Yesterday, between storms Austen and Boelo, at the Atlantic. The spray got high above the 30m cliffs. Now we sit comfortably in a warm and cosy house with scones, coffe, and a nice book and watch the wind waves on the lake getting higher during Boelo.
A dark and wet limestoneplateau glittering in the sun. Some more cliffs and glittering sea in the background and enourmous sea spray to the right of the cliff. Sunny sky with some fluffy clouds.

Black, almost V-shaped slopes covered with spruce (tops visible) to the left and deciduous trees to the right. Down the valley are several mountains visdible behind each other, the frontmost dark grey, then gradually lighter towards blue/grey pastel. The sky right above the mountain tops is dark bright orange with less intensity further up, to the top very light pastel blue. The colour gradient is less transient but has almost sharp boundaries.

Interested in pursuing your PhD in Alpine Ecology? How do ecosystems emerge after glacial retreat? Come with us @ufz.de as a PhD researcher on the development of vegetation and microbiome in glacier forelands. recruitingapp-5128.de.umantis.com/Vacancies/33... #ecojobs #ecology #Alps #AlpineEcology
The job
Cooperating in the field of periglacial vegetation development with other Helmholtz centres, we offer a PhD position (f/m/x) to survey and analyse the development of vegetation and associated microbiomes in glacier forelands of the Alps.

Your tasks
• Collection of vegetation data in glacier forelands and surroundings
• Collection of soil and root samples
• Analyses of soil and root associated microbiomes through meta-barcoding
• Analysis of the link between vegetation and microbiome development as a function of (successional) time
• Scientific publications

We offer
A lot of things, but space does not permit. Please see the link for details.

Your profile
• Degree (Master, Diploma) in biology, ecology, geoecology or comparable courses of study
• Experience in the field of vegetation methods (vegetation surveys)
• Field work experience in soil and root sampling for microbiome analysis
• Lab skills to analyse the microbiome like DNA extraction, PCR, and sequencing
• Knowledge of the Northern Alpine flora
• Experience in high mountains and the ability to hike several hours a day and 1000 metres in altitude with luggage and equipment
• Orientation skills in the mountains
• Ability to work independently and solve unexpected problems
• Statistical skills (preferably in R), knowledge of data storage (databases) desirable
• Very good knowledge of English (communication in the working group, reading technical literature, writing technical articles)
