Increased intraspecific competition leading to higher mortality rates
Reduced reproductive success due to limited food and habitat

Study the following dataset and answer the question:
Species | Initial Population | Growth Rate (% per year) | Resource Availability Index (1-10) | Carrying Capacity | Observed Population After 20 Years |
Elk (National Park) | 300 | 10 | 6 | 1,000 | 950 |
Coyotes (Ecosystem) | 50 | 6 | 7 | 200 | 190 |
Fish (Reservoir) | 500 | 12 | 5 | 1,200 | 1,100 |
Rodents (Island) | 200 | 20 | 3 | 600 | 100 |
