Questions & Answers:
Q1: What does PVA stand for in conservation biology?
A) Population Variable Analysis
B) Population Viability Analysis
C) Population Validity Analysis
D) Population Vitality Analysis
A1: B) Population Viability Analysis
Explanation: Population Viability Analysis (PVA) is the correct term used to describe the process that assesses the probability of a species surviving under various environmental conditions.
Q2: PVA models are used to ______.
A) predict weather patterns
B) simulate population dynamics
C) assess economic viability
D) calculate genetic diversity
A2: B) simulate population dynamics
Explanation: PVA uses simulations based on demographic and environmental data to predict the future dynamics of a species' population.
Q3: True or False: PVA can predict the exact fate of a species.
A3: False
Explanation: PVA does not predict the exact fate but rather models probabilities and scenarios that can help in conservation planning.
Q4: The primary challenge in conducting PVA is:
A) the lack of interest in conservation
B) the ease of gathering data
C) extensive and accurate data requirements
D) finding suitable computer software
A4: C) extensive and accurate data requirements
Explanation: Gathering extensive and accurate data is challenging for PVA, especially for species that are elusive or rare.
Q5: PVA is important for:
A) creating zoos
B) urban development
C) conservation efforts
D) agricultural planning
A5: C) conservation efforts
Explanation: PVA provides a scientific basis for decision-making and prioritization in the protection of endangered species, which is essential for conservation efforts.
Q6: Fill in the blank: PVA simulations often incorporate scenarios like climate change and ______.
A6: habitat loss
Explanation: The passage mentions that PVA simulations include various scenarios, such as climate change and habitat loss, to understand their potential effects on populations.
Q7: True or False: PVA always requires the use of computer software.
A7: True
Explanation: The passage indicates that PVA often utilizes computer software to run simulations, though it does not state that it is always required.
Q8: Which of the following is not a factor usually considered in PVA?
A) Birth rates
B) Death rates
C) Color variations in species
D) Environmental variables
A8: C) Color variations in species
Explanation: PVA focuses on demographic data like birth and death rates and environmental variables rather than specific traits like color variations unless they directly impact survival rates.
Q9: Fill in the blank: Despite its challenges, PVA remains a cornerstone of ______.
A9: conservation efforts
Explanation: The passage concludes by reinforcing the importance of PVA in conservation, despite the difficulties in its application.
Q10: True or False: PVA simplifies the complexity of ecosystems in its models.
A10: False
Explanation: The passage acknowledges that ecosystems' complexity makes it challenging to account for every variable, indicating that PVA does not oversimplify these complexities.
