Comparative morpho-anatomical studies of the lesions caused by citrus leprosis virus on sweet orange.

abstract：:We used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius (n=69) and L. latinasus (n=56), in order to better understand their coexistence in syntopy. Previous studies showed that the two species overlap ...
