Accumulation of current-use pesticides, cholinesterase inhibition and reduced body condition in juvenile one-sided livebearer fish (Jenynsia multidentata) from the agricultural Pampa region of Argentina
(2017-10)The aim of this study was to characterize the level and nature of the pesticide contamination received by one-sided livebearer fish (Jenynsia multidentata) from a watercourse situated within the main agricultural region ... -
Anuran responses to spatial patterns of agricultural landscapes in Argentina
(2016-12)Context: Amphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives: ... -
Behavioral and physiological changes in the passerine Agelaioides badius following the ingestion of coated seeds with imidacloprid in a 30-day experiment
(Elsevier, 2023-12)The wide use of neonicotinoid seed treatment represents a hazard for farmland birds that feed on treated seeds. This study aimed to characterize the long-term effects of the neonicotinoid imidacloprid (IMI) in the passerine ... -
Behavioral and physiological response of the passerine bird agelaioides badius to seeds coated with imidacloprid.
(Springer, 2023-09-01)Neonicotinoids are globally used insecticides, and there are increasing evidence on their negative efects on birds. This study is aimed at characterizing the behavioral and physiological efects of the neonicotinoid ... -
Carbon emissions from agricultural expansion and intensification in the Chaco
(Wiley, 2017-05)Carbon emissions from land‐use changes in tropical dry forest systems are poorly understood, although they are likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion ... -
Combined effects of agrochemical contamination and forest loss on anuran diversity in agroecosystems of east-central Argentina
(Elsevier, 2020-11)Agricultural expansion and intensification has led globally to a rapid landscape structure change and high agrochemical use resulting in habitat loss and degraded environmental quality. Co-occurrence of landscape change ... -
Concentration of current-use pesticides in frogs from the Pampa region and correlation of a mixture toxicity index with biological effects
(Elsevier, 2021-11)Contamination with current-use pesticides is frequently mentioned as a key factor in global amphibian declines although a limited number of studies have examined the mixture of pesticides accumulated by free-living frogs. ... -
Diversity and structure of bird and mammal communities in the Semiarid Chaco Region: response to agricultural practices and landscape alterations
(Imperial College London, Gran Bretaña, 2015-03)The conversion of land from natural environments to human-managed areas has been particularly pronounced in the semiarid Chaco Region. In this context, it is critical to understand the impacts that these major changes have ... -
Drivers of agricultural land - use change in the Argentine Pampas and Chaco regions
(2018-02)Agricultural expansion and intensification in South America's dry forests and grasslands increase agricultural production, but also result in major environmental trade-offs. The Pampas and Chaco regions of Argentina have ... -
Effects of the neonicotinoid insecticides Thiamethoxam and imidacloprid on metamorphosis of the toad rhinella arenarum at environmentally-relevant concentrations
(Taylor and Francis, 2023-05-22)The present study examined the acute and chronic toxicity of the neonicotinoid insecticides imidacloprid (IMI) and thiamethoxam (TIA) on the neotropical amphibian species Rhinella arenarum, Rhinella fernandezae and Scinax ... -
Fading opportunities for mitigating agriculture-environment trade-offs in a south American deforestation hotspot
(Elsevier, 2021-10)Strong trade-offs between agriculture and the environment occur in deforestation frontiers, particularly in the world's rapidly disappearing tropical and subtropical dry forests. Pathways to mitigate these trade-offs are ... -
Imidacloprid seed coating poses a risk of acute toxicity to small farmland birds: A weight-of-evidence analysis using data from the grayish baywing Agelaioides badius
(Elsevier, 2020-10)The aim of this study was to estimate the risk posed by imidacloprid (IMI) seed coating to passerine birds of the Pampa Region of Argentina using data specifically generated with the grayish baywing (Agelaioides badius). ... -
Impacts of agricultural intensification on farmland birds and risk assessment of pesticide seed treatments
(Royal Society of Chemistry, 2023-02)Agriculture is nowadays the largest driver of global environmental change, modern agricultural systems being a primary cause of biodiversity loss, including bird declines. Agricultural intensification affects bird populations ... -
Long term consumption of thiamethoxam coated seeds causes multilevel effects to the passerine Agelaiodes badius
(SETAC Latin America, 2023-09-17)Birds and pesticide treated seeds Birds and pesticide treated seedsBirds and pesticide treated seeds Birds and pesticide treated seeds -
Sensitivity analysis of the pesticide in water calculator model for applications in the Pampa región of Argentina
(Elsevier, 2020-01-01)Despite the widespread use of pesticides in the Pampa region of Argentina, mathematical models are rarely employed to predict pesticide fate due to the lack of regionally tested models and the absence of readily available ... -
Statistically based soil climate exposure scenarios for aquatic pesticides fate modelling and exposure assessment in the Pampa Region of Argentina
(Wiley, 2022-09-05)Although pesticides are used intensively in Argentina's Pampa region, the possibility of performing an environmental risk assessment (ERA) remains limited due to the absence of readily available databases to run pesticide ... -
The problem with implementing fish farms in agricultural regions: A trial in a pampean pond highlights potential risks to both human and fish health
(Elsevier, 2020-09)The safety of creating fish farms in agricultural settings was evaluated by growing Piaractus mesopotamicus in a pond, while crops where cultivated in a nearby field under a pesticide application regime typical of the Pampa ... -
Trade‐offs between biodiversity and agriculture are moving targets in dynamic landscapes
(Wiley, 2020-07)Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade‐offs between them. These trade‐offs are particularly strong in tropical and subtropical deforestation frontiers, yet ... -
