The remote mountain loch of Lochnagar is one of the most studied freshwater bodies in Europe. This book brings together knowledge gained over two decades of multi-disciplinary scientific study, with the results of lake sediment research covering millennia, to show how the loch has developed both naturally and as a result of human impact. Particular emphasis is placed on how this fragile ecosystem, and others like it, may be affected by future climate change.

Chrysophycean algae are a diverse and often abundant group of primarily freshwater phytoplankton, characterized by the endogenous formation of siliceous cysts or stomatocysts (also called statospores or statocysts). Cyst morphology is highly variable, but believed to be species-specific. Recently, cysts have received considerable attention from phycologists and especially paleoecologists who wish to use these indicators for assessments of environmental change. Nonetheless, attempts at using cysts have often been hampered by taxonomic problems. This Atlas dispels some of the mystery surrounding stomatocysts, facilitating the accurate identification of individual cyst morphotypes, and encouraging other workers to begin using these important indicators. The terminology used to describe cysts is outlined in detail, followed by detailed descriptions of cyst morphotypes, following International Statospore Working Group (ISWG) guidelines, complemented by scanning electron and light micrographs, as well as line illustrations. Any available biogeographical and ecological information is also provided. These descriptions will further accelerate the continued effort to link cyst morphotypes to the algae that produce them. For paleoecologists who wish to include stomatocysts in their studies, researchers working with living chrysophycean algae, and those interested in the morphology and ultrastructure of cyst morphotypes.

Des del principi dels anys seixanta fins a l’actualitat, el litoral ha estat i és un camp destacat de recerca, en el qual fou pioner entre nosaltres, i on és reconegut, Vicenç M. Rosselló i Verger, professor emèrit de la Universitat de València. Amb motiu de la seua jubilació, un qualificat grup de noranta científics, especialment geomorfòlegs, li reten homenatge amb aquest llibre per la modèlica tasca investigadora desplegada des de la càtedra i per l’impuls atorgat a l’estudi geomorfològic de les costes, especialment les de la mar Balear. Al llarg de la seua carrera universitària, Rosselló ha fet de l’orla maritimoterrestre un eix fecund i vertebrador d’una part significativa de la seua recerca, mostrant les complexes interaccions de natura i cultura. No debades, les costes del professor Rosselló són ancoratges de la transició ecològica entre la terra ferma i la mar oberta, morfologies resultants de precaris equilibris i una clau explicativa de la dinàmica d’uns paisatges litorals cada vegada més modelats pels impactes de les societats humanes. Però a més, també ha considerat el litoral com un destacat tret territorial, una frontera històrica, un patrimoni fràgil i escàs, un valor econòmic i simbòlic o un àmbit cartografiat amb diversos estrats toponímics. Aquesta doble perspectiva li ha permès explicar la diversitat, les limitacions, les variacions espacials i els registres temporals, els usos i els abusos concurrents a l’orla costanera mediterrània. El professor Rosselló pertany al reduït grup de mestres universitaris que mantenen una perspectiva il·lustrada de la ciència, allunyats de la creixent segmentació i el replegament de les disciplines acadèmiques i preocupats per comprendre el món. Aquesta cultura universitària –feta de raons, dubtes i sabers, de treball i de compromís, de pensament crític i autocrític– els ha exigit una intensa dedicació a la càtedra, constant atenció als deixebles i obertura a l’entorn. Uns ingredients aquests que defineixen el seu mestratge, des del qual ha tractat d’interpretar el món, practicant una geografia unitària, sense desatendre camps temàtics d’especialització.

This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

This third volume in the Developments in Paleoenvironmental Research series deals with the major terrestrial, algal, and siliceous indicators used in paleolimnology. Other volumes deal with the acquisition and archiving of lake sediment cores, chronological techniques, and large-scale basin analysis methods (Volume 1), physical and geochemical parameters and methods (Volume 2), zoological techniques (Volume 4), and statistical and data handling methods (Volume 5). These monographs will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments.

This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.

This handbook provides a resource for those already familiar with some kinds of micro-particles who wish to learn more about others, or for those just starting out in the study of microremains who wish to have a broad understanding about microscopic archaeology. Topics covered in this handbook include diatom microfossils, starch granules, pollen grains, phytoliths, natural fibers, volcanic glass, minerals, insect remains, and feathers. Archaeological investigations increasingly rely on specialist identification of microscopic remnants found in sites. These micro-particles can provide information about the site environment and human activities that may not be apparent from artifacts and materials preserved on the macro-scale, and have given us new, and often high-profile, information about our past. The investigation of this "invisible archaeology" - that is, invisible to the naked eye - is still somewhat new, and generally each kind of micro-particle is studied individually. Researchers become experts in a narrow range of micro-particle types, but may be less familiar with, or even completely unaware of, the multitude of other forms that are frequently encountered in archaeological samples. This handbook’s accessible approach is suitable for those at the beginner level.
