Ecosystem services and disservices associated with pastoral systems from Patagonia, Argentina –A review
Tittonell, Pablo Adrian; Hara, Sofia Maria; Alvarez, Valeria Esther; Aramayo, Maria Valeria Del Luján; Bruzzone, Octavio Augusto; Easdale, Marcos Horacio; Enriquez, Andrea Soledad; Laborda, Luciana; Trinco, Fabio Daniel; Villagra, Edgar Sebastian; El Mujtar, Veronica Andrea (EDP Sciences, 2021-11-11)Pastoral systems worldwide secure rural livelihoods in the harshest environments on Earth. Their low productivity per area unit or head makes them the subject of much criticism with regard to their environmental impact, ... -
Effect of volcanic ash over Orthoptera survival in Patagonia
Fernandez Arhex, Valeria Cristina; Amadio, Maria Emilia; Enriquez, Andrea Soledad; Pietrantuono, Ana Laura; Becker, Guillermo Fernando; Bruzzone, Octavio Augusto (2015-04)The aim of this work was to evaluate the ash toxicity from the Puyehue-Cordón Caulle volcanic complex on the survival of two Orthopteran species: the grasshoper Dichroplus vittigerum and the green locust Brugilis sp. Two ... -
Factors influencing the effectiveness of group interactions among international and interdisciplinary early‑career researchers working toward environmental sustainability in climate change
Enriquez, Andrea Soledad; Temoltzin Loranca, Yunuén; LLanos, Eduardo; Schrapffer, Anthony; Jansen, Sarah; Adade Williams, Portia; Saravia Tomasina, Celmira; Perez, Natalia Jesica; Kuperman, Marcelo Nestor (Springer, 2022-11)Global warming is a current problem that needs to be addressed by collaborating with researchers from different disciplines and expertise. There is a concern about training the next generation of scientists to holistically ... -
Grazing intensity levels influence C reservoirs of wet and mesic meadows along a precipitation gradient in Northern Patagonia
Enriquez, Andrea Soledad; Chimner, Rodney Allen; Cremona, Maria Victoria; Diehl, Paula; Bonvissuto, Griselda (Springer, 2015-06)Wet meadows are important ecosystems for forage production and as carbon reservoirs in semi-arid areas. In Patagonia, Argentina, large areas of wet meadows have been classified as overgrazed by livestock. The objective of ... -
Immobilization and stabilization of volcanic ash in soil aggregates in semiarid meadows of Northern Patagonia
Enriquez, Andrea Soledad; Necpalova, Magdalena; Cremona, Maria Victoria; Peri, Pablo Luis; Six, Johan (Elsevier, 2021-06-15)Although volcanism may be perceived by the society as a phenomenon with mostly negative consequences, this is not always the case especially for natural systems. There is a limited knowledge on how the deposited pristine ... -
Integrating family farmers’ perceptions with meteorological records and national climate change projections to enhance site-specific adaptation knowledge
Enriquez, Andrea Soledad; Fernandez, Manuela Teresa; Aramayo, Maria Valeria Del Lu; De Pascuale Bovi, Juan Alberto; Ocariz, María Paula; Tittonell, Pablo Adrian (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 ... -
Latitude, Elevation, and Mean Annual Temperature Predict Peat Organic Matter Chemistry at a Global Scale
Verbeke, Brittany A.; Lamit, Louis J.; Lilleskov, Erik A.; Hodgkins, Suzanne B.; Basiliko, Nathan; Kane, Evan S.; Andersen, Roxane; Artz, Rebekka R. E.; Benavides, Juan Carlos; Enriquez, Andrea Soledad; Chanton, Jeffrey P. (Wiley, 2022-02)Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A global picture of the variations in peat organic matter chemistry ... -
Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
Enriquez, Andrea Soledad; Chimner, Rodney Allen; Cremona, Maria Victoria (Elsevier, 2014-10)Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ... -
Particulate organic carbon is a sensitive indicator of soil degradation related to overgrazing in Patagonian wet and mesic meadows
Enriquez, Andrea Soledad; Cremona, Maria Victoria (Springer, 2018-06)Patagonian meadows are key for the development and sustainability of rural environments. However, they have been degraded due to a combination of weather conditions and overgrazing. Total soil organic carbon (TOC) has been ... -
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 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 ... -
Variation in carbon and nitrogen concentrations among peatland categories at the global scale
Watmough, Shaun; Gilbert-Parkes, Spencer; Basiliko, Nathan; Lamit, Louis; Lilleskov, Erik; Andersen, Roxanne; del Aguila-Pasquel, Jhon; Artz, Rebekka; Benscoter, Brian; Borken, Werner; Enriquez, Andrea Soledad; Zahn, Geoff (PLOS, 2022-11-23)Peatlands account for 15 to 30% of the world’s soil carbon (C) stock and are important controls over global nitrogen (N) cycles. However, C and N concentrations are known to vary among peatlands contributing to the uncertainty ...
