- To accept the nomination to become the supervisor of a PhD candidate is not only to step into a specific, challenging and potentially rewarding relationship, but also to enter a new zone of uncertainty: what kind of contribution to this relationship is expected from me? In what ways is this new professional task framed and supported by the institutional context to which I belong? What do I gain from becoming a supervisor? In this chapter we draw together our experiences of spending many hundreds of hours listening to and discussing with supervisors of PhD candidates from a wide variety of research domains. We use our experiences from ten years of arranging pedagogical support for supervisors in the form of courses and seminars, and use what we have learned in these meeting places as material to describe how we perceive the cultural and contextual conditions for supervising PhD candidates both in general and in the emerging field of artistic research. The aim is therefore not to describe or evaluate our pedagogical efforts, but to use what we have encountered and reflected on in seminars with supervisors over the years. Another aim is to shed some light on the cultural and contextual conditions for supervising artistic research by comparing and contrasting the situation of the supervisors in this relatively new field with the situation in other fields of research. A more personal aim is to try to disentangle some of the persistent puzzlement that followed us through the years with Konstnärliga forskarskolan (KFS). Why was it that over and over again we were troubled by a feeling that the supervisors, compared to our expectations, were not regarded as being crucially important for the development of artistic research?In this chapter we will first discuss the importance of supervisors for doctoral education and for the regeneration and development of research, both in general and for new fields, with continuous references to artistic research, as it was mirrored to us through KFS. We will then continue along a road where we look at a number of contextual conditions (such as the learning trajectories of artists) and practiced concepts (such as interdisciplinarity and practice-based research), where we have experienced intriguing differences in artistic research when compared to other research environments. Finally, we offer two scenarios staging the institutional and cultural conditions for supervising artistic research in two quite different ways. They are constructed as ideal types and as a tool to disentangle some of the ambiguities supervisors have to face in the real settings where they meet their PhD candidates, and where everything is mixed up, as in life itself. Finally, we end our chapter by pointing out a ghost scenario, which we hope will disappear with the continued development of artistic research.

Conodonts from the Early Triassic Microbialite of Guangxi (South China) : Implications for the Definition of the Base of the Triassic System

Tidskriftsartikel (refereegranskat)abstract
- We describe a new Early Triassic (Griesbachian) succession of conodont faunas from a high-resolution sampling of the basal Early Triassic microbial limestone and the base of the overlying unit at the Wuzhuan section (Nanpanjiang Basin, Guangxi, South China). The microbial limestone records the earliest phase of the Early Triassic biotic recovery after the end-Permian mass extinction. For the first time, rich conodont faunas are reported from within the microbialite. The faunas from Wuzhuan are largely dominated by anchignathodontids, including several Isarcicella species, which were previously documented only from strata above the microbialite. A total of 14 conodont species assigned to three genera is recorded from the Wuzhuan section. Starting from the base of the microbialite upwards, several species are sequentially added to the conodont assemblage. The alpha diversity peaks at the top of the microbialite. The conodont record in the considered microbialite interval at Wuzhuan is presumably unaffected by local ecological changes. It therefore more likely represents an evolutionary rather than an ecological pattern. We compare the Wuzhuan's conodont record with a well-supported phylogenetic model and suggest that the sequence of first occurrences at Wuzhuan is the closest to the true' sequence of evolutionary events that took place during this Griesbachian radiation of anchignathodontids. Based on comparisons with the GSSP section at Meishan, we suggest further that the first occurrence of Hindeodus parvus in Meishan does not correspond to its first appearance datum.

Tidskriftsartikel (refereegranskat)abstract
- A new Early Triassic marine fauna is described from an exotic block (olistolith) from the Ad Daffah conglomerate in eastern Oman (Batain), which provides new insights into the ecology and diversity during the early aftermath of the Permian-Triassic Boundary mass extinction. Based on conodont quantitative biochronology, we assign a middle Griesbachian age to the upper part of this boulder. It was derived from an offshore seamount and yielded both nektonic and benthic faunas, including conodonts, ammonoids, gastropods and crinoid ossicles in mass abundance. This demonstrates that despite the stratigraphically near extinction at the Permian-Triassic Boundary, Crinoidea produced enough biomass to form crinoidal limestone as early as middle Griesbachian time. Baudicrinus, previously placed in Dadocrinidae, is now placed in Holocrinidae; therefore, Dadocrinidae are absent in the Early Triassic, and Holocrinidae remains the most basal crown-group articulates, originating during the middle Griesbachian in the Tethyan Realm. Abundant gastropods assigned to Naticopsis reached a shell size larger than 20 mm and provide another example against any generalized Lilliput effect during the Griesbachian. Whereas the benthic biomass was as high as to allow the resumption of small carbonate factories, the taxonomic diversity of the benthos remained low compared to post-Early Triassic times. This slow benthic taxonomic recovery is here attributed to low competition within impoverished post-extinction faunas.

Forskningsöversikt (refereegranskat)abstract
- Integration of new isotopic data and earlier biostratigraphic information from eight sections through the terminal Ordovician (Pirgu and Porkuni stages) of the Siljan district, Sweden, allows a more precise correlation of sections in terms of biostratigraphy and carbon isotope dating. Four levels with positive delta C-13 excursions are identified (from bottom) - the Moe, an unnamed excursion, Paroveja and Hirnantian Carbon Isotope Excursion (HICE). The delta C-13 values through the Boda Limestone are 1-2 parts per thousand higher than usual in Baltica, only the values for the HICE remains within what is expected. Background values increase from 1.5 parts per thousand in the bottom of the core of the Boda Limestone up to 3 parts per thousand in the top of it. The HICE is identified in five of eight sections and the main peak falls according to inferred correlation within the Metabolograptus persculptus Biozone, at or close to the Hindella beds in the Upper Boda Member. The late Katian (Pirgu) age of Holorhynchus in the Siljan district is clear and its co-occurrence with the chitinozoan Belonechitina gamachiana in Estonia supports a Katian age for this zone. The base of the Ozarkodina hassi Biozone may occur within units B-C of the Upper Boda Member and in the upper part of the Loka Formation and most likely is correlated with the M. persculptus Biozone. The Hirnantia-Dalmanitina faunas reported from the lowermost part of the Loka Formation and units B-D of the Upper Boda Member seem to range through all the Hirnantian, but detailed morphological studies allow to distinguish an older (=extraordinarius) and a younger (=persculptus) fauna.

Tidskriftsartikel (refereegranskat)abstract
- The Lower Ordovician Bjørkasholmen Formation at Flagabro, Scania, southern Sweden, consists of a 0.8m thick succession of carbonates with three siliciclastic mudstones, 5, 1 and 100mm thick, intercalated in the central part of the unit. Carbonate and siliciclastic mudstone beds show both normal and inverse grading. The carbonates are mud-rich and subdivided into a mudstone, a wackestone and a packstone facies. Grain types in the carbonates are mostly shells and shell fragments of brachiopods and trilobites. The carbonate rocks are strongly bioturbated seen as in roundish burrows filled with mud and a clear cement; additionally, bioturbation is reflected in the random orientation of shells. The siliciclastic mudstones are subdivided into two facies; one contains large amounts of shells and is in part grain-supported, the other is matrix-dominated and laminated to massive. The succession reflects sedimentation on a low-inclined shelf equivalent to a mid-ramp to basinal setting. Most mud- and wackestones (facies 3 and 4) represent fair-weather sedimentation, and the intercalated wacke- and packstones (facies 4 and 5) represent concentration of shell debris during high-energy storm. The siliciclastic mudstones in the central part of the succession reflect deposition in a basinal setting. The entire BjOrkasholmen Formation at Flagabro is equivalent to a lowstand of third (?) order without a well-developed internal cyclicity and is in that respect similar to the Bjørkasholmen Formation of oland, but different from the age-equivalent Norwegian sections.

Competition in slow motion : the unusual case of benthic marine communities in the wake of the end-Permian mass extinction
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Changes of community structure in response to competition usually take place on timescales that are much too short to be visible in the geological record. Here we report the notable exception of a benthic marine community in the wake of the end-Permian mass extinction, which is associated with the microbial limestone facies of the earliest Triassic of South China. The newly reported fauna is well preserved and extraordinarily rich (30 benthic macroinvertebrate species, including the new species Astartella? stefaniae (Bivalvia) and Eucochlis obliquecostata (Gastropoda)) and stems from an environmentally stable setting providing favourable conditions for benthic organisms. Whereas changes in the taxonomic composition are negligible over the observed time interval of 10-100ka, three ecological stages are identified, in which relative abundances of initially rare species continuously increased at the cost of previously dominant species. Concomitant with the changes of dominant species is an increase in faunal evenness and heterogeneity. In the absence of both environmental and taxonomic changes, we attribute this pattern to the long-term effects of interspecific competition, which acted at an unusually slow pace because the number of competing species and potential immigrants was dramatically reduced by the end-Permian mass extinction. We suggest that these non-actualistic conditions led to decreased rates of niche differentiation and hence to the delayed rediversification of benthos that characterizes the aftermath of the greatest Phanerozoic mass extinction event. A hyperbolic diversification model is proposed, which accounts for the positive relationship between the intensity of interspecific competition and the rate of niche differentiation and resolves the conundrum of delayed rediversification at a time when niche space was largely vacated.

Towards a shared image. Supervision in artistic research as acts of collaborative knowledge creation

Bokkapitel (refereegranskat)abstract
- This chapter departs from the question: How can the supervision of artistic research in music influence and promote agency for PhD candidates? Supervision is seen in the context of on-going institutional change and discussed as encompassing the following aspects: (i) making the candidate pass, (ii) conducting artistic collaborations, (iii) evaluating artistic development and quality, and (iv) creating a safety zone. It is suggested that supervision can be a dynamic meeting point for the combination of these aspects and result in collaborative knowledge creation. This is a long-term, collective process that both requires and results in individual growth, group development and a continuous rethinking of institutional self-image.
