This book was released on 1963 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The successive stages in the life-history of Homalometron pallidum, a parasite of Fundulus heteroclitus, described by Linton, 1901 and named by Stafford, 1904, have been discovered and identified. The asexual generations are in Hydrobia minuta and the metacercarial stages are encysted in Gemma gemma, H. minuta, and small polychaete annelids which serve as secondary intermediate and transfer hosts. Knowledge of larval as well as adult stages gives a better basis for determination of the evolution and systematics of the allocreadiid-leprocreadiid trematodes. The subfamily Homalometroninae contains marine, brackish-, and freshwater species. Manter (1963) discussed the geographical dispersal of the group and the possible significance of present distribution for the phylogeny and evolution of the parasites and of their hosts. In his opinion, the subfamily illustrates an evolution from marine ancestors, through secondary-division hosts, to become parasites of fresh-water fishes. Results of the present investigation support his hypothesis. (Author).

Download or read book Parasitic Worms Of Fish written by Hartford Williams and published by CRC Press. This book was released on 1994-01-14 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish are a unique group which harbour some 30,000 species of helminths that do not occur in other vertebrates. This book deals specifically with parasitic worms of fish. It covers every aspect of their biology including identification, life-cycles, hostparasite relationships and ecology. It discusses approaches to studying parasitic worm infections, preference of species for particular host species, preference for dwelling in certain organs and tissues, biogeography, seasonality of infections and how parasites have evolved in parallel with their hosts. The book concludes with discussions of fish worms causing diseases in nature and in fish-farms.
Download or read book The Evolution of Parasitism A Phylogenetic Perspective written by and published by Elsevier. This book was released on 2003-12-09 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitology continues to benefit from taking an evolutionary approach to its study. Tree construction, character-mapping, tree-based evolutionary interpretation, and other developments in molecular and morphological phylogenetics have had a profound influence and have shed new light on the very nature of host-parasite relations and their coevolution. Life cycle complexity, parasite ecology and the origins and evolution of parasitism itself are all underpinned by an understanding of phylogeny. The Evolution of Parasitism - A Phylogenetic Perspective aims to bring together a range of articles that exemplifies the phylogenetic approach as applied to various disciplines within parasitology and as applied by parasitologists. Unified by the use of phylogenies, this book tackles a wide variety of parasite-specific biological problems across a diverse range of taxa. Includes important contributions from leading minds in the field such as Serge Morand, Francisco Ayala and Mark Blaxter, among others Second in the ISI Parasitology List in 2002 with an Impact Factor of 4.818 Series encompasses over 35 years of parasitology coverage

Download or read book Guide to the Parasites of Fishes of Canada written by David I. Gibson and published by NRC Research Press. This book was released on 1984 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide arranges information on trematode parasites of Canadian fishes by subclass (Aspidogastrea and Digenea), order, superfamily, family, subfamily, and genera. No descriptions are included for individual species because of the large number of taxa involved, but illustrations of members of each genus are provided. Data supplied in the guide include scientific name, synonyms, the position or organ in the fish where the parasite has been reported, hosts, distribution in Canadian waters, authors responsible for the published records of a particular parasite, and comments on the systematics, nomenclature, records, or other aspects of the biology of the parasite. Diagnoses are presented for all taxa down to generic level, and keys are included down to the species level.

Available in PDF, EPUB and Kindle. Book excerpt: Information on the parasites of Canadian fishes published between the years 1978 and 1993, inclusive, is assembled as Parasite-Host and Host-Parasite lists. The 925 named species of parasites are reported on 292 species of Canadian fishes. The Parasite-Host list is organized on a taxonomic basis and identifies for each species its habitat (freshwater, marine, or brackish), site of occurence in its host(s), species host(s), known geographic distribution within Canadian waters, and the published source for each host and localty record. The Host-Parasite list is organized according to the taxonomy of the hosts and is accompanied by data on the known Canadian distribution of the parasites. For both the Parasite-Host and Host-Parasite lists, a "Remarks" section containing explanatory comments concerning systematics, nomenclature, and notes on other specific items is included as warranted. In addition to listing the cited references, as supplentary list of references is included to cover other Canadian literature on fish parasites.
