Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms.
Rapoport's rule is an ecogeographical rule that states that latitudinal ranges of plants and animals are generally smaller at lower latitudes than at higher latitudes.
The National Atomic Energy Commission is the Argentine government agency in charge of nuclear energy research and development.
In biogeography, a cosmopolitan distribution is the range of a taxon that extends across most or all of the surface of the Earth, in appropriate habitats; most cosmopolitan species are known to be highly adaptable to a range of climatic and environmental conditions, though this is not always so. Killer whales (orcas) are among the most well-known cosmopolitan species on the planet, as they maintain several different resident and transient (migratory) populations in every major oceanic body on Earth, from the Arctic Circle to Antarctica and every coastal and open-water region in-between. Such a taxon is said to have a cosmopolitan distribution, or exhibit cosmopolitanism, as a species; another example, the rock dove, in addition to having been bred domestically for centuries, now occurs in most urban areas around the world.
Neuquenornis volans is a species of enantiornithean birds which lived during the late Cretaceous period in today's Patagonia, Argentina. It is the only known species of the genus Neuquenornis. Its fossils were found in the Santonian Bajo de la Carpa Formation, dating from about 85-83 million years ago. This was a sizeable bird for its time, with a tarsometatarsus 46.8mm long. Informal estimates suggest that it measured nearly 30 cm (12 in) in length excluding the tail.
Rhamnus cathartica, the European buckthorn, common buckthorn, purging buckthorn, or just buckthorn, is a species of small tree in the flowering plant family Rhamnaceae. It is native to Europe, northwest Africa and western Asia, from the central British Isles south to Morocco, and east to Kyrgyzstan. It was introduced to North America as an ornamental shrub in the early 19th century or perhaps before, and is now naturalized in the northern half of the continent, and is classified as an invasive plant in several US states and in Ontario, Canada.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
Neuquensuchus is an extinct genus of crocodyliform from the Santonian-age Upper Cretaceous Bajo de la Carpa Formation of Neuquén Province, Argentina. The known remains were discovered on the campus of Universidad Nacional del Comahue in the city of Neuquén. Neuquensuchus was named by Lucas E. Fiorelli and Jorge O. Calvo in a publication dated to 2007, but which became available in 2008. The type species is N. universitas, in recognition of its discovery locality. Unlike the great majority of crocodyliforms, its shin was longer than its thigh, suggesting it had some running ability.
The National University of Comahue is an Argentine national university with branches in the provinces of Neuquén, Río Negro and Chubut, with a centre in the city of Neuquén and units in Viedma, Bariloche, San Martín de los Andes, Cipolletti, Zapala, Allen, General Roca, Choele Choel, San Antonio Este, Villa Regina, Esquel, Puerto Madryn and Trelew. It is the largest public university in Argentine Patagonia.
Guerra a muerte is a term coined by Benjamín Vicuña Mackenna and used in Chilean historiography to describe the irregular, no-quarter warfare that broke out in 1819 during the Chilean War of Independence.
Springtails form the largest of the three lineages of modern hexapods that are no longer considered insects. Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts.
Silvia N. Blumenfeld is an expert on mycology. From 1986 to 2004, she was a Professor of Mycology and Biotechnology of Filamentous Fungi at the National University of Comahue, in Río Negro, Argentina. She emigrated to Israel in 2002, where she became the curator of the Tel Aviv University fungi collection, specializing in medicinal mushrooms. She has over 50 articles, books, and patents to her name, and has received academic honours. In 1995, she was awarded the Argentine National 'José Antonio Balseiro' Prize for her work.
Microbial biogeography is a subset of biogeography, a field that concerns the distribution of organisms across space and time. Although biogeography traditionally focused on plants and larger animals, recent studies have broadened this field to include distribution patterns of microorganisms. This extension of biogeography to smaller scales—known as "microbial biogeography"—is enabled by ongoing advances in genetic technologies.
Samuel James is an American scientist, a researcher specializing in evolutionary biology, focusing on earthworm taxonomy. James, with fellow researchers, has discovered numerous species of annelids, including Diplocardia californiana, Diplocardia woodi, Diplocardia montana, and a new species related to the Giant Palouse earthworm.
Hypochaeris chillensis also known as Brazilian cat's ear is a species of flowering plant in the family Asteraceae. It is native to South America but has become naturalized in parts of North America, South Africa. and Taiwan. It is a common and widespread weed in the Southeast United States.
José Luis Castro Aguirre was a Mexican ichthyologist. He was a founding member of the Mexican Ichthyological Society and a member of the National System of Investigators who produced around 150 publications, focusing chiefly on the taxonomy, ecology, and biogeography of the fishes of Mexico. His 1978 book Catálogo sistemático de los peces marinos que penetran en aguas continentales de México, con aspectos zoogeográficos y ecológicos was the first catalog of estuarine fishes of Mexico. Born in Mexico City, he attended the National School of Biological Sciences at the National Polytechnic Institute (ENCB-IPN) earning a master's degree in 1974 and a PhD in 1986. He worked at the National Fisheries Institute and the Food and Agriculture Organization in the 1960s, and later was professor and researcher at the ENCB-IPN, Universidad Autónoma Metropolitana, the Interdisciplinary Center of Marine Science and Northeast Center of Biological Research. He described around a dozen fish species, including several species of shark. A book of research papers in his honor was produced in 2012, and he was posthumously commemorated in the names of the fish species Hypoplectrus castroaguirrei and Eugerres castroaguirrei.
Martín Daniel Ezcurra is an Argentine palaeontologist naming many extinct genera such as Aerotitan, Lophostropheus and Powellvenator.
Rafael Jordana Butticaz is a Spanish scientist, Emeritus Professor of Animal Physiology and Zoology, and specialist in springtails (Collembola).
The School of Languages (FADEL) is one of the 17 schools that constitute the National University of Comahue in Argentina. It is located in General Roca, province of Río Negro (Mendoza and Perú). It has 800 students, but with the Department of Foreign Languages for Specific Purposes (DIEPE), located in the city of Neuquén, it provides services to the over 35,000 active students attending its courses in any of the 76 undergraduate and postgraduate programs offered in the different academic units in the provinces of Río Negro and Neuquén.
Pyotr Petrovich Vtorov was a Soviet scientist biogeographer, ecologist, zoologist and nature conservation activist. He founded a new direction of scientific research called Synthetic Biogeography, and developed a scientific concept for the creation of reference areas of the biosphere. He was an author of textbooks, a guide to birds, scientific and popular books.
