Book Description
A paisagem da parte sul do Pantanal é formada por um mosaíco de rios, lagos, brejos, campos úmidos estacionais e florestas que são fortemente influenciados pelos níveis da água no solo. Ao sul do Rio Negro, na região de inundação estacional, desenvolve-se a forma clássica da savana úmida que apresenta como grandes extensões de campo com arbustos e árvores (Curatella americana, Byrsonima orbignyana) os quais são resistentes à inundação.

Book Description
There are many famous wetlands in the world that have been deemed important for the homeostasis ofthe biosphere and accorded some form ofprotected status in view of the richness of their flora and fauna. T}1e Pantanal, located almost directly in the center ofthe South American continent, is among the largest such wetlands in the world. It is, in fact, the largest wetland that is still in a nearly natural state and has not been extensively modified by man for agriculture. The extent of the region covered by flood waters at the end of each rainy season varies from year to year, sometimes considerably, so estimates of the exact area it occupies have varied enormously. The size of the 2 2 Pantanal has been reported to be between 80,000 km (Bonetto, 1975) and 250,000 km (Tundisi and Matsumura-Tundisi, 1985). The most co~on1y accepted estimates at the present time are approximately 130,000 to 140,000 km , supported by estimates made from Nimbus-7 satellite observations (Hamilton et al. , 1996). However, Por (1995) suggested that the area extending into Bolivia and Paraguay has not been satisfactorily 2 surveyed, leading him to accept the figure of 200,000 km as the area of the entire Pantanal, ineluding all of its extensions. The main reason for the year to year variation in the extent of the flooding is the considerable difference in timing of the rainfall on the watershed.

Book Description
Sustainability and the Rights of Nature in Practice is the much-needed complementary volume to Sustainability and the Rights of Nature: An Introduction (CRC Press, May 2017). The first book laid out the international precursors for the Rights of Nature doctrine and described the changes required to create a Rights of Nature framework that supports Nature in a sustainable relationship rather than as an exploited resource. This follow-up work provides practitioners from diverse cultures around the world an opportunity to describe their own projects, successes, and challenges in moving toward a legal personhood for Nature. It includes contributions from Nepal, New Zealand, Canadian Native American cultures, Kiribati, the United States and Scotland, amongst others, by practitioners working on projects that can be integrated into a Rights of Nature framework. The authors also tackle required changes to shift the paradigm, such as thinking of Nature in a sacred manner, reorienting Nature’s rights and human rights, the conceptualization of restoration, and the removal of large-scale energy infrastructure. Curated by experts in the field, this expansive collection of papers will prove invaluable to a wide array of policymakers and administrators, environmental advocates and conservation groups, tribal land managers, and communities seeking to create or maintain a sustainable relationship with Nature. Features: Addresses existing projects that are successfully implementing a Rights of Nature legal framework, including the difference it makes in practice Presents the voices of practitioners not often recognized who are working in innovative ways towards sustainability and the need to grant a voice to Nature in human decision-making Explores new ideas from the insights of a diverse range of cultures on how to grant legal personhood to Nature, restrain damaging human activity, create true sustainability, and glimpse how a Rights of Nature paradigm can work in different societies Details the potential pitfalls to Rights of Nature governance and land use decisions from people doing the work, as well as their solutions Discusses the basic human needs for shelter, food, and community in entirely new ways: in relationship with Nature, rather than in conquest of it

Book Description
The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Book Description
We often envision the New World before the arrival of the Europeans as a land of pristine natural beauty and undisturbed environments. However, David Lentz offers an alternative view by detailing the impact of native cultures on these ecosystems prior to their contact with Europeans. Drawing on a wide range of experts from the fields of paleoclimatology, historical ecology, paleontology, botany, geology, conservation science, and resource management, this book unlocks the secret of how the Western Hemisphere's indigenous inhabitants influenced and transformed their natural environment. A rare combination of collaborators uncovers the changes that took place in North America, Mexico, Central America, the Andes, and Amazonia. Each section of the book has been comprehensively arranged so that a botanical description of the natural vegetation of the region is coupled with a set of case studies outlining local human influences. From modifications of vegetation, to changes in soil, wildlife, microclimate, hydrology, and the land surface itself, this collection addresses one of the great issues of our time: the human modification of the earth.

Book Description
The international journal Ecohydrology & Hydrobiology (E&H) has been created to promote the concept of Ecohydrology, which is defined as the study of the functional interrelations between hydrology and biota at the catchment scale. Ecohydrology extends from the molecular level to catchment-scale processes and is based on three principles: • framework (hydrological principle) - quantification and integration of hydrological and ecological processes at a basin scale; • target (ecological principle) - necessity of enhancing ecosystem absorbing capacity and ecosystem services; and • management tool (ecological engineering) – the use of ecosystem properties for regulation the interplay between hydrology and biota. The journal encourages the submission of manuscripts which adopt an integrative approach to aquatic sciences, explaining ecological and hydrological processes at a river-basin scale or propose practical applications of this knowledge. It will also consider papers in other hydrobiological fields. Especially welcome are papers on regulatory mechanism within biocenosis and the resistance and resilience of freshwater and costal zones ecosystems. There is no page charge for published papers. All submitted papers, written exclusively in English, should be original works, unpublished and not under consideration for publication elsewhere. All papers are peer-reviewed. The following types of papers are considered for publication in E&H: • original research papers • invited or submitted review papers, • short communications

Book Description
With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.
