Описание: Freshwater fish are one of the most diverse vertebrate groups, but are also amongst the most threatened. This is the first assessment of the global state of freshwater fish diversity, providing a comprehensive synthesis of the opportunities, challenges and barriers facing the conservation of freshwater fish biodiversity.
With more than 15,000 species, nearly a quarter of the total number of vertebrate species on Earth, freshwater fishes are extremely varied. They include the largest fish species, the beluga at over 7 meters long, and the smallest, the Paedocypris at just 8 millimeters, as well as the carnivorous, such as the piranha, and the calm, such as the Chinese algae eater. Certain species evolve rapidly, cichlids for example, while others transform very slowly, like lungfish. The fossils of these animals are very diverse in nature, sometimes just small scattered bones where sites correspond to ancient river beds or magnificent fossils of entire fish where there was once a lake.
This book covers the history of these fishes over the last 250 million years by exploring the links between their biological evolution and the paleogeographic and environmental transformations of our planet, whether these be gradual or sudden.
Gathers and synthetizes data from a vast number of publications regarding past freshwater assemblages and several fish lineages that invaded freshwaters
Describes the work of the author's own team, concerning fauna from the Cretaceous of France, Morocco, and Thailand
Presents the recent results of the tempo of diversification in freshwater environments and the evolutionary histories of clades and gar lineages
