Properties of Wildlife Populations Flashcards
What is a population? Metapopulation?
What are the components of a basic population model?
birth factors = sex ratio, recruitment, natality, age structure
death factors = disease, predation, harvest, auto collisions
immigration = coming into a population
emigration = leaving a population
What are the properties of a population?
What are general methods for determining population density?
What types of movement can affect population dynamics?
What are 3 patterns of distribution within a population?
Describe age structure. What would this look like for a declining population, growing population, stable population?
Compare stable vs. Stationary age distribution
How is sex ratio described?
Explain these graphs
Different reptiles have different patterns of sex distribution based on temperature while eggs are developing. In the first, higher temperatures result in a higher percentage of females. In the second, there is a window of idea temperatures that result in favorable distributions.
What is natality and how is it described?
What is survivorship and how is it described?
What is mortality and how is it described?
What is mortality rate and how is it described? What could explain the mortality rate curves for the species pictured?
The red deer and sheep pictured see spikes in mortality rate during their peak fertility years because they are sought after by hunters as trophies during those years
