- Populations and Sustainability
- Factors determining final size of a population
- Abiotic
- Biotic
- Predator-Prey relationships and how possible effects on size of each population
- The larger the prey population, the larger the predator population will be come as a result
- Due to the larger predator population size, the prey population size decreases
- The smaller the prey population, the smaller the predator population will become
- Due to the decreased predator population size, the prey population size increases
- The larger the prey population, the larger the predator population will be come as a result
- Due to the larger predator population size, the prey population size decreases
- The smaller the prey population, the smaller the predator population will become
- Due to the decreased predator population size, the prey population size increases

- Methods of sustainable timber production
- Selective felling
- Coppicing
- Elm trees. Shoots develop when parent tree is felled. After a few years, these shoots are felled.
- ***** Felling
- Small patches of area are cleared at one time. Soil erosion and loss of species is avoided.
- Management and reclamation of an ecosystem
- Reasons for conservation of biological resources
- Effects of humans on the Galapagos Islands
- Cats/ Dogs/ Goats
- Lonesome George
- New diseases
- Cats/ Dogs/ Goats

- Conservation
