Huge but moderately long-lived: age structure in Leptodactylus fallax, a critically endangered frog from Montserrat, West Indies.
No full textWe applied skeletochronological methodology to assess the age and growth in one of the largest living anurans, the mountain chicken, Leptodactylus fallax. We compared bone cross-sections obtained from wild animals, found dead in 2009 after the chytrid outbreak occurred in Montserrat, and captive individuals part of the breeding program at Jersey Zoo. Lines of arrested growth (LAGs) were visible in both groups. Individuals reared in captivity reached an older age than their wild counterparts. Additionally, at the same age, captive males were larger than captive females and wild females were much larger than captive females. A literature screening of age and snout-vent length (SVL) for 46 species (including L. fallax) ascribed to seven families (Bufonidae, Dicroglossidae, Leptodactylidae, Mantellidae, Microhylidae, Ranidae, and Rhacophoridae) showed that the largest species were also the most long-lived. Nevertheless, the position of L. fallax was an outlier (reaching a maximum documented SVL of 280 mm and a maximum longevity of 9 years) in respect to the other species considered. Its body size was larger than expected, indicating a case of gigantism most probably associated with adaptation to an insular environment
Giant and long-lived: age structure in Macroscincus coctei, an extinct skink from Cape Verde.
No full textThe age structure of the extinct giant Cape Verde skink Macroscincus coctei was studied using skeletochronology applied to 11 preserved males, 15 females, and one juvenile, collected at the end of the 19(th) century. Counts of lines of arrested growth (LAGs) indicated that in this species - which lived on islets with extreme natural conditions (e.g., hard aridity, lack of rainfall) - the maximum life span was estimated as 16 years for males and 12 years for females; the single juvenile was 4 years old. Although the sexes had similar mean ages, mean body length of males was significantly higher than that of females (283 versus 255 mm). There was no clear relationship between body length and estimated age, although the largest males were also the oldest. The analysis of LAGs revealed a sexual difference in growth rates, males reaching greater size earlier than females
