18 Questions
What is the main purpose of resource partitioning in an ecosystem?
To divide resources to avoid interspecific competition for limited resources
What is an example of habitat partitioning in anole lizard species found on the island of Puerto Rico?
Different species of lizards occupy different areas of habitat such as forest floors and trees
What is the characteristic of keystone species in an ecosystem?
They have a high impact on the ecosystem relative to their population
What is the adaptation of different species of bumblebees in the mountains of Colorado?
They have different lengths of proboscis to consume nectar from flowers of different species of plants
What do different species of anole lizard species found on the island of Puerto Rico have in common?
They have similar requirements for food
What is the result of resource partitioning in an ecosystem?
Different species coexist and are able to satisfy their needs from the limited resources present
What is a necessary condition for successful dispersal?
Withstanding long favourable conditions during travel
Which type of dispersal involves movement due to sudden events like floods or forest fires?
Forced Dispersal
What is the term for the means of transportation that help in dispersal of animals?
Carriers for Dispersal
Which type of dispersal is responsible for introducing non-native species to a region?
Anthropogenic Dispersal
What is the result of anthropogenic dispersal of European deers and rabbits in New Zealand?
Decrease in native natural vegetation
Which type of dispersal involves the movement of animals under their own power?
Active Dispersal
What is the term used to describe the dispersal of microorganisms by wind?
Anemochore dispersal
What type of carriers include air masses and air currents that transport micro-organisms?
Aeolian carriers
What is the primary mechanism by which Aeolian carriers transport microorganisms?
Through the gusty winds that lift them
Which type of dispersal is responsible for the transport of animals through oceanic water?
Hydrochore dispersal
What is a factor that influences the long-distance transport of animals through oceanic water?
Ability to withstand longer duration of immersion in oceanic water
What is an example of organisms that can be transported by Aeolian carriers through trapping devices?
Diptera, Hymenoptera, Homoptera and other arthropod insects
