  2. 1. Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique

    Author : Daniela de Abreu; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tropics; Southeast Africa; Shallow water; Estuaries; Nursery ground value; Decapods; Penaeidae; Carbon and nitrogen isotopes; Diet; Acetyl cholinesterase; Butyryl cholinesterase; Metals;

    Abstract : Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most important fishery resources worldwide, and in Mozambique they are the basis of a profitable commercial fishery, landing hundreds of tons per year. READ MORE

  4. 2. Mineralisation rates of natural organic matter in surface sediments affected by physical forces

    Author : Carina Ståhlberg; Bo Svensson; Lars Rahm; David Bastviken; Anders Tengberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment; Organic matter mineralisation; Organic matter degradation; Redox; Electron acceptor; Resuspension; Advective pore water flow; Other chemistry; Övrig kemi;

    Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE

  5. 3. Tracking environmental changes of the Baltic Sea coastal zone since mid-Holocene

    Author : Wenxin Ning; Centrum för miljö- och klimatvetenskap (CEC); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, I used two coastal sediment sequences from SE Sweden to study how Baltic Sea coastal environment has changed since the mid-Holocene. The results show the coastal environment has been influenced by multi-stressors, such as climate change, shoreline regression and anthropogenic activities. READ MORE

  6. 4. Palaeoenvironments, palaeoecology and palaeobiogeography of Late Cretaceous (Campanian) faunas from the Kristianstad Basin, southern Sweden, with applications for science education
