Size-fecundity relationships, growth trajectories, and the temperature-size rule for ectotherms
However, with respect to this rule, it is clear that its author devised it for endotherms, and that perhaps its extension to ectotherms
produces these paradoxes.
In our study, we found that glycogen content, crude protein and ash in whole body were affected by temperature suggesting that temperature influences the physiological characteristics of ectotherms
(Gillooly et al.
Ranges of optimal temperatures for various performance measures are also generally broader for smaller, juvenile ectotherms
(Freitas et al.
2000; Meiri and Dayan, 2003), but also to certain groups of ectotherms
Lags have also been found in the bones of reptiles and amphibians and have until now been assumed to be limited to ectotherms
- cold-blooded animals - that are more subject to the whims of harsh environments.
These results were also consistent with their dietary and behavioral habits, wood turtles being semi-aquatic, omnivorous ectotherms
that live in water and use gills to get oxygen; fleshy filaments that are filled with tiny blood vessels; fanlike structures used for steering, balancing, and moving; those on the top and bottom; hard, thin, overlapping plates that cover the skin).
Because butterflies are ectotherms
, the length of their life stages can be slowed or sped up somewhat by controlling the temperature of their environment.
After ~11 days of incubation (some by the male), four or five hatchlings emerge that will develop from tiny (1-2 g) naked ectotherms
into fully feathered, warm-blooded, adult-sized (20-25 g) flying machines within just 2 weeks.
These animals are ectotherms
and sunbathe to regulate their body temperature.
generally exhibit preferred body temperatures ([T.
Though limited by the small number of individuals included, our study highlights these important aspects of thermal biology and draws attention to the need for future studies of over-wintering thermoregulation in ectotherms
The other chapters discuss defining stress in aquatic animals; the nature of anesthesia, sedation, and analgesia; the features of anesthetic agents; anesthesia and legislation; factors affecting the response of aquatic ectotherms
to anesthesia; inhalation anesthesia; inhalation anesthesia using gases; parenteral and oral anesthesia; non-chemical methods; anesthesia of aquatic invertebrates; anesthesia of amphibians and reptiles; and transportation and anesthesia.
It is believed that ectotherms
are the largest reservoir for subspecies III.
