Book Description
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book Description
The Western Ghats forests are endowed with large species and habitat diversity, which is nowadays under threat by increasing demographic pressure and changing land use. To address these challenges, a novel and comprehensive approach is sought from the principles of landscape ecology. Morpho-pedological features are used to delineate landscape units all over the Western Ghats of Kerala, among which the Western Anamalai region is chosen to elucidate the relative influence of physical factors, bioclimate and anthropogenic pressures on the characteristics of natural vegetation and on the status of the vertebrate fauna. Highlighting patterns of resource utilization by proximal and distant stakeholders, the book goes about identifying value-based management zones, while proposing management strategies for conservation and sustainable development.

Book Description
The floods that devastated large parts of Kerala in 2018 were not an isolated, freak phenomenon; rather, they signalled something graver-the ecological devastation of the Western Ghats. Made a UNESCO World Heritage Site in 2012, the Ghats have become increasingly vulnerable to serious ecological damage, threatening the sustenance of their people. The 2018 floods were a wake-up call for the region spanning 1600 kilometres and six states-Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat-that form an ecosystem older than the Himalayas. Travelling in this region, documenting the devastating large-scale mining, quarrying, deforestation and mismanagement of water resources, at the same time mapping its culture, history and ecology, Viju B. investigates the crisis in the Western Ghats and suggests policy measures urgently required to mitigate it.

Book Description
The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.

Book Description
The hill chain of Western Ghats, a treasure trove of biodiversity and the water tower of peninsular India has been engrossed the attention of various stakeholders all over the world. This region is identified as one among the eight hottest hotspots of biodiversity and hence attracted worldwide attention. This book is a compilation of various research articles related to Western Ghats, its ecology, environment, geography, biodiversity, etc. The editors have taken utmost care to include articles related to various issues such as, the debates over WGEEP and HLWG reports, studies on mining and quarrying activities, agriculture and allied activities, issues related to sustainable agricultural practices, agrarian distress, impact of migration, changing land use pattern, other economic activities and its impact on the environment and ecology, etc. The book offers an insight into the concerns of the farmers and offers policy solutions wherever possible.

Book Description
Microbial Diversity in Hotspots provides an introduction to microbial diversity and microbes in different hotspots and threatened areas. The book gives insights on extremophiles, phyllosphere and rhizosphere, covers fungal diversity, conservation and microbial association, focuses on biodiversity acts and policies, and includes cases studies. Microbes explored are from the coldest to the hottest areas of the world. Although hotspots are zones with extremely high microbiology activities, the knowledge of microbial diversity from these areas is very limited, hence this is a welcome addition to existing resources. - Provides an introduction to microbial biotechnology - Addresses novel approaches to the study of microbial diversity in hotspots - Provides the basics, along with advanced information on microbial diversity - Discusses the techniques used to examine microbial diversity with their applications and respective pros and cons for sustainability - Explores the importance of microbial genomes studies in commercial applications
