LIZARD - A Lightweight Stream Cipher for Power-constrained Devices
IACR Transactions on Symmetric Cryptology, 2017Time-memory-data (TMD) tradeoff attacks limit the security level of many classical stream ciphers (like E 0 , A5/1, Trivium, Grain) to 1 / 2 n , where n denotes the inner state length of the underlying keystream generator.

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).

Aim Evolutionary radiations into novel areas or niches require innovative adaptations. However, rapid subsequent changes in these novel conditions might demand rapid re-adaptations to secure population persistence and prevent extinction.

Grazing by goats on islands affects the populations of an endemic Mediterranean lizard
, 2013Grazing of goats on Mediterranean islets is a common practice. Its consequences on plant communities are well documented, although not on vertebrates. We aim to shed light on the effect of livestock farming on lizards by investigating five populations of

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
