Elina ViinamäkiResearch engineer
About me
I work as a laboratory manager and research engineer at ACESx; Exposure and Effects.
I have main responsibility for our living cultures which include small crustaceans, green microalgae and chromists. I am involved in various student projects where I help set up experiments and provide guidance in lab work. I also make sure that the lab equipment work properly and that they get serviced.
I'm responsible for our field work; the environmental monitoring sampling of amphipods in the bottom sediments of the Baltic Sea.
Within the environmental monitoring group I am currently training in embryo analysis of amphipod crustaceans, especially Monoporeia.
Another interest is molecular biology, I have worked a lot with extraction of DNA/RNA, amplification and preparation for sequencing.
Additional areas of interest are microscopy, eDNA, Bioinformatics and animals.
I have a Swedish master's degree in Biology and a MSc in Marine Biology.
I have done two major interesting research projects; one via Department of Zoology and the Swedish Museum of Natural History where I combined morphological and molecular methods to distinguish and taxonomically determine species of rays. In the second work at Department of Ecology, Environment and Plant Sciences, I received a scholarship from SIDA to collect plankton samples in different aquatic habitats on Zanzibar. These plankton samples were analyzed by me at SU and I used molecular methods to identify fish larvae. This was to map how different fish species use different habitats as nurseries.

Population genetics of the hound needlefish Tylosurus crocodilus (Belonidae) indicate high connectivity in Tanzanian coastal waters

ArticleRead more about Population genetics of the hound needlefish Tylosurus crocodilus (Belonidae) indicate high connectivity in Tanzanian coastal watersThe hound needlefish Tylosurus crocodilus (Belonidae) is a highly demanded fish in the local markets of Tanzania, but the growing coastal population threatens its sustainability. As belonids are highly migratory fishes utilising various parts of the seascape, increased fishing pressure may disrupt connectivity patterns on different spatiotemporal scales and disaggregate populations. Using the COI gene, this study assessed the genetic population structure, connectivity patterns, and historical demography of T. crocodilus collected in seven sites spread along Tanzanian coastal waters. Results showed fourteen haplotypes with low overall nucleotide and haplotype diversity. Pairwise FST comparisons revealed no significant differences among the sampled sites, except for the northernmost site (Tanga) and an island in the south (Songosongo). Analysis of molecular variance (AMOVA) revealed a non-significant genetic structure among populations (FST = 0.01782), suggesting the fishery across Tanzanian waters exploits the same population. Moreover, there was no correlative relationship between genetic and pairwise geographic distances, rejecting the isolation by distance hypothesis. However, neutrality tests and mismatch distribution analysis revealed that recent demographic expansion might exist. Empirical evidence of panmixia suggests high genetic connectivity. In combination with low genetic diversity, management should be directed to actions that prevent genetic diversity loss and the effect of genetic drift on populations.
