Reproduction in female reindeer.
Reindeer are either wild or kept under very extensive farming systems. They are seasonal breeders, with mating coinciding with the decreasing photoperiod in the autumn, and with calving in the spring. Little is known regarding the factors that influence reproduction in reindeer or of their reproductive physiology. Studies carried out to date have mainly focused on issues related to the populati...
متن کاملPanting in reindeer (Rangifer tarandus).
Two winter-insulated Norwegian reindeer (Rangifer tarandus tarandus) were exposed to air temperatures of 10, 20, 30, and 38 degrees C while standing at rest in a climatic chamber. The direction of airflow through nose and mouth, and the total and the nasal minute volumes, respectively, were determined during both closed- and open-mouth panting. The animals alternated between closed- and open-mo...
متن کاملRecent advances in thermoregulation.
Thermoregulation is the maintenance of a relatively constant core body temperature. Humans normally maintain a body temperature at 37°C, and maintenance of this relatively high temperature is critical to human survival. This concept is so important that control of thermoregulation is often the principal example cited when teaching physiological homeostasis. A basic understanding of the processe...
متن کاملThermoregulation in multiple sclerosis.
Multiple sclerosis (MS) is a progressive neurological disorder that disrupts axonal myelin in the central nervous system. Demyelination produces alterations in saltatory conduction, slowed conduction velocity, and a predisposition to conduction block. An estimated 60-80% of MS patients experience temporary worsening of clinical signs and neurological symptoms with heat exposure. Additionally, M...
متن کاملThermoregulation in African chameleons
Field active and laboratory preferred body temperatures and critical thermal limits were measured in six species of Kenyan chameleons: Chamaeleo bitaeniatus, C. dilepis, C. ellioti, C. hohnelii, C. jacksonii, and C. schubotzi. Given the opportunity, all six species are very competent heliothermic thermoregulators. Individuals typically spend the night low in shrubby vegetation with body tempera...
