meso-, mes-, mesi-

(Greek: middle, intermediate; close to a center line; between)

mesohalobous
A reference to planktonic organisms living in brackish water with a salinity (saltiness) between 5 and 20 parts per thousand.
Mesohippus
An extinct mammal of the horse family, but not larger than a sheep, and having three toes on each foot.
mesohydrophyte
A plant that thrives under damper conditions than a true mesophyte does.
mesohydrophytic
A reference to any plant whose tolerance to moisture is intermediate between that of a mesophyte and a hydrophyte.

These terrestrial plants are adapted to neither a particularly dry nor a particularly wet environment.

An example of a mesophytic habitat would be a rural temperate meadow, which might contain Goldenrod, Clover, Oxeye Daisy, and Rosa multiflora.

mesohylile
A reference to moist forest habitats (living areas).
mesolite
A zeolitic mineral, grayish white or yellowish, occuring in delicate groups of crystals, also fibrous massive.

It is a hydrous silicate of alumina, lime, and soda.

Mesolithic
The Middle Stone Age, an archaeological period about 10,000 to 4,000 years B.C.
mesolithion
Organisms that live in rock cavities.
mesology
A former term for ecology or the study of the interrelationships between organisms and their environents and each other.
mesomerism
The existence of organic chemical structures that cannot be accurately represented by a single structural formula, the actual formula lying in the middle between several possible representations that differ only in the position of electrons.
mesometeorological
A reference to the study of atmospheric phenomena of relatively small size; such as, thunderstorms or tornadoes, and of the detailed structure of larger disturbances.
mesometeorology
A part of the science of meteorology concerned with the study of atmospheric phenomena on a scale larger than that of micrometeorology, but smaller than the cyclonic scale.
mesomorph
1. A husky muscular body, or someone who has such a body.
2. An individual with a robust, muscular body build caused by the predominance of structures developed from the embryonic mesodermal layer.
3. An individual having a type of body build in which tissues derived from the mesoderm predominate.

There is a relative preponderance of muscle, bone, and connective tissue, usually with a heavy, hard physique; a somatotype (body type) classified between ectomorph (physiological type that is tall with long lean limbs) and endomorph (a stocky build with a prominent abdomen).

mesomorphic
1. A reference to a muscular or sturdy body build characterized by the relative prominence of structures developed from the embryonic mesoderm (contrasted with ectomorphic, endomorphic).
2. In chemistry, pertaining to or existing in an intermediate state, as a liquid crystal in the nematic or smectic state.
mesomorphism
1. A reference to one of the three classic somatotypes, or body types.

Typically speaking mesomorphism refers to people who have strength and an athletic build. They can develop and build [muscle] mass without much difficulty and can usually eat without too much fear of gaining weight.

2. Having physical form, structure, or size which is average, normal, or intermediate between extremes.
