Seminar

On 25 October 2022 at 13.15 CET over zoom, Koh Hasegawa will be giving a talk about the ecological effects of invasive salmonids and interactions between hatchery-reared and wild fish in Japan.

Koh Hasegawa is a Fish Conservation Ecologist working with the Salmon Research Department of the Japan Fisheries Research and Education Agency. Koh in his talk will answer questions about what brown trout do in the urban streams in Sapporo and whether it is a good idea or not to let hatchery-reared and wild population of salmon mix. You are welcome to join this seminar over zoom on Tuesday 25 October at 13:15 CET via https://kau-se.zoom.us/my/kaubiology

On 13 September, Aafke Schipper will be giving a seminar with the title Biodiversity modelling for policy support to our department. Her work centers on the development and application of large-scale biodiversity assessment models to understand past and future effects of anthropogenic activity on biodiversity globally, and she works on a wide range of taxa to do so.

As an assistant professor at Radboud University and researcher at the Netherlands Environmental Assessment Agency, Aafke also informs policymakers on both the national and international level. Read about some of her current and future work on https://www.globio.info/ and https://www.ru.nl/en/research/research-news/vidi-grants-for-research-into-freshwater-fish-geometry-our-sense-of-smell-and-more, and join us for the first autumn seminar on Tuesday 12 September at 13:15 CEST via https://kau-se.zoom.us/my/kaubiology!

Regina Lindborg, a Professor from Stockholm University will be giving a seminar entitled Biodiversity and ecosystem services from grasslands – towards a more sustainable agriculture on Tuesday 7 June 2022 at 13.15 CEST over zoom https://kau-se.zoom.us/my/kaubiology.

Regina’s research focuses on the conservation of biodiversity, with a special focus on natural pastures, and how to combine the management of ecosystem services and the conservation of biodiversity with sustainable food production in the agricultural landscape. Regina works mainly with issues that are linked to landscape ecology and processes that concern large space and time scales such as changes in land use and the effects of climate change. Several of Regina’s studies are done in interdisciplinary collaboration with researchers from other disciplines, such as economics and cultural geography.

Daniel Nyqvist from Politecnico di Torino will be giving a seminar entitled Fish movement and behavior in industrial waters – electromagnetism, noise and ecohydraulics on Tuesday 31 May 2022 at 13.15 CEST over zoom https://kau-se.zoom.us/my/kaubiology.

Daniel’s current research focuses on fish behavior and ecology in regulated rivers. Also, he is interested in movement ecology, effects of acoustic noise and electromagnetism on fish behavior, conservation, and the connections between ecology and socioeconomics.

You are welcome to join this seminar.

Jason Lee Anders, a Postdoc researcher from CEES, Oslo will be giving a seminar entitled “Effects of dietary shift and intestinal helminths on the gut microbiota of two sympatric rodents in urban environments“. Cities are among the most extreme forms of anthropogenic ecosystem modification and urbanization processes that exert profound effects on animal populations through multiple ecological pathways. Understanding how urbanization alters the gut microbiome of wildlife is essential as it plays a pivotal role in health and development. The focus of this project is to understand how the gut microbiota of two sympatric species of rodents, the omnivorous large Japanese field mouse (Apodemus speciosus) and the relatively more herbivorous grey red-backed vole (Myodes rufocanus), is altered within urban ecosystems and what factors may be affecting those changes. Both species exhibited an expanded dietary niche width within the urban areas potentially attributable to novel anthropogenic foods and altered resource availability. We detected a dietary shift in which urban A. speciosus consumed more terrestrial animal protein and M. rufocanus more plant leaves and stems. These changes in resource use may be associated with an altered gut microbial community structure such as an increased abundance of the presumably probiotic Lactobacillus in the small intestine of urban A. speciosus. While urbanization negatively impacted several intestinal helminth species (i.e. lower prevalence and abundance), the cosmopolitan nematode Heterakis spumosa may be important for maintaining high gut microbial alpha diversity. Furthermore, it may promote lower relative abundance of the potentially pathogenic Helicobacter in the lower gastrointestinal tract of urban M. rufocanus. Together, these results suggest that even taxonomically similar species may exhibit divergent responses to urbanization with consequences for the gut microbiota and broader ecological interactions.

Jason’s seminar will be streamed live on zoom through https://kau-se.zoom.us/my/kaubiology on Tuesday 24 May at 13.15 CEST.

Dr. Tom Staveley, an aquatic ecologist and a researcher from SLU Aqua, Sweden will be giving a talk entitled Coastal seascapes and seagrass ecosystems on Tuesday 10 May at 13.15 CET over zoom. Tom’s research interest is in marine landscape ecology concepts and applications, particularly fish ecological connectivity using methods such as acoustic telemetry. You can visit Tom’s page to read more about his research interest and publications.

Road verges act as important refuges for grassland species since the areas of semi-natural grassland have declined during the last century. However, as linear habitats, road verges increase connectivity in fragmented landscapes, which also makes them prone to colonization by non-native species. This is currently seen as the greatest threat to species-rich road verges. The invasive Garden Lupine is commonly found in road verges where it alters competitive interactions, reduces native populations, and even causes extinctions of native species. 

This project is funded by The Swedish Transport Administration (Trafikverket) and the aim is to improve ecosystem functions and services of species-rich road verges and green infrastructure through evidence-based control and monitoring of Garden Lupine at the landscape scale.

During this seminar, I’m going to introduce the background for the project, and talk about what has been done and what I am planning to do in the next years.

The seminar will be streamed live over zoom on Tuesday 26th April at 13.15 CET. The zoom link for the seminar is https://kau-se.zoom.us/my/kaubiology. You are welcome

Dr. Navinder Singh, a researcher at SLU Silva will be giving a talk about Movement ecology on Tuesday XX th April at 13.15 CET over zoom.
