- Although once popular prior to the last century, the aquaculture of crucian carp Carassius carassius (L. 1758) in Sweden gradually fell from favour. This is the first genetic comparison of crucian carp from historic man-made ponds in the Scandinavian Peninsula. The aim was to identify old populations without admixture and to compare the relationship of pond populations from different provinces in Sweden. In total, nine microsatellite loci from 234 individuals from 20 locations in varied parts of Sweden were analysed. The genetic distances of crucian carp populations indicated that the populations in the southernmost province of Sweden, Scania, shared a common history. A pond population in the province Småland also showed a common inheritance with this group. In the province Uppland, further north in Sweden, the population genetic distances suggested a much more complex history of crucian carp distributions in the ponds. The data showed that there are some ponds with potentially old populations without admixture, but also that several ponds might have been stocked with fish from many sources.

Professor Ingvar Kärnfelt - a birthday tribute

- On 19 July 2009 Ingvar Kärnefelt celebrated his 65th birthday. This could have meant that we, his former students, would be celebrating him in his retirement from his position as head of the Biological Museums at Lund University. We are grateful that this is not the case, as Ingvar will carry on, probably for at least one or two more years. Instead, we celebrate Ingvar because he is the main reason for all of us having studied lichenology in Lund. This special issue of The Lichenologist is dedicated to him as a birthday tribute in honour of his long and fruitful lichenological career. The main authors of all the papers in this issue are former students of Ingvar. For several of us he has not only acted as supervisor but later also as the director of the Botanical Museum where we meet him in our daily work.

Decline in lichen biodiversity on oak trunks due to urbanization
- 2014

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Biodiversity often suffers from urbanization. In the present study, we focused on how the duration of urbanization affects the richness of 17 epiphytic lichen species and their cover on large oaks in urban environments in a city of 100 000 inhabitants in southeast Sweden. We also surveyed trees in adjacent rural areas, selected to have similar distributions of tree trunk circumference and surrounding oak density (within 300 m). Lichen richness and cover were lower on urban trees compared to rural trees. Furthermore, richness and cover decreased with the length of time that urban trees had been surrounded by houses. Most of the species that were analysed demonstrated a decline in occurrence with respect to the duration of housing development. The reduction in the probability of occurrence varied from 60% (Calicium viride, Evernia prunastri), 80% (Chrysothrix candelaris) to 90% (Ramalina spp.) during the considered 160-year period of urbanization. Therefore, even if valuable trees survive over the course of development, their lichen biota is likely to become depleted over time. © 2014 The Authors.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Knowledge of spore to spore generation time is extremely important for several reasons. As it is the shortest generation time, it indicates the maximum nucleotide substitution rate over time and provides a rate limit for the evolution of a species. In population genetics most calculations involving time use ‘generations’ as the unit of measurement and in order to convert these ‘generations’ into ‘years’, knowledge of generation time is needed but rarely available. Knowledge of generation time may also be essential for conservation purposes and assessments of migration history. This knowledge also makes it possible to estimate both the age of a population and also to determine to what extent a population represents the genetic diversity of a species (Rosenberg & Nordborg 2002). In this paper we present a method for assessing generation length for lichens using Cliostomum corrugatum (Ach.) Fr. as an example. This lichen was selected for investigation because it is restricted to forests with long temporal continuity (Lättman et al. 2009) and information on generation time is essential to estimate the rate of dispersal at the landscape level.

- A practical and modular approach to obtain a diverse set of 14-membered macrocyclic compounds from carbohydrates is developed that utilizes functional groups at C-1 and C-5. The evaluation of this toolbox in various zebrafish assays led to the identification of 2.7f as an antianglogenesis agent.
