“…Paired choice tests coupled with the Thurstone–Mosteller model allow also to quantify and model time variation in preferences (Böckenholt, 2002). For this purpose, we offered 2 (1 for each treatment) fresh dandelion ( Taraxacum officinale F. H. Wigg; Asterales: Asteraceae) leaves to grasshoppers and we offered 2 miner's lettuce plants (1 for each treatment) ( Claytonia perfoliata ) to katydids (Fernandez‐Arhex et al ., ; Fernandez‐Arhex et al ., ). The leaves were, or were not, sprinkled with 0.5 g of volcanic ash of 3 different particle sizes.…”

“…Volcanic ash could cause negative effects on some insects; its mortality by volcanic ash may be due to different phenomena such as: poisoning by ingestion, desiccation, chemical reactions at the level of insect cuticle and/or direct mechanical action (Buteler et al ., ; Fernández‐Arhex et al ., ; Masciocchi et al ., ).…”

“…Therefore, the vulnerability of insects and the possible impacts of ash are strongly influenced by environmental conditions. In low humidity and strong wind conditions, ash has greater negative effects on insect survival or fitness (Ebelling, ; Fields & Korunic, ; Stadler et al ., ; Fernandez‐Arhex et al ., , ). Is worth noting that low humidity and strong wind are features of the study area of this work.…”

“…Fernández‐Arhex et al . () suggested that grasshoppers living in a dry environment were able to obtain enough humidity from fresh leaves to compensate for the negative environmental effects caused by the combination of low humidity, strong winds and ash. Therefore, it is also important to perform preference tests to observe if the insect can discriminate between positive and negative stimuli (infer things that animals can perceive as harmful).…”

Cumulative effects of volcanic ash on the food preferences of two Orthopteran species

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 katydid, Burgilis mendosensis (Phaneropteridae), to the presence of volcanic ash in their food sources and how this reaction changed as a function of time, we conducted paired preference tests between clean leaves of their preferred host plant and leaves exposed to volcanic ash of different grain size. The behavioral response was measured as the rating on the Thurstonian preference scale of leaves with ash in relation to clean leaves. The results showed that the avoidance of volcanic ash increased as a function of time in both species. Both species studied are occasionally exposed to volcanic activity, and come from an area in which a volcanic eruption had recently occurred. As their populations did not decrease after the ash fall, we propose that some behavioral responses such as avoidance of places with ash, works as tolerance mechanism to inert dusts exposure.

Total devastation of river macroinvertebrates following a volcanic eruption in southern Chile

Although explosive volcanic eruptions are natural disturbances that cause significant environmental repercussions and impose multiple changes on ecosystems, post-eruption studies of rivers and streams are not common. The most recent eruption of the Puyehue-Cord on Caulle volcanic complex (PCCVC) began on 4 June 2011 with a large explosion and the emission of a column of gas and volcanic ash (particle size <0.001-2 mm) followed by the release of silica magma, and lasted approximately until June 2012. The wind-dispersed volcanic ash affected the area surrounding the PCCVC in southern Chile and, subsequently, most of South America, but local effects on streams and rivers in the vicinity were more drastic. We collected water, ash, and benthic macroinvertebrate samples four months after the eruption from four rivers: Two were visibly impacted (Gol-Gol and Nilahue) in areas where volcanic ash thickness ranged between 1 and 5 cm, in the vicinity of the PCCVC fissure (8-15 km), and two adjacent rivers (Calcurrupe and Chanleufu) were located 20-40 km from the PCCVC fissure where ash thickness was <1 cm and did not present visible impacts. Results were then compared with data obtained from previous research projects. This study reports that this natural disaster induced an increase in concentrations of total suspended solids and of phosphorous in the rivers Gol-Gol and Nilahue, as well as habitat destruction, deterioration of environmental quality, and the consequent devastation of macroinvertebrate assemblages inhabiting these rivers directly following the eruption. We conclude that volcanic eruptions can generate local extinctions of benthic macroinvertebrates in the short term, compared with rivers that were not affected by volcanic ash.

Consequences of volcanic ash deposition on the locomotor performance of thePhymaturus spectabilislizard from Patagonia, Argentina

The locomotor performance of lizards depends on their morphological and physiological adaptations to the habitat. However, when the habitat changes dramatically, for example, by a volcanic eruption, the performance of lizards may be affected. We registered the vegetation cover, the surface covered by ash, the presence of crevices suitable for Phymaturus and the rocks slopes to analyze the effects of ash accumulation produced by the eruption of Puyehue-Cordon Caulle volcanic complex on microhabitat use and availability of the Phymaturus spectabilis lizard. In addition, we studied the effect of ashes and slope on the locomotor performance of P. spectabilis by registering the maximum speed in sprint runs and long runs under four different treatments (cork and on the level, ashes and on the level, cork and slope, and ashes and slope). P. spectabilis selected microhabitats unvegetated, with crevices and steep slopes. Regarding locomotor performance, the speed of lizards was negatively affected by the presence of ash only in sprint runs on the level and in long runs with slope. The slope had a negative impact on the speed in all the treatments. These results show that the presence of volcanic ashes in the substrate might have affected the locomotor performance of the lizards, especially in long runs, and hence, the interaction of individuals with the environment, that is, escaping from predators and social behavior.
