Bаrk beetle оutbreаks аre increasing in many pine fоrests due tо warming temperatures. Higher temperatures allow the beetles to develop into adults more quickly, producing two adult generations per year instead of one. Large-scale infestations are causing widespread pine tree mortality. These trees play important roles in the ecosystem, including proving habitat for many species, maintaining soil health, and reducing harmful particulates in streams, which are important sources of drinking water for humans. Management strategies include cutting down affected trees and applying insecticides to control beetle populations. Scientists note that the negative effects on ecosystem services only become severe after approximately 50% of the trees in an area have died. Are developmental changes in the bark beetles an example of phenotypic plasticity? Explain your reasoning. (5 pts) Describe the response window—the period when these changes occur for this beetle—and discuss whether the response is likely to be permanent or reversible (5 pts) List one provisioning service and one regulating service that may be lost due to the bark beetle infestation. Be sure to note which one is the provisioning and which is the regulating service. (4 pts) What term describes the point at which ecosystem effects become severe after a critical threshold of 50% tree mortality is reached? (2 pt) The management strategy of cutting down affected trees and applying insecticides is an example of what type of conservation strategy? (2 pts)
