| selection, drift, and introgression shape mhc polymorphism in lizards. | the major histocompatibility complex (mhc) has long served as a model for the evolution of adaptive genetic diversity in wild populations. pathogen-mediated selection is thought to be a main driver of mhc diversity, but it remains elusive to what degree selection shapes mhc diversity in complex biogeographical scenarios where other evolutionary processes (e.g. genetic drift and introgression) may also be acting. here we focus on two closely related green lizard species, lacerta trilineata and l. ... | 2019 | 30258107 |
| the first miocene fossils of lacerta cf. trilineata (squamata, lacertidae) with a comparative study of the main cranial osteological differences in green lizards and their relatives. | we here describe the first fossil remains of a green lizard of the lacerta group from the late miocene (mn 13) of the solnechnodolsk locality in southern european russia. this region of europe is crucial for our understanding of the paleobiogeography and evolution of these middle-sized lizards. although this clade has a broad geographical distribution across the continent today, its presence in the fossil record has only rarely been reported. in contrast to that, the material described here is a ... | 2019 | 31433807 |
| neurogenesis in reptilian cortical structures: 3h-thymidine autoradiographic analysis. | histogenesis was studied in forebrain cortical areas of two reptiles, emys orbicularis and lacerta trilineata, by using tritiated thymidine autoradiography. four areas were considered: the dorsomedial, the general (dorsal), and the lateral cortices, and the dorsal ventricular ridge (dvr). the bulk of neurogenesis in these four pallial fields proceeds within a short period of 8-9 days, between developmental stages 15 and 18 in emys and stages 32-34 in lacerta. lateral-to-medial as well as anterio ... | 1986 | 3950076 |
