Evolution, adaptation et gouvernance des écosystèmes continentaux et côtiers 

Séminaires BioGeCo sur la phénologie

le 08 septembre 2014 de 10h à 12h

Si vous avez manqué le séminaire de Lisa Wingate sur le suivi de la phénologie des plantes par proxi-télédetection qu'elle a donné à BioGECO au printemps dernier, venez écouter un ou plusieurs séminaires tournant autour du suivi de la phénologie par proxi- ou télé- détection dans le cadre de la visite de chercheurs étrangers (italiens et américains). Pour en savoir plus et connaître le programme de la matinée, cliquez sur "lire la suite".

Presentation by Edoardo Cremonese, ARPA, Torgnon, Italy 10:00 - 10:30
Title: Phenology and climate change in the Alps
Talk Summary: Edoardo will present the findings and spirit of the phenology network established between Italy and France during the EU project PhenoALP (PhenoALP is a EU co-funded Interreg Project, under the operational programme for cross-border cooperation Italy–France (ALCOTRA) 2007-2013 aiming at getting a better understanding of phenological changes as related to climate change in the Alps. Project lasted between 2009 and 2012) and strengthened within the new project ePHENO (ePHENO represents the continuation of PhenoALP and aims at enlarging and strengthening the phenology monitoring network, by including new subjects and promoting an increased participation in dissemination and awareness on phenology. The project started in January 2012 and will last until 2015). More details of the research can be found at the website: 
Presentation by Lisa Wingate, INRA ISPA, Bordeaux, France 10:30 - 10:50
Title: Opportunities to investigate the functional phenology of ecosystems using a European digital camera network 
Talk Summary: Phenology is deemed a robust integrator of the effects of climate change on natural systems and it is now recognised that improved monitoring of phenology on local-to-continental scales is now needed. At FLUXNET sites around the world overlooking forests, pastures, and croplands, we have identified an opportunity to establish precision measurements of phenological events by simply mounting networked digital cameras (‘webcams’) and recording daily (or even hourly) images of the vegetation canopy. Within Europe this network is in its infancy, however it is growing steadily with almost 40 sites identified across different ecosystems. In this talk I will present the efforts of this growing, European phenocam network and illustrate with examples taken from the network some of the key advances in linking camera measurements to canopy biochemistry and function. More details about Lisa's research can be found here: https://www.researchgate.net/profile/Lisa_Wingate
Coffee break (20 minutes)
Presentation by Tim Brown, Australian National University, Canberra, Australia 11:10 - 11:40
Title: Phenocams, Phenomics and TraitCapture: New technologies for enabling NextGen Ecosystem monitoring
Talk Summary: Understanding global environmental change is a grand challenge of the 21st century. Satellite remote sensing informs our understanding of broad ecosystem processes but quantifying multi-scale ecological processes at high spatial resolution is still extremely difficult. Digital timelapse cameras (phenocams) and other new near-surface remote sensing tools like UAVs and mesh sensor networks can bridge the data gap between satellite and field-level observations. Coupling phenological data with microclimate measurements and full genome sequencing allows us, for the first time, to understand how phenotypes emerge as a the interaction between genotype and environment. This precision "trait dissection" allows us to explore local genetic adaptation and phenotypic plasticity to better predict climate change impacts for plant populations. Effective NextGen ecosystem monitoring requires rigorous use of data standards and development of novel data analysis and software pipelines for effectively managing and visualizing of terabytes of complex ecological and genetic information.
Bio: Tim brown is a senior postdoctoral fellow at Australian National University in Canberra Australia. Tim received a PhD from the University of Utah in the US in 2006 for his work modeling self-organized swarming behavior in New World army ants. In 2006 he left academia to found the company TimeScience to create camera and software systems to enable long term ecosystem monitoring. In 2012 he moved to the ANU in Australia as a postdoc at the Borevitz lab developing software and hardware pipelines for phenomics research in lab and field applications.

Presentation by Mirco Migliavacci, Max Planck Institute, Jena, Germany 11:40 - 12:10
Title: tba
Talk Summary: Mirco will present his research at larger scales using remote sensing products. More details about Mirco's research can be found on his website: https://www.bgc-jena.mpg.de/bgi/index.php/People/MircoMigliavacca
Lunch and Discussions will follow between 12:15 - 13:15
