    Historical overfishing and the recent collapse of coastal ecosystems (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-07-28
    Description: Ecological extinction caused by overfishing precedes all other pervasive human disturbance to coastal ecosystems, including pollution, degradation of water quality, and anthropogenic climate change. Historical abundances of large consumer species were fantastically large in comparison with recent observations. Paleoecological, archaeological, and historical data show that time lags of decades to centuries occurred between the onset of overfishing and consequent changes in ecological communities, because unfished species of similar trophic level assumed the ecological roles of overfished species until they too were overfished or died of epidemic diseases related to overcrowding. Retrospective data not only help to clarify underlying causes and rates of ecological change, but they also demonstrate achievable goals for restoration and management of coastal ecosystems that could not even be contemplated based on the limited perspective of recent observations alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jackson, J B -- Kirby, M X -- Berger, W H -- Bjorndal, K A -- Botsford, L W -- Bourque, B J -- Bradbury, R H -- Cooke, R -- Erlandson, J -- Estes, J A -- Hughes, T P -- Kidwell, S -- Lange, C B -- Lenihan, H S -- Pandolfi, J M -- Peterson, C H -- Steneck, R S -- Tegner, M J -- Warner, R R -- New York, N.Y. -- Science. 2001 Jul 27;293(5530):629-37.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Scripps Institution of Oceanography, University of California, San Diego, La Jolla, CA 92093-0244, USA. jbcj@ucsd.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11474098" target="_blank"〉PubMed〈/a〉

    Killer whale predation on sea otters linking oceanic and nearshore ecosystems (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-10-17
    Description: After nearly a century of recovery from overhunting, sea otter populations are in abrupt decline over large areas of western Alaska. Increased killer whale predation is the likely cause of these declines. Elevated sea urchin density and the consequent deforestation of kelp beds in the nearshore community demonstrate that the otter's keystone role has been reduced or eliminated. This chain of interactions was probably initiated by anthropogenic changes in the offshore oceanic ecosystem.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Estes -- Tinker -- Williams -- Doak -- New York, N.Y. -- Science. 1998 Oct 16;282(5388):473-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9774274" target="_blank"〉PubMed〈/a〉

    Trophic downgrading of planet Earth (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-19
    Description: Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind's most pervasive influence on nature. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine, terrestrial, and freshwater ecosystems worldwide. This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles. These findings emphasize the urgent need for interdisciplinary research to forecast the effects of trophic downgrading on process, function, and resilience in global ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Estes, James A -- Terborgh, John -- Brashares, Justin S -- Power, Mary E -- Berger, Joel -- Bond, William J -- Carpenter, Stephen R -- Essington, Timothy E -- Holt, Robert D -- Jackson, Jeremy B C -- Marquis, Robert J -- Oksanen, Lauri -- Oksanen, Tarja -- Paine, Robert T -- Pikitch, Ellen K -- Ripple, William J -- Sandin, Stuart A -- Scheffer, Marten -- Schoener, Thomas W -- Shurin, Jonathan B -- Sinclair, Anthony R E -- Soule, Michael E -- Virtanen, Risto -- Wardle, David A -- New York, N.Y. -- Science. 2011 Jul 15;333(6040):301-6. doi: 10.1126/science.1205106.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95060, USA. jestes@ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21764740" target="_blank"〉PubMed〈/a〉

    Introduced predators transform subarctic islands from grassland to tundra (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-26
    Description: Top predators often have powerful direct effects on prey populations, but whether these direct effects propagate to the base of terrestrial food webs is debated. There are few examples of trophic cascades strong enough to alter the abundance and composition of entire plant communities. We show that the introduction of arctic foxes (Alopex lagopus) to the Aleutian archipelago induced strong shifts in plant productivity and community structure via a previously unknown pathway. By preying on seabirds, foxes reduced nutrient transport from ocean to land, affecting soil fertility and transforming grasslands to dwarf shrub/forb-dominated ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croll, D A -- Maron, J L -- Estes, J A -- Danner, E M -- Byrd, G V -- New York, N.Y. -- Science. 2005 Mar 25;307(5717):1959-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Island Conservation, University of California-Santa Cruz, Santa Cruz, CA 95060, USA. croll@biology.ucsc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15790855" target="_blank"〉PubMed〈/a〉

    Magnification of secondary production by kelp detritus in coastal marine ecosystems (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-07-14
    Description: Kelps are highly productive seaweeds found along most temperate latitude coastlines, but the fate and importance of kelp production to nearshore ecosystems are largely unknown. The trophic role of kelp-derived carbon in a wide range of marine organisms was assessed by a natural experiment. Growth rates of benthic suspension feeders were greatly increased in the presence of organic detritus (particulate and dissolved) originating from large benthic seaweeds (kelps). Stable carbon isotope analysis confirmed that kelp-derived carbon is found throughout the nearshore food web.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duggins, D O -- Simenstad, C A -- Estes, J A -- New York, N.Y. -- Science. 1989 Jul 14;245(4914):170-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17787876" target="_blank"〉PubMed〈/a〉

    Status and ecological effects of the world's largest carnivores (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-01-11
    Description: Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores have substantial effects on the structure and function of diverse ecosystems. Significant cascading trophic interactions, mediated by their prey or sympatric mesopredators, arise when some of these carnivores are extirpated from or repatriated to ecosystems. Unexpected effects of trophic cascades on various taxa and processes include changes to bird, mammal, invertebrate, and herpetofauna abundance or richness; subsidies to scavengers; altered disease dynamics; carbon sequestration; modified stream morphology; and crop damage. Promoting tolerance and coexistence with large carnivores is a crucial societal challenge that will ultimately determine the fate of Earth's largest carnivores and all that depends upon them, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ripple, William J -- Estes, James A -- Beschta, Robert L -- Wilmers, Christopher C -- Ritchie, Euan G -- Hebblewhite, Mark -- Berger, Joel -- Elmhagen, Bodil -- Letnic, Mike -- Nelson, Michael P -- Schmitz, Oswald J -- Smith, Douglas W -- Wallach, Arian D -- Wirsing, Aaron J -- New York, N.Y. -- Science. 2014 Jan 10;343(6167):1241484. doi: 10.1126/science.1241484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Trophic Cascades Program, Department of Forest Ecosystems and Society, Oregon State University, Corvallis, OR 97331, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24408439" target="_blank"〉PubMed〈/a〉

    Marine defaunation: animal loss in the global ocean (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-01-17
    Description: Marine defaunation, or human-caused animal loss in the oceans, emerged forcefully only hundreds of years ago, whereas terrestrial defaunation has been occurring far longer. Though humans have caused few global marine extinctions, we have profoundly affected marine wildlife, altering the functioning and provisioning of services in every ocean. Current ocean trends, coupled with terrestrial defaunation lessons, suggest that marine defaunation rates will rapidly intensify as human use of the oceans industrializes. Though protected areas are a powerful tool to harness ocean productivity, especially when designed with future climate in mind, additional management strategies will be required. Overall, habitat degradation is likely to intensify as a major driver of marine wildlife loss. Proactive intervention can avert a marine defaunation disaster of the magnitude observed on land.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McCauley, Douglas J -- Pinsky, Malin L -- Palumbi, Stephen R -- Estes, James A -- Joyce, Francis H -- Warner, Robert R -- New York, N.Y. -- Science. 2015 Jan 16;347(6219):1255641. doi: 10.1126/science.1255641.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106, USA. douglas.mccauley@lifesci.ucsb.edu. ; Department of Ecology, Evolution, and Natural Resources, Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, NJ 08901, USA. ; Department of Biology, Stanford University, Hopkins Marine Station, Pacific Grove, CA 93950, USA. ; Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, CA 95060, USA. ; Department of Ecology, Evolution, and Marine Biology, University of California, Santa Barbara, CA 93106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25593191" target="_blank"〉PubMed〈/a〉

    Aleuts, sea otters, and alternate stable-state communities (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-04-28
    Description: Reexamination of stratified faunal components of a prehistoric Aleut midden excavated on Amchitka Island, Alaska, indicates that Aleut prey items changed dramatically during 2500 years of aboriginal occupation. Recent ecological studies in the Aleutian Islands have shown the concurrent existence of two alternate stable nearshore communities, one dominated by macroalgae, the other by epibenthic herbivores, which are respectively maintained by the presence or absence of dense sea otter populations. Thus, rather than cultural shifts in food preference, the changes in Aleut prey were probably the result of local overexploitation of sea otters by aboriginal Aleuts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simenstad, C A -- Estes, J A -- Kenyon, K W -- New York, N.Y. -- Science. 1978 Apr 28;200(4340):403-11.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17757287" target="_blank"〉PubMed〈/a〉
