- The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services published a report in 2019 that described several negative effects that humans have had on biodiversity and ecosystem services. They highlighted and ranked five drivers of these negative effects. Which of the following has had the greatest overall impact on biodiversity and ecosystem services? A. Pollution B. Direct exploitation of organisms C. Invasive species D. Climate change E. Changes in land use and sea usearrow_forwardA conservation biologist has been asked to explain why it is important to protect biodiversity. She would list all of the following reasons except for which one? A. Humans are dependent on many species for food, medicines, fiber, and other necessities. B. Biodiversity can be exploited indefinitely for the profit of humans. C. Other species have inherent value and humans have a moral obligation to protect them. D. Biodiverse ecosystems provide ecosystem services that sustain all life on Earth. E. Biodiversity provides emotional and physical health benefits by providing places for humans to visit for wonder, insight, and exercise.arrow_forwardWhich of the subsequent options is not included in the red list criteria for species classified as "critically endangered"? 1. The population is projected to decrease by 25% or more within a span of 3 years or 1 generation. 2. The species possesses a limited range of less than 100km2 in a solitary location, and there is evidence of or anticipated habitat loss, fragmentation, ecological imbalance, or significant commercial pollution. 3. The likelihood of extinction exceeds 50% within a timeframe of 10 years or 3 generations. 4. The overall population size consists of fewer than 200 mature individuals.arrow_forward
- Which of the following is one of the biggest threats to biodiversity? A. Invasive species B. Land protection C. Ecological conservation D. Habitat restorationarrow_forwardIn landscape ecology, the matrix is the area surrounding a habitat patch. The matrix can affect a species living in the habitat patch by altering: O A. Dispersal between patches B. The availability of resources C. The abiotic environment in patches D. Our appreciation of Keanu Reeves' acting skills E.

- Habitat fragmentation can reduce biodiversity by a. introducing more native species into a habitat b. sterilizing for pollution control C. decreasing human use of natural resources d. eliminating vast tracts of forests e. withdrawing an essential resource from native speciesarrow_forwardWhich of the following is not true of a population of largepredators in a small reserve?a. The species may disappear from the reserve.b. The species will probably undergo a populationexplosion.c. The species will probably lose genetic diversity.d. The species may overeat its prey, causing a reduction inprey population.arrow_forwardEcological dominants are a. the most numerous or make up the most biomass within a community. b. are species that may not be the most numerous within a community, but whose role is so significant that its absence would bring about considerable change. c. species that are introduced into an area where they do not naturally occur. d. the most important species on the planet.arrow_forward
- The Canary Islands are a volcanic island chain off the western coast of Africa with a larger percentage of specialist species than generalist species. If an invasive species is introduced to one of the Canary Islands, which of the following represents an immediate impact? (NOTE: a specialist species has a narrow ecological tolerance, while a generalist has a wide ecological tolerance) The populations of the invasive species on the Canary Islands will decrease as predation increases. The population of the invasive species on the Canary Islands will decrease because they were outcompeted by native specialist species. The populations of both the invasive species and the specialist species on the Canary Islands will remain the same as a result of resource partitioning. The populations of the specialist species on the Canary Islands will decrease as competition for resources increases.arrow_forwardHabitat fragmentation results from human activities that change large blocks of landscape, leading to many negative effects on species and ecosystems. Which of the following is not one of the possible consequences of fragmentation? A. reduction of available habitat O B. increasing degradation of habitat patches C. increasing wind speeds and temperatures at patch edges D. spatial isolation of patches E. increase in top predators present in patchesarrow_forwardAt any point in time, a number of environmental objectives must be met with a limited amount of economic resources. This means that once an environmental problem is identified, they have to be prioritized. In general, this is done using scientific valuation of the relative risk to human health and the ecology of a given environmental hazard - a procedure known as: A. Biodiversity B. Public Goods C. Risk Assessment D. Profit maximizationarrow_forward
