Unit 2 - Field Techniques Flashcards
What are some hazards associated with fieldwork?
Hazards in fieldwork include adverse weather
conditions, difficult terrain, problems
associated with isolation, and contact with harmful organisms
What is risk?
Risk is the likelihood of harm arising from
exposure to a hazard.
What does a risk assessment do?
Risk assessment involves identifying control measures to minimise risk.
What are control measures?
Control measures include appropriate
equipment, clothing, footwear, and means of
communication
How should sampling carried out?
Sampling should be carried out in a manner
that minimises impact on wild species and
habitats
What consideration should be taken when sampling?
Consideration must be given to rare and
vulnerable species and habitats that are
protected by legislation
What is a point count?
A point count involves the observer recording
all individuals seen from a fixed point count
location
What can point count results be compared to?
This can be compared to other point
count locations or with data from the same
location gathered at other times.
What are quadrats?
Quadrats, of suitable size and shape, or
transects are used for plants and other
sessile or slow-moving organisms
What are capture techniques examples?
Capture techniques, such as traps and nets,
are used for mobile species
How can elusive species by directly sampled?
using camera traps
How can elusive species by indirectly sampled?
scat sampling
How can an organism be identified?
classification guides,
biological keys, or analysis of DNA or protein
How can organisms be classified?
Organisms can be classified by both
taxonomy and phylogenetics.
What is taxonomy?
Taxonomy involves the identification and
naming of organisms and their classification
into groups based on shared characteristics
What is taxonomy classification based on?
Classic taxonomy classification is based on
morphology.
What is phylogenetics?
Phylogenetics is the study of the evolutionary
history and relationships among individuals
or groups of organisms
What does phylogenetics use and what does it create?
Phylogenetics uses heritable traits such as
morphology, DNA sequences, and protein
structure to make inferences about an
organism’s evolutionary history and create a
phylogeny (or phylogenetic tree)
What can phylogenetics create?
create a
phylogeny (or phylogenetic tree)
What is morphology?
Internal and external structures of an organism
What taxonomic group is an Ecoli?
Bacterium
