Ecology

Geomorphic threshold

Biology; Ecology

The limit beyond which changes to a landform accelerate into a new state (e.g., a creeping slope suddenly falls over).

Merophytes

Biology; Ecology

Groups of cells that all originate from one cell. Merophytes build much of a plant, the leaves and stems in particular.

Nutrient cycling

Biology; Ecology

The cycling of nutrients through the environment and its inhabitants from soil to plants to animals and back to soil.

Diapsid

Biology; Ecology

A vertebrate whose skull has two pairs of side openings behind the eyes, e.g., lizards, crocodiles, snakes, dinosaurs.

Drawdown

Biology; Ecology

Dropping water levels in a dam or reservoir. Also: the overuse of resources faster than they can be replaced. See Oil.

Evapotranspiration

Biology; Ecology

The evaporation of water off leaf surfaces. A natural event, but can cause plants to lose too much water in dry times.

Matric force

Biology; Ecology

The attraction that holds water to soil particles. Contributes to soil cohesion and the formation of helpful colloids.
