abstract = "Considering that plant phenology studies allow establishing
relationships between phenological patterns of vegetation and
changes caused by climate variability, the aim of this study was
to obtain phenological metrics for the predominant grassland
typologies in Rio Grande do Sul State, Brazil (latitudes 27º 05
and 33º 45 S and longitudes 49° 43 and 57º 39 W) and to evaluate
the spatial-temporal distribution pattern of these metrics under
the influence of the subtropical climate variability. The
phenological metrics were obtained based on the time series of the
EVI (Enhanced Vegetation Index), of the sensor MODIS (Moderate
Resolution Imaging Spectroradiometer), for the period from 2001 to
2014, through the Timesat program. Eleven phenological metrics
were extracted, identifying the presence of two spatial
distribution patterns of grass-dominated typologies in the Rio
Grande do Sul state, Brazil, one located in the south-central
region and the other located in the northeast, along the coast and
in the western portion of the state. In addition, it was also
observed that the phenological pattern of the grassland vegetation
of the state of Rio Grande do Sul, Brazil, is controlled by the
seasonality of vegetation, mainly associated with the variations
in air temperature.",
