We combine data collected from the past 40 years to estimate the indirect effects of sea otters (Enhydra lutris) on ecosystem carbon (C) production and storage across their North American range, from Vancouver Island to the western edge of Alaska's Aleutian Islands. [] Key Result We find that sea otters, by suppressing sea urchin (Strongylocentrotus spp) populations, allow kelp (Order Laminariales) ecosystems to develop with a net primary productivity (NPP) of 313–900 grams C per square meter per year (g C m…

From the predictable to the unexpected: kelp forest and benthic invertebrate community dynamics following decades of sea otter expansion

The findings suggest that initial nearshore community responses to sea otter population expansion follow predictably from trophic cascade theory, but now, other factors may be as or more important in influencing community dynamics.

Effects of gray wolf‐induced trophic cascades on ecosystem carbon cycling

It is predicted that predator-induced trophic cascades could have important impacts on ecosystem carbon cycling. Yet the magnitude and direction of predator impacts on carbon cycling have not been

Environmental factors influencing primary productivity of the forest-forming kelp Laminaria hyperborea in the northeast Atlantic

Net primary productivity indicated that L. hyperborea forests are highly productive, but given the strong links with temperature, continued ocean warming in the northeast Atlantic may reduce primary productivity of this foundation species, as optimal temperatures for growth and performance are surpassed.

Southeast Alaskan kelp forests: inferences of process from large-scale patterns of variation in space and time

How small-scale variability in otter occupancy, ostensibly due to spatial variability in harvesting or the risk landscape for otters, can result in within-region patchiness in these community states is highlighted.

Consumer regulation of the carbon cycle in coastal wetland ecosystems

Despite escalating anthropogenic alteration of food webs, how the carbon cycle in ecosystems is regulated by food web processes remains poorly understood. We quantitatively synthesize the effects of

Marine deforestation leads to widespread loss of ecosystem function

The effects of deforestation on ecosystem productivity were highly variable between years and among the study islands, suggesting that marine deforestation profoundly affects how coastal ecosystems function.

Trophic cascade alters ecosystem carbon exchange

By manipulating the presence of herbivores and predators, it is shown that even without an initial change in total plant or herbivore biomass, the cascading effects of predators in this system begin to affect carbon cycling through enhanced carbon fixation by plants.

Reductions in the dietary niche of southern sea otters (Enhydra lutris nereis) from the Holocene to the Anthropocene

The ecological niche of ancient southern sea otters using δ13C analysis and δ15N analysis of bones recovered from archaeological sites at five regions along the coast of California finds ancient otters occupied a larger isotopic niche than nearly all modern localities; likely reflecting broader habitat and prey use in prefur trade populations.

Predator effects link ecological communities: kelp created by sea otters provides an unexpected subsidy to bald eagles

. Ecological communities are best studied at the landscape level, where linkages among communities are considered. Such linkages are often driven by increases in primary production caused by apex



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.

Sea Otters and Kelp Forests in Alaska: Generality and Variation in a Community Ecological Paradigm

Analysis of generality of a three-trophic-level cascade among sea otters, invertebrate herbivores, and macroalgae in Alaska demonstrates that sea otter predation has a predictable and broadly generalizable influence on the structure of Alaskan kelp forests.

Promotion of ecosystem carbon sequestration by invasive predators

Despite recent interest in understanding the effects of human-induced global change on carbon (C) storage in terrestrial ecosystems, most studies have overlooked the influence of a major element of

Food Availability, Sea Urchin Grazing, and Kelp Forest Community Structure

A qualitative model in which the transformation from one configuration to another is triggered by a behavioral switch in the mode of feeding of red sea urchins is presented, which provides a new view of how kelp forest communities function.

Organic enrichment of submarine‐canyon and continental‐shelf benthic communities by macroalgal drift imported from nearshore kelp forests

Remotely operated vehicle (ROV) surveys were conducted over a 3‐year period to evaluate the importance of macroalgal drift exported from nearshore forests of giant kelp (Macrocystis pyrifera) to

Rockfish recruitment and trophic dynamics on the west coast of Vancouver Island : fishing, ocean climate, and sea otters

This dissertation describes three studies in which it is found that although growth rates of both rockfish groups responded positively to ocean temperature, the highest recruitment success over a six-year period corresponded to strong and prolonged upwelling that favored onshore transportation of pelagic larvae, but not pre-settlement growth and survival.

Partitioning of primary production among giant kelp (Macrocystis pyrifera), understory macroalgae, and phytoplankton on a temperate reef

Surprisingly, total ecosystem production that included NPP by macroalgae, phytoplankton, and understory algae did not differ between the Macrocystis control and removal plots for much of the study.

A cross-ecosystem comparison of the strength of trophic cascades

Although trophic cascades (indirect effects of predators on plants via herbivores) occur in a wide variety of food webs, the magnitudes of their effects are often quite variable. We compared the

Abstract We estimated carrying capacity for sea otters (Enhydra lutris) in the coastal waters of British Columbia, Canada, by characterizing habitat according to the complexity of nearshore
