| besnoitia in a palaearctic lizard (lacerta dugesii) from madeira. | besnoitia cysts in the heart of a lizard (lacerta dugesii) from the islands of madeira are the first record of besnoitiosis in a poikilothermic animal in the old world. the size of the cysts corresponds to those found in lizard genera (basiliscus and ameiva) from panama which belong to b. darlingi. up to now nothing is known concerning the life cycle of this species from madeira but it seems possible that cats function as definitive hosts as well as in the other species. | 1981 | 6782782 |
| lack of congruence between morphometric evolution and genetic differentiation suggests a recent dispersal and local habitat adaptation of the madeiran lizard lacerta dugesii. | genetic differentiation among nine populations of the endemic lizard lacerta dugesii milne-edwards 1829 (lacertidae) from four groups of islands constituting the archipelago of madeira, was investigated by protein electrophoresis at 23 enzyme loci. among twenty polymorphic loci, the total genetic diversity was due primarily to intra-population variation. the allele and genotypic frequencies among populations showed some heterogeneity, allowing the species to present a structuring pattern compati ... | 2001 | 11742635 |
| phylogeography of the madeiran endemic lizard lacerta dugesii inferred from mtdna sequences. | partial sequences from two mitochondrial dna genes, cytochrome b and 12s rrna, were used to assess the phylogenetic relationships of populations of lacerta dugesii from the volcanic atlantic islands of madeira, the desertas, porto santo, and the selvagens. all four-island groups are genetically distinguishable and populations within each contain similar degrees of genetic diversity. molecular clock estimates suggest that the islands were colonized much later after their emergence compared to oth ... | 2003 | 12565033 |
| role of the lizard teira dugesii as a potential host for ixodes ricinus tick-borne pathogens. | pcr screening of ticks and tissue samples collected from 151 teira dugesii lizards seems to indicate a potential role of this lizard species in the maintenance and transmission cycle of some ixodes ricinus tick-borne agents, such as rickettsia monacensis, rickettsia helvetica, and borrelia lusitaniae, that are circulating on madeira island. | 2012 | 22407681 |
| description of spinicauda dugesii sp. n. (nematoda: heterakidae) of podarcis dugesii (reptilia: lacertidae) from madeira island. | spinicauda dugesii sp. n. (heterakoidea, heterakidae), parasite of the gut of the lizard podarcis dugesii milne-edwards, 1829 (reptilia, lacertidae) from madeira island is described. males of the new species are characterized by their narrow lateral alae, and curved and very chitinized spicules of the same length: females by their thick-shelled, almost round and embryonated eggs. at the external wall of the host's gut, parasitic cysts of this nematode with immature stages inside were also observ ... | 1991 | 1937277 |
| to move or not to move: cranial joints in european gekkotans and lacertids, an osteological and histological perspective. | lepidosaurs are frequently described as having highly kinetic skulls, and different forms of cranial kinesis have been described as being characteristic of their radiation. the model of amphikinesis proposed by frazzetta, j morphol 1962; 111:287-319, which was long considered a synapomorphy of the large suborder sauria, is now much debated given its uncertain distribution among the various lizard taxa and the lack of data about its morphological correlates. in this article, we analyze the anatom ... | 2014 | 24550139 |
| iridovirus-like viruses in erythrocytes of lacertids from portugal. | icosahedral nucleo-cytoplasmic large dna viruses (ncldv)-like viruses, which forminclusions in the erythrocyte cytoplasm of reptiles, were previously presented as candidates for a new genus of the iridoviridae family. the present work describes the distribution of infected lizard hosts and ultrastructural characteristics of the viral inclusions of ncldv-like viruses from portugal and adjacent locations in spain. giemsa-stained blood smears of 235 lacerta schreiberi from portugal and spain, 571 l ... | 2013 | 23806208 |
| evolution of a centromeric satellite dna and phylogeny of lacertid lizards. | 1. the composition and phyletic distribution of a highly repetitive satellite dna, isolated from podarcis sicula, was studied. 2. this dna was rich in adenine and thymine and displayed frequent adenine stretches. it was always located on the centromeric heterochromatin even in quite taxonomically distant species. 3. southern blot hybridization of the taq i satellite on various species of lacertid families showed a close affinity among podarcis, algyroides and lacerta dugesii. 4. all the other ta ... | 1991 | 1814688 |
| structure and evolution of the mitochondrial dna complete control region in the lizard lacerta dugesii (lacertidae, sauria). | we sequenced the complete control region (cr) and adjacent trnas, partial 12s rrna, and cytochrome b (over 3100 bp) from eight individuals of madeiran wall lizards, lacerta dugesii, from four distinct island populations. the trnas exhibit a high degree of intraspecific polymorphisms compared to other vertebrates. all cr sequences include a minisatellite that varies in length between populations but is apparently fixed within them. variation in minisatellite length appears between populations sep ... | 2003 | 12569422 |
| innervation of the pancreas of the lizard lacerta dugesii (m.-edw.)studied by light, fluorescence and electron microscopy, with special regard to the acetylcholinesterase activity in the islets of langerhans. | | 1974 | 4598332 |
| questioning the proverb 'more haste, less speed': classic versus metabarcoding approaches for the diet study of a remote island endemic gecko. | dietary studies can reveal valuable information on how species exploit their habitats and are of particular importance for insular endemics conservation as these species present higher risk of extinction. reptiles are often neglected in island systems, principally the ones inhabiting remote areas, therefore little is known on their ecological networks. the selvagens gecko tarentola (boettgeri) bischoffi, endemic to the remote and integral reserve of selvagens archipelago, is classified as vulner ... | 2020 | 31915567 |
