Sex ratio bias, male aggression, and population collapse in lizards
The adult sex ratio (ASR) is a key parameter of the demography of human and other animal
populations, yet the causes of variation in ASR, how individuals respond to this variation …

Evolutionary aspects of tail shedding in lizards and their relatives
EN Arnold - Journal of Natural History, 1984 - Taylor & Francis
The ability to shed (autotomize) all or part of the tail, usually in response to predator attack,
and often to subsequently regenerate it is widespread in lizards and amphisbaenians and …

The seasonal timing of oviposition in sand lizards (Lacerta agilis): why early clutches are better
We studied a population of sand lizards (Lacerta agilis) near the northern edge of the
species' range in coastal Sweden. We captured, marked, released and recaptured 98 adult …

Growth plasticity and thermal opportunity in Sceloporus lizards
We studied the relationship between daily active time and growth rate in hatchling
sagebrush lizards (Sceloporus graciosus), a mainly montane species, and western fence …

Why don't small snakes bask? Juvenile broad‐headed snakes trade thermal benefits for safety
JK Webb, MJ Whiting - Oikos, 2005 - Wiley Online Library
Previous studies have suggested that most small Australian elapid snakes are nocturnal and
rarely bask in the open because of the risk of predation by diurnal predatory birds. Because …

An experimental test of the costs of antipredatory refuge use in the wall lizard, Podarcis muralis
Prey often respond to predator presence by increasing their use of refuges. However, refuge
use may have some costs such as lost opportunities for foraging, and also physiological …

The effects of tail loss on survival, growth, reproduction, and sex ratio of offspring in the lizard Uta stansburiana in the field
SF Fox, JK McCoy - Oecologia, 2000 - Springer
Tail autotomy is a defense against predators used by many lizard species but is associated
with various costs, most of which have been measured only in the laboratory. We conducted …

The timing of reproduction in the lizard Lacerata vivipara: differences between individual females
D Bauwens, RF Verheyen - Journal of Herpetology, 1985 - JSTOR
During a field study examining the live-bearing lizard Lacerta vivipara, we estimated the
timing of mating, ovulation and parturition in individual females. Reproduction was …

Three questions about the eco‐physiology of overwintering underground
In cold environments ectotherms can be dormant underground for long periods. In 1941
Cowles proposed an ecological trade‐off involving the depth at which ectotherms …

When to come out from a refuge: balancing predation risk and foraging opportunities in an alpine lizard
Prey often respond to predator presence by increasing their use of refuges, but because this
strategy may be costly, the decision regarding when to come out from a refuge should be …
