Particulate organic carbon is a sensitive indicator of soil degradation related to overgrazing in Patagonian wet and mesic meadows
(Springer, 2018-06)Patagonian meadows are key for the development and sustainability of rural environments. However, they have been degraded due to a combination of weather conditions and overgrazing. Total soil organic carbon (TOC) has been ... -
Patagonian ñire (Nothofagus antarctica) combined with green tea - Novel beverage enriched in bioactive phytochemicals as health promoters
(Wiley, 2022-09)Background: Polyphenol-enriched tea is an interesting product for food industries under the current consumer demands. This study aimed at evaluating the Nothofagus antarctica (NA) species as a valuable source of bioactive ... -
Patch choice from a distance and use of habitat information during foraging by the parasitoid Ibalia leucospoides
(2012-06)1. In environments in which resources are distributed heterogeneously, patch choice and the length of time spent on a patch by foragers are subject to strong selective pressures. This is particularly true for parasitoids ... -
Patch exploitation behaviour by a parasitoid of a forest pest: The influence of host cues and intra- and interspecific interactions
(Wiley, 2024-03)For parasitoids, host foraging is the most significant activity for their reproductive success, as it directly translates into offspring production. Therefore, foraging behaviour and patch-use decisions by parasitoids still ... -
Pattern of natural introgression in a Nothofagus hybrid zone from South American temperate forests
(Springer-Verlag Berlin Heidelberg, 2017-03-29)Interspecific gene flow is a common phenomenon in Nothofagaceae species; however, the dynamics of introgression in hybrid zones remains largely unknown. We focused on two ecologically and morphologically different Nothofagus ... -
Perfiles de diámetro de fibra en lanas preparto de ovejas merino. 1. Estudio comparativo de líneas genéticas
(Asociación Argentina de Producción Animal, 2010-04)Con el objetivo de evaluar la variabilidad de respuesta en diámetro de fibra de distintos tipos de Merino en el noroeste de la Patagonia argentina, se analizaron características del perfil de diámetros de fibra en 498 ... -
Perfiles de diámetro de fibra en lanas preparto de ovejas merino. 2. Estudio comparativo de estados fisiológicos
(Asociación Argentina de Producción Animal, 2011-02)Se estudió el perfil del diámetro de fibras de lana de ovejas Merino superfinas (n=438) en cuatro estados fisiológicos, según estén preñadas o secas (PRE, SEC, respectivamente) y hayan destetado o no un cordero en el ... -
Perfiles de diámetro de fibra en lanas preparto de ovejas Merino. 3. Utilización de regresiones P-spline para estudiar el efecto del estado fisiológico
(Asociación Argentina de Producción Animal, 2012)Se estudió el perfil del diámetro de fibras (PDF) de lana de ovejas Merino superfinas (n = 200) en pastoreo en el noroeste de la Patagonia argentina. Las ovejas fueron clasificadas en dos edades (E; Adultas y Viejas) y en ... -
Performance of Angora goats, mohair production, and farmer income in extensive livestock systems of north Patagonia, Argentina
(Frontiers Media, 2023-07)Introduction: In Argentina, mohair production is limited exclusively to the Patagonia region. This activity takes place under different biophysical conditions and with marked seasonality in the climatic conditions and ... -
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 ... -
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, ... -
