Fray Jorge National Park

How global change affects food webs

The Kartzinel Lab is home to the third (and fourth!) generation of researchers to lead the longest-running ecological field experiment of its kind in South America: the classic Fray Jorge Long-term Ecological Research Program. This experiment started in 1989 and has documented effects of small mammal herbivory, invasive species, and rainfall variability on populations of both plants and small mammals in what is now the longest-running experimental field research program of its kind. Together with a team of investigators in Chile and the US, we are modernizing our understanding of how resource use and foraging behaviors are influenced by climatic variability

The Fray Jorge Long-term Ecological Research Program is a sentinel site for monitoring phenomena such as El Niño and climate change, and their impact on biodiversity. We work to monitor and understand interactions between plants, small mammals, birds, predators, and arthropods
