Rolland explained that animals that can regulate their body temperatures, known as endotherms, might be better able to survive in these places because they can keep their embryos warm, take care of their offspring and they can migrate or hibernate.
ulcerans known to cause BU in humans and other mycolactone-producing mycobacteria strains that contain IS2404 but have fewer copy numbers of IS2606 and are not known to cause disease in endotherms.
The melting endotherms in the case of the 3 X 3 simultaneous samples were wider than the 3 X 1 samples indicating a wider distribution of the crystalline sizes in the case of the simultaneously stretched samples.
Energetic demands are roughly an order of magnitude greater in endotherms relative to ectotherms of the same size (e.
Marine reptiles have attracted far less attention in this respect, but we expect ectotherms to diverge dramatically from endotherms in several dive parameters, especially because ectothermy reduces oxygen demand.
By measuring the exotherms and endotherms, it is possible to determine all the chemical and physical state changes that occurred in the sample.
The broad endotherms observed in the range 150-289[degrees]C, (onset at 175.
But biologists have found exceptions called regional endotherms, which can maintain warmth in certain tissues.
This makes sense, because an increased body size is adaptive for endotherms in that it exposes a lower surface area relative to its volume, thus reducing heat loss.
Warm blooded endotherms are capable of maintaining a steady balance in body temperature through their own metabolism.
Allen's rule states that endotherms inhabiting colder climates tend to have shorter appendages than those of the same species in warmer areas.
