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.

Fig. 2. Maps of nocturnal bird migration across the Netherlands in spring and autumn, with the 100 km radius circles of the weather radars enclosing the onshore study area. Colors represent seasonal migration passage, converted from the original bird densities. Shaded areas mark grid cells for which over 25% of the input data, prior to filtering, were impacted by ground clutter. Migration passage in these regions may be compromised in either direction: overestimated due to remaining clutter artifacts or underestimated where terrain features partially obstruct the radar’s lower scanning angles.
Fig. 1. Flight altitude distributions (in m above sea level (asl)) of nocturnal bird migration for both Dutch weather radars at a coastal Den Helder and inland site Herwijnen. Bar length denotes the proportion of migration within the respective altitude range (50 m vertical resolution). Donut charts aggregate this further to coarser 200-m classes and display the proportion of migration occurring above 1000 m (patterned). Red highlights indicate the altitude range of onshore energy infrastructure in the Netherlands, which is generally present in the lowest 200 m of the atmosphere. Donut chart proportions do not sum to 100% due to rounding. The small inset map of the Netherlands shows the locations of both radars (solid dots) and the surrounding areas up to 35 km (circles) from which altitude distributions are aggregated.
Fig. 3. a, c Observed combinations of migration passage and mean wind power density, a measure of wind power potential, in North-Holland. Red circles represent average values for candidate sites and their size reflects the relative candidate site area. The grid reflects binned values of migration and wind power density, with color shading indicating the type of combination: orange = high migration passage, blue = high wind power density, dark browns and blues = both high. White lines indicate averages for wind power density and seasonal migration passage. b Spatial distribution of autumn migration (orange hues) and wind energy (blue hues) in North-Holland. Candidate wind energy sites are shown in bright red. The highest and lowest autumn migration passage sites are linked to their positions in a and c, emphasizing large differences between sites in autumn, but not in spring. Shaded areas mark grid cells for which over 25% of the input data, prior to filtering, were impacted by ground clutter. Migration passage in these regions may be compromised in either direction: overestimated due to remaining clutter artifacts or underestimated where terrain features partially obstruct the radar’s lower scanning angles.
To reduce negative impacts of #renewables (eg #windenergy) on migrating birds, we need to know *where* and how *high* they fly. Using weather radar, we mapped 6yrs of nocturnal migration over the Netherlands, revealing patterns we can use to avoid and minimize impacts:

(1/8) Stel je voor dat een Chinese #fabriek een hek om de #Veluwezoom zet, bewapende #rangers inhuurt en de mensen die in de buurt wonen de natuur niet meer inlaat. Dit alles omdat de bomen #uitstoot in China moeten compenseren.
Heel veel beterschap Anthonie!
⛰️ A groundbreaking German study proved that pesticides spread much further from the field than previously believed. They detected #pesticides at every location, 63 in total.

Fijne column van #Jellereumer vandaag in #Trouw. Met een fantastische droom aan het eind!
De fel-oranjerode vuurvlinder is eigenlijk een blauwtje, en hij is nogal kieskeurig

Rups van de helmkruidvlinder, een nachtvlinder als hij/zij zich verpopt tot volwassen exemplaar. Vandaag in de Goudse Heemtuin
Deze prachtige vlinders vliegen nu volop, Haaksbergerveen 21 APR 25
POSTDOC VACANCY: We have a 3 year position available studying variation in population size and habitat use of red knots in the #WaddenSea. We the aim to understand bottom-up and top-down processies. More info here: workingat.nioz.nl/o/postdoc-po... #WATLAS #SIBES #ornithology #movementecology
Actually a charming approach to reducing insect mortality by staggered mowing. But still: Nothing mows better (in terms of biodiversity) than a cow or a horse at low stocking density. And I haven't ever seen a machine producing dung! 😎

Borstelbekboorvlieg (Chetostoma curvinerve). Een zeldzame boorvlieg die recent NL begint te veroveren.

Now this is exciting.
Antonin and his team have just published a study showing that the number of migrating hoverflies through Czechia are positively correlated with the numbers of birds!
Suggests that the birds are using the flies as fuel on migration.
