Knowra Behavioral ecology Behavioral ecology Behavioral ecology studies how behavior relates to organisms’ environments and evolutionary fitness, including how natural selection shapes behavioral strategies.
Optimal foraging theory : A framework for predicting how animals choose food and foraging methods to maximize benefits relative to costs. It models feeding decisions as strategies shaped by energetic gains, risk, and search time.
Natural selection : The process by which heritable traits that improve reproductive success become more common across generations. It provides the evolutionary mechanism through which behavioral differences can spread.
Sexual selection : Selection arising from differences in mating success, including competition for mates and mate choice. It explains behaviors that increase mating success, even when they reduce survival.
Behavioral genetics : The study of genetic contributions to variation in behavior, often alongside environmental influences. It asks how inherited differences contribute, while behavioral ecology emphasizes environmental and fitness relations.
Game theory : The mathematical study of strategic interactions among decision-makers whose outcomes depend on one another’s choices. It predicts when cooperation, competition, or conflict can be favored among interacting organisms.
Fitness (biology) : An organism’s contribution of viable offspring to future generations, relative to others in its population. Behavioral ecology evaluates strategies by their effects on reproductive success.
Parental investment : Resources and effort devoted to offspring that reduce a parent’s capacity to invest elsewhere. It helps predict which parent cares for offspring and how much care is provided.
Comparative psychology : The study of behavior and cognition across animal species, often using controlled experiments. Its focus on learning and cognition differs from explanations centered on ecological consequences and selection.
Evolutionarily stable strategy : A strategy that, once common in a population, cannot be invaded by a rare alternative strategy. It identifies behavioral outcomes resistant to invasion by competing strategies.
Phenotypic plasticity : The capacity of one genotype to produce different phenotypes in response to environmental conditions. Flexible behavior can let the same organism respond to changing environments.
