Abstract

En esta ocasión nos complace presentar esta obra, que describe un importante grupo de vertebrados, como son los peces del Alto Nangaritza, ubicado en la Cordillera del Cóndor, considerada como una región invaluable desde el punto de vista ecosistémico y de biodiversidad. Se describe desde los nombres científicos hasta las posibles distribuciones espaciales de las especies encontradas, acompañadas de fotografías de alta calidad. Esta guía es fruto de varios muestreos desarrollados en el año 2016, en los ríos Nangaritza y Numpatakaime en la zona denominada Alto Nangaritza. En los muestreos participaron varios miembros de las comunidades locales, quienes además aportaron con sus conocimientos relacionados con los nombres comunes de las especies. Esperamos que esta obra contribuya a la difusión de conocimientos, a la conservación de este significativo grupo de fauna, que constituye un importante recurso para las comunidades locales.

... This has also been a region of historical conflict over land disputes between Ecuador and Peru (Schulenberg & Awbrey, 1997). Recent years have seen the development of new mining operations and dam construction, which have stimulated efforts to study the fishes in the region (Barriga, 1997;Nugra et al., 2018). ...

Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's freshwater fishes. Concerns were identified for 35 species, most of which are native to the Amazon region, and overfishing of Amazonian pimelodid catfishes emerged as a major issue. However, much of the information needed to make decisions across fish groups and regions was not available, hindering the process and highlighting the need for a review of the conservation threats to Ecuador's freshwater fishes. Here, we review how the physical alteration of rivers, deforestation, wetland and floodplain degradation, agricultural and urban water pollution, mining, oil extraction, dams, overfishing, introduced species and climate change are affecting freshwater fishes in Ecuador. Although many of these factors affect fishes throughout the Neotropics, the lack of data on Ecuadorian fish communities is staggering and highlights the urgent need for more research. We also make recommendations, including the need for proper enforcement of existing environmental laws, restoration of degraded aquatic ecosystems, establishment of a national monitoring system for freshwater ecosystems, investment in research to fill gaps in knowledge, and encouragement of public engagement in citizen science and conservation efforts. Freshwater fishes are an important component of the cultural and biological legacy of the Ecuadorian people. Conserving them for future generations is critical.

Esse livro, portanto, foi idealizado com o objetivo de reunir e sistematizar as informações acerca da riqueza ictiofaunística das bacias inseridas na área do Quadrilátero Ferrífero, permitindo uma forma prática e eficiente de identificação de peixes amostrados em trabalhos técnicos e científicos. Espera-se, assim, que a comunidade acadêmica e técnica tenham em mãos material de boa qualidade e eficiente para auxiliar na identificação dos principais grupos que ocorrem nas drenagens superiores (alto) dos rios Paraopeba, das Velhas e Doce.

Please visit the authors' website for this book: https://sites.google.com/view/fishes-of-the-world-5/welcome. Fishes of the World, Fifth Edition is the only modern, phylogenetically based classification of the world’s fishes. The updated text offers new phylogenetic diagrams that clarify the relationships among fish groups, as well as cutting-edge global knowledge that brings this classic reference up to date. With this resource, you can classify orders, families, and genera of fishes, understand the connections among fish groups, organize fishes in their evolutionary context, and imagine new areas of research. To further assist your work, this text provides representative drawings, many of them new, for most families of fishes, allowing you to make visual connections to the information as you read. It also contains many references to the classical as well as the most up-to-date literature on fish relationships, based on both morphology and molecular biology. The study of fishes is one that certainly requires dedication—and access to reliable, accurate information. With more than 30,000 known species of sharks, rays, and bony fishes, both lobe-finned and ray-finned, you will need to master your area of study with the assistance of the best reference materials available. This text will help you bring your knowledge of fishes to the next level. - Explore the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships of fishes - Access biological and anatomical information on more than 515 families of living fishes - Better appreciate the complexities and controversies behind the modern view of fish relationships - Refer to an extensive bibliography, which points you in the direction of additional, valuable, and up-to-date information, much of it published within the last few years. 711 pages, Index, Bibliography

This second volume of the Global Register of Migratory Species complements the reference list of migratory vertebrate species with fishes and songbirds, in printed and digital format. The enclosed GROMS CD contains an improved and updated version of the GROMS database, including 5,600 references, full-text documents and 1,000 species distribution maps in GIS format. These are complemented by additional, relevant geodata sets such as country files, protected wetlands or oil spills. The user guide empowers novices to make simple database searches, and customize their own maps with the enclosed lightweight GIS freeware. Advanced users will find the full tutorial of a GROMS Workshop for Power Users on CD, with examples of advanced data-mining and GIS intersections, to enable pursuit of their own research questions related to migratory species conservation. This volume presents examples of what can be achieved by combining GROMS with other species databases or regional GIS datasets, thereby zooming in from global to regional scales. Up to now, 4,358 species have been identified as definitely or most probably migratory, exhibiting predictable and cyclical migrations of more than 100 km, including 1,895 migratory fish species. Both volumes together illustrate the particular requirements of an information system serving the conservation of migratory species.
