陸水学に関する一冊です。海洋に対し内陸の湖沼などを対象にしていますが、湖といっても南極にもあれば熱帯にもあり、その形、大きさ、深さ、色、また塩分濃度までさまざまです。湖は大きく深いものも多く、人は食料や飲用水の供給源として湖を活用していますが、これは湖の生態系にどのような影響を与えているのでしょうか。DNAを用いた最新の調査法なども交えながら、気候変動を映し出す鏡としての湖の重要性や、生物の棲み処でもある湖の保護を訴えます。
From the mysterious depths of Lake Vostok, Antarctica, to tropical floodplain lakes, inland seas, hydro-reservoirs and the variety of waterbodies in our local environment, lakes encompass a huge diversity of shapes, sizes, depths, colours, and even salinities. Often very large and very deep, they sustain important and unique ecosystems which can be hotspots of biodiversity, and are used by humans as sources of drinking water and food, in particular, fish. What is the origin of differences among lakes, and how does that affect the life within them? What are the seasons of a lake, and how do human actions alter lake ecosystems locally, and at a global scale?
In this Very Short Introductions, Warwick Vincent outlines the essential features of lake environments and their biology, offering an up-to-date view of lake ecosystems. Vincent traces the origins of lake science (limnology) from the seminal work of François Forel on Lake Geneva at the edge of the Swiss Alps, to modern approaches such as environmental sensors, satellite observations, stable isotope analysis, and DNA-based technologies which are used to probe the microbial life support systems that lead from sunlight to fish. Drawing on varied case studies he considers the intimate relationship between humans and lakes, the value of lakes as indicators of environmental change, the impact of pollution,and our urgent need to improve the protection and management of these vitally important living resources via an integrated understanding of their ecology.

Index
"A fast-track insight into lakes, from how they're formed to a hit list of 'extreme lakes' in unusual places. Packed with facts but not (ahem) a dry read." - Sarah Barrell, National Geographic Traveller
"Does an excellent job at showing how biology, chemistry and physics are inextricably linked and necessary to understand lakes. Overall, this short book provides an excellent and lucid introduction to the beauty and complexity of lakes." - Yves Prairie, UNESCO Chair in Global Environmental Change
"This book is a sparkling gem! It is a must-read not only for novices intrigued by freshwaters but also academics teaching limnology (study of inland waters) and university students interested in the subject." - Marianne Moore, Frost Professor Emerita in Environmental Science, Wellesley College.
