The Thelypteridaceae is among the largest fern families, with over 1000 species, and comprises about 10% of all fern diversity. The family is cosmopolitan and most diverse near the equator, although species range as far north as Greenland and Alaska, and as far south as southern New Zealand. The generic classification of the Thelypteridaceae has been the subject of much controversy among authors. Proposed taxonomic systems have varied from recognizing more than 1000 species in the family within a single genus, Thelypteris, to systems favoring upwards of 30 genera. Insights on intrafamilial relationships have been gained from recent phylogenetic studies, especially for the Neotropics, however, in the most recent classification, 10 of 30 recognized genera are either non-monophyletic or untested. In the present study, we sequenced nDNA across 400 loci for 621 accessions, representing all recognized genera. Our phylogenetic results, coupled with morphological study, provide a foundation for our new generic classification system. Major taxonomic changes include the recircumscription of 14 genera, descriptions of four new genera and three subgenera, the elevation of three sections to generic status, the resurrection of one genus, the inclusion of two genera in synonymy, and 181 new combinations. Our newly recognized monophyletic genera demonstrate greater geographic coherence than previous taxonomic concepts suggested. Additionally, our results demonstrate that certain morphological characters, such as frond division, are evolutionarily labile, and are the result of repeated instances of convergent evolution, and are thus inadequate for defining genera.

A comprehensive, richly illustrated photographic field guide to the ferns and lycophytes of the eastern United States and Canada This is a comprehensive photographic field guide to the ferns, spikemosses, clubmosses, and quillworts of eastern North America. Accessible yet scientifically accurate, the book will appeal to beginners and experts alike and enhance the field experience of any user. Keys, range maps, detailed color photographs, and facing-page species descriptions aid exploration and allow reliable identification of all 305 species found in the area covered by the book—the United States east of the Mississippi and contiguous Canada, except for extreme northern and northeastern Canada. An introduction provides an easy-to-understand overview of identifying characteristics, life cycles, and evolutionary history. Checklists allow readers to record species they have seen, in four subregions. Indexes feature a complete list of common and scientific names, including synonyms, ensuring that users can find the plants they are looking for and keep track of changes in taxonomy. In addition, information about hybrids, polyploids, and reticulate relationships is provided, illuminating the fascinating processes that have led to such a rich diversity of species. Modern and innovative, this is the definitive guide to the ferns and lycophytes of eastern North America. Covers all 305 species, belonging to 96 genera and 30 families Features detailed color photos of all species—and facing-page species descriptions Provides checklists for keeping track of species seen Includes common and scientific names and notable synonyms

Ferns, collectively, represent an ancient species of vascular plant which has a direct connection to the beginning of life on Earth. Today they are valued for their ornamental appeal, environmental benefit or as sources of health benefiting metabolites. Current pteridology, the study of fern, encompasses a wide range of research activities including, but not limited to, plant physiology, stress tolerance, genetics and genomics. The goal of this book is to compile the most relevant research done with ferns during the last decade. It is organized into four parts: I, Biology and Biotechnology; II, Evolution and Conservation; III, Metabolism and Genetic Resources, and IV, Environment. Each section reveals the utilization of ferns as a tool to explore challenges unique to plant development and adaptation. This project represents our collective effort to raise the awareness of ferns as a model system to study higher plant functions. Among the distinctive features of our proposed book are: (i) a wide range of topics with contributing researchers from all around the world, and (ii) recent advances of theoretic and applied knowledge with implications to crop species of economic value.

This systematic treatment of the ferns and allied plants provides a modern classification of the Pteridophyta based on an assess ment of the wealth of new data published during the last few decades as well as on our own research. The accounts of the gen era include systematics, ecology, geography, spores and cytology and often other aspects of their biology. The scope of the work has involved all genera and the Old World species of those gen era represented in America. For a few American genera, that are especially complex in the Old World, it has been necessary to limit their treatment to the American representatives and this is specifically indicated in those cases. The eight American genera that do not occur in the tropics are treated in less detail. They are Camptosorus, Gymnocarpium, Matteuccia and Onoclea of North America, Arthropteris and Thyrsopteris of the Juan Fernandez Islands, Pleurosorus of southern South America, and the amphi tropical Cryptogramma. The complete generic nomenclature is included, except in a few specified cases where taxonomic complexities of the Old World elements have not been resolved. The synonyms and ac cepted names of subgeneric and sectional taxa are included only when pertinent to the generic nomenclature or to an infrageneric classification. Only the name of a publishing author is cited. There is no bibliographic purpose served by including the name of a person who was the source of, but did not validly publish, a name or epithet.

Mountains, Climate and Biodiversity: A comprehensive and up-to-date synthesis for students and researchers Mountains are topographically complex formations that play a fundamental role in regional and continental-scale climates. They are also cradles to all major river systems and home to unique, and often highly biodiverse and threatened, ecosystems. But how do all these processes tie together to form the patterns of diversity we see today? Written by leading researchers in the fields of geology, biology, climate, and geography, this book explores the relationship between mountain building and climate change, and how these processes shape biodiversity through time and space. In the first two sections, you will learn about the processes, theory, and methods connecting mountain building and biodiversity In the third section, you will read compelling examples from around the world exploring the links between mountains, climate and biodiversity Throughout the 31 peer-reviewed chapters, a non-technical style and synthetic illustrations make this book accessible to a wide audience A comprehensive glossary summarises the main concepts and terminology Readership: Mountains, Climate and Biodiversity is intended for students and researchers in geosciences, biology and geography. It is specifically compiled for those who are interested in historical biogeography, biodiversity and conservation.
