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, ...


Impact of food and predation on the snowshoe hare cycle

Science, Vol. 269, No. 5227. (25 August 1995), pp. 1112-1115,


Snowshoe hare populations in the boreal forests of North America go through 10-year cycles. Supplemental food and mammalian predator abundance were manipulated in a factorial design on 1-square-kilometer areas for 8 years in the Yukon. Two blocks of forest were fertilized to test for nutrient effects. Predator exclosure doubled and food addition tripled hare density during the cyclic peak and decline. Predator exclosure combined with food addition increased density 11-fold. Added nutrients increased plant growth but not hare density. Food and ...

Effects of differential habitat warming on complex communities

Proceedings of the National Academy of Sciences, Vol. 111, No. 22. (03 June 2014), pp. 8077-8082,


[Significance] Organisms may adjust their behavior to stay cool as natural habitats differentially warm with rising air temperature. Undoubtedly, fundamental ecosystem properties will change in turn, but the impact of the dynamic thermal mosaic on food web interactions is not considered in traditional climate change research. To demonstrate differential warming effects on food webs, we use boreal lakes to show that the energy pathways leading to an apex predator shift, according to thermal preference, and the vertical pathway lengthened in warmer ...


Reply to Feeley and Machovina: trophic ecology complements estimates of land use change due to food production

Proceedings of the National Academy of Sciences, Vol. 111, No. 9. (04 March 2014), pp. E795-E795,


[Excerpt] Feeley and Machovina assert that even though humans occupy a low trophic level, we have larger ecosystem impacts than any other species because of the sheer volume of food consumed (linked to population size) and the inefficiency of its production (1). The authors argue that large differences in the impact on resource use exist between dietary preferences (e.g., differing proportions of beef, pork, or poultry in a diet), even if human diets are represented by the same trophic level. We are ...


Increasing preference for beef magnifies human impact on world’s food web

Proceedings of the National Academy of Sciences, Vol. 111, No. 9. (04 March 2014), pp. E794-E794,


Bonhommeau et al.’s report, “Eating up the world’s food web and the human trophic level” (1), provides a valuable perspective on the role of human food consumption within the global ecosystem. However, the ranking of human beings at a similar trophic level as other animals downplays the effects that humans have on the Earth in comparison with other species. The sheer volume of food consumed by humans and our growing preference for inefficient food sources cause us to have increasingly disproportionate ...


Soil food web properties explain ecosystem services across European land use systems

Proceedings of the National Academy of Sciences, Vol. 110, No. 35. (27 August 2013), pp. 14296-14301,


Intensive land use reduces the diversity and abundance of many soil biota, with consequences for the processes that they govern and the ecosystem services that these processes underpin. Relationships between soil biota and ecosystem processes have mostly been found in laboratory experiments and rarely are found in the field. Here, we quantified, across four countries of contrasting climatic and soil conditions in Europe, how differences in soil food web composition resulting from land use systems (intensive wheat rotation, extensive rotation, and ...

Meta-information Database (INRMM-MiD).
This database integrates a dedicated meta-information database in CiteULike (the CiteULike INRMM Group) with the meta-information available in Google Scholar, CrossRef and DataCite. The Altmetric database with Article-Level Metrics is also harvested. Part of the provided semantic content (machine-readable) is made even human-readable thanks to the DCMI Dublin Core viewer. Digital preservation of the meta-information indexed within the INRMM-MiD publication records is implemented thanks to the Internet Archive.
