This volume presents the synopsis and revision of LUTICOLA D. Mann, and contains taxa that possess a single stigma, uniseriate striae, round to elliptical areolae and marginal channel along the valve face/mantle junction, internally occluded by hymenes, as well as inwardly strongly thickened central nodule. Additionally one new genus LUTICOLOPSIS has been described. The synopsis covers species from all continents and climatic zones. Special attention was put on species from Central and South America, Antarctica, and the Sub - Antarctic islands. Observations from other localities in Africa, Asia and Australia are included, if samples were available. Around 200 taxa have been observed, one new genus and 92 species are described as new to science. Of these, 91 belong to the genus LUTICOLA and one belongs to the genus LUTICOLOPSIS. A provisional 'key' is presented. The key is not in the conventional form, but it contains 18 tables with the main morphological data and 18 plates with 1 - 3 specimens of all the taxa observed within the study. This unusual key is a product of many discussions with students about the use and benefit of conventional keys. The final score of these discussions was that students want a quick and easier access to information. The provided key hopefully will be useful and user friendly for many 'modern' researchers. The authors point out, that all three of them prefer traditional (conventional) keys instead of tables and plates.

John, Jacob: A Diatom Prediction Model and Classification for Urban Streams from Perth, Western Australia. 2012. 76 plates. 166 p. 4to. Hardcover. (ISBN 978-3-87429-430-0)

Abstract: The metropolitan city of Perth has its beginning with the establishment of the Swan River Colony in 1829, around the Swan-Canning River estuary. Within the last 183 years the city has expanded with almost 1.4 million people inhabiting the metropolitan city impacting heavily on the ecology of the River system. Several natural streams discharging into the system have been drastically modified by intense urbanisation. The River system and its tributaries, streams and drains have been the recipients of nutrients, effluents, and waste water from the urban and rural catchments resulting in severe symptoms of eutrophication over the past several decades. While the rural catchments have been implicated in the eutrophication and pollution of the estuary, the contribution of urban catchments to the degradation of the system is relatively less known. Through urban catchment groups, and the Integrated Catchment Management Policy, the importance of urban streams and drains is just beginning to be recognised. The current project was aimed at developing a predictive model for biomonitoring the urban streams using diatoms as tools. The investigation lasting from 1996 to 1999 focussed on classification of the urban streams using water quality parameters and 'stream conditions' and subsequent development of a predictive model using diatoms as biomonitors. Close to 180 sites were sampled in summer 1996, spring-summer 1997 and autumn-winter 1997 recording as many as 30 environmental variables. These sites represented most of the streams and drains (including 'concrete') in the urban and semi-rural areas of Perth. The sampling sites were established after analyzing the historical data on water quality and catchment conditions, as well as from preliminary observations. A large number of 'reference sites' or 'relatively pristine sites' were required for the model. The semi-rural sites provided the best examples of reference sites, as they were least impacted by urbanisation. Diatom samples from both reference and impacted sites were collected using an artificial sampling device the JJ Periphytometer. All sites were classified on the basis of seven environmental variables, with the highest correlation coefficient with the sites. Agglomerative hierarchical fusion method with flexible unweighted pair group mean averages (UPGMA) within the multivariate pattern analysis program PATN was used. However, currently, PRIMER SOFTWARE (Plymouth Routine In Mutivariate Ecological Research) is considered to be a more efficient multivariate program. The dendrogram with the sites clustered according to their similarity was further analysed and the status of some of the sites revised, recognising a third group'the Intermediates'. Out of more than 208 species of diatoms recorded from the sampling sites, 57 species selected on the basis of their relative frequencies, were used for the classification of the sites to show the similarity in the distribution pattern of diatoms. Diatom assemblages with similar ecological preferences were clustered together. Discriminant function analysis showed that there was a high degree of concordance between the two classifications. Multi- dimensional Scaling (MDS) was employed for ordination of sites based on diatom assemblages. Environmental variables were ...

The study of diatoms has become more relevant today than before. Climate change, global warming, and water crisis impact upon aquatic biodiversity. Diatoms, one of the most ubiquitous aquatic life forms have emerged as the focus of attention as the most sensitive organisms responding to environmental changes. It is only in recent years that the diatom flora of vast inland aquatic systems of remote countries is being explored. While there is a rejuvenated interest in regional diatom floras, there is an acute shortage of introductory publications available for beginners. There are environmental consultants, high school and university students, teachers, researchers in many parts of the world who are interested in diatoms. Jacob John (Australia) has written an introductory book on diatoms, drawn from his extensive experience as a university teacher, researcher and environmental consultant. Prof John has conducted diatom workshops in Australia, Asia and Europe, using parts of this book. The intricate pattern composed of silicon the most abundant element on this planet only second to carbon, makes diatoms attractive to architects and artists alike. This book (150 pages) is amply illustrated by more than 155 Scanning Electron Micrographs and more than 150 Light Micrographs arranged in 77 plates. It is written in a direct and simple style and explains the most commonly used technical terms in diatom studies. A beginners guide to diatoms aims at providing the fundamental characteristics of most common genera with examples of species within each genus.

Abstract:In numerous aspects Lake Baikal is the world most splendid lake of the whole world, just to mention, it is the deepest lake and contains the worlds largest volume of surface freshwater. Located in the so called Baikal Lake rift zone the basin is filled with the thick sedimentary sequence. The origin of the rift zone began over 30 million years BP in the Oligocene. Baikal represents a group of ancient lakes which extends back with their geological history to the Tertiary. Examples of such lakes include also Biva in Japan and Ohrid in Macedonia, East African rift valley lakes including Lake Victoria, Tanganyika and Titicaca in South America. Ancient lakes attract the attention of evolutionists and taxonomists as water bodies hosting a wealth of interesting plant and animals species. It has already been observed in the early years of studies on plant and animals communities and on diatom assemblages in particular that taxa at different rank are restricted in their distribution (endemic) either to ancient lakes themselves or to their close surrounding area. In the forwarded monograph we provide description and illustrate in LM and SEM numerous diatoms. Most significant achievement of our study is that we describe as new for science over 200 species and illustrate over 170 entities which potentially are new for science. It is noteworthy that in this monograph we describe and illustrated taxa representing just 27 genera. In this book we present the highlights of benthic pennate diatom taxa which inhabit just a small piece of the Lake Baikal surface bottom sediments. The major aim of this monograph is to document the biodiversity of the Lake Baikal diatom assemblages. The Lake has turned out to be so rich in species number that we can easily plan the next volume only just to provide the diatomologists with the diversity of the Lake Baikal pennate diatoms and the samples accessible for our examination are just like a tip of the needle when compared to the study area size. The most remarkable observation is that, although Lake Baikal is an ancient lake located in Siberia, a part of the Holarctic, the species composition of its benthic diatom assemblages is fairly different from any other regions of this realm. Without any doubt our research on diatom assemblages supports the hypothesis of Lake Baikal being an evolutionary hotspot. Numerous diatom genera which neither on European nor on the global scale never reach such diversity as it is observed in the Baikal. Results of our study support a hypothesis that diatom assemblages of the Baikal Diatom shallow areas are composed of numerous taxa, either common or rare, which have much broader distributed in the Holarctic realm beingApparently less numerous are taxa considered as Baikal endemics. Surprisingly the species of the deep water appear to be endemic form. They are almost entirely missing even in neighboring regions including northern Mongolia (Lake Hövsgöl), as documented in our own research.

Catalogue of Irish Seaweeds to be published soon (July 2012)

Guiry, Michael D.: A Catalogue of Irish Seaweeds. 2012. Approx. 150 p. gr8vo. Hardcover.

Price: EUR 49.00

An updated systematic catalogue of the seaweeds of the island of Ireland is presented with sources,habitats, distributions, and notes on nomenclature, taxonomy and distribution. Includedare 570 species: 303 species of Rhodophyta, 93 species of Chlorophyta, 13 species of Vaucheria, and 161 species of Phaeophyceae. Three phyla (Rhodophyta, Chlorophyta, and Ochrophyta), 11 classes (5 Rhodophyta; 4 Chlorophyta; 2 Ochrophyta), 35 orders (19 Rhodophyta; 5 Chlorophyta; 11 Ochrophyta), 90 families (50 Rhodophyta; 16 Chlorophyta; 24 Ochrophyta) are represented. English and Irish vernacular names, and sources for these are given, together with a glossary of Irish names. A list of seaweeds found in Britain but not reported from Ireland to date is given together with distributional, taxonomic, nomenclatural, and other details. A preliminary comparative conservation assessment of 334 species of rare or potentially rare species in Britain and Ireland is given in tabular form. Two new names are included: Rhodophyllis irvineorum M.D.Guiry, C.A.Maggs & F.StP.D.Bunker (Gigartinales, Rhodophyta), and Schmitziellaceae, M.D.Guiry fam. nov. (Gigartinales, Rhodophyta). Seventy-six species are known from Britain (including two varieties of species not otherwise known to occur in Britain), but not from Ireland: 53 reds, 14 greens, a single Vaucheria, and 28 browns. Twenty of these (18 reds and two browns) are considered to be adventive or potentially adventive, leaving only 76 native species that are found in Britain but not in Ireland, which results in an Irish seaweed flora that is currently about 88% of the native British seaweed flora, contrasting very favourably with a native flowering-plant flora in Ireland of about 50% of that of Britain (approximately 850 vs 1700 species). Worldwide, there are about 9500 species of seaweeds (6200 reds; 1500 greens; 1800 browns). Thus, about 7.5% of the worlds known seaweeds occur in Ireland, which is considerable given its geographical location and range, and its relatively narrow temperature ranges and subtidal light penetration. By contrast, the native Irish flowering plant flora is, at most, 0.25% of the world's 350-400,000 flowering plant species.

In recent times there have been many books to illustrate in color the Worlds plant diversity. They mostly present showy flowers such as ornamentals, orchids in particular. The idea of devoting an entire volume of pictures to humble grasses is novel. Grasses are among the most important families for human kind, and knowing them is of considerable practical value. However, they are reputed to be hard to identify, all looking the same. This is not a popular book but part of an important national Flora of high scientific standing. The panicoid grasses dealt with in the accompanying text volume (with descriptions, keys, full synonymies, distribution maps and other important data, as usual) are the familys largest and most difficult group, accounting for more than half of Cubas Poaceae species: 266 in total. Some are endemic to Cuba, but over 80 are of foreign origin and naturalized, often important as forage grasses and/or noxious weeds. All native and naturalized taxa, 250 in total, are represented photographically, each on two facing pages showing the general habit (representative herbarium specimens, mostly Cuban, often types) and at least one close-up of a spikelet or spikelet group, shown under a stereo-microscope equipped with extended focus imaging (a novel technique that allows merging images taken at various focal levels into a single picture). They are an ideal complement to the keys and descriptions of the text, convenient for consultation side by side as text and illustrations are separately bound.

Price: 79.00

The morphology of the family Pleurosigmataceae Mereschkowsky is documented using light and scanning electron mircroscopy. A historical overview of the treatment of the family is given and their interrelationships explored using cladistic analysis. Four new genera are described; Arcuatasigma gen. nov., Carinasigma gen. nov., Cochlearisigma gen.nov. and Costasigma gen. nov.; fourteen new combinations are proposed; and five new species described: Arcuatasigma addu sp. nov., Arcuatasigma castracanensis sp. nov., Donkinia lipscombensis sp. nov., Cochlearisigma ohsinsina sp. nov. and Costasigma simsii sp. nov. Plagiotropis is shown to be most closely related to the keeled members of the Pleurosigmataceae and is thus included in the Pleurosigmataceae, a new tribe is proposed to reflect this relationship, Carinasigmodeae tribe nov., which contains the new sub - tribe Rhocosigmodeae sub - tribe nov. within it to reflect the relationships of Rhoicosigma and Cochlearisigma. A further two tribes are described, Toxonideae tribe nov. and Pleurosigmodeae tribe. nov. Pleurosigma transilvanicum is formally transferred here to Gyrosigma transilvanicum (Pantocsek) Reid comb. nov. as it contains all the characters of Gyrosigma not Pleurosigma i.e. striae arranged in longitudinal and transverse rows. Hyalosigma is shown to be a member of the Pleurosigmataceae and is formally transferred to the family. (Quoted from the abstract).

Contents (chapter headings): Introduction (An introduction to the Atlantic Coastal Plain from North Carolina to New Jersey/ Chemical & Physical Characteristics of the Atlantic Coastal Plain Sites & A Brief Comparison with Waterbodies on Cape Cod/ General Characteristics of the Diatom Flora, Including a Comparison with the Flora from Waterbodies on Cape Cod)/ The Diatom Flora (General Information / The Taxa) / Literature Cited/ Plates / Appendices / Index. - Quotation from the 'Overview': Approximately 150 collections from 45 waterbodies situated along the Atlantic Coastal Plain were included in this volume. Three areas of focus, the Pocosin National Wildlife Refuge (11 sites), The Croatan National Forest (9 sites) and the Bladen Lakes State Forest (7 sites), are located along the coastal portion of North Carolina. The North Carolina waterbodies included shallow wetlands, small ponds, lakes, larger lakes, and a series of canals cut through significant sections of vegetation, which ranged in size from small depressions of 0.4 ha in size to over 6,475 ha (Phelps Lake). In general, these waterbodies were shallow, less than 3 meters deep and monomictic, not freezing over winter. All sites were associated with pocosin (early settlers used this term to define a low swampy ground, like a wooded swamp) or Carolina bay vegetation characteristic of this portion of the Atlantic Coastal Plain (Richardson et al., 1981). A fourth area of study included 13 waterbodies situated within the Pinelands National Reserve in southern New Jersey at the northern limit of the Atlantic Coastal Plain. The Pinelands National Preserve consists of sandy, well drained soils and is largely dominated by xerophytic vegetation. Observations of the diatom floras in five small Carolina bays situated on the Delmarva Peninsla in Maryland were also included in this work. The majority of the New Jersey and Maryland waterbodies were shallow lakes that would also be classified as warm monomictic.' - A total of 231 diatom taxa were recorded in the Atlantic Coastal Plain sites. 242 taxa were found in Cape Cod ponds, but not encountered further south in the Atlantic Coastal Plain sites. Additionally, 102 of the species reported from the Atlantic Coastal Plain were not found in Cape Cod waterbodies underscoring the fact that the diatom floras are different between the two regions.

This is a corrected version of the edition from 1994. - From the preface of the first printing: This new work will be invaluable to students of science, agriculturists and foresters as well as to residents and tourists in North Cyprus. However, it should also prove very useful in the South: the author's check-list for the North (grasses aside) runs to 1041 species and amounts, he calculates, to 77% of the island's equivalent total... For similar reasons the book will also deserve attention in neighbouring areas such as Turkey and the Greek Islands.(F.Nigel Hepper).

Price: 92.00

This volume contains data on 1381 species of green algae, belonging to 7 classes and 26 orders. The text and plates are arranged in alphabetical and according to taxonomic order (with one exception: infraspecific rank immediately follows the name of the species). Information about nomenclature for each species or infraspecific taxa, i.e., basionym, main synonyms (usually used when referring to the algal flora of Ukraine and still used in reference books), occurrence, and distribution in Ukraine with reference to world distribution. The distribution is shown using the local administrative place, type of water bodies, and non - aquatic biotopes specifically for the Ukraine and other countries on different continents, such as those that are 'widespread' or 'cosmopolitan' or reasonably common. The distribution maps show the distribution of the described taxa for the Ukraine. Some new nomenclatural combinations and taxa are validated. Original drawings and micrographs of new and of some rare species or taxa from Ukraine are described and noteworthy recordings for this flora are included.
Diatoms of Europe: Volume 06: Eunotia and some related genera - PUBLISHED!

Edited by H. Lange - Bertalot: Lange - Bertalot,H., Malgorzata Bak, Andrzej Witkowski, and Nadia Tagliaventi. 2011. 5053 figs. on 237 plates. 747 p. gr8vo. Hardcover. (ISBN 978-3-906166-88-9)

Price: 195.00

Description and illustrations of 192 taxa. 419 taxa of the family Eunotiaceae including synonyms are mentioned or discussed in detail. Eunotia belongs to the most prominent and species-richest diatom genera and is rather homogenous compared to other large genera. Restriction to freshwater of almost exclusively oligosaprobic habitats is a unique ecological feature of this genus which probably ranks 3rd at present after Nitzschia and Pinnularia in continental waters. Eunotia species play an important role as bio-indicators for water monitoring. The samples have been collected from by far most of the countries of Europe including the European part of Russia and several archipelagos like Greenland,other Arctic and Macaronesian Islands. The current research revealed for Europe 105 established and 54 new Eunotia taxa including four that are just recently published separately. Moreover eight taxa new to science originate from other subcontinents of the Holarctic Realm. In particular the Holarctic part of North America is compared to Europe. Apparently more than 80% of the European Eunotia taxa are living likewise in North America. In contrast to this geographic conformity the Paleo- and Neotropics host almost completely different taxa of the Eunotiacae - and much more than the Holarctic. Two local hotspots of high Eunotia species diversity, one in Finnish Lapland, the other one in Nova Scotia, Canada, host 70 and 73 taxa respectively. This surprising result shows that local Eunotia species diversity can be considerably higher than regional diversity of many European countries. Detailed determination keys that correspond to the illustrations will help to identify at least European and corresponding American taxa successfully.

This book focuses on botanical monography, which is the
cornerstone of all activities within plant systematics. Within the monograph is where the limits of species are presented, their characteristics, distributions, ecology, correct names, and evolutionary relationships. This information represents the basic statement about species of plants that grow on our planet, from which come additional studies on floristics (what plants grow where) and evolutionary biology. To understand the dynamics of the evolutionary process requires understanding what the closely related species are. Without this basic information, it is virtually impossible to understand mechanisms of organic evolution. Despite the acknowledged importance of botanical monography, in recent years many of the young generation of plant systematists have elected to concentrate more on DNA studies to the exclusion of monography. This raises concerns because it is in the monograph that hypotheses of relationships are revealed, and that are subsequently tested with DNA data. Hence, if no new monographs are being produced, we will soon have no new hypotheses to continue testing.

This new book addresses these problems and offers solutions. The book has four parts: (1) The value of botanical monography (2) Data and analysis in monographic work; (3) Literature and nomenclature for monographic research; and (4) Perspectives. The objectives in the 12 chapters of the book, all authored by established monographers, are to present ideas on the importance of monography and those tools that are available for doing successful monographic work.
