Microbial Role in the Carbon Cycle in Tropical Inland Aquatic Ecosystems
Aquatic microorganisms are tidily related to the carbon cycle in aquatic systems, especially in respect to its accumulation and emission to atmosphere. In one hand, the autotrophs are responsible for the carbon input to the ecosystems and trophic chain. On the other hand, the heterotrophs traditionally play a role in the carbon mineralization and, since microbial loop theory, may play a role to carbon flow through the organisms. However, it is not yet clear how the heterotrophs contribute to carbon retention and emission especially from tropical aquatic ecosystems. Most of the studies evaluating the role of microbes to carbon cycle in inland waters were performed in high latitudes and only a...
Progress in Ecological Stoichiometry
Ecological stoichiometry concerns the way that the elemental composition of organisms shapes their ecology. It deals with the balance or imbalance of elemental ratios and how that affects organism growth, nutrient cycling, and the interactions with the biotic and abiotic worlds. The elemental composition of organisms is a set of constraints through which all the Earth’s biogeochemical cycles must pass. All organisms consume nutrients and acquire compounds from the environment proportional to their needs. Organismal elemental needs are determined in turn by the energy required to live and grow, the physical and chemical constraints of their environment, and their requirements for relatively...
Engenharia & Ciências Ambientais : contribuições à gestão ecossistêmica
Engenharia e Ciências ambientais: contribuições à gestão ecossistêmica", escrito por muitas mãos, nos leva pelos caminhos metodológicos de um conjunto de estratégias para minimizar impactos negativos, de diversas naturezas, na utopia de um ambiente sustentável. Com as pesquisas e debates descritas pelos autores, evidencia-se a necessidade da luta permanente e resiliente para a busca de soluções apropriadas, na gestão consequente e com pertencimento, em prol da qualidade ambiental. A qualidade das pesquisas com foco na sustentabilidade ambiental no Brasil perpassa, inevitavelmente, por estratégias e metodologias que viabilizem as parcerias interinstitucionais e pelo fortalecimen...

Aquaculture, Resource Use, and the Environment
Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.
Ecology of Shallow Lakes
Ecology of Shallow Lakes brings together current understanding of the mechanisms that drive the diametrically opposite states of water clarity, shown by the cover paintings, found in many shallow lakes and ponds. It gives an outline of the knowledge gained from field observations, experimental work, and restoration studies, linked by a solid theoretical framework. The book focuses on shallow lakes, but the lucid treatment of plankton dynamics, resuspension, light climate and the role of vegetation is relevant to a much wider range of aquatic systems. The models that are used remain simple and most analyses are graphical rather than algebraic. The text will therefore appeal to students, scien...
Eurasianism and the European Far Right
The 2014 Ukrainian crisis has highlighted the pro-Russia stances of some European countries, such as Hungary and Greece, and of some European parties, mostly on the far-right of the political spectrum. They see themselves as victims of the EU “technocracy” and liberal moral values, and look for new allies to denounce the current “mainstream” and its austerity measures. These groups found new and unexpected allies in Russia. As seen from the Kremlin, those who denounce Brussels and its submission to U.S. interests are potential allies of a newly re-assertive Russia that sees itself as the torchbearer of conservative values. Predating the Kremlin’s networks, the European connections ...

Marine Metagenomics
This book presents the state-of-art marine metagenome research and explains the method of marine metagenomic analysis in an easy-to-understand manner. Changes in the marine environment due to global warming and pollution have become a major global problem. Maintaining a healthy marine ecosystem requires advanced environmental monitoring and assessment systems. As such, the book presents a novel metagenomic monitoring method, which has been developed for comprehensive analyses of the DNA of microorganisms living in seawater to further our understanding of the dynamics of the marine environment. The book can be used as a primer for new researchers and as a manual on experimental methods.
