Complete genome sequence of a divergent strain of Tibetan frog hepatitis B virus associated with a concave‑eared torrent frog (Odorrana tormota)
(Springer, 2019-06)Viruses of the family Hepadnaviridae are characterized by partially dsDNA circular genomes of approximately 3.2 kb, which are reverse transcribed from RNA intermediates. Hepadnaviruses have a broad host range, which includes ... -
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. ... -
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 ... -
Frog body condition: Basic assumptions, comparison of methods and characterization of natural variability with field data from Leptodactylus Latrans
(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
(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 ... -
Integration of a battery of biomarkers to evaluate the health status of field-collected frogs of Leptodactylus luctator living in ecosystems with different anthropogenic disturbances
(Elsevier, 2024-07-10)Amphibians are the most threatened group of vertebrates because they have certain biological and ecological characteristics that make them sensitive to environmental changes. The aim of this study was to evaluate the health ... -
Multiple Level Effects of Imazethapyr on Leptodactylus latinasus (Anura) Adult Frogs
(Springer, 2021-08)Imazethapyr is an herbicide that is used in a variety of crops worldwide, including soybean and corn. The aim of the present study was to evaluate the biomarkers responses of adult Leptodactylus latinasus exposed to the ... -
Realistic scenarios of pesticide exposure alters multiple biomarkers in BOANA PULCHELLA (ANURA) Adult Frogs
(Springer, 2023-03-01)Imazethapyr, a post-emergent herbicide used in worldwide soybean and corn crops, induces genetic and biochemical alterations in aquatic vertebrates. This study examined the relationship between biomarkers at different ...
