What was the Illinois prairie rescue strategy?
What was the Illinois prairie rescue strategy?
What strategy was used to rescue Illinois prairie chickens from a recent extinction vortex? Introducing individuals from other populations to increase genetic variation.
How does the rate of extinction today compare with the rates in the past?
How does the rate of extinction today compare with the rates in the past? The rate is much higher today than it has been, on average, in the past. Over the past 580 million years, how has biodiversity changed? It has generally increased but with punctuations of extinctions.
Which of the following strategies would most rapidly increase the genetic diversity of a population in an extinction vortex think of small population approach?
Which of the following strategies would most rapidly increase the genetic diversity of a population in an extinction vortex? Introduce new individuals from other populations of the same species.
Which statement best explains how the elimination of ice covered ecosystems affects the rise or fall in global temperature?
Which statement best explains how the elimination of ice-covered ecosystems affects the rise or fall in global temperature? More reflective surfaces of ice are replaced with darker, more absorptive surfaces, thereby contributing to the warming trend.
What helps with restoration of some forests and prairies?
By spreading the seeds of prairie plants onto old farmlands, land managers can restore these ecosystems. As new grasslands grow, managers periodically conduct prescribed fires and remove weeds with herbicides to promote the prairie plants. In time, insects and birds will return to restored prairies from nearby areas.
What management strategies can be used to restore a disturbed prairie community?
Long-term management methods of prairie restorations including burning, grazing, mowing and haying; all are used to maintain floral diversity, remove woody or invasive species and reduce weed growth. Burning was by far the most common method of site management, with over 90% of managers burning with some frequency.
Why is the current extinction rate so high?
The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
What is the current extinction rate?
These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true – i.e. that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year.
What is the most effective way to preserve species diversity?
6 Ways to Preserve Biodiversity
- Support local farms.
- Save the bees!
- Plant local flowers, fruits and vegetables.
- Take shorter showers!
- Respect local habitats.
- Know the source!
Which of the following strategies would most rapidly increase the genetic diversity of a population that is starting to go extinct?
Which of the following strategies would most rapidly increase the genetic diversity of a population in an extinction vortex? Introduce new individuals transported from other populations of the same species.
Which of the following has been predicted and observed as a consequence of global climate change quizlet?
Which of the following has been predicted, and observed, as a consequence of global climate change? Decrease in artic sea ice, coastal flooding, changes in the distribution of species, and wildfires. All answers are correct.
What is an effort to develop manage and conserve Earth’s resources to meet the needs of people today without limiting the ability of future generations to meet their needs?
“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
