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.

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.

The Netherlands are a small country, characterized by a large diversity of fresh to slightly brackish, oligo- to hypereutrophic stagnant and flowing inland waters. This diversity is reflected in a remarkable richness of phytoplankton species with blue-green algae as an important component. Identification of phytoplankton frequently brings on serious problems, due to the scarcity of up-to-date floras. This book, written by an acknowledged Dutch phytoplankton expert, presents a new modern approach to the identification of phytoplankton of The Netherlands. • treats 95 species belonging to 23 genera of non-filamentous blue-green algae in the plankton of Dutch inland waters including one new genus and 15 new species • nomenclature according to modern insights and in agreement with international rules • 500 original black-and-white photographs show all the details necessary for light-microscopical identification • contains an identification key to the species and comparing every species to similar forms • information on ecology and occurrence in different water types • relevant literature references

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.

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.

A 2014 Choice Magazine "Outstanding Academic Title" An Atlas of the World's Conifers is the first ever atlas of all known conifer species. It is based on locality information of ca. 37,000 collected herbarium specimens held in scientific institutions. As well as providing natural distribution maps for each species, Farjon and Filer give the reader comprehensive insight into the biogeography, diversity and conservation status of conifers on all continents, dispelling the widely held view that they are primarily a northern boreal plant group. Conifer diversity is analysed and presented with a taxonomic and geographic perspective. Distribution patterns are interpreted using the latest information on continental drift, dispersal and phylogeny. The entire dataset supporting the Atlas can be consulted and verified online. These data can also be used for further research and are an invaluable resource for anyone working on conifer systematics, biogeography or conservation. An Atlas of the World’s Conifers indicates the known distribution of all conifers including an analysis of their biogeography, diversity and conservation status. Also available from Brill is Aljos Farjon’s A Handbook of the World's Conifers, published in 2010 (ISBN 978 90 04 17718 5) which is a 2017 Choice Magazine "Outstanding Academic Title".
