Kelp Forest Glossary




Abiotic Environment

The physical surroundings of an organism
Affirm
Establish or strengthen as with new evidence or facts
Air Bladders
Anything inflated or hollow; inflated hollow structure called a vesicle in an algae, often filled with air, to aid floating
Algae
Any of a large group of simple plants that contain chlorophyll; are not divisible into roots, stems and leaves; do not produce seeds; and include the seaweeds and related freshwater and land plants
Annual
A plant that completes its entire life cycle within the space of a year
Aquatic
Living or growing in or on the water
Biodiversity
An expression of the number of different species occurring in a given area
Blade
The broad, flattened, leaf-like part of a seaweed thallus
Canopy
The "roof" of the forest formed by the tops of the tallest kelp
Chlorophyll
Green-colored pigments that plants use to help make their own food
Climate
The general or typical atmospheric conditions for a place and/or period of time; conditions include rainfall, temperature, thunderstorms, lightening, freezes, etc.
Consumptive
The use of a resource that reduces the supply, such as harvesting kelp
Crustaceans
A group of mainly aquatic animals including crabs, shrimps, and barnacles, with hard outer skeletons or shells and paired, jointed, limbs
Diversity
Number of species in a particular community or habitat
Dynamic equilibrium
The condition of balance between varying, shifting and opposing forces which is characteristic of living processes
Ecological
Relating to the interrelationships of organisms and their environment
Ecosystem
A community of organisms, interacting with each other plus the environment, in which they live and react
Estuarine
A bay, influenced by the ocean tides, which has resulted in a mixture of salt water and fresh water
Eukaryotic
Referring to a cell with a nucleus and other internal structure
External activities
Activities outside a place, such as a national park, that may affect the biotic and abiotic elements within the place
Extractive
Involved in removing or taking something out; the extractive kelp industry is one in which workers harvest kelp for processing into a variety of products
Filter-feeding
Animals that take water into their bodies and filter out water-borne debris and dissolved organic matter
Food web
The connections among everything organisms in a location are eaten by and eat
Forage
To wander or rove in search of food
Frond
The "leaf" of the kelp plant; fronds also release the plant's spores or "seeds"
Habitat
The natural home of a plant or animal
Holdfast
A part of a kelp that clings to a flat surface
Intertidal zone
The region in an ocean that lies between the highest high tide level and the lowest low tide level; biota living in the intertidal zone are alternately covered and then uncovered by water
Invertebrate
An animal with no backbone or spinal column
Kelp
Any one of brown algae or seaweed, often growing in oceanic "forests"
Kelp forests
Underwater forests of tall, brown algae that grow in cool coastal waters
Lobbyist
Someone who tries to persuade legislators to vote for bills that the lobbyists favor; lobbyists are usually paid by the group they represent
Macrocystis
A genus name meaning "large bladder"
Marine
Living in the sea and not in fresh water
Marine snow
Organic materials floating in the water column near the surface that clump together and eventually sink to the bottom; these clumps of "snow" continuously drift down from the surface waters, delivering nutrients to the deep-water organisms
Mean low water
The average level of low water at a place over a 19-year period
Meltwater
Water resulting from the melting of snow or glacial ice; glacial meltwater often forms streams and carries rock material beyond active glaciers
Morphologic
Describing the form and structure of an organism or any of its parts
Motile
Ability to move at will
Mud flats
A wide area of fine sediment exposed at low tide, on the seaward side of a coast in sheltered waters
Multicellular
Organisms that are made up of more than one cell (compare with unicellular)
Nutrients
Substances which are required to support living plants and organisms
Op-ed
An op-ed is a piece of writing expressing an opinion. Such items are often found in a full newspaper page, containing articles by columnists, letters to the editor, and other information, rather than news or facts.
Organic Act (1916)
An act that, among other things, established the National Park Service
Perennial
A plant that lives for more than 2 growing seasons
Phenomenon
An unusual or remarkable fact or event
Photosynthesis
The process by which green plants, algae and some bacteria absorb light energy and use it to synthesize their food (organic compounds)
Planktonic
Suspended plants and animals that are incapable of locomotion and are carried by the currents
Plant
Living organism that makes its own food from inorganic substances and has neither the power of movement nor special organs, sensation or digestion
Pneumatocysts (pneu=air/cyst=ball)
Rounded organs like balloons that hold the kelp up to get more sunlight
Protist
Organisms that are not considered true animals, plants or fungi; includes algae of all kinds
Rainforest
A closed forest in areas of high precipitation with a large diversity of species forming a deep, densely interlacing canopy in which vines and ferns are often present
Reintroduce
To return members of a species to their historical range; this strategy is sometimes used when a species has become locally extinct or if its population is threatened
Sediments
Fine particles of rock, dirt or sand that have settled to the bottom of a body of water
Silt
Fine particles of soil floating in rivers, ponds, or lakes and settling to the bottom as sediment
Stem
Slender or elongated structure that supports a plant or fungus or a plant part or plant organ
Stipe
The stem of a kelp plant; it is hollow and is full of air which helps to keep it upright in the water column; it is also flexible, which allows it to bend in the water's strong currents
Strata
Classification of forest based on height, age and species composition
Subtidal
The portion of a tidal-flat environment that lies below the level of mean low water for spring tides; normally, it is covered by water at all stages of the tide
Subtidal zone
Region in the ocean that lies below the range of tidal exposure; always covered by water
Successional
Relating to the gradual replacement of one plant community by another through natural processes over time
Terrestrial
Of or relating to or inhabiting the land, as opposed to the sea or air
Thallus
A plantlike organism not divided into leaves, stem, and root; mushrooms and lichen are examples of thalli
Tide
The regular rise and fall of the sea level under the gravitational pull of the moon; high tide, when the water reaches its highest level, occurs twice a day; low tide, when the water reaches its lowest level, occurs twice a day
Tidewater Glacier
Glaciers that flow into the sea
Unicellular
One-celled organisms
Urchin barrens
Large congregations of sea urchins that have eaten all the kelp
Vascular tissues
Tissues found in the bodies of vascular plants that transport water, nutrients, and carbohydrates
Venn diagram
A useful way of comparing sets; a typical Venn diagram uses overlapping circles to represent groups of items or ideas that share common properties
