ROS-Scavenging Enzymes as an Antioxidant Response to High Concentration of Anthracene in the Liverwort Marchantia polymorpha L.
(MDPI, 2021-07)Marchantia polymorpha L. responds to environmental changes using a myriad set of physiological responses, some unique to the lineage related to the lack of a vascular- and root-system. This study investigates the physiological ... -
Mass fux decay timescales of volcanic particles due to aeolian processes in the Argentinian Patagonia steppe
(Springer Nature, 2020-09)We investigate the timescales of the horizontal mass flux decay of wind remobilised volcanic particles in Argentina, associated with the tephra-fallout deposit produced by the 2011–2012 Cordón Caulle (Chile) eruption. ... -
Inter-community and on-farm asymmetric organic matter allocation patterns drive soil fertility gradients in a rural Andean landscape.
(Wiley, 2020-12)Soil fertility in agricultural landscapes is driven by complex interactions between natural and anthropogenic processes, with organic matter (OM) inputs playing a critical role. Asymmetric allocation patterns of these ... -
A Multi-Objective Model Exploration of Banana-Canopy Management and Nutrient Input Scenarios for Optimal Banana-Legume Intercrop Performance
(MDPI, 2021-02)Bananas on smallholder farmers in the African Great Lakes region are often pruned to illuminate shorter understory intercrops, reducing overall farm profitability. The impact of this practice on environmental and nutritional ... -
The educational community and its knowledge and perceptions of native and invasive alien species
(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 ... -
Redefining the field to mobilize three-dimensional diversity and ecosystem services on the arable farm
(Elsevier, 2021-01)In this article we explore the concept and implications of three-dimensional (spatial, temporal, and genetic) in-field crop diversification to inform systems redesign towards ecological intensification. We first present a ... -
Lo rural y lo científico: La presencia de la Estación Experimental Regional Agropecuaria (EERA) INTA Bariloche 1962-1968
(Universidad Nacional de Quilmes, 2014-07)En este trabajo se discute el modo en que desde una práctica científica se toma lo rural en la estepa norpatagónica durante la segunda mitad del siglo XX, observando la intervención de estudios científicos asociados a la ... -
Back to the people: The role of community-based responses in shaping landscape trajectories in Oaxaca, Mexico.
(Elsevier, 2021-01)Land use change results from top-down drivers, such as policies, trade, and migration. Land use change may also result from community-based responses. In Mexico, rural communities govern most of the country's forests. This ... -
Assessing farmer perceptions on livestock intensification and associated trade-offs using fuzzy cognitive maps; a study in mixed farming systems in the mid-hills of Nepal
(Wiley, 2023-02)Intensified livestock production is considered as a promising pathway for smallholder farmers. Nevertheless, this pathway may entail prohibitive investment requirements of labour, capital or trade-offs at farm level that ... -
Phenotypic characterization of the goat population of Santa Elena province (Ecuador)
(UCOPress. Cordoba University Press, 2020)It was proposed to typify phenotypically the goats of the Santa Elena province, Ecuador, and to test if there were different phenotypes. 344 animals were sampled in different types of production systems. The following ... -
Upstream-Downstream Influence of Water Harvesting Techniques (Jessour) on Soil Water Retention in Southeast Tunisia
(MDPI, 2023-04)Weather parameters and soil moisture profiles were measured at an hourly time step during four agricultural years (September to October, from 2018–19 to 2021–22) in two Jessour (water harvesting cultivated terraces) of the ... -
Mulinum spinosum y la carne de cordero: detección de su presencia en ovinos vivos = Mulinum spinosum and lamb meat: detecting its presence on live sheep
(UCOPress. Cordoba University Press, 2011)En Patagonia, la ganadería ovina es una de las principales actividades económicas, pero la calidad de la carne de cordero se ve afectada por el sabor desagradable que toma a causa de la ingesta de neneo (Mulinum spinosum ... -
Variation in carbon and nitrogen concentrations among peatland categories at the global scale
(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 ... -
Control de la dinámica folicular ovárica en Llamas (Lama Glama) en posparto temprano
(UCOPress. Cordoba University Press, 2011)Se evaluó el efecto del acetato de medro-xiprogesterona (AMP, esponja intravaginal) con o sin inyección de benzoato de estradiol (BE) sobre el patrón de regresión folicular, la emergencia de la onda folicular y la tasa ... -
Climate warming differently affects Larix decidua ring formation at each end of a French Alps elevational gradient.
(Springer, 2020)Key message: The ongoing global warming tends to reduce Larix decidua radial growth and ring wood density at the bottom of an elevational gradient in the French Alps, while it has a less marked effect at the top. Context: ... -
Impact of agroecological management on plant diversity and soil-based ecosystem services in pasture and coffee systems in the Atlantic forest of Brazil
(Elsevier, 2021)The development of agroecosystems that can provide multiple ecosystem services with a reduced need of external inputs, requires management practices that foster ecological processes to enhance soil quality and crop ... -
Implications of landscape configuration on understory forage productivity: a remote sensing assessment of native forests openings
(Springer, 2021-08)Sound management of native forests used for cattle grazing requires understanding the dynamics of forage productivity in the openings. Despite their importance, forage productivity drivers in highly heterogeneous forested ... -
Deciphering the transcriptomic regulation of heat stress responses in Nothofagus pumilio
(Public Library of Science (PLOS), 2021-03)Global warming is predicted to exert negative impacts on plant growth due to the damaging effect of high temperatures on plant physiology. Revealing the genetic architecture underly ing the heat stress response is therefore ... -
Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefit
(Elsevier, 2020)Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised, government-controlled breeding schemes which have been implemented in many developing countries. An innovative ... -
