Phytoseiid mites (Acari: Phytoseiidae) from Patagonia and Tierra del Fuego.
Predatory phytoseiid mites have been intensively studied and surveyed in the last decades because of their economic importance as biocontrol agents of agricultural pests. However, many regions of the world remain unexplored and the diversity of the family worldwide is still fragmentary. Up to date no phytoseiid species have been collected in the southernmost part of the Earth down to latitude 4...
متن کاملLack of founding Amerindian mitochondrial DNA lineages in extinct aborigines from Tierra del Fuego-Patagonia.
Ancient DNA from bones and teeth of 60 individuals from four extinct human populations from Tierra del Fuego-Patagonia (Selknam, Yamana, Kaweskar and Aonikenk) has been extracted and the mitochondrial DNA (mtDNA) amplified by using the polymerase chain reaction. High-resolution analysis of endonuclease restriction site variation in the mtDNA and sequencing of its hypervariable non-coding contro...
متن کاملConference and Workshop Climate Impacts on Glaciers and Biosphere in Fuego-Patagonia
The Patagonian Icefields are among the highest latitude and most sensitive icefields in the Southern Hemisphere, and are responding sensitively to climate. Their response to rapid climate changes during the Last Termination and during Holocene palaeoclimatic fluctuations has the potential to elucidate changes in large scale atmospheric circulation as well as aid better predictions of their futu...
متن کاملEarly population differentiation in extinct aborigines from Tierra del Fuego-Patagonia: ancient mtDNA sequences and Y-chromosome STR characterization.
Ancient mtDNA was successfully recovered from 24 skeletal samples of a total of 60 ancient individuals from Patagonia-Tierra del Fuego, dated to 100-400 years BP, for which consistent amplifications and two-strand sequences were obtained. Y-chromosome STRs (DYS434, DYS437, DYS439, DYS393, DYS391, DYS390, DYS19, DYS389I, DYS389II, and DYS388) and the biallelic system DYS199 were also amplified, ...

© The Ecological Society of America www.frontiersinecology.org T first scientists to enter Amazonia encountered a wonderland of undescribed organisms living in what appeared to be unoccupied and untouched forest. Adjectives they used to describe the forest included “virgin”, “pristine”, and “timeless”, a vision which became incorporated into scientific thinking. Explanations of high Amazonian d...
