“…This may reflect the presence of cryptic species within C. siamensis, as in the cases of some squamate morpho-species (e.g. King 1983, Ota et al 1998). This issue needs serious attention in the context of biodiversity conservation, because all wild populations of C. siamensis are critically endangered (Hilton-Taylor 2000), and some translocation and re-introduction programmes are currently under way (e.g.…”

Molecular structures of centromeric heterochromatin and karyotypic evolution in the Siamese crocodile (Crocodylus siamensis) (Crocodylidae, Crocodylia)

Crocodilians have several unique karyotypic features, such as small diploid chromosome numbers (30-42) and the absence of dot-shaped microchromosomes. Of the extant crocodilian species, the Siamese crocodile (Crocodylus siamensis) has no more than 2n = 30, comprising mostly bi-armed chromosomes with large centromeric heterochromatin blocks. To investigate the molecular structures of C-heterochromatin and genomic compartmentalization in the karyotype, characterized by the disappearance of tiny microchromosomes and reduced chromosome number, we performed molecular cloning of centromeric repetitive sequences and chromosome mapping of the 18S-28S rDNA and telomeric (TTAGGG)( n ) sequences. The centromeric heterochromatin was composed mainly of two repetitive sequence families whose characteristics were quite different. Two types of GC-rich CSI-HindIII family sequences, the 305 bp CSI-HindIII-S (G+C content, 61.3%) and 424 bp CSI-HindIII-M (63.1%), were localized to the intensely PI-stained centric regions of all chromosomes, except for chromosome 2 with PI-negative heterochromatin. The 94 bp CSI-DraI (G+C content, 48.9%) was tandem-arrayed satellite DNA and localized to chromosome 2 and four pairs of small-sized chromosomes. The chromosomal size-dependent genomic compartmentalization that is supposedly unique to the Archosauromorpha was probably lost in the crocodilian lineage with the disappearance of microchromosomes followed by the homogenization of centromeric repetitive sequences between chromosomes, except for chromosome 2.

Agamid lizards (Agamidae, Acrodonta, Sauria, Reptilia) of Vietnam

2007

Being a hotspot of plant and animal diversity and endemism, Vietnam is important for the conservation of biodiversity on a global scale. It is one of the most threatened areas in tropical Asia in terms of destruction of tropical rain forest as an environment with a unique Vietnamese fauna. Previous summaries on Vietnamese agamids, their taxonomy and distribution were published in the works of Bourret 1943, Nguyen & Ho 1996, Bobrov 1995, Ziegler 2002and Ziegler et al. 2006. New, intensive study of the fauna of Vietnam as well as new opportunities offered by molecular methods make clear that taxonomic diversity in Southeast Asia is underestimated. The aim of this paper is to show and review the taxonomic diversity of different evolutionary lineages of agamids and their geographical distribution. This is based on new results of the authors and most recent evaluation of literature sources.

Asian Agamid lizards (Agamidae, Acrodonta, Sauria, Reptilia): Phylogenetic and taxonomic diversity The Southeast Asian-Indonesian and Australian-New Guinean tectonic plates have both been hypothesized to be centers of origin of agamid lizards (Moody, 1980). The Asian continent housed a number of hotspots of plant and animal diversity and endemism, important for the conservation of biodiversity on a global scale. There are many threatened areas in tropical Asia in terms of destruction of tropical rain forest as an environment with a unique biota and herpetofauna in particular. New intensive studies of the Asian fauna as well as new opportunities offered by molecular methods make it clear that taxonomic diversity is underestimated, especially in South and Southeast Asia. The aim of this paper is to show the taxonomic diversity of different evolutionary lineages and the distribution of agamids by sub region in Asia. We compare several Asian territories well studied in diversity of agamids:
