Comparing harvestmen species composition between habitats on Nantucket Island, Massachusetts

Dataset submitted in fulfillment of a 2010 Nantucket Biodiversity Initiative grant.

From 2006 through 2008, we collected surface invertebrate specimens using pitfall traps from a variety of habitats on Nantucket Island and Tuckernuck Island, Massachusetts. In this project, we sorted 413 harvestmen from these samples, identified all specimens to species, and compared species distributions within four general habitat types. We identified all four species that appear on a historic species list from the late 1920’s and we added the non-native species Phalangium opilio. We found that H. maculosus prefers open heathland habitat over dense heathland and tupelo forest. Other species showed no significant preference for a specific habitat. We continue to sort specimens.
