    Effect of riparian structure, temperature and channel morphometry on detritus processing in channelized and natural woodland streams in southern Sweden1998In: Aquatic conservation, ISSN 1052-7613, E-ISSN 1099-0755, Vol. 8, no 2, p. 273-285Article in journal (Refereed)
    Abstract [en]

    1. Ten south Swedish streams were selected to represent two distinct types—natural woodland streams and channelized streams. Measurements were made on leaching, decomposition and microbial respiration of the dominant riparian vegetation (European Black Alder), structure of the benthic macroinvertebrate community, macroinvertebrates inhabiting leaf material, channel morphometry, macrophyte composition, water chemistry and total accumulated degree days.

    2. Leaf decomposition rates were not significantly different when channelized streams were compared with natural woodland streams. In channelized streams the average decomposition rate was −0.0556±0.0337 (±S.D.) day−1 compared with −0.0457±0.0115 day−1 in natural woodland streams.

    3. There was significantly higher variation in leaf decomposition among the five channelized streams compared with the five natural streams (F–test, p<0.05). This was mainly due to extremely high decomposition rates in channelized streams colonized by emergent macrophytes.

    4. Alder decomposition rates were low in channelized streams without macrophytes (−0.0053 °day−1), intermediate in natural streams (−0.0087 °day−1), and high in channelized streams with macrophytes (−0.0136 °day−1).

    5. The shredder functional group ranged from 13 to 70% of the benthic community in the natural streams. Channelized streams had a more variable shredder population ranging from 0.5 to 80%. The highest values were found in channelized streams that had become colonized by macrophytes.

    6. There was a significant difference in total accumulated degree days between the channelized (256 °day) and natural woodland streams (209 °day). This is most likely an effect of drainage tiles contributing warmer groundwater to the channelized streams during fall.

    7. It is concluded that, contrary to the prevailing conceptual model of stream systems, decomposition rates and macroinvertebrate functions are not necessarily reduced in streams without riparian vegetation. The loss of the riparian canopy can stimulate emergent macrophytes which will provide autochthonous detritus for benthic communities. This will change benthic community structure and the life cycle strategies present.

    Structure and function of buffer strips from a water-quality perspective in agricultural landscapes1995In: Landscape and Urban Planning, ISSN 0169-2046, E-ISSN 1872-6062, Vol. 31, no 1-3, p. 323-331Article in journal (Refereed)
    Abstract [en]

    Buffer strips can greatly improve the water quality of nearby agricultural streams by reducing nutrient leaching in groundwater and surface water runoff, even though they comprise little of the total catchment area. Hence, vegetated buffer zones located along streams and in the upland portions of the catchment can minimize erosion or trap sediments in surface runoff and thereby decrease phosphorus loading in surface water. For example, a buffer strip 10 m wide can reduce the phosphorus load, typically bound to sediment, by as much as 95%. Moreover, both natural and constructed riparian forests and wetlands may create conditions favorable for nitrogen transformation/removal by soil microbial processes such as denitrification, with as much as 100% of the nitrate being removed in these zones.

    In addition to nutrient removal, buffer strips will increase the diversity of flora and fauna in the otherwise monocultural landscape. The vegetation along the stream will also stabilize the stream banks and improve habitat for both fish and invertebrates within the stream.

    Operationalizing ecosystem-based adaptation: harnessing ecosystem services to buffer communities against climate change2016In: Ecology & society, ISSN 1708-3087, E-ISSN 1708-3087, Vol. 21, no 1, article id 31Article in journal (Refereed)
    Abstract [en]

    Ecosystem-based approaches for climate change adaptation are promoted at international, national, and local levels by both scholars and practitioners. However, local planning practices that support these approaches are scattered, and measures are neither systematically implemented nor comprehensively reviewed. Against this background, this paper advances the operationalization of ecosystem-based adaptation by improving our knowledge of how ecosystem-based approaches can be considered in local planning (operational governance level). We review current research on ecosystem services in urban areas and examine four Swedish coastal municipalities to identify the key characteristics of both implemented and planned measures that support ecosystem-based adaptation. The results show that many of the measures that have been implemented focus on biodiversity rather than climate change adaptation, which is an important factor in only around half of all measures. Furthermore, existing measures are limited in their focus regarding the ecological structures and the ecosystem services they support, and the hazards and risk factors they address. We conclude that a more comprehensive approach to sustainable ecosystem-based adaptation planning and its systematic mainstreaming is required. Our framework for the analysis of ecosystem-based adaptation measures proved to be useful in identifying how ecosystem-related matters are addressed in current practice and strategic planning, and in providing knowledge on how ecosystem-based adaptation can further be considered in urban planning practice. Such a systematic analysis framework can reveal the ecological structures, related ecosystem services, and risk-reducing approaches that are missing and why. This informs the discussion about why specific measures are not considered and provides pathways for alternate measures/designs, related operations, and policy processes at different scales that can foster sustainable adaptation and transformation in municipal governance and planning.

    I tigerns rike: en landskapsvetenskaplig studie om två underarters populationsförändring och ekologiska värde för landskapet2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study is a literature review and seek to find out two subspecies of tiger´s (Panthera tigris) population change and the reasons surrounding this on a time scale from 1970 to 2010. It also includes finding out the landscape and ecological consequences related to this, in order to discuss the sustainable conservation opportunities in the future. The two chosen subspecies for the study is the sumatran tiger and the amurtiger.

    The method has been mainly supported by previous studies, statistics and reports on the subject, but has allow themselves to be analysed and discussed in search for new fatc that can bring more light over the tigers popoulationchanges and the reserach of the tigerlandscape. Comparative studies with other predators, our Swedish wolf out and foray into the landscape, however, brings us a good picture of what could happen if the tiger continues to decrease or completely disappear from their landscape.

    Despite declining statistics, there were clear signs that fragmentation and human population growth are important factors to discuss the tiger's decline. The sumatran tiger was shown to be dangerly threatened by deforestation and human population growth in Sumatra, while the amurtiger seemed to be more resistent despite earlier researches has shown. An explanation for this might be the fact that the two subspecies range has been analyzed the same way despite large differences in environment and sieze and this can play a big role in my results that differes from earlier reserach results. It is clear, however, that humans general attitude toward predatos in their local area, so called human-wildlife conflicts, complicates the issue of conservation of the tiger when damage caused by the predators can be fatal and not to easy or affordable to compensate.

    Kan gullstånds hålla stånd?- återinventering av Senecio paludosus i Kristianstad Vattenrike 20122013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease. Despite this the future looks stable for fen ragwort in KristianstadVattenrike where several very strong premises exist in the region.

    Skapa grön infrastruktur för nyckelbiotoper med kantzoner runt värdefulla Vatten.: GIS-analys i Dalarna för bättre biodiversitet i skogsbruket2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna studie undersöker förslaget att kombinera utökade kantzoner med nyckelbiotoper med en matrix av hyggesfri skog. Om det här förslaget hade varit framgångsrikt i praktiken hade det medfört många fördelar för biodiversiteten i skogar och vattendrag. Genom analys med GIS-program analyserar studien ifall nyckelbiotoper har en tendens med att ligga nära vatten, och hur mycket skog och nyckelbiotop hade inkluderats i ett antal hypotetiska utökade kantzoner. Studiens resultat visar dock att det inte finns ett kausalt samband med att nyckelbiotoper skulle ligga nära vatten, och mängden skog och nyckelbiotop som skulle ha inkluderats i de hypotetiska kantzonerna är försumbart.
