The role of leaf cellulose content in determining host plant preferences of three defoliating insects present in the Andean-Patagonian forest
(2016)Los insectos fitófagos eligen sus recursos alimenticios según sus propias necesidades además de las propiedades de las plantas huésped, como las defensas biomecánicas. Las preferencias alimentarias de los insectos folívoros ... -
Lo rural y lo científico: La presencia de la Estación Experimental Regional Agropecuaria (EERA) INTA Bariloche 1962-1968
(Universidad Nacional de Quilmes, 2014-07)En este trabajo se discute el modo en que desde una práctica científica se toma lo rural en la estepa norpatagónica durante la segunda mitad del siglo XX, observando la intervención de estudios científicos asociados a la ... -

(Springer, 2020-09-20)Sarcocystis spp. are intracellular protozoan parasites with heteroxenous life cycles. This study described Sarcocystis spp. infection in adult South American native deer huemul (Hippocamelus bisulcus) and pudu (Pudu puda). ... -
Searching for molecular insight on hybridization in Nothofagus spp. forest at Lagunas de Epulauquen, Argentina = Estudio de la hibridación a nivel molecular en bosques de Nothofagus spp. en Lagunas de Epulauquen, Argentina
(2016)Los bosques en Lagunas de Epulauquen (36º49’S; 71º04’O) han sido considerados como la población más septentrional de Nothofagus obliqua en Argentina. En años recientes se ha cuestionado su verdadero estatus. La convergencia ... -
Seasonal diet of Lama guanicoe (Camelidae: Artiodactyla) in a heterogeneous landscape of South Patagonia = Dieta estacional de Lama guanicoe (Camelidae: Artiodactyla) en un paisaje heterogéneo de Patagonia Sur
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2013)Large diversity of habitat types, plant species assemblages, and silvopastoral activities in Nothofagus spp. forests condition the food availability for native herbivores. This work evaluates the seasonal diet of Lama ... -
Seed dormancy responses to temperature relate to Nothofagus species distribution and determine temporal patterns of germination across altitudes in Patagonia
(2015-08-26)Seeds integrate environmental cues that modulate their dormancy and germination. Although many mechanisms have been identified in laboratory experiments, their contribution to germination dynamics in existing communities ... -
Seed responses to temperature indicate different germination strategies among Festuca pallescens populations from semi-arid environments in North Patagonia
(Elsevier, 2019-04)Seed germination is one of the earliest phenotypes expressed by plants, and the accuracy to germinate in the correct time and place is essential for plant population fitness. Cues that regulate germination have been ... -
Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
(2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
