Aeolian Remobilisation of Volcanic Ash: Outcomes of a Workshop in the Argentinian Patagonia
(Frontiers Media, 2020-11-27)During explosive volcanic eruptions, large quantities of tephra can be dispersed and deposited over wide areas. Following deposition, subsequent aeolian remobilisation of ash can potentially exacerbate primary impacts on ... -
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 ... -
Assessing the magnitude of impact of volcanic ash deposits on Merino wool production and fibre traits in the context of a drought in North-west Patagonia, Argentina
(CSIRO Publishing, 2014-02)Environmental variability is a key feature of arid and semiarid rangelands worldwide. Drought is one of the main sources of variation in most extensive livestock production systems in arid environments, with biophysical ... -
First study of host-plant preferences of Sinopla perpunctatus (Hemiptera: Acanthosomatidae), a stink bug from the Andean-Patagonic forest
(Florida Entomological Society, 2014-06)Host plants of phytophagous insects are not equally attractive. The aim of this study was to evaluate the host-plant behavior of Sinopla perpunctatus Signoret (Hemiptera: Acanthosomatidae) and determine which parameters ... -
Immobilization and stabilization of volcanic ash in soil aggregates in semiarid meadows of Northern Patagonia
(Elsevier, 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 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 ...
