What does filching mean?

(fɪltʃ ) Word forms: filches, filching, filched. transitive verb. If you say that someone filches something, you mean they steal it, especially when you do not consider this to be a very serious crime.

What makes foraging behavior optimal?

Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. To maximize fitness, an animal adopts a foraging strategy that provides the most benefit (energy) for the lowest cost, maximizing the net energy gained.

Who came up with optimal foraging theory?

MacArthur

Which of the following is not required for a behavioral trait to evolve by natural selection?

Genes play a major role in behavioral aspects as they carry the information regarding behavior. This is not required for a behavioral trait to evolve by natural selection, because natural selection is not depends on the actions of genes.

What theory suggests that animals should maximize their energy gained per unit time?

Optimal foraging theory

Which two requirements must be met to demonstrate that animals plan for the future?

What 2 requirements must be met for the existence of future planning in animals? 1) Behavior must be novel, not innate. 2) Behavior cannot be tied to current motivational state of animal but to an anticipated state in the future. Case study of Western scrub jays and the ‘planning for breakfast’ experiments.

What is the premise of the optimal foraging model?

A key premise of optimal foraging theory is that animals have, through the process of natural selection, evolved behaviors that tend to maximize their rate of energy intake (see Pyke, Pulliam, & Charnov 1977; Krebs 1978, for reviews).

What is the basis of the behavioral trade off in ants observed by Nonacs and dill 1990 )?

What is the basis of the behavioral trade-off in ants observed by Nonacs and Dill (1990)? -The greater the food reward, the greater the willingness to take risks.

What is dietary breadth?

Diet breadth is a classic optimal foraging theory (OFT) model from human behavioral ecology (HBE). One or more foragers searches for resources and decides to take them according to rank. A forager will preferentially take highest ranked resources (providing the highest net return).

What does diet breadth mean quizlet?

diet-breadth model. predicts that when overall food density is high, it pays to specialize on the good items and to ignore the choices of lower food quality.

What is required for a behavioral trait to evolve by natural selection?

A behavior that is at least partly under genetic control can evolve through natural selection. However, being controlled by genes is not the only requirement for a behavior to evolve through natural selection. The individual performing the behavior also must have increased fitness due to the behavior.

Why do you think natural selection favors animals with the greatest reproductive success?

Answer: Natural Selection favors animals with greatest reproductive success because they have the potential to make different species. Take for example the frog. The frog is just a single animal with a wide range of species.
