  1. 1. Production in a State of Abundance : Valuation and Practice in the Swedish Meat Supply Chain

    Author : Jonas Bååth; Patrik Aspers; Tora Holmberg; Turo-Kimmo Lehtonen; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abundance; production; valuation; Swedish meat industry; supply chain; post-scarcity society; economic sociology; food studies; agriculture; grocery retail; pragmatism; practice theory; ethnography; Sociologi; Sociology;

    Abstract : This thesis is a sociological contribution to the study of abundance. It discusses the case of Swedish meat producers and how they persist in producing pork and beef despite a lack of demand and competitive disadvantages compared with foreign suppliers. READ MORE

  2. 2. Scarcity, Abundance and Sufficiency: Contributions to Social and Economic Theory

    Author : Adel Daoud; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : economics; sociology; scarcity; abundance; sufficiency;

    Abstract : Economic sociology has established itself as a strong and vibrant field in the social sciences. A number of significant studies have been conducted on the relation between the economy and society: on firms, markets, networks, money, and general action theory. But little has been done on the issues of scarcity, abundance, and sufficiency (SAS). READ MORE

  3. 3. Direct and indirect effects of fish predation and excretion in aquatic food webs

    Author : José Luiz Attayde; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; marine biology; Hydrobiology; zooplankton; resilience; predation; phytoplankton; nutrient enrichment; nutrient recycling; interaction strength; herbivory; food webs; food chain; excretion; fish; detritus; detritivory; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Ecology; Ekologi;

    Abstract : The aim of this thesis was to elucidate the mechanisms by which planktivorous fish can affect planktonic communities in lakes and how they may affect benthic communities through their effects on planktonic communities. In a laboratory experiment, nutrients released by fish increased algal biomass and altered phytoplankton community structure, suggesting that fish can affect phytoplankton by directly releasing nutrients.

  4. 4. The role of terrestrial and phytoplankton-derived organic matter in planktonic food webs

    Author : Anja Wenzel; Ann-Kristin Bergström; Tobias Vrede; Maarten Boersma; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Daphnia; phytoplankton; heterotrophic bacteria; terrestrial particulate organic material; food quality; food quantity; fatty acids; oligotrophic; Light:Nutrient-Hypothesis; limnologi; Limnology;

    Abstract : Lakes are important global ecosystems and many of them are nutrient-poor (unproductive). Especially in northern boreal latitudes, lakes may be heavily subsidized by terrestrial organic material (t-OM) from peat layers in the catchment. READ MORE

  5. 5. Pelagic microorganisms in the northern Baltic Sea : Ecology, diversity and food web dynamics

    Author : Johnny Berglund; Agneta Andersson; Ramon Massana; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; resource limitation; predation limitation; microbial food web; heterotrophic microorganisms; nanoflagellates; ciliates; protists; resource heterogeneity; chrysomonads; chrysophytes; group-specific PCR-DGGE primers; Baltic Sea; Marine ecology; Marin ekologi;

    Abstract : Heterotrophic microorganisms are important for the flow of carbon and nutrients in the sea. Bacteria, nanoflagellates and ciliates are relevant components of the pelagic food web. In order to be able to predict the outcome of e.g. READ MORE
