Popular Abstract in Swedish För över 100 år sedan upptäckte den franske naturalisten Jean-Henri Fabre att en nattfjärilshona som han hade på sitt skrivbord lyckades attrahera åtskilliga hanar, trots att honan var gömd bakom ett skynke och hannarna således inte kunde se henne. Fabre gissade att det var någon för honom okänd doft som låg bakom mysteriet. I slutet av 1950-talet identifierades det förMoths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland. The enzymes involved are fatty acyl desaturases, pheromone gland fatty acyl reductases (pgFAR), β-ox

The Anthropocene narrative portrays humanity as a species ascending to power over the rest of the Earth System. In the crucial field of climate change, this entails the attribution of fossil fuel combustion to properties acquired during human evolution, notably the ability to manipulate fire. But the fossil economy was not created nor is it upheld by humankind in general. This intervention questio

Abstract in UndeterminedAgeism has been described as different from other forms of discrimination and paradoxical in the sense that "nonold" people discriminate against their "future selves." The argument of this article is that nonold people may uphold ideas about older people as "the other" by constructing their own future selves as "essentially different" from that of older people of the presen

In this paper, we have investigated, by means of quantitative and statistical methods, stability and change in cultural vocabulary of Indo-European in Europe, with a focus on agriculture. For this purpose we have created a culture vocabulary list with lexical head words, organized into subcategories based on their role and function in a cultural system, the purpose of which is to give a representa

Mycket har skett i jordbruket det senaste århundradet. Vi har rört oss från ett småbondesamhälle till ett mekaniserat, industrialiserat och kapitaliserat jordbrukssamhälle med en global marknad. Denna intensifiering av jordbruket har lett till förlust och fragmentering av biotoper vilket givetvis har påverkat den biologiska mångfalden negativt. När arter minskar eller försvinner riskerar vi även aModern agricultural practices have led to an intensification of the agricultural landscape which has negatively affected both biodiversity and the ecosystem services it provides. In my thesis I have used ecological theory of optimal foraging to try and explain how landscape structure, landscape composition and agricultural management can explain the loss of biodiversity and how remedies can effici
