Book Description
Antarctica's severe climate and restricted area of ice-free habitats limit the biodiversity and biota of its terrestrial ecosystems. Throughout much of this wilderness, lichens are the predominant visible life form, yet relatively few descriptive accounts of Antarctic lichens have been published. Research on these enigmatic organisms is increasing rapidly and there is a growing need for a comprehensive guide to the identification of Antarctic lichen-forming fungi. This volume provides the first modern detailed compilation of their taxonomy, ecology, distribution and relevant published literature. As such, it represents a major contribution to global lichen taxonomy and biogeography. The systematic accounts provide sufficient descriptive information to allow specialists to identify taxa to species level, and are structured so that even non-specialists can use them to identify specimens to at least the generic level.

Book Description
The present book covers diversified contributions addressing the impact of climate change on the Antarctic environment. It covers the reconstruction of environmental changes using different proxies. The chapters focus on the glacial history, glacial geomorphology, sedimentology, and geochemistry of Antarctic region. Furthermore, the Cenozoic evolution of the Antarctic ice sheet is discussed along with a Scientometrics analysis of climate change research. The book serves as a useful reference for researchers who are fascinated by the polar region and environmental research.

Book Description
Understanding the sediments deposited by glaciers or other cold-climate processes assumes enhanced significance in the context of current global warming and the predicted melt and retreat of glaciers and ice sheets. This volume analyses glacial, proglacial and periglacial settings. Papers include topics such as sedimentation at termini of tidewater glaciers, poorly understood high-mountain features, and slope and aeolian deposits that have been sourced in glacial and periglacial regions and subsequently transported and deposited by azonal processes. Difficulties encountered in inferring Pleistocene and pre-Pleistocene cold-climate conditions when the sedimentary record lacks specific diagnostic indicators are discussed. The main objective of this volume is to establish the validity and limitations of the evidence that is used to achieve reliable palaeogeographic and palaeoclimatic reconstructions. On the much longer geological timescale, an understanding of ice-marginal and periglacial environments may better prepare us for the unavoidable reversal towards cooler and perhaps even glacial times in the future.

Book Description
The Revised Second Edition of Flora of New Zealand: Lichens is an updated and definitive guide to the country's rich and diverse lichen flora. This revised identification manual comprises two volumes and supersedes the version published in 1985 and includes for the first time a treatment of lichenicolous fungi, specialist fungal parasites that have co-evolved with lichens. Lichens are fungi that have evolved a specialised mode of nutrition and are primary colonisers. They are common in all New Zealand landscapes, from inner-city footpaths to the summit rocks of Aoraki Mt Cook, and cover surfaces as diverse as rock, tree bark and buildings. Although tolerant of a wide range of ecological conditions lichens are extremely sensitive to atmospheric and terrestrial pollution and have an important use as bio-monitors of environmental health and change. Lichens are important in grassland and forest ecosystems as major nitrogen fixers, acting as biological fertilisers and they have potential value in processes of ecological repair and restoration. Flora of New Zealand: Lichens discusses 1706 taxa in 354 genera. Keys to genera cover foliose, squamulose, fruticose, filamentous, placodioid, leprose, crustose, foliicolous and lichenicolous life forms. All genera have descriptions, and commentaries provide up-to-date references. Species descriptions discuss thalline, apothecial and chemical characters, and a biogeographical grouping is given. All names based on New Zealand material are typified, both homotypic and heterotypic synonyms are listed, and the provenance of type material is indicated when known. An index to accepted taxa and to synonyms is provided plus a bibliography.
