“…The mean annual precipitation decreases from south to north, with lower values on the northern slopes of the massif (Baroni et al, 2004). Precipitation mostly occurs as snow, from November to May, and the total number of days per year with persistent snow cover can reach well over 200 (Baroni et al, 2007). In Fig.…”

“…Along the valley slopes, geomorphic processes, such as running water, debris flow and snow avalanches (and, in part, also debris/rock fall), are extremely active and concentrated in the ''central channel'' (i.e. composite channel), a unit of the ''composite alpine debris cones'' (Baroni et al, 2007). Such processes, along with altitudinal gradients, seem to influence the dispersal (of seeds, spores and propagules), colonization, spread and establishment of these species in the alpine corridors.…”

“…ring-width chronologies. As commonly found in the Alpine mountain environment, the investigated area is characterized by high-energy geomorphological processes affecting tree vegetation, which is frequently subjected to diverse growing disturbance factors such as avalanches and mass wasting movements (Baroni et al, 2007;Gentili et al, 2010). Therefore, sampling was conducted in the open forest below the treeline selecting dominant and undisturbed trees without stem or crown anomalies potentially biasing the climatic signal (e.g.…”

Abstract. Climate records from remote mountain sites and for century-long periods are usually lacking for most continents and also for the European Alps. However, detailed reconstructions of climate parameters for pre-instrumental periods in mountain areas, suffering of glacial retreat caused by recent global warming, are needed in the view of a better comprehension of the environmental dynamics. We present here the first annually-resolved reconstruction of summer (JJA) mean temperature for the Adamello-Presanella Group (Central European Alps), one of the most glaciated mountain groups of the Italian Central Alps. The reconstruction has been based on four larch tree-ring width chronologies derived from living trees sampled in four valleys surrounding the Group. The reconstruction spans from 1610 to 2008 and the statistical verification of the reconstruction demonstrates the positive skill of the tree-ring dataset in tracking summer temperature variability also in the recent period.

“…Por outro lado, o tipo de vegetação existente está diretamente relacionado com a geomorfologia local (Hupp & Osterkamp, 1985;Hupp & Osterkamp, 1996) e pode ser utilizado como um bom indicador das formas fluviais quaternárias (e.g. Casco et al 2005;Baroni et al, 2007). Outros elementos decorrentes de erros intrínsecos do MDE-SRTM são feições lineares com ganho altimétrico, orientadas 45ºNE, que podem ser observadas na região nordeste do MDE-SRTM processado (Figura 5-A) e não expressam componentes fisiográficos ou geomorfológicos.…”

ResumoMegaleques são sistemas fluviais distributários com extensão superficial da ordem de 10 3 a 10 5 km 2 . Tais sistemas compõem a maior parte do trato deposicional do Pantanal Mato-grossense. Dentre eles se destaca o megaleque do Taquari, com área aproximada de 49.000km 2 e superfície caracterizada pela presença de complexa rede de canais e paleocanais distributários e de formas deposicionais com geometria lobada. Análise baseada no processamento de dados SRTM foi realizada com o objetivo de mapear as redes de drenagem distributária e as formas deposicionais. Com base em modelos digitais de elevação, dez paleo-redes de drenagem distributária foram reconhecidas na superfície do megaleque do Taquari, todas elas constituindo formas deposicionais de geometria lobada altimetricamente mais altas que seu entorno. A identificação destes elementos deposicionais é passo inicial para a reconstituição de eventos de construção e abandono de lobos, bem como para a previsão de futuras mudanças no curso do rio Taquari.Palavras-chave: megaleque fluvial, geomorfologia fluvial, modelo digital de elevação. AbstractMegafans are large fluvial distributary systems with areal extent varying from 10 3 to 10 5 km 2 . Fluvial megafans are the main depositional system in the Brazilian Pantanal wetland, being the Taquari megafan the most remarkable of them covering an area of approximately 49.000 km 2 . Distributary drainage networks and depositional lobes are major geomorphic features on the Taquari megafan surface. In this study, digital elevation models (DEM) based on remote sensing were used to identify and
