21 Terms

1

Wetlands

Areas that are inundated or saturated by surface or ground water, supporting vegetation adapted for life in saturated soil.

New cards
2

Obligate Wetland Plants

Plants such as cattail and bald cypress that require saturated soils to survive.

New cards
3

Facultative Wetland Plants

Plants that can grow in either wetland or upland conditions, such as red maple and cottonwood.

New cards
4

Salinity Zones

Different zones in estuaries based on salinity levels, including tidal freshwater, oligohaline, mesohaline, and polyhaline.

New cards
5

Anadromous Species

Fish species, like the American shad, that migrate from the ocean into freshwater to spawn.

New cards
6

Universal Solvent

Refers to water's ability to dissolve many compounds, mainly ions.

New cards
7

Chesapeake Bay

An estuarine system where various fish species including the Blue Crab and American Shad are monitored for population and health.

New cards
8

Tidal Freshwater

A salinity zone in estuaries with very low salinity (0.5 ppt) that is influenced by tidal actions.

New cards
9

Carbonic Acid

A weak acid formed when carbon dioxide dissolves in water; involved in the buffering capacity of aquatic systems.

New cards
10

Alkalinity

The capacity of water to resist acidification, influenced by bicarbonate and carbonate levels.

New cards
11

Ecosystem Stressors

Factors such as overharvesting and pollution that negatively affect aquatic ecosystems.

New cards
12

American Oyster

A bivalve mollusk and iconic species in estuaries known for its ecological and economic importance.

New cards
13

Mangroves

Coastal trees that thrive in saline water, forming a vital habitat along tropical coastlines.

New cards
14

Estuary

A partially enclosed coastal body of water where freshwater from rivers meets and mixes with saltwater from the ocean.

New cards
15

Oligohaline

A salinity zone in estuaries with salinity levels from 0.5 to 6 parts per thousand.

New cards
16

Facultative Upland Plants

Plants that are usually found in non-wetland areas but may occasionally be found in wetlands.

New cards
17

Spat

A young oyster that settles to the bottom and attaches to hard surfaces.

New cards
18

Sphagnum Moss

A type of moss that dominates in bogs and contributes to the accumulation of organic matter.

New cards
19

Shellfish

Aquatic animals with shells, such as oysters and crabs, that are vital to both ecological and commercial systems.

New cards
20

Photosynthesis

The process by which plants use sunlight to produce food, affecting the water's pH and carbonate system.

New cards
21

Respiration in Aquatic Systems

The metabolic process where oxygen is consumed and carbon dioxide is produced by aquatic organisms.
