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 ... -
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, ... -
Factors driving historic intercontinental invasions of European pine bark beetles
(Springer, 2022-06)Largely assisted by global trade, alien insect species are being introduced into new territories at unprecedented rates. Among forest insects, pine bark beetles (Coleoptera: Curculionidae, Scolytinae) are a large and diverse ... -
Indole-diterpenes alkaloid profiles of native grasses involved in tremorgenic syndromes in the Argentine Patagonia
(Elsevier, 2022-10-15)One of the main intoxications to livestock in the Patagonia region of Argentina is the tremorgenic disease “Mal de Huecú", attributed to the consumption of the native grasses Poa huecu and/or Festuca argentina. In this ... -
Differential response of natural regeneration to silvopastoral use intensity in mixed forests of northern Patagonia, Argentina
(Elsevier, 2022-07-07)Silvopastoral use (combined livestock and forestry) is widely distributed in South America’s native forests. Without medium to long-term planning, this activity may affect the population dynamics of the dominant canopy ... -
Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)
(Springer, 2022-07-03)In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species can have a strong ... -
Growth curve of early-weaned Hereford calves in a semidesert temperate zone (Patagonia, Argentina)
(Elsevier, 2022-05)In semi desert environments, prone to droughts, beef cow performance can be improved by early weaning. This study aimed to evaluate the growth curve of early weaned calves in a semidesert temperate area such as Patagonia, ... -
Red Argentina de Parcelas Permanentes de Bosques Nativos para promover colaboraciones científicas en estudios de largo plazo
(Asociación Argentina de Ecología, 2022-08)Las parcelas forestales permanentes son áreas de muestreo donde se registran periódicamente la identidad, abundancia y tamaño de los árboles, para estudiar cómo cambian los bosques en relación con el clima, los disturbios ... -
Are winter rangelands enough to satisfy the nutritional requirements of late‑gestation transhumant goats in Patagonia?
(Springer, 2022-08-03)Transhumant herds graze across two different rangeland types according to the season. Winter rangelands differ from summer rangelands in the amount and quality of available fodder, with the former being the less productive. ... -
Population ecology and classical biological control of forest insect pests in a changing world
(Elsevier, 2022-09-15)Forests are important for climate regulation and provide wood and fiber to an increasing human population. Forest systems encompass a large part of the world’s land surface area and they are increasingly threatened by ... -
Nutrient source, management system and the age of the plantation affect soil biodiversity and chemical properties in raspberry production
(Elsevier, 2022-07)Soil biodiversity is the driving force behind most soil processes. While potentially improving plant productivity and food quality, it can be negatively affected by land use and soil management. Raspberry production is ... -
Cryptochromes are the dominant photoreceptors mediating heliotropic responses of Arabidopsis inflorescences
(Wiley, 2021-10)Inflorescence movements in response to natural gradients of sunlight are frequently observed in the plant kingdom and are suggested to contribute to reproductive success. Although the physiological and molecular bases of ... -
Forage ofering and seasonal intake comparisons to evaluate European rabbit threat in Nothofagus forests of southern Patagonia
(Springer Nature, 2022-07-05)Background: The European rabbit (Oryctolagus cuniculus L. 1758) was introduced into diferent regions of the world, generating signifcant trade-ofs that critically impacted native vegetation. Here, we evaluate the rabbit’s ... -
Arid and semiarid rangeland responses to non-stationary temporal dynamics of environmental drivers
(Elsevier, 2022-08)Temporal ecology is a growing research field aimed at understanding how temporal dynamics structure ecological systems in a changing environment. Ecosystems are exposed to accelerating environmental changes —mainly driven ... -
Different drought‑adaptive capacity of a native Patagonian tree species (Nothofagus pumilio) resulting from local adaptation
(Springer, 2021-06)The resistance of different genotypes to abiotic stress may be due to genetic effects and/or to phenotypic plasticity allowing them to acclimate to variable conditions. The contribution of one or the other mechanism ... -
Características de las precipitaciones en zonas áridas de la Patagonia norte, Argentina
(Centro Universitario Rosario de Investigaciones Hidroambientales, Universidad Nacional de Rosario, 2022)La precipitación es determinante de múltiples procesos en zonas áridas. Abordar su variabilidad es difícil en áreas extensas y de baja densidad de registros como la Patagonia norte. El objetivo de este trabajo es caracterizar ... -
