from the polar region. PCDD/F`s congener profile in African penguin`s tissues breed in captivity and fed only by herring exhibited a clear resemblance to the profiles measured in herring. This indicates a relevant impact of diet (fish) on PCDD/F`s level in seabirds. Diet impact on the further transfer of these xenobiotics in the trophic chain, evidenced in the presented study, appears to be of the particular relevance due to the human health.

Although the distribution of fluvial knickzones, as an important geomorphic feature in bedrock river morphology, has been studied by many investigators, the role of them in examination of tectonic activity has not been well investigated [1], specially based on its comparision with movement potential faults over a broad area. This study examines the tectonic activity of Khuzestan province, South West Zagros, by considering two different parameters: distribution of the fluvial knickzones along Mountain Rivers and evaluation of faults activity in the study area. A segment of a river long-profile that is steeper than adjacent segments is commonly referred to as a knickzone or a knickpoint if it is visibly steeper than the trend of the longitudinal profile. Knickzones are often observed along bedrock rivers and the most visible form is a waterfall. Knickzones are supposed to be a response to base-level changes or to alternations of local lithology [2]. Upstream migration of knickzones has been argued to cause rapid river incision and result in the formation of terraces and instability of valley-side slopes. Knickpoint evolution on a river can provide evidence for uplift of plate margins [3]. Knickpoints can be used as geomorphic markers in steep, rapidly eroding landscapes that commonly lack datable river terraces [4]. In this paper we use the method that was proposed by Hayakawa and Oguchi [5] to extract knickzones in broad areas using DEMs (Digital Elevation Models) and GIS (Geographical Information System). DEM analysis of the longitudinal profiles of rivers permits quantitative, reproductible, and efficient identification of knickzones. The obtained inventory of knickzones will provide a basis for objective analyses of the distribution of knickzones.

The climate of the planet depends on the circulation of water in nature. The main driving force of the process is the Biota-the main consumer of water. Millions of years of interchange of water between the sky and the earth were created a harmonious balance of the water change. Man, increasing the comfort of its existence, it takes away from the nature of the territory, uses water notonly for drinking. Critical link in the chain of the water cycle decreases the transformation of water flora and fauna. The main source is the moisture vapour respiration and waste products of living creatures and plant transpiration. Suffice it to recall that one just one evaporates birch 50-60 litters of water per day. One cow drinks about 100 litters of water for the same time. It is known that a hectare of fertile soil contains 20 tons of underground living creatures, each unit which consumes water and breathes moisture and other properties. About this herd of cows in the 40 head of 500 kg. Multiply all this by the number of birch trees, cows and acres across the planet, the flora and fauna.

Development of antibody production technologies is necessary for diagnostic treatments and drug discovery. In general, mammals are used as host animals to produce antigen-specific antibody. However, such host animals have never produced several specific antibodies because host animals may not recognize foreign proteins. To overcome this problem, we used teleost to produce antibodies because teleost are evolutionally localized in the origin of vertebrates and have an acquired immune system in addition to the innate immune system. In particular, we attempt to produce antibody using “Bubble Eye” as a kind of goldfish (Carassius auratus), which has sacs filled with lymph liquid, as an immune animal. In this study, a recombinant EGFP-His was expressed in E. coli and then injected into Bubble Eye’s sac in every two weeks. The antibodies were collected from sac instead of blood. Furthermore, a sandwich dot blotting was developed for detection of antibodies against EGFP-His. The antigen-specific antibodies were detected after 42 days from first immunization.

A new global redox carbon cycle model is suggested. It claims that lithospheric plates’ movement exerts an impact on photosynthesis development. The impact is realized via periodic injections of CO2 coming from zones of plates’ collisions. Carbon dioxide is derived from oxidation of sedimentary organic carbon in thermochemical sulfate reduction proceeding in subduction zones. Carbon turnover is considered as a conversion of the element from the oxidized state (CO2 + HCO3- + CO3-) into the reduced state produced in photosynthesis and in the following transformation. The isotopic data confirm the validity of the model. They explain the observed correlation of carbon isotope composition of sedimentary organic matter with geologic age. It was found that the difference between carbon isotope composition of organic matter and that of coeval carbonates is an analog of the carbon 13C isotope discrimination in photosynthesis used for modern plants. The periodicity of isotopic characteristics correlates with periodicity of climatic changes, mass extinctions, with the irregularity of stratigraphic distribution of rocks rich in organic matter and other periodic events in biosphere.

From the distributional point of view of Penaeid prawn, Indian region in the present study is divided into three main sub-regions viz., East Coast, West Coast including Laccadive-Minicoy Islands and Andaman Islands. Present study also records existence of 79 species in the coastalwater of India. Out of 79 species 9 are endemic, 24 are common in east coast, west coast and Andaman Islands; 16 species are restricted to East coast, 13 are restricted to west coast, 2 are restricted to Laccadiv Islands, 3 species are restricted to Andaman Islands only. Global Analysis shows that most species are distributed within Indo-West Pacific region and only 6 species are distributed up to east Atlantic region. A statistical analysis based on the distribution of prawn shows more moderate similarity between east coast and west coast in India and strong similarity between sub-region 1 and 4 of Indo-West Pacific indicates that the Indian species are more common with Indonesian and Indo-Malaysian than East African species.

A statistical analysis based on the distribution of prawn shows more moderate similarity between east coast and west coast in India and strong similarity between sub-region 1 and 4 of Indo-West Pacific indicates that the Indian species are more common with Indonesian and Indo-Malaysian than East African species.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114985023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
