Impact of forest fire ash on surface charge characteristics of andisols
(LIPPINCOTT WILLIAMS & WILKINS, 2007)
Forest fires are a common occurrence in central southern Chile where soils are mostly Andisols. The ash deposits may alter the chemical properties of the soils in the burned areas and nearby agricultural lands. In a column ...
Sustained effects of volcanic ash on biofilm stoichiometry, enzyme activity and community composition in North- Patagonia streams
(Elsevier, 2018-04-15)
Volcanic eruptions are extreme perturbations that affect ecosystems. These events can also produce persistent effects in the environment for several years after the eruption, with increased concentrations of suspended ...
Immobilization and stabilization of volcanic ash in soil aggregates in semiarid meadows of Northern Patagonia
(Elsevier Science, 2021-06-15)
Although volcanism may be perceived by the society as a phenomenon with mostly negative consequences, this is not always the case especially for natural systems. There is a limited knowledge on how the deposited pristine ...
The effect of volcanic ashes of Cordon Caulle on soil physical quality parameters in agricultural soils of southern ChileEfecto de cenizas volcánicas del Cordón Caulle sobre parámetros de calidad física en suelos agrícolas del sur de Chile
(Facultad de Ciencias Agrarias. Universidad Austral de Chile, 2015)
Cumulative effects of volcanic ash on the food preferences of two Orthopteran species
(Wiley Blackwell Publishing, Inc, 2017-08)
Inert dusts are an early form of insecticide which is still in use. One of the most common inert dusts is volcanic ash. In order to study the reaction of rangeland grasshoppers, Dichroplus vittigerum (Acrididae) and a ...
The effects of volcanic ash from Puyehue-Caulle range eruption on the survival of Dichroplus vittigerum (Orthoptera: Acrididae)
(2013-03)
The aim of this work was to evaluate the toxicity of volcanic ash from the volcanic complex Puyehue-Caulle Range on the grasshopper, Dichroplus vittigerum, and compare the results with the effect of diatomaceous earth, an ...
Multivariate factorial analysis to design a robust batch leaching test to assess the volcanic ash geochemical hazard
(Elsevier Science, 2012-04-07)
A method to obtain robust information on short term leaching behaviour of volcanic ashes has been developed independently on the sample age. A mixed factorial design (MFD) was employed as a multivariate strategy for the ...
Actividad del volcán Sabancaya (Perú) 2016-2017: observaciones petrográficas y geoquímicas de los depósitos de tefras del 2017
(Presses universitaires Blaise PascalFR, 2018-04)
From 2013 to present-day, the Sabancaya volcano has resumed a new eruptive episode that we have subdivided in two phases: the first phase was characterized by degassing; coincided with the occurrence of five fumarolic vents ...
Ashes in the air : the effects of volcanic ash emissions on plant-pollinator relationship and possible consequences for apiculture
(2013-05)
El rendimiento de forrajeo de los polinizadores podría ser alterado por las flores de cenizas volcánicas contaminados, polen y néctar. Se utilizó la abeja melífera (Apis mellifera) como organismo modelo para comprender los ...
