Spatial dynamics of a Sirex noctilio woodwasp population within a pine plantation in Patagonia, Argentina
Corley, Juan Carlos; Villacide, Jose Maria; Bruzzone, Octavio Augusto (Wiley, 2007-12)The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) is probably the most important pest of pine tree plantations of the southern hemisphere. We studied the spatial arrangement of an endemic population of the woodwasp ... -
Structure and composition of a thrips community in the Chihuahua Desert, New Mexico, U.S.
Logarzo, Guillermo Alejandro; Zamar, María Inés; Richman, David; Bruzzone, Octavio Augusto (Florida Entomological Society, 2012-03)We examined plant used versus plant availability by a thysanopteran community on 13 woody and perennial native plants in the Chihuahua Desert. Individual plants were sampled with sticky-traps on 8 dates from May 1997 to ... -
Substrates Preference for Pupation on Sawfly Notofenusa surosa (Hymenoptera: Tenthredinidae)
Pietrantuono, Ana Laura; Enriquez, Andrea Soledad; Fernandez Arhex, Valeria Cristina; Bruzzone, Octavio Augusto (Springer, 2015-05)The choices made by insects at different stages of their life cycle are critical for the individual and progeny success. In the case of leaf-miners, during larval development they are not able to make choices until the ... -
The educational community and its knowledge and perceptions of native and invasive alien species
Sosa, Alejandro Joaquin; Jiménez, Nadia L.; Faltlhauser, Ana Claudia; Righetti, Tomás; Mc Kay, Fernando; Bruzzone, Octavio Augusto; Stiers, Iris; Fernández Souto, Adriana (Springer Nature, 2021-11)Environmental education seeks to foster an appreciation for nature and the impact of humans on it while introducing citizens to scientific thinking. Biological invasions affect different aspects of life on earth and mandate ... -
The effects of volcanic ash from Puyehue-Caulle range eruption on the survival of Dichroplus vittigerum (Orthoptera: Acrididae)
Fernandez Arhex, Valeria Cristina; Buteler, Micaela; Amadio, Maria Emilia; Enriquez, Andrea Soledad; Pietrantuono, Ana Laura; Stadler, Teodoro; Becker, Guillermo Fernando; Bruzzone, Octavio Augusto (2013-03)The aim of this work was to evaluate the toxicity of volcanic ash from the volcanic complex Puyehue-Caulle Range on the grasshopper, Dichroplus vittigerum, and compare the results with the effect of diatomaceous earth, an ... -
Tracking floristic archetypes of Patagonian steppes
Easdale, Marcos Horacio; Martin Albarracin, Valeria Leticia; Perri, Daiana Vanesa; Lopez, Dardo Ruben; Bruzzone, Octavio Augusto (Wiley, 2024-03)Questions: The classification of plant communities is a well-established practice in ecology. However, the factors that determine the distribution of common species and the extent of their dominance and overlap are still ... -
Trend-cycles of vegetation dynamics as a tool for land degradation assessment and monitoring
Easdale, Marcos Horacio; Farina, Clara Maria; Hara, Sofía; Perez Leon, Natalia Jesica; Umaña, Fernando; Tittonell, Pablo Adrian; Bruzzone, Octavio Augusto (Elsevier, 2019-07)The use of time series of Normalized Difference Vegetation Index (NDVI), obtained from satellite sensors has become frequent in studies for land degradation assessment and monitoring. Linear trends of NDVI are usually ... -
Vegetation responses to variations in climate: A combined ordinary differential equation and sequential Monte Carlo estimation approach
Bruzzone, Octavio Augusto; Perri, Daiana Vanesa; Easdale, Marcos Horacio (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 ... -
Water-mediated changes in plant–plant and biological soil crust–plant interactions in a temperate forest ecosystem
Pissolito, Clara; Garibotti, Irene Adriana; Varela, Santiago Agustin; Arana, María Veronica; Gonzalez Polo, Marina; Marchelli, Paula; Bruzzone, Octavio Augusto (Copernicus Publications, 2019-04-09)In the quest to understand how biotic interactions respond to climate change, one area that remains poorly explored is how interactions involving organisms other than vascular plants will respond. However the interactions ...
