(Elsevier, 2022-11)In the Argentine Puna, innovation proposals for the production of vicuña fiber represent a strategic opportunity for local communities. However, the development of these proposals, essential for the addition of local value, ... -
Sisal wool skin disease in Merino sheep in the Argentine Patagonia region: Identification and molecular diagnosis of Corynebacterium bovis from skin lesions
(Wiley, 2022-09)Background: Sisal wool condition is a skin disease affecting Merino sheep in the Argentine Patagonia region. Corynebacterium spp. isolates have previously been isolated from skin swabs from lesions, while specific ... -
Wind disrupts trail pheromone communication in the leaf-cutting ant Acromyrmex lobicornis
(Elsevier, 2022-10)Although wind is a ubiquitous component of ecological systems and might affect pheromone communication, its effects have not been studied in depth. To test whether wind impacts trail pheromone behaviour, we studied the ... -
Stand development stages and recruitment patterns influence fine-scale spatial genetic structure in two Patagonian Nothofagus species
(Springer, 2022-05)Key message: Nothofagus alpina (Poepp. et Endl.) Oerst. and Nothofagus obliqua (Mirb.) Oerst forests have strong fine-scale spatial genetic structures. The intensity of genetic structure patterns differed according to ... -
Evaluación de la efectividad del Triclabendazol como fasciolicida en caprinos de la provincia de Neuquén, Argentina.
(Facultad de Ciencias Veterinarias, Universidad Nacional del Litoral, 2021-11-02)Debido al uso frecuente del triclabendazol (TCBZ) por parte de los productores, sumado al reporte reciente de resistencia de Fasciola hepatica al fármaco detectada en rodeos y majadas de Neuquén, se llevó a cabo el presente ... -
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
