Antarctic Peninsula & Tierra del Fuego: 100 years of Swedish-Argentine scientific cooperation at the end of the world
This symposium, held in Argentina in March 2003, commemorates Otto Nordenskjöld’s 1901 expedition, and pays tribute to the Swedish and Argentinian explorers who took on the challenge of early fieldwork in Patagonia and Antarctica. This theme is extended to include recent fieldwork in the natural sciences in the Archipelago of Tierra del Fuego, the Antarctic Peninsula and the sub-Antarctic seas, and celebrates the fruitfulness of continuing Swedish-Argentinian scientific cooperation. The symposium and associated activities took place in the cities of Buenos Aires, La Plata and Ushuaia (Tierra del Fuego), and this book includes a selection of the most significant contributions presented at the meeting.
Illustrated Moss Flora of Antarctica
Mosses are a major component of the vegetation in ice-free coastal regions of Antarctica. They play an important role in the colonisation of ice-free terrain, accumulation of organic matter, release of organic exudates, and also provide a food and habitat resource for invertebrates. They serve as model organisms for physiological experiments designed to elucidate problems of plant cold tolerance and survival mechanisms and for monitoring biological responses to climate change. This Flora provides the first comprehensive description, with keys, of all known species and varieties of moss in the Antarctic biome. It has involved microscopic examination of around 10,000 specimens from Antarctica and, for comparison, from other continents. All species are illustrated by detailed line drawings, alongside information about their reproductive status, ecology, and distribution. This is an invaluable resource for bryologists worldwide, as well as to Antarctic botanists and other terrestrial biologists.
Plants of Oceanic Islands
This book provides a comprehensive view of the origin and evolution of the plants of an entire oceanic archipelago.
Environmental History of Oceanic Islands
The Juan Fernández Archipelago is located in the Pacific Ocean west of Chile at 33° S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation. The older island has undergone more substantial changes, due to both natural causes and human impacts. After the discovery of Robinson Crusoe Island in 1574, people began cutting down forests for lumber to construct boats and homes, for firewood, and to make room for pastures. Domesticated plants and animals were introduced, some of which have since become feral or invasive, causing damage to the local vegetation. The wealth of historical records on these activities provides a detailed chronicle of how human beings use their environment for survival in a new ecosystem. This book offers an excellent case study on the impacts that people can have on the resources of an oceanic island.
Plant Geography of Chile
The first and so far only Plant Geography of Chile was written about 100 years ago, since when many things have changed: plants have been renamed and reclassified; taxonomy and systematics have experienced deep changes as have biology, geography, and biogeography. The time is therefore ripe for a new look at Chile’s plants and their distribution. Focusing on three key issues – botany/systematics, geography and biogeographical analysis – this book presents a thoroughly updated synthesis both of Chilean plant geography and of the different approaches to studying it. Because of its range – from the neotropics to the temperate sub-Antarctic – Chile’s flora provides a critical insight into evolutionary patterns, particularly in relation to the distribution along the latitudinal profiles and the global geographical relationships of the country’s genera. The consequences of these relations for the evolution of the Chilean Flora are discussed. This book will provide a valuable resource for both graduate students and researchers in botany, plant taxonomy and systematics, biogeography, evolutionary biology and plant conservation.
Polynesians in America
The possibility that Polynesian seafarers made landfall and interacted with the native people of the New World before Columbus has been the topic of academic discussion for well over a century, although American archaeologists have considered the idea verboten since the 1970s. Fresh discoveries made with the aid of new technologies along with re-evaluation of longstanding but often-ignored evidence provide a stronger case than ever before for multiple prehistoric Polynesian landfalls. This book reviews the debate, evaluates theoretical trends that have discouraged consideration of trans-oceanic contacts, summarizes the historic evidence and supplements it with recent archaeological, linguist...
Hoosh
Antarctica, the last place on Earth, is not famous for its cuisine. Yet it is famous for stories of heroic expeditions in which hunger was the one spice everyone carried. At the dawn of Antarctic cuisine, cooks improvised under inconceivable hardships, castaways ate seal blubber and penguin breasts while fantasizing about illustrious feasts, and men seeking the South Pole stretched their rations to the breaking point. Today, Antarctica’s kitchens still wait for provisions at the far end of the planet’s longest supply chain. Scientific research stations serve up cafeteria fare that often offers more sustenance than style. Jason C. Anthony, a veteran of eight seasons in the U.S. Antarctic ...
Antarctica
Antarctica, a vast land remote from the other continents and still the least known of them all, provides a unique international laboratory for science. Despite the costs, a growing number of countries are supporting basic scientific research on the continent and in its surrounding seas. Our knowledge of life in this extreme environment, although limited, suggests that it is a key environment for many areas of science. Potential economic developments for food and minerals as well as increasing political complications might jeopardise the present scientific accord in the future. Now is the time to take stock: what do we know about Antarctic ecology? What are the threats and how can they be met? In this volume Antarctic scientists from six countries write about the Antarctic ecosystem.
