Download or read book Wetlands for Remediation in the Tropics written by Tatiana Lobato de Magalhães and published by Springer Nature. This book was released on 2023-01-25 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume provides a review of remediation approaches utilizing aquatic and wetland macrophytes in the Tropics. This form of phytotechnology has exceptional potential as a sustainable nature-based solution, but that potential is not commonly utilized in the Tropics. Constructed wetlands for improvement of water quality are cost-effective, offering affordable solutions for remediation in warm and tropical regions worldwide. The robustness, simplicity, and reliability of treatment wetlands provide efficient long-term operation. Wetlands for Remediation in the Tropics covers theory, provides case studies, and identifies gaps in our current understanding. It highlights why the Tropics differ from temperate regions in this context, particularly concerning differences in climate and species diversity and abundance. Urban, rural, and industrial examples are discussed across 11 chapters. These nature-based solutions, including the concept of ‘Sponge City’, can be applied to tropical areas worldwide and incorporated particularly in highly urbanized regions. The authors, from Argentina, Australia, Brazil, Canada, Colombia, the USA, the Netherlands, Mexico, Pakistan, and Taiwan, all have substantial research experience using wetlands for remediation. The topic of this book is relevant not only to scholars and academics but also to practitioners and government officials from developing countries, where scarce resources and a lack of a qualified workforce are common, but large differences exist in history, culture, regulations, climate, water fluctuations, and vegetation. Although ideas based on experiences from temperate regions can be applied, the Tropics require distinct approaches to developing constructed wetlands for remediation.
Download or read book Networks in Tropical Medicine written by Deborah Neill and published by Stanford University Press. This book was released on 2012-02-29 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networks in Tropical Medicine explores how European doctors and scientists worked together across borders to establish the new field of tropical medicine in the late nineteenth and early twentieth centuries. The book shows that this transnational collaboration in a context of European colonialism, scientific discovery, and internationalism shaped the character of the new medical specialty. Even in an era of intense competition among European states, practitioners of tropical medicine created a transnational scientific community through which they influenced each other and the health care that was introduced to the tropical world. One of the most important developments in the shaping of tropical medicine as a specialty was the major sleeping sickness epidemic that spread across sub-Saharan Africa at the turn of the century. The book describes how scientists and doctors collaborated across borders to control, contain, and find a treatment for the disease. It demonstrates that these medical specialists' shared notions of "Europeanness," rooted in common beliefs about scientific, technological, and racial superiority, led them to establish a colonial medical practice in Africa that sometimes oppressed the same people it was created to help.

The first part deals with the general issue of climate change, the cause and the ways to mitigate and to adapt the built environment for climate change in a number of countries. Part 2 deals with the conceptual ways to mitigate building for climate change. The ways to reduce cooling energy in tropical buildings by means of passive design. Part 3 offers papers that examine the way to overcome disasters in the city caused by climate change. The final part deals with the role of plants in mitigating and adapting built environments to climate change - the use of plants, trees and bushes to directly and indirectly reduce carbon emissions are discussed.
Download or read book Mycorrhiza in Tropical and Neotropical Ecosystems written by Mohamed Hijri and published by Frontiers Media SA. This book was released on 2018-10-19 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhizal symbiosis is a mutualistic association of plant roots and fungi that plays a major role in ecosystem function and diversification, as well as its stability and productivity. It also plays a key role in the biology and ecology of forest trees, affecting growth, water and nutrient absorption and protection against soil-borne pathogens. However, the mycorrhizal research in tropical and neotropical ecosystems remains largely unexplored despite its importance in tropical and neotropical ecosystems. These ecosystems represent more than 0.6% of the total land ecosystems and they have a crucial role in the Earth’s biogeochemical cycling and climate. Threats to tropical forest biodiversity should therefore encourage investigations and inventories of mycorrhizal diversity, function and ecology in tropical latitudes because they concern ecologically and economically important plant species. This Research Topic aims to provide an overview of the knowledge of mycorrhizal symbioses in tropical and neotropical ecosystems. For this Research Topic, we welcome articles that address the diversity, ecology and function of mycorrhiza associated with plants, the impacts of mycorrhiza on plant diversity and composition, the regeneration and dynamics of ecosystems, and biomass production in ecosystems.

This book was released on 2017-01-12 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume we aimed to assess progress in determining the processes by which current patterns of tropical biodiversity were established and are maintained. Tropical regions are highly species-rich and we present studies that have improved our understanding of the generation of that diversity at local, regional and global scales. We demonstrate how diverse fields from molecular phylogenetics, phylogeography, palaeontology and palaeoecology continue to improve our understanding of the natural history of the tropics.

Download or read book The Role of Microbial Communities in Tropical Ecosystems written by Silvia Pajares and published by Frontiers Media SA. This book was released on 2017-01-13 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical ecosystems are different in important ways from those of temperate regions. They are a major reservoir of plant and animal biodiversity and play important roles in global climate regulation and biogeochemical cycling. They are also under great threat due to the conversion of tropical ecosystems to other uses. Thus, in the context of global change, it is crucial to understand how environmental factors, biogeographic patterns, and land use changes interact to influence the structure and function of microbial communities in these ecosystems. The contributions to this Research Topic showcase the current knowledge regarding microbial ecology in tropical ecosystems, identify many challenges and questions that remain to be addressed and open up new horizons in our understanding of the environmental and anthropological factors controlling microbial communities in these important ecosystems.
Download or read book Parasites in the Tropic A New Paradigm Shift written by Veeranoot Nissapatorn and published by Frontiers Media SA. This book was released on 2017-07-06 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The highlight of this eBook is to bring new insights into parasites in the tropic. To achieve that, much has been discussed about risk assessment, infection rates, disease burden, hormones and mechanism of immune response, genetic expression and susceptibility as well as, therapeutic modalities. Authors raised hypothesis, discuss concepts, and show open questions. The remaining important issues to resolve questions within parasites in the tropic – a new paradigm shift are briefly discussed below. T. gondii, feline as the definitive host, is regarded as one of the most important parasites in the tropic. Human, as an accidental host, is the only species who still drinks raw milk or milk products particularly from animal sources. Based on the first paper, the author simplifies on how safe to drink milk to prevent the transmission of T. gondii by the insistence on heat treated milk before consumption. It is interesting to explore how hormone plays its role in Toxoplasma infection. Based on the second paper, the authors elucidated from thirty studies from humans, animals and cell cultures. Of these, it was shown that Toxoplasma infection was controlled by the presence of hormones found in different animal models. However, it is still premature to conclude which hormone that has a significant relationship with Toxoplasma infection. It estimates that one-third of the world population infected with T. gondii but the majority are asymptomatic. Based on the third paper, it demonstrated that people having low prevalent of Toxoplasma infection by having close contact with animals. This study will enhance positive attitudes for more people to be committed towards helping animals. For more than three decades, T. gondii has since been identified as one of the most important opportunistic parasitic pathogens in immunocompromised. Seroprevalence of chronic toxoplasmosis was detected in at least one-third of HIV-infected individuals in the regional hospital of southern Thailand, as reported from the fourth paper. Thailand has successfully formulated anti-retroviral therapy for HIV/AIDS patients and as a result reported a rare incidence of AIDS-related cerebral toxoplasmosis (CT) in this setting. Based on the fifth paper, the authors demonstrated low IL-10 (Th2 response) and IFN-γ (Th1 response) as well as high TNF-α were produced in ocular and cerebral toxoplasmosis in AIDS patients. This might be due to South American strains and/or the genetic susceptibility of the host. Due to high genetic diversity of T. gondii in Brazil, the sixth paper demonstrated that Calomys callosus survived chronically infected by T. gondii clonal type II strain and reinfected by Brazilian strains. However, congenital toxoplasmosis occurred leading to damaging effects of the developing fetus. The seventh paper conducted a questionnaire-based study on knowledge and practice on Toxoplasma infection among pregnant women from Malaysia, Philippines and Thailand. It clearly demonstrated that health education, a core value, is the cheapest and the best option to envisage the preventive strategies of feto-maternal toxoplasmosis from this region. For treatment modality of congenital toxoplasmosis, a novel experimental therapeutic synergism of diclazuril plus atovaquone combination shows a promising outcome with no toxicity in treating this condition, as demonstrated in the eighth paper. However, it warrants for future trials to prove its properties against T. gondii in different clinical scenarios of human toxoplasmosis for more effective therapeutic regimens. In the ninth paper, the author discussed the pathogenesis of maternal and congenital toxoplasmosis, the current treatment in clinical practice, and the experimental treatment approaches for promising future trials. Overall, this protozoan represents the most extraordinary example of parasite in the tropic and beyond scientific imagination. Hence, there are still many challenges ahead and waiting for more explorations on T. gondii, the parasite that never dies. Based on the findings from the tenth paper, it is interesting to identify common gene targets between Glossina p. gambiensis and Glossina m. morsitans that might shed some lights as a suitable candidate for controlling both acute and chronic forms of sleeping sickness. This therefore requires further investigations using proteomic analysis to ascertain the corresponding genes and its proteins as well as functional role that may help the search for more novel therapeutic agents.
Download or read book Tropical Forest Community Ecology written by Walter Carson and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, tropical ecology has been a science often content with descriptive and demographic approaches, which is understandable given the difficulty of studying these ecosystems and the need for basic demographic information. Nonetheless, over the last several years, tropical ecologists have begun to test more sophisticated ecological theory and are now beginning to address a broad array of questions that are of particular importance to tropical systems, and ecology in general. Why are there are so many species in tropical forests and what mechanisms are responsible for the maintenance of that vast species diversity? What factors control species coexistence? Are there common patterns of species abundance and distribution across broad geographic scales? What is the role of trophic interactions in these complex ecosystems? How can these fragile ecosystems be conserved? Containing contributions from some of the world’s leading tropical ecologists, Tropical Forest Community Ecology provides a summary of the key issues in the discipline of tropical ecology: Includes contributions from some of the world’s leading tropical ecologists Covers patterns of species distribution, the maintenance of species diversity, the community ecology of tropical animals, forest regeneration and conservation of tropical ecosystems
Download or read book Conservation of Tropical Birds written by Navjot S. Sodhi and published by John Wiley & Sons. This book was released on 2011-02-23 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.
Download or read book Microbial Role in the Carbon Cycle in Tropical Inland Aquatic Ecosystems written by André Megali Amado and published by Frontiers Media SA. This book was released on 2017-03-15 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 few studies in the tropical area. In the prospective of global changes where the warm tropical lakes and rivers become even warmer, it is important to understand how microorganisms behave and interact with carbon cycle in the Earth region with highest temperature and light availability. This research topic documented microbial responses to natural latitudinal gradients, spatial within and between ecosystems gradients, temporal approaches and temperature and nutrient manipulations in the water and in the sediment.
