        Get a brief overview of Costa Rica's stunning Santa Rosa National Park, home to many endangered plants and animals—including ants with surprising strategies for survival. This is the first installment in a series of video journals by Dr. Corrie Moreau and her team documenting their 2012 expedition to catalog and study ant diversity in the Guanacaste region. During the trip, team members collected ant specimens, reared live ants on special diets, and took samples of several ant species that will be studied back home at The Field Museum. By learning more about the relationship between diet, anatomy, and species diversity, the team hopes to better understand the mechanisms of evolution that affect all life on Earth.

          Meet the mighty leafcutter ants—some of the world's first farmers—which use their leafy haul as the fodder for a fungal garden that feeds a colony of millions. This is the fourth installment in a series of video journals by Dr. Corrie Moreau and her team documenting their 2012 expedition to catalog and study ant diversity in the Guanacaste region. During the trip, team members collected ant specimens, reared live ants on special diets, and took samples of several ant species that will be studied back home at The Field Museum.

                Ulrich Mueller, professor of integrative biology at The University of Texas at Austin, has spent most of his professional life peering deep into the evolutionary history of leafcutter ants, a species that evolved the ability to cultivate crops tens of millions of years before humans did. In this video Mueller visits some leafcutter colonies at the Brackenridge Field Laboratory, in Austin, and reflects on what fascinates him about the ants and their co-evolutionary relationship to the fungus species they farm.

                    Leaf-cutter ant societies are based on ant–fungus mutualism, a symbiosis between ant and fungal species. The ants actively cultivate fungus much like humans farm crops as a food source. The ants and fungi are dependent on each other for survival. They grow this fungus by creating gardens with leaf mulch, which is why they can be seen in their thousands carrying leaves through the forest to their nests. The ants have evolved to change food plants constantly, preventing a colony from completely stripping off leaves and thereby killing trees, thus avoiding negative biological feedback on account of their sheer numbers. However, this does not diminish the huge quantities of foliage they harvest. Once foraging workers locate a resource in their environment, they lay down a pheromone trail as they return to the colony. Other workers then follow the pheromone trail to the resource. As more workers return to the nest, laying down pheremones, the stronger the trail becomes. The strength to which workers adhere to the trail depends mostly on environmental factors, such as the quality of the resource. Colonies can contain more than 8 million ants, mostly sterile female workers.

                      Some studies estimate that ants make up an amazing 30 percent of the total biomass of Earth's tropical rain forests, far exceeding that of mammals. Here are leaf cutter ants taking their dismantled leafs back to their nests in Costa Rica's Osa Peninsula
