Unit 2- Feild Work Techniques Flashcards
Define a Hazard
A hazard is something that can cause harm
Define a risk
A rush is the likely hood of being harmed from exposure to a hazard
List 4 key hazards associated with field work
Adverse weather
Difficult terrain
Isolation
Contact with harmful organisms
Why do you carry out risk assessments
Risk assessments involve identifying control measures to minimise risks
2 considerations needed when sampling species
Is the method appropriate for that species
How can the impact be minimised
4 different sampling methods and what types of organisms they are used for
Quad-rats ~ slow moving or sessile
Point count ~ birds
Capture ~mobile species
Camera trapping ~elusive species
What is an elusive species and which 2 sampling methods are used
Elusive species are those who are difficult to sample through normal observation
Direct and indirect ~ scat sampling or camera trapping
Name 3 ways we can identify organisms in a sample
DNA analysis, Biological keys, classification guides
Definition of taxonomy
The scientific study of naming describing and classifying organisms
Define classification
The process by which scientists group living organisms
What does a polygenic tree show
Shows evolutionary history and relatedness
What’s the order of the hierarchy of biological classification
Life -> Domain-> Kingdom-> Phylum-> Class-> Order-> Family-> Genus-> Species
What’s the difference between the convergent and divergent evolution
Divergent- development of the different lifeforms from a common origin
Convergent- separate evolution of similar phenotypic adaptations
List 5 model organisms
Bacterium Flowering plant Nematode Arthropod Chordates
Why do we study model organisms
Easily studied and kept
Useful for more harmful examples
What is an indicator species
An indicator species is an organism whose presence absence for abundance reflects a specific environmental condition
What is Mark and we capture techniques for?
To estimate population were to be impractical to count every individual
List five methods of marking organisms
Banding Tagging  painting Surgical implantation Hair clipping
What does N stand for
Population
What does M stand for
Number marked on first count
What does C stand for
Number captured on second count
What does R stand for
Recaptured organisms
List three assumptions of the mark and we capture technique
No emigration /immigration
 all animals have an equal chance of being captured
Marked individuals mixed fully with the population
What is the study of animal behaviour
Ethology
What is anthropomorphism
Allocation of human characteristics to the behaviour of animals
List three measurements we can take to try and quantify animal behaviour and explain what they mean
Latency is the time taken between stimulus and response
Duration is how long the behaviour occurs for
And frequency is how many times behaviour occurs in a certain time frame
What is an ethogram
And I think Graham is a list of species specific behaviours to be observed and recorded in a study
