The long march of the human genes

Dr. Andrea Manica




Where do we, modern humans, come from? Most likely we originated in Africa, specifically East Africa, and successively colonized all other continents (e.g. see here). This is called the Out-of-Africa theory for the origin and early spread of anatomically modern humans (see here). Whilst there is quite good consensus on the origin in East Africa, considerable debate has surrounded the timing and pattern of spread of modern humans out of Africa. 

Our seminar speaker of this week, Dr. Andrea Manica from the Department of Zoology at Cambridge University and head of the Evolutionary Ecology Group, will present us his work of the last few years about this topic. Andrea and his group are broadly interested in the causes and consequences of animal movements and the topics addressed range from understanding and predicting individual strategies, to using population genetics models to reconstruct and understand the timing of past dispersal events, to the role of species interactions in the spaital ecology of populations.


Abstract
Anatomically Modern Humans first appeared in Africa approximately 200 thousand years ago (kya), but failed to colonise other continents until much later (approximately 60-70 kya). What caused such a delay, and what are the consequences of their subsequent fast expansion once they abandoned their ancestral home? Using spatially-explicit genetic models informed by paleo-climate reconstructions, I will explore the role of climate change during the Pleistocene in driving the time and tempo of the range expansion of Anatomically Modern Humans.

Strategies for the Control of the invasive American mink (Neovison vison) in a Natural Park

Prof. Paloma Moran



As already recognized by Charles Elton (see here), invasions by non native species are a major threat to species survival. Not only can non native species displace native ones, but often this can lead also to major ecosystem changes. Often invasions by non native species are caused directly or indirectly by human activities and can lead to considerable economic costs. To manage these problems and to save native species, not rarely it is necessary to control or eradicate the invasive species - often a rather difficult task.

Our seminar speaker of this week, Prof. Paloma Moran form the University of Vigo in Spain, is a conservation geneticists who works also on the management of invasive species and will present us a project she is currently involved in, focussed on controlling feral mink populations in a natural park.


Abstract:

The American mink a semi-aquatic carnivore, originating from North America, which was imported into Europe for fur farming at the beginning of the 20th century. Due to massive escapes, farm damages, deliberate releases and/or accidents, feral mink populations are now established in many ecosystems. I discuss in this talk actions taken in the Natural park of the Atlantic Islands (Spain) to eradicate this species, including trapping and genetic monitoring.
