Ecological succession + Conservation

HideShow resource information
How does succession occur?
Colonisation by pioneer species - change in environment - enables other species to colonise - change in biodiversity - less hostile environment - reaches climax community
1 of 6
What happens at each stage in succession?
Certain species may be recognised, changing the environment so it becomes more suitable for others
2 of 6
What do changes in the abiotic environment result in?
Less hostile conditions and changing diversity
3 of 6
What features emerge during succession?
Less hostile environment, greater number and variety of habitats, increased biodiversity, more complex food webs, increased biomass.
4 of 6
What are the main reasons for conservation?
Ethical, economic, cultural, aesthetic
5 of 6
What does conservation of habitats sometimes involve?
Managing succession because once the climax community has been reached, the pioneer species may no longer be present because their habitats have disappeared or competition has increased
