Lecture 4 Flashcards
Environmental conditions an animal needs to survive and reproduce (their specific habitat)
Niche
2 species can’t live in the
same area for the same resources (can be slightly different locations to work)
Niche Rule
Will leave food area when
the net calorie intake matches other average food sources – more time in farther
and thicker areas
Marginal Value Theorem
Slowing and
turning when there is more food, moving straight and quickly once thinned out.
Area Restricted Search Hypothesis
The mental representation for what the animal is seeking.
Search Image defined
Balancing efficiency and protection by getting food
to a place with multiple escape routes, in the center – males want these territories
Central Place Foraging
Males need females to mate with
Limiting resource for males
females need food to successfully ovulate and have offspring
Limiting resource for females
Round-trip move for a more food-rich habitat.
Migration
Response to food aggression by conspecifics: aggression will decrease when territories are solid – females will also
go to them and mate with that territory’s male – territorial vs floaters.
Territorial behavior
Cooperation between animals to get food:like working together to take down a bigger animal because more to share, birds communicating food in a flock.
Mutualism defined
between different species → a lot more intense
Interspecific feeding competition
Same species feeding competition
Intra-specific feeding competition
Increased predator detection and foraging, will eat different food items so not as much competition
Why mixed species flocks work
Both predator and prey are constantly adapting to catch/escape the other – adaptations to move faster from both.
Predator/prey arms race
