Fish , Amphibians and Reptiles Amphibians as Laboratory Animals
Amphibians include over 4,500 species within 3 major lineages---caecilians, salamanders, and anurans (Stebbins and Cohen 1995). These lineages are linked by several unique physiological traits. The most prominent is the indirect lifestyle of many amphibians--the aquatic gillbreathing larval stage and the aquatic or terrestrial lung or skin-breathing adult stage. A second feature of amphibians i...
متن کاملNatural products from the integument of nonavian reptiles.
This review describes the epidermal and glandular chemistry of nonavian reptiles in relation to proposed functions, and includes more than 170 references. The results are presented according to the different reptile taxa.
متن کاملBergmann's rule in nonavian reptiles: turtles follow it, lizards and snakes reverse it.
Bergmann's rule is currently defined as a within-species tendency for increasing body size with increasing latitude or decreasing environmental temperature. This well-known ecogeographic pattern has been considered a general trend for all animals, yet support for Bergmann's rule has only been demonstrated for mammals and birds. Here we evaluate Bergmann's rule in two groups of reptiles: cheloni...
متن کاملPhylogenomics of nonavian reptiles and the structure of the ancestral amniote genome.
We report results of a megabase-scale phylogenomic analysis of the Reptilia, the sister group of mammals. Large-scale end-sequence scanning of genomic clones of a turtle, alligator, and lizard reveals diverse, mammal-like landscapes of retroelements and simple sequence repeats (SSRs) not found in the chicken. Several global genomic traits, including distinctive phylogenetic lineages of CR1-like...
متن کاملNew resources inform study of genome size, content, and organization in nonavian reptiles.
Genomic resources for studies of nonavian reptiles have recently improved and will reach a new level of access once the genomes of the painted turtle (Chrysemys picta) and the green anole (Anolis carolinensis) have been published. Eleven speakers gathered for a symposium on reptilian genomics and evolutionary genetics at the 2008 meeting of the Society for Integrative and Comparative Biology in...
