Defining the Anthropocene on California's Northern Channel Islands (2017)
DOCUMENT Citation Only Jon Erlandson. Todd Braje. Kristina Gill. Torben Rick.

California's Northern Channel Islands provide some of the most detailed and well-preserved records of human occupation of dynamic island landscapes in the world. Here, archaeological and historical ecological research over the past 20 years has produced a variety of data about human eco-dynamics in both terrestrial and marine ecosystems, spanning nearly 13,000 years. We summarize current knowledge of cultural and ecological changes from Paleoindian to historic times, focusing on what...


Human and Environmental Histories of the Rat Islands, Western Aleutians, Alaska: The 2014-2015 Research Season (2015)
DOCUMENT Citation Only Caroline Funk. Nancy Bigelow. Debra Corbett. Brian Hoffman. Nicole Misarti.

Our multidisciplinary research team is beginning to model the role of humans in shaping the characteristics of existing southern Bering Sea and North Pacific terrestrial and marine ecologies in the Western Aleutians. During this past research season, we defined new cultural loci, acquired on and off-site pollen/tephra cores, and surveyed the coastal zone on areas of Kiska, Segula, and Little Sitkin Islands. The cultural occupations span Aleut prehistory and the World War II Japanese occupation....


Measuring Human Impacts on Islands Relative to Size (2017)
DOCUMENT Citation Only John O'Connor. Scott Fitzpatrick. Todd Braje. Matthew Napolitano. Thomas Leppard.

Archaeological research on islands worldwide demonstrates that initial colonists exerted substantial environmental impacts on local ecologies, ranging from the extirpation of native species to landscape modification. The degree of impact was dependent on a host of variables, including the kinds and number of introduced plant and animal species, the remoteness of settled islands, and extent of interaction between discrete landmasses. Yet, there is still much to learn about the consequences of...
