Lithobates Catesbeianus

La especie rana toro está en la lista de las 100 especies invasoras más dañinas del mundo. Su dieta generalista y la capacidad de alimentarse de cualquier especie de menor tamaño permite que impacte negativamente a poblaciones nativas de anfibios. Existen numerosos estudios de composición dietética de la especie a nivel internacional, sin embargo, escasos trabajos se han realizado a nivel nacional. El presente estudio, tiene el objetivo de determinar la composición dietética de la especie L. catesbeianus en Isla Santay en Ecuador, para lo cual se capturaron 14 especímenes adultos durante los meses de septiembre a diciembre en los años 2018 y 2019. Los resultados evidencian que la dieta es predominada por los órdenes: Characiformes, Coleoptera, Hymenoptera y Decapoda. Es posible que la rana toro en la isla Santay impacte negativamente a la especie de anfibio nativa Leptodactylus labrosus, a través de la competencia (solapamiento de la dieta).

This study evaluated the effects of [d-Leu1]Microcystin-LR variant by the exposure of Lithobates catesbeianus tadpole to unialgal culture Microcystis aeruginosa NPLJ-4 strain. The Tadpole was placed in aquariums and exposed to Microcystis aeruginosa culture or disrupted cells. For 16 days, 5 individuals were removed every 2 days, and tissue samples of liver, skeletal muscle, and intestinal tract were collected for histopathology and bioaccumulation analyses. After exposure, those surviving tadpoles were placed in clean water for 15 days to evaluate their recovery. A control without algae and toxins was maintained in the same conditions and exhibited normal histology and no tissue damage. In exposed tadpoles, samples were characterized by serious damages that similarly affected the different organs, such as loss of adhesion between cells, nucleus fragmentation, necrosis, and hemorrhage. Samples showed signs of recovery but severe damages were still observed. Neither HPLC-PDA nor mass spectrometry analysis showed any evidence of free Microcystins bioaccumulation.
