Biomarcadores hematológicos del sapo común Bufo (Rhinella) arenarum en ecosistemas alterados de la provincia de CórdobaHematologic biomarkers of the common toad Bufo arenarum in altered ecosystem of Córdoba province
(Asociación Toxicológica Argentina, 2015-08)
El uso de biomarcadores hematológicos es importante para poder evaluar riesgos ambientales y la exposición a sustancias químicas potencialmente tóxicas y así poder desarrollar medidas que sirvan como señales de alarma ...
Potential involvement of C3 complement factor in amphibian fertilization
(Elsevier Science Inc, 2000-09)
We have assessed the potential involvement of C3, the third complement factor, and its receptor in Bufo arenarum fertilization. We show that a polyclonal antibody against a B. arenarum C3-like factor (C3Ba) reacts specifically ...

Larval development and metamorphosis of the olfactory and vomeronasal organs in the toad Rhinella (Bufo) arenarum (Hensel, 1867)
(Wiley, 2010-07)
The olfactory and the vomeronasal system are the two major chemosensory systems found in terrestrial vertebrates. Among tetrapods, amphibians are unique in having an aquatic larval stage, followed by metamorphosis to a ...
Teratogenic effects of carcinogen implantation in a regenerative field in Bufo arenarum tadpoles
(Wiley, 1973)
Implantation of 20‐methylcholanthrene (MC), 3,4 benzopyrerne (BP), and 7,12‐dimethylbenz [a] anthracene in the tail of Bufo arenarum tadpoles induced toratogenic effects as well as lymphocyte or pleomorphic cell nodule ...
Hypophyseal functions in the toad Bufo arenarum Hensel
(Chicago University Press, 1949-03)
The study of the functions of the hypophysis of Bufo arenarum Hensel (and other batrachians) was started forty years ago in Argentina. This toad is perhaps the species in which the largest number of functions related to ...
Determinants of Instrumental extinction in terrestrial toads (Bufo arenarum)
(Elsevier, 2006-11)
Previous research in a water-reinforced instrumental training situation with toads (Bufo arenarum) has shown that performance in both acquisition and extinction is poorer after partial, rather than continuous reinforcement ...
