microsatellites in the sand lizard (lacerta agilis): description, variation, inheritance, and applicability.	we developed microsatellite markers for the sand lizard (lacerta agilis) to enable investigations of the genetic variability within and among populations with a heterogeneous spatial distribution in sweden. the populations, which could not be characterized by variation in allozymes or mitochondrial dna, had a substantial level of variability in microsatellite loci. however, the variability in swedish populations was limited compared to a large, outbred hungarian population. in the sand lizard, t ...	1997	9435947
paternal genotype influences incubation period, offspring size, and offspring shape in an oviparous reptile.	theoretical models for the evolution of life-history traits assume a genetic basis for a significant proportion of the phenotypic variance observed in characteristics such as hatching date and offspring size. however, recent experimental work has shown that much of the phenotypic variance in hatchling reptiles is induced by nongenetic factors, such as maternal nutrition and thermoregulation, and the physical conditions experienced during embryogenesis. thus, there is no unambiguous evidence for ...	1996	28565274
does reproductive success increase with age or with size in species with indeterminate growth? a case study using sand lizards (lacerta agilis).	most data on determinants of reproductive success (rs) and reproductive "tactics" are correlational in nature, and hence cannot be used to infer causation. consistent patterns-such as an increase in rs with age, as seen in many types of organisms-may result from diverse underlying mechanisms. ontogenetic increases in rs in mammals and birds may be due largely to direct effects of age (via learning, etc.) but our analyses show that apparently analogous ontogenetic shifts in reproductive tactics a ...	1996	28307079
phylogenetic relationships among phrynosomatid lizards as inferred from mitochondrial ribosomal dna sequences: substitutional bias and information content of transitions relative to transversions.	the phylogenetic relationships among 40 species, representing all genera, within the north american lizard family phrynosomatidae were inferred from mitochondrial ribosomal rna gene sequences. cladistic analysis of the dna sequence data (779 bp; 162 informative characters) supported the monophyly of the sand lizards (callisaurus, cophosaurus, holbrookia, and uma), petrosaurus, phrynosoma, urosaurus, and uta. all the species of sceloporus, except s. variabilis and s. chrysostictus, formed a clade ...	1995	7663765
[the morphofunctional characteristics of the interstitial endocrinocytes (leydig cells) of the testes in vertebrates under conditions of seasonal change in reproductive activity].	by means of light and electron microscopy the structural organization of leydig cells was studied in rana ridibunda, lacerta agilis, columba livia in the periods of reproductive activity and reproductive break. the dynamics of structural changes of some parameters of the testicles (interstitial tissue square, endocrinocytes number, state of the cytoplasm, structural components and the volume of nuclei) was shown in the process of the reproductive activity seasonal changes. nuclear volume and the ...	1995	8688941
similar localization of immunoreactive glutamate and aspartate in the pineal organ and retina of various nonmammalian vertebrates.	the localization of immunoreactive glutamate and aspartate was compared in the pineal organ and retina of various vertebrates (raja clavata, carassius auratus, salvelinus alpinus, triturus vulgaris, triturus cristatus, lacerta muralis, lacerta agilis, lacerta viridis, columbia livia and white leghorn chicken) by postembedding immunoelectron microscopy. immunoreaction of both excitatory amino acids was detected in the pinealocytes in a localization similar to that of retinal photoreceptors. the r ...	1995	8714767
monoaminergic innervation patterns in the anterior dorsal ventricular ridge of a lacertid lizard, psammodromus algirus.	in contrast to the view of a diffuse monoaminergic innervation of the telencephalon, studies on the monoaminergic innervation in certain mammalian isocortical regions have shown a high degree of regional and laminar specificity. the present study was designed to examine the distribution patterns of dopamine, noradrenaline and serotonin in a telencephalic structure, the anterior dorsal ventricular ridge, of the sand lizard psammodromus algirus (lacertidae) using specific antibodies against each m ...	1994	7987666
hosts on which nymphal ixodes ricinus most abundantly feed.	to identify hosts that may serve as european reservoirs for the agent of lyme disease, borrelia burgdorferi, we determined whether nymphal ixodes ricinus feed mainly on particular mice (apodemus flavicollis or a. agrarius), voles (clethrionomys glareolus) or on sand lizards (lacerta agilis) and whether the abundance of these hosts corresponds to the seasonal activity of the subadult stages of the vector tick. in all sites, the mice appeared most heavily infested by larvae; at least seven parasit ...	1991	1996733
[differences in macroglia of the spinal cord in various cold-blooded and warm-blooded animals].	certain macroglial differences of the spinal cord in poikilothermal (rana esculenta, lacerta agilis) and in homoiothermal (columba livia, felis domesticus, macaca rhesus) animals have been revealed. a greater amount of glial satellites, surrounding neurons, motor centers of the spinal cord and appearance of new variety of astrocytes and oligodendrocytes are observed in the homoiothermal animals. it is supposed that the phenomenon mentioned indirectly reflects the evolutionary process of a more d ...	1990	2275612
distribution of substance p, vasoactive intestinal polypeptide and serotonin immunoreactive structures in the central nervous system of the lizard, lacerta agilis.	the distribution of substance p (sp), vasoactive intestinal polypeptide (vip) and serotonin (5-ht) containing structures in the central nervous system of the lizard, lacerta agilis, were investigated with the aid of the peroxidase-antiperoxidase immunohistochemical method. sp and 5-ht nerve fibers are found almost all over the brain, whereas vip fibers are mainly observed in the limbic area, in the periventricular gray matter of the diencephalon and in the brain stem. the cells of origin are loc ...	1989	2477439
comparative demography of sympatric populations of lacerta vivipara and lacerta agilis.	a mark-recapture study was carried out in sympatric populations of lacerta agilis and lacerta vivipara in the netherlands from 1976 to 1982. in most years the age structure of both populations was pyramidal. for both species life expectation of females was higher and on average they did live longer. hence the sex ratio for adults deviated significantly from 1.0 in favour of females. maximum age for lacerta vivipara was 8 years (female) and for lacerta agilis 12 years (male). the density of both ...	1988	28312374
