#PostDoc Alert! PhD in #Biology or #EnvironmentalSciences? Strong background in #ForestEcology, DNA-based biodiversity assessments, #Bioinformatics, and experimental planning? Our #ForestEntomology Group offers a 2-year #PostDoc position 🌳🧬💻: apply.refline.ch/273855/1798/... #ScienceJobs #eDNA
Job offer: PostDoc in “Biodiversity and ecosystem functioning in European forests in the face of global changes” 80-100% (f/m/d) The aim of the projects is to investigate the impact of global changes on temperate forests toward designing management plans that allows ecosystem resilience and high levels of biodiversity. Within these projects, you will develop standard and more efficient ecological monitoring methodologies to understand how different aspects of biodiversity and/or associated ecosystem processes, in particular deadwood decomposition, in forests are altered by global change factors such as climate change, disturbances, and management-induced structural changes at different spatial and temporal scales. Through this research, you will gain a better mechanistic understanding of these relationships as a basis for predicting future changes related to management decisions and climate change. To measure biodiversity, you will use cutting-edge DNA-based methods, such as e-DNA metabarcoding of fungi, from soil and dead wood, and detecting arthropods and mammals from vegetation surfaces. Data on biodiversity and forest functions will be analyzed in an interdisciplinary manner. Depending on your skills and expertise, you can focus on more technical aspects of biodiversity quantification using eDNA, fundamental ecological research questions on modelling ecosystem processes or the more applied design of management practices. You are expected to publish your findings in high-impact journals and present them at international conferences. You hold a PhD degree in Biology or Environmental Sciences or in a related field and have a strong background forest ecology, in DNA-based biodiversity assessments (e-DNA metabarcoding), bioinformatics and multivariate statistical analyses, and/or experimental planning. Furthermore, we expect very good knowledge in R programming, a good command of English, as well as strong skills in scientific paper writing.

Nématode: ce ver microscopique ravageur menace les forêts de pins de cette région de France
Le nématode, un ver microscopique, a été détecté pour la première fois en France à Seignosse dans les Landes. Un ver ravageur venu d'Amérique du Nord et qui est très dangereux pour les pins.

A daily reminder that #RussiaIsATerroristState
halushka.bsky.social Olena Halushka @halushka.bsky.social · 1d
The death toll in the russian terrorist strike against Ternopil has risen to 35. The 12yo girl succumbed to her wounds after doctors had hard fought to save her life for 9d. Her mother was killed too and her sister is still in the hospital.

35 innocent souls stolen at once.
35.

The war will end when Russia stops fighting. Therefore, pressure has to be put on Russia, so that they stop believing that they will win. Why is that so hard to understand?

Russia killed 33 people, including six children, by a missile strike on Ternopil on November 19.

94 more people were injured, 18 of them children. Six people remain missing.

Ukrainian rescuers worked for four days at two locations, managing to save 46 people, including seven children.

Le nématode du pin Bursaphelenchus xylophilus est un ver microscopique capable de tuer certains conifères en bloquant la circulation de leur sève.

Il a récemment été détecté en France pour la 1e fois, dans les Landes. Des mesures de restriction sont mises en place pour empêcher sa propagation.

The only real peace plan is kicking russia the hell out of Ukraine & bringing criminals to account.

Everything else is just a postponed war — a debate on modalities about when and how russia gets to rearm and strike again.

History lessons teach the world leaders nothing.

This is not a peace plan. It is a proposal that weakens Ukraine and divides America from Europe, preparing the way for a larger war in the future. In the meantime, it benefits unnamed Russian and American investors, at the expense of everyone else.

Oleksandra has years of experience documenting war crimes in de-occupied Ukrainian territories. She is a strong human rights advocate and consistently emphasizes that occupation is simply another form of war, it never brings peace or freedom to the local population.
