Summary
Competition can drive differences in how animals adapt their behavior. This study shows that social environment and environmental patchiness influence individual behavioral plasticity in sticklebacks.
Area of Science:
- Behavioral ecology
- Evolutionary biology
- Animal behavior
Background:
- Individuals within a population exhibit variation in responses to environmental changes.
- Theoretical models suggest competition in heterogeneous environments may foster between-individual variation in behavioral plasticity.
Discussion:
- This study investigated behavioral plasticity in sticklebacks across varying competition levels and social contexts.
- Behavioral plasticity varied significantly when social dynamics affected foraging opportunities, supporting theoretical predictions.
- The stability of an individual's behavioral plasticity in new social groups was contingent upon environmental heterogeneity.
Key Insights:
- Social competition is a key factor promoting individual differences in behavioral plasticity.
- Environmental heterogeneity modulates the influence of social factors on behavioral plasticity.
- Behavioral plasticity is not fixed and can be influenced by ecological and social conditions.
Outlook:
- Further research can explore the genetic and developmental underpinnings of behavioral plasticity.
- Understanding the drivers of behavioral plasticity is crucial for predicting population responses to environmental change.
- This work provides a foundation for future studies on the evolution of adaptive behaviors in variable environments.

Fixed Action Patterns
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
Competition
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.
Predator-Prey Interactions
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
Instinctive Drift
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
