Mammals, biogeochemical cycles, & climate

Mammals influence primary productivity, and the functioning of ecosystems by consuming biomass, predating on mammals and other animals, and recycling nutrients. These interactions have consequences on carbon dynamics,biogeochemical cycles, green house gas fluxes, and ultimately climate. During my EU H2020 Marie Skłodowska-Curie project "MegaBiCycle", I have explored the global role of large terrestrial herbivores in nutrient cycling and climate and produced a financial valuation of wild animal carbon services. I am now expanding to marine mammals and carnivores.
REMAP - Global model of mammals populations

REMAP (REproducing MAmmal Populations) is a global model simulating the population dynamics of different mammal functional types competing for resources. Currently REMAP simulates present-day and Late Pleistocene herbivore populations and includes up to 28 Herbivore Functional Types defined by their diet, digestive system, and body mass. REMAP can be coupled with global vegetation models to study the ecology and functional role of mammals in ecosystems and biogeochemical cycles; a description of REMAP can be found in our publication.
PNuts: Global database of plant nutritional properties

Plant nutritional properties (crude proteins, fibers, minerals, tannins, and dry matter) and energy content are key traits determining the quality and quantity of food intake of humans, wild and domestic animals. I am interested in how these properties vary as a function of other plan traits and how they influence animal and human eco-physiology and food quality. To investigate these questions, we have created PNuts a global database of Plant Nutritional values, containing 12000+ georeferenced records and 1000+ species of nutritional traits for different plant organs (leaf, stem, fruit, seed, flower, bark, etc.). PNuts can be used for macroecology, modelling, and plant ecology studies. Please get in touch if you would like to get involved to improve PNuts or develop a collaboration.

News and press coverage

July 2022: Our article Value wild animals’ carbon services to fill the biodiversity financing gap was featured on the cover of Nature Climate Change. We describe a new framework to value the carbon services of wild animals to achieve the win-win of mitigating climate change, reducing biodiversity loss, and financing local communities to be nature caretakers.
June 2022: Our article on Financing conservation by valuing carbon services produced by wild animals was published in PNAS. We estimate that if African forest elephants were protected, their carbon services would be worth $20.8 billion within the next 10 years, that is enough to finance conservation and improve socio-economic conditions of local communities.
April 2022: BBC Future published an article on the importance of forest elephants and African rainforests in mitigating climate change and the valuation of carbon services provided by elephants that could help finance conservation.
September 2020: Through a collaboration with financial economists, including the International Monetary Fund, we evaluated the carbon service provided by forest elephants. "Each elephant provides a service worth up to 1.75 million USD!. The IMF also produced a podcast featuring myself and IMF assistant director Ralph Chami . We are now developing a pilot conservation project in central Africa so that elephant services can be used to finance their protection and conservation and for the benefit of local communities.
December 2019: Our opinion paper on how to include trait variability in vegetation models was published in Trends in Ecology and Evolution "Towards a New Generation of Trait-Flexible Vegetation Models" . Thanks to all the colleagues from PROFOUND who participated in this work!
August 2019 and press coverage: Nature Geoscience published our paper on the effect of forest elephants on the carbon cycling of African tropical forests . The paper received worldwide press coverage including The New York Times , The Conversation , The Independent , and several news outlets in countries such as India, Russia, Italy, New Zealand, Spain, and was even featured in The Poetry of Science .

May 2019: I was awarded the Marie Skłodowska-Curie Individual Fellowship which will allow me to spend two years at the Laboratory of Climate and Environmental Sciences (LSCE) in France working on my "MegaBiCycle" project on the role of megafauna on biogeochemical cycles and climate! My supervisor will be Philippe Ciais

Press coverage: The Independent and Atlas Obscura covered our recent publication regarding the conservation of birds in East Africa.

September 2018: Article and blog post. Our article on bird conservation in the Albertine rift was published in The Condor, and I was invited by the American Ornithological Society to write a piece for their blog, cowrote with John Bates.

April 2018: Seed masting working group at the University of Milan. The TG-20 had its final meeting to set the ground for future collaborations on masting research to follow up on our article on how to model masting.

March 2018: I joined the Laboratory of Climate and Environmental Sciences (LSCE) in Paris, France for a postdoc position. I was awarded a CEA-Eurotalents fellowship part of the Marie Sklodowska-Curie Actions Programme. At LSCE I will work with Philippe Ciais to study the role of large herbivores in biogeochemical cycles.

Short Bio

I hold a PhD in Ecology, main topic "modelling plant-animal interactions in tropical forests". Before becoming interested in Ecology, I completed a Master's degree in Computer Science and, among others things, worked on educational and commercial videogames. Thanks to my diverse background and mix of skills I have worked across ecosystems and taxa, from African elephants to Greenland fishes, and had the opportunity to experience life and cultures in countries around the world. I also enjoy teaching and science outreach activities.
