Effects of tail loss on the movement patterns of the lizard, Psammodromus algirus
TLDR
The movement patterns of spontaneously moving Psammodromus algirus lizards and their escape performance running at high speed were compared before and after tail loss, and alterations for the ecology of this species are discussed. Expand
The cost of producing a sexual signal: testosterone increases the susceptibility of male lizards to ectoparasitic infestation
Alfredo Salvador, Jose P. Veiga," Jose Martin,*'' Pilar Lopez,* Maria Abelenda, and Marisa Puerta Departamento de Ecologia Evolutiva, Museo Nacional de Ciencias Naturales, C.S.I.C., J. GutierrezExpand
When to come out from a refuge: risk- sensitive and state-dependent decisions in an alpine lizard
TLDR
It is concluded that optimization of refuge-use strategies might help lizards cope with changes in predation risk without incurring excessive physiological costs. Expand
Sources of individual shy–bold variations in antipredator behaviour of male Iberian rock lizards
TLDR
It is suggested that the position of an individual in the shy–bold continua might reflect its optimal antipredator behaviour, which would be a function of its health, general quality and ability to evade predators. Expand
An experimental test of the costs of antipredatory refuge use in the wall lizard, Podarcis muralis
TLDR
It is suggested that an increase in the time spent in refuges at unfavourable temperatures during the experiment led to a loss of time available for foraging and a diminution of the efficiency of physiological functions, which resulted in loss of mass. Expand
Multiple color signals may reveal multiple messages in male Schreiber’s green lizards, Lacerta schreiberi
TLDR
Results showed that interindividual variation in the characteristics of coloration of males can be related to variation in morphology, health state, dominance status, and pairing status, but that different relationships were found for each color signal. Expand
Fleeing to unsafe refuges: effects of conspicuousness and refuge safety on the escape decisions of the lizard Psammodromus algirus
TLDR
A large number of studies have suggested that the optimal distance at which an animal starts to flee (approach distance) increases with distance to the refuge, but the extent of reliance on that distance is still poorly constrained. Expand
Risk level of chemical cues determines retention of recognition of new predators in Iberian green frog tadpoles
TLDR
Results indicate that tadpoles are able to modify their antipredatory behavior according to the degree of risk implied by the experimental cues, and their previous experience of chemical cues of the predator. Expand
Interpopulational differences in chemical composition and chemosensory recognition of femoral gland secretions of male lizards Podarcis hispanica: implications for sexual isolation in a species
TLDR
Differential tongue-flick rates to scents from femoral secretions indicated that males were able to detect and discriminate between males of different types based on chemical cues alone, in contrast, females detected but did not seem able to discriminate between scents of the two types of males. Expand
Influence of habitat structure on the escape tactics of the lizard Psammodromus algirus
We examined the escape responses of a population of lizards (Psammodromus algirus) in relation to reasonal variation in the habitat caused by the presence or absence of leaves in deciduous shrubs u...
