alga (pl. algae)
A chiefly aquatic plantlike organism that uses photosynthesis to produce its own food. Unlike plants, algae do not have true roots,
stems, or leaves.
The study of human origins, behavior, and physical, social, and cultural development.
A chain of islands.
An organism, such as a plant or alga, that manufactures its own food using light energy (photosynthesis) or chemical energy (chemosynthesis).
The multitude of interconnections, at levels from molecules to ecosystems, between living things and their environments. Scientists who study biocomplexity are often interested in how individual interactions combine to create large-scale dynamics and pattern.
When a species is of such low abundance that it can no longer support commercial harvesting.
All the species living together in an area.
The management and protection of the natural world.
A marine animal within the phylum Cnidaria that is composed of anatomical units called polyps and that typically forms a solid underskeleton of calcium carbonate (as in the "stony corals"), or an internal skeleton of calcareous spicules or complexes of protein and carbohydrates (as in the "soft corals"). Corals can be composed of single polyps, known as solitary corals, or multiple polyps, known as colonies. Colonial, stony corals that form large, rigid skeletons are sometimes known as reef-building corals to distinguish them from smaller stony corals and more flexible soft corals.
(1) An underwater geological structure, made largely of calcium carbonate, that is secreted by corals and other organisms (such as coralline algae, sponges, bryozoans, and mollusks) over long periods of time; (2) the biological community and ecosystem associated with such structures.
In economic terms, the creation of industries in an area which allow a higher standard of living for the human inhabitants.
The movement of organisms to new areas of habitat.
The geographic occurrence or range of an organism.
The relationships between organisms and their environments, and the study of those relationships.
A community of interacting organisms and their physical environment.
In danger of extinction in the foreseeable future.
All the external factors that affect an organism during its lifetime.
A group of fish that have come together to feed, migrate, or spawn.
All the activities involved to the exploitation of wild species or the harvest of farmed species. Fisheries frequently target many nonfish organisms, such as invertebrates (e.g., "shellfish"), algae, sea turtles, and marine mammals.
An inherited piece of information contained in a cell's DNA. The information from each gene is used to make a unique type of protein, which has a specific function for the cell.
The movement of genes among populations of a species. Depending on the organism, genes are carried by pollen, spores, seeds, sperm, eggs, and whole larval, juvenile, and adult organisms.
All the genes within a particular population; that is, total genetic variation.
The scientific study of heredity. Also, the genetic constitution of an individual, group, or class.
global positioning system (GPS)
A system of satellites, computers, and receivers that can determine the location (latitude and longitude) of a receiver on Earth.
The environment where an organism can and does live.
A type of seafloor or substrate that is primarily solid rock without substantial amounts of sediment. In many tropical seas, hardbottom is formed by coral reefs that, over time, create carbonate rock, called limestone pavement. In The Bahamas, however, most hardbottom substrates were originally formed through the consolidation of carbonate sand. Hardbottom habitats often have a thin layer of sand on top of rock. They support a variety of organisms including algae, soft corals, and hard corals.
An organism that eats plants or algae.
Relating to the whole of a system and the interconnectedness of its parts.
The scientific study of the physical conditions, boundaries, flow, and related characteristics of Earth's surface waters.
larva (pl. larvae)
The earliest free-living (e.g., hatched) life stage of an organism that undergoes metamorphosis.
The entire course of developmental change in an organism, often including fertilization of gametes, the growth of larval and juvenile stages, and reproduction by mature adults.
The full developmental program or history of an organism, including the specific schedule of life cycle stages, the types of allocations to growth and reproductive function, and the probability of surviving over time.
(1) Tropical and subtropical trees with salt-tolerant roots that grow along brackish shorelines; (2) the dense forests that these trees create along brackish waterways.
Relating to the sea.
marine protected area (MPA)
A portion of the marine environment set aside by law or other regulations to protect and preserve its flora, fauna, historical, or cultural features. Marine protected areas have different levels of protection and use, and can be called many different names, such as reserves, preserves, sanctuaries, refuges, parks, fishery management zones, national seashores, national monuments, critical habitats, and conservation areas.
A common term for a marine protected area. Marine reserves are often, but not always, designated as "no-take" (see below).
A theoretical system that represents scientific processes using a set of variables and the quantitative relationships between them.
An area of ocean that is closed to fishing or other extractive activities.
In The Bahamas, essentially any island other than the two most populated, New Providence and Grand Bahama.
The chemical process in which green plants (and blue-green algae) make carbohydrates from carbon dioxide and water using sunlight or light as an energy source. Most forms of photosynthesis release oxygen as a byproduct, the chief source of atmospheric oxygen.
The taking of organisms, such as fish, game, or plants, from a forbidden area.
A group of organisms of one species, occupying a defined area and usually isolated from similar groups of the same species.
Organisms that are hunted and eaten by predators.
The area naturally occupied by an individual, population, or species.
An area of land set aside for the use or protection of a species and its habitat.
A type of gorgonian (a soft coral) with a fanlike colony shape.
A simple multicellular marine invertebrate that grows attached to the bottom and feeds by pumping water through its body and filtering bacteria and other microscopic particles from the water.
An underwater flowering plant which, like land plants, has leaves, stems, and a root system.
The study of human social behavior.
In most cases, flexible corals without an extensive external skeleton.
A group of individuals, usually identifiable by a set of distinctive features, with a unique evolutionary history. Classically, the members of a species can interbreed only with each other to produce fertile offspring.
The haphazard, low-density spread of development.
A group of individuals within a species that, based on similarities in their production characteristics, are often managed as a unit in support of the same fisheries. In practice, stocks sometimes include individuals from multiple populations.
stony (hard) coral
A coral that posses a stony outer skeleton composed of calcium carbonate.
As frequently used in ecological science, to conduct a rigorous study of certain aspects of nature, such as the kind, abundance, or distribution of various organisms residing in some defined study area.
Populations or species likely to become endangered in the near future.
