Sarcocystis spp. infection in South American deer huemul (Hippocamelus bisulcus) and pudu (Pudu puda) from Patagonian National Parks, Argentina
(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). ... -
Sauce criollo (S. Humboldtiana)
(EEA Bariloche, INTA, 2017)En el mundo hay alrededor de 400 especies de sauces, casi todos crecen en el hemisferio Norte. Salix Humboldtiana es la única especie que llega en su distribución natural hasta Sudamérica, extendiéndose desde México hasta ... -
Screening for swainsonine among South American Astragalus species
(2017)Swainsonine is a toxic alkaloid found in several plant genera worldwide. The objective of this study was to screen several South American Astragalus species for the toxin swainsonine. Swainsonine was detected in 16 of 30 ... -
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 ... -
Securing water for trees and people : possible avenues
(2011)In the context of water scarcity, threats on forest survival in drier areas, and thus of inevitable trade-off between man and nature for the use of water, this section addresses three main questions of importance for ... -
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 ... -
Seeding Resilient Restoration: An Indicator System for the Analysis of Tree Seed Systems
(MDPI, 2021-08-09)Achieving multi-million-hectare commitments from countries around the world to restore degraded lands in resilient and sustainable ways requires, among other things, huge volumes of tree planting material. Seed systems ... -
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 ... -

Servicio de entrenamiento en técnicas reproductivas en rumiantes menores: una experiencia de 30 años que continúa. Comunicación
(Asociación Argentina de Producción Animal, 2022-11)Desde el año 1990, el Grupo de Reproducción y Genética del INTA Bariloche ha realizado, en forma continua, cursos de entrenamiento en técnicas reproductivas para ovinos y caprinos en las temáticas de congelamiento seminal, ... -
Severity of impacts of an introduced species corresponds with regional eco‐evolutionary experience
(John Wiley & Sons Ltd, 2018-09)Invasive plant impacts vary widely across introduced ranges. We tested the hypothesis that differences in the eco-evolutionary experience of native communities with the invader correspond with the impacts of invasive species ... -
Sex, life history and morphology drive individual variation in flight performance of an insect parasitoid
(2017-08)1. The movement of organisms can be driven by multiple factors and has implications for fitness and the spatial distribution of populations. Insects spend a large proportion of their adult lives foraging by flying for ... -
Sex-related difference in susceptibility to cypress mortality in Austrocedrus chilensis from Northwestern Patagonia (Argentina) = Susceptibilidad diferencial al mal del ciprés entre sexos de Austrocedrus chilensis en la Patagonia (Argentina)
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2012)Female and male individuals of dioecious species have different reproductive functions and sex-related differences have been reported in growth rate, age at maturity, size, spatial distribution and physiological responses ... -
Shaping forces modelling genetic variation patterns in the naturally fragmented forests of a South-American Beech
(Elsevier, 2009-10)Fourteen natural populations of the South-American Beech Nothofagus obliqua at the Eastern naturally fragmented area of its distribution range were subjected to genetic analysis using genetic markers. The genetic ... -
Short-term energy supplementation before lambing improves maternal behaviour, udder volume, colostrum viscosity and lamb birthweight in ewes under extensive grazing
