application questions

Question 1

use examples of named taxa to explain how in-situ conservation can be improved by controlling temperature

Answer 1

• Tree seeds= some seeds of trees will only germinate after exposure to cold temperatures
• marine turtles= reduced temp of incubation will increase the number of eggs developing into male turtles

Question 2

use examples of named taxa to explain how in-situ conservation can be improved by controlling light

Answer 2

• woodland floor wild flowers= a reduction in the canopy layer will allow light to reach flowers for photosynthesis and growth

Question 3

use examples of named taxa to explain how in-situ conservation can be improved by controlling water availability

Answer 3

• marshland plants= reduce drainage of fields or the buildingof damns to create wetland habitats

Question 4

use examples of named taxa to explain how in-situ conservation can be improved by controlling nutrients

Answer 4

• grassland wild flowers= remove nutrient rich topsoil/ decrease use of fertilisers so wild flowers aren’t outcompeted by fast growing taller plants

Question 5

use examples of named taxa to explain how in-situ conservation can be improved by controlling PH

Answer 5

• aquatic insect larvae= neutralise acid from acid rain or from acid drainage of mine spoil

Question 6

use examples of named taxa to explain how in-situ conservation can be improved by controlling food availability

Answer 6

• provision of food species eg planting flowers which produce nectar for pollinators such as bees
• keeping cattle which produce dung to feed insects

Question 7

use examples of named taxa to explain how in-situ conservation can be improved by controlling predation

Answer 7

• the culling or exclusion of predatory species eg the culling of foxes in area of ground nesting birds

Question 8

use examples of named taxa to explain how in-situ conservation can be improved by controlling pollination

Answer 8

• planting seed mixes of flowering plants to maintain bees which are needed to pollinate wild flowers

Question 9

use examples of named taxa to explain how in-situ conservation can be improved by controlling seed dispersal

Answer 9

• the protection of species such as hippos or elephants which distribute the seeds of many plants

Question 10

use examples of named taxa to explain how in-situ conservation can be improved by controlling disease

Answer 10

• the control of species which are known to carry parasites or disease eg the grey squirrel to prevent the spread of squirrel pox to red squirrels
