Ka5 Metabloism And Adversed Conditions Flashcards
What is surviving adverse conditions by dormancy
Dormancy is a period of decreased metabolic rate, heart rate, breathing rate and body temperature
This is a part of some organisms lifestyle, may be predictive or consequential
What is predictive dormancy
Occurs before the start of adverse conditions
What is consequential dormancy
Occurs after the start of adverse conditions
Advantage as organism can remain active for longer
What is the different types of dormancy
Hibernation
Aestivation
Daily trooper
What is hibernation
A period of dormancy found in some mammal lifecycles to survive low temp during winter
What is daily trooper
A period of reduced activity each day found in some animals with higher metabolic rates
Wbag is aestivation
A period of dormancy found in some animal life cycles to survive high temperatures or a period of drought
Why are environments varied
Many environments very between tolerable limits for normal metabolic activity for an organism
Some animals are adapted to survive these adverse conditions
Other animals avoid these adverse conditions
How to avoid adveras conditions
Migration
The regular movements of members of the same species from one place to another over a long distance
Migrationary behviour is described as what
Inherited or innate
An animal is born with the instinct to do this or can be influenced or can learn from experiences
What animal groups migrate
All major animal groups
Eg birds, mammals, reptiles, amphibians, fish, insects
How does migration avoid metabolic adversity
By expending energy to relocate to a more suitable environment
What have science developed
Specialised techniques such as satellite tracking and leg rings to study long distance migration
What is a satokoge tracker
Glued to animals skin or implanted Under the skin
Signals are picked up by satilites so more precise information is gathered on migratory routes
What are leg rings
Metal leg rings containing the birds number and investigators contact details
When recaptured and information is reported the migratory behaviour can be mapped
