A nest cup out of moss, in which six great tit eggs are arranged in a little circle. In the middle of the eggs there is an iButton - a small thermometer device.

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.
www.uu.nl/en/organisat...
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.
