Biomass production, supply, uses and flows in the European Union - First results from an integrated assessment

Vol. 28993 EN (2018),


[Executive summary] This report illustrates part of the results from the first two years of JRC biomass study, carried out in the context of the mandate on the provision to EC services of data and analysis on biomass flow, supply and demand on a long-term basis. [\n] The JRC biomass study has a wide scope and is a long-term endeavour, not having a pre-defined duration. Here we refer to the results after the first two years, with a focus on the assessments of ...


Economic value of ecological information in ecosystem-based natural resource management depends on exploitation history

Proceedings of the National Academy of Sciences, Vol. 115, No. 7. (13 February 2018), pp. 1658-1663,


[Significance] Natural resource management is evolving toward a more holistic approach that acknowledges ecological connections among species. To date, there has been no demonstration of where or when this approach provides economic benefits. Here we find only modest economic benefits from having detailed knowledge of ecological linkages between species. However, the costs of incomplete or incorrect knowledge are unevenly distributed across user groups and are greater after historical overfishing. The ecosystem approach to natural resource management might therefore provide the greatest benefit ...


Regulation of lake primary productivity by food web structure

Ecology, Vol. 68, No. 6. (December 1987), pp. 1863-1876,


We performed whole—lake manipulations of fish populations to test the hypothesis that higher trophic levels regulate zooplankton and phytoplankton community structure, biomass, and primary productivity. The study involved three lakes and spanned 2 yr. Results demonstrated hierarchical control of primary production by abiotic factors and a trophic cascade involving fish predation. In Paul Lake, the reference lake, productivity varied from year to year, illustrating the effects of climatic factors and the natural dynamics of unmanipulated food web interactions. In Tuesday Lake, ...


Effects of fish in river food webs

Science, Vol. 250, No. 4982. (09 November 1990), pp. 811-814,


Experimental manipulations of fish in a Northern California river during summer base flow reveal that they have large effects on predators, herbivores, and plants in river food webs. California roach and juvenile steelhead consume predatory insects and fish fry, which feed on algivorous chironomid larvae. In the presence of fish, filamentous green algae are reduced to low, prostrate webs, infested with chironomids. When the absence of large fish releases smaller predators that suppress chironomids, algal biomass is higher, and tall upright ...


No saturation in the accumulation of alien species worldwide

Nature Communications, Vol. 8 (15 February 2017), 14435,


Although research on human-mediated exchanges of species has substantially intensified during the last centuries, we know surprisingly little about temporal dynamics of alien species accumulations across regions and taxa. Using a novel database of 45,813 first records of 16,926 established alien species, we show that the annual rate of first records worldwide has increased during the last 200 years, with 37% of all first records reported most recently (1970–2014). Inter-continental and inter-taxonomic variation can be largely attributed to the diaspora of ...


Passing the point of no return

Science, Vol. 354, No. 6316. (02 December 2016), pp. 1109-1109,


[Excerpt] In the field of ecology, regime shifts are massive changes in function and character that occur when an ecosystem passes a tipping point. Regime shifts sometimes have severe consequences for human well-being through losses of ecosystem services, including desertification in arid regions and marine fisheries collapses. These changes are difficult to predict and sometimes impossible to reverse. For these reasons, understanding how to anticipate and prevent regime shifts is one of the most important challenges faced by environmental scientists. [\n] Theoretical analyses ...


Dam-building threatens Mekong fisheries

Science, Vol. 354, No. 6316. (02 December 2016), pp. 1084-1085,


[Excerpt] Every April, the pa nyawn catfish would make their way up the Mekong River to spawn, crowding through a narrow channel that skirts Khone Falls in southern Laos. Villagers netted the thumb-sized fish by the hundreds of thousands. Then, in 2014, work started on Don Sahong Dam, which straddles the channel. Although the dam won't be completed for another 2 years, construction has already cut off the migration and destroyed the fishing sites, says Zeb Hogan, a biologist with the ...


The development of environmental thinking in economics

Environmental Values, Vol. 8, No. 4. (November 1999), pp. 413-435,


There has always been a sub-group of established economists trying to convey an environmental critique of the mainstream. This paper traces their thinking into the late 20th century via the development of associations and journals in the USA and Europe. There is clearly a divergence between the conformity to neo-classical economics favoured by resource and environmental economists and the acceptance of more radical critiques apparent in ecological economics. Thus, the progressive elements of ecological economics are increasingly incompatible with those practising ...


A horizon scan of global conservation issues for 2016

Trends in Ecology & Evolution, Vol. 31, No. 1. (January 2016), pp. 44-53,


This paper presents the results of our seventh annual horizon scan, in which we aimed to identify issues that could have substantial effects on global biological diversity in the future, but are not currently widely well known or understood within the conservation community. Fifteen issues were identified by a team that included researchers, practitioners, professional horizon scanners, and journalists. The topics include use of managed bees as transporters of biological control agents, artificial superintelligence, electric pulse trawling, testosterone in the aquatic ...

Ecosystem-based fishery management

Science, Vol. 305, No. 5682. (2004), pp. 346-347,


[Summary] Ecosystem-based fishery management (EBFM) is a new direction for fishery management, essentially reversing the order of management priorities so that management starts with the ecosystem rather than a target species. EBFM aims to sustain healthy marine ecosystems and the fisheries they support. Pikitch et al. describe the potential benefits of implementation of EBFM that, in their view, far outweigh the difficulties of making the transition from a management system based on maximizing individual species. ...


Historical overfishing and the recent collapse of coastal ecosystems

Science, Vol. 293, No. 5530. (2001), pp. 629-637,


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 ...


Reconsidering the consequences of selective fisheries

Science, Vol. 335, No. 6072. (2012), pp. 1045-1047,

Impacts of fishing low - Trophic level species on marine ecosystems

Science, Vol. 333, No. 6046. (2011), pp. 1147-1150,


Low–trophic level species account for more than 30% of global fisheries production and contribute substantially to global food security. We used a range of ecosystem models to explore the effects of fishing low–trophic level species on marine ecosystems, including marine mammals and seabirds, and on other commercially important species. In five well-studied ecosystems, we found that fishing these species at conventional maximum sustainable yield (MSY) levels can have large impacts on other parts of the ecosystem, particularly when they constitute a ...


Status and solutions for the world's unassessed fisheries

Science, Vol. 338, No. 6106. (2012), pp. 517-520,


Recent reports suggest that many well-assessed fisheries in developed countries are moving toward sustainability. We examined whether the same conclusion holds for fisheries lacking formal assessment, which comprise >80% of global catch. We developed a method using species’ life-history, catch, and fishery development data to estimate the status of thousands of unassessed fisheries worldwide. We found that small unassessed fisheries are in substantially worse condition than assessed fisheries, but that large unassessed fisheries may be performing nearly as well as their ...


Extinction, Substitution, and Ecosystem Services

BioScience, Vol. 33, No. 4. (01 April 1983), pp. 248-254,


The loss of services to humanity following extinctions ranges from trivial to catastrophic, depending on the number of elements (populations, species, guilds) deleted and the degree of control each exerted in the system. Most attempts to substitute other organisms for those lost have been unsuccessful, to one degree or another, and prospects for increasing the success rate in the foreseeable future are not great. Attempts to supply the lost services by other means tend to be expensive failures in the long ...


In new report, IPCC gets more specific about warming risks

Science, Vol. 344, No. 6179. (4 April 2014), pp. 21-21,


The Intergovernmental Panel on Climate Change's (IPCC's) 31 March report on climate impacts and adaptation echoes many of the concerns raised by the last edition, issued in 2007. It says that climate change is already affecting human communities, agriculture, and natural ecosystems—and impacts are likely to grow in the future. But the report breaks with the past in drawing on an emerging body of social science to identify eight major risks posed by climate change, and to inform an extensive discussion ...


Fish parasites resolve the paradox of missing coextinctions

Nature Communications, Vol. 4 (16 April 2013), 1718,


Models of coextinction identify parasites as one of the most menaced ecological groups. The number of host species a parasite uses should strongly affect its risk of coextinction. The naïve expectation is that the lower the number, the higher is the parasite’s risk of being left with no hosts. Here we analyse the coextinction risk of 12,141 fish parasite species and find that highly specific parasites are not the most endangered, because they tend to use hosts with low vulnerability to ...
