Lea Rausch gave a talk at the European School on Ostracoda

3rd European School on Ostracoda, Jena (Germany), 19th – 23rd March 2018: An introduction to Ostracoda

by Lea Rausch

The European School on Ostracoda is designed to provide an overview of the taxonomy, (palaeo)ecology, biodiversity, geological history and applied biostratigraphy of ostracods. It is intended for young scientists and industrial staff interested in micropalaeontology, palaeoceanography, palaeoclimatology, biology and environmental applications. The 3rd round of the course focussed on methods and concepts of ostracodology including systematics, biostratigraphic applications, ecology and life history spanning their fossil record from the Paleozoic to the Holocene and covering the recent fauna as well. Case studies from marine and continental systems as well as practical training for identification, preparation, documentation and analysis have been an important part of the course.

For the first time this year ostracoda of Paratethyan origin were thematically highlighted and introduced by Marie-Curie Early Stage Researcher Lea Rausch. The endemic ostracod assemblages from the Paratethys play a significant role in reconstructing the paleoenvironmental evolution and connectivity in between semi-isolated basins of the Pontocaspian region. An upper Miocene ostracod assemblage from the Denizli Basin (SW Anatolia, Turkey), was used to give paleogeographic implications and helped to elucidate the role of the satellite region as source/sinks area of Pontocaspian biota.

The next course, which takes place at Friedrich Schiller University in Jena (Germany) in Spring 2019, is primarily intended for young researchers at the PhD or MSc. stages of their careers and industrial staff who intend to work with ostracoda. The course is financially supported by the “Society of Friends/Förderverein IRGO e.V.”. For further information visit

Sri presented a poster at AGU fall meeting

Sri Nandini presented a poster at the fall meeting of the American Geophysical Union (AGU), 11 to 15 December 2017 in New Orleans. The aim of the poster talk was to show the audience how global climate affects the regional climate of the Caspian basin like precipitation and evaporation over the time scale of 1850-2100 with the help of a climate model. Sri is working at the Center of Marine Environmental Sciences (MARUM) of the University of Bremen. She helped to represent Marum at its booth and this was advertised at their website.

Sri Nandini joined the UN Climate Change Conference and was interviewed

Sri Nandini joined the UN Climate Change Conference (COP), 6-17 Nov 2017, in Bonn, Germany. The conference was chaired by the Presidency of Fiji, Prime Minister Frank Bainimarama.

He said: "I intend to act as COP President on behalf of all 7.5 billion people on the planet. But I bring a particular perspective to these negotiations on behalf of some of those who are most vulnerable to the effects of climate change - Pacific Islanders and the residents of other SIDS countries and low-lying areas of the world. Our concerns are the concerns of the entire world, given the scale of this crisis.".

Aside from that Sri Nandini was interviewd in BUS, the journal of the University of Bremen. At page 7 you will find the interview with Sri, in German.

International Conference on Aquatic Invasive Species

Anouk D'Hont gave a talk at the International Conference on Aquatic Invasive Species (ICAIS2017) on 23 October 2017.

This is a link to the program and abstracts.

The introduction and spread of invasive species in freshwater and marine environments is a worldwide problem that is increasing in frequency.

There are various pathways by which non-indigenous invertebrate, fish, and plant species are introduced, become established and cause significant damage to coastal and freshwater ecosystems, and to the economies that depend upon them. Next to habitat loss, invasive species are considered the greatest threat to native biodiversity.
Our PRIDE-researcher Anouk D'Hont gave a talk:
Do Ecological Interactions Explain Dominance Shift between Ponto-Caspian Bivalves Dreissena polymorpha and Dreissena rostriformis bugensis in their Introduced Range?

The invasive bivalve species Dreissena polymorpha and Dreissena rostriformis bugensis are native to the Ponto-Caspian area (i.e., rivers basins northern of the Black sea, Caspian sea and Azov sea). In the 19th century D. polymorpha started extending its geographical range. Nowadays this species can be found throughout Europe, Eurasia and North America on hard substrates in fresh to oligohaline rivers, lakes and canals. However, since circa 20 years ago the closely related D. r. bugensis too started showing invasive behaviour, causing a dominance shift from D. polymorpha to D. r. bugensis. Although, this is a widely observed phenomenon, mechanistic understanding of displacement of D. polymorpha by D. r. bugensis is still limited. Therefore, we focused on two sites in the Rhine-Meuse river delta where both species co-occurred since 2006. We assessed the ecological interactions within these mixed populations on fouling plates 3, 6 and 12 months after settlement.This may shed more light on the mechanistic understanding of the displacement of D. polymorpha by D. r. bugensis at other sites.

European Marine Science Educators Association

Aleksandre Gogaladze gave a talk at the European Marine Science Educators Association (EMSEA) conference on 10 October 2017. EMSEA is an informal non-profit organisation which provides a platform for ocean education and promoting ocean literacy within Europe. The goals of EMSEA are

  • to stimulate is dialogue between European and international marine educators and scientists
  • to provide training and teaching materials to support marine educators
  • to raise educators awareness of ocean issues and the need for a sustainable futrure for our coasts, seas and oceans

Justine Vandendorpe in Yamal Peninsula

Our researcher Justine Vandendorpe went to the Yamal Peninsula (northwest Siberia, Russia) from 5 to 30 June 2017. She joined a research group studying the decline of the long-tailed duck population. These waterfowls feed on benthic animals such as the mud snail genus Ecrobia that Justine studies. It was an opportunity for this young researcher to look for the mud snail in the Arctic as Ecrobia is suspected to have traveled between Eurasia and North America through the Arctic Ocean. Justine had the chance to discuss that with two local television crews.

Public awareness on biodiversity, attitudes and understanding

Within the framework of projects PRIDE and LIFE for Danube Sturgeons a study has been conducted on the Current public awareness of biodiversity in the coastal areas of the Black Sea. Here are the photographic impressions from Summer Biological Practicum of Richelieu Lyceum (Odessa). In this annual two week field trip, that was held along the Psel River in 2017, 102 lyceum students participated in total representing 7 scientific groups (invertebrate zoology, vertebrate zoology, botany, hydrobiology, soil biology and entomology, physiology, geology). We thank Dr. Mikhail Son from the Institute of Marine biology for his invaluable assistance and contribution.



Outreach in Ukraine and Romania

Aleksandre Gogaladze is currently (May, June 2017) traveling around Ukraine and Romania. His plan is to interview the stakeholder institutions to gather data on their social network structures in order to understand how Pontocaspian biodiversity related environmental issues are shared and communicated among different actors in Ukraine and Romania; Besides, he will work on promoting the PRIDE citizen science through the taxonomic identification sheet. Here are his first impressions from Romania.

I arrived in Bucharest a week ago from Ukraine loaded with new experiences and positive emotions. I had a very productive 2 weeks in Ukraine and thanks to PRIDE’s Ukrainian partners I managed to interview 11 stakeholder institutions. Also thanks to the Ukrainian hospitality I was invited on excursions in 3 different protected areas on the Black Sea coast where I met the directors of protected areas and also representatives of different conservation organizations. Apart from interviewing them we had fruitful discussions about conservation problems in general that Ukraine is currently facing and also about different possibilities of leaflet distribution and citizen science promotion on protected areas.

 I spent most of my 2 weeks in Kherson, however before going to Kherson I stayed in Kiev for several days and met PRIDE’s partner institutions: Prof. Vitaliy Anistratenko from the Institute of Zoology and Ms. Natalia Gozak from WWF Ukraine. We discussed and planned the future steps together and they helped me with contacting the stakeholder institutions.

It is already one week I am in Bucharest, Romania. I have interviewed 3 institutions here so far and there are many more planned meetings to come before I go back to Ukraine for my secondment at WWF Ukraine. I met with PRIDE’s Romanian partner institutions: Prof. Marius Stoika from the University of Bucharest and Dr. Luis Popa and Dr. Oana Popa from the Grigore Antipa Museum. They were very helpful with putting me in contact with stakeholders and thanks to them I have many meeting fixed.

Besides, I and my fellow ESR colleagues: Alberto Martínez Gándara and Lea Rausch have very exciting plans on engaging with Black Sea Coastal schools and Universities and raising awareness and promoting citizen science amongst students using our leaflet. In Romania, with the assistance of Ana Bianca Pavel from INCD GeoEcoMar, we already have fixed meeting in Constanta with 5th grade school students from 2 different schools on May 30th. This will be a one day extra-curricular activity where we will explain the school students about the importance and uniqueness of Pontocaspian biota and we will enlighten them on how they can help us using the leaflet to generate the actual scientific data on species occurences.

Another good news is that with the great support of Ms. Natalia Gozak from WWF Ukraine we have already introduced our leafelts into 20 Black Sea Boxes that will be distributed around schools in Ukraine. Also, Ms. Natalia Gozak suggested to dedicate 1 day to PRIDE from the Ichthyological field work that WWF Ukraine is organizing for Kherson University students. The fieldwork will take place in Danube Delta Biosphere Reserve, in Vilkovo area, Odessa Region and the day for PRIDE will be on June 27. We have asked for expert assistance from Dr. Mikhail Son from the Institute of Marine Biology in Odessa and fortunately he is willing to accompany us on the fieldwork on June 27 and represent PRIDE together with me, Lea and Alberto. Our intentions are to enlighten the students on the uniqueness of Pontocaspian biota and importance of Pontocaspian mollusks in food webs as a food source for Sturgeon and other Pontocaspian fish species. The theory will be accompanied by a fieldwork at the end of the day and we intend to use our leaflets to show students different species assemblages in different environments (marine, estuarine, freshwater).

Climate Models: Mirages for Virtual Climatic Realities

“All climate models are wrong, but some are useful” Statistician George Box (1919-2013).

I am a climatologist. I use a climate model. This is my laboratory where I perform all my experiments.

This doesn’t mean I bounce a jelly Mini-Earth in the lab, it means I describe Earth’s climate system through a climate model made of several computer programs to create a virtual Earth. Inside this virtual reality, I aim to understand the changing processes on the Earth’s climate system through. Processes like clearing farming land to build cities for a larger population in Brazil or intense deforestation in Indonesia. Others including more/less industrial emissions into the atmosphere/ocean creating fog and pollution in China or India or the extent of Antarctic/Artic sea ice & sea-level rise in Tuvalu. This is the only tool I have to better understand our system; because I cannot conduct large scale experiments on the vast atmosphere itself; nor am I a time traveler (to see past/future changes). Is this concept so different from playing computer games like MY2050, CO2FX or SimCity?

The climate model (collection of math equations to describe the different (physical, chemical, geological) processes that drive the Earth’s climate) is run on a supercomputer; demanding huge amounts of expensive computational resources. The science of climate modelling stems from laws of physics (like Newton & and laws of thermodynamics). Each equation contains many variables like temperature, rainfall, sea-level rise, and when we combine all these equations, through individual & collective interactions, we see how the climate evolves (atmosphere, ocean, land, sea ice & the sun) from the North Pole to the Kiribati Islands (equator) and the South Pole. This is a complex & daunting task. 

Fig 1: Running computer codes and checking experimental outputs via remotely connected to the supercomputer 

Information of processes are resolved by 3 dimensional grid boxes (cubes) called spatial model resolution (pixels/ grid points) with larger grids at the equator and smaller at the poles (which can be made of several kilometers). A 2-degree spatial resolution specifies horizontal grid box of ~ 210km but even at 1-degree horizontal resolution (111km) it is still too coarse (Fig2) to capture finer processes like ocean eddies/ topography (mountains) or evaporation over the Easter islands. Choices for resolution depends on available computing power and the time needed to run the model experiment. In the current golden age of high resolution (smaller grids), the more complicated & higher resolution a model, the slower it is on the supercomputer. Choices are made in every aspect of building, running and analyzing climate models for efficiency. But as climate models (regional to global scales) span longer periods (years, decades, or millennia) than weather models (local scales), they cannot include as much detail. Most scientists agree that high-resolution models were far better at reproducing observational data (e.g. from satellite or gauges) & intense storms, cyclones & hurricanes (fine scale climate events). This is not always true. But to have a perfect simulation of reality, climatologists need understanding of each process (every cause and effect). A question to ponder, won’t there always be processes we don’t fully understand but think are important? Processes like clouds which are on smaller resolutions then model. When we achieve the finest resolution, would these climate models be simulators of reality then? 

Modern day climate model descendants from the first pioneering model (1960s) at NOAA Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey have improved vastly. These models agree/disagree with each other due to choices made when incorporating elements in building each model, such as the treatment of clouds, aerosols and the carbon system. This gives a different virtual reality each time. The Community Earth System Model (CESM1.2.2) is one of these ~30 climate models. The CESM is unique as it is developed by a broad community of scientists & freely available to researchers worldwide. It encompasses a much improved holistic science on major components of the climate system. This gives a better representation of the Earth’s climate system. Using the CESM, I hope to learn more about large scale ocean-atmosphere teleconnection patterns such as the North Atlantic Oscillation and the El Nino Southern Oscillation. These affect sea surface temperatures as well as atmospheric conditions such as change in pressure and winds which are responsible for rainfall. This can lead me to understand the past extreme events or predicting future years of potential impacts, like a high probability of drought (warm and dry) for the Caspian. Or several years of cold and wet conditions (flooding) with catastrophic implications for local people, agriculture & economy through time.

How do climate modellers predict the future?

We do not.

Predicting the future is impossible. Instead we make climatic projections for a set of different possible futures (creating virtual realities) based on physics and predications of future CO2 and other emissions. When modelling a century for these virtual realities, even the 5th Intergovernmental panel on climate change (IPCC) offers “what if” projections of future climate scenarios that relate to certain emissions scenarios. Inside this virtual reality, I can tell how hot the next 5-10 summers will be, but not how hot a weekday in that one summer. There are limitations; even inside this virtual reality.

We make assumptions on how the earth system works. These assumptions are simplified, because the climate is complex and computing power limited. The truth is complex and models are merely an approximation of the truth. With a little bit of patience, time, more data to work with and more powerful computers, climate models will improve through advanced scientific understanding of Earthly processes. But skeptics continue discrediting climate models, basing it on crudity & simplification reflected in reality. Hence, rather than viewing models as the literal truth, we should view it as alternate realty which is something useful. As featured in Before the Flood documentary, Piers Sellers, the British born astronaut, acclaims that “as the science community, we have not done the best job, frankly, of communicating this threat to the public. When you go up there and see it with your own eye, you see how thin the world’s atmosphere a tiny little onion skin around the Earth”.

Climate modellers, as humans, have limits to their scientific understanding and computing power, hence “all models are wrong” because they are a simplification of reality “… but some are useful.” These simplifications are the only tools to explain, predict & understand the climatic process on Earth. Does a climate model have to be perfect to be useful? The hard part is assessing whether a model is a good tool for the job at hand. So the question for my next blog is:

How do we assess the usefulness of a climate model (CESM); for the Caspian in particular? We show ways to quantify climate modelling uncertainties and its impacts, past and future.
