| [electron microscopic study of the penetration and distribution of somitic cells in the mesoblast of the limb buds of reptiles (anguis fragilis and lacerta viridis)]. | based on characteristics of mitochondria and on the amount of lipid inclusions, a distinction between somitic cells and mesoblastic somatopleural cells is possible, at the early stages of the development of the limb bud in reptiles (anguis fragilis and lacerta viridis). the dislocation of the ventral processes of the somites and the localisation of the somitic cells in the mesoblast of the anterior limb buds could be studied. | 1988 | 172253 |

| first record of neoxysomatium brevicaudatum through the non-invasive sampling of anguis fragilis: complementary morphological and molecular detection. | relatively few studies have examined the parasite fauna of british reptiles, partly due to the cryptic nature and low population density of these hosts. here we examined 12 populations of the slow worm anguis fragilis which, unlike other uk lizards, occurs at locally high population densities. morphological examination of non-invasively collected faecal samples revealed the presence of neoxysomatium brevicaudatum and a second unidentified nematode species. although previously unrecorded from slo ... | 2011 | 21554834 |
| parasitic helminths of reptiles (reptilia) in south moravia (czech republic). | an helminthological investigation of 104 reptile species was carried out in south moravia (czech republic). we examined lacerta viridis, l. agilis, anguis fragilis, natrix natrix, coronella austriaca and vipera berus. twelve species of parasites were found. among these, nematoda occurred most often, followed by trematoda and cestoda. no acanthocephala were detected. | 2005 | 15565461 |

| morphological and kinematic study of the tongue and buccal cavity in the lizard anguis fragilis (reptilia:anguidae). | the ability to detect chemical cues is highly developed in scleroglossa, and particularly in anguid lizards. this ability was predicted because anguids possess a well-developed vomeronasal organ (vno) (or jacobson's organ) and rely largely on chemical cues in various behaviours as other active foragers. in this work, we have investigated the possible functional association between tongue flicking and the vno in the lizard anguis fragilis. | 1994 | 7825739 |

| contrasting evolutionary histories of the legless lizards slow worms (anguis) shaped by the topography of the balkan peninsula. | genetic architecture of a species is a result of historical changes in population size and extent of distribution related to climatic and environmental factors and contemporary processes of dispersal and gene flow. population-size and range contractions, expansions and shifts have a substantial effect on genetic diversity and intraspecific divergence, which is further shaped by gene-flow limiting barriers. the balkans, as one of the most important sources of european biodiversity, is a region wh ... | 2016 | 27165497 |
| new data on the structure and the growth of the osteoderms in the reptile anguis fragilis l. (anguidae, squamata). | light and electron microscopy shows the osteoderms of anguis fragilis to be small, flat disks located in the dermis along the adult trunk: microradiography established the extent of the mineralization. each osteoderm coincides exactly with an epidermal fold forming the keratinized scales characteristic of the skin of reptiles. sections perpendicular to the surface show two mineralized layers differing in histological and histochemical characteristics and in fine structure, although both contain ... | 1985 | 29991191 |
