Plant fire ephemerals are well-adapted to fire-prone environments, with germination strategies linked fire-related cues like smoke. Germination requirements in Patagonian poorly studied, no research on the effects of smoke water (SW) and isolated karrikinolide (KAR) their germination. We assessed responses two native ephemeral herbs, Boopis gracilis, Nicotiana linearis, SW KAR1 at three concentrations (1/100, 1/1000, 1/10000) a Control (no or KAR1). Seeds collected different harvest dates...
Abstract Question: (1) Which factors regulate post‐fire recruitment and spread of the shrub Senecio bracteolatus in Patagonian grasslands? (2) What is role grass Stipa speciosa on S. establishment succession? Location: Northwest Patagonia, Argentina. Methods: We studied effect fire density by comparing these variables between burned unburned grasslands. In areas, we compared abiotic characteristics seedling under canopy grasses ( ) gaps (inter‐tussock areas). Post‐fire interactions seedlings...
Abstract Aims Changes in land cover resulting from the introduction of non‐native pine plantations and subsequent invasion is increasingly affecting forest areas Southern Hemisphere, having negative impacts on diverse ecosystem components. We studied abundance, biophysical attributes, flammability litter temperate forests modified by Pinus radiata , later its post‐fire adjacent sites. also evaluated short‐term effects mechanical removal P. Location North‐western Patagonia, Argentina. Methods...
Abstract Fire affects grassland composition by selectively influencing recruitment. Some exotic species can increase their abundance as a consequence of fire‐stimulated seed germination, but response may depend on age. Rumex acetosella L. (Polygonaceae, sheep’s sorrel) is cosmopolitan herb that has invaded NW Patagonia’s grasslands. This forms persistent soil banks and increases after disturbances, particularly fire. We studied how fire longevity influence R. germination. In 2008, we...
Background Global change produces pervasive negative impacts on biodiversity worldwide. Land use and biological invasions are two of the major drivers global that often coexist; however, effects their interaction natural habitats have been little investigated. In particular, we aimed to analyse whether invasion an introduced grass ( Bromus tectorum ; cheatgrass) along roads verges disturbance level in surrounding habitat interact influence degree B. latter north-western Patagonia. Methods...
Abstract Livestock can affect the soil seed bank through various mechanisms associated with changes in vegetation. We sampled vegetation and banks of P atagonian grasslands, areas different historical use by grazing (exclosure, moderate high use) to evaluate what extent are reflected bank. also evaluated effect on horizontal spatial distribution sampling under shrubs between plant gaps. focused study functional groups, palatable oa ligularis , an indicator grassland status. In general,...
Biological invasions are considered a major problem for nature conservation globally. Natural resource managers make immense efforts to control invasions. However, many management strategies depend on public support. In this study, we assessed how recreational users perceive the level of protected area where native forest has been altered by introduction fire-adapted Pinus radiata, wildfires and resulting invasion. We also analyzed users’ definition exotic species related their perceptions...
