study for ecology test
age structure
the distribution of the proportion of population members in each age class
From openstax
carrying capacity
birth rate
the number of births within a population at a specific point in time
From openstax
carrying capacity
the maximum number of individuals of a population that can be supported by the limited resources of a habitat
From openstax
From openstax
climax community
the final stage of succession, where a stable community is formed by a characteristic assortment of plant and animal species
From openstax
competitive exclusion principle
no two species within a habitat can coexist indefinitely when they compete for the same resources at the same time and place
From openstax
death rate
the number of deaths within a population at a specific point in time
From openstax
demography
the statistical study of changes in populations over time
From openstax
density-dependent regulation
the regulation of population in which birth and death rates are dependent on population size
From openstax
density-independent regulation
the regulation of population in which the death rate is independent of the population size
From openstax
environmental disturbance
a change in the environment caused by natural disasters or human activities
From openstax
exponential growth
an accelerating growth pattern seen in populations where resources are not limiting
From openstax
foundation species
a species which often forms the major structural portion of the habitat
From openstax
host
an organism a parasite lives on
From openstax
intraspecific competition
the competition among members of the same species
From openstax
island biogeography
the study of life on island chains and how their geography interacts with the diversity of species found there
From openstax
J-shaped growth curve
the shape of an exponential growth curve
From openstax
K-selected species
a species suited to stable environments that produce a few, relatively large offspring and provide parental care
From openstax
keystone species
a species whose presence is key to maintaining biodiversity in an ecosystem and to upholding an ecological community’s structure
From openstax
life table
a table showing the life expectancy of a population member based on its age
From openstax
logistic growth
the leveling off of exponential growth due to limiting resources
From openstax
mark and recapture
a method used to determine population size in mobile organisms
From openstax
mimicry
an adaptation in which an organism looks like another organism that is dangerous, toxic, or distasteful to its predators
From openstax
mortality rate
the proportion of population surviving to the beginning of an age interval that dies during that age interval
From openstax
mutualism
a symbiotic relationship between two species where both species benefit
From openstax
