Genetic control of the tree-ring response of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) to the 2003 drought and heat-wave in France
(Springer, 2008)The genetic control of tree ring growth in Douglas-fir in response to the drought and heat-wave that occurred in 2003 in Europe was studied with microdensity profiles in three clonal experiments located in three different ... -
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, ... -
Hacia lógicas de resiliencia en innovaciones tecnológicas y gestión productiva de sistemas ganaderos extensivos en Patagonia, Argentina
(Centro Interdisciplinario de Estudios Agrarios, 2017-11)Las principales recomendaciones de manejo ganadero y pastoril en las últimas tres décadas en Patagonia estuvieron orientadas por lógicas basadas en la estabilidad y la eficiencia. Los mayores esfuerzos se centraron en la ... -
Heritable variation in the survival of seedlings from Patagonian cypress marginal xeric populations coping with drought and extreme cold
(Springer, 2012-01)The rear edges of tree species have begun to be perceived as highly valuable for genetic resources conservation and management. In view of expected climatic changes, the responses of trees at their xeric limits may largely ... -
New world goat populations are a genetically diverse reservoir for future use
(Springer Nature, 2019-02-06)Western hemisphere goats have European, African and Central Asian origins, and some local or rare breeds are reported to be adapted to their environments and economically important. By-in-large these genetic resources have ... -
Sistemas ganaderos patagónicos : Desenfocando la mira en la productividad para enfocarnos en la adaptabilidad
(EEA Bariloche, INTA, 2020-12)En los últimos 15 años, eventos como la sequía, la caída de cenizas volcánicas y las grandes nevadas han impactado negativamente en los sistemas ganaderos de la Patagonia. Es momento de cambiar la manera de planificar la ... -
The impact of different natural environments on the regeneration dynamics of two Nothofagus species across elevation in the southern Andes
(Elsevier, 2020-05-15)A widely accepted paradigm in forest ecology proposes that patterns of relative abundance among mature forest trees are largely influenced by biotic and abiotic processes that operate most intensely during the earliest ... -
Variation of wood density and hydraulic properties of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) clones related to a heat and drought wave in France
(Elsevier, 2009-01)Drought response of three Douglas-fir clones (slow, intermediate and fast growing) inhabiting two different climatic regimes in France was examined.We used the hydraulic conductivity and the percent loss of conductivity ...
