Exclusión al ganado en bosques mixtos de Patagonia norte bajo uso silvopastoril: Respuestas estructurales y funcionales de la vegetación
(Asociación Argentina de Ecología, 2024-08)Las clausuras en bosques templados se han usado con frecuencia para evaluar los efectos del ganado con objetivos de conservación y restauración. Sin embargo, su empleo con objetivos de manejo en sistemas productivos ... -
Tracking states and transitions in semiarid rangelands: A spatiotemporal archetypal analysis of productivity dynamics using wavelets
(Elsevier, 2024-07)Climate change poses challenges in classifying ecosystem dynamics, as they are influenced by shifting dynamics resulting from changes in climate forces and meteorological variables, including temperature and water availability. ... -
The relevance of integrating multiple sensory modalities into capturing devices: the case of the global pest Sirex noctilio
(Wiley, 2024-07)Sirex noctilio is an invasive forest wasp that affects pines in many parts of the globe and can result in severe economic losses. Current trapping methods for monitoring the pest rely heavily on non-specific semiochemicals. ... -
Allee effects in an invasive social wasp: an experimental study in colonies of Vespula germanica
(Springer Nature, 2023-09)Allee effects rely on the existence of mutually beneficial intraspecific interactions that increase individual fitness and per capita growth rate, as the number of individuals in a population or group increases. When the ... -
Archetypes of climate change adaptation among large-scale arable farmers in southern Romania
(Springer, 2024-07)Effects of climate change and especially the associated climate variability require farmers to adjust to increasing frequencies of extreme events. In the agriculturally highly productive Romanian Plain, the frequency, ... -
Use of near-infrared spectroscopy to estimate physical, anatomical and hydraulic properties of Eucalyptus wood
(Oxford University Press, 2023-03)Tree breeding programs and wood industries require simple, time- and cost-effective techniques to process large volumes of samples. In recent decades, near-infrared spectroscopy (NIRS) has been acknowledged as one of the ... -
Intraspecific phylogeny of a Patagonian fescue: differentiation at molecular markers and morphological traits suggests hybridization at peripheral populations
(Oxford University Press, 2023-05)Background and Aims: Grasses of the Festuca genus have complex phylogenetic relations due to morphological similarities among species and interspecific hybridization processes. Within Patagonian fescues, information ... -
Advancing social insect research through the development of an automated yellowjacket nest activity monitoring station using deep learning
(Wiley, 2024-07)We describe the development and validation of an autonomous monitoring station that identifies and records the movement of social insects into and out of the colony. The hardware consists of an illuminated channel and a ... -
Diurnal High Temperatures Affect the Physiological Performance and Fruit Quality of Highbush Blueberry (Vaccinium corymbosum L.) cv. Legacy
(MDPI, 2024-07)In this study, the physiological performance and fruit quality responses of the highbush blueberry (Vaccinium corymbosum) cultivar Legacy to high temperatures (HTs) were evaluated in a field experiment. Three-year-old V. ... -
Primer mapeo de huertas urbanas en Bariloche: Herramienta de investigación y gestión = First Mapping of Vegetable Gardens in Bariloche: A Research and Management Tool = Primeiro mapeamento de hortas urbanas em Bariloche: Ferramenta de investigação e gestão
(Instituto de Estudios Avanzados, Universidad de Santiago de Chile, 2024-05)La ciudad de Bariloche es paradigmática por su escasa planificación territorial y las marcadas desigualdades socioeconómicas y ambientales en su ejido. Asimismo, desde 1960 la preponderancia la actividad turística ha ... -
Water temperature and microenvironmental factors predict the presence and detection of the snail host of Fasciola hepatica in Andean Patagonia
(Elsevier, 2024-07)The transmission of Fasciola hepatica occurs only where there are -or recently were- aquatic or amphibious snails of the Lymnaeidae family, the intermediate host of this parasite. Direct detection of these snails is ... -
Transcriptomic responses to drought stress in the Patagonian southern beech Nothofagus alpina
(Springer Open, 2024-05)Background: Deciphering the genetic architecture of drought tolerance could allow the candidate genes identification responding to water stress. In the Andean Patagonian forest, the genus Nothofagus represents an ecologically ... -
Higher establishment of nonnative trees with increased harvest intensity in strip cuttings
(Springer, 2024-04-23)Proper management of woody ecosystems is fundamental for human livelihoods and biodiversity conservation. Strip cutting or selective harvesting are proposed as sustainable alternatives to clear-cut logging. However, their ... -
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 ... -
Climate-influenced performance and offspring development of merino sheep in a dry temperate-cold valley
(Elsevier, 2024-04)This study aims to explore the effects of climate on the performance and offspring development of aged Merino sheep relocated from an arid, cold environment with harsh grazing conditions to a dry, temperate-cold valley ... -
Effect of egg production dynamics on the functional response of two parasitoids
(Plos ONE, 2024-03)Functional response describes the number of hosts attacked by a parasitoid in relation to host densities and plays an important role by connecting behavioral-level processes with community-level processes. Most functional ... -
Long-term monitoring reveals the effect of precipitation and silviculture on Nothofagus regeneration in Northern Patagonia mixed forests
(Springer, 2024-04)Background: Tree regeneration is a key component of resilience because it promotes post-disturbance recovery of forests. Northwestern Patagonia from Argentina is occupied by Nothofagus alpina (Na), N. obliqua (No), and N. ... -
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 ... -
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. ... -
Unintended consequences of planting native and non-native trees in treeless ecosystems to mitigate climate change
(Wiley, 2024-03)Naturally treeless ecosystems are being replaced by native and non-native trees worldwide, often through deliberate afforestation using forestry tree species. By introducing species having novel traits, such as relatively ...
