    ABSTRACT: We assessed the reproductive ecology of the American crocodile (Crocodylus acutus) on Coiba Island, Panama from January–December 2013. We examined nest site characteristics from January–April and hatchling survivorship from April–December. Ten nests were examined at three nesting localities where 30% of the nests were found under forest canopies and 70% were exposed to sunlight (distance to nearest tree = 280 ± 110 cm). Half of the nests were built closer to the sea and the other half closer to bodies of freshwater (700 ± 360 cm). The nest dimensions were 17.5 ± 7.8 cm from the top of the clutch to the surface, 2.9 ± 9.9 cm from the bottom of the clutch to the surface, and 35.9 ± 3.6 cm wide at the top of the nest cavity. The average soil conditions in the nests consistently had high concentrations of potassium (69.3 mL/L) and manganese (9.2 mg/L), moderate concentrations of phosphorus (6.6 mg/L) and iron (3.7 mg/L), and low concentrations of zinc (0.5 mg/L) and copper (0.0 mL/L). Cation exchange capacity showed consistently high concentrations of calcium (2.2 cmol/kg), moderate of magnesium (1.1 cmol/kg), and low in aluminum (0.1 cmol/L). Volumetric water content was about 25.0 ± 2.6% at the bottom and 22.8 ± .3% in the middle of the clutches. Hatching success was 88.9%, of which 68.3% hatched by themselves or with the mother’s aid and 20.6% hatched with our aid. Mean size of the mother was 219 ± 6.2 cm total length (TL) and 115.9 ± 3.0 cm snout–vent length (SVL). The incubation period was estimated to be 85–88 days. TL and SVL growth rate of those individuals were 0.03–0.16 cm/day and 0.00–0.09 cm/day, respectively. Population size was estimated to be 218.6 hatchlings in 22.4 km2; the hatchling population declined 65.7% after the first 2 months (May and June) and 95.9% by July, leaving only 0.5% remaining by December. This is the first study to assess nest-site characteristics and estimate hatchling survival in a Pacific population of American crocodiles.

    ABSTRACT: Parasites can significantly influence the health of the host by inhibiting important physiological and behavioral processes. Some factors like body size, age of host, sex, and season can influence parasite load in nature. Mites are ectoparasites that can occur in lizards, possibly having a negative impact on their host. Our goals were to identify the mite that infested the Neotropical lizard Liolaemus pacha and describe its anatomical distribution, evaluate if mite intensity affected lizard mass, assess the relationship between lizard body size and mite intensity, and calculate the prevalence and intensity of mites in these lizards, comparing males and females and the reproductive and non-reproductive seasons. We analyzed preserved specimens and also studied lizards in their natural environment. We performed linear regression analyses between the intensity of mite infestation and snout-vent length and between lizard mass and intensity of mite infestation. To compare the intensity of mite infestation between sex and season, we used the Mann-Whitney Test. The mite was identified as a species of Pterygosoma Peters, 1849 (Prostigmata: Pterygosomidae). Mite infestation was mainly in the ventral area, particularly in the gular and lateral regions. Lizard body size did not explain the intensity of mite infestation, nor was lizard mass influenced by the intensity of mite infestation. Males in their natural habitat presented, on average, more mites than females, which might be related to differences in behavior. There were no differences between seasons. This study constitutes the second Argentine record of the presence of the ectoparasite Pterygosoma sp. in a Liolaemus species and the first that explores its relation to ecological parameters.
