How do human communities integrate within food webs? Studies characterizing the historical flow of energy among people and local environments can yield important insights into managing sustainable ecosystems. Here, we combine zooarchaeological, bulk tissue, compound-specific stable isotope data from late Holocene Santa Rosa Island to investigate ecological role a southern California nearshore marine ecosystem. We show foraged in diverse habitats, including kelp forests pelagic waters, consumed wide range species. However, zooarchaeological results reveal >50% recovered fish remains came presumed forest carnivores mid-trophic level (3.0–4.0) such as surfperches rockfishes. Local fishing strategies thus did not involve preferential removal large-bodied, high trophic species – pattern known “fishing down web” which has been documented modern commercial fisheries collapse Essential amino acid δ 13 C analysis revealed that community relied on basal resources kelps phytoplankton. This coupling benthic sources suggests coastal webs region were relatively configuration immediately prior first European arrival. stability likely contributed sustaining densely populated Chumash settlements, intensive fisheries, faunal diversity. Our findings provide pre-industrial for ecosystems document some mechanisms behind intensive, yet long-term Chumash.

Historical ecology has revolutionized our understanding of fisheries and cultural landscapes, demonstrating the value historical data for evaluating past, present, future Earth's ecosystems. Despite several important studies, Indigenous generally receive less attention from scholars managers than 17th-20th century capitalist commercial that decimated many keystone species, including oysters. We investigate oyster harvest through time in North America Australia, placing these context sea level histories catch records. were pervasive across space time, persisting 5000-10,000 years or more. Oysters likely managed sometimes "farmed," are woven into broader cultural, ritual, social traditions.

How can the disintegration of ecosystems, foundation life on Earth, be halted and these critical systems rehabilitated? For scholars, action list is long: increase pool expertise by engaging all relevant knowledge communities, collect rapidly disappearing data, analyze with both familiar new methods, apply results actionable science to policy practice. This enormously complex urgent activity requires an integrated research framework flexibility accommodate global diversity places, peoples, processes examine future options. Based evidence environmental change human activity, termed historical ecology assembles tools construct evidence-validated, open-ended narrative evolution transformation specific ecosystems landscapes. Welcoming from scholars communities heritage practice, this comprehensive systemic understanding offers insights, models, ideas for durable contemporary The article evaluates how practitioners could adjust aspects practice improve access makers, discussion applies regions localities everywhere.

Cultural land-use is an important driver of ecosystem change, influencing the composition species across landscapes and through time. Recent research in northwestern North America has shown that historical Indigenous forest management resulted relict gardens dominated by edible fruit, nut, berry producing trees shrubs – many which continue to grow adjacent archaeological village sites today.

Coastal social-ecological systems are vulnerable to climate change with impacts distributed unequally amongst human communities. Vulnerability assessments, an increasingly popular methodology for understanding variability in vulnerability and its components, often fail include or recognize the perceptions of individuals focal system. Perceptions influenced by experiences, social networks, cognitive biases, differ from as measured subject experts. Because influence behavior, including if how people take adaptive action, a failure can lead ineffective adaptation plans incomplete system vulnerability.

Historical ecology draws on a broad range of information sources and methods to provide insight into ecological social change, especially over the past ∼12000 yr. While its results are often relevant conservation restoration, insights from diverse disciplines, environments, geographies have frequently remained siloed or underrepresented, restricting their full potential. Here, scholars practitioners working in marine, freshwater, terrestrial environments 6 continents various archipelagoes synthesize knowledge fields history, anthropology, paleontology, with goal describing global research priorities for historical influence conservation. We used structured decision-making process identify address questions 4 key priority areas: (1) concepts, (2) co-production community engagement, (3) policy management, (4) climate change impacts. This work highlights ways that has developed matured use novel sources, efforts move beyond extractive practices toward co-production, application management challenges including change. demonstrate this field brought together researchers across connected academics practitioners, engaged communities create apply our shared future.

Abstract Since the 19th century, study of shell middens has played an important role in archaeological research. Shell midden and broader coastal archaeology have transformed our understanding human relationships with aquatic habitats, demonstrating importance marine environments to evolution ecology, colonization islands establishment maritime trade networks, changing social political dynamics, a variety other issues. During past two decades, research greatly increased, marking exciting time for new discoveries heightened collaboration Indigenous communities. Several key trends during 10–15 years include on site distribution temporality, underwater archaeology, historical terraforming, landscape legacies, community collaboration. These demonstrate ways which archaeologists are shaping environmental change around world.
