Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.
Marine diatoms are among the many planktonic organisms that paradoxically appear to flout the competitive exclusion principle.. In aquatic biology, the paradox of the plankton describes the situation in which a limited range of resources supports an unexpectedly wide range of plankton species, apparently flouting the competitive exclusion principle, which holds that when two species compete ...
Biology. Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus on either an increased quantity of offspring at the expense of reduced individual parental investment of r -strategists, or on a reduced quantity of offspring with a corresponding ...
Friday Harbor Laboratories (FHL), is a marine biology field station of the University of Washington, located in Friday Harbor, San Juan Island, Washington, United States. Friday Harbor Labs is known for its intensive summer classes offered to competitive graduate students from around the world in fields of marine biology and other marine sciences.
The organisms responsible for primary production are called primary producers or autotrophs. Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen.
The findings were published Tuesday in the biology journal Frontiers in Marine Science. This isn't the first case of "shark cannibalism," said Jon Dodd, executive director of the Atlantic Shark ...
History of marine biology. Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity. [1] The earliest studies of marine biology trace back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition. [2]
