Host plant choice and effect of temperature on feeding behaviour of Perzelia arda (Lepidoptera: Depressariidae), a leaf-tying larva, on Nothofagaceae from the Andean Patagonian forest
(Wiley, 2021-08)Environmental temperature may cause changes in the physiology and feeding behaviour of herbivorous insects and, consequently, in the damage they can cause. In the Andean Patagonian forest, an eco-region dominated by trees ... -

Integrating genetics and suitability modelling to bolster climate change adaptation planning in Patagonian nothofagus forests
(2017)We investigated the impact of past changes in habitat suitability on the current patterns of genetic diversity of two southern beeches (Nothofagus nervosa and Nothofagus obliqua) in their eastern fragmented range in ... -
Lack of genetic variation in natural populations of a Patagonian berry with nutraceutical properties [Conjunto de datos]
(2022)This table contains sequencing data of PCR-amplified DNA fragments of 6 SSR markers developed by Bastías et al. (2016). The markers chosen were M4, M9, M45, M32, M15 and M18. The amplified fragments were resolved on an ABI ... -
Long-term monitoring reveals the effect of precipitation and silviculture on Nothofagus regeneration in Northern Patagonia mixed forests
(Springer, 2024-04)Background: Tree regeneration is a key component of resilience because it promotes post-disturbance recovery of forests. Northwestern Patagonia from Argentina is occupied by Nothofagus alpina (Na), N. obliqua (No), and N. ... -
Looking at the forest from below: the role of seedling root traits in the adaptation to climate change of two Nothofagus species in Argentina
(2018-05)Global climate change (CC) is an evolutionary challenge for natural tree populations. Scientific experts forecast an increase in temperature and a decrease in precipitation in the Argentine Patagonian Cordillera. Knowledge ... -
Management of Nothofagus genetic resources: Definition of genetic zones based on a combination of nuclear and chloroplast marker data
(Elsevier, 2013-08-15)Development of appropriate forest conservation and management measures for a given tree species includes the identification of distinct genetically homogeneous units across its overall distribution range, which depends on ... -
El manejo leñero de los arbustales o bosques mixtos bajos en el N.O. Patagónico
(EEA Bariloche, INTA, 2021)Las comunidades vegetales pos fuego del NO de la Patagonia, constituidas preferentemente por especies como la laura (Schinus patagonicus), el retamo (Diostea juncea), el ñire (Nothofagus antárctica) y el radal Lomatia ... -
Manual de viverización, cultivo y plantación de Roble Pellín en el norte de la región Andino Patagónica
(Ediciones INTA, 2010)Las especies leñosas nativas de nuestros Bosques Andino-Patagónicos no sólo conforman parte de nuestro patrimonio natural, al cual debemos conservar, sino que además muchas de ellas se presentan como una alternativa ... -
Un marco ecológico para establecer márgenes de manejo de sistemas silvopastoriles. 1- El caso de ñirantales del norte de la Patagonia, Argentina
(Ediciones INTA, 2015-05-07)En bosques nativos bajo uso silvopastoril, el manejo tiene un fuerte impacto sobre la dinámica y estructura. Por ello, es necesario conocer sus efectos para diseñar prácticas de manejo que mantengan, en el largo plazo, al ... -
Mixed Nothofagus forest management: a crucial link between regeneration, site and microsite conditions
(Springer Nature, 2020)Canopy openings due to harvesting practices constitute a disturbance that changes the environmental conditions of microsites. Its impact on the relative performance of the regeneration of different tree species could also ... -
