Ovarian follicular cycle of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata: Tropiduridae) in a semiarid region of Brazil [PDF]
The reproductive cycle of Squamata reptiles is often associated with environmental conditions, such as rainfall. In this respect, seasonal variations may affect the morphology of the ovarian follicles, which are associated with vitellogenesis.

The effects of seasonality on the foraging behavior of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata: Tropiduridae) living in sympatry in the Caatinga of northeastern Brazil [PDF]
In this study, we performed field observations of 38 and 84 specimens of the lizards Tropidurus hispidus (Spix, 1825) and Tropidurus semitaeniatus (Spix, 1825), respectively, inhabiting a Caatinga in the state of Rio Grande do Norte, northeastern Brazil,

Anti-predator behaviour changes following an aggressive encounter in the lizard Tropidurus hispidus [PDF]
Avoiding predators may conflict with territorial defence because a hiding territorial resident is unable to monitor its territory or defend it from conspecific intrusions. With persistent intruders, the presence of an intruder in the near past can indicate an increased probability of future intrusions.

Trophic ecology and foraging behavior of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata, Tropiduridae) in a caatinga area of northeastern Brazil [PDF]
This study aimed to analyze the seasonal variation in diet composition and foraging behavior of Tropidurus hispidus (Spix, 1825) and T. semitaeniatus (Spix, 1825), as well as measurement of the foraging intensity (number of moves, time spent stationary, distance traveled and number of attacks on prey items) in a caatinga patch on the state of Rio ...

First Record of leucism in Tropidurus hispidus (Spix, 1825) (Squamata: Tropiduridae) in north Brazil, Eastern Amazon [PDF]
In vertebrates leucism does not occur frequently in nature but has been recorded in amphibians and reptiles. Herein we report the first record of leucism in Tropidurus hispidus from north Brazil, Eastern Amazon.
