Ecology
Evergreens
Biology; Ecology
Trees that keep their foliage throughout the year. Needle-shaped leaves retain moisture with less loss to transpiration. Compare Deciduous.
Osmoregulation
Biology; Ecology
The ability to control mineral and salt concentration in the blood. Some fish do this to help them move among waters that vary in salinity.
Endoplasmic reticulum
Biology; Ecology
Network of tubes and sacs involved with making protein (with ribosomes) and steroids and with storing calcium and glycogen (stored sugar).
Endocrine disruptor
Biology; Ecology
A pesticide chemical that interferes with hormones. It is suspected to cause vaginal cancer, immune system deficiencies, and birth defects.
Spring tide
Biology; Ecology
The high and low tide preceding a neap tide. Combined tidal pulls from Sun and Moon make the tide rise higher and fall lower than normal.
Resuspension
Biology; Ecology
Dispersion of particles back into water, as when wave action or dredging stir up sediments that had fallen out of suspension and settled.
Zooplankton
Biology; Ecology
Plankton that do not produce their own food, as phytoplankton do. In size they fall between phytoplankton and larger organisms like fish.
