BIODIVERSITY & hierarchy (folder)

  • Description : Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. (Wikipedia)

ecosystems, habitat & niche (FOLDER)

  • Description : An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. (Wikipedia)

population & migration (FOLDER)

  • Description : Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. (Wikipedia)

food webs & trophic levels (folder)

  • Description : A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1 the autotrophs, and 2 the heterotrophs The trophic level of an organism is the position it occupies in a food web.

coevolution & biogeography (folder)

  • Description : In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution. Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. (Wikipedia)

disturbance, restoration & resilience (folder)

  • Description : In ecology, a disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem. Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements. Environmental restoration is a term common in the citizens’ environmental movement. Resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. (Wikipedia)

paleontology (folder)

  • Description : Paleontology, also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. It includes the study of fossils to classify organisms and study interactions with each other and their environments. (Wikipedia)
