21
Q

what does familiarity with taxonomic groupings allow?

A

predictions to be made between the biology of an organism and better-known (model) organisms

22
Q

what is convergent evolution?

A

similar structures that have evolved from different ancestors

23
Q

what is divergent evolution?

A

the accumulation of difference as species from a common ancestor undergo changes over time

24
Q

what does phylogenetics use to make an inference about evolutionary history?

A

traits such as morphology, DNA structures and protein structures

25
Q

what is the phylogenetic tree?

A

a diagrammatic hypothesis of relationships

26
Q

what are phylogenetics?

A

the study of the evolutionary history and the relationships among individuals/groups

27
Q

what do taxonomic groupings e.g. arthopods allow?

A

predictions and inferences to be made between the biology of an organism and model organisms

28
Q

what does king prawn curry or fresh green salad stand for?

A

kingdom, phylum, class, order, family, genus, species

29
Q

what is taxonomy?

A

the classification of life according to relatedness

30
Q

what is classification?

A

the method used to order living organisms and to help identify individual organisms

31
Q

in netting, what will affect what you capture?

A

the size of the net and the size of the mesh

32
Q

name the two capture techniques

A

pitfall traps, netting

33
Q

what is scat sampling?

A

an indirect method whereby animal droppings are collected in particular areas

34
Q

what does remote detection allow?

A

more elusive species to be observed without the observer being present

35
Q

what is remote detection?

A

camera traps that are triggered when wildlife is present

36
Q

what is a transect line?

A

a line along which different samples can be taken

37
Q

where are transect lines usually positioned?

A

where the terrain or abiotic factors are changeable

38
Q

how are point counts carried out?

A

by recording the organisms seen and heard from a stationary point

39
Q

what are the three sampling Rs?

A

representative, reliable source of data, random selection

40
Q

how should sampling be carried out?

A

in a manner that minimises impact
considering rare and vulnerable species and habitats protected by legislation

41
Q

what are carried out to minimise risks?

A

risk assessments

42
Q

what is a risk?

A

the likelihood of harm arising from a hazard

43
Q

when conducting fieldwork, what should be selected appropriately to avoid hazards?

A

clothing, footwear, supplies, means of communication

44
Q

when conducting fieldwork, which hazards and tests must be assessed first?

A

terrain, weather conditions, isolation, contact with harmful organisms
