Dietary overlap among ruminants, geese, and lemmings of Wrangel Island in summer

A study on Wrangel Island reveals significant dietary overlap among ruminants, geese, and lemmings during summer, indicating resource partitioning where weaker competitors follow stronger ones. The research suggests that prior to the establishment of a nature reserve, human activities influenced the dynamics of this Arctic herbivore community. The findings highlight how competitive advantages, such as a broad food spectrum, shape community structure in insular ecosystems.
