Patch use theory and the marginal value theorem predict that a foraging patch should be abandoned when the costs and benefits of foraging in the patch are equal. This has generally been interpreted as all patches being abandoned when their instantaneous intake rate equals the foraging costs. Bayesian foraging – patch departure is based on a prior estimate of patch qualities and sampling informatio
The biogeography of speciation and what can be learned about the past mode of speciation from current biogeography of sister species are recurrent problems in evolution. We used a trait- and individual-based, eco-evolutionary model to simulate adaptive radiations and recorded the geographical overlap of species during and after evolutionary branching (speciation). We compared the spatial overlap a
BACKGROUND: The pancreas is the main target of the trophic effect of cholecystokinin (CCK), with a transient increase in cell proliferation and persistent effect on DNA content and weight gain when given continuously. Whether CCK exerts similar effects on the liver and biliary tract is not known. Most studies on this subject have hitherto been done in the rat. The aim of the present experiments wa
In the existing literature on welfare state typologies, the concept of the universal welfare state is not defined precisely enough to allow for comparisons of universality over time and between countries. In this paper, I discuss some problems with the way the term 'the universal welfare state' has been used and I suggest possible solutions. Among other things, I propose that the term 'universalit
On the basis of one specific event during World War two, the Swedish Defence Loan campaign in 1940, the text studies how the Bernadotte family – as one homogenous entity as well as separate family members – acted and staged themselves in the media and the public sphere.
This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic. Conseque
Locally adapted ecotypes can constitute an important part of the biodiversity, especially in young floras with few endemic species. However, the origins, distinctness and conservation value of many ecotypes remain uncertain because genetic data are lacking or no common-garden study has been carried out. In the present study, we evaluated the distinctness and genetic structure of a phenotypically d
Wild geese are increasing in agricultural and urban settings across Europe, leading to widespread human–geese interactions. This study examined how the public’s acceptance of geese (attitude and acceptance capacity) varied depending on place dimensions, interactions with geese in different settings (place-based experience), and psychological factors, including wildlife value orientations, beliefs
Social deprivation and marginalization in urban areas are hardships that are not necessarily limited to developing countries. Around 80 million Europeans today live in conditions that fall within the definition of poverty. However, certain areas are more prone to affliction than others. Such estates usually consist of concrete slab high-rise buildings and are often characterized by high levels of
Background: Inferior placement of a femoral stem is predictive for early loosening and failure, but does restoration of the original hip anatomy benefit the function and survival of a total hip replacement? Methods: Seventy-five patients with primary unilateral hip osteoarthritis operated with an uncemented anatomical stem were randomized for either standard or modular stems. We used 50 ABG II ste
While current instruments of EU economic policy coordination helped stave off a full- scale depression, the post-2007 global financial and economic crisis has revealed a number of weaknesses in the Stability and Growth Pact, the EU framework for fiscal surveillance and fiscal policy coordination. This paper provides a diagnosis of how the SGP faired ahead and during the present crisis and offers a
Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model organism for the study of generalized insect development, and an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved the ability to interact with a diverse chemical environment, as shown by large expansions in odorant and gustatory recepto
