In the steppes of southern Chile, a commonly used management strategy for vegetation includes clear-cutting strips of shrubs in order to maximize the growth of forage plant species for sheep ranching. The Lesser Rhea (Rhea pennata), an endemic, flightless bird species categorized as "vulnerable" is an inhabitant in these ecosystems. The aim of the study was to determine the relationship between vegetation variables and habitat preferences of Lesser rheas in sites with and without this shrubland management. Lesser Rheas were found to prefer sites with medium level disturbance of shrubs and avoided control site (without management). Habitat preferences of a determinated management unit could be explained because the resulting habitat type provides shelter and food supplies simultaneously. These results suggest that maintaining medium cover of shrubs is an action that favorably affects rhea populations, but it is necessary to evaluate the spatial design of clear cutting as well.

“…Diciembre también presentó un promedio 1,6° C bajo su valor medio habitual, valor similar al obtenido para este mes en el 2000 (Butorovic 2001). Si bien los promedios invernales fueron mayores a los habituales, fueron las bajas temperaturas del verano, enero y febrero, las que hicieron que el promedio anual esté por debajo del promedio histórico de Punta Arenas.…”

The Influence of Synoptic Weather Types and Moisture Transport Pathways on Precipitation Isotopes in Southern Patagonia

We analyzed 28-year-long monthly oxygen isotope composition of precipitation (δ18Op) data from Punta Arenas (Chile) on the leeward side of the Andes to understand how different synoptic weather types and moisture transport pathways influence δ18Op variability in this region. Combining weather station 6 h precipitation data and atmospheric back trajectories, we found that in such a region where the atmospheric circulation pattern is dominated by very strong westerlies, an increased monthly proportion of easterly-delivered precipitation—with the air-mass trajectory path evading the influence of Andean “isotopic rain shadow” and having less rainout en route—would increase δ18Op. These synoptic easterlies are a result of quasi-stationary blocking-like flow that are an important but underappreciated part of regional circulation patterns and climate. In addition, synoptic easterlies are more often associated with heavy precipitation events as shown by weather station data and higher deuterium excess that indicates weaker post-condensation raindrop re-evaporation. Therefore, our analysis demonstrated the process link between the frequency of synoptic weather types characterized by blocking-like flow and temporal variations in δ18Op in Southern Patagonia. We conclude that isotope proxy paleo-records in this region could provide unique insights into the behaviors and dynamics of the large-scale Southern Hemisphere Westerly Winds over long timescales.
