A good fellowship application takes time to craft, so if you are thinking of coming to the UK and are interested in climate change effects on insect reproduction - including different life stages, eggs, micropyles, imaging, microscopy, thermal limits, ecological physiology, plants and microclimates and more - now is the time to think about it! There are different schemes to consider, depending on eligibility criteria:

Amazing news, my international exchange project to work with Sylvain Pincebourde (CNRS, France) was funded in May 2023! Sylvain and I have started working on linking microclimate (his expertise) and butterfly fertility (me). As a start, Sylvain visited Lincoln in June 2023 and we trialled two different thermal imaging cameras to measure temperature on wild and domesticated cabbages as well as eggs, caterpillars and pupae of the large white butterfly, Pieris brassicae. The wild black mustard, Brassica nigra, plants came from seeds that Nina Fatouros, Wageningen University, shared with me, while we grew kale (Brassica oleracea spp.) from organic seeds. The two thermal imaging cameras (FLIR E54 and FLIR T540) worked well, with the FLIR T540 comfortably outperforming the FLIR E54. No surprise there, as the price tag of the FLIR T540 is almost double that of the FLIR E54! The good news is that we can pick out the temperature differences across the leaves. This work was also done thanks to Teun's efforts - Teun is my summer Erasmus research intern for 2023. I look forward to developing this collaboration over the course of the next few years. It all started with an email in late August 2022. I wrote to Nina Fatouros at Wageningen University and Research (WUR), to ask her for some images (SEMs) of Pieris brassicae eggs. Over a few brief email exchanges, we discovered that we both shared an interest on insect eggs, and that we could learn from each other's different angles (mine on the evolution of reproductive traits, Nina's on plant-insect interactions). Nina invited me to apply for a Visiting Scientist Fellowship at WUR and then fast forward to 30th January 2023, I found myself on a train crossing the Channel heading for Wageningen, the Netharlands. I spent four intense (and fun) weeks at the Biosystematics Group, WUR. Nina, her PhD student Liana Greenberg, and I, drafted some hypotheses on latitudinal and climatic gradients effects on eggs of populations of Pieris spp. Nina and Liana have collected Pieris napi from across Europe, from Wageningen to Spain. Nina also has two stable populations of Pieris rapae and brassicae, which she has kept in the lab for a number of generations. I then spent several days in the company of Marcel Giesbers, a very knowledgeable SEM technician, to image Pieris eggs using Cryo SEM, which was a lot of fun (oh, and talking of Dutch cheeses with Marcel...). I have learnt a lot about plant-insect interactions (and dusted off my two botany exams taken decades ago), started a collaboration with an amazing colleague, and visited the Netherlands for the first time! I was made to feel at home by every member of the Biosystematics group, and I am indebted to Nina, Klaas, Eric, Liana, Wilma, Marcel, Patrick, Jordy, and everyone else at WUR + WEES for inviting me to give a talk. I really hope to be able to come back soon. The harvest mouse, aptly named Micromys minutus, the minute mouse, is Britain's smallest rodent and also one of the most understudied. Before Ellie's started her Masters by Research supervised by Carl Soulsbury and I, the last comprehensive review of its status and distribution in Britain was chiefly the one by Stephen Harris in 1979 (although later works do exist).
Ellie set out to map out the distribution of the harvest mouse in Lincolnshire, a primarily agricultural county and one of the largest. In collaboration with the Lincolnshire Wildlife Trust, Ellie spent a very long time dissecting owl pellets and Longworth trapping to provide a current snapshot and compare it to previous records. The good news is that harvest mice appear to have persisted in the county. To help inform conservation action, Ellie also analysed the co-occurrence of harvest mice and other small mammals and various environmental landscape features. Finally, she used population viability analysis to assess the minimum population size and habitat area required for population viability, as well as overall population resilience. Ellie's work has been featured by the newsletter of the Lincolnshire Wildlife Trust, the bulletin of the Lincolnshire Naturalist Union and the 'Student of the month' highlight of the Mammal Society. Congratulations to Ellie! |
