| histopathology, molecular identification and antifungal susceptibility testing of nannizziopsis arthrosporioides from a captive cuban rock iguana (cyclura nubila). | chrysosporium-related fungi, the cause of superficial and deep mycoses, are an emerging infectious disease affecting not only reptiles but also immunocompromized humans. however, the information on nannizziopsis arthrosporioides is extremely scarce. we herein characterized n. arthrosporioides isolated from a cuban rock iguana (cyclura nubila). three skin ulcers were found in a cuban rock iguana after captivity for 8 years. microscopic examination revealed hyperplastic, hyperkeratotic, and ulcera ... | 2020 | 32794052 |
| heterozygosity-fitness correlations reveal inbreeding depression in neonatal body size in a critically endangered rock iguana. | inbreeding depression, though challenging to identify in nature, may play an important role in regulating the dynamics of small and isolated populations. conversely, greater expression of genetic load can enhance opportunities for natural selection. conditional expression concentrates these opportunities for selection and may lead to failure of detection. this study investigates the possibility for age-dependent expression of inbreeding depression in a critically endangered population of rock ig ... | 2019 | 31617903 |
| conditional female strategies influence hatching success in a communally nesting iguana. | the decision of females to nest communally has important consequences for reproductive success. while often associated with reduced energetic expenditure, conspecific aggregations also expose females and offspring to conspecific aggression, exploitation, and infanticide. intrasexual competition pressures are expected to favor the evolution of conditional strategies, which could be based on simple decision rules (i.e., availability of nesting sites and synchronicity with conspecifics) or on a foc ... | 2020 | 32273999 |
| capillary and mitochondrial unit in muscles of a large lizard. | we asked whether capillaries and mitochondria form a structural and functional unit in the musculature of the cuban iguana (cyclura nubila) similar to that found in mammals. we found a significant correlation between capillary length density [jv(c, f)] and mitochondrial volume density [vv(mt, f)] of the musculature with a slope that revealed that on average 3.5 km of capillaries were associated with each milliliter of mitochondria (vs. approximately 11 km/ml in mammals). these capillaries had a ... | 1989 | 2705584 |
| heart mitochondrial properties and aerobic capacity are similarly related in a mammal and a reptile. | the heart mitochondrial properties and the aerobic capacity (vo2max) of the rat (sprague-dawley breed) and the cuban iguana (cyclura nubila) were used to evaluate the relationship between the oxidative capacity of the heart and the maximum oxygen delivery rate. both species are active at body temperatures of 37-39 degrees c, have similar heart mitochondrial volumes [vmt; 0.43 +/- 0.02 ml (s.e.m.) in the rat and 0.48 +/- 0.02 ml in the iguana] and differ less than twofold in vo2max (29.2 +/- 1.6 ... | 1995 | 7714455 |
