New publication on methodological developments in landscape genetics

On March 01 2019 by Simon Dellicour
Our article titled “Landscape genetic analyses of Cervus elaphus and Sus scrofa: comparative study and analytical developments” has recently been published in Heredity. In this study, we describe and use a landscape genetic workflow to compare spatial patterns of genetic variability and the impact of environmental factors on genetic differentiation. Red deer and wild boar are two major game species whose populations are managed and live in areas impacted by human activities. Read more...

New publication on the global distribution of livestock

On October 28 2018 by Marius Gilbert
In collaboration with the Food and Agriculture Organization of the UN (FAO) and other collaborators, we are publishing this week in Nature Scientific Data the result of several years of research to improve global data on the distribution of livestock (cattle, buffaloes, horses, sheep, goats, pigs, chickens and ducks). These new data sets provide estimates of the density (individuals / km2) of these species at a spatial resolution of 5 minutes of arc (approximately 10 km at the equator) over the globe.

2-year post-doc position in global livestock distribution modelling

On September 05 2018 by Marius Gilbert
A 2-year post-doc position starting immediately is available to work on global spatial and temporal distribution models of livestock. Description The global livestock sector faces major challenges in terms of the sustainability of its development due to the considerable externalities that livestock production has on society, health and the environment. High-resolution maps of livestock are essential tools to assess the sustainability of livestock production systems. Maps allow, for example, the estimation of potential impacts of various hazards that have strong spatial dimensions such as the release of pollutants. Read more...

New 2-years post-doc position announcement in disease spread modelling

On February 12 2018 by Marius Gilbert
A 2-year post-doc position is opened to work on spatial epidemics and phylogeographic models applied to Bluetongue. Description Several factors can contribute to the spread of animal diseases their relative effect can be difficult to disentangle. In this project, we aim to compare spatial epidemic models and spatial phylogeographic models in their capacity to quantify the effect of different factors on patterns of spread, using past bluetongue epidemics as study system.

Recent papers discuss the interplay between agricultural intensification and avian influenza in Asia

On January 08 2018 by Marius Gilbert
Two papers were recently published on this topic from different perspectives. In the paper Intensifying poultry production systems and the emergence of avian influenza in China: a ‘One Health/Ecohealth’ epitome, we discussed different sets of ecological and epidemiological pressures that could have lead to the emergence of avian influenza in Asia. In the paper Could Changes in the Agricultural Landscape of Northeastern China Have Influenced the Long-Distance Transmission of Highly Pathogenic Avian Influenza H5Nx Viruses? Read more...

A new paper in Science on antimicrobial consumption in food animals

On September 29 2017 by Marius Gilbert
In this paper, published in Science today, we conducted a first global assessment of different intervention policies that could help limit the projected increase of antimicrobial use in food production. The paper is lead by Thomas Van Boeckel a former member of the lab, now at ETH Zurich, and was carried out in collaboration with researchers from FAO, Princeton university and CDDEP. The paper reports that worldwide antimicrobial consumption is expected to rise by a staggering 52% and reach 200,000 tonnes in 2030 barring any actions. Read more...

Spatial Statistics 2017 conference in Lancaster (UK)

On July 01 2017 by Marius Gilbert
Three members of the lab attended the Spatial Statistics 2017 conference in July, with talks on the larges-scale tranbsferability of H5Nx models (J. Artois), on farm distribution models (C. Chaiban) and on the latest developments of the gridded livestock of the world database (M. Gilbert).

H5N1 model helps predicting the spread of H5N8

On February 02 2017 by Marius Gilbert, Jean Artois, Madhur Dhingra & Catherine Linard
(Updated 2nd Feb. 2017) We evaluated the predictive capacity of our global H5N1 suitability model published a few month ago in e-life, and based on HPAI H5N1 and H5Nx records of years 2006-2015 in its capacity to predict the current wave of HPAI H5N8 across Europe. On February 1st, we extracted all the winter 2016:2017 H5N8 HPAI cases in domestic poultry (i.e. excluding wild bird cases) from the Empres-I database. In the figure below, the cases are distributed over the HPAI H5N1 model (left) and HPAI H5Nx clade 2. Read more...

New papers in e-Life on H5N1

On December 22 2016 by Marius Gilbert
A new paper has just been published in e-life mapping the global distribution of areas where HPAI H5N1 would have a high chance of sustained transmission upon introduction, as illustrated in the figure below. This was our first experience with e-life and we really enjoyed the quality and transparency of the peer-reviewing process, where referee comments are summarized and consolidated by the editorial team, and published, with their responses alonside the paper.

New paper on wild birds and the spread of avian influenza

On October 20 2016 by Marius Gilbert

A new H5N8 virus emerged in the years 2014-2015 and rapidly spread across several continents, causing several avian influenza outbreaks in Europe and in the USA. As part of a large consortium of researchers, we published this week a new paper in Science that combines phylogeography, epidemiology and data on poultry trade to conclude that wild migratory birds played an important role in this rapid spread.
