Ecological processes

Atmosphere

An atmosphere is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object.

See Soil-plant-atmosphere continuum and Atmosphere

Ecohydrology (from Greek οἶκος, oikos, "house(hold)"; ὕδωρ, hydōr, "water"; and -λογία, -logia) is an interdisciplinary scientific field studying the interactions between water and ecological systems. Soil-plant-atmosphere continuum and Ecohydrology are hydrology and soil physics.

See Soil-plant-atmosphere continuum and Ecohydrology

Evapotranspiration

Evapotranspiration (ET) refers to the combined processes which move water from the Earth's surface (open water and ice surfaces, bare soil and vegetation) into the atmosphere. Soil-plant-atmosphere continuum and Evapotranspiration are ecological processes, hydrology and water and the environment.

See Soil-plant-atmosphere continuum and Evapotranspiration

Humidity

Humidity is the concentration of water vapor present in the air.

See Soil-plant-atmosphere continuum and Humidity

Hydraulic redistribution

Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. Soil-plant-atmosphere continuum and Hydraulic redistribution are ecological processes, hydrology, plant physiology, soil physics and water and the environment.

John R. Philip

John Robert Philip AO FAA FRS (18 January 1927, Ballarat26 June 1999, Amsterdam) was an Australian soil physicist and hydrologist, internationally recognised for his contributions to the understanding of movement of water, energy and gases.

Leaf

A leaf (leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis. Soil-plant-atmosphere continuum and leaf are plant physiology.

See Soil-plant-atmosphere continuum and Leaf

Meteorology

Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting.

See Soil-plant-atmosphere continuum and Meteorology

Physiology

Physiology is the scientific study of functions and mechanisms in a living system.

See Soil-plant-atmosphere continuum and Physiology

Plant

Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic.

See Soil-plant-atmosphere continuum and Plant

Soil

Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms.

See Soil-plant-atmosphere continuum and Soil

Soil moisture

Soil moisture is the water content of the soil.

See Soil-plant-atmosphere continuum and Soil moisture

Soil physics

Soil physics is the study of soil's physical properties and processes.

See Soil-plant-atmosphere continuum and Soil physics

Stoma

In botany, a stoma (stomata, from Greek στόμα, "mouth"), also called a stomate (stomates), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere. Soil-plant-atmosphere continuum and stoma are plant physiology.

See Soil-plant-atmosphere continuum and Stoma

Transpiration

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Soil-plant-atmosphere continuum and Transpiration are hydrology and plant physiology.

See Soil-plant-atmosphere continuum and Transpiration

Transpiration stream

In plants, the transpiration stream is the uninterrupted stream of water and solutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast-interface of the substomatal cavity. Soil-plant-atmosphere continuum and transpiration stream are plant physiology and plant physiology stubs.
