Diversity of fish - Wikipedia
网页Fish species diversity is roughly divided equally between marine (oceanic) and freshwater ecosystems. Coral reefs in the Indo-Pacific constitute the centre of diversity for marine fishes, whereas continental freshwater fishes are most diverse in large river basins of tropical rainforests, especially the Amazon, Congo, and Mekong basins.
Global determinants of freshwater and marine fish genetic diversity
网页2020年2月10日 · Using a mined database of 50,588 georeferenced mitochondrial DNA barcode sequences (COI) for 3,815 marine and 1,611 freshwater fish species respectively, we examined the correlation between...
Human impacts on global freshwater fish biodiversity | Science
网页2021年2月19日 · Here, we assess the extent to which six key facets of freshwater fish biodiversity—taxonomic, functional, and phylogenetic richness, plus the dissimilarity among river basins in each of these categories—have changed over the past two centuries in 2456 river basins, covering almost the entire continental surface …
Integrating abundance and functional traits reveals new global
网页2013年9月25日 · We use data from standardized quantitative surveys of 2,473 marine reef fish species at 1,844 sites, spanning 133 degrees of latitude from all ocean basins, to identify new diversity hotspots...
Diversity, pattern and ecological drivers of freshwater fish in …
网页2020年4月10日 · Historical factors played a primary role, or at least a comparable role as that of contemporary climate, in explaining freshwater fish diversity patterns in the study area. We provide for the first time a basic framework for cataloguing the diversity and distribution pattern of freshwater fishes HUs at the tributary and sub-basin levels in this ...
Unraveling fish diversity and assembly patterns in a temperate …
网页2023年12月1日 · The loss of freshwater biodiversity has drawn greater attention to fish diversity and community assembly patterns. However, traditional survey methods, such as ground cages and electrofishing, may cause damage to fish communities and have become increasingly unsuitable for frequent and large-scale fish diversity surveys.
Fish diversity patterns along coastal habitats of the southeastern ...
网页2022年3月4日 · We found similar diversity of fish species throughout the year in coastal habitats on San Cristóbal Island, and the diversity seems not to be influenced by seasonality.
1 Fish diversity: Classification and variety - Oxford Academic
网页Fish represent huge diversity in shape, size, colour and habit. The distribution of particular genera may be widespread, either naturally (deep-sea grenadiers) or by introduction (trout, carp) or severely limited (desert pupfish, cave-fish), and the numbers of individuals in different species may also be extremely numerous (some marine species ...
Explaining the ocean's richest biodiversity hotspot and global …
网页2018年10月10日 · Our results also shed light on the origins of freshwater fish diversity. We found that freshwater percomorph diversity, though similar in magnitude to the CIP, is dominated by a few ancient clades with exceptional species richness and high diversification rates (figures 1 and 3; electronic supplementary
Patterns in Freshwater Fish Diversity - ResearchGate
网页2021年1月1日 · This chapter provides a brief overview of freshwater fish diversity globally, the factors underlying diversity patterns among and within river basins and phylogenetic groups, and the main...
