  1. 1. Palaeoenvironmental changes in the northern boreal zone of Finland: local versus regional drivers

    Author : Shyhrete Shala; Karin H. Helmens; Christian Bigler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeolimnology; Palaeoecology; Biological assemblages; Sediment geochemistry; Regional drivers; Local drivers; Quantitative temperature reconstructions; Transfer-functions; Holocene; MIS 5d-c; Northern boreal zone; NE Finland; kvartärgeologi; Quaternary Geology;

    Abstract : Multiple proxies derived from the Lake Loitsana sediment sequence (NE Finland) are employed to determine the timing of deglaciation, characterise an early Holocene proglacial lake stage and reconstruct Holocene lake development. Local-scale processes causing shifts in biological assemblages are identified and the most likely Holocene mean July air temperature (Tjul) development is assessed. READ MORE

  2. 2. Multiple forces drive the Baltic Sea food web dynamics and its response to environmental change

    Author : Susa Niiranen; Thorsten Blenckner; Olle Hjerne; Mike Elliott; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; climate change; Ecopath with Ecosim; food web interactions; multiple drivers; regime shift; trophic control; Marine Ecology; marin ekologi;

    Abstract : Understanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world’s seas most strongly impacted by effects from both human activities and climate. READ MORE

  3. 3. The Impact of Multiple Drivers on Marine Systems : Novel approaches for studying structural changes

    Author : Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturresurshushållning; Natural Resources Management;

    Abstract : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. READ MORE

  4. 4. Model for change in production systems triggered by environmental requirements : considerations, drivers, key factors

    Author : Anna Sannö; Mats Deleryd; Mats Winroth; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change management; environment; sustainable development; Innovation and Design; innovation och design;

    Abstract : Industry is a key player in the transition to a sustainable society where manufacturing companies need to respond to the challenges of environmental concerns in several ways. Still, even if several efforts have been made in practise and academia, more research within operations management is addressed in relation to implementing sustainable solutions. READ MORE

  5. 5. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

    Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

    Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.
