Nereis Park VI
The aim of this event is to bring together the international scientific community of researchers working on the mechanisms of bioturbation in marine, freshwater and terrestrial environments, at all latitudes (polar, tropical, temperate), and taking different time scales into account (from Precambrian to present). This event is organized by the Nereis Park association, an international association gathering all scientists working on Bioturbation .
This 6th edition proposes an international thematic school on Bioturbation with conferences and with high-level training with the aim of giving scientists and students the latest conceptual and technological advances on bioturbation processes. This event will concern these processes as a whole and their impacts on ecosystem functioning, at different spatial and time scales.

5 sessions
Session 1: Bioturbation-ecosystem relationships
Keynote lecture: Pr. Murray Gingras | Univ. Alberta, USA
In this session, the role of bioturbation for ecosystem evolution will be discussed with particular focus on the various ecosystem services provided by bioturbation in terrestrial, freshwater and marine ecosystems in the context of global change. The various effects of bioturbation will be addressed including: sediment erosion, stabilization and drainage, biogeomorphology, contaminants and cysts releasing, oxygenation and bioremediation of polluted sediments and soils, organic matter recycling. For the first time in a NP conference, functioning of past and extreme environments (Precambrian, Quaternary caves, mangroves, polar and deep environments, hyper-saline lakes…) will be considered.
Session 2: Integration of bioturbation processes into biodiversity patterns and functions
Keynote lecture: Dr. Andrew M. Lohrer | NIWA, New Zealand
The influence of bioturbation activities on ecosystems depends on benthic structural and functional diversity, strongly linked to environmental variables. This session will address different approaches (i.e., species, functional diversity, biological traits…) for evaluating the effects of biodiversity on ecosystems functioning, through experimental and field studies. This will be the initial statement for an open forum session based on two questions:
- How do we integrate the role of individual species characteristics on benthic processes at the community scale?
- How do we upscale the effects of benthic communities at the ecosystem level?
Session 3: Micro/macro-organisms interactions for the biogeochemical cycles
Keynote lecture: Dr. Wiebke Ziebis | Univ. Southern Carolina, USA
Bioturbation activities modify microbial diversity and processes involved in the sediment organic matter degradation and recycling. The latter have an influence, at larger scales, on biogeochemical fluxes and budgets (carbon, nitrogen, sulfur, phosphore, silica, iron). Organic matter quality (refractory versus labile) and environmental variables drive the benthic microbial processes. This session will focus on the interactions between the micro-organisms (e.g. procaryotes, cable bacteria, archae, eucaryotes and co-occurrence networks) and macro-organisms involved in sediment biogeochemistry
Session 4: New approaches of observation, analysis and modeling for bioturbation studies
Keynote lecture: Dr. Simone Pennafirme | Univ. Federal do Fluminense, Brazil
This session will focus on the different tools allowing to deal with ecosystem heterogeneity:
- 2D optical and infrared sensors, to measure micro-heterogeneity of solutes in porewaters (oxygen, manganese, sulfur, CO2, pH…)
- Biogeochemical fluxes at the sediment-water and sediment-air interfaces
- Remote sensing to visualize microtopography and benthic diversity at the sediment surface
- Tomography imaging, to visualize in 3D biological structures within sediments and soils
- Mechanistic and stochastic models to simulate biogeochemical processes associated to animals behavior.
We will also consider the potential limitations of these tools, and how they can be overcome for specific field study or experimental set up.
Session 5: Scales transfer
Keynote lecture: Pr. Robert C. Aller | Stony Brook University, USA
Integrating the outcomes of the conference and the wokshops of the thematic school, this session will focus on downscaling and upscaling (scale transfer) referring to:
- the importance of a specific bioturbation process within diagenetical models;
- the representation of the species or functional traits in the community;
- the transfer from controlled experiments to in situ studies integrating the ecosystem as a whole;
- extrapolation of results obtained from a local study at ecosystem level taking into account its spatial and temporal variability.
Thematic school objective
This event will offer different and complementary tools in each session (courses and case studies as form as keynote lecture and short talks, respectively, practical works in the field and in the lab, open forum session, round tables..) to understand the role of bioturbation in the current and past functioning of ecosystems, and to know how to integrate it into ecosystem models, in ecological engineering and ecosystem restoration / management projects. These scientific and educational meetings, by mixing the disciplines, will thus help to build up a network of expertises. This will bring out innovative approaches to answer fundamental and methodological questions. This event is addressed to any scientist (researcher, student, engineers) as well as manager in environmental science.

Accommodation
This event will be held in Brittany (France) at Logonna-Daoulas, from the 23rd to the 28th of August 2020, at “Moulin Mer”. This facility provides space for sessions and workshops, meals and accommodations, all at one location, including access to educational rooms and to sampling sites in marine, freshwater and terrestrial environments. For your spouse, it also provides access to nice walks along the beaches, forest, and places for activities such as volley ball, badminton, sailing, and fishing.
The site is located between Brest and Quimper (at 8min from the expressway). Brest is the closest city with a train station (TGV) and an airport offering a handful of international flights and many direct flights from Paris (Orly or CDG).
Abstract call
Each of the five sessions is composed of invited talks, a (limited) set of oral presentations (selected from the abstracts), a poster session, round tables and specific practical and theoretical classes for revised concepts and methods training.
The Scientific Committee of this event invite the participants to submit an abstract in English to one of the following sessions:
- Session 1: Bioturbation-ecosystem relationships
- Session 2: Integration of bioturbation processes into biodiversity patterns and functions
- Session 3: Micro / macro-organisms interactions for the biogeochemical cycles
- Session 4: New approaches of analysis, observation and modeling for bioturbation studies
- Session 5: Scales transfer
The preference for oral/poster and the choice of the thematic session are options indicated on the abstract submission form. Motivations and expectations for participating to the thematic school should be added to the pre-registration form.

The abstracts will be selected by the international scientific committee. Once your abstract selected, you can fill the final registration form which includes the payment details. Your registration will be official when payment of the registration fee is received.
