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, ... -

Vegetation structure and livestock grazing intensity affect ground-foraging birds in xerophytic forests of Central-East Argentina
(Elsevier, 2022-10)Ground birds are strongly associated with the vegetation structure in natural environments under livestock grazing. Birds that fed on the ground may be the most affected by overgrazing, while those that fed on the shrub ... -
Modelos alométricos de biomasa aérea para Vachellia caven Mol. Molina en bosques nativos del Espinal (Argentina) = Biomass allometric models for Vachellia caven Mol. Molina in native Espinal forests (Argentina)
(Facultad de Ciencias Forestales, Universidad Nacional de Santiago del Estero, 2020-06)La captura y fijación de CO2 atmosférico es uno de los servicios ambientales que proveen los bosques nativos. La biomasa arbórea constituye un indicador de las existencias de carbono y puede ser estimada mediante modelos ... -
Inventario y áreas complementarias para la conservación de las aves de la provincia de Entre Ríos, Argentina
(Universidad Nacional Autónoma de México (UNAM), 2021)La región neotropical se caracteriza por su gran riqueza de aves, cuya protección e inventarios presentan sesgos de representación geográfica y composición de especies. En la provincia de Entre Ríos, las áreas protegidas ... -
Nutrient dynamics in the Paraná River Delta: relationship to the hydrologic regime and the floodplain wetlands
(Elsevier, 2022-04)South America contains the most extensive freshwater wetlands in the world, associated with the floodplains of the Amazon, Orinoco and Paraná rivers. The Paraná River delta is a large wetland system strongly influenced by ... -
Avoidance of neonicotinoid-treated seeds and cotyledons by captive eared doves (Zenaida auriculata, Columbidae)
(Elsevier, 2022-07)Farmland birds can be exposed to neonicotinoids through the ingestion of treated unburied seeds and cotyledons. The aim of this study was to evaluate the avoidance of sorghum with imidacloprid, clothianidin or thiamethoxam, ... -
Quality of the surface water of a basin affected by the expansion of the agricultural frontier over the native forest in the Argentine Espinal region
(Springer, 2022-03)Land use changes have led to the degradation of multiple ecosystem services and affected the quality of aquatic ecosystems. The aims of this study were (i) to assess the expansion of the agricultural border over the native ... -
