RWANDA – A new study analyzing more than 20 years of data on wild mountain gorillas reveals that friendship among these primates is a double-edged sword, impacting their health and well-being in complex ways. The research, published in the journal *Proceedings of the National Academy of Sciences*, sheds light on the intricate social dynamics within gorilla troops and how these interactions influence individual fitness.
Researchers examined 164 mountain gorillas residing in Los Volcanes National Park, Rwanda. These gorillas typically live in groups of about 12, led by a dominant silverback male. the study explored how social connections affected the gorillas’ health, considering factors such as group size and stability.
The findings highlight significant differences between male and female gorillas. According to the study, female gorillas in smaller groups who maintained strong social bonds experienced fewer illnesses but also had fewer offspring. Conversely, females in larger groups, while more prone to illness, exhibited higher birth rates.
Male gorillas with robust social ties faced a different set of trade-offs. These males were more susceptible to illness but less likely to sustain injuries during conflicts.
Dr. Robin Morrison, a researcher at the University of Zurich and lead author of the study, noted the broader implications of these findings. “Having many strong social relations is usually very good, but sometimes it is not,” Morrison said. “Our study found that strong and stable social ties are generally related to less diseases in females, but more diseases in males.”
Morrison added, “We cannot be sure why this happens, but it truly seems that it is indeed not a simple issue of social contact that leads to a greater risk of illness. It is possible that males spend more energy by having narrow social ties, since they have to defend the females and This generates can reduce its immune function.”
The research delved into the strength of individual gorillas’ key social connections and their integration within the group. It also considered broader factors such as group size, stability, and conflicts with other groups. The results underscore the multifaceted forces shaping the evolution of social behavior.
dr. Sam Ellis, from the University of Exeter, emphasized the context-dependent nature of social behavior. “With these forces pushing in different directions, the social type ‘optimal’ will depend on sex, age, offspring and the widest social group of the individual,” Ellis said.
Ellis also noted the relevance to other social mammals, including humans. “In humans and other social mammals, the social surroundings is one of the strongest predictors of health and life expectancy. But our study shows that it is not simply that having more and more social links is always better. In some situations, social features that we previously considered maladaptive can have crucial benefits.”
Long-Term Studies Key to understanding Sociability
Dr. Tara Stoinski, executive director and scientific director of the dian fossey gorilla foundation and a co-author of the study, highlighted the importance of long-term research. “This article highlights the incredible value of long -term studies to deepen our understanding of the evolution of sociability and how the benefits or costs of sociability may vary considerably in different environments,” Stoinski said.
A recent study,analyzing over 20 years of data on wild mountain gorillas,reveals that social bonds among these primates are a double-edged sword. These relationships impact their health and well-being in complex ways. The research, published in the Proceedings of the national Academy of Sciences, examines the intricate social dynamics within gorilla troops and how these interactions affect individual fitness.
Where was this study conducted?
The study focused on mountain gorillas residing in Los Volcanes National Park, Rwanda.
How many gorillas were examined in the study?
Researchers examined 164 mountain gorillas as part of the study.
How are gorilla troops structured?
Gorilla troops typically consist of about 12 individuals and are led by a dominant silverback male.
The study explored how social connections affected the gorillas’ health, considering factors such as group size and stability.
What are the key findings of the study regarding females?
The study found significant differences between male and female gorillas. For female gorillas, the research showed:
Smaller groups: those who maintained strong social bonds experienced fewer illnesses but had fewer offspring.
Larger groups: Those in larger groups were more prone to illness but exhibited higher birth rates.
What trade-offs did male gorillas experience?
Male gorillas with robust social ties faced a different set of trade-offs:
They were more susceptible to illness.
they were less likely to sustain injuries during conflicts.
What broader implications did the study uncover?
Dr. Robin Morrison, a researcher at the University of Zurich and lead author of the study, noted that the findings show “Having many strong social relations is usually very good, but sometimes it is indeed not.” The study found that strong and stable social ties are generally related to less diseases in females, but more diseases in males.
The researchers suggest that males might spend more energy defending the females within their group, which could potentially reduce their immune function.
The research delved into the strength of individual gorillas’ key social connections and their integration within the group. It also considered:
Group size
Group stability
Conflicts with other groups
Dr. Sam Ellis, from the University of Exeter, emphasized that the “optimal” social type depends on several factors:
Sex
Age
Offspring
* The wider social group.
The study’s findings are relevant to humans and other social mammals because “the social surroundings is one of the strongest predictors of health and life expectancy.” Though, the study shows that “having more and more social links is not always better.” In some situations,social features previously considered maladaptive can have crucial benefits in humans.
