A fundamental assumption of theories of the ecology and evolution of inducible defences is that protective responses to attacks by parasites or predators should not only have benefits, but also costs. The vertebrate immune system is by far the best studied example of an inducible defence, yet little is known about the costs of an immune response, especially in natural populations. To test: if an i
Within many species, larger offspring have higher fitness. While the presence of an offspring size–fitness relationship is canonical in life-history theory, the mechanisms that determine why this relationship exists are unclear. Linking metabolic theory to life-history theory could provide a general explanation for why larger offspring often perform better than smaller offspring. In many species,
In this article five scenarios for fully electric road transport in Sweden are compared, looking at the total system cost for different combinations of battery systems, vehicle equipment and charging solutions, including the use of Electric Road Systems (ERS). The main objective of this work is not to provide accurate price estimations, but to help understanding the main cost drivers of transport
Majoritarian electoral systems are associated with lower levels of redistribution, but there is no consensus on the working mechanisms behind this. This thesis aims to provide a new explanation. We connect research on elections and individual policy preferences and develop a theory in which low levels of redistribution is explained by large shares of high income groups in the legislature in majori
Macroeconomic crises are common as well as economically, socially and politically costly. Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances are often unprepared for a crisis. Deficits and debt levels prior to the crisis are commonly too high, limiting the government’s ability to support the economy through the
Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: Fir
This paper analyzes the impact of variables suggested by the trade-off theory and the pecking order theory, on publicly listed Swedish firms in a sample period of 8 years, ranging from 2003-2010. Also the relationship between leverage and weighted average cost of capital (WACC) is studied for the same set of firms and time periods. The model used is based on panel regression with fixed and random
Decarbonizing the energy-intensive and natural resource-based industries is possible but may sub-stantially increase the cost of production. Whether such cost increases will reduce economic welfare depends on how the downstream industries respond to the higher cost for intermediate goods. In this paper, we explore how downstream industries in the EU15 responded to upstream carbon technology shocks
17 april 2026 12:00 till 13:00 | Event From medical imaging to drug discovery, AI is reshaping biomedical research. But it also requires significant energy and resources. Join this panel during Sustainability Week to explore AI’s footprint, its potential, and what responsible practice could look like in Sweden. During Sustainability Week in Lund, the Sustainability Committee at Lund Stem Cell Cent

TEDDY studien samlar in information 40–50 gånger fram till 15 års ålder beroende på om forskningspersonen har autoantikroppar eller ej.Det är information av olika typ som samlas in. Vid varje besök analyseras sju olika autoantikroppar, som är biomarkörer för autoimmun (typ 1) diabetes, celiaki och sköldkörtelinflammation. IAA, GADA, IA-2A och ZnT8A är biomarkörer för autoimmun (typ 1) diabetes. tT
Enheten för forskningsdata (Research Data Office, RDO) stöttar forskare vid Lunds universitet i hela forskningsprocessen genom att ge vägledning till rätt stöd,verktyg och tjänster för hantering av forskningsdata. Enheten har en samordnande roll och ska verka för att stärka kvaliteten och genomslaget i forskningen, exempelvis genom att stötta forskare att göra data mer tillgänglig, säker och hållbLund University Research Data Office (LU RDO) supports researchers at Lund University throughout the research process by providing guidance on the right support, tools and services for managing research data. The office has a coordinating role and will work to strengthen the quality and impact of research, for example by supporting researchers to make data more accessible, secure and sustainable,
Popular Abstract in Swedish Staren i jordbrukslandskapet Under de senaste tre decennierna har staren (Sturnu's vulgari's) i likhet med många andra fågelarter knutna till jordbrukslandskapet minskat kraftigt i antal, både i Sverige och i stora delar av västra och norra Europa. Det finn's flera tänkbara förklaringar till detta, men eftersom jordbruket under samma tidsperiod genomgått stora förändriThe European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. For starlings in Southern Sweden the amount of pasture in the landscape surrounding breeding colonies is the key factor. We found a positive relat
With increasing pressures to reduce greenhouse gas emissions, heavy-duty freight is moving to electrification, but this shift remains challenging due to high energy demand, long operating hours, strict delivery schedules, and limited tolerance for charging downtime. This thesis examines whether battery swapping combined with Battery-as-a-Service can contribute to the sustainability transition of h
Germany remains the only large country in the world without a general speed limit on highways. One of the main arguments for this policy is that lower speeds represent a travel time cost that is not outweighed by benefits, such as a reduction in greenhouse gas emissions. As transport decision making in the European Union is based on cost-benefit analysis (CBA), this paper compares the value of tra
