Males should invest in mate attraction, mate guarding and paternal care in relation to the marginal fitness value of each of those behaviours. Since time and energy are limited, trade-offs between these activities are expected. This study demonstrates that monogamous male European starlings (Sturnus vulgaris) decrease their paternal effort in response to increased opportunities to attract addition
In altricial birds, growth rates and nestling morphology vary between broods. For natural selection to produce evolutionary change in these variables, there must exist heritable variation. Since nestling traits are not any longer present in parents, traditional offspring-parent regressions cannot estimate heritabilities of these. In this study, a partial cross-fostering experiment was performed, w
The extent to which male birds in polygynous species with biparental care assist in nestling feeding often varies considerably between nests of different mating status. Both how much polygynous males assist and how they divide their effort between nests may have a profound effect on the evolution of mating systems. In this study we investigated how males in the facultatively polygynous European st
New visionary concepts need to be created to enhance the pursuit of sustainable development at a global scale, to respond to policies and international multilateral agreements in line with political commitments already made (like the Millennium Development Goals) and innovative approaches are called for to ensure the coherence of integrated policy-making at EU level.
The upcycling trend has received renewed attention in the past few years due to growing concerns for the environment related to increased resource consumption and waste volumes. Indeed, cities across the world are supporting resource upcycling initiatives by establishing do-it-yourself (DIY) repair cafes and makerspaces as a means to transform societies towards sustainable develop-ment. However, t
Analoga brädspel har sett en renässans i popularitet de senaste åren, vilket är intressant av två olika anledningar. Dels för att det är ett analogt medium, och dels för att de utgör en analog umgängesform. Ett fysiskt objekt som får människor att samlas och umgås på samma plats, trots att man enklare kan spela tillsammans online istället. Med ett fokus på socialitet så belyser jag i min studie de
In this paper we show that several metals, elements and energy resources are about to run into scarcity within the next decades, and most elements within some centuries. A new global systems model was assembled to analyse this scarcity as a continuation of the model used in the Limits-to-Growth World3 model. We show that this scarcity will lead to “peak wealth”, “peak population”, “peak costs”, “p
This paper provides a systemic analysis of complex dynamic issues associated with resource use, scarcity and efficiency by applying systems thinking with respect to sustainability criteria. Casual loop diagramming methodology is adopted to create a conceptual model to better understand the interconnected patterns, cause effect relations and feedbacks between the three dynamic complex systems that
De senaste årens teknologiska utveckling, med sociala medier i spetsen, har stöpt om samtidens medielandskap. En effekt av denna utveckling är att en ny direkthet skapats mellan offentlig person och gemene man. Detta nya förhållande innebär att offentliga personer numera både kan granskas och när skäl föreligger, bojkottas, av allmänheten. Fenomenet har kommit att benämnas som “cancel culture”. Fö

Hösten 2008 domineras nyhetsflödet av rapporter om den finansiella kris som under årets senare hälft drabbat världen. Samtidigt finns en utbredd oro om en långvarig recession. I sådana lägen, då landet befinner sig i en lågkonjunktur, försöker Riksbanken stävja den genom att sänka räntorna och öka den ekonomiska aktiviteten i samhället. Reporäntesänkningarna under oktober fick dock en begränsad ef
The world supply and turnover of copper was modelled using simple empirical estimates and a COPPER systems dynamics model developed for this study. The model combines mining, trade markets, price mechanisms, population dynamics, use in society and waste as well as recycling, into a whole world system. The degree of sustainability and resource time horizon was estimated using four different methods

The search for greener ways of producing plastic has been a very popular field for the last few years. One avenue of research focuses on separating plastic production from the fossil fuel industry by finding bio-based alternatives. This is the case of the research conducted by our collaborators at Biotechnology who are trying to use Escherichia coli to produce 1,4-butanediol, a precursor to many p
Biodiversity depletion directly impacts businesses and society by influencing ecosystem services. Despite the growing recognition of biodiversity loss as a significant crisis, many companies have not yet sufficiently integrated broader nature considerations into their strategies. The Science-Based Targets Network (SBTN) aims to facilitate nature including biodiversity target setting within corpora
This paper examines which factors that influence the price of the housing market. By using data from Sweden and Denmark between year 1993 - 2020 with credit growth, dwellings completed, an interest-spread and population growth as explanatory variables in the model. The study aims to explain the growth in the housing market with two separate multiple linear regression models. The results show that
Populärvetenskaplig sammanfattning: Himalayas glaciärer både växer och blir mindre som ett svar på klimatförändringarna. Den dominerande trenden är att ismassor minskar, speciellt för mindre glaciärer. Allt eftersom glaciärer drar sig tillbaka, ändras hydrologin och vattentillgängligheten, både uppströms och nedströms inom dräneringsområdet. Denna förändring är mest tydlig på hög altitud där jordbHimalayan glaciers are both growing and shrinking as a response to global climate change. The major trend is a loss of ice sheets, especially among the smaller glaciers. As glaciers retreat there is a change in hydrology and seasonal water availability both upstream and downstream of the river basins. This is most apparent in high altitude and glacierfed areas where meltwater is the main (sometime
