Charles Frédéric Girard
Charles Frédéric Girard (; 8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Biography Girard was born on 8 March 1822 in Mulhouse, France. He studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil Wa ...

Temperate Perch
Percichthyidae, the temperate perches, are a family of freshwater ray-finned fish found in Australia and southern South America. Formerly placed in the order Perciformes, they are now placed in the order Centrarchiformes. The name Percichthyidae derives from the Latin ''perca'' for perch and Ancient Greek ἰχθύς, ''ichthys'' for fish. Evolution Potential percichthyid fossil remains are known from the Early Paleocene of the El Molino Formation of Bolivia; these remains have been described as resembling those of the fossil '' Percichthys hondoensis'' from the Eocene of Argentina. One articulated specimen is known from the Paleocene portion of the formation, but other remains are known from the Maastrichtian beds of the formation, indicating that percichthyids could have potential Cretaceous origins. However, the condition of this material is unclear. Another fossil percichthyid, '' Percichthys lonquimayiensis'' from Chile, was initially dated to the Paleocene, but further ...

The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leonard Blomefield
Leonard Jenyns (25 May 1800 – 1 September 1893) was an English clergyman, author and naturalist. He was forced to take on the name Leonard Blomefield to receive an inheritance. He is chiefly remembered for his detailed phenology observations of the times of year at which events in natural history occurred. Personal life Jenyns was born in 1800 at No. 85 Pall Mall, London, the home of his maternal grandfather. He was the youngest son of George Leonard Jenyns of Bottisham Hall, Cambridgeshire, a magistrate, landowner and a prebendary of Ely Cathedral. His mother Mary (1763–1832) was the daughter of William Heberden (1710–1801). His father had inherited the Bottisham Hall property on the death of his distant cousin Soame Jenyns (1704–1787).

In 1817 Jenyns was introduced to Sir Jose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percichthys Melanops
''Percichthys melanops'' is a species of temperate perch endemic to Chile, where it occurs in pre-Andean streams. This species can reach TL. ''P. melanops'' was classified as an endangered species of Chile by Campos et al. (1998). It is listed as critically endangered by the International Union for Conservation of Nature due to a presumed range-wide population decline of 90% between 2011 and 2021. It is considered to be extirpated from the Aconcagua River basin. Threats to the continued existence of this sensitive species include rapid human development of watersheds and river courses and droughts associated with climate change Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system.
