Early 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, ...
متن کاملFuego: Middleware for Mobile Data Communication and Synchronization
In designing middleware for wireless mobile devices, the environment is notably different from its wired counterpart. Compared to fixed networks and hot-spots, wide-area wireless networks tend to offer lower bandwidth, and higher latency and pricing. The computing capabilities of devices are weaker, and every CPU cycle counts, as energy consumption is a key issue for making a device successful ...
متن کاملPhytoseiid 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 کاملSupervivencia Posterior al Emplumamiento de Ammodramus savannarum en Pastizales Manejados con Fuego y Pastoreo POSTFLEDGING SURVIVAL OF GRASSHOPPER SPARROWS IN GRASSLANDS MANAGED WITH FIRE AND GRAZING
More accurate estimates of survival after nestlings fledge are needed for population models to be parameterized and population dynamics to be understood during this vulnerable life stage. The period after fledging is the time when chicks learn to fly, forage, and hide from predators. We monitored postfledging survival, causespecific mortality, and movements of Grasshopper Sparrows (Ammodramus s...
متن کامل-Y, Y loss in leukemia
Note Loss of the Y chromosome from individual metaphases is common in metaphase cells from both PHAstimulated lymphocytes and spontaneously dividing bone marrow cells. The frequency of Y loss is greater in older men, and the size of the 45,X,-Y cell population probably increases gradually with advancing age. (In females, a corollary loss of one X chromosome also occurs with advancing age.) This...
