A Guide to the Described Larval Stages of Brachyuran and Anomuran Crabs of North Carolina
Author: Larvae of Anomuran and Brachyuran Crabs of North Carolina
Author: Stephan BullardPublisher: BRILL
ISBN: 9004475907
Category : Science
Languages : en
Pages : 143
Book Description
This guide is a compilation of the available descriptions of the zoeal and megalopal stages of anomuran (Families Porcellanidae, Albuneidae, and Hippidae) and brachyuran crabs found off of North Carolina, USA. Descriptions of the zoeae of 44 species and the megalopae of 34 species are included, along with keys for their identification. The purpose of the key is to allow investigators with minimal taxonomic background to identify crab larvae to the species level. To this end, lengthy and complex morphological descriptions have been avoided and the focus has been on gross morphological differences among taxa.
The Biology of Terrestrial Isopods

ISBN: 9047412850
Category : Science
Languages : en
Pages : 394
Book Description
Oniscids are wonderful model organisms for studies addressing more general biological questions, and they arguably demonstrate the best evolutionary progression in any extant group of organisms. Their unique properties as terrestrial crustaceans living in a wide range of habitats from coast to desert offer great advantages to study physiological and behavioural adaptations, ecological, phylogenetic, and biogeographical patterns, and evolutionary processes. This volume contains contributions, which were presented at the 5th International Symposium on the Biology of Terrestrial Isopods that took place on Crete, May 2001, and which was dedicated to the memory of the late Marie Flasarova. All papers have been peer-reviewed before inclusion in the book. The contributions give a well balanced account of current research on all aspects - covering systematics, ecology, biogeography, morphology, physiology, immunology, endocrinology, behaviour, and hostparasite relationships - of biology of the remarkable creatures included in the Isopoda suborder Oniscidae, the only crustaceans that have conquered almost all terrestrial habitat types. This book will prove useful to all crustacean researchers, working on either terrestrial, freshwater or marine organisms.
Larval Stages of Northeastern Atlantic Crabs

Category : Science
Languages : en
Pages : 392
Book Description
North East Atlantic waters are inhabited by over 120 species of lobster and crab-like crustaceans. Accurate identification of their larvae is necessary for basic research into these animals and also in the assessment of adult stocks of the commerical species. The larval stages of many occur frequently in plankton but are often difficult to identify due to limited knowledge of their morphology.
Zooplankton of the Atlantic and Gulf Coasts

Book Description
Zooplankton are critical to the vitality of estuaries and coastal waters. In this revised edition of Johnson and Allen's instant classic, readers are taken on a tour of the miniature universe of zooplankton, including early developmental stages of familiar and diverse shrimps, crabs, and fishes. Zooplankton of the Atlantic and Gulf Coasts details the behavior, morphology, and coloration of these tiny aquatic animals. Precise descriptions and labeled illustrations of hundreds of the most commonly encountered species provide readers with the best source available for identifying zooplankton. Inside the second edition• an updated introduction that orients readers to the diversity, habitats, environmental responses, collection, history, and ecological roles of zooplankton• descriptions of life cycles• illustrations (including 88 new drawings) that identify 340-plus taxa and life stages• range, habits, and ecology for each entry located directly opposite the illustration• appendices with information on collection and observation techniques and citations of more than 1,300 scientific articles and books

Occurrence of Larval, Juvenile, and Mature Crabs in the Vicinity of Beaufort Inlet, North Carolina (Classic Reprint)

Book Description
Excerpt from Occurrence of Larval, Juvenile, and Mature Crabs in the Vicinity of Beaufort Inlet, North Carolina During 1962 and 1963, as a part of the blue crab studies at the National Marine Fisheries Service Laboratory, Beaufort, n.c., plankton samplers and bottom trawls were fished off shore to determine the seasonal distribution and abundance of various crab stages. Plank ton stations were sampled twice a month from May through November 1962, and bottom trawl samples for juvenile and adult crabs were taken twice a month from June 1962 through December 1963. The study provided information on the species present and their time of spawning. Also, our knowledge of the size of the crab populations was increased.

Studies on the Larval Development of N̲e̲o̲p̲a̲n̲o̲p̲e̲ T̲e̲x̲a̲n̲a̲ S̲a̲y̲i̲ (Smith) and Other Crabs of the Family Xanthidae (Brachyura)

Book Description
Neopanope texana sayi, Hexapanopeus angustifrons, and Piluminus sayi have been reared in isolation from eggs through the first crab stage with about 80% survival. These species hatched in the laboratory as first zoeae and underwent three more zoeal stages and one megalopal stage before metamorphosis to the first crab stage. The duration of the larval stages was twice as long when the zoeae were fed Artemia nauplii plus algae, as when fed Artemia alone. Larvae did not survive when fed algae alone but lived longer than those not fed at all. The mechanism of this inhibition of development by algae is unknown. A morphological description of the larvae of Neopanope texana sayi is given. While no variation in the number of larval stages was found, variations in the zoeae at each stage are described. Some of these variable characters are those frequently used in comparative work on zoeae. (Author).
