1. 11. Extinction, or the Extension of Life : Biology and History as Representation and Metaphor in Ted Chiang's "Seventy-Two Letters"

   University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Author : Sofia Jonsson; [2022]
   Keywords : Ted Chiang; Speculative Fiction; History of Ideas; Michel Foucault; Gillian Beer; Biology; History; Evolutionary Theory; Preformation; Literature; Metaphor; Representation; Darwin; Nineteenth Century;

   Abstract : This paper explores Ted Chiang's novella "Seventy-Two Letters" and the way in which it combines genres, scientific and historical ideas in an effort to examine topics about life and creation. The combinations result in an intriguing representation of a history which is then made different and where Chiang can creatively challenge past ideas. READ MORE

3. 12. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Simon Hannus; [2021]
   Keywords : Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

   Abstract : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

4. 13. Fine-scale recombination landscape in the wood white butterfly Leptidea sinapis

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Aleix Palahí i Torres; [2021]
   Keywords : recombination; butterfly; Leptidea; population;

   Abstract : Recombination is a genetic process of extreme importance in evolutionary biology. It creates novel haplotypes and breaks down existing ones, and can affect the levels of genetic diversity and the efficacy of selection. It also plays an important role in the evolution of sex chromosomes and the divergence process leading to speciation. READ MORE

5. 14. Automated pipeline for processing fluorescence calcium imaging microscopy data and electrophysiological measurements from 3D brain organoids

   University essay from Lunds universitet/Examensarbeten i bioinformatik

   Author : Mattis Knulst; [2021]
   Keywords : Biology and Life Sciences;

   Abstract : Motivation: 3D brain organoids are biological models of human brain development from which a rich body of data can be extracted that allows for insights about neuronal dynamics. Several tools, such as fluorescence calcium imaging microscopy and electrophysiological recordings are being used to assess how 3D brain organoid dynamics recapitulate what is known from the human brain.

6. 15. Effect of ascertainment bias on calculations of sex-biased admixture in Southern Africa

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Ragnheidur Diljá Ásmundsdóttir; [2021]
   Keywords : Evolutionary Biology; Population Genomics; Human Evolution;

   Abstract : Southern African populations harbour great genetic diversity enhanced by  population migration to the area in the last two millennia. Africa is perhaps the least studied continent in regards to population genetics and is often underrepresented in global studies. READ MORE
