This paper addresses the complex interactions between settlement patterns and landscape dynamics in the Iščica floodplain (the Ljubljana Marshes, Slovenia) during the early and middle Holocene. This complex interaction can be observed on many nested spatial and temporal levels. The paper examines landscape and settlement dynamics on the micro-regional scale by exploring settlement patterns and LiDAR (Light Detection and Ranging) imagery, and on the settlement scale by analysis and radiocarbon dating of stratigraphic sequences from the Maharski prekop site.

To determine whether or not a contaminant has the potential to become a pollutant, its biological effects must first be established. The scientific discipline of toxicology considers the measurement of toxins, their mechanisms and the effects they have on the environment, its inhabitants and on human health. This chapter describes how contaminants behave in marine environments, how organisms are exposed to them and how they respond at the molecular, individual, population and ecosystem levels. Marine organisms exhibit a range of different responses and detoxification mechanisms that are used as the basis of approaches for measuring toxicity. The complex interactions of pollutants in the environment, their interactions with other toxicants and the large natural variability in toxic effects between species and individuals make this challenging. However, in order to regulate the production and discharge of pollutants it is critical that the impacts on ecosystems and ecosystem services are understood.

Conservation planning for climate change adaptation is only one in a long sequence of conservation paradigms. To identify priority locations for protected areas it must compete with three other contemporary paradigms: conservation of ecosystem services, optimizing conservation of ecosystem services and poverty alleviation, and reducing carbon emissions from deforestation and forest degradation. This chapter shows how conservation paradigms evolved, discusses the merits of different approaches to modelling potential impacts of climate change on biodiversity, and describes the hybrid BIOCLIMA model and its application to Amazonia. It then discusses conservation planning applications of the three other contemporary paradigms, illustrated by examples from Amazonia and Kenya. It finds that rapid paradigm evolution is not a handicap if earlier paradigms can be nested within later ones. But more sophisticated planning tools are needed to identify optimal locations of protected areas when climate is changing, and to use protection to mitigate climate change. These should encompass the complex interactions between biodiversity, hydrological services, carbon cycling services, climate change, and human systems.

An important trend in the food industry today is reduction in the amount of fat in manufactured foods. Often fat reduction is accomplished by replacing part of the natural fat with carbohydrates which serve to bind water and increase viscosity. It is in understanding the roles of these two major components of food, fats and carbohydrates, that freeze-fracture is so important. It is well known that conventional fixation procedures are inadequate for many food products, in particular, foods with carbohydrates as a predominant structural feature. For some food science applications the advantages of freeze-fracture preparation procedures include not only the avoidance of chemical fixatives, but also the opportunity to control the temperature of the sample just prior to rapid freezing.In conventional foods freeze-fracture has been used most successfully in analysis of milk and milk products. Milk gels depend on interactions between lipid droplets and proteins. Whipped emulsions, either whipped cream or ice cream, involve complex interactions between lipid, protein, air cell surfaces, and added emulsifiers.
