Open Letter from Dr. Christopher Portier on His Review of the Carcinogenicity of Glyphosate European Union Authorities

31 Mai 2017,

Publié par Bioécologie

Executive Summary: The European Food Safety Agency IEFSA) and the European Chemical Agency IEChA) have completed their assessments of the carcinogenic potential of glyphosate and concluded that the evidence does not support a classification for glyphosate. The raw data for the animal cancer studies for glyphosate have been released, and a reanalysis of these data show eight instances where significant increases in tumor response following glyphosate exposure were not included in the assessment by either EFSA or EChA. This suggests that the evaluations applied to the glyphosate data are scientifically flawed, and any decisions derived from these evaluations will fail to protect public health. I ask that the evaluations by both EFSA and EChA be repeated for all toxicological endpoints and the data underlying these evaluations be publicly released.

PhD position: Genomics basis of the arms race between a parasite and its host, the threespine stickleback

17 Mai 2017,

Publié par Bioécologie

A fully-funded 4-year PhD position is available in the Aubin-Horth and Landry Laboratories at Universite Laval in Quebec City, Canada. The PhD student will work on a project aimed at dissecting the genomic bases of the co-evolution between the threespine stickleback and its worm parasite, Schistocephalus solidus.

The candidate is expected to have a Master degree in biology or a related discipline, and a background in bioinformatics (R, Python or Perl), statistics and genomics. The candidate should have strong leadership skills, motivation and creativity and be able to work in a team of collaborators.

The Aubin-Horth and Landry Laboratories are located at the Institut de Biologie Intégrative et des Systèmes (IBIS) at Université Laval. IBIS offers a very stimulating training environment and cutting edge on-site platforms in genomics, proteomics and microscopy. The Aubin-Horth Lab members are evolutionary biologists, neuroendocrinologists and behaviour biologists working together using an integrative approach to uncover the mechanisms underlying the alteration of stickleback behaviour by its endoparasite, by studying both the host and its parasite at the molecular, cellular and hormonal level, as well as how they interact. The Landry lab is an international team of 15 students, PDFs and research associates from different backgrounds (microbiology, biology, bioinformatics, biochemistry) addressing questions in evolutionary cell and systems biology.

The application package (1 single PDF file) should include a motivation letter demonstrating the interest of the candidate for the field and his/her ability to perform this type of research, a CV and the contact information of three people who can provide letters of reference. The file should be sent to Nadia.Aubin-Horth@bio.ulaval.ca

Starting date could be as early as September 2017. The competition will remain open until a candidate is selected.

AnaEE-France (Analyses et Expérimentations sur les Ecosystèmes - France)

6 Mai 2017,

Publié par Bioécologie

AnaEE-France est une infrastructure nationale de recherche dédiée à l’étude des écosystèmes continentaux et de leur biodiversité.

Elle met à la disposition de la communauté scientifique internationale 22 services composés de plateformes expérimentales (en milieu contrôlé, semi-naturel ou naturel), de plateformes d’analyses et d’instrumentation partagée.

AnaEE France permet aussi un accès aux données et à des plateformes de modélisation.


Les activités humaines ont considérablement altéré les milieux naturels à travers le monde et soulèvent des questions sociétales vitales telles que la fourniture pérenne de ressources biologiques et de services écologiques. Dans ce contexte, un défi scientifique majeur consiste à comprendre et prédire la dynamique de la biodiversité et des écosystèmes. Pour cela, nous avons besoin d’une véritable biologie intégrée combinant les sciences du vivant et environnementales. L’infrastructure AnaEE France « Analyse et Expérimentation sur les Ecosystèmes - France » répond à cet enjeu. Elle est coordonnée par le CNRS, l’INRA et l’Université Joseph Fourier, et constitue la contribution française au projet européen AnaEE inscrit sur la feuille de route du Forum européen sur les infrastructures de recherche (ESFRI).
