Impact of volcanic ash deposition on foliar productivity and insect herbivory in northern Patagonia deciduous forests
(Asociación Argentina de Ecología, 2014)
Rising from the ashes: Changes in salmonid fish assemblages after 30 months of the Puyehue-Cordon Caulle volcanic eruption
(Elsevier Science, 2016-01-15)
Events such as volcanic eruptions may act as disturbance agents modifying the landscape spatial diversity and increasing environmental instability. On June 4, 2011 the Puyehue-Cordon Caulle volcanic complex located on Chile ...
Measurements and modeling of snow albedo at Alerce Glacier, Argentina: effects of volcanic ash, snow grain size and cloudiness
(Copernicus Publications, 2020-12)
The relevance of light absorbing impurities in snow albedo (and its effects in seasonal snow or glacier mass balance) have been under study for several decades. However, the effect of volcanic ash has been much less studied, ...
Desgaste dentario en ovinos Merino de la Patagonia Argentina, tras la erupción en Chile del Volcán Puyehue
(2015-07-25)
Tras la erupción en Chile del complejo volcánico Puyehue-Cordón Caúlle, el 4 de junio de 2011 se trabajó con 13 carneros Merino adultos de 3 y 4 años de edad a los cuales se los mantuvo a campo en un potrero de 8,1 hectáreas ...
Impact of Chaitén Volcano ashfall on native and exotic fish recovery, recolonization, and abundance
(Elsevier, 2021-01)
The effects of volcanic disturbance on aquatic communities and their recovery are poorly studied. To fill this gap, we explored the effects on fish communities in rivers in Argentina of the 2008 eruption of Chaitén Volcano ...
Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash
(Frontiers Media SA, 2020-01-14)
Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking ...
Effect of volcanic ash over Orthoptera survival in Patagonia
(2015-04)
The aim of this work was to evaluate the ash toxicity from the Puyehue-Cordón Caulle volcanic
complex on the survival of two Orthopteran species: the grasshoper Dichroplus vittigerum and the green locust
Brugilis sp. Two ...
Soil changes associated with land use in volcanic soils of Patagonia developed on dynamic landscapes
(Elsevier Science, 2018-07)
This paper aimed to identify indicators of soil degradation in volcanic soils developed in the ecotone between the Andean Forests and the Patagonian steppe. The study area is located in the Percy River Basin, Argentine, ...
INFLUENCE OF PARTICLE SIZE ON 31P-NMR ANALYSIS OF EXTRACTS FROM VOLCANIC ASH-DERIVED SOILS IN CHILE
