Perspectivas de estrategias para el manejo de la Chaqueta Amarilla
(EEA Bariloche, INTA, 2021-12)Las avispas “chaqueta amarilla” se encuentran bien establecidas en la Patagonia Argentina. Cada verano, cuando la abundancia de estas avispas comienza a ser alta, muchas actividades cotidianas al aire libre se ven afectadas ... -
Perspectives on Rangeland Management Education and Research in Argentina
(Society for Range Management, 2011-02)Rangelands account for over two-thirds of Argentina’s land area and contribute uniquely to its biodiversity, agricultural livelihood, and cultural identity. Colossal mountain ranges and regional air mass movements create ... -
Perspectives – Academic career in ecology: Effect of gender, caregiving labor, and the working environment
(Elsevier, 2024-05)True meritocracy is only fair when a leveled playing field is guaranteed. Scientists with caregiving responsibilities, often women, carry a heavy burden of unpaid labour, and therefore suffer downfalls in performance. ... -
Pest management of social insects in urban settings
(2017-04)Pest management of social insects in urban environments is a growing global concern, given the problems that these pests generate and the growth of urban areas worldwide. In this special issue, we present studies on the ... -
Pérdidas embrionarias y fetales en ovinos
(Universidad Nacional de La Plata, 2016)En los ovinos las pérdidas reproductivas pueden ser clasificadas según el momento de su ocurrencia en: fallas en la fertilización, muertes embrionarias y/o fetales, y muertes perinatales. Las pérdidas acontecidas durante ... -
Pérdidas reproductivas de la preñez según el estado nutricional materno en ovejas Merino
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata, 2020)La producción ovina en el norte de la Patagonia Argentina contempla principalmente sistemas de cría en condiciones extensivas estratificados en productores de baja y media escala de producción, variando la composición de ... -
Phases or regimes? Revisiting NDVI trends as proxies for land degradation
(Wiley, 2018-03)One of the main challenges in land degradation assessment is that a rigorous and systematic approach to addressing its complex dynamics is still missing. The development and application of operative tools at regional and ... -
Phenotypic characterization of the goat population of Santa Elena province (Ecuador)
(UCOPress. Cordoba University Press, 2020)It was proposed to typify phenotypically the goats of the Santa Elena province, Ecuador, and to test if there were different phenotypes. 344 animals were sampled in different types of production systems. The following ... -
Phenotypic plasticity of European larch radial growth and wood density along a-1,000 m elevational gradient
(Wiley, 2021-02)Phenotypic plasticity is a key mechanism for sedentary long-living species to adjust to changing environment. Here, we use mature Larix decidua tree-ring variables collected along an elevational transect in the French Alps ... -
Phenotypic variation of basic wood density in Pinus ponderosa plus trees = Variación fenotípica de la densidad básica de la madera de árboles plus de Pinus ponderosa
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)Phenotypic selection generally reduces the variability of both the selected trait and other associated characteristics. Some species show a negative strong relationship between growth traits and wood ... -
Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations
(2018-03)Peripheral sites usually offer suboptimal conditions for species with wide distributions, where expression of phenotypic variability and potential interspecific hybridization might be enhanced. The Patagonian steppe, the ... -
Phylogeography of two hybridizing southern beeches (Nothofagus spp.) with different adaptive abilities
(Springer, 2011-12-17)In phylogenetically related plant species, hybridization can influence their current genetic structure. Long-lasting hybridization may be related to persistence in shared glacial refugia, where the differential abilities ... -
Physiological and molecular mechanisms underlying the integration of light and temperature cues in Arabidopsis thaliana seeds
(Wiley, 2017-09-23)The relief of dormancy and the promotion of seed germination are of extreme importance for a successful seedling establishment. Although alternating temperatures and light are signals promoting the relief of seed dormancy, ... -
