Yesterday, started at Université Paul Sabatier (Toulouse, France) the second meeting of the INFRAGECO-BiodivERsA project. During the next days, researchers from Instituto Gulbenkian de Ciência – IGC, Institute of Zoology from the University of Veterinary Medicine (Hannover, Germany), Laboratoire Evolution et Diversité Biologique from Université Paul Sabatier (Toulouse, France), and the Institut de Mathématiques from … More 2nd Meeting in Toulouse, France
It is now online our new article on the genetic diversity and demographic history of the mouse lemur Microcebus tavaratra. In this work we have assessed the level of genetic diversity of this threatened lemur and compared it with other species of the same genus. In addition, we have quantified its level of genetic structure … More New paper about mouse lemur is out!
Team Radespiel has returned from 6 months in Madagascar as of November 2017. Overall, the first season of the project was very successful and we are all very happy with the results. We captured or sampled many species during our time in Ambanjabe, Ankarafantsika National Park including sifaka, sportive lemurs, and mouse lemurs as well … More “Team Radespiel” Back From the Field
The IICR (inverse instantaneous coalescence rate) is time- and sample-dependent parameter that was originally introduced by Olivier Mazet in an article published in 2016 in Heredity. Imagine that you have two haploid genomes, one question a population geneticist would ask is “what could I say with so much genomic data about the demographic history of … More Distinguishing structure from panmixia: Simona Grusea submitted our latest article to Theoretical Population Biology
Gabriele Sgarlata, still in Madagascar, has just submitted the last version of his manuscript on the genetic diversity and demographic history of the mouse lemur Microcebus tavaratra. We are waiting for the final and official acceptance letter, but based on the latest comments of the editor of the International Journal of Primatology, the paper should … More Gabriele Sgarlata submitted the latest version of his manuscript on Microcebus tavaratra
In the last couple of weeks Lounes Chikhi has been in Madagascar, mainly in Antananarivo, the capital, and in Mahajanga, in the NW of Madagascar. He met with Barbara Le Pors who is responsible for the field work and for all the students. He also met with our Malagasy colleagues who have made that project … More Lounes Chikhi is in Madagascar
Guillaume Besnard, head of the Toulouse INFRAGECO team, in the Evolution & Diversité Biologique (EDB) lab, opened a position for a post-doctoral researcher to work on the population genomics of Madagascar olive trees (genus Noronhia). The position was advertised at the beginning of the summer and we were lucky enough to have several very good … More New member to join Guillaume Besnard’s team in Toulouse!
At the IGC we have been using our internally developed program to simulate complex demographic scenarios, SINS (Simulating INdividuals in Space), to simulate scenarios of habitat loss and fragmentation and to study how these events may affect the genetic patterns of populations. SINS helps us comparing different explanations for the data that we observe in the … More SINS is around the corner
Yesterday, we sent the corrected proofs of our first INFRAGECO manuscript to Heredity. In this manuscript we extend the original work of Mazet et al (2016) on the IICR (inverse instantaneous coalescence rate). In a few words, we study the properties of the IICR under various models of population structure. We thus try to understand … More Proofs of the first article of the INFRAGECO project sent yesterday to the journal Heredity (nature publishing group) !
Guillaume Besnard, PI of the EDB team just came back from a mission in Madagascar. There he joined the team led by Barbara Le Pors and with the help of Emmanuel Rasolondraibe, Tantely Ralantoharijaona, Jacquis Randriamaroson, and local guides hired in the different localities, they collected samples from various species, including Noronhia (Madagascar olive tree), … More Guillaume Besnard is back from field work in Madagascar
