Occurrence patterns of the endangered Yellow Cardinal Gubernatrix cristata in north-east Argentina: only in savannahs and at sites away from roads
(BirdLife International, 2023)The endangered Yellow Cardinal Gubernatrix cristata is under pressure from habitat loss and from capturing for the cage bird trade. In north-east Argentina it is known to be associated with the Espinal ecoregion, but no ... -
Bird functional and taxonomic diversity in xerophytic forests: contributing to balance bird conservation and livestock production
(Elsevier, 2023-10)Biodiversity is increasingly dependent on the ecological state of agricultural and livestock systems. Here, we assess the relationship between bird functional and taxonomic diversity and forest structure along a gradient ... -
Identification of Molecular Markers and Candidate Genes Associated with Time to Flowering and Length of Reproductive Period in Soybean Through Association Mapping
(Springer, 2023-06)Adaptation to temporal stress can be achieved by modifying flowering time and lengthening the reproductive period. To identify genotypes, molecular markers, and genes related with these traits, a set of 94 soybeans were ... -
Reducción de emisiones de carbono por deforestación evitada en bosques del Espinal (Entre Ríos, Argentina) = Reduction of emissions by avoided deforestation in forests of Espinal (Entre Ríos, Argentina)
(Universidad Distrital Francisco José de Caldas, Colombia, 2021-12)Se estimó el carbono (C) almacenado en la biomasa aérea de bosques nativos del Espinal (Distrito del Ñandubay, provincia de Entre Ríos, Argentina) y la reducción de emisiones de CO2 por deforestación evitada. Se utilizó ... -
Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina = Modelos alométricos de biomassa aérea para Prosopis affinis Spreng. em florestas nativas Espinal da Argentina
(Departamento de Engenharia Agrícola, Universidade Federal de Campina Grande, 2019-06)Estimation of carbon stored in forest ecosystems requires accurate biomass prediction tools. The objective of this study was to determine the individual aerial biomass of Prosopis affinis and its distribution by component, ... -
Biomass Carbon and Nitrogen allocation in different tree species: do tree compartments and size affect C:N relationship?
(Finnish Society of Forest Science, 2022)Tree carbon (C) and nitrogen (N) concentrations and C:N ratio are critical for understanding the elemental compositions of forests, N use efficiency, productivity and the biogeochemical cycles. We evaluate differences in ... -
Addition of amendments to restore a compacted soil under no-tillage system
(Universidade Estadual de Maringá, 2023-04)The addition of organic and inorganic amendments can improve soil structure and reduce soil compaction. In this context, this study aimed to evaluate whether the application of amendments reduces penetration resistance ... -
Field availability and avoidance of imidacloprid-treated soybean seeds and cotyledons by birds
(Wiley, 2023-02)Treated seeds and their cotyledons can present a toxicological risk to seed-eating birds. To assess whether avoidance behavior limits exposure and consequently the risk to birds, three fields were sown with soybeans. Half ... -
The allometric relationships between biomass and nitrogen of vegetative organs affect crop N status in maize at silking stage
(Elsevier, 2023-04)In maize (Zea mays, L.) changes in the partitioning of biomass (W) and nitrogen (N) between organs linked to photosynthetically active tissues, such as leaves (with high N concentration, %N) and organs related to supporting ... -
DNA damage and oxidative stress in gill cells of Cnesterodon decemmaculatus exposed to pesticides by runoff source in an agricultural basin
(Wiley, 2023-01)In our country, great concern exists about diffuse pollution cause by the great use of pesticides in rural environments. A thorough analysis is needed to generate information, know the real situation and thus, be able to ... -
Spatial distribution of pesticides in surface water of the Estacas stream (Argentine Espinal region) associated with crop production
(Springer, 2023-01)The Espinal region (Entre Ríos, Argentina) has sufered land use changes caused by expansion of the agricultural frontier. This expansion has led to an increased use of pesticides. This study is aimed at better understanding ... -
Relación cartográfica entre variables hidrológicas y de degradación por pérdida de suelo superficial: sitio piloto A° Estacas, Entre Ríos
(Asociación Argentina de la Ciencia del Suelo, 2022-12)El aumento del área agrícola en el norte de la provincia de Entre Ríos resulta de la pérdida del bosque nativo. Este cambio del uso del suelo impacta los servicios ecosistémicos que brindan las cuencas hidrográficas, e ... -
Artificial perches for birds in deforested areas favour a seed rain similar to woodland remnants
(Springer, 2022-11)The lack of seeds represents one of the highest difficulties to overcome for the ecological restoration of areas that have been deforested. This study evaluates the effectiveness of artificial perches in increasing the ... -
Diversified crop sequences to reduce soil nitrogen mining in agroecosystems
(Elsevier, 2022-10)Nitrogen (N) is the primary driver of increased global food supply, but has environmental consequences from both under- and over-fertilisation. While over-fertilisation and reactive nitrogen release onto the environment ... -
Defining soybean maturity group options for contrasting weather scenarios in the American Southern Cone
(Elsevier, 2022-10)Soybean genotypes are grouped in maturity groups (MG) based on the response to photoperiod, and a genotype belonging to a particular MG is recommended according to latitude and planting date. From an agronomic viewpoint, ... -
Oportunidades para la cadena de maíz en Entre Ríos
