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, colors, 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 Francois 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.

Bradt's Alentejo remains the only standalone guide to this emerging region, providing all the information needed to find that idyllic rural retreat, beachside boutique or romantic hotel set in a converted palace. Restaurants, wines, cafes and cultural sights have all been meticulously chosen and reviewed by the author and there is a wealth of background cultural and historical information to unlock the secrets of the Alentejo's colourful past and captivating present.This new second edition has been thoroughly updated to reflect all the most recent developments and includes a new section on castle towns, expanded information on Alandroal and Juromenha, new coverage of Alegrete and the Serra de Sao Mamede and new features on everything from The Siege of Badajoz to Alentejo wild flowers, Portuguese grape varieties and the Rebel Prince of Marvão amongst others. More hotels and tours have also been added, especially around Évora, Monsaraz and Marvão.The Alentejo is Portugal's Andalusia – without the crowds – a landscape littered with Moorish monuments, sleepy villages and Crusader castles. The beaches are glorious sweeps of white sand, broken by rocky coves nested by storks, or backed by caramel coloured sandstone cliffs. The towns and villages of the interior appear little-changed since medieval times – clusters of sugar-cube houses tumble down hills from heavy-set castles. There are palaces and there are myriad megalithic monuments – lost in the rolling countryside in the olive groves, or among orange trees and withered cork oaks. Wild boar and lynx roam the extensive forests and heathlands – which offer wonderful hiking and hill walking. And the food… fresh Atlantic bream, sizzling prawns, forest-reared pork and dozens of glorious wines with which to wash it down.Expert author and fluent Portuguese speaker Alex Robinson has been visiting, writing and photographing Portugal for more than 20 years and in this new edition has evolved his guide to the Alentejo even further to make an ideal companion for a successful trip whatever your interest, age or budget: hikers, wine and food lovers, weekend travellers, history enthusiasts and those looking for a second home are all catered for.
