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 ... -
Food habits of Oligoryzomys longicaudatus (Rodentia) in a steppe–forest transitional area of Argentinean Patagonia
(Asociación Argentina de Ecología, 2014)We described the spatial and seasonal variation of feeding habits of Oligoryzomys longicaudatus in four environments of the steppe-forest transition zone of Argentinean Patagonia. Composition of fecal pellets collected ... -
Food partitioning between the Mara (Dolichotis patagonum) and the introduced hare (Lepus europaeus) in the Monte desert, Argentina
(Taylor & Francis, 1997)In the semiarid Monte desert, Río Negro province, the mara (Dolichotis patagonum) and the European hare (Lepus europaeus), which was introduced about hundred years ago, today occur sympatrically, as in many regions of ... -
Forage ofering and seasonal intake comparisons to evaluate European rabbit threat in Nothofagus forests of southern Patagonia
(Springer Nature, 2022-07-05)Background: The European rabbit (Oryctolagus cuniculus L. 1758) was introduced into diferent regions of the world, generating signifcant trade-ofs that critically impacted native vegetation. Here, we evaluate the rabbit’s ... -
Foraging behavior interactions between two non-native social wasps, Vespula germanica and V. vulgaris (Hymenoptera: Vespidae) : implications for invasion success?
(2016-01)Vespula vulgaris is an invasive scavenging social wasp that has very recently arrived in Patagonia (Argentina), a territory previously invaded – 35 yrs earlier – by another wasp, Vespula germanica. Although V. vulgaris ... -
Forest active restoration for silvopastoral use in Northwestern Patagonia: relative importance of the nurse effect
(Springer, 2023-03)Ecological interactions, such as facilitation among plant species, has been identified as key for restoration actions. The stress-gradient hypothesis predicts that facilitation increases under harsh environments, but ... -
From traditional knowledge to novel adaptations of transhumant pastoralists the in face of new challenges in North Patagonia
(Elsevier, 2018-10)Transhumant pastoralism is a mobile livelihood strategy in many mountainous, arid and semi-arid regions worldwide. The knowledge of pastoral communities and their lifestyle are strongly rooted in the historical evolution ... -
Functional farm household typologies through archetypal responses to disturbances
(Elsevier, 2020-02)Methods to construct farm household typologies may differ in their approach but they share a common feature: they rely mostly on structural farm data. Methods to build functional typologies are far less abundant. Households ... -

(Elsevier, 2023-09)Lymnaeid snails serve as intermediate hosts for Fasciola hepatica (Linnaeus, 1758), the etiological agent of fasciolosis, which is a widespread livestock disease in Argentina. Determining their geographic distribution and ... -
Genetic variation of leaf pigment content in a southern beech
(Springer, 2022-07)Leaf pigment concentration varied among populations, watersheds and between two consecutive years. The highest concentration of pigments was found in 2018, but both years showed the same trend among populations. Physiological, ... -
