Summary
This study provides the first evidence of extra-pair mating in Indri indri, the largest living lemur. This behavior may influence social dynamics and genetic diversity in lemur populations.
Area of Science:
- Primatology
- Behavioral Ecology
- Conservation Biology
Background:
- Indri indri, the largest living lemur, exhibits social monogamy.
- Extra-pair mating behaviors are observed in various socially monogamous species.
- Understanding mating strategies is crucial for lemur conservation.
Purpose of the Study:
- To present the first evidence of extra-pair mating in Indri indri.
- To discuss the implications of this alternative mating strategy on social and behavioral patterns.
- To explore the potential role of extra-pair mating in maintaining genetic variability.
Main Methods:
- Field observation in a mountain rainforest in eastern Madagascar.
- Behavioral monitoring of a wild Indri indri group.
- Analysis of social, territorial, spatial, and vocal behaviors.
Main Results:
- First documented evidence of extra-pair mating in Indri indri.
- Observed alterations in the adult female's social, territorial, spatial, and vocal behavior.
- Extra-pair mating identified as a potential alternative mating strategy.
Conclusions:
- Extra-pair mating occurs in Indri indri, challenging assumptions of strict monogamy.
- This behavior may lead to changes in group dynamics and individual behavior.
- Further research is needed to determine if extra-pair paternity contributes to genetic diversity.

01:20Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
01:20Evolutionary Psychology
Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...
01:06Fixed 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.
00:54What is Behavior?
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.
02:39Predator-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.
00:58Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
