Mesotherms have two basic characteristics: [1] Elevation of body temperature via metabolic production of heat. Weak or absent metabolic control of a particular body temperature. The first trait distinguishes mesotherms from ectotherms, the second from endotherms. For instance, endotherms, when cold, will generally resort to shivering or ...
In contrast to ectotherms, endotherms rely largely, even predominantly, on heat from internal metabolic processes, and mesotherms use an intermediate strategy. As there are more than two categories of temperature control utilized by animals, the terms warm-blooded and cold-blooded have been deprecated as scientific terms.
For very precise positioning (e.g., in geodesy), these effects can be eliminated by differential GPS: the simultaneous use of two or more receivers at several survey points. In the 1990s when receivers were quite expensive, some methods of quasi-differential GPS were developed, using only one receiver but reoccupation of measuring points.
A eurytherm is an organism, often an endotherm, that can function at a wide range of ambient temperatures. [1] To be considered a eurytherm, all stages of an organism's life cycle must be considered, including juvenile and larval stages. [2] These wide ranges of tolerable temperatures are directly derived from the tolerance of a given ...
Animals can be further categorized as endotherms, which regulate their temperature internally, and ectotherms, which regulate temperature by the use of external heat sources. "Warm-bloodedness" is a complex and rather ambiguous term, because it includes some or all of: Homeothermy, i.e. maintaining a fairly constant body temperature.

Seismic noise. In geophysics, geology, civil engineering, and related disciplines, seismic noise is a generic name for a relatively persistent vibration of the ground, due to a multitude of causes, that is often a non-interpretable or unwanted component of signals recorded by seismometers. Physically, seismic noise arises primarily due to ...
Tape correction (surveying) In surveying, tape correction (s) refer (s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension.
