Species with similar resource requirements are commonly assumed to competitively exclude each other, unless they differentiate their ecological niches. Hence, parasitoid wasps that use the same host species need to find some way to avoid competition. The aim of this study was to identify the role of volatile cues from oilseed rape plants and the larval host in niche separation between three coexis
We reconstructed the past coastal environment of the Baltic Sea from c. 7300 to 3500 cal. a BP, with a focus on sea surface salinity (SSS). To quantitatively determine the SSS, two methods were employed: measurements of 87Sr/86Sr ratios in mollusc shells (SSSS r) and process length variations of dinoflagellate cysts Operculodinium centrocarpum (SSSpl). The SSSS r was ~6–7 between 6800 and 6400 cal
Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in paleolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This synthesis investigates paleolimnological records that display apparent regime shifts and characterizes the shift
We documented the annual cycle of the carbon isotopic composition of dissolved inorganic carbon (δ13CDIC) in the water columns of the Skagerrak and Baltic Sea to obtain an increased understanding of the processes involved controlling the carbon isotopic distribution in shelf seas. The lowest δ13CDIC values (-4.9‰) were found in the low-oxygen, brackish Baltic bottom water whereas the highest value
Decentralized anaerobic digestion (AD) of manure and organic residues is a possible strategy to improve carbon and nutrient cycling within agricultural regions, meanwhile generating renewable energy. To date, there has been limited adoption of decentralized AD technology in industrialized countries owing to low profitability for plant operators. There remains a need to demonstrate the wider sustai
Climate change is not only changing the Arctic environment and ecosystems: it is also opening up the idea of the region as a last frontier to be explored. Recent representations of the future for the Arctic have become closely associated with various business-friendly opportunities as the land and sea ice is melting: They often represent so-called win-win solutions to climate change, also for Arct
The relationship between pesticides and pollinators, while attracting no shortage of attention from scientists, regulators, and the public, has proven resistant to scientific synthesis and fractious in matters of policy and public opinion. This is in part because the issue has been approached in a compartmentalized and intradisciplinary way, such that evaluations of organismal pesticide effects re
Towards a Cultural Politics of Climate Change provides a new perspective on how climate change matters in policy-making, business and everyday life. It argues that the work of low carbon transitions takes place through the creation of devices, the mobilisation of desires, and the articulation of dissent. Using case studies from the US, Australia, and Europe, the book examines the creation and cont
The footprint of climate change is now clearly visible within the culture industries. Museum exhibitions are held, newspaper headlines constructed, novels are written, films are screened and various art forms are provoked by and around the themes of the changing climate and its societal implications. This explicit cultural dimension, alongside the complex scientific, economic, social and political
There is a well-known story in climate change circles about the campaign run by opponents of action on climate change in the United States in the run-up to the Kyoto Protocol in 1997. A prominent ad in the campaign featured a stereotypical soccer mom, who declared: “The government wants to take away my SUV” (Schneider 2002). The ad is usually read in terms of the fossil fuel corporations’ strategy
The financing of climate measures in developing countries – climate finance – is an increasingly important issue in global climate governance. While a growing body of literature has highlighted the importance of bureaucratic actors within governments as a factor influencing political decisions, quantitative studies on climate finance have so far only focused on extra-governmental factors. We argue tha
Species-rich sandy calcareous grasslands are threatened by land use change, eutrophication and acidification. Disturbance is vital for the persistence of characteristic sandy calcareous grassland species because it provides habitats with low competition, and can lead to increased pH and decreased nutrient availability, which favour many threatened species. Today many sandy calcareous grasslands la
The occurence of introduced and native species and hybrid cultivars of Nuphar and Nymphaea in Sweden is discussed and a preliminary diagnostic key is presented. Swedish occurences of escaped Nuphar advena, Nymphaea ×marliacea, N. ×thiona and N. ×laydekeri are reported for the first time.
A rapid shift from traditional Sanger sequencing-based molecular methods to the phylogenomic approach with large numbers of loci is underway. Among phylogenomic methods, restriction site associated DNA (RAD) sequencing approaches have gained much attention as they enable rapid generation of up to thousands of loci randomly scattered across the genome and are suitable for nonmodel species. RAD data
