in North America. Volcanic activity in central Mexico

Study of the structural changes in the Popocatepetl volcano in Mexico related to microseismicity by applying the lineament analysis to the Aster (Terra) satellite data. Abstract Mexico is one of the most volcanically active regions in North America. Volcanic activity in central Mex-ico is associated with the subduction of the Cocos and Rivera plates beneath the North American plate. Periods of ...

Late Glacial Landscape Ecology in Central North America

The transition from full glacial to interglacial conditions along the southern margin of the Laurentide ice sheet resulted in dramatic changes in landscapes and biotic habitats. Strata and landforms resulting from the Wisconsin Episode of glaciations in the area directly west of Lake Superior indicate a context for late Pleistocene biota (including human populations) connected to ice margins, p...

Feeding Patterns of Tyrophagus putrescentiae (Sarcoptiformes: Acaridae) Indicate That Mycophagy Is Not a Single and Homogeneous Category of Nutritional Biology

Mycophagy should not be considered as a single and homogeneous category of nutritional biology due to the specific symbiotic chitinolytic bacteria associated with mites and fungi. To test interaction among mites, fungi, and chitinolytic bacteria, experiments were conducted on the model species Tyrophagus putrescentiae (Schrank). Mucor sp, Alternaria alternata, Penicillium claviforme, P. griseof...

Admixture in North America

The history of North America has been marked by the encounter of populations from different continents. The discovery of the New World began a period defined by human migrations at a much larger scale than in previous history. This movement of people, voluntary or forced, changed profoundly the human landscape. As populations came into contact, admixture followed in varying degrees depending on...
