TITLE:
Population size and conservation genetics of the endangered rock iguana, {iCyclura rileyi}
ABSTRACT:
Iguanas of the genus {iCyclura} are among the largest and most endangered lizards in the world.
Demographics of the rock iguana {iC. rileyi}, with its three subspecies located on widely separated islands, are poorly known. {iCyclura r. cristata} is restricted to a single cay in the southern Exumas; {iC. r. nuchalis} exists on two cays in the Acklins Bight; and {iC. r. rileyi} is found on seven tiny cays in and around San Salvador, Bahamas. We have begun a systematic study of population size, body size and genetic variability of all populations of the species. Most populations are small, isolated, and coexist with introduced fauna. Body size varies among populations and may be influenced by nutrition availability. Genetic variability was surveyed using 96 RAPD-PCR primers. Only 14 (2.0%) of the amplified 672 putative loci provided scoreable heterozygosity. Band analysis from the seven {iC. r. rileyi} populations indicated significant population sub structuring and low heterozygosity. To date no unique alleles have been found among any of the 10 sub specific populations. We have begun micro satellite DNA analysis to provide codominate measures of heterozygosity for all populations. Conservation priorities are discussed in light of our data.

TITLE:
Morphometric and genetic comparisons between feral and farm populations of tilapias (iSarotherodon spp) in Java, Indonesia.
ABSTRACT:
Tilapia fishes are important protein source for Indonesians.(iSarotherodon niloticus) is particularly selected for farming as it relatively grows faster and bigger in size, while (iS. mossambicus) is not domesticated and left in the wild. However, tilapia species are readily hybridize with each other, and therefore the purity of (iS. niloticus) is always doubted. Morphometric, isozyme and random amplified polymorphic DNA (RAPD) analysis of (iS. niloticus) and (iS. mossambicus) were conducted to determine the species boundaries between these two species. The data will also be used to estimate the amount of introgression that has occurred. Data analysis for (iS. mossambicus) showed morphometric differences among the populations which appeared to be environmentally induced. Isozyme and RAPD analysis for this species showed significant population differentiation (G-st = 0.067; 2 = 30.15; p < 0.01 and G-st = 0.217; 2 = 38.95; p < 0.01 and average D of 0.005 and 0.136, respectively), possibly due to the founder effect. We have begun the data analysis for (iS. niloticus) in order to meet the objectives of this study.
