- Knowledge on basic biological functions of organisms is essential to understand not only the role they play in the ecosystems but also to manage and protect their populations. The study of biological processes, such as growth, reproduction and physiology, which can be approached in situ or by collecting exemplars and rearing them in aquaria, is particularly challenging for deep-sea organisms such as cold-water corals (CWCs). Present experimental work and monitoring of deep-sea populations is still a chimera. Only a handful of research institutes or companies have been able to install in situ marine observatories in the Mediterranean Sea or elsewhere, which facilitate for a continuous monitoring of deep-sea ecosystems. Hence, today’s best way to obtain basic biological information on these organisms is (1) working with collected samples and analysing them post-mortem and / or (2) cultivating corals in aquaria in order to monitor biological processes and investigate coral behaviour and physiological responses under different experimental treatments. The first challenging aspect is the collection process, which implies the use of oceanographic research vessels in most occasions, since these organisms inhabit areas between ca. 150 m to more than 1,000 m depth, and specific sampling gears. The next challenge is the maintenance of the animals on board (in situations where cruises may take weeks) and their transport to home laboratories. Maintenance in the home labs is also extremely challenging since special conditions and set ups are needed to conduct experimental studies to obtain information on the biological processes of these animals. The complexity of the natural environment from which the corals were collected cannot be exactly replicated within the laboratory setting; a fact which has led some researchers to question the validity of work and conclusions drawn from such undertakings. It is evident that aquaria experiments cannot perfectly reflect the real environmental and trophic conditions where these organisms occur, but: (1) in most cases we do not have the possibility to obtain equivalent in situ information and (2) even with limitations, they produce relevant information about 117 the biological limits of the species, which is especially valuable when considering potential future climate change scenarios. This chapter includes many contributions from different authors and it intends to be both, a practical “handbook” for conducting CWC aquaria work, while at the same time, to offer an overview on the CWC research conducted in Mediterranean labs equipped with aquaria infrastructure. Experiences from Atlantic and Pacific laboratories with extensive experience with CWC work have also contributed to this chapter, as their procedures are valuable to any researcher interested in conducting experimental work with CWC in aquaria. It was impossible to include contributions from all labs in the world currently working experimentally with CWCs in the laboratory, but at the conclusion of the chapter we attempt, to our best of our knowledge, to supply a list of laboratories with operational CWC aquaria facilities.

Bottendjuren påverkar fiskens hälsa

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Under 2000-talet har kustfiskens hälsostatus förändrats kraftigt. Det gäller framför allt en mycket tydlig uppgång i aktiviteten av ett avgiftningssystem i levern hos abborre, följt av en lika kraftig nedgång. Förändringen var så stor att den är svår att förklara med något annat än ett förändrat upptag av miljögifter. Djupare analyser visar ett starkt samband med förekomsten av bottenlevande djur. Det är möjligt att dessa bidrar till att återföra miljögifter från bottensediment till ekosystemet.

- Synopsis Safety regulation is society's way of keeping the genie of technology in the bottle, whilst still exploiting its power for creating wealth and change. It is a difficult compromise to make. Regulators often have a thankless task. If all seems to go well they are painted as too repressive and anti-technological; if disaster strikes, the searchlight of media attention increasingly focuses on them, looking for lax enforcement, blind eyes being turned and cosy relations with the regulated. This title explores the dilemmas of the regulator through case studies presented by the regulators themselves and through research-based analyses from different disciplines of the workings of the regulators and the regulatory system. More importantly it surveys the tools available to resolve the dilemmas and asks what we know about their successes and shortcomings and what can be learned over the boundaries of industries and technologies about the principles of successful safety regulation. Chapters are written by authors from seven countries, with an international perspective. They examine the role of certification, safety cases, strictly enforced detailed rules, professional regulation and self-regulation. The text covers new risks such as those from medical devices and biotechnology, as well as the well-known fields of nuclear power, chemical plants, mining, oil and gas production, railways and the traditionally difficult area of small companies.

What do people believe about memory?

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This book presents an authoritative overview of memory in everyday contexts. Written by an expert team of international authors, it gathers together research on some of the more neglected but revealing areas of memory, to provide a comprehensive overview of remembering in real life situations.Contributions from leading experts deal with a variety of important questions concerning everyday memory, from under-researched areas such as memory for odours, to more well known areas, like collective memory. Topics covered also include:Beliefs about memory and the metaphors used to discuss memoryThe relation between self-referent beliefs and actual memory performanceThe development of autobiographical memory.Everyday Memory summarises current knowledge and presents new interpretations and hypotheses to be explored by future research. It discusses aspects of human memory which are frequently ignored or dealt with only very briefly by ordinary textbooks and as a result will have a broad appeal for researchers and students.
