“…This tendency has been pointed out by many previous authors (Halliday and Verrell, 1988;Guarino et al, 1998;Tinsley and Tocque, 1995). Shine (1979) reported females were larger than males in more than 90% of 589 anuran species he studied.…”

“…This is the first indication of longevity in R. nigrovittata in nature. Longevity observed in the other tropical species M. microtympanum was seven yrs (Guarino et al, 1998). Longevities of these two tropical species seem to be shorter than those of some temperate species such as Bufo bufo (12 yrs : Hemelaar, 1988) and Bombina variegata (11-14 yrs: Plytycz and Bigaj, 1993).…”

“…In the case of Mantidactylus microtympanum, a single tropical species by now examined, LAGs are reported to be formed by the harsh annual period, with decreasing temperature, rainfall, and available food (Guarino et al, 1998). On the other hand, LAGs of Bufo pentoni living in the subdesert are considered to be formed by a long aestivation (Barbault et al, 1979), and LAGs Geocrinia alba and G. vitellina are similarly estimated to be formed during the dry months (Driscoll, 1999).…”

“…Most of previous skeletochronological studies have ever been conducted in species from temperate regions, such as, Bufo bufo (Hemelaar, 1988), Bufo calamita (Denton and Beebee, 1993), Rana sylvatica (Bastein and Leclair, Jr., 1992), Rana tagoi (Kusano et al, 1995a), and Rana sakuraii (Kusano et al, 1995b). Much smaller numbers of studies have been made for desert species such as Bufo pentoni (Barbault et al, 1979) and Scaphiopus couchii (Tinsley and Tocque, 1995), and only a single study dealt with a mantellid, Mantidactylus microtympanum from the tropical rain forest of Madagascar (Guarino et al, 1998). Thus no studies have ever been made for amphibians from Asian tropics.…”

Age Determination by Skeletochronology of Rana nigrovittata, a Frog from Tropical Forest of Thailand

2000

ABSTRACT-Age in 96 individuals of a tropical frog Rana nigrovittata from Thailand was skeletochronologically investigated. Hematoxylinophilic lines interpreted as lines of arrested growth (LAGs) were observed clearly in the periosteal bone suggesting that this technique can be used to estimate the age of frogs from tropical Asia. The maximum age observed was nine years in males and six in females, but age structure did not differ significantly between the sexes. In the same age class, males were significantly larger than females.

“…Our previous studies demonstrated the applicability of skeletochronology to tropical amphibians and reptiles, and provided further evidence on the utility of this method in assessing natural history traits (GuarIno et al 1998, andreone & GuarIno 2003. This is confirmed by the present study on F. pardalis¸ for which we were able to detect the lines of arrested growth.…”

The morphometry, age structure, and abundance of the panther chameleon Furcifer pardalis (Cuvier 1829) were studied at Nosy Be (NW Madagascar). Males were larger and heavier than females (SVL, 138.38 ± 35.94 vs 91.92 ± 18.48 mm; mass, 61.06 ± 39.86 vs 22.62 ± 13.17 g). The age, assessed by skeletochronology, was usually less than one year, with a maximum of 2 years. The density estimate for adult individuals was higher along roads (42.21/ha) than in agricultural habitats far from roads (17.43/ha). Compared to other species of Malagasy chameleons, F. pardalis is infrequent in pristine and close forests, while, like other Furcifer species, it is more closely associated with riverine habitats. The higher concentration of individuals in forest-like bands along roads is explained by the presence of a suitable vegetation band along roads and the similarity of this habitat to the riverine and ecotonal forests preferred by chameleons of the genus Furcifer. The life history traits, high fecundity and short life span indicate that the current collecting rate does not affect the abundance of F. pardalis. Measures of chameleon conservation at Nosy Be should consider the preservation of the anthropogenic forest band.

Differentiation and development of long bones were studied in European water frogs: Rana lessonae, R. ridibunda, and R. esculenta. The study included premetamorphic larvae (Gosner Stage 40) to frogs that were 5 years old. Femora, metatarsal bones, and proximal phalanges of the hindlimb exhibit the same pattern of periosteal bone differentiation and the same pattern of growth. Longitudinal and radial growth of these bones was studied by examination of the diaphyses and epiphyses, particularly where the edge of periosteal bone is inserted into the epiphysis. The periosteum seems to be responsible for both longitudinal and radial growth. Investigation of the formation, length, and arrangement of lines of arrested growth reveals that the first line is present only in the middle 25-35% of the length of the diaphysis of an adult bone; therefore, only the central portion of the diaphysis should be used for age estimation in skeletochronological studies. Comparison of the shapes and histological structures of epiphyses in the femur, metatarsal bones, and phalanges revealed that epiphyseal cartilages are composed of an inner and outer part. The inner metaphyseal cartilage has distinct zones and plugs the end of the periosteal bone cylinder; its role in longitudinal growth is questioned. The outer epiphyseal cartilage is composed of articular cartilages proper, in addition to lateral articular cartilages. Differences in the symmetry of the lateral articular cartilages of distal epiphyses of the femur and toes may reflect adaptations to different kinds of movements at the knee and in the foot.
