512 Reproductive Biology and Phylogeny of Snakes from ecological and ultimate
(evolutionary) perspectives, but also from the simply mechanistic standpoint of the dynamics …

Deliberate tail loss was recorded for the first time in three large whip snakes (Dolichophis
caspius) and one dice snake (Natrix tessellata). Observations were made in different years …

The ecology of the genus Thamnodynastes has received little study, and problems with its
taxonomy have generated imprecise and incorrect data. We analyzed the reproductive …

Two hypotheses have been proposed to explain the differences among species within
present-day communities: the competition-predation hypothesis (CPH) and the deep history …

Few extensive studies have addressed the ecology of South American colubrids. Spilotes
pullatus is a large and conspicuous colubrid snake with a broad distribution in South …

The present study is a taxonomic revision of the genus Drymoluber Amaral, 1930, using
meristic and morphometric characters, aspects of external hemipenial morphology and body …

This study aimed to describe the reproductive biology of populations of Thamnodynastes
hypoconia in subtemperate wetlands based on macroscopic analyses of their gonads. We …

Studying life history (LH) allows a broader understanding of organisms and populations'
responses to their environments. Snakes display an immense diversity in terms of …

Sexual dimorphism is a common phenomenon among snakes, with female snakes being
larger than male snakes as a recurrent pattern. However, species that show male-male …

Pseudoautotomy (no spontaneous tail breakage without regeneration) occurs in the snakes
