Download or read book Hermaphroditism and Mating Systems in Fish written by Tetsuo Kuwamura and published by Springer Nature. This book was released on 2022-12-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive review of hermaphroditism in fishes. It focuses on the behavioral ecology of functional hermaphroditism in fishes and discusses its evolution. Approximately 99% of all vertebrate species consist of separate-sex individuals (gonochorists), i.e., pure males and pure females. The other 1% of vertebrate species are hermaphroditic, and almost all of them are fishes. Among hermaphroditic fishes, four major types of hermaphroditism are known: simultaneous (or synchronous) hermaphroditism, protandry (male-to-female sex change), protogyny (female-to-male sex change), and bidirectional sex change (or reversed sex change in protogynous species). The book examines the occurrence of hermaphroditism in relation to phylogeny and mating systems. It also reviews the hypotheses for the evolution of hermaphroditism, and the size-advantage model, which is the main theory for the evolution of sex change, tested in relation to the mating system. The appendix in the last chapter provides an annotated list of hermaphroditic fish species (ca. 500 spp.).

Download or read book Ecology of Australian Freshwater Fishes written by Paul Humphries and published by CSIRO PUBLISHING. This book was released on 2013-04-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume reviews our past and present understanding of the ecology of Australian freshwater fishes. It compares patterns and processes in Australia with those on other continents, discusses the local relevance of ecological models from the northern hemisphere and considers how best to manage our species and their habitats in the face of current and future threats. In view of these challenges, the need for redress is urgent. The chapters are written by some of our foremost researchers and managers, developing themes that underpin our knowledge of the ecology, conservation and management of fish and fish habitats. For each theme, the authors formulate a synthesis of what is known, consider the need for new perspectives and identify gaps and opportunities for research, monitoring and management. The themes have an Australian context but draw upon ideas and principles developed by fish biologists in other parts of the world. The science of freshwater fish ecology in Australia has grown rapidly from its roots in natural history and taxonomy. This book offers an introduction for students, researchers and managers, one that the authors hope will carry Australian fish biology and resource management to new levels of understanding.

This book was released on 2023-07-31 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document reviews and compiles the scientific information available on the new and non-indigenous fish and decapod crustacean species in the Adriatic Sea, central Mediterranean Sea. For fish, the new species are those whose presence in the Adriatic Sea was recorded recently, since the year 2000. For decapod crustaceans, only alien species found in the Adriatic Sea after the Second World War are dealt with. In total, 15 crustaceans and 52 fish species were selected and presented in this handbook. Following an introductory section, giving a general overview on the Adriatic Sea geographical characteristics, this document reviews, in its first part, the ichthyofauna and decapod crustaceans in the area. The second part of the document provides a description of each new species including synonyms, meristic formula, main morphologic features, bio-ecology, known geographical distribution, relevance and reference literature. This work was designed and implemented within the framework of the FAO-AdriaMed Project “Scientific Cooperation to Support Responsible Fisheries in the Adriatic Sea”.

This book was released on 2018-11-15 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multivolume field guide covers the species of interest to fisheries of the major marine resource groups exploited in the Eastern Central Atlantic. The area of coverage includes FAO fishing area 34 and part of 47. The marine resource groups included are bivalves, gastropods, chitons, cephalopods, stomatopods, shrimps, lobsters, crabs, hagfishes, sharks, batoid fishes, chimaeras, bony fishes and sea turtles. The introductory chapter outlines the environmental, ecological, and biogeographical factors influencing the marine biota, and the basic components of the fisheries in the Eastern Central Atlantic. Within the field guide, the sections on the re source groups are arranged phylogenetically according to higher taxonomic levels such as class, order, and family. Each resource group is introduced by general re marks on the group, an illustrated section on technical terms and measurements, and a key or guide to orders or families. Each family generally has an account summarizing family diagnostic characters, bi o logical and fisheries in formation, notes on similar families occur ring in the area, a key to species, a check list of species, and a short list of relevant literature. Families that are less important to fisheries include an abbreviated family account and no de tailed species in formation. Species in the important families are treated in detail (arranged alphabetically by genus and species) and include the species name, frequent synonyms and names of similar specie s, an illustration, FAO common name(s), diagnostic characters, biology and fisheries in formation, notes on geo graphical distribution, and a distribution map. For less important species, abbreviated accounts are used. Generally, this includes the species name, FAO common name(s), an illustration, a distribution map, and notes on biology, fisheries, and distribution. Each volume concludes with its own index of scientific and common names.

Download or read book Conservation Of Endangered Freshwater Fish In Europe written by Arthur Kirchhofer and published by Springer Science & Business Media. This book was released on 1996-01-26 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.

Download or read book Invasive Alien Species written by NOBANIS and published by Nordic Council of Ministers. This book was released on 2015-06-09 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive alien species are one of the main drivers of biodiversity loss, due to their ability to disperse and cause negative effects on native species and the environment. To reduce the introduction of invasive alien species in the future, preventive measures need to be implemented, and knowledge about pathways of introduction of new and potentially invasive alien species can facilitate tailor-made measures. The aim of this project is to contribute to the fulfilment of obligations in the CBD Aichi target 9 and the EU Biodiversity Strategy 2020 target 5, by identifying and prioritising the most significant pathways of introduction for invasive alien species by conducting a pathway analysis and horizon scanning. This identification and prioritisation is done for 10 participating countries and territories part of the NOBANIS network to assist them in minimising and preventing further introductions and establishment of invasive alien species. Based on the results from the pathway analysis and horizon scanning, this report presents a prioritised list of pathways of interest, general recommendations on measures to control pathways of interest, and advice on development of an early warning system for invasive alien species.
