Abstract submission may be closed, but it is not too late to sign up to attend the NLSEB Annual meeting. Great plenary talks and a great line up of talks and posters. And thanks to our sponsors NWO and @isme-microbes.bsky.social for helping making this meeting possible.
Figure 1 Both (2026): (a) Correlation between the annual average hatching date and the date of the caterpillar peak (open dots are experimental years: 2015 (intermediate in caterpillar peak date of the three experimental years), 2021 (latest caterpillar peak date) and 2022 (earliest caterpillar peak date), (b) the interval between arrival and laying in response to the caterpillar peak, (c) the annual strength of selection on laying date, measured as the linear slope of standardized laying date on relative fitness (measured as the number of locally recruiting offspring per female) (open dots are experimental years: 2015, 2021 and 2022), (d) example of the correlation between individual interval between arrival and laying in response to variation in arrival date for two experimental years: blue triangles: 2021, a cold spring, and red dots: 2022, a relatively warm spring.

Figure 2 Radchuk (2026): A selection of studied species is shown, with each inset giving information for that species on its generation time (T, in years; also depicted by the black bar next to it), its diet (carnivore: C, herbivore: H, and omnivore: O) and whether the species is a migrant (M) or a resident (R). The inset shows the number of studies per taxon and trait category.

Well done @aureliastrauss.bsky.social Glad this is out now.
Thanks Viktoriia for leading this excellent project.
🚨🚨🚨 Field Assistant positions - four of them!! - working with the long-term Wytham project this coming spring. Details below. Previous year's field team - come and join us! Details below ⬇️
The University of Vienna awards at least 20 four-year and full-time (40h/week) postdoctoral positions to outstanding female scientists in natural sciences, life sciences, and economics.
Restoring nature and reversing biodiversity loss are urgent societal challenges. Utrecht University invites applications for an Assistant Professor in Wildlife Ecology and Nature Restoration. In this role, you contribute to help solve these challenges through research and education by linking fundamental wildlife ecology to biodiversity recovery and nature restoration. As an Assistant Professor, you will join a young, enthusiastic team that is eager to make an impact. You will help strengthen the team’s mission to connect fundamental wildlife ecology with the challenges of nature restoration in human-dominated multifunctional forest landscapes, especially in north-western Europe. Your research will focus on restoration-relevant themes, such as wildlife responses to anthropogenic change, the effectiveness of conservation interventions, and the contribution of wildlife to biodiversity recovery and nature restoration. Close collaboration with colleagues within and beyond Utrecht University is an important part of this role, as well as building sustainable partnerships with conservation practitioners and policymakers. You will combine fieldwork, experiments and biomonitoring (e.g. using sensor technologies) with laboratory, statistical and theoretical approaches. There is ample opportunity to initiate research projects and to acquire funding. In education, you will teach in the Biology programs, develop and coordinate a new course, and supervise research projects of BSc, MSc and PhD students.
Are you a PhD-level #wildlife ecologist committed to research and education for #biodiversity and nature restoration?
Our group at @utrechtuniversity.bsky.social has a #vacancy for an assistant professor!
Deadline for applications is February 19.
Please spread the word.

PhD candidate #vacancy alert:
Insect species that overwinter as eggs are particularly vulnerable to climate change. We are looking for a PhD candidate to collect more data to predict whether these insects can adapt to climate change.
