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 lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices usedto ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.

This book presents contributions from leading international experts in the field of nephrology. Each chapter is independent and discusses nephrology in the author¿s country, including the history of nephrology development, kidney disease epidemiology, clinical nephrology, dialysis practice in acute and chronic renal failure settings (hemodialysis, hemodiafiltration, peritoneal dialysis), pediatric nephrology, and kidney transplantation. In addition, the book covers topics such as the job market for nephrologists, reimbursement, nephrology education, and the number of professionals in the private and public sectors. With 53 chapters and more than 300 authors from all continents offering a unique perspective on nephrology practice, it provides a much-needed information source for nephrologists around the globe. The reader will be able to travel through ¿Nephrology Worldwide¿, a pleasant reading experience with not only relevant information and updated data, but also a comprehensive look at the history, countries¿ peculiarities, and a critical analysis of the scenario of nephrology and renal replacement therapy. A valuable resource for healthcare professionals and other stakeholders interested in learning about the status quo of Nephrology Worldwide. ¿Both the failings and the successes are outlined in a way that should make this book a compelling read, not just for the well-informed renal physician, but also for planners and policy makers whose thinking and actions are integral to the way we practice medicine.¿ - Sir Peter J. Ratcliffe, Nephrologist and 2019 Nobel Prize WinnerMore information on the Nephrology Worldwide initiative can be found at www.nephrologyworldwide.com.

As demonstrated in several of the chapters, these parasites are characterized by peculiar structures and organelles that cannot be found in mammalian cells - even though both are eukaryotic.The book employs light and electron microscopy to display the changing morphology in various stages of parasitic development.

This book brings together twelve original contributions by leading scholars on the much-debated issues of what is free will and how can we exercise it in a world governed by laws of nature. Which conception of laws of nature best fits with how we conceive of free will? And which constraints does our conception of the laws of nature place on how we think of free will? The metaphysics of causation and the metaphysics of dispositions are also explored in this edited volume, in relation to whether they may or may not be game-changers in how we think about both free will and the laws of nature. The volume presents the views of a range of international experts on these issues, and aims at providing the reader with novel approaches to a core problem in philosophy. The target audience is composed by academics and scholars who are interested in an original and contemporary approach to these long-debated issues.Chapters [2] and [4] are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

As the world negotiates immense loss and questions of how to memorialize, the contributions in this volume evaluate the role of culture as a means to promote reconciliation, either between formerly warring parties, perpetrators and survivors, governments and communities, or within the self.

This compendium showcases the ongoing trends and challenges in South-South cooperation between India and select countries in Africa, for achieving food security and poverty reduction.

In fact, even though Galenism was gradually dismissed as a system, several of his ideas spread through the modern world and left their mark on natural philosophy, rational theology, teleology, physiology, biology, botany, and the philosophy of medicine.

This edited collection casts light on central issues within contemporary philosophy of mathematics such as the realism/anti-realism dispute;

This is the fourth volume of Models of the History of Philosophy, a collaborative work on the history of the history of philosophy dating from the Renaissance to the end of the nineteenth century.

This volume is the last (IV) of four under the main themes of Digitizing Agriculture and Information and Communication Technologies (ICT). The four volumes cover rapidly developing processes including Sensors (I), Data (II), Decision (III), and Actions (IV). Volumes are related to ΓÇÿdigital transformationΓÇ¥ within agricultural production and provision systems, and in the context of Smart Farming Technology and Knowledge-based Agriculture. Content spans broadly from data mining and visualization to big data analytics and decision making, alongside with the sustainability aspects stemming from the digital transformation of farming. The four volumes comprise the outcome of the 12th EFITA Congress, also incorporating chapters that originated from select presentations of the Congress. The focus in this volume is on the directions of Agriculture 4.0 which incorporates the transition to a new era of action in the Agricultural sector, represented by the evolution of digital technologies in 4 aspects: Big Data, Open Data, Internet of Things (IoT), and Cloud Computing. Under the heading of ΓÇ£Action,ΓÇ¥ 14 Chapters investigate the implementation of cutting-edge technologies on real world applications.  It will become apparent to the reader that the penetration of ICT in agriculture can result in several benefits related to the sustainability of the sector and to yield the maximum benefits, successful management is required. The entire discussion highlights the importance of proper education in the adoption of innovative technologies starting with the adaption of educational systems to the new era and moving to the familiarization of farmers to the new technologies.This book covers topics that relate to the digital transformation of farming. It provides examples and case studies of this transformation from around the world, examines the process of diffusion of digital technologies, and assesses the current and future sustainability aspects of digital agriculture. More specifically, it deals with issues such as: Challenges and opportunities from the transition to Agriculture 4.0Safety and health in agricultural work automationThe role of digital farming on regional-spatial planningThe enrollment of Social Media in IoT-based agricultureThe role of education in digital agricultureReal-life implementation cases of smart agriculture around the world
