Short-term (three to four years) effects of forest harvesting on soil solution chemistry were investigated at two Norway spruce sites in southern Norway, differing in precipitation amount and topography. Experimental plots were either harvested conventionally (stem-only harvesting, SOH) or whole trees, including crowns, twigs and branches were removed (whole-tree harvesting, WTH), leaving residue piles on the ground for some months before removal. The WTH treatment had two sub-treatments: WTH-pile where there had been piles and WTH-removal, from where residues had been removed to make piles. Increased soil solution concentrations of NO3–N, total N, Ca, Mg and K at 30 cm depth, shown by peaks in concentrations in the years after harvesting, were found at the drier, less steep site in eastern Norway after SOH and WTH-pile, but less so after WTH-removal. At the wetter, steeper site in western Norway, peaks were often observed also at WTH-removal plots, which might reflect within-site differences in water pathways due largely to site topography.

Advances in the identification of attraction of mirids to semiochemicals has provided the opportunity to exploit synthetically produced sex pheromones and plant produced compounds for controlling pest species in crops. Sex pheromones of mirids are important for long range attraction of males to females and plant volatiles indicate egg laying sites for female mirids. The European tarnished plant bug (Lygus rugulipennis) causes large yield losses (10->80%) in conventional and organic strawberry. Following the successful development of these semiochemicals in combination with effective traps we investigated the ability of a mass trapping system to reduce damage in strawberry crops in combination with another strawberry pest, strawberry blossom weevil (Anthonomus rubi). Attractive traps and lures with host plant volatiles and sex or aggregation pheromones were deployed in strawberry crops at 50 per hectare in several European countries. Trap catches were monitored in relation to fruit damage and compared to untreated crops. Traps successfully captured both target pest species. In this paper we will present the results of the potential to reduce crop damage using mass traps and discuss the benefits and difficulties in using these techniques as part of integrated or organic pest management.

This book presents a unique collection of 50 methods for exploring the actions, relationships and material contents of wardrobes. Organised as a practical guide to gathering information about people and their clothing beyond the point of purchase, it includes visual, tactile and verbal methods and others which involve making together, loitering and a session in the gym. With contributions from four continents from both in- and outside academic circles, this book and the real lives of wearers of clothes that are its focus, create a powerful new narrative of a more diverse, resourceful, emancipatory and holistic fashion and clothing system.
