Oil palm expansion results in a loss of biodiversity and associated ecosystem services. However, there are factors that influence the severity of these impacts and enhancing biodiversity within plantations is important. In the present study, we examined the role of epiphytes for supporting arthropod communities in oil palm plantations in Sumatra, Indonesia. We considered the effects of landscape c
Aim The impact of multiple stressors on biodiversity is one of the most pressing questions in ecology and biodiversity conservation. Here we critically assess how often and efficiently two main drivers of global change have been simultaneously integrated into research, with the aim of providing practical solutions for better integration in the future. We focus on the integration of climate change
Forest degradation, forest fires, and wildlife poaching have devastated biodiversity in Indonesia. To assess the impact of forest degradation and the potential for recovery, we used birds as a proxy for biodiversity and assessed density estimates (hereafter density) in the degraded lowland forest of Harapan Rainforest Ecosystem Restoration Concession (HRF) in Sumatra. In this study, a total of 149
We argue that the current system of agri-environment management in the European Common Agricultural Policy is ineffective at conserving biodiversity in part because it promotes fragmentation instead of collaboration of actors, thus hindering coordinated biodiversity management. Actor fragmentation is reinforced by the Common Agricultural Policy (CAP) in three ways: (1) through targeting individual
During the last two decades, the Swedish education system for higher education has been reformed and expanded. During this period of change both bourgeois and social democratic parties have had the governmental power. Therefore, the following paper seeks to examine which party-political differences there are in the Swedish higher education from 1991 to 2014. This paper answers that question by qua
Fitnesskulturen växte fram i USA och blomstrade under 1970-talet men har sedan dess spridit sig över hela världen. Idag hålls tävlingar och evenemang inom fitness i Sverige och fitnessbranschen växer sig större. Användningen av dopingpreparat förekommer i alla sporter och även inom fitnessbranschen. Den tidigare forskningen visar på studier som tar upp dopingpreparat som problem men i kontexten fi
The critical levels for ozone effects on vegetation have been reviewed and revised by the LRTAP Convention. Eight new or revised critical levels based on the accumulated stomatal flux of ozone (POD gamma, the Phytotoxic Ozone Dose above a threshold flux of Y nmol m(-2) PLA s(-1), where PLA is the projected leaf area) have been agreed. For each receptor, data were combined from experiments conducte
Soil phosphorus (P) composition changes with ecosystem development, leading to changes in P bioavailability and ecosystem properties. Little is known, however, about how soil P transformations proceed with ecosystem development in boreal regions. We used 1-dimensional P-31 and 2-dimensional H-1, P-31 correlation nuclear magnetic resonance (NMR) spectroscopy to characterise soil organic P transform
Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr
Ciliate assemblages play a significant role in the microbial food web. The effects of environmental temperature on assemblage composition may be influenced by abiotic factors such as seasonality and disturbance, but the effects of temperature on ciliate assemblages found on different substrata have not been explored. Sandy bottoms and submerged rocks harbour dissimilar ciliate assemblages, and it
Examensarbetet är utfört vid Lunds Tekniska Högskola, avdelningen för Teknisk Geologi i samarbete med Vattenfall Research and Development AB, med syfte att undersöka åldringsfenomen och nedbrytningsprocesser av kraftverkstunnlar i berg. Livslängden för kraftverkstunnlar antas normalt vara mellan 50 och 100 år, varför många kraftverkstunnlar idag uppnått en ålder på mer än 50 år. Kraftverkstunnlar
Att diagnostisera en hörselnedsättning och inleda habilitering så tidigt som möjligt på små barn har visat sig vara av stor betydelse. Genom åren har flera olika diagnostiska metoder utvecklats får att kunna utföra hörselmätningar på små barn. I Linköping utarbetades 1996 ett datorstött mätsystem för barnaudiometri. Systemet är en variant av tittlådeaudiometri, Visual Reinforcement Audiometry (VRA
Interactions between metals and natural organic matter (NOM) are of great environmental importance and one of the key factors influencing hydrolysis, solubility, and speciation of the metals. However, studying geochemically relevant metals like Al, Fe, and Cu is sometimes associated with analytical problems; for example Fe and Cu are both redox active. Gallium (Ga) is a non-redox active metal that
Predicting potential pollination services of wild bees in crops requires knowledge of their spatial distribution within fields. Field margins can serve as nesting and foraging habitats for wild bees and can be a source of pollinators. Regional differences in pollinator community composition may affect this spill-over of bees. We studied how regional and local differences affect the spatial distrib
Context Agricultural transformation and increased land use intensity often lead to simplified landscapes and biodiversity loss. For animals, one possible mechanism underpinning biodiversity loss in agricultural landscapes is the disruption of movements. The disruption of movements may explain, for example, why butterfly communities in agricultural landscapes are often dominated by generalist speci
Syftet med detta arbete är att utreda om brandmännens praktiska färdigheter har förändrats sedan utbildningen Skydd Mot Olyckor (SMO) trädde i kraft. I detta arbete förklaras praktiska färdigheter som ”hur väl man hanterar och är insatt i hur verktyg och redskap fungerar som ingår i brandmannayrket – t.ex. kedjesåg, klippverktyg, pumpar, motorkap med mera”. Vid Helsingborgs Brandförsvar där studieThe purpose of this study is to investigate if the practical skills of firemen have changed since the education Skydd Mot Olyckor, SMO (eng. Protection Against Accidents, SMO) was introduced. In this study, the term ”practical skills” is defined as ”how competently one handles and understands the use and function of tools used in the fireman profession, e.g. chainsaw, cutting tools, pumps and cros
Browning of surface waters, as a result of increasing dissolved organic carbon and iron concentrations, is a widespread phenomenon with implications to the structure and function of aquatic ecosystems. In this article, we provide an overview of the consequences of browning in relation to ecosystem services, outline what the underlying drivers and mechanisms of browning are, and specifically focus
