Population
Comprised of all the individuals that belong to the same species that live in a specific area at a given time
Population
What is the term that describes the limit of how many individuals in a population the environment can sustain
Carrying capacity(K)
Relationship described when two interacting species benefit by increasing both species' chances of survival or reproduction, a win-win for both species
Mutualism
Organisms that have the ability to colonize new areas rapidly and grow well in full sunshine
Pioneer species
A tornado or forest fire would be an example of this factor that affects a population
Density-independent factor
What is N
represents the total number of individuals within a defined area at a given time
What is r?
Intrinsic growth rate, maximum potential for growth
Competing for a limiting resource can lead to this
resource partitioning
Ecological succession as a result of a forest fire, has not lost their soil but been disturbed
Secondary succession
What would be a limiting resource for terrestrial plant populations?
Water and nutrients such as nitrate and phosphate
a type of population distribution in which you would find schooling fish or a flock of birds
Clumped
J shaped curve
Exponential growth model
Elephants, primates, and whales would be an example of this type of species
K-selected species
Latitude, time, habitat, size, and distance from other communities will influence ________________ of a community
species richness
Rapid decline due to death
Die-off
A factor that influences an individual's probability of survival and reproduction in a manner that depends on the size of the population
Density dependent factor
Logistic growth model
S shaped curve, population is exponential at first then slows as approaches the K for its environment
Interaction described in which an animal consumers a producer, a gazelle
Herbivory
The first plant community that forms on bare rock often includes organisms such as
lichens and mosses
An area that contains a high proportion of the species found on Earth, such as the Madrean Pine-Oak Woodlands, Mexico where there is a Monarch Butterfly Biosphere Reserve
Biodiversity hotspot
One thousand two hundred and seventy deer are living on an island that is eight hundred and thirty square kilometers in size. What is the population density of the deer per square kilometer?
1.53 deer / square kilometer
Type of survivorship curve where species have very low rates of survival early in life
Type III curve
Typically exist in low numbers and a species that plays a far more important role in its community than its relative abundance might suggest
keystone species
the theory predicts that an island's size sets a maximum for how many species it can host, while its isolation and local speciation on the island will decide how many species it actually has, an useful tool for addressing questions in conservation biology, where a species' habitat may be reduced to distant patches
Island Biogeography
A great example of this would be the Galapagos Tortoise
Endemic species
