Intro to the LPR
Which of the following populations has depreciated the most?
a) Freshwater Populations
b) Marine Populations
c) Terrestrial Populations
a) Freshwater Populations
What is biodiversity?
The variability of living organisms.
What are tipping points?
Cumulative impacts of environmental pressure that reaches a threshold that triggers a disaster. Pushing to a "point of no return" (irreversible change).
Which continent/region has experienced the highest ecological rate of decline?
The Carribean
What are the 5 kinds of biodiversity?
Genetic, Species, Population, Ecosystem, and Ecosystem Function diversity.
How many fast approaching global tipping points have scientists identified?
a) 4
b) 5
c) 6
d) 7+
e) None of the above
Which two continents/regions have experienced the smallest rate of ecological decline?
Central Asia & Europe
Name 3 driver's of change.
Habitat Loss/Degradation
Overexploitation
Climate Change
Pollution
Invasive Species/Genes
Disease
What are the two tipping points for the biosphere?
What are the three factors that impacted North America, Europe, and Central Asia's biodiversity negatively in the past which shows today through their lower declination rate?
Industrialization, Monoculture, Surge in technological advancements.
What is the LPI? What does it track? Is it a short term or a long term indicator?
The LPI is the living planet index and it tracks the size of animal populations as well as how they are changing. The LPI is a long term indicator.
If the subpolar gyre were to collapse, what system would be impacted and what would it do?
a) Cryosphere, Sea level rise
b) Cryosphere, Change weather patterns
c) Ocean Circulation, Mass release of carbon
d) Ocean Circulation, Change weather patterns
d) Ocean Circulation, Change weather patterns
In this scenario, country A has an early onset of mass industrialization whilst country B remains unchanged and progresses slower technologically then country A. After sixty years, suddenly a massive decline in biodiversity occurs across the globe for a year. Which country has a higher rate of declination for that year and why?
Country B. This is because country A's biodiversity has already been impacted in the past, and so within the year, country B will suffer more than country A.
The same species (falling under the umbrella of species A) of moth live in different geographical locations. Species A1 lives in a very forested location and mostly travels in small groups. Species A1 has also developed a small, moss like coating. Species A2 lives in a colder climate with fewer trees. Species A2 travels in large groups. Species A2 has also developed a thin layer of fur. What factor(s) of biodiversity are present?
a) Genetic Diversity
b) Species Diversity
c) Population Diversity
d) Both A and B
e) None of the above
d) Both A and B
Why? - Both A1 and A2 are part of species A. They, however, live in different geographical locations and are exposed to different natural phenomena. This leads to population diversity being one of the factors as they are the same species but live within different populations. It also states that they have evolved as seen in their different adaptations which leads the other factor to be genetic diversity.
The coral reefs have two main functions that are critical to the protection of the earth and are part of one of the following tipping point systems.
a) Marine life protection, Carbon absorption, Ocean Circulation
b) Fish population protection, Air temperature maintenance, Ocean Circulation
c) Marine life protection, Sea level stabilization, Cryosphere
d) Marine life protection, Fish population protection, Biosphere
e) None of the above
d) Marine life protection, Sea level stabilization, Biosphere
