Paleontologists are now learning what physiologists have known for years--that some modern ectotherms can grow rapidly and have extremely active lifestyles.
In conclusion, Wroe says the parable of a continent, `wherein diminutive mammals trembled under the footfalls of a menagerie of gigantic ectotherms, appears to be a castle in the air'.
Seasonal cues such as photoperiod and temperature, acting through the neuroendocrine system, have been proposed as responsible for multiple changes in immune function indicators in ectotherms (44).
Despite the shortness of the egg period, egg temperature plays a crucial role in egg traits of ectotherms, such as egg development (Du et al.
Like today's sea-faring tuna and great white sharks, dinos share some traits with both ectotherms (what people mean when they say "cold-blooded") and endotherms ("warm-blooded").
Although most ectotherms have only limited ability to thermoregulate via physiological adjustment, many use behavioral adjustments to regulate body temperatures at remarkably narrow species-specific levels (Huey 1991, Madeira et al.
Populations of John's Snapper farthest from the equator had the largest body sizes, in line with James's rule, and the fastest growth rates, contrary to the temperature-size rule for ectotherms.
Hence, oxygen could be the key resource limiting growth in aquatic ectotherms.
This can occur only in ectotherms, animals that do not maintain a constant body temperature.
This needs to be taken into account for scientific studies of other cold-blooded animals, or ectotherms, such as reptiles and amphibians," he said.
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.
