Welcome to EvE!
Research and teaching in EvE focus on how individuals, populations and communities interact and cope with environmental variability. We synergistically address a wide variety of perspectives and methodologies in evolutionary ecology, including plant and animal ecology, integrative botany and zoology, ecotoxicology, and conservation.
Defence: Franziska Willems
06.07.2021 ► Franziska Willems, EVEREST student in Plant Evolutionary Ecology, and supervised by Prof. Dr. Oliver Bossdorf and Dr. Niek Scheepens (now a professor at the Goethe-University of Frankfurt a. M.), has successfully defended her PhD thesis on the effects of global change on plant phenology. Part of her PhD work has been published in the New Phytologist and Ecological Applications.
Publication: Ovipositor of the braconid wasp Habrobracon hebetor: structural and functional aspects
28.06.2021 ► Michael Csader et al. (Journal of Hymenoptera Research) from the ‘Evolutionary Biology of Invertebrates’ research group investigated the ovipositor of a parasitoid braconid wasp in detail. They have combined light- and electron-microscopic techniques with 3D reconstructions, described all inherent cuticular structures and examine their mechanics and function. This work furthers our understanding of a putative key feature in the evolution of braconids and parasitoid wasps in general.
Public relations: Farmland conservation project at Berlin "Woche der Umwelt"
07.06.2021 ► Invited by the German Federal Environmental Foundation (DBU) and Federal President Steinmeier, the EvE institute now presents ongoing research on farmland bird conservation during the environmental fair "Woche der Umwelt" in Berlin. The project develops tools to reconcile modern agricultural techniques with the nesting needs of endangered bird species that breed in hay meadows and cereal fields. Details via attempto online and youtube.
Publication: Forest management and plant phenology
25.05.2021 ► Intensive forest mangement also changes the phenology of understorey plants. A new study from the Plant Evolutionary Ecology group published in Ecological Applications (first author: Franziska Willems) finds that in intensively managed forests the flowering of woodland anemones and other early-flowering species is on average delayed by two weeks compared to more natural forests.
Publication: Gastropods and the Colburn analogy
21.05.2021 ► In an interdisciplinary cooperation between the Animal Physiological Ecology Group, the Faculty of Engineering of Esslingen U for Appl Sci and the Institute of Applied Physics, microstructural investigations of the vascular system in the helicoid lung in combination with fluidic principles allowed the calculation and modelling of hemolymph and oxygen transport, and revealed construction-related physiological limitations in land snails (PLoS ONE).
Defence: Anna Kirschbaum
01.04.2021 ► Anna Kirschbaum, EVEREST student in Plant Evolutionary Ecology, has now successfully defended her PhD project on the "evolution of plant phenotypic plasticity in response to grassland management". During her PhD project, Anna was supervised by Dr. Niek Scheepens (now a professor at the Goethe-University of Frankfurt a. M.). The first paper that was generated from her work has now been issued in the Journal of Plant Ecology.
Publication: Combined effects of climate change and habitat destruction in a rainforest songbird
02.02.2021 ► Building on previous work, a new study co-authored by Henri Thomassen (Comparative Zoology) proposes a framework to estimate the “genetic vulnerability” of local populations to the combined impacts of climate change and other habitat modifications. (Evol. Appl.)
Publication: Fish without fear
21.01.2021 ► Following their findings on biochemical and histological effects of the widely used psychotropic drug venlafaxine in trout (Env. Sci. Europe), Michael Ziegler et al. (Animal Physiological Ecology) demonstrated that even small amounts of this anxiety reliever in the range of environmentally relevant concentrations in water make fish significantly more 'relaxed' and careless (Frontiers Env. Sci.).
Publication: Thermal selection in land snails
15.01.2021 ► Field experiments simulating environmental warming revealed strong selection against pigmented morphs in a widely distributed species of land snails. An international consortium led by EvE scientists provided evidence for thermal selection across multiple levels of biological organisation (Ecology and Evolution).
Defence: Julia Geue
18.12.2020 ► Julia Geue, EVEREST student in Comparative Zoology, has now successfully defended her PhD project. Julia has investigated Landscape Genomics as a tool in conservation prioritization. Her work generated several publications, including papers in Wiley's Ecology and Evolution.
Conference: Meeting StEvE 2020 went online
24.11.2020 ► For the first time, the Tübingen Meeting of Students in Evolution and Ecology (Meeting StEvE) has now been held as an entirely web-based remote conference. More than 100 students and faculty from Tübingen and beyond joined an exciting opening lecture by Mark Moore. He illustrated how inferences from stone-flaking experiments on the cognitive abilities of early humans may suffer from biased assumptions. Participants then engaged in lively discussions with 15 EVEREST students, who gave stimulating oral or poster presentations about their current PhD projects. Prizes for the best poster went to Frank Reis (microbiome ecology), and for the best talks to Julia Geue (surrogacy in conservation prioritization), Franziska Koch (stability rules for species networks), and Sophie Habinger (paleoecology of pongin primates).
The PhD students in Early Prehistory and Quaternary Ecology have made this a highly professional event! Thanks to William Snyder, Eleonora Gargani, Li Li, Diana Marcazzan, Alba Motes Rodrigo, and Jordy Orellana Figueroa.
Publication: Wavelength-specific heating of snails
07.08.2020 ► Based on the work conducted within a course of the MSc programme (Advanced Animal Ecophysiology), Tatjana Tull and Danina Schmidt jointly have published their results on the role of ambient wavelength, shell size and pigmentation intensity in the heating of individuals of a Mediterranean land snail species (Journal of Molluscan Studies).
State Competition "Baden-Württemberg blooms"
31.07.2020 ► The "Colourful Meadow" initiative is among the winners of the state competition Baden-Württemberg blooms in the category "Other actors".
Publication: Insect compound eyes inspired novel adjustable technical optics
24.07.2020 ► Together with researchers from the Vienna University of Technology, Manfred Drack (Evolutionary Biology of Invertebrates) developed a 3D printed prototype for a new optical device. Based on the advantages of compound eyes, an additional technical zooming feature was introduced that cannot be found in the biological system. Furthermore, an adjustable field of view per 'pixel' was implemented (Frontiers in Materials).
