Coping with Aridity: Life History of Chacophrys pierottii, a Fossorial Anuran of Gran Chaco

摘要: We studied size, age, and growth in Chacophrys pierottii, a fossorial amphibian inhabiting the arid region of Gran Chaco, northern Argentina. provide first detailed demographic data for this cryptic species using skeletochronology. observed female-biased sexual size dimorphism but no differences age parameters between two sexes. pierottii has short life span up to 5 a, both males females reaching maturity after 1 a. Our results suggest that rapid followed by relatively reproductive lifespan is response constraints posed environments. The history population C. are line with patterns other anurans xeric habitats. study provides conservation managers basic required accurate assessment status adoption proper strategies.
