Cytochemical study of spermiogenesis and mature spermatozoa in the lizard Tropidurus itambere (Reptilia, Squamata) [PDF]
Acta Histochemica, 2003 The present study was undertaken to detect essential components of spermatozoa by ultrastructural and cytochemical analyses of testis and epididymis of the lizard Tropidurus itambere at different points of its annual reproductive cycle. Cytochemical investigations of spermiogenesis have not been performed so far in Squamata and are scarce for lower ...

The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna [PDF]
Phyllomedusa: Journal of Herpetology, 2003 The demography of the lizard Tropidurus torquatus (Squamata, Tropiduridae) in a highly seasonal Neotropical savanna. The demography of a population of Tropidurus torquatus was studied from March 1996 until December 1998, in the Cerrado biome of central ...

Faunal Responses to Habitat Disturbance: Do the Principles Explaining Responses of Ant Communities Also Apply to Terrestrial Reptiles? [PDF]
Ecol EvolUnderstanding biotic responses to disturbance and their underlying mechanisms is critical to effective biodiversity conservation, but a predictive understanding of how faunal communities respond to disturbance remains elusive. In this paper, we review the applicability of a disturbance framework centred on habitat openness to understand terrestrial ...

Sperm ultrastructure and spermatogenesis in the lizard, Tropidurus itambere [PDF]
BIOCELL, 2003 Spermatogenesis, with emphasis on spermiogenesis, is described for the lizard, Tropidurus itambere, using light microscopy, phase contrast and epifluorescence, as well as scanning and transmission electron microscopy. Cellular differentiation involves events of chromatin condensation, nuclear elongation and the formation of structural complexes, such ...

Anais da Academia Brasileira de Ciências, 2015 Lizards' caudal autotomy is a complex and vastly employed antipredator mechanism, with thorough anatomic adaptations involved. Due to its diminished size and intricate structures, vertebral anatomy is hard to be clearly conveyed to students and ...

International Journal of Zoology, Volume 2012, Issue 1, 2012., 2012 We analyzed the locomotor behavior of a long‐tailed, forest floor, and leaf litter lizard, Colobodactylus taunayi, a species that retains the generalized Gymnophthalmidae Bauplan whilst presenting the discrete toe reduction associated with the Bachia‐like pattern of limb reduction.

Brazilian Journal of BiologyThe reproductive cycles of lizards, including Tropidurus species, have been widely studied. However, few studies describe in detail the ultrastructure and the epithelial changes in the epididymis.
