Disturbance
succession
latitude gradient/area effects
island equilibrium
pathogens
100
Storm, fire, flood, drought, overgrazing or human activity.
What is a disturbance
100
begins where soil has yet to form
What is primary succession
100
evolutionary history and climate
What is two factors for latitude gradients
100
immigration and extinction
What effects the species diversity
100
can alter community structure
What are pathogens
200
describes most communities as constantly changing after being affected by disturbances
What is the non equilibrium model
200
makes the environment more favorable
What is facilitate
200
measure of potential water loss
What is potential evapotranspiration
200
mountain peaks separated by low lands
What is an island
200
intermediate species that transfer diseases
What are vectors
300
response to disturbance of the environment
What is ecological succession
300
has been cleared by a disturbance leaving soil intact
What is secondary succession
300
may increase in a community as more speciation occurs
What is species diversity
300
size and distance from the mainland
What affects immigration and extinction
300
vector
What are often parasites
400
states that moderate levels of disturbance can create conditions that foster greater species diversity.
What is the intermediate disturbance hypothesis
400
conditions are neither helped nor hindered by early species
What is tolerate conditions
400
offer a greater diversity of habitats and micro-habitats
What is a larger area
400
where immigration and extinction rates are plotted as functions of the number of species present on an island
What is an Island equilibrium model
400
diseases transferred from animal to human
What are zoonotic diseases
500
is usually severe and reduces species diversity
What is human disturbance
500
autotrophic and heterotrophic prokaryotes
What are the only life forms present In early primry succession
500
correlates with both measures of evapotranspiration
What is species richness of plants and animals
500
number of species already present on island
What affects immigration and extinction rates
500
community interactions
What helps track the spread of zoonotic diseases
