Seed dispersal by vertebrate frugivores plays an important role in plant population dynamics and community structure. The gut treatment may modify the germination response of seeds; often the specific effects of seed ...

The Antarctic peninsula and Patagonia region (South of South America) have recently been identified as one of the regions with the highest gravity wave activity in the world. In this work, the generation and propagation ...

The Antarctic peninsula and Patagonia region (the south of South America) have recently been identified as the regions with the highest gravity-wave activity in the world. In this work, the generation and propagation of ...

Studies about mobility, management of biotic and abiotic resources, exchange of material goods, ideas and information in hunter-gatherer societies, are a fundamental basis in order to discuss the socio-cultural dynamics ...

The existence of strong easterly winds down the western slope of the south-central Andes in Chile, locally known as Puelche winds, has been known by the meteorological community since at least the mid-twentieth century. ...

Above the southern Andes range and its prolongation in the Antarctic Peninsula, large-amplitude mountain and shear gravity waves observed with Weather Research and Forecasting (WRF) mesoscale model simulations during winter ...

This study analyzes tropospheric column ozone variability in the southern hemisphere as a function of ozone transport from the stratosphere to the troposphere and photochemical formation. Geographically, the study area was ...
