The book provides a comprehensive account of a tropical lake, Alchichica, considering that tropical limnology is by far less known and well-understood than temperate. Many of the well-known temperate limnology paradigms do not apply in tropical limnology, such as the ≥ 1oC/m thermocline concept, or the role of phosphorous as a limiting nutrient. Lake Alchichica is - most likely – the best limnologically known Mexican lake up to date. Twenty years of continuous monitoring has led us to understand this deep, warm monomictic lake. The peculiar chemical composition of this saline lake – sodium-alkaline with a high concentration in magnesium waters, and groundwater-fed – led to the formation of its unique stromatolite ring that has become world-famous, studied by scientists from various countries. From a biological point of view, this relatively small maar lake displays a comparatively low species richness but surprisingly is plentiful in microendemic species for a recently-formed lake (13,000-6,300 years old, at the Late Pleistocene/Holocene Epoch), eleven of which already described, with more to come. Researchers and students interested in tropical limnology, extreme ecosystems, evolutionary biology, astrobiology, and microbiology will find this book a must-read.

The present volume comprises aspects of both basic and applied limnology. They include works on physical, chemical, and biological limnology, as well as experimental approaches in selected areas. Contributions from investigators regarding aquatic conservation and biodiversity were specifically not available and therefore, these aspects are considered in various included works. Most manuscripts deal with lentic aquatic resources. This is not surprising since Mexican limnology followed the general study trend of that from temperate limnology. Despite this, we must emphasize that lotic resources in Mexico are quite important both locally and regionally. This does not mean that rivers are not under limnological research in Mexico, just that their study has only recently begun. It is the intention of the volume to stimulate a larger section of limnologists to further research in this field. It is to be hoped that policy-framing governmental authorities in Mexico will benefit from it, and consider some of the aspects described so that further damage to the epicontinental waterbodies can be halted, and remedial measures can be considered in the future.

This contributed volume presents an analysis of the current conservation status of major faunal groups in Mexico. The chapters describe a prognosis of future challenges, and also explore the expanding threats inherent in the Anthropocene within the context of the unique physical, biological and cultural aspects of the nation. Covering 27 chapters, and written by Mexican and international authors, this book analyzes a wide range of vertebrate and invertebrate animal taxa, their ecosystems and the critical processes related to their present conservation status. This volume is an important reference material for researchers, conservationists and students interested in the biological and ecological processes shaping the Mexican fauna.

Inland saline waters are threatened worldwide by diversion and pollution of their inflows, introductions of exotic species and economic development of these ecologically valuable habitats. Since 1979 a series of international symposia on inland saline waters has served to strengthen and expand the scope of limnological research on inland saline waters. The seventh conference continued this tradition and the papers derived from the conference focused on the ecology of microbial communities, the influence of habitat geochemistry on biogeography of flora and fauna, physical and geochemical processes, and the conservation of inland saline waters. Of particular note are papers on Walker Lake, Nevada (USA), and the Salton Sea and Mono Lake, California (USA). Continued local, national and international efforts are required to inform the public and decision-makers about the environmental problems faced by saline waters. The papers in this volume will serve this end and should be of interest to aquatic ecologists, limnologists, aquaculturalists, and water resource managers.

Lakes are highly essential for their water quality, habitat suitability, and water supply. Lakes constitute important source for aquatic life, fish, wildlife, and human, but can undergo rapid environmental changes. Most important factors that affect lake ecosystem are climate, atmospheric inputs, land use, morphology, and physiography. Several environmental problems can affect a lake's water quality, and habitat suitability. The book "Lake Sciences and Climate Change" deals with several aspects of lake sciences (botany, zoology, geology, chemistry, models, morphology, and physiography) ,as well as the effect of climatic changes on lake body ecosystem. The book is divided into three sections and structured into 10 chapters. The first section discusses the relationship between lake and climatic change; the second section explains lake biology and health; and the third section focuses on water quality, management, and modeling. Scientists from different fields of lake sciences reported in this book their findings.

Pursuing a multidisciplinary approach, this book highlights current challenges in, and potential solutions to, environmental water management in Mexico. It includes an essential review of current literature and state of the art research, providing a one-stop resource for researchers, graduate students and environmental water managers alike. The result of a cooperation between 35 researchers from seven Mexican academic institutions, two Federal Commissions and one international organization, the book links science to practice for living organisms and their environment, while also addressing anthropogenic effects on our water ecosystems. Particularly the book addresses the following subjects: Biodiversity in inland waters, physical and chemical characterization of inland waters, physico-chemical characterization of Mexican coastal lagoons, microbiota in brackish ecosystems, diversity associated with southern Mexico’s pacific coral reefs, fry fish stockings in aquatic epicontinental systems, a review of tuna fisheries in Mexico, fishery resource management challenges stemming from climate change, aquatic invasive alien species, harmful algal blooms, and aquatic protected areas, related ecological and social problems and the importance for fisheries’ yield.

Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology.Key Features* The first complete accounting of North America's freshwater algal genera in more than 50 years* Includes a guide to the current literature on species identification in each group of algae* High-quality photographs and drawings of more than 770 genera* A clear, easy-to-use introductory key to the diagnostic chapters* Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae* Contributions from 27 experts in all areas of freshwater algae* Extensive literature citations* Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich
