This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study presents the inventory of sea spiders (Pycnogonida) sampled during the Madibenthos Expedition in Martinique (West Indies). Species were discriminated leaning on morphological and molecular data. A total of 761 specimens are classified in 72 species, 16 genera and nine families. Thirteen new species are described: Ammothella dirbergi sp. nov., A. krappi sp. nov., Tanystylum boucheti sp. nov., T. ingrallis sp. nov., Ascorhynchus iguanarum sp. nov., Eurycyde kaiouti sp. nov., Nymphon dorlis sp. nov., N. ludovici sp. nov., N. martinicum sp. nov., N. timons sp. nov., Anoplodactylus madibenthos sp. nov., Pycnogonum cesairei sp. nov. and Rhynchothorax sidereus sp. nov. We describe a neotype for Anoplodactylus micros Bourdillon, 1955 from the type locality. Martinique now includes 79 species of sea spiders, mostly endemic to the Tropical Northwestern Atlantic, cosmopolitan or shared with the South America Atlantic coast. Some species are potentially introduced. However, our knowledge of the distribution of species found in Martinique is probably biased by the scarcity of diagnostic morphological characters. Also, nine potentially cryptic species (discriminated on genetic data alone), are identified, shedding light on the overlooked diversity of sea spiders in the Tropical Northwestern Atlantic. Therefore, we call for a more widespread use of barcoding in sea spiders.

Available in PDF, EPUB and Kindle. Book excerpt: "This Synopsis covers all eighty-four species recorded at all depths from the north-east Atlantic, east of the Mid-Atlantic Ridge, south of the Wyville Thompson Ridge, and north of the Azores Fracture Zone and of the entrance to the Mediterranean (thus >38°N). Keys to families, genera and species are provided along with notes on species and their distribution. The volume represents a comprehensive revision of British sea spiders (King, 1974), incorporating new information and expanded to include 84 species from 12 families. The pycnogonids, or 'sea spiders' are a class of the phylum Arthropoda with few clear affinities to any other arthropod group. They are exclusively marine and occur from the littoral zone to the abyss and world-wide. Almost all known species from the north -east Atlantic are free-living as adults, although some endoparasitic species are known from elsewhere in the world."--Publisher's description.

Book Synopsis Deep-Sea Pycnogonids and Crustaceans of the Americas by : Michel E. Hendrickx
Download or read book Deep-Sea Pycnogonids and Crustaceans of the Americas written by Michel E. Hendrickx and published by Springer Nature. This book was released on 2021-03-01 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.
Book Synopsis Taxonomy and Systematics of the Australian Micropholcommatidae (Arachnida by : Michael G. Rix

Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] The southern-temperate spider family Micropholcommatidae is a poorly-studied taxon of uncertain limits and uncertain affinities. Since the first Australian species were described in the early twentieth century, and the family was erected in 1944, the taxonomic status and phylogenetic placement of the Micropholcommatidae have been the subject of ongoing debate. Various phylogenetic hypotheses have been proposed for the family, but these hypotheses have never been tested with a robust phylogenetic analysis a problem compounded by the inadequate state and confusing history of micropholcommatid taxonomy. To address the many gaps in our understanding of micropholcommatid interrelationships, this thesis will present a comprehensive systematic treatment of the family. Using a combination of molecular phylogenetic, morphological cladistic and taxonomic methods, micropholcommatid diversity is documented and tested at multiple systematic levels, with an alpha-taxonomic and biogeographic focus on the diverse Australian fauna. The taxonomic contribution is substantial throughout, with one new family, two new subfamilies, one new tribe, 14 new genera and 37 new species described. A combined molecular phylogenetic study is presented in Chapter 2, as a 'first pass' exploration of the monophyly, limits and phylogenetic position of the family Micropholcommatidae. The analyses incorporated 50 ingroup spider species, including 23 micropholcommatid taxa, with nucleotide sequences obtained from two nuclear ribosomal RNA genes (18S and 28S). ...The new subfamily Gigiellinae is also described for two enigmatic species in the newly-described genus Gigiella, known only from the temperate Nothofagus rainforests of south-eastern Australia and southern Chile. As a final contribution to micropholcommatid taxonomy, and as an extension to the cladistic analyses presented in Chapter 5, the new spider family Teutoniellidae is proposed in Chapter 6 for three genera from South America, South Africa and Australia. Teutoniellid monophyly is evidenced by at least two unambiguous synapomorphies, and the morphology of the family is described in relation to other symphytognathidan and EbCY spider taxa. The nominate genus Teutoniella is redescribed to include three species from South America, along with an additional new species from Tasmania. Two new teutoniellid genera are also described, each for a single new species from South Africa: Inflaticrus ansieae is described from the Langeberg Range, east of Cape Town; and Woldius hennigi is described from near Pietermaritzburg, north-west of Durban. In summary, this thesis provides a taxonomic and phylogenetic framework for all future research on micropholcommatid spiders. It presents new data on the phylogeny, phylogenetic position, composition, biogeography, molecular evolution and natural history of a previously poorly-known group of spiders, and highlights a number of remaining gaps in our knowledge of micropholcommatid and araneoid systematics. As a novel contribution to scholarship, this thesis synthesises taxonomic and phylogenetic hypotheses at multiple systematic levels, and tests those hypotheses with original, combined datasets.

Download or read book Whip Spiders written by Peter Weygoldt and published by BRILL. This book was released on 2021-10-25 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whip spiders (Amblypygi) can be large and terrifying animals with strong, raptorial pedipalps and long antenniform first legs that can produce a span of as much as 60 cm. Others are small and scarcely span 5 cm. They all lead a secretive nocturnal life and are extremely dangerous to other arthropods and small vertebrates. In contrast to spiders and scorpions, they are of no commercial, economic or medical importance and they are difficult to study in the field because of their nocturnal habits, possible reasons why they have been greatly neglected until recently, by scientists and naturalists. Whip spiders represent an old group that dates back to the Carboniferous period. Their partly primitive and partly derived morphological characters and habits make the study of these animals interesting, while observation of their behaviour greatly increases our knowledge and understanding of arachnids in general. In this book the author describes their morphology and systematics, their life history, their fascinating sensory biology, their complex mating dances and reproductive biology, and their ecology and distribution. Thus he has made a significant contibution to a better understanding of the morphology and biology of the Arachnida as a whole. Whip Spiders is an outstanding contribution to science and it will be of interest for anyone with an interest in Arachnida and for those keeping and breeding spiders.

Available in PDF, EPUB and Kindle. Book excerpt: The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.
