3rd IMBALANCE-P annual meeting – Paris, 1st – 3th February 2017

IMBALANCE_P_Logo_Color_kick off abstractsThe ERC Synergy Imbalance-P project has been running for two years already. A lot of work has been done and some other still needs to be carried out. It is, therefore, time for us to meet again in a confortable city such as Paris.

The format will be similar to last time, researchers will present some of their work/results/projects within the Imbalance-P in short talks of about 15 minutes allowing participants to ask some questions. It is also planned to have time to allow researchers to discuss within the different working groups (experimental, synthesis, modelling…) and among them.

The main aims of the Paris meeting are to:

  1. Present and discuss past, present and future work within the Imbalance-P project.
  2. Share and discuss the results obtained by the different groups.
  3. Develop synergies amongst groups and researchers by increasing collaboration through sharing thoughts, ideas, objectives, experiments, observations and data.
  4. Create a venue where co-authors of different manuscripts can get together to forward their writing and possibilities for such activities to be initiated.

IUFRO 2017 Congress – Biodiversity, Ecosystem Services and Biological Invasions

For the 125th anniversary congress of IUFRO (Freiburg, September 2017), Stephan Pietsch (IIASSA) has organised, together with Plinio Sist (IRAD) and Robert Nasi (CIFOR), as session entitled: “Progress in tropical forest management: Assuring sustainability, avoiding degradation and assisting restoration”.

Here we attach the full description of sessions under theme 4. The call will be opened until the end of november.

IUFRO 2017 – Session 4

Imbalance-P participates in the 53rd ATBC 2016 Meeting

Dr. Oriol Grau (CREAF) participated with a talk about his work on tropical forests in the 53rd meeting of the Association for Tropical Biology and Conservation (19-23 June 2016 – Montpellier, France).

The speach, entitled “Do soil characteristics determine forest structure and dynamics in poor Amazonian soils?” took place under the session “Management impacts on biodiversity and carbon/nutrient balances in the tropic” moderated by Prof. Stephan Pietch (IIASA).

Grau, O., Peñuelas, P., Ferry, B., Freycon, V., Lilian, B., Desprez, M., Baraloto, C., Chave, J., Descroix, L., Dourdain, A., Guitet, S., Janssens, I., Sardans, J., Herault, B. Do soil characteristics determine forest structure and dynamics in poor Amazonian soils? 53rd ATBC 2016, 19-23 June, Montellier, France.


Josep Peñuelas has been awarded Ramón Margalef’s Prize in Ecology 2016!

Ramon Margalef’s Prize in Ecology was created in 2004 by the Catalan Government to recognize people, all over the world, who have distinguished exceptionally in the field of ecological science. The award honors the memory of Professor Ramon Margalef (Barcelona, 1919-2004), who made a decisive contribution to establishing modern ecological science, to the point where he is regarded as one of the world’s leading figures in the field.

The Catalan television interviewed him yesterday. You can see the video here: Els Matins de TV3

Workshop – Nutrient limitation on land: how accurate are our global land models?

Philippe Ciais, Josep Peñuelas, Sara Vicca and Daniel Goll in collaboration with Chinese colleagues, organised a workshop entitled: Nutrient limitation on land: how accurate are our global land models?

The workshop was hosted by the Northwest Agricultural and Forestry University from the 15th to 17th June 2016 in the Yangling, Shaanxi, China.

ERC Imbalance-P participates in the international workshop: “Phosphorus Cycling in Terrestrial Ecosystems”, May 23-25, 2016 Townsend

Phosphorus Cycling in Terrestrial Ecosystems: Taking a new approach to advancing our fundamental understanding through a model-data connection

Townsend, Tennessee, USA (May 22-25, 2016)

Aim of the Workshop:

Phosphorus (P) has been shown to limit a number of fundamental processes in a wide range of ecosystems; however, despite its importance, most earth system models do not currently include any manner of the P cycle. This hinders the utility of these models for generating and testing hypotheses and for forecasting the effects of global change. Importantly, a critical challenge for P modeling efforts is also a critical challenge for the scientific community as a whole; namely, determining a way forward for improving our understanding of the key drivers, processes, and global change responses of the P cycle. Bringing together P experts would allow for the addressing of this need through: (1) a more synthetic understanding and conceptualization of P cycle dynamics, (2) the merging of varied P and associated data, (3) improved process-based modeling of the P cycle, and (4) P data-model integration. Another potential success stems from the power of explicit collaborations between empiricists who study P cycling and modelers considering the inclusion of P into models.

Imbalance-P participation:

During the forth session of the workshop, entitled: “Understanding P processes in the context of global change”, Prof. Josep Peñuelas, Prof. Ivan Janssens and Dr. Daniel Goll  presented the some of the results of the ERC Imbalance-P project in the field of experimentation, data analysis and modelling.

ERC Imbalance-P organises a bayesian modeling workshop with Dr. Kiona Ogle

Bayesian modeling workshop with Dr. Kiona Ogle
Paris, 30 & 31 January, 2017

Summary: This workshop will provide a brief introduction to Bayesian and hierarchical Bayesian modeling. It includes presentation and discussion of basic concepts, including important elements of Bayesian statistics and hierarchical Bayesian modeling. Participants will have the opportunity to develop and implement a Bayesian model in OpenBUGS (in R).

Description: Ecologists are often faced with analyzing relatively complicated data. For example, ecological data sets can be spatially, temporally, or hierarchically structured; they may be missing relevant information; and they likely arise from nonlinear and/or non-Gaussian processes. Additionally, many contemporary problems in ecology require the synthesis of multiple sources and types of data. To accommodate this complexity, Bayesian and hierarchical Bayesian statistical methods are emerging as powerful tools for analyzing such data. This two-daylong workshop will provide an overview of Bayesian modeling at a relatively introductory level. This includes presentation and discussion of basic concepts, including important elements of Bayesian statistics and hierarchical Bayesian modeling. We will also provide an OpenBUGS (Bayesian software package) demonstration. During the workshop, participants will have the opportunity to develop and implement a Bayesian model based on a selection of ecological problems and data. By the end of the workshop, participants will be able to understand the fundamentals of Bayesian modeling and develop basic hierarchical models. We will provide reference materials so participants can explore the topics in greater depth. These materials should serve as a jumping-off point for those interested in employing the methods in their own research, or for those who simply want to familiarize themselves with the topic.
