Being poikilothermic, their metabolism and growth can be regulated by temperature.
Poikilothermic animals' body temperature varies in accordance with the ambient temperature of their environment.
However, beyond the general positive relationships between temperature and poikilothermic metabolism (Jobling, 1997), the temperature response for fish is highly variable among species and populations, necessitating the measurement of temperature effects on a species-by-species basis.
Teleosts are poikilothermic animals and thus metabolically influenced by their environmental temperature and it has been shown that at temperatures below their optimum, the generation of specific antibody, although not abolished, is slowed down (Avtalion et al., 1973).
Lizards are apparently found everywhere in many of the warmer parts of the world because of their poikilothermic nature.
The wide neotropical distribution of the palms, their varied antropic uses and morphological variability permits the formation of trophic chains; from invertebrates to poikilothermic and homeothermic vertebrates, which provide the triatomines with readily available reservoirs as blood sources.
However, potential for infection between homothermic hosts and poikilothermic animals has been demonstrated.
However, unlike poikilothermic vertebrates, a great many traits in insects do not conform to theoretical scaling models, at least in terms of their physiological performance (Gabriel 1985a,b; Greenlee & Harrison 2004).
The book lungs constrain oxygen consumption in spiders, which exhibit resting metabolic rates about half those measured for other poikilothermic animals of equal mass (Anderson 1970; Greenstone & Bennett 1980).
