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
Brodeur, Celine Marie Julie; Sanchez, Marisol; Castro, Luciana; Cristos, Diego Sebastian; Rojas, Dante Emanuel; Damonte, María Jimena; Poliserpi, María Belén; D'Andrea, María Florencia; Andriulo, Adrian Enrique (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
Suarez, Romina Paula; Zaccagnini, Maria Elena; Babbitt, Kimberly J.; Calamari, Noelia Cecilia; Natale, Guillermo Sebastian; Cerezo, Alexis; Codugnello, Nadia; Boca, Rosa Teresa; Damonte, María Jimena; Vera Candioti, Josefina; Gavier Pizarro, Gregorio Ignacio (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: ... -
Concentration of current-use pesticides in frogs from the Pampa region and correlation of a mixture toxicity index with biological effects
Brodeur, Julie Céline; Damonte, María Jimena; Rojas, Dante Emanuel; Cristos, Diego Sebastian; Vargas, Claudia; Poliserpi, Maria Belen; Andriulo, Adrian Enrique (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. ... -
Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus Latrans
Brodeur, Celine Marie; Damonte, María Jimena; Vera Candioti, Josefina; Poliserpi, Maria Belen; D´andrea, María Florencia; Bahl, María Florencia (2020-01-08)Body weight and snout-vent length (SVL) data of 3006 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best approach for expressing body condition ... -
Frog somatic indices: Importance of considering allometric scaling, relation with body condition and seasonal variation in the frog Leptodactylus latrans
Brodeur, Celine Marie; Vera Candioti, Josefina; Damonte, María Jimena; Bahl, Maria Florencia; Poliserpi, Maria Belen; D´andrea, María Florencia (Elsevier, 2020)Snout-vent length (SVL) and liver, gonad, fat bodies and carcass weight data from 661 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region of Argentina were analyzed to evaluate the best ...
