Integrating family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
(Springer, 2023-12)Adaptation strategies to climate change (CC) that do not consider local perspectives tend to fail at specifc sites. Searching for complementary actions, we aimed to assess how farmers’ perceptions about climatic hazards ... -
Drylands becoming drier: evidence from North Patagonia, Argentina
(Springer, 2023-12)In the last decades, Northern Patagonia (Argentina) has shown linear trends to drier conditions in distinct hydrological variables. Therefore, North Patagonia climate changes were studied using streamfow data of Neuquén ... -
Optimal automatic enhanced ERA5 daily precipitation data for environmental and agricultural monitoring tools in scarce data regions
(Springer, 2023-11-10)The development of monitoring and early warning tools for environmental and agricultural applications is highly restricted in scarce climate data regions. In particular, precipitation data is a key input for several ... -
Flight capabilities of invasive yellowjacket Vespula germanica drones: the effect of kinship and nutrition
(Wiley, 2024-01)Dispersal is a multifactorial process which may influence, among several others, population dynamics, inbreeding likelihood, and mate competition. For species that disperse by flight, many studies have suggested that ... -
Damage reduction of Acromyrmex lobicornis in Pinus ponderosa using mixed pine species in combination with push–pull tools
(Wiley, 2023-11)Leaf-cutting ants (LCAs) cause significant damage to forest plantations and are mainly managed by broad-spectrum synthetic insecticides. In Patagonia, Pinus ponderosa (Pinales: Pinaceae) (Douglas 1836) and Pinus contorta ... -
Ecosystemic structural–functional approach of the state and transition model
(Wiley, 2011-02)Objective: To contribute to the integration of key ecological concepts such as dynamic equilibrium, critical threshold, resistance and resilience to the ‘State and Transition Model’ (STM), in order to apply them in a more ... -
Resident Hymenopteran Parasitoids with Potential Drosophilid Associations in Andean North Patagonia: Implications for the Biological Control of the Spotted Wing Drosophila
(Springer, 2023-09)The spotted wing drosophila, Drosophila suzukii Matsumura, is native to Southeast Asia and has become a serious pest of soft-skinned fruits worldwide. Several control methods are being tested worldwide as part of an ... -
Clone differences among young Salix humboldtiana Willd. from Patagonia
(Springer, 2023-09)Willows represent some of the most extended tree crop species worldwide. Understanding their global architecture could help improving the forestry based on these species and thus the associated economic activities. Our ... -
Polistes dominula (Hymenoptera: Vespidae) paper wasps detect native grasshoppers using olfactory cues
(Wiley, 2023-10)Polistes dominula is an invasive social wasp that preys on the grasshopper Dichroplus elongatus, which constitutes a potential agricultural pest in Northwest Patagonia. This grasshopper feeds on a wide variety of plants, ... -
Triclabendazole resistance in Fasciola hepatica: First report in sheep from the Santa Cruz province, Argentinian Patagonia
(Elsevier, 2023-10)In the fall of 2022, decreased triclabendazole (TCBZ) efficacy against F. hepatica was suspected in a sheep farm located in the Santa Cruz province, Argentinian Patagonia. Since TCBZ-resistance in F. hepatica has never ... -
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 ... -
Autorraleo: alternativa para determinar la pendiente de la relación lineal tamaño-densidad, mediante su impacto en la estimación del volumen del rodal = Self-thinning: alternative to determine the slope of the relationship size-density, by means of its impact on the estimation of stand volume
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2019)Los índices de densidad de rodal son utilizados para diseñar tablas de producción, diagramas de manejo de la densidad, simuladores de crecimiento y establecer regímenes de raleo, siendo el más difundido el índice de rodal ... -
