10 Questions
What is the impact of unrestricted harvesting of trophy rams on trophy quality?
Unrestricted harvesting of trophy rams has contributed to a decline in the traits that determine trophy quality.
What have hunters selectively targeted when harvesting trophy rams?
Hunters have selectively targeted rams of high genetic quality before their reproductive peak.
What genetic effects might result from selective and severe wildlife harvesting?
Selective and severe wildlife harvesting might elicit an undesired evolutionary response and result in genetic deterioration of harvested populations.
What are some unexpected effects of selective wildlife harvesting?
Selective wildlife harvesting can have unexpected effects on genetically correlated traits, such as female body weight or disease resistance.
Why is it important for wildlife managers to consider genetic effects and evolutionary implications of harvest strategies?
It is important for wildlife managers to consider genetic effects and evolutionary implications of harvest strategies because the changes caused by selective harvesting can be extremely difficult to reverse.
What is the potential consequence of unrestricted harvesting of trophy rams on the traits that determine trophy quality?
A decline in the very traits that determine trophy quality.
How have hunters contributed to the depletion of genes that confer rapid early body and horn growth in trophy rams?
By selectively targeting rams of high genetic quality before their reproductive peak.
What is the possible evolutionary response to selective and severe wildlife harvesting?
An undesired evolutionary response when the target trait is heritable.
What are some potential unexpected effects of selective wildlife harvesting?
Unexpected effects on genetically correlated traits, such as female body weight or disease resistance.
Why is it important for wildlife managers to consider the genetic effects and evolutionary implications of alternative harvest strategies?
To prevent further genetic deterioration of harvested populations as anthropogenic selection pushes traits away from their naturally selected optima.
