Varroa destructor and viruses association in honey bee colonies under different climatic conditions
(2016-06)Honey bee colonies are threatened by multiple factors including complex interactions between environmental and diseases such as parasitic mites and viruses. We compared the presence of honeybee-pathogenic viruses and Varroa ... -
Vectorial competence of Amblyomma tonelliae to transmit Rickettsia rickettsii
(2016-12)The aim of this work was to test the vectorial competence of Amblyomma tonelliae (Ixodida: Ixodidae) to transmit Rickettsia rickettsii (Rickettsiales: Rickettsiaceae), the agent of Rocky Mountain spotted fever (RMSF). All ... -
Vegetación espontánea como reservorio de sírfidos en agroecosistemas de frutilla, Tucumán, Argentina
(Sociedad Argentina de Agroecología, 2021)El cultivo de frutilla es afectado principalmente por arañuelas, trips y pulgones (Dughetti et al., 2017; Cingolani & Greco, 2018), siendo su control principalmente dependiente de agroquímicos. -
Vegetation composition and structure changes following roller-chopping deforestation in central Argentina woodlands
(2016-10)Driven by the pressure of increasing forage production, dry forests and woodlands of Argentina are suffering one of the highest deforestation rates in the world. In this study we combined field work and a remote sensing ... -
Vegetation Productivity in Natural vs. Cultivated Systems along Water Availability Gradients in the Dry Subtropics
(2016-12)The dry subtropics are subject to a rapid expansion of crops and pastures over vast areas of natural woodlands and savannas. In this paper, we explored the effect of this transformation on vegetation productivity (magnitude, ... -
Vegetation responses to variations in climate: A combined ordinary differential equation and sequential Monte Carlo estimation approach
(Elsevier, 2023-03)Vegetation responses to variation in climate are a current research priority in the context of accelerated shifts generated by climate change. However, the interactions between environmental and biological factors still ... -
Vegetation structure and livestock grazing intensity affect ground-foraging birds in xerophytic forests of Central-East Argentina
(Elsevier, 2022-10)Ground birds are strongly associated with the vegetation structure in natural environments under livestock grazing. Birds that fed on the ground may be the most affected by overgrazing, while those that fed on the shrub ... -
Vegetation structure is as important as climate for explaining ecosystem function across Patagonian rangelands
(2014-11)1. Drylands cover about 41% of Earth’s land surface, and 65% of their area supports domestic livestock that depends on the above-ground net primary productivity (ANPP) of natural vegetation. Thus, understanding how biotic ... -
Vegetation type mapping in Southern Patagonia and its relationship with ecosystem services, soil carbon stock, and biodiversity
(MDPI, 2024-02-29)Vegetation Type (VT) mapping using Optical Earth observation data is essential for the management and conservation of natural resources, as well as for the evaluation of the supply of provisioning ecosystem services (ESs), ... -
Vegetation types of the Arid Chaco in Central-Western Argentina
(International Association for Vegetation Science, 2023-07-24)Objetivos: Abordamos las siguientes preguntas: 1) ¿Cuáles son los principales tipos de vegetación que se dan actualmente en el Chaco Árido? 2) ¿Difieren esos tipos de vegetación en términos de composición florística, ... -
Vegetative and reproductive plasticity of broccoli at three levels of incident photosynthetically active radiation
(2007)To study the effects of shading on the growth, development, dry matter partitioning, and plant architecture of broccoli, "Legacy" hybrid plants were grown in pots in a greenhouse under black shading meshes to generate ... -
Vegetative and reproductive responses, oil yield and composition from olive trees (Olea europaea) under contrasting water availability during the dry winter‐spring period in central Argentina
(Wiley, 2014-01)In Argentina, the climatic pattern of the olive production areas is characterised by a marked water deficit during winter and spring months. A field experiment was carried out to evaluate the effect of water availability ... -
Vegetative growth, yield, and crop water productivity response to different irrigation regimes in high density walnut orchards (Juglans regia L.) in a semi-arid environment in Argentina
(Elsevier, 2022-12)The area dedicated to walnut orchards has recently expanded in central-western Argentina. Nevertheless, studies on crop water demand are scarce and fundamental in semi-arid environments. This work aims to evaluate the ... -
Vegetative propagation and proposal for sustainable management of Valeriana carnosa Sm., a traditional medicinal plant from Patagonia
(Elsevier, 2019-09)Valeriana carnosa is an important medicinal herb in the Patagonian popular medicine. The underground parts of this native species are used for the preparation of various formulations in the traditional health system for ... -
Vegetative propagation of four Argentinian provenances of Neltuma spp
(Universidade Estadual do Norte Fluminense., 2024)Neltuma chilensis and N. flexuosa (mesquite, ex Prosopis) are well-adapted and multi-purpose native species trees of arid and semiarid regions of Argentina that produce high quality timber wood, charcoal, firewood, fruit ... -
Vegetative propagation of patagonian cypress, a vulnerable species from the subantarctic forest of South America
(Universidad Austral de Chile, 2009)Increasing risks of loosing forest genetic resources and the need for a sustainable quality wood supply make focusing research efforts on undomesticated tree species necessary. The study of their genetic variation in ... -
Vegetative structure and distribution of oil yield components and fruit characteristics within olive hedgerows (cv. Arbosana) mechanically pruned annually on alternating sides in San Juan, Argentina
(2018)In olive hedgerows mechanical pruning is needed to control hedgerow dimensions for canopy illumination and access by harvesting machinery but yield responses to pruning strategies remain unclear. This study records the ... -
