Scenario: Using adaptive dynamic theory, expose a monomorphic prey population to two habitat types and a visual predator. Questions: What circumstances can lead to the evolution of polymorphic crypsis? How is the outcome affected by the dispersal pattern of the prey and predator, by the amount of predation, and by the trade-off strength between the habitats? Mathematical method: I modelled three d
It is relevant to consider uncertainty in individual predictions when quantitative structure-activity (or property) relationships (QSARs) are used to support decisions of high societal concern. Successful communication of uncertainty in the integration of QSARs in chemical safety assessment under the EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) system can be faci
Indonesia has experienced rapid land use change over the last few decades as forests and peatswamps have been cleared for more intensively managed land uses, including oil palm and timber plantations. Fires are the predominant method of clearing and managing land for more intensive uses, and the related emissions affect public health by contributing to regional particulate matter and ozone concent
An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. The physical properties of these functions are studied and possible applications are suggested. A fragmentation model for multigl
This study aims to verify the effect of physically removing the outer surface of contaminated concrete on total contents and on potential mobility of pollutants by means of leaching tests. Reclaimed concrete from 3 industrial sites in Sweden were included: A tar impregnated military storage, a military tar track-depot, as well as concrete constructions used for disposing of pesticide production su
Predictive models used in decision making, such as QSARs in chemical regulation or drug discovery, call for evaluated approaches to quantitatively assess associated uncertainty in predictions. Uncertainty in less reliable predictions may be captured by locally varying predictive errors. In the current study, model-based bootstrapping was combined with analogy reasoning to generate predictive distr
Over the past 30 years a vast number of studies have demonstrated the presence of pharmaceutical residues in the environment. But still knowledge is scarce regarding the interaction of these emerging pollutants with various matrices in nature. A chromatographic system with on-line detection was devel- oped to perform a sorption study of six selected pharmaceuticals to four natural sediments and de
Fish are more sensitive to introduced disturbances from synthetic endocrine disrupting compounds during early life phases compared with mature stages. 17α-Ethinylestradiol (EE2), which is the active compound in human oral contraceptives and hormone replacement therapies, is today ever present in the effluents from sewage treatment plants. EE2 targets and interacts with the endogenous biological sy
Ancient DNA trapped in the matrices of ceramic transport jars from Mediterranean shipwrecks can reveal the goods traded in the earliest markets. Scholars generally assume that the amphora cargoes of 5th-3rd century B.C. Greek shipwrecks contained wine, or to a much lesser extent olive oil. Remnant DNA inside empty amphoras allows us to test that assumption. We show that short 100 nucleotides of an
Estrogen receptors (ers) not only are activated by hormones but also interact with many human-derived environmental contaminants. Here, we present evidence for four expressed er genes in Atlantic salmon cDNA - two more ers (erα2 and erβ2) than previously published. To determine if er gene expression differs between two adult life-stages we sampled 20 adult salmon from the feeding phase in the Balt
The consequences of climate change for bird populations have received much attention in recent decades, especially amongst cavity-nesting songbirds, yet little has been written on ducks (Anatidae) despite these being major elements of wetland diversity and important quarry species. This paper reviews the major known consequences of climate change for birds in general, and relates these to the limi
Popular Abstract in English Neuroplasticity is the brain´s capacity to respond to inner and outer challenges with functional and structural reorganizations. An aberrant activation of neuroplasticity pathways may contribute to the development of neurological disease. In the case of Parkinson’s disease (PD), the induction of motor complications by L-DOPA pharmacotherapy is generally regarded as an eNeuroplasticity is the brain´s capacity to respond to inner and outer challenges with functional and structural reorganizations.

There is increasing interest in the use of arbuscular mycorrhizal fungi (AMF) for ecological restoration, as AMF can improve plant nutrition and growth. However, some AMF can have negative effects on plant growth. It is therefore critical that restoration strategies incorporate appropriate AMF. This research investigated differences in growth and survival of Podocarpus cunninghamii (mountain tōtar
Popular Abstract in English Resistant to drug induced apoptosis and uncontrolled proliferation are biggest hurdles of cancer treatment. Bcl-3 is a proto-oncogene involved in both survival and proliferation in numerous cancers. In this thesis we investigated the molecular mechanisms through which Bcl-3 facilitates the survival and proliferation of cancer cells, furthermore we aimed to identify the Bcl-3 is a proto-oncogene and belongs to the inhibitor of κB (IκB) family and is known to be upregulated in numerous cancers. Bcl-3 can initiate transcription of different genes involved in cell survival and cell growth. Cell proliferation is achieved through binding of Bcl-3 to cyclin D1 promoter and facilitates the rapid transition from G1 to S phase. The aim of this thesis was to investigate th
In generally, there is a phenomenon of “free rider” in the establishment of national oil reserves for different countries, which means that they have the tendency of underestimating the strategic oil reserves. This paper attempts to explain this phenomenon from the perspective of non-cooperative game theory. It also analyzes the establishment of strategic oil reserve among different countries base
Plant size is a major predictor of ecological functioning. We tested the hypothesis that feeding damage to plants increases with plant size, as the conspicuousness of large plants makes resource finding and colonisation easier. Further, large plants can be attractive to herbivores, as they offer greater amounts and ranges of resources and niches, but direct evidence from experiments testing size e
To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. Com
Background-Conjugated linoleic acids (CLAs), a group of fatty acids shown to have beneficial effects in animals, are also used as weight loss supplements. Recently, we reported that the t10c12 CLA-isomer caused insulin resistance in abdominally obese men via unknown mechanisms. The aim of the present study was to examine whether CLA has isomer-specific effects on oxidative stress or inflammatory b
Abstract Following the 2004 EU-enlargement, the UK granted free movements of workers to nationals from the eight new member states (A8). There was a widespread concern in other European countries regarding the expected large inflow of A8 migrants, and consequently twelve of the old EU member states decided to implement transitional restrictions. This lead to a relatively large inflow of A8 migrant
