The Evolution of Live-bearing in Lizards and Snakes
Most reptiles lay eggs, but many lizards and snakes are live-bearers. Taxonomic and embryological evidence indicates that egg-laying is ancestral (Weekes 1935; Matthews 1955; Amoroso 1960), so the common occurrence of genera containing both live-bearers and egg-layers shows that live-bearing has arisen from egg-laying several times (table 1). This paper considers the ecological conditions favor...
متن کاملTikiguania and the antiquity of squamate reptiles (lizards and snakes).
Tikiguania estesi is widely accepted to be the earliest member of Squamata, the reptile group that includes lizards and snakes. It is based on a lower jaw from the Late Triassic of India, described as a primitive lizard related to agamids and chamaeleons. However, Tikiguania is almost indistinguishable from living agamids; a combined phylogenetic analysis of morphological and molecular data pla...
متن کاملHow lizards turn into snakes: a phylogenetic analysis of body-form evolution in anguid lizards.
One of the most striking morphological transformations in vertebrate evolution is the transition from a lizardlike body form to an elongate, limbless (snakelike) body form. Despite its dramatic nature, this transition has occurred repeatedly among closely related species (especially in squamate reptiles), making it an excellent system for studying macroevolutionary transformations in body plan....
متن کاملShort Communication DYSTOCIA IN SHEEP AND GOATS: OUTCOME AND FERTILITY FOLLOWING SURGICAL AND NON-SURGICAL MANAGEMENT
Cesarean section is a life-saving surgical procedure usually undertaken in sheep and goats that fail to deliver vaginally (dystocia). Unfortunately, there are no recent review articles in literature that summarize the results of published case reports and clinical trials concerning indications, surgical approaches and procedures and outcomes following cesarean section in sheep and goats. Theref...
متن کاملEnergetic and physiological correlates of prey handling and ingestion in lizards and snakes.
In this review, we summarize the energetic and physiological correlates of prey handling and ingestion in lizards and snakes. There were marked differences in the magnitude of aerobic metabolism during prey handling and ingestion between these two groups, although they show a similar pattern of variation as a function of relative prey mass. For lizards, the magnitude of aerobic metabolism durin...
