Evolutionary responses of energy metabolism, development, and reproduction to artificial selection for increasing heat tolerance in Drosophila subobscura
<p><span>Adaptation to warming conditions involves increased heat tolerance and metabolic changes to reduce maintenance costs and maximize biological functions close to fitness. Evidence shows that energy metabolism evolves in response to warming conditions, but we know little about how heat stress intensity determines the evolutionary responses of metabolism and life history traits. Here, we evaluated the evolutionary responses of energy metabolism and life-history traits to artificial selection for increasing heat tolerance in Drosophila subobscura, using two protocols to measure and select heat tolerance: slow and fast ramping protocols. We found that the increase in heat tolerance was associated with reduced activity of the enzymes involved in the glucose-6-phosphate branchpoint, but no changes in the metabolic rate in selected lines. We also found that the evolution of increased heat tolerance increased the early fecundity in selected lines and increased the egg-to-adult viability only in the slow-ramping selected lines. This work shows heat tolerance can evolve under different thermal scenarios but with different evolutionary outcomes on associated traits depending on the heat stress intensity. Therefore, spatial and temporal variability of thermal stress intensity should be taken into account to understand and predict the adaptive response to ongoing and future climatic conditions.</span></p>

Evidence for personality development: juvenile red knots vary more in diet and exploratory behaviour than adults
<p>Evidence is accumulating that foraging behaviour and diet link to personality traits, yet little is known about how these associations emerge during development. It is expected that behaviour becomes more consistent with age, and thus experience. We compared exploratory behaviour and diet variances of juvenile and adult red knots shortly after migration to intertidal mudflats from tundra breeding grounds. By identifying the timing of the switch from tundra to marine isotopic signatures, we were also able to ask whether juveniles that arrived earlier were more consistent in exploration behaviour. We found that juveniles had a more diverse diet than adults, and that juveniles were less repeatable in exploration than adults. While juveniles had larger within-individual variance, among-individual variance was similar between age groups. Juveniles that arrived earlier did not vary more in exploratory behaviour compared to those that arrived later, suggesting that consistency in exploration was developed over a longer period than the four weeks of our study. Our findings suggests that after initial exploration of a novel habitat, juveniles likely try-out foraging techniques which later develop into consistent behaviours that differ among individuals. This study illuminates how personality can develop with experience in a free-living animal.</p>

Dataset supporting publication: "Geofit: Experimental Investigations and Numerical Validation of Shallow Spiral Collectors as a Basis for Development of a Design Tool for Geothermal Retrofitting of Existing Buildings"
<p>Dataset supporting publication: “Geofit: Experimental Investigations and Numerical Validation of Shallow Spiral Collectors as a Basis for Development of a Design Tool for Geothermal Retrofitting of Existing Buildings” (publication available in <a href="https://zenodo.org/record/7273966#.Y2JgBnbMJPY">GEOFIT Zenodo</a>)</p> <p>The H2020 GEOFIT (grant no. 792210) project will implement and demonstrate easy-to-install and economical geothermal systems in combination with heat pumps for energy-efficient building retrofits at five pilot sites across Europe - a historic building (ITA), a school (ESP), an indoor swimming pool (IRL), an office building (FRA) and a single-family house (IRL) (GEOFIT,2018). Heat pump tests and experimental laboratory tests with shallow geothermal heat collector types are carried out in climate chambers at the AIT. Material data of different soil types are determined in the thermophysics laboratory. Furthermore, CFD simulations of the conducted experiments are calculated with ANSYS Fluent. All this provides data and know-how for the development of a design tool for ground collector configurations such as helices and slinky loops, which are particularly relevant for building retrofits in GEOFIT. Experimental work focused on near-surface spiral geothermal heat exchanger configurations that can be installed at a maximum depth of five metres. Real-scale experiments were carried out for vertically oriented spiral collectors (helix) in real soil. One objective was to develop a measurement concept in the laboratory environment to create the framework for a reliable database. This database is used as a basis for the further development or new development of engineering design tools. Distributed resistance temperature sensors and a fibre-optic temperature measurement system (DTS) were used. The moisture content of the soil was recorded using soil moisture sensors. A heat flow was conditioned by means of a helix shaped electric heating cable in a 1m³ cuboid soil container. The measurements were carried out in a climate chamber at a defined constant temperature of 10 °C. The evaluation of the transient response behaviour is spatially resolved. This results in coordinate-related temperature points, which describe temperature gradients in all axes of the container over time. Three different types of soil were investigated. The temperature behaviour of humus soil, sand and a mixture of these was investigated experimentally in smaller experiments and the material data such as heat capacity, thermal conductivity and density were determined thermophysically in the laboratory. Based on this data, a CFD model was developed which can be used to modify the geometry parameters of the helix.</p>
Glue genes are subjected to diverse selective forces in Drosophila during Drosophila development
<p>Molecular evolutionary studies usually focus on genes with clear roles in adult fitness or on developmental genes expressed at multiple time points during the life of the organism. Here, we examine the evolutionary dynamics of Drosophila glue genes, a set of eight genes tasked with a singular primary function during a specific developmental stage: the production of glue that allows animal pupa to attach to a substrate for several days during metamorphosis. Using phenotypic assays and available data from transcriptomics, PacBio genomes, and genetic variation from global populations, we explore the selective forces acting on the glue genes within the cosmopolitan <i>D. melanogaster</i> species and its five closely related species, <i>D. simulans</i>, <i>D. sechellia</i>, <i>D. mauritiana</i>, <i>D. yakuba</i>, and <i>D. teissieri</i>. We observe a three-fold difference in glue adhesion between the least and the most adhesive <i>D. melanogaster</i> strain, indicating a strong genetic component to phenotypic variation. These eight glue genes are among the most highly expressed genes in salivary glands yet they display no notable codon bias. New copies of <i>Sgs3</i> and <i>Sgs7 </i>are found in <i>D. yakuba </i>and<i> D. teissieri</i> with the <i>Sgs3</i> coding sequence evolving rapidly after duplication in the <i>D. yakuba</i> branch. Multiple sites along the various glue genes appear to be constrained. Our population genetics analysis in <i>D. melanogaster</i> suggests signs of local adaptive evolution for <i>Sgs3</i>, <i>Sgs5</i> and <i>Sgs5bis</i> and traces of recent selection for <i>Sgs1</i>, <i>Sgs3</i>, <i>Sgs7 </i>and<i> Sgs8</i>. Our work shows that stage-specific genes can be subjected to various dynamic evolutionary forces.</p>
