(Sociedad Argentina de Botánica (SAB), 2024-03-08)Introducción y objetivos: El avance de la frontera urbana ha causado la pérdida de ecosistemas naturales. En el sector serrano del valle de Traslasierra (Córdoba, centro de Argentina), la población aumentó en los últimos ... -
Evaluation of degradation of organophosphate insecticide residues in stored corn (Zea mays L.) grains
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2021-06-15)The aims of this work were to monitor the dissipation dynamics of the organophosphate insecticides applied to corn grains stored in supervised experiments, establish the dissipation dynamics and determine the minimum period ... -
Genetic architecture of photosynthesis in Sorghum bicolor under non-stress and cold stress conditions
(Oxford University Press, 2017-10-03)Sorghum (Sorghum bicolor L. Moench) is a C4 species sensitive to the cold spring conditions that occur at northern latitudes, especially when coupled with excessive light, and that greatly affect the photosynthetic rate. ... -
Actividad de cletodim y haloxifop R-metil en el suelo y su efecto fitotóxico en el cultivo de maíz (Zea mays)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2017-12-27)Los herbicidas haloxifop R-metil y cletodim pueden persistir activos en el suelo causando efectos fitotóxicos a cultivos de gramíneas cuando son aplicados próximos a la siembra. En este trabajo se realizaron experimentos ... -
The resurgence of the South American locust (Schistocerca cancellata)
(The Orthopteristis Society, 2017-09)The South American locust (Schistocerca cancellata Serville, 1838) was the most destructive agricultural pest in late 1800’s to early to mid 1900’s Argentina. However, since the 1950s its numbers decreased considerably ... -
Plant carbohydrate content limits performance and lipid accumulation of an outbreaking herbivore
(The Royal Society, 2020-12-09)Locusts are major intermittent threats to food security and the ecological factors determining where and when these occur remain poorly understood. For many herbivores, obtaining adequate protein from plants is a key ... -
Systems management strategies for increasing alfalfa use in warm‐humid regions
(Wiley, 2024-05-16)Alfalfa use (Medicago sativa L.; “lucerne”) in warm, humid regions of the world represents a potential area of expansion for the alfalfa industry. The objective of this review paper is to demonstrate how alfalfa forage ... -
Genetic characterization of sunflower breeding resources from Argentina: assessing diversity in key open-pollinated and composite populations
(Cambridge University Press, 2013-03-25)Open-pollinated (OPs) and composite populations (CPs) represent a valuable resource for sunflower breeding programmes. However, little is known about the levels and distribution of genetic variation within each of these ... -
Emergencia postinvernal y fluctuación poblacional de adultos del picudo perforador de la caña de azúcar, Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae)
(Estación Experimental Agroindustrial Obispo Colombres (EEAOC), 2021)El objetivo de este trabajo fue caracterizar la dinámica de emergencia postinvernal de Acrotomopus atropunctellus (Boheman) (Coleoptera: Curculionidae) y su fluctuación poblacional en la localidad de Ranchillos, departamento ... -
Climate change expected to improve digestive rate and trigger range expansion in outbreaking locusts
(Wiley, 2022-07-01)Global climate change will probably exacerbate crop losses from insect pests, reducing agricultural production, and threatening food security. To predict where crop losses will occur, scientists have mainly used correlative ... -
Are all edges equal? Microclimatic conditions, geographical orientation and biological implications in a fragmented forest
(Elsevier, 2019-08-01)In fragmented forests the edges experience changes in microclimatic conditions, which are referred to as “abiotic edge effect”, and differ according to geographical orientation and season. These microclimatic changes could ... -
Field bands of marching locust juveniles show carbohydrate, not protein, limitation
(Elsevier, 2023-09-19)Locusts are grasshoppers that migrate en masse and devastate food security, yet little is known about the nutritional needs of marching bands in nature. While it has been hypothesized that protein limitation promotes locust ... -
Análisis de ciclo de vida de la carne bovina de exportación de Argentina
(Latin American Asociation of Animal Production, 2023-02-10)El objetivo de este estudio fue evaluar el ciclo de vida de la carne vacuna producida en un sistema de cría y recría silvopastoril, con engorde en feedlot, en Santiago del Estero, Argentina y faenada en un frigorífico ... -
Band movement and thermoregulation in Schistocerca cancellata
(Elsevier, 2022-01)At high density, juvenile locusts create marching hopper bands. Understanding the roles of temperature and vegetation on the movement of these bands shall allow to better forecast and control them. Following a hopper band ... -
Dissecting the genetic control of natural variation in sorghum photosynthetic response to drought stress
(Oxford Academic Press, 2022-05-23)Drought stress causes crop yield losses worldwide. Sorghum is a C4 species tolerant to moderate drought stress, and its extensive natural variation for photosynthetic traits under water-limiting conditions can be exploited ... -
Use of the CSM-CROPGRO-peanut model in Argentina to estimate optimal sowing date and crop water productivity under different soil water content
(Instituto PROS, 2022-10-11)Almost 99% of Argentine peanut production is localized in Córdoba province, mainly under a rainfed regime. In this region, rainfall fluctuations can lead to droughts of varying severity. The peanut optimum sowing date can ... -
Open Hardware in Science: The Benefits of Open Electronics
