Life history traits of Sirex noctilio F. (Hymenoptera: Siricidae) can explain outbreaks independently of environmental factors
(2013-12)La avispa Sirex noctilio es una plaga importante de las plantaciones de pino en todo el mundo. Económicamente daño significativo se limita sin embargo a brote poblaciones. Para entender lo que determina la dinámica de los ... -
Life history traits of the coccinellids Scymnus subvillosus and S. interruptus on their prey Aphis spiraecola and A. gossypii: Implications for biological control of aphids in clementine citrus
(Elsevier, 2019-05)Predator-prey interactions are not static, but spatially and temporally dynamic. In addition to the climatic conditions and the prey density, the dynamics of predator populations may be influenced by the suitability of ... -
Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier, 2016-04)Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ... -
Light Quality Environment and Photomorphological Responses of Young Olive Trees
(MDPI, 2021-10)Tree densities have increased greatly in olive orchards over the last few decades. In many annual crop species, increased density reduces the horizontal red/far-red (R/FR) and blue/green (B/G) ratios during canopy development ... -
Limitantes nutricionales y variabilidad espacio-temporal del rendimiento en colza
(2018-04)La información agronómica desarrollada para el cultivo de colza es aún escasa en Argentina. Analizar el efecto de las limitantes nutricionales y de propiedades físicas sobre la variación espacial del rendimiento de colza ... -
Limitantes para el desarrollo de la citricultura en Corrientes
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2012)La Provincia de Corrientes es parte de la región mesopotámica de Argentina, situada en el nordeste (NEA). En el período 1970-1980 la citricultura correntina era una de las más importantes del país y superaba en superficie ... -
Limitantes para la mecanización de cosecha en caña de azúcar del estrato de pequeños productores de Tucumán
(Facultades de Ciencias Veterinarias y Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2021-11)En el sector sucroalcoholero de Tucumán existen 3500 productores con menos de 50 hectáreas. Aproximadamente el 80% de ellos adopta el sistema de cosecha semimecanizada, el cual utiliza la quema para limpieza a pesar que ... -

(Facultad de Ingeniería y Ciencias Hídricas, Universidad Nacional del Litoral, 2019-11)Las pequeñas localidades del noroeste de la Provincia de Santa Fe son conocedoras de los problemas de escasez de agua en cantidad, calidad y oportunidad. Un régimen de precipitaciones irregular, distancias largas a cursos ... -
Linkage disequilibrium patterns, population structure and diversity analysis in a worldwide durum wheat collection including Argentinian genotypes
(BMC, 2021-04-05)Background: Durum wheat (Triticum turgidum L. ssp. durum Desf. Husn) is the main staple crop used to make pasta products worldwide. Under the current climate change scenarios, genetic variability within a crop plays a ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Linking competition with Growth Dominance and production ecology
(2018-04-15)The development of forests over time is influenced by competition for resources among trees, leading to patterns of size hierarchy. These two aspects – competition and size hierarchy – can be examined in conjunction with ... -
Linking diet quality and energy demand in free‐living guanacos: an eco‐physiological innovative approach
(Wiley, 2019-04-18)In adaptive terms, animals are subject to challenges imposed by their environment. To address physiological patterns in wild mammals, the non‐invasive study of glucocorticoid hormones has become the main approach through ... -
Linking ecosystem resistance, resilience, and stability in steppes of North Patagonia
(Elsevier, 2013-01)The main objective of an ecosystem sustainable management is to preserve its capacity to respond and adapt to current disturbances and/or future changes, and maintain the provision of environmental goods and services. Two ... -
Linking farmers' management decision, demographic characteristics and perceptions of ecosystem services in the Southern Pampa of Argentina
(Elsevier, 2020-03-15)In the Pampean region of Argentina, uncultivated areas with spontaneous vegetation, such as the sierras (low hills), are important sites for nature conservation. In the last decades, the “agriculturization” process has ... -
Linking potential biodiversity and three ecosystem services in silvopastoral managed forest landscapes of Tierra del Fuego, Argentina
(Taylor & Francis, 2017-04)Several studies confirm that biodiversity loss endangers ecosystem services (ES) supply and human well-being. A better understanding of biodiversity–ES relationships and effects of biodiversity loss on ES supply is needed. ... -
