Strength in numbers
In some species, living in groups ensures more success in this, which increases the survival of genes.
What is reproduction?
Solitary living reduces the risk of this.
What are diseases/parasites?
More individuals packed together increase the risk of this spreading
What are diseases/parasites?
Finding this vital partner may be harder when living alone
What is a mate?
Some animals huddle together in groups to conserve heat in cold environments, using social behavior to improve this physiological process.
What is thermoregulation?
Living alone allows this animal to avoid battles over food, mates, or territory, saving them this.
What is energy?
While groups can offer safety in numbers, they can also attract more attention from predators, as larger gatherings increase this type of risk.
What is predation risk?
What is safety in numbers?
Ants, bees, and naked mole-rats exhibit this extreme form of social organization, characterized by cooperative brood care, overlapping generations, and division of labor.
What is Eusociality?
Solitary living makes some species more efficient in this.
What is hunting?
In large groups, individuals often face increased competition for limited food, shelter, and mates, leading to higher levels of this social conflict.
What is intraspecific competition?
Unlike group-living species where member help protect or feed offspring, solitary animals must do this on their own.
What is care for their young?
A phenomenon in behavioral ecology where the risk of predation for an individual decreases as the number of individuals in a group increases.
What is the dilution effect?
Solitary animals often rely on this adaptation, blending into their surroundings, to avoid predators without the protection of a group
What is cryptic coloration?
In some group-living species, dominant individuals kill the offspring of some females to reduce competition for resources or mating.
What is infanticide?
Solitary animals lack this group advantage, which helps detect predators more quickly.
What is many eyes watching for danger?
