Libor Zàvorka: warming shrinks juvenile Atlantic salmon by decreasing their fatty acids

In this blog, postdoc Libor Zàvorka from Inter-University Centre for Aquatic Ecosystem Research (Lunz) discuss his research on climate change effects on salmon diet, shows the relevance of physiological changes in ecosystems and presents his long record as fish catcher.  About the paper The big question: how does variability in content of essential fatty acids in natural prey drive development and evolution of brain and … Continue reading Libor Zàvorka: warming shrinks juvenile Atlantic salmon by decreasing their fatty acids

Molly Roberts: A network of threads and perspectives, energetic cost of mussel attachment

Emily “Molly” Roberts, postdoctoral fellow at Claremont McKenna College, presents her recent work ‘Resource allocation to a structural biomaterial: induced production of byssal threads decreases growth of a marine mussel, Mytilus trossulus’ where she and her colleagues tested the trade-off between survival and growth of mussels. About the paper This paper is about the energetic ‘investment’ that mussels make to stay anchored to their habitat. … Continue reading Molly Roberts: A network of threads and perspectives, energetic cost of mussel attachment

Louise S. Nørgaard: Energetics, population density and pathogen performance

Louise S. Nørgaard is currently working as a Research Fellow at the centre of Geometric Biology at Monash University, Melbourne. In this Insight, she talks about her recent publication in Functional Ecology, ‘Energetic scaling across different host densities and its consequences for pathogen proliferation’. About the paper What’s your paper about? Using the freshwater Daphnia magna and its gram-positive bacteria Pasteuria ramosa, we explore how … Continue reading Louise S.
