In the above-timberline zone of south-central Chile, stepped microtopography commonly develops on slopes of unstable volcanic ash deposits. Between the Nothofagus timberline and the high-altitude sparse fellfields, a scrubgrassland vegetation dominated by prostrate shrubs such as Empetrum rubrum and Pernettya spp. and tussock grasses such as Hierochloe utriculata and Cortaderia pilosa characteristically occurs on the stepped microtopography. Species interactions and species-microtopography… Expand

Vegetation Development on Deglaciated Rock Outcrops from Glaciar Frías, Argentina
Abstract The retreat of glaciers during past decades has led to the emergence of large rock outcrops in many glaciated areas around the world. Primary succession of vegetation in glacier forelandsExpand
Colonization of mid- and late-Holocene moraines by lichens and trees in the Magellanic sub-Antarctic province
TLDR
The colonization by lichens and vascular plants of two pro-glacial chronosequences encompassing the late- and mid-Holocene periods in the sub-Antarctic sub-region of South America is investigated to address questions related to the pattern of Magellanic forests recovery after disturbance and the applicability of lichenometry for developing glacier retreat chronologies.

Relationships between geomorphology and vegetation patterns in subantarctic Andean tundra of Tierra del Fuego
TLDR
Habitat variation associated with geomorphology played a major role in structuring vegetation in subantarctic Andean tundra (Tierra del Fuego, southern Argentina) and screes represent intermediate habitats where the ecotonal species Bolax gummifera colonises debris and/or basal rock and may enhance the establishment of vascular species.

Regional and local effects of disturbance and climate on altitudinal treelines in northern Patagonia
Abstract In this field study we analysed the regional and local scale effects of disturbance and climate on altitudinal treelines dominated by Nothofagus pumilio in northern Patagonia. We comparedExpand
Morphological and phenological differences in Nothofagus pumilio from contrasting elevations: Evidence from a common garden
TLDR
While these greenhouse-grown N. pumilio saplings showed heritable differences in plant architectural traits and leafing phenology, it was not clear how the genotypes characteristic of particular elevations would respond to longer growing seasons such as those predicted under global warming. Expand
Living on the edge: adaptive and plastic responses of the tree Nothofagus pumilio to a long-term transplant experiment predict rear-edge upward expansion
TLDR
This work evaluated the adaptive value of variation in quantitative traits of N. pumilio under contrasting conditions of the altitudinal gradient with a long-term reciprocal transplant experimental design, and suggested a relatively reduced potential for evolutionary adaptation of high-elevation genotypes, and a greater evolutionary potential of low-Elevation ones.

Structure and the Composition of Species in Timberline Ecotones of the Southern Andes
The subalpine southern Andean timberline is characterized by deciduous Nothofagus pumilio forests, which change with increasing altitude to Nothofagus krummholz, built of deciduous N. pumilio and N.Expand
Environmental v. genetically driven variation in ecophysiological traits of Nothofagus pumilio from contrasting elevations
TLDR
The results suggest that plants growing along elevational gradients may show complex ecophysiological patterns, which may be acquired by genetically driven responses to conditions that are fixed throughout the life span of individuals, such as soil nutrients. Expand
Urban airborne matter in central and southern Chile: Effects of meteorological conditions on fine and coarse particulate matter
Abstract Air pollution is one of the major global environmental problems affecting human health and life quality. Many cities of Chile are heavily polluted with PM2.5 and PM10, mainly in the coldExpand
