Summary Introduction
Introduction:
The conservation biology is the field of science that deals with the management of nature and biodiversity on Earth. It aims to protect the species, their habitats, and ecosystem from the extinction and erosion. The person who studies conservation biology is known as a conservation biologist. The conservation biologists conduct population viability analysis.

- Which 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_forwardAssuming all other factors are equal, which statement about the success of core natural areas as a conservation measure is false? OA. Areas with compact shapes are superior to areas with less compact shapes. B. One large reserve is superior to a few small reserves with the same total area. C. Several reserves far apart are superior to the same number of reserves close together. O D. Reserves connected by habitat corridors are superior to unconnected reserves. Areas encompassing a range of vegetation types are superior to those with a uniform composition. E.arrow_forwardMatch the approach to protection with the example from the academic literature. Species approach Hotspot approach Ecosystem approach 1. Wolf reintroductions into the Yellowstone environment restored riparian species and increased biodiversity because wolves controlled the numbers of elk and coyotes which allowed plants, beaver, and foxes to rebound (Ripple and Beschta 2003). 2. The creation of a reserve protects the red-brown treecreeper (Climacteris picumnus). This approach looks to accommodate processes that threaten species viability, such as fragmentation and feral predators (Nicholson et al. 2013). 3. Species richness of tiger beetles, Cicindelidae, is positively correlated with bird and butterfly diversity across North America, Australia, and the Indian subcontinent (Reid, 1998).arrow_forward
- In 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. A, B and C are correctarrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardThe 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.
