Community-based livestock breeding programmes : essentials and examples
(2015-04)Breeding programmes described as community-based (CBBP) typically relate to low-input systems with farmers having a common interest to improve and share their genetic resources. CBBPs are more frequent with keepers of small ... -
Genetic versus environmental contributions to variation in seedling resprouting in Nothofagus obliqua
(Springer, 2015-04)Resprouting is an almost universal functional trait in temperate angiosperms and confers persistence at an individual level after the loss of above-ground biomass. The importance of genetic versus environmental sources of ... -

(Escuela para Graduados Ing. Agr. Alberto Soriano, Facultad de Agronomía, Universidad de Buenos Aires, 2015-04-22)Desafíos complejos como el desarrollo rural sustentable requieren de la integración de las ciencias sociales y ecológicas, y de un papel activo de las ciencias agropecuarias como interfaz conceptual y metodológica. El ... -
Functional and histopathological changes induced by intraparenchymal injection of kainic acid in the rat cervical spinal cord
(Elsevier, 2015-05)Kainic acid (KA) is an analog of the neurotransmitter glutamate and is widely used as an excitotoxic agent to lesion spinal cord networks, thus, providing an interesting model to learn basic mechanisms of spinal cord injury. ... -
Structural–functional approach to identify post-disturbance recovery indicators in forests from northwestern Patagonia: a tool to prevent state transitions
(Elsevier, 2015-05)The disruption of the natural post-disturbance recovery process, either by changes in disturbance regime or by another disturbance, can trigger transitions to alternative degraded states. In a scenario of high disturbance ... -
Substrates Preference for Pupation on Sawfly Notofenusa surosa (Hymenoptera: Tenthredinidae)
(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 ... -
Un marco ecológico para establecer márgenes de manejo de sistemas silvopastoriles. 1- El caso de ñirantales del norte de la Patagonia, Argentina
(Ediciones INTA, 2015-05-07)En bosques nativos bajo uso silvopastoril, el manejo tiene un fuerte impacto sobre la dinámica y estructura. Por ello, es necesario conocer sus efectos para diseñar prácticas de manejo que mantengan, en el largo plazo, al ... -
Spatial pattern of attacks of the invasive woodwasp Sirex noctilio, at landscape and Stand Scale
(2015-05-18)Invasive insect pests are responsible for important damage to native and plantation forests, when population outbreaks occur. Understanding the spatial pattern of attacks by forest pest populations is essential to improve ... -
El ejercicio de la soberanía alimentaria en las familias campesinas del Valle Calchaquí – el caso de Angastaco, Salta
(Edición del Autor, 2015-05-27)La soberanía alimentaria es un concepto acuñado y construido por las organizaciones sociales. La Vía Campesina lo definió en 1996 como: “el derecho de cada nación de mantener y desarrollar su propia capacidad de producir ... -
Ecophysiological basis of wood formation in ponderosa pine : linking water flux patterns with wood microdensity variables
(2015-06)Climate and stands management have an effect on the process of wood formation via resource availability. To improve knowledge of wood quantity and physical structure, increment cores of ponderosa pine were taken in high- ... -
Cotton as an entry point for soil fertility maintenance and food crop productivity in savannah agroecosystems-Evidence from a long-term experiment in southern Mali
(2015-06)Given the scarcity of manure and the limited land available for fallowing, cotton cultivation with its input credit schemes is often the main entry point for nutrients in cropping systems of West Africa. In an experiment ... -
Identification and molecular characterization of Orf virus in Argentina
(Springer, 2015-06)Orf virus (ORFV) is the etiological agent of contagious ecthyma (CE), a pustular dermatitis of sheep and goats. Outbreaks of ORFV have been observed in all geographical regions of the world, including Argentina. The origin ... -
Grazing intensity levels influence C reservoirs of wet and mesic meadows along a precipitation gradient in Northern Patagonia
(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 ... -
