Intro to Biodiversity
the number of diff. habitats available in a given area
What is Ecosystem diversity?
Goods and services provided by natural ecosystems that are beneficial to humans (often monetarily of life-sustaining)
What is Ecosystem Services?
higher ecosystem diversity and more available “niches” or roles
What is a Larger Island?
range where organisms survive, grow, and reproduce
What is Optimal Range?
A natural event that disrupts the structure and or function of an ecosystem
What is a Natural Disaster?
how different the genes are of individuals within a population (group of the same species)
What is Genetic diversity?
Nat. ecosystems regulate climate/air quality, reducing storm damage & healthcare costs
What is Regulating?
Closer to mainland means _________
What is Higher Species Richness?
range where the organism will die
Ex: thermal shock, suffocation, lack of food/water/oxygen
What is Zone of intolerance?
occurs with regular frequency (ex: dry-wet seasons)
What is Periodic?
the number of diff. species in an ecosystem and the balance or evenness of the pop. sizes of all species in the ecosystem
What is Species diversity?
Nat. ecosystems support processes we do ourselves, making them cheaper & easier(bees pollinate crops)
What is Supporting?
Islands closer to the “________” support more specie
What is the Mainland?
range where organisms survive, but experience some stress such as infertility, lack of growth, decreased activity, etc.
What is Zone of physiological stress?
no regular frequency (volcanoes, earthquakes, and asteroids)
What is Random?
a measure of how all of the individual organisms in an ecosystem are balanced between the different species
What is Evenness?
Money generate by recreation (parks, camping, tours) or scientific knowledge
What is Cultural?
Larger Islands Support More ______
What is Species?
Range of conditions such as temperature, salinity, pH, or sunlight that an organism can endure before injury or death results
What is Ecological Range of Tolerance?
occasional events with irregular frequency (ex: hurricanes, droughts, fires)
What is Episodic?
the ability of an ecosystem to return to its original conditions after a major disturbance (wind storm, fire, flood, clear-cutting, etc.)
What is Resilience?
Goods taken directly from ecosystems or made from nat. resources (wood, paper, food)
What is Provisioning?
Study of ecological relationships & community structure on islands
What is Island Biogeography?
Global warming warms the ocean, shifting temperature __________________
What is Outside the range of tolerance?
Major environmental disturbances result in widespread habitat__________
What is Change or Loss?
