Across
  1. 1. a search image hypothesis, predators more efficient at hunting if they focus on a single stimulus associated with one prey item
  2. 3. value of the next best alternative that is foregone when a choice is made
  3. 5. costs of being a generalist
  4. 7. occurs when a trait with adaptive benefits can also have maladaptive effects
  5. 9. genetic changes that occur by chance rather than by natural selection
  6. 11. diversification of plant-feeding insects driven by the sheer diversity of niches associated with plants, allowing for multiple rounds of host switching
  7. 14. speciation is thought to be driven by specialized populations from a generalist ancestor, with episodic host-breadth expansions
  8. 15. aka realized niche, the fundamental niche after considering interactions with other species
Down
  1. 2. referes to the ability of an individual to adjust their behaviour, skills, and responses
  2. 4. all of the abiotic and biotic environmental requirements for a species to persist
  3. 6. ecological generalism comes at the expense of less intense exploitation of specific resources; this tradeoff will promote the evolution of specialization
  4. 8. thrive in a wide range of environmental conditions, exhibiting significantly lower rates of speciation
  5. 10. finite amount of resources available for investment in various functions
  6. 12. narrower environmental tolerances or resource requirements
  7. 13. aka fundamental niche, all the environmental requirements for an organism to survive and reproduce
