The climate of Patagonia: general patterns and controls on biotic processes

  title={The climate of Patagonia: general patterns and controls on biotic processes},
  author={Jos{\'e} M. Paruelo and Adriana B. Beltr{\'a}n and Esteban G. Jobb{\'a}gy and Osvaldo E. Sala and Rodolfo A. Golluscio},
In this article we review the main characteristics of the Patagonian climate, the spatial and temporal patterns of the most important climatic variables, and the influence of climate on ecosystem processes. The winter distribution of precipitation determines an asynchrony between the wet and the growing season in Patagonia. The amount of water that can be transferred from the wet season to the growing season depends mainly on the physical characteristics of the soil. In the semiarid steppe of… 

Long-term dynamics of water and carbon in semi-arid ecosystems: a gradient analysis in the Patagonian steppe

We used a soil water simulation model and remotely sensed data to study the long-term dynamics of transpiration, evaporation, drainage and net primary production across a precipitation gradient in

Regional aspects of streamflow droughts in the Andean rivers of Patagonia, Argentina. Links with large-scale climatic oscillations

Under the current global warming trend, droughts are expected to increase, with serious implications for water resources management. This study analyzed the regional aspects of droughts in terms of

Vegetation composition and its relationship with the environment in mallines of north Patagonia, Argentina

Abstract“Mallines” are characteristic Patagonian wet meadows. The objectives of this study were to describe plant community composition in the main mallines in northern Patagonia and to determine the

“Easterlies”‐induced precipitation in eastern Patagonia: Seasonal influences of ENSO'S FLAVOURS and SAM

The seasonal influence of the phases of El Niño‐Southern Oscillation (ENSO) and of Southern Annular Mode (SAM) on precipitation over eastern Patagonia is examined. Also, their impact in generating

Spatial and temporal variation of primary production of Patagonian wet meadows

Risks of Neglecting Phenology When Assessing Climatic Controls of Primary Production

We evaluated the effect that integrating annual aboveground net primary production (ANPP) along different 12-month periods has on temporal models of productivity (ANPP as a linear function of annual

Large-Scale Control on the Patagonian Climate

AbstractPatagonia, located in southern South America, is a vast and remote region holding a rich variety of past environmental records but a small number of meteorological stations. Precipitation

Climate variability and trends in the reproductive habitat of the critically endangered hooded grebe

The population of the critically endangered hooded grebe (Podiceps gallardoi) has decreased drastically during recent decades. The effects of climate change on their reproductive area (Southern

Eastern Andean environmental and climate synthesis for the last 2000 years BP from terrestrial pollen and charcoal records of Patagonia

Abstract. The Southern Hemisphere Westerly Winds (SWW) constitute an important zonal circulation system that dominates the dynamics of Southern Hemisphere mid-latitude climate. Little is known about



Precipitation and landscape related effects on soil moisture in semi-arid rangelands of Patagonia

Abstract The dynamics of soil water was evaluated in different landscapes during four growing seasons in a semi-arid grassland of Patagonia. At intervals of 60–90 days, the (gravimetric) soil

Primary Production of the Central Grassland Region of the United States

Aboveground net primary production of grasslands is strongly influenced by the amount and distribution of annual precipitation. Analysis of data collected at 9500 sites throughout the central United

Water losses in the Patagonian steppe: A modelling approach

In this paper we sought to answer questions related to the long-term soil water dynamics of the Patagonian steppe: What are the magnitude and seasonal dynamics of transpiration, evaporation, and deep

Differential use of large summer rainfall events by shrubs and grasses: a manipulative experiment in the Patagonian steppe

It is proposed that the generally reported poor response of deep-rooted shrubs to summer rainfalls could be because (1) the water is insufficient to reach deep soil layers, (2) the plants are in a dormant phenological status, and/or (3)Deep soil layers have a high water potential.

Environmental controls of NDVI dynamics in Patagonia based on NOAA‐AVHRR satellite data

. Variation in vegetation in extra-Andean Patagonia (Argentina) was analyzed using spectral data derived from AVHRR/NOAA satellite. The study of seasonal dynamics of the Normalized Difference

Phenology of Festuca pallescens in relation to topography in north‐western Patagonia

The sum of maximum air temperatures was identified as the environmental variable best correlated with the seasonal variation of phenological events of Festuca pallescens over the period of two growing seasons, explaining 93.2 % of the total variance.

Vegetation heterogeneity and diversity in flat and mountain landscapes of Patagonia (Argentina)

We studied floristic and diversity patterns and their environmental controls in two landscapes of contrasting to- pography in the Patagonian steppe. The analyses were focused on the effects of water

Regional climatic similarities in the temperate zones of North and South America

We performed an analysis of the climatic patterns of the temperate zones in North and South America using a global database of monthly precipitation and temperature. Three synthetic variables,


We analyzed the similarity of structural and functional characteristics of temperate grassland and shrubland ecosystems of North and South America. We based our analyses on correlative models that
