Netherlands Annual Ecology Meeting

Tuesday 12 & Wednesday 13 February 2019

Conference Centre "De Werelt", Westhofflaan 2, Lunteren, The Netherlands


Each year, on the second Tuesday and Wednesday of February, the Netherlands Ecological Research Network (NERN) organises her annual conference, the Netherlands Annual Ecology Meeting (NAEM). This conference is particularly geared towards people working in the field of ecology and/or evolution. It aims to strengthen the network of ecologists in the Netherlands, Belgium, and surrounding countries and provides an overview of the work carried out by the people in the network. The NAEM meeting is two full days, each day consisting of a plenary session, in which a Dutch/Flemish and an international world leader present their view on a specific topic in ecology or evolution, two sets of five parallel sessions (including more workshop-like sessions), and a poster session. Parallel sessions generally consists of 6 oral presentations, thus leading to a total of approximately 125 oral presentations. On average, we have about 75-100 scientific poster presentations during the meeting. On Tuesday evening, a more relaxed and thought-provoking presentation is generally scheduled. The NAEM meeting is organised in collaboration with the Dutch-Flemish Ecological Society (NecoV) and is financially supported by the Netherlands Organisation for Scientific Research (NWO).

This year will be the 12th edition of the Netherlands Annual Ecology Meeting (NAEM). As always, the meeting will be held at Conference Centre "De Werelt" in Lunteren. At this stage, the four plenary speakers have been confirmed. The first plenary session will be about "Rewilding in the face of Global Change", with plenary talks by Prof. Jens-Christian Svenning of Aarhus University in Denmark, about "Trophic rewilding – background, opportunities and challenges for megafauna-based restoration in the Anthropocene", and by Dr Liesbeth Bakker of the Netherlands Institute of Ecology, about "Rewilding: impact on ecosystems under global change". The second plenary session will be about "Estuarine & Coastal Ecology in the Anthropocene: challenges and opportunities", with plenary talks by Prof. Laura Airoldi of the University of Bologna in Italy, about "Discovering, understanding and sustaining marine ecosystems along increasingly artificial coastlines", and by Prof. Tjeerd Bouma of the Royal Netherlands Institute for Sea Research, about "Sustaining intertidal ecosystems under climate change for coastal protection". Below, you can find more details about the general set-up of the programme and about the deadlines for submission of contributions to the 2019 NAEM meeting. You are cordially invited to register your participation.

  Plenary 1: “Rewilding in the face of Global Change”
Throughout human history, global wildlife loss (defaunation) has disproportionally affected large animals and the functions they have in ecosystems. Rewilding aims to restore these functions through the re-introduction of missing, large wildlife species. However, rewilding can also be applied through the restoration of water level dynamics in ecosystems. In this session, we focus on the concepts, opportunities and impacts of rewilding as a restoration approach in the face of global change.

  This session is linked to the first plenary session on Rewilding in the face of Global Change. Throughout human history, global wildlife loss (defaunation) has disproportionally affected large animals and the functions they have in ecosystems. Rewilding aims to restore these functions through the re-introduction of missing, large wildlife species. However, rewilding can also be applied through the restoration of water level dynamics in ecosystems. In this session, we focus on the ecosystem consequences of defaunation as well as the impacts of rewilding as a restoration tool. Ecological genomics is an emerging interdisciplinary field of studies that seeks to understand the molecular mechanisms underlying responses of organisms to their natural environments. In this symposium, we will bridge the gap between ecology and genomics by exploring the potential of ecological genomics in model and non-model organisms. We will do that by exploring the benefits that ecological genomics brought to, among others, the following three areas of research: 1) the study of life history evolution and its impact on the genome architecture; 2) the genomic mechanisms of phenotypic plasticity, and 3) the genomic bases of adaptation and speciation. During the last three decades of research on BEF, we have accumulated evidence of the positive effects of biodiversity at small scales on ecosystem functioning. This session will highlight current and future directions in BEF research. This includes 1) scaling up the BEF relationship and mechanisms in space and time, 2) clarifying the buffering effect of biodiversity on ecosystem functioning in a changing world, and 3) determining the role of multitrophic interaction in driving BEF. Fitness and population dynamics are inter-related topics: fitness is about who survives and reproduces whilst population dynamics concerns how the size and structure of populations is driven by variation in demographic rates. In this session, we aim to unite long-term studies conducted at the level of individuals. By comparing factors explaining variation in survival, growth, fecundity and dispersal, we can advance our understanding of how individual fitness scales up to population dynamics. In the current time of rapid global change in climate and societies, conserving nature and natural processes has become an ever increasing challenge. In this session we (1) highlight examples of ecological research that evidently have a positive impact on the conservation of a species, habitat or ecosystem, and (2) explore avenues of future ecological and/or other research to contribute to more resilient conservation of nature and a sustainable society.

  There is ample evidence that the world is changing more rapidly than ever before as a result of direct and indirect human influence. In fact, changes are occurring so fast that we as ecologists can study the way organisms are responding to these changes. In this session, we want to show examples of animals trying to cope with these changes by behavioural, physiological or somatic changes. Using modern technology, we have become nature’s followers: we can camera trap every animal that lives in an ecosystem and gps-track individuals over long periods of time. In this session, researchers will present what they are monitoring, how and why they are doing this, and how the excessive amounts of obtained data are analysed. Urban ecosystems cover a small but continuously increasing proportion of land surfaces, and tend to differ greatly from natural or rural areas in several biogeochemical/physical drivers of biodiversity and ecosystem functioning. Urbanisation therefore imposes a strong selection pressure and environmental filter. Because it is a global phenomenon, it provides a unique opportunity to study adaptive strategies of species towards often extreme human impacts like pollution, fragmentation and warming. We welcome contributions that aim to achieve an integrated understanding of the ecological and evolutionary dynamics of species in urban environments, especially those that advance insights into the processes that characterise winner species. Fungi are known for their detrimental (e.g. parasitism) and beneficial (e.g. mutualism) interactions with other organisms and even for switching their interaction type when environmental conditions change. Thereby, their ecological role can greatly change, resulting in different food-web interactions and ecosystem level outcomes. The aim of this session is to highlight the ecological role of terrestrial and aquatic fungi in ecosystem processes, the diversity and variability of their interactions and their response to environmental change. Ecosystems can be significant carbon sources or sinks depending on their management. There is a growing concern that ecosystems will increasingly function as CO2-source as climate warms and nutrient enrichments increase. Concurrently, initiatives as 4p1000 claim that a slight increase in ecosystem C-sequestration could fully compensate anthropogenic increases of atmospheric CO2. This session provides a platform for a wide range of studies on carbon and nutrient dynamics in the context of climate change mitigation.

  Annual cycles consist of breeding and non-breeding periods that are often clearly separated in space and time, but that are biologically intricately linked. These inter-seasonal effects are poorly understood but are crucial to understand population dynamics and space use, making full annual cycle research important for effective conservation and management. This session examines how environmental conditions and individual state in one season carry over to influence the performance in the subsequent season, and what the consequences of these seasonal interactions are. In the cultural landscape there are obvious fields of tension between human interests and highly abundant herbivores. Mitigation of problems may be achieved a.o. using technical measures, the influencing of animal behaviour, or more or less carefull population management. This session aims at providing a platform for studies that test and develop theory or practical instruments for wild-life management, as well as case studies where the scientific basis and effectivity of actual management decisions are being evaluated. In terrestrial ecosystems, soil organisms  are involved in a series of important ecological processes and functions, such as nutrient cycling, support of plant growth, degradation of pollutants and buffering against acute environmental changes. In this session, we focus on the ecological and functional role that (micro)organisms play in soil ecosystems. The potential of contemporary evolution to lead to rapid trait change is increasingly being recognized. Microevolutionary dynamics can be so fast as to affect the outcome of species interactions, geographic range shifts and the stability of populations and communities. By presenting in-depth case studies on a wide variety of organism types, this session will illustrate how rapid evolutionary change provides a pathway to a broad range of ecological dynamics. Big data in ecology is pushing new boundaries for ecological analyses, but it also brings novel pitfalls and dangers. Global datasets offer a grand opportunity to disentangle the governing dynamics of ecosystems, but it also sets novel challenges: the need to develop efficient analytical tools and new evidentiary standards to prevent spurious correlations. How to deal with these challenges and where to go from here? How do we go from big data to best practices?

  Coastal sees, such as the North Sea, provide us with food, protection, and recreation possibilities and are valued for their ecological wealth. Simultaneously, these systems are increasingly threatened by global change, rising world populations and coastal urbanization. To conserve these ecosystems, scientific knowledge of mechanisms and processes driving coastal ecosystem degradation is essential. In this session, we provide a platform for scientific research that supports evidence-based conservation, sustainable management and habitat restoration of coastal seas. In ecology, we try to understand the relationship between organisms and their environment at different scales: from local populations to meta-communities to global patterns in biodiversity. While research questions may change with scale, the data that is used in analyses remains the same. In this session, we focus on how small-scale data is used to answer macroecological questions, and aim to highlight the relevance of large-scale studies for improving our understanding of general ecological concepts. This session deals with studies focused on tropical ecosystems, including terrestrial as well as marine systems. We particularly welcome talks focused on explaining the extraordinary high biodiversity, or on understanding anthropogenic impacts on this diversity. The spatial distribution of organisms is still largely unknown, either due to lack of quantitative data in general, or to the lack of harmonization of existing data sets. Harmonization necessitates knowledge on both biological methods and spatial statistics and databases. Linking spatial patterns in organism distribution to environmental properties and management lead to further understanding of these patterns. Talks covering these issues in the spatial distribution of soil-, aboveground or aquatic organisms are welcome. The microbiome is highly complex and flexible, and can respond rapidly to changes in host genotypes/diets or (a)biotic environmental disturbance, e.g. via chemical communication. Host associated microbiomes may thus represent an important source of metabolic flexibility for the host and comprise interactions among individuals inside a specific community. In this symposium, we aim to understand interactions between microbiomes and host genetics, microbiome mediated local adaptation, microbiome interactions at the community level and what the implications are for host ecology and ecosystems in general.
