Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus latrans

Ecological Indicators, Journal Year: 2020, Volume and Issue: 112, P. 106098 - 106098

Body weight and snout-vent length (SVL) data of 3006 individual Leptodactylus latrans frogs collected over ten years in the Pampa Region Argentina were analyzed to evaluate best approach for expressing body condition characterize natural variability this parameter. Two different methods compared: scaled mass index (SMI) residuals methods. L. was related SVL through an allometric relationship described by power function: Y = 0.00006 X3.11. The shape weight-length not affected neither sex animal nor its date or site capture. A truly size-independent SMI value more easily obtained when defining scaling exponent a non-linear regression on rather than performing standardized major axis lnweight lnlength.

Atrazine characterization: An update on uses, monitoring, effects, and environmental impact, for the development of regulatory policies in Argentina

Integrated Environmental Assessment and Management, Journal Year: 2022, Volume and Issue: 19(3), P. 684 - 697

Atrazine (ATZ) is the third most widely used herbicide in Argentina (10 000 t year-1 ) and approved for sugar cane, flax, corn, sorghum, tea. An assessment of ATZ environmental impacts was conducted at request Ministry Environment Sustainable Development Argentina. A review 541 national international technical scientific reports a survey among agricultural technicians, applicators, producers done. The revealed that 94% applications are terrestrial use diversion exists, associated mainly with soybean cultivation. reported high frequencies (50%-100%) surface groundwater, sediments, soils, sometimes exceeding permitted limits. Several sublethal effects induced by on invertebrate vertebrate species were found, concentrations lower than those water quality guidelines (<3 µg L-1 or found Available epidemiological human health studies local populations extremely scarce. This also demonstrated herbicides ubiquitous environment. investigation highlights need further assessing adverse species, ecosystems, health. Therefore, precautionary principle recommended to promote better application standards product traceability reduce volumes entering environment avoid deviation. In addition, this work concluded there reviewing toxicological classification, establishing buffer zones application, introducing specific management guidelines, expanding toxicity, ecotoxicity, epidemiology risk assessments. study could serve as preliminary evaluation final regulatory action considering inclusion Annex III Rotterdam Convention.
