There are currently no protected insect species on the Galápagos Islands. However, several endemic insect species live here, including several species of carpenter ants. These ants are unique to the Galápagos Islands. Protecting them and studying their biology is crucial to preserving the islands' unique biodiversity. The Galapagos Ant Project is a pioneering research project dedicated to this important task.
Led by Dr. Henri Herrera, an international team of researchers is studying the biology and evolution of both endemic and invasive carpenter ants on the Galápagos Islands. By combining ecological, genetic, and morphological data, the researchers hope to build a comprehensive picture of these ant species. The project aims to study the genetic and optical differences between the different ant populations and to develop conservation measures.
Project Background
Recent evidence shows that geographic barriers, such as mountains, the sea, or lava flows on the Galápagos Islands, promote genetic diversification, i.e. the splitting of a line of descent to occupy ecological niches, which can lead to the emergence of new species. While many studies have examined the diversification of animals such as giant tortoises, lizards and snails, the evolution of insects, especially ants, remains largely unexplored.
Camponotus ants play an important role in the island's ecosystem, but little is known about their behavior and ecology.
Camponotus planus and Camponotus macilentus are species of army ants native to the Galápagos Islands, known for their impressive size and behavior.
Camponotus planus, also known as the flat horse ant, lives mainly in tropical and subtropical regions. They often build their nests in dead trees or in moist soil. The ants are active during the day and feed on nectar, plant sap and small insects.

Camponotus macilentus, also known as the Slender Carpenter Ant, is found in similar habitats, but prefers dry and warm areas. Their nests are usually found under stones or in dry pieces of wood. These ants are also active during the day and feed similarly to Camponotus planus.

Both ant species play an important role in the Galapagos ecosystem, pollinating plants and controlling pests. They are fascinating examples of the diversity and adaptability of the ant world.
Project goals
- To study the biology of endemic and invasive carpenter ants: The project focuses on two endemic species (Camponotus planus and Camponotus macilentus) and one invasive species (Camponotus zonatus). The goal is to understand the distribution, behavior, and ecological interactions of these species.
- Genetic analyses: By sequencing the genomes of different ant populations, we will investigate the genetic differences and adaptations of ants to different island environments.
- Morphological studies: Extensive morphological data will also be collected to document the physical differences between ant species and populations.
Preliminary results from the project already show that endemic carpenter ants are increasingly being outcompeted by invasive species. This is of particular concern because native ant species often live in narrow ecological niches and have important interactions with local flora and fauna.
Importance of the Project
This research project is the first of its kind to focus on the Neotropics and island ecosystems. The data obtained will be crucial for the conservation of the endemic ants of the Galápagos Islands and the preservation of their ecosystem functions. In addition, the project will provide valuable information for conservation authorities to develop and implement targeted conservation measures.
The Galapagos Ant Project needs financial support to achieve its ambitious goals. Conducting field work and comprehensive genetic analyses requires significant resources. Your donations will go directly towards expeditions, genetic sequencing, and data analysis. Every contribution helps to protect the unique ant species of the Galápagos Islands and to conserve an important part of the world's natural heritage.
Your support makes it possible to
- Conduct expeditions to other islands to find previously undiscovered populations and document their ecological interactions.
- Utilize genomic analysis, as genome sequencing and analysis is important for studying the genetic differences and adaptations of ants.
- Conduct ecological studies to better understand the interactions between ants and native flora and fauna.
The combination of modern landscape and population genetic techniques with traditional ecological and morphological studies will provide critical data for the conservation of the ants and the entire ecosystem of the Galápagos Islands. This knowledge will allow conservation authorities to develop and implement targeted and effective conservation measures.
The Galapagos Ant Project is a groundbreaking research project that is the first to comprehensively study the genetic and ecological diversity of carpenter ants on the Galapagos Islands. It will provide valuable data for conservation and help preserve the unique biodiversity of the Galápagos Islands. With your support, this project can make a significant contribution to the conservation of endangered insect species and the biodiversity of the Galapagos Islands.
