The Regenerative Capacity of the Tail in Embryonic and Post-natal Lizards (lacerta Vivipara Jacquin).
M A N Y studies have been made on autotomy and regeneration of the tail in lizards; for example those by Woodland (1920) and Hughes & New (1959) on geckos, by Slotopolsky (1922) on Lacerta, by Barber (1944) and Kamrin & Singer (1955) on Anolis, and by Simpson (1964) on Lygosoma. This work is concerned with the adult, and, so far as we are aware, no comparable studies on young and embryonic liza...
متن کاملMetabolic adaptations of overwintering European common lizards (Lacerta vivipara).
The European common lizard Lacerta vivipara, a reptile of cold-temperate climates, provides us an interesting model of low-temperature adaptation. Indeed its unique cold-hardiness strategy, which employs both freeze tolerance and freeze avoidance, may be seen as the primary reason for its large distribution, which extends from Spain to beyond the Arctic circle. To study the metabolism supportin...
متن کاملIntraspecific phylogeography of Lacerta vivipara and the evolution of viviparity.
The lacertid lizard Lacerta vivipara is one of the few squamate species with two reproductive modes. We present the intraspecific phylogeny obtained from neighbor-joining and maximum-parsimony analyses of the mtDNA cytochrome b sequences for 15 individuals from Slovenian oviparous populations, 34 individuals from western oviparous populations of southern France and northern Spain, 92 specimens ...
متن کاملCharacterization and androgenic regulation of major mRNAs coding for epididymal proteins in a lizard (Lacerta vivipara).
During the reproductive period (spring) under the control of testosterone the epididymis of the viviparous lizard secretes a group of major proteins with an approximate Mr of 19,000 named L protein(s). These proteins are recognized by a specific immunoserum and bind to the heads of spermatozoa. During spring, translation in reticulocyte lysate of RNA from secreting epididymis (stage 6) produced...
متن کاملComparison of the cold hardiness capacities of the oviparous and viviparous forms of Lacerta vivipara.
The lizard Lacerta vivipara has allopatric oviparous and viviparous populations. The cold hardiness strategy of L. vivipara has previously been studied in viviparous populations, but never in oviparous ones. The present study reveals that both the oviparous and viviparous individuals of this species are able to survive in a supercooled state at -3 degrees C for at least one week when kept on dr...
