Impact of overseeding cool-season annual forages on spring regrowth of tifton 85 bermudagrass
(Fundação Estudos Agrarios Luiz Queiroz (fealq), 2001-01-01)
Field observations have shown stand reduction and slow spring regrowth of Tifton. 85 bermudagrass (Cynodon spp.) pastures overseeded with temperate forages for grazing during the cool season. This experiment compared the ...
Summer precipitation variability over Southeastern South America in a global warming scenario
(Springer, 2012-05)
December–January–February (DJF) rainfall variability in southeastern South America (SESA) is studied in 18 coupled general circulation models from the WCRP/CMIP3 dataset, for present climate and the SRESA1B climate change ...
Effects of Shade on the Persistence of Cool Season Grasses to Form Turfgrass
(Instituto de Investigaciones Agropecuarias, INIA, 2007)
Recent changes in monthly surface air temperature over Peru, 1964–2014
(John Wiley and Sons Ltd, 2018-01)
This study assessed changes in the maximum and minimum surface air temperatures across Peru during the period 1964–2014. For this purpose, we employed the most complete records of air temperature series that were also ...
Seasonal variation in the phytoplankton of a saline lowland river (Buenos Aires, Argentina) throughout an intensive sampling period
(John Wiley & Sons Ltd, 2010-05)
The aim of this survey was to analyse seasonal variations in phytoplankton composition and abundance with respect to temperature and conductivity values at two sampling sites in the Salado River's lower basin: El Destino ...

(2015-10-02)
The toad, Rhinella schneideri, is a large-bodied anuran amphibian with a broad distribution over South America. R. schneideri is known to be active at night during the warm/rainy months and goes into estivation during the ...
Seasonality and reproductive periods of the hydroid Clytia gracilis in temperate littoral ecosystems. Is asexual reproduction the prime mechanism in maintaining populations?
(Taylor & Francis, 2011-11)
Hydropolyps inhabiting temperate ecosystems exhibit marked seasonality, and undergo regression as a normal part of their life cycle. In the campanulariid species Clytia gracilis, both hydroids and medusae are decidedly ...
