Algal species and in particular desmids are important indicators of water quality. Because of their preferential occurrence in vulnerable habitats, desmids lend themselves well to figuring in conservation studies. The present flora describes all desmid taxa known from the Netherlands and adjacent lowland areas: over 500 species and more than 150 additional varieties. Because of the predominantly cosmopolitan nature of most species the flora may also be of use outside this geographic region. The enclosed CD-ROM offers general information on desmid biology as well as a selection of species that are discussed in more detail. Ecological data, both on separate species and desmid communities, enable a characterization of the habitat sampled.

Основная идея этой книги – показать таксономическое значение топографии клеточной стенки на примере видов из рода Euastrum. В книге приведены результаты изучения рода Euastrum, одного из наиболее разнообразных родов десмидиевых водорослей. В общей сложности более 2000 клеток 45 видов Euastrum были исследованы с помощью сканирующего электронного микроскопа (СЭМ). Богатый видовой состав флоры Европы, большое количество образцов и более чем 10-летние исследования позволили увидеть и проанализировать распространение и взаимосвязь скробикул, бородавок, слизистых пор и традиционных морфологических признаков. Включение в список видов, рельеф оболочки которых еще не изучен, демонстрирует область будущих исследований в этом направлении. Объединение видов в группы в зависимости от наличия скробикул того или иного типа, а также в группы безскробикульных видов, я надеюсь, позволит коллегам в будущем более легко выявлять и описывать новые таксоны, а также обращать внимание на значимые признаки.Во Введении приведено описание строения клетки Euastrum и основных структур, которые будут рассмотрены в систематической части. В Методической части описаны материалы, на основе которых проведено исследование, подробно объяснено, как изготавливать препараты для сканирующего электронного микроскопа, дан аннотированный перечень используемых терминов. В начале Систематической части подробно описан рельеф клеточной стенки, сходства и различия в строении клеток разных видов Euastrum. Впервые более 40 видов были подвергнуты исследованию в СЭМ, кроме того, были обобщены данные по всем существующим в настоящее время Euastrum (74 вида) из Европы. Всего представлено 47 таблиц с фотографиями в СЭМ структур поверхности клеточной стенки. В связи с тем, что исследование клеточных покровов проведено на образцах водорослей, собранных в водоемах России, приведены данные о распространении видов в регионах европейской части России. Распространение видов в Европе (с указанием стран) и в мире (с указанием континентов) приведено в описании таксонов. Список использованной литературы включает основные аннотации исследований видов рода Euastrum в Европе, в том числе публикации, в которых есть микрофотографии СЭМ.После покупки предоставляется дополнительная возможность скачать книгу в формате epub.

This flora represents the European species of het desmid genera Staurastrum and Staurodesmus and contains reliable identification keys and general information on the morphology, taxonomy, ecology and geographical distribution. An invaluable tool for aquatic ecologists and water quality management. The desmid genera Staurastrum and Staurodesmus are notorious for their confusing taxonomy and problematic species identification. To a large part this is due to a lack of reliable identification manuals. The present flora, dealing with the European species of these genera, aims to meet this need. As well as general information on the morphology and taxonomy of the genera, identification keys to the species are provided. The discussion of each species includes morphological characteristics, ecology and geographical distribution (also beyond Europe). As compared to other desmid genera, a large part of the Staurastrum and Staurodesmus species have a euplanktonic way of life. Reliable identification and knowledge of their ecological demands is most important for the assessment of water quality. Many species have a confined geographical distribution, even within Europe. Shifting distribution patterns of those species might be linked to climate change.

Chironomidae Larvae of the Netherlands and Adjacent Lowlands Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. The subfamily Orthocladiinae is well represented in flowing water. This books contains information about their life cycle, feeding behaviour and their response to environmental factors. Chironomidae Larvae, Vol. 3: Orthocladiinae presents a wealth of information for scientific and practical purpose. The subfamily Orthocladiinae is especially well represented in flowing water. Most of the species need a good supply of oxygen and few larvae are bottom dwellers. Many species emerge early in spring and may be scarce in summer. Other species live in stagnant and even temporary water bodies. • information about the life cycle and feeding behaviour of the larvae and their response to environmental factors such as oxygen conditions, current velocity and saprobity • special attention to the interrelations between these factors • general and specific aspects of the systematics, biology and ecology the genera and species • nomenclature and identification An invaluable tool for aquatic ecologists and water quality management.

Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. This book is an invaluable tool for aquatic ecologists and water quality management covering the most important tribes Chironomini and Pseudochironomini. It presents a wealth of information for professionals for scientific and practical purpose. The Chironomini larvae are the well-known red bloodworms. They are the most important group of the Chironomidae family in stagnant water and can be very numerous, especially in polluted water. Many species are detritus feeders and play a part in the decomposition of organic material. Most species live in a tube of small particles, attached to the substrate. The author has brought together a wealth of information on the biology and ecology of this group geared especially to water quality assessment. This collected knowledge is required in the interpretation of macro-invertebrate samples. An introduction gives background information on the influence of environmental factors on chironomid larvae. A unique focus on this ecologically important group, useful for professionals and especially important for its potential use in water quality management.

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.
