Amphilophus Hogaboomorum
''Amphilophus'' is a genus of cichlid fishes from Central America, ranging from southern Mexico to Panama. The genus currently contains 23 species, including several that are well-known from the aquarium trade. However, studies led by Oldřich Říčan in 2008 and 2016 suggested that several species within ''Amphilophus'' should be moved to the genus ''Astatheros''. Species proposed to be moved to ''Astatheros'' in 2008 were ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. macracanthus'' (which would be the type species for ''Astatheros''), ''A. margaritifer'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus''. Further genetic studies led Říčan to put ''A. macracanthus'' in ''Astatheros'', but to put ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus'' within the genus ''Cribroheros''. Říčan's study suggests that the ''Astatheros'' species a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
