1. **Death Rate Impact:** High death rates can hinder population growth ([1]).

2. **Road Mortality Effects:** Road mortality reduces population growth rates in mammals ([2]).

3. **Population Density Stress:** Increased population density can lead to lower birth rates and higher mortality in animals ([5]).

4. **Human-Induced Mortality:** Larger mammals face higher human-induced mortality, impacting their populations ([4]).

5. **Age-Specific Mortality:** Understanding age-specific mortality is crucial for assessing suffering in animal populations ([7]).

6. **Population Limiting Factors:** Population density significantly affects juvenile and adult mortality ([9]).

The relationship between death rates and population dynamics is intricate, influenced by factors like external threats, environmental conditions, and species-specific characteristics. Understanding these dynamics is crucial for wildlife management and conservation efforts.
