The Venezuelan scientist Emperatriz Gamero, a researcher at the Smithsonian Conservation Biology Institute, leads one of the most relevant studies for the protection of the Margarita capuchin monkey (Sapajus apella margaritae), an endemic primate of Margarita Island, classified as Critically Endangered.
Educated at the Central University of Venezuela, Gamero serves as a fellow at the Center for Conservation Genomics, where she conducts genetic research applied to threatened species. Her work focuses on analyzing the genetic diversity of this small and isolated population, whose long-term viability is seriously compromised.
Key Scientific Findings
The study, based on molecular phylogenetics, provides solid evidence about the ancestral origin of the Margarita capuchin monkey:
- It rules out that it is a recent introduction.
- It confirms that it arrived on the island through an ancient colonization event.
- It reveals a low genetic variability, typical of isolated island populations, which reinforces the urgency of science-based conservation strategies.
Gamero warns: “Understanding the origin and genetic diversity of the species is key to making correct decisions. When populations are small, any management error can accelerate their disappearance.”
Current Threats
The findings have direct implications for the management of the species, which faces:
- Illegal pet trade.
- Introduction of other continental capuchins, causing hybridization.
- Reduction of population size, with risk of inbreeding and loss of genetic diversity.
The Margarita Capuchin Project
Since 2017, Gamero has been part of the Margarita Capuchin Project, a multidisciplinary initiative that brings together scientists, environmental authorities, and local communities. Her contributions have enabled:
- Establishing a robust genetic base for long-term conservation.
- Developing diagnostic tools to identify genetically pure individuals and detect hybrids.
- Promoting environmental education and community work on the island to reduce illegal wildlife trade.
Ecological Importance of the Margarita Capuchin Monkey
The Sapajus apella margaritae plays a fundamental role in the ecological balance of the island:
- Seed disperser: contributes to the regeneration of forests and jungles.
- Insect regulator: maintains ecosystem health.
- Environmental indicator: its presence reflects the integrity of the forests.
- Intelligence and adaptation: it is one of the most intelligent monkeys in the New World, capable of using tools to obtain food.
Conservation and Challenges
The Margarita capuchin monkey is on the IUCN Red List and Venezuela’s national list as a critically endangered species since 1996. Its main threats are habitat fragmentation, illegal hunting, and wildlife trafficking. Projects like the Margarita Capuchin Project aim to protect it in areas such as the Cerro El Copey National Park, where it acts as a key piece for local biodiversity.
Emperatriz Gamero’s work demonstrates how applied science can make a difference in the conservation of unique species. The case of the Margarita capuchin monkey is an example that the loss of biodiversity in megadiverse regions like Latin America has global implications. Protecting it is not just a local challenge but a shared responsibility to ensure the health of ecosystems and the natural heritage of humanity.
