The maritime fur trade (1785–1840s) led to the local extinction of sea otters (Enhydra lutris) in many parts of the northeast Pacific. On the basis of studies of extant sea otter populations, it has been established that they have a disproportionate effect on nearshore ecosystems by limiting sea urchin abundance and facilitating the establishment of nearshore kelp forests; in the absence of sea otters, a local reduction in kelp-derived carbon is therefore expected. We measured the isotopic… 

Back to the future? Late Holocene marine food web structure in a warm climatic phase as a predictor of trophodynamics in a warmer South‐Western Atlantic Ocean

A declining pattern of marine primary productivity during the Late Holocene in the Beagle Channel was confirmed and all the species that have undergone intense human exploitation significantly increased their trophic levels, highlighting the relevance of using zooarchaeological remains for providing predictions about marine food webs changes in the near future.

Ancient DNA analysis of Indigenous rockfish use on the Pacific Coast: Implications for marine conservation areas and fisheries management

It is demonstrated that ancient DNA identifications of archaeological assemblages can complement and expand perspective on modern day fisheries conservation and management in this National Park Reserve and First Nations ancestral territory.

Long‐term ecological changes in marine mammals driven by recent warming in northwestern Alaska

Significant and dramatic changes in ringed seal stable isotope values between the early 19th and early 21st centuries are observed, likely due to changing sea ice productivity and reduced delivery of organic matter to the benthos driven by recent warming in the Arctic.

Archaeological data provide alternative hypotheses on Pacific herring (Clupea pallasii) distribution, abundance, and variability

Assessment of fish bones from 171 archaeological sites from Alaska, British Columbia, and Washington to provide proxy measures of past herring distribution and abundance reveals that herring exhibits consistently high abundance and consistently low variance within the majority of sites, which can inform modern management.

Restructuring of nutrient flows in island ecosystems following human colonization evidenced by isotopic analysis of commensal rats

The results highlight the large-scale restructuring of nutrient flows in island ecosystems that resulted from human colonization and ecosystem engineering activities on Pacific islands and demonstrate that stable isotope analysis of often-ignored commensal taxa can provide a tool for tracking human land use and environmental effects.

What ancient DNA reveals about the ubiquitous rockfish of the Pacific Coast of North America

Approximately 100 rockfish species are found in the North Pacific Ocean (Orr and Hawkins 2008), and typically these can only be identified archaeologically to the genus level, Sebastes . Recent

Ecological consequences of human niche construction: Examining long-term anthropogenic shaping of global species distributions

This work focuses on four major phases that witnessed broad anthropogenic alterations to biodiversity—the Late Pleistocene global human expansion, the Neolithic spread of agriculture, the era of island colonization, and the emergence of early urbanized societies and commercial networks.


Historical zooarchaeologists have made significant contributions to key questions about the social, economic, and nutritional dimensions of domestic animal use in North American colonial contexts;



Changes in northeast Pacific marine ecosystems over the last 4500 years: evidence from stable isotope analysis of bone collagen from archeological middens

Changes in food web dynamics and ocean productivity over the past 4500 years are investigated using stable isotope analysis of nitrogen and carbon in collagen from animal bones preserved in coastal

Biogeographic and nearshore-offshore trends in isotope ratios of intertidal mussels and their food sources around the coast of southern Africa

There are broad differences in oceanography and primary production around the south- ern African coast that are likely to give rise to major differences in trophic pathways. Stable isotope ratios

Historical Ecology and Biogeography of North Pacific Pinnipeds: Isotopes and Ancient DNA from Three Archaeological Assemblages

ABSTRACT Zooarchaeology has the potential to make significant contributions to knowledge of pinniped biogeography of import to both archaeologists and environmental scientists. We analyzed northern

Kelp and rivers subsidize rocky intertidal communities in the Pacific Northwest (USA).

It is shown that filter feeder trophic positions were higher in winter when river discharge is highest, near river mouths where river-borne inputs are highest, and downstream of more heavily logged watersheds where river loads of dissolved organic carbon are highest.

Indirect food web interactions: sea otters and kelp forest fishes in the Aleutian archipelago

The overexploitation, recovery and subsequent collapse of sea otter populations in the Aleutian archipelago is used to explore if and how the abundance and diet of kelp forest fishes are influenced by a trophic cascade linking sea otters with sea urchins and fleshy macroalgae.

Stability, resilience, and phase shifts in rocky subtidal communities along the west coast of Vancouver Island, Canada

We used the extirpation, reintroduction, and spread of sea otters (Enhydra lutris) along the west coast of Vancouver Island, Canada, to evaluate how the otter–urchin–algae trophic cascade creates

Cascading effects of fishing can alter carbon flow through a temperate coastal ecosystem.

The effects of fishing on nearshore trophic structure and carbon flux are context-dependent and hinge on large-scale, regional oceanographic factors, indicating that overfishing can have profound consequences on ecosystem functioning particularly where pelagic primary production is limiting.

Trophic relationships and isotopic gradients among arctic and subarctic marine fauna

Geographic gradients in the isotopic composition of marine zooplankton provide natural markers valuable for tracing migrational patterns and feeding habits of their predators and have contributed significantly to understanding the natural history of this animal.
