Allan Ecology Group at INTECOL2022

After a few years of postponements and delays due to the Covid pandemic, INTECOL2022 was finally held in Geneva in September, bringing together ecologists from across the globe to share research on applied and fundamental questions in many areas of ecology. This breadth of research was demonstrated in the 50 sessions held at INTECOL including topics such as biodiversity, ecological mechanisms across scales, climate change, restoration, plant-enemy interactions and more.

It was great to be able to attend an in-person conference again! INTECOL 2022 had some really interesting talks, I especially enjoyed the theoretical discussions with the plenary talk by Peter Chesson and also the talk on eco-evolutionary effects on species coexistence by Vasco Lepori. Discussions around experimental results were also enriching, especially the impressive presentation from Zoe Xirocostas on how introduced plant change their interactions with enemies in their new ecosystem. – Caroline

I really enjoyed having a chance meeting and talking to many people at the INTECOL 2022 conference who are working in different aspects of ecology. The talks in the “Plant-enemy interactions in a changing world” and “Land use and biodiversity” sections were the ones I liked the most and therefore it would be difficult to pick one or two. It was very nice to not only share our work but also have a social life with other people in different countries called pandemic PhD. Thu Zar Nwe

For me, the best experience was the sheer wealth of inspiration, the opportunity to meet so many creative and enthusiastic but also busy researchers, in an environment where we all finally had time to share. I can’t remember how many times I thought “Ecology is just great!” I was especially deeply impressed by the work of several female early-career scientists, so many great role models for the future! The only downer was the question of how many colleagues stayed away from Switzerland for financial reasons. Wishing them the same feeling of being part of a large research community. – Noëlle Schenk

The Allan Ecology group was very involved in the conference including the organisation of a session by Eric, Anne, Gemma and Suz titled Plant Enemy Interactions in a Changing World. This session drew a number of big names in plant-enemy ecology as well as many emerging early and middle career researchers. All in all, it was a really interesting session to attend with new information, methods, data and a lot of interesting discussion. We finished the session with a dinner and drinks with all the speakers from the session which was a great time to keep chatting about ecology after many years of not seeing our international colleagues in person! You can see a thread that summarises all of the talks from this session on Suz’s twitter, complete with pictures of all the fantastic speakers!

Our team also contributed 5 talks to the conference. Eric and Anne presented an overview on the current state of knowledge of plant-enemy interactions and what the next big questions in this important ecological area may be. Suz presented preliminary results from the BugNet project in the same session (Plant Enemy Interactions in a Changing World) where many BugNet collaborators were in attendance and could see their data contributing to this exciting global study.

Thu Zar presented research from her PhD on how collembola communities and their functioning eg. mandible traits are driven by variable factors, which are altered by nitrogen addition directly and indirectly. Caroline also presented research from her PhD on how nitrogen and fungicide addition impact plant species competition networks, a study using competition matrices parametrized with data sampled on the PaNDiv experiment. And finally, Noëlle gave an excellent talk on her research from the Biodiversity Exploratories on how beta-diversity of multiple trophic groups and land-use intensity drive different grassland locations to provide distinct sets of ecosystem functions.

The group also had time to attend field trips at the conference including an excursion to the mountain pasture of Chênex (Salève, France).
