Bsc3052 Conservation Biology Fsu Exam 2 Questions & Answers 2023/2024

Environmental Stochasticity {Ans: - Temporal variation in vital rates driven by changes in the biotic or abiotic environment - Local and small populations are often most at risk from environmental stochasticity - Increases extinction risk - Bad years are bad for the average growth rate - Strings of bad years can lead to extinction}Which stochastic processes would increase extinction rate for a MEDIUM sized population? {Ans: - Environmental stochasticity}Stochastic Models {Ans: - Give a range of outcomes from the same initial conditions - Most important when studying small populations and making short to medium term predictions - Most population viability analyses will include some form of stochasticity}Sources of Variation {Ans: - Environmental stochasticity - Demographic stochasticity - Catastrophes}Catastrophes {Ans: - Hard to predict or model but ultimately may be a common contributor to extinction - Multiple viable populations are necessary to be resilient to a catastrophe - Spatial variation in the environment can help avoid extinction - Not predicable from historical data}Conservation genetics {Ans: - Application of genetic techniques to conservation problems}
