| Glacial erosion and sediment production are of interest to diverse scientific communities concerned with the interaction of climatic, tectonic and surface processes that influence the evolution of orogens and with the climatic signals archived in glacigenic strata. We review the current state of knowledge on the generation, transfer, and accumulation of glacigenic sediment from land to sea. We draw from geomorphology, marine geology, geochronology, numerical modeling of surface processes and landscape evolution, and experimental and field observations of glacier erosion and deposition, and the interaction of ice with its bed and the ocean boundary. Our primary goal is to examine glacial systems using a holistic source-to-sink approach, with a focus on... |

| The northernmost 'robles' of Argentina, located in Lagunas de Epulauquen (northwest Patagonia), are considered a population of Nothofagus obliqua, even though they differ in some respects from individuals of other populations of the species. In order to analyse a possible genetic basis of their distinctive character, we revised previous information and added new evidence based on biochemical (isozyme) and molecular (chloroplast DNA and nuclear microsatellite) markers, as well as quantitative trait variation (seed traits, leaf morphology, plant architecture and field performance). The comparison of Lagunas de Epulauquen specimens with specimens from other areas in Argentina demonstrated their genetic distinction. Glacial history, in conjunction with... |
