An introduced species that has become naturalized.
Articulated corallines are branching, tree-like plants which are attached
to the substratum by crustose or calcified, root-like holdfasts.
The variability among living organisms from all terrestrial, marine, and
other aquatic ecosystems, and the ecological complexes of which they
are part: this includes diversity within species, between species and of
ecosystems.
All the plant and animal life of a particular region.
Taxonomic and quantitative attributes of a community of plants and
animals inhabiting a particular habitat, including species richness and
relative abundance structurally and functionally.
Coralline algae are red algae in the Family Corallinaceae of the order
Corallinales characterized by a thallus that is hard as a result of
calcareous deposits contained within the cell walls.
An alga that has a secondarily formed outer cellular covering over part
or all of an algal thallus. Usually relatively large and long-lived.
Crustose corallines are typically slow growing crusts of varying thickness
that can occur on rock, shells, or other algae.
Opportunistic algae with a short life cycle that are usually the first
settlers on a rocky shore.
General term for all of the animals found in a particular location.
General term for all of the plant life found in a particular location.
Leaf-like, broad and flat; having the texture or shape of a leaf.
Animals that feed by straining suspended matter and food particles
from water.
A collection of organisms of specific morphological, physiological,
and/or behavioral properties.
An herbivore that feeds on plants/algae by abrasion from the surface.
Native to the country not introduced.
The shore area between the high- and the low-tide levels.
Animals that do not have a backbone. Invertebrates either have an
exoskeleton (e.g. crabs) or no skeleton at all (worms).
A member of the order Laminariales, the more massive brown algae.
Capable of rapidly occupying newly available space.
A group of interdependent organisms inhabiting the same rocky shore
region and interacting with each other.
An animals that eats already dead or decaying animals.
Zone on the intertidal shore recognizable by its community.
General form of an alga that, unlike a plant, is not differentiated into
stems, roots, or leaves.
The relief features or surface configuration of an area.
Limpets that trap kelp fronds beneath their shells.
