carnosine in the brain and olfactory system of amphibia and reptilia: a comparative study using immunocytochemical and biochemical methods.the pattern of distribution of carnosine-like immunoreactivity and its relation to glial fibrillary acidic protein immunoreactivity have been studied in two lizards (gallotia galloti and tarentola delalandii) and in two anuran amphibians (rana esculenta and xenopus laevis) using immunocytochemical techniques. biochemical data obtained by paper electrophoresis show that the dipeptides carnosine and homocarnosine are both present in the brain of all the species examined. in the central nervous sys ...19911795878

phylogeography and natural selection in the tenerife gecko tarentola delalandii: testing historical and adaptive hypotheses.combining phylogeographic and matrix correspondence approaches in the analysis of geographical variation provides a fruitful approach to inferring the causes of molecular and morphological evolution within species. here we present a study on the gecko tarentola delalandii on the island of tenerife, canary islands, which provides an outstanding model of an exceptionally high degree of phylogeographic differentiation in magnitude and pattern on a small spatial scale. we reconstruct the population ...200010972761
the dynamics of genetic and morphological variation on volcanic islands.oceanic archipelagos of volcanic origin have been important in the study of evolution because they provide repeated natural experiments allowing rigorous tests of evolutionary hypotheses. ongoing volcanism on these islands may, however, affect the evolutionary diversification of species. analysis of population structure and phylogeographic patterns in island populations can provide insight into evolutionary dynamics on volcanic islands. we analysed genetic and morphological variation in the geck ...200515870037
