Biodiversity and Ecosystem Concepts
The variety and variability of all living organisms in an area.
What is Biodiversity?
The planned management, protection, and preservation of natural resources and ecosystems
What is Conservation?
A protected area of land, often publicly owned, managed for conservation.
What is Forest Preserver?
A fundamental mechanism of evolution where organisms better adapted to their environment tend to survive and produce more offspring
The evolutionary process by which populations evolve to become distinct species
What is Speciation?
The variety of roles, traits, and behaviors organisms perform in an ecosystem
What is functional biodiversity?
The process of assisting the recovery of ecosystems that have been degraded
A protected area of land or water managed by a state government, rather than the federal government
What is State Park?
A permanent, heritable change in the DNA sequence of an organism's genome
What is Mutation?
The complete disappearance of a species from Earth, occurring when the last individual member dies
What is Biological Extinction?
The direct and indirect benefits, or life-sustaining contributions that humans receive from nature
What is Ecosystem Services?
This is responsible travel to natural areas that conserves the environment.
It is an international agreement between governments, effective since 1975, designed to ensure that international trade in wild animals and plants does not threaten their survival.
What is Ecotourism?
What is CITES?
A high-quality natural area, such as prairies, forests, or wetlands, formally dedicated under state law to be protected in perpetuity from development
What is Illinois Nature Preserve?
Any environmental or biological factor that causes certain traits to have a higher or lower chance of surviving and reproducing within a population.
What is Selective Pressure
The complete disappearance of a species from Earth, occurring when the last individual of that species dies
What is Ecological Extinction?
A group of organisms that share similar characteristics, can naturally interbreed, and produce fertile offspring
What is Species?
The primary U.S. law designed to protect imperiled fish, wildlife, and plant species from extinction.
A large, government-protected area designated to conserve natural beauty, ecosystems, wildlife, and cultural, scientific, or historical sites.
What is Endangered Species Act?
What is National park?
A widespread, rapid decrease in the Earth's biodiversity, defined as the loss of approximately 75% or more of all species within a geologically short period
What is Mass Extinction?
the process or state of adjusting to new environments, conditions, or purposes
What is Adaptation?
The complete removal, destruction, or rooting out of something
What is Extirpation?
A large, naturally occurring community of flora and fauna occupying a major habitat
What is Biomes?
A federally owned, protected area of forestland and grassland managed for multiple uses.
A designated area of land or water in the United States, managed by the U.S. Fish and Wildlife Service (FWS), specifically dedicated to the conservation, management, and restoration of fish, wildlife, plants, and their habitats.
What is National Forest?
What is National Wildlife Refuge?
A proposed, unofficial geological epoch dating from the commencement of significant human impact on Earth's ecosystems, geology, and climate
What is Anthropocene?
The decreased susceptibility of a pest population to a pesticide that was previously effective at controlling it
What is Resistence?
The standard, natural rate of species extinction throughout Earth's history, occurring without human influence.
What is Background Extinction Rate?
