ARGENTINA More than 320 million years ago, Patagonia was a separate continent that collided into Gondwana at the same time as Chilenia—present day Chile, according to scientists from the University of Buenos Aires. After conducting field tests in paleomagnetism, the researchers concluded that the deformations found along the southwestern margin of the Gondwana continent were … Continue reading Endangered deer have rebounded in Patagonia, Chevron allowed to resume drilling offshore Brazil, and new research says Patagonia was a separate continent.
ARGENTINA Argentina’s National University of Río Cuarto has developed an inoculant that hopes to improve sunflower growth under drought conditions. The technology consists of strains of the soil bacteria Bacillus pumilus (SF3 and SF4) and the endophytic (living in the plant) bacteria Achromobacter xylosoxidans (SF2) isolated from sunflowers under drought conditions. After fermenting these bacteria … Continue reading Pronghorns making a comeback in Mexico, pterosaurs in Brazil, and praying for dryland in Panama.
ARGENTINA Diabrotica, better known as the corn rootworm, is a pest beetle that causes major losses in the corn crop. Because the larvae develop underground, root growth is hindered and yield is affected. To control the pest, researchers have developed Diabrotica-resistant transgenics and rotated crops to disrupt their lifecycle. Scientists from the University of Buenos … Continue reading Controlling corn pests in Argentina and Mexico, the coffee growers’ strike in Colombia, and orcas beached off Chile’s Patagonia coast.
ARGENTINA Argentine scientists have identified hotspots of mosquito breeding in the country’s northern provinces. The research is part of an effort to eliminate populations of the Aedes aegypti mosquito, famous in Latin America for carrying the dengue virus. Writing in the journal PLoS ONE, the researchers created a predictive map that outlined where mosquitoes were … Continue reading Mexico City taps into one of the world’s deepest aquifers, Peru’s hemorrhaging anchovy fishery and growing diverse crops in Bolivia.
Ending hunger in Latin America, Colombia declares a new natural park, and Chile studies pollution and commuters ARGENTINA An individual from a rare species of armadillo was found by scientists outside Bahia Blanca, Argentina, though it died soon after discovery. The pink fairy armadillo is the smallest species of armadillo and is seldom found in … Continue reading Thursday January 10
