Un equipo internacional halla cambios sustantivos en la vida de los \u00e1rboles en las \u00faltimas tres d\u00e9cadas<\/strong><\/span><\/p>\n

La disminuci\u00f3n de la capa de ozono sobre las zonas polares afecta al crecimiento de los \u00e1rboles en esas regiones<\/strong>, seg\u00fan ha descubierto un grupo internacional de cient\u00edficos<\/span><\/p>\n

<\/span><\/p>\n

Un estudio de los bosques de la Patagonia argentina y chilena mostr\u00f3 que en las \u00faltimas tres d\u00e9cadas los \u00e1rboles sufrieron un retroceso sustantivo<\/strong> en su crecimiento.<\/span><\/p>\n

…….<\/span><\/p>\n

…….<\/span><\/p>\n

<\/span><\/p>\n

Desde que se detect\u00f3 el\u00a0agujero de ozono<\/a> hace 30 a\u00f1os, la tasa de crecimiento ha sido la m\u00e1s baja de l<\/strong>os \u00faltimos 600 a\u00f1os, seg\u00fan la investigaci\u00f3n publicada en la revista ‘Nature Geoscience’.<\/span><\/p>\n

……..<\/span><\/p>\n

……………<\/span><\/p>\n

<\/span><\/p>\n

Ante estos resultados, los cient\u00edficos decidieron investigar los anillos de los \u00e1rboles en otra parte del mundo -Australia y Nueva Zelandia<\/strong>– para averiguar si se registra un patr\u00f3n similar.<\/span><\/p>\n

………<\/span><\/p>\n

……..<\/span><\/p>\n

<\/span><\/p>\n

Con gran asombro hallaron lo contrario: los \u00e1rboles de las zonas extremas del sur han crecido a niveles m\u00e1s altos en las \u00faltimas tres d\u00e9cadas<\/strong>, desde aproximadamente el a\u00f1o 1700.<\/span><\/p>\n

<\/span><\/p>\n

Seg\u00fan el investigador principal Ricardo Villalba, del Instituto Argentino de Nivolog\u00eda, Glaciolog\u00eda y Ciencias Ambientales (IANIGLA), el fen\u00f3meno se relaciona con la variaci\u00f3n en el movimiento de vientos y, consecuentemente, precipitaciones y temperaturas, la llamada oscilaci\u00f3n ant\u00e1rtica. <\/strong><\/span><\/p>\n

<\/span><\/p>\n

Los investigadores creen que la\u00a0depleci\u00f3n de ozono<\/a> impact\u00f3 los ciclos de la oscilaci\u00f3n, prolongando la sequ\u00eda en una regi\u00f3n y lluvias en la otra. <\/strong><\/span><\/p>\n

An international team found substantial changes in the lives of the trees in the last three decades<\/span><\/p>\n

<\/span><\/p>\n

The decrease in the ozone layer over the polar regions affects tree growth in these regions, has discovered an international group of scientists<\/span><\/p>\n

<\/span><\/p>\n

————-<\/span><\/p>\n

<\/span><\/p>\n

A study of the forests of Patagonia, Argentina and Chile showed that in the last three decades the trees noun suffered a setback in its growth.<\/span><\/p>\n

…………..<\/span><\/p>\n

<\/span><\/p>\n

Since the ozone hole detected 30 years ago, the growth rate has been the lowest in the last 600 years, according to research published in the journal Nature Geoscience ‘.<\/span><\/p>\n

…………………..<\/span><\/p>\n

<\/span><\/p>\n

Given these results, the scientists decided to investigate the tree rings elsewhere in the world, Australia and New Zealand, to see if a similar pattern is recorded.<\/span><\/p>\n

……………..<\/span><\/p>\n

<\/span><\/p>\n

With great astonishment found the opposite: trees extreme southern areas have grown to higher levels in the past three decades, from about 1700.<\/span><\/p>\n

……………<\/span><\/p>\n

<\/span><\/p>\n

According to principal investigator Ricardo Villalba, the Argentine Institute of Snow Research, Glaciology and Environmental Sciences (IANIGLA), the phenomenon is related to the variation in the movement of winds and consequently rainfall and temperatures, the Antarctic Oscillation call.<\/span><\/p>\n

…………………..<\/span><\/p>\n

<\/span><\/p>\n

Researchers believe that the ozone depletion impact oscillation cycles, prolonging the drought in a region and rains in the other.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
