Looking beyond the flowers: associations of stingless bees with sap-sucking insects

The study addresses in vitro degradation potential of airborne Aspergillus and Penicillium/Talarmyces species originating from cultural heritage conservation premises. A series of rapid, cost effective biodegradation assays were performed to assess production of extracellular pigments, acids, and enzymes. Most of the isolates have demonstrated positive growth in at least one of the preformed tests. Strongest overall degradation potential was demonstrated for Penicillium brevicompactum, P. glabrum, and Talaromyces sayulitensis while Aspergillus domesticus, A. penicillioides, A. pseudoglaucus, and A. ruber did not exhibit positive reaction in any of the employed assays. Majority of isolates exhibited proteolytic and cellulolytic activity while carbonate dissolution was observed for only five tested fungi. Highest alteration of pH value in liquid media was documented for T. sayulitensis while A. niger and P. expansum exhibited strongest acid production on CREA. Certain isolates, mostly Penicillium species, displayed production of extracellular pigments. The results imply that many of the tested fungi have significant biodegradation capacity, indicating their potential to inflict structural and esthetic alterations on cultural heritage objects.

     

Local governing of climate change in Denmark: recasting citizens as consumers

This paper is concerned with the ways in which Danish municipalities seek to mitigate climate change through a range of governance strategies. Through the analysis of ten municipal climate plans using the framework of Mitchell Dean, as well as extensive ethnographic fieldwork in two municipalities, this paper explores how local climate change mitigation is shaped by particular rationalities and technologies of government, and thus seeks to illustrate how the strategies set out in the plans construe climate change mitigation from a certain perspective, thereby rendering some solutions more likely than others and recasting citizens as passive consumers who are to be guided to consume in more climate-friendly ways in the process.
