The article focuses on leopard geckos in the highlands of Afghanistan that possess self-amputation ability, called autotomy, which allows them to shed their tail when attacked, and a study by biologist Kevin Jagnandan and others on how the gecko adapts to losing its tail by taking sprawled posture.

Behavioural Processes, 2000
Monogamy is relatively rarely reported in taxa other than birds. The reproductive system of many lizard species appears to involve multiple mating partners for both the male and the female. However, short-term monogamous relationships have been reported in some lizard species, either where the male defends a territory that is only occupied by a single ...

Evolution, 2002
Negative relationships between growth rate and survival have been demonstrated in many organisms, often reflecting risks associated with increased foraging rates. More puzzling, however, are recent reports that rapid growth early in life may lower survival rates much later in life, presumably because fast-growing animals allocate resources among ...

A Braitenberg Lizard: Continuous Phonotaxis with a Lizard Ear Model
2009The peripheral auditory system of a lizard is structured as a pressure difference receiver with strong broadband directional sensitivity. Previous work has demonstrated that this system can be implemented as a set of digital filters generated by considering the lumped-parameter model of the auditory system, and can be used successfully for step control

Electrophysiology of the lizard cochlea
Experimental Neurology, 1969The cochlear potentials of several species of lizard were measured, in particular Trachysaurus rugosus. Auditory responses were measured both at the round window and in scala tympani. The round window membrane was found to have considerable effect on the recorded potentials causing an attenuation and differentiation of summating potential (SP).

Publisher Summary This chapter focuses on the husbandry and health issues of common captive lizard species. The success of maintaining healthy lizards in captivity depends on the owner's ability to achieve two main goals: providing adequate nutrition and providing proper environment.

According to the theory of island biogeography, the number of species (richness) is determined by how an island's area and isolation govern rates of colonization, extinction and speciation. There is a long history of human introduction of anole lizards to Caribbean islands, hitching a ride on on crops such as pineapple and recently on ornamental plants

The Alligator Lizard and Granite Spiny Lizard
1990Anguid lizards are found on most continents and most have strongly reduced limbs. The alligator lizard of western North America is exceptional, in that it has relatively well-developed limbs and moves in a similar way to most other lizards. Since 1974, an extensive series of reports has been published on the structure and response activity of the ...

AbstractThe gecko ear was studied in 36 species belonging to 24 genera. This receptor has attained an advanced level of structure and performance in this group of lizards, but there are many variations among species. To a large extent these variations follow subfamily lines as represented in Kluge's system of classification.Brief consideration is given
