As part of the French-American Science Festival 2016 in Chicago, Pr. Régis Céréghino (Paul Sabatier University in Toulouse) will give a free public lecture n the impact of human activities on freshwater biodiversity.
About the presentation
Decades of over-harvesting, habitat destruction, ecosystem contamination and changes on atmospheric gases have led to a global biodiversity crisis, and freshwater biodiversity has declined as a whole faster than either terrestrial or marine biodiversity over the past 30 years. In addition to their intrinsic value, species are responsible for the capture, conversion and flow of energy and nutrients through ecosystems – these functions ensure processes upon which humans ultimately depend.
In this talk, the consequences of the most frequent stress agents from human origin on fish and invertebrate communities of wetlands, rivers and lakes will be outlined. Climate warming, hydrological alterations, and changes in land use are major drivers of local extinctions and invasion by non-native species, affecting species dominance and interaction patterns. Then, you will learn how field surveys and manipulative experiments help to unravel the mechanisms underlying these effects, and yield theoretical frameworks that support environmental management action plans.
Free public lecture, in English, followed by Q&A with the audience and a wine and cheese reception. Exclusive occasion to attend a lecture with such talented French scientists!
About the speaker
Régis Céréghino, 47, earned his Ph.D. degree in freshwater biology in 1997 at Univ. Paul Sabatier, Toulouse, where he was first appointed in 1999 and is Full Professor since 2005. He’s been Head of several research groups focused on freshwater biodiversity since the early 2000s, and is currently Deputy Head of the Department of Functional Ecology and Environment.
He is interested in the role of species diversity and interactions, notably within food webs, in determining ecosystem responses to environmental variability and anthropogenic perturbations. He mostly uses aquatic insects as model organisms, in a wide range of temperate and neotropical habitat types such as plant-held waters, ponds, or rivers. He has authored/co-authored 130 articles in international scientific journals, book chapters, and popular science magazines, and serves in the editorial teams of several international journals of ecological and freshwater science.
About the French-American Science Festival
Following the great success of the fourth edition in 2015, the Office for Science and Technology in Chicago is organizing the fifth edition of the French-American Science Festival from April 25 to April 28th, as part of the French Innovation Week organized by the Consulate General of France, the French-American Chamber of Commerce in Chicago and the Alliance Française of Chicago.
Since 2011, the French-American Science Festival brings together scientists and educators from universities, national laboratories, industries and non-governmental organizations from France and the U.S, representing a wide range of fields, from biology to nanotechnologies, through astronomy. Every year, two general public conferences with leading scientists are organized on highly topical issues, in partnership with the Alliance française. The other conference will be held on April 28th and will be focused on the mechanisms of ageing. In addition, in partnership with Northwestern University, and particularly with the Rick Morimoto’s laboratory, a full day of science education and outreach allows children from the schools of the Chicago area to discover science and to learn the scientific approach.
