The EURING 2021 Analytical Meeting & Workshop will consist of several sessions -- on most days the conference will take place during a three hour afternoon session from 1600-1900 CET (1500-1800 BST). Below is a preliminary list of the sessions, and the names of the individuals chairing the sesssions. Contact information for individual session chairs can be found here.

Building on the Eurasian-African Migration Atlas: towards robust quantitative analyses of avian movements. - Chair + Plenary: Stephen Baillie

The Eurasian African Bird Migration Atlas is being developed by EURING between 2018 and 2021, working in close collaboration with the Convention on Migratory species. This web-based Atlas will document movement patterns using ringing and tracking data and will include quantitative analyses of migration timing, migratory connectivity, long-term changes in migration behaviour and illegal killing. It is EURING's largest analytical project to-date and will provide critical information to inform migratory bird conservation. In this session we aim to provide an overview of the analytical approaches developed for this project and on developments in the statistical modelling of avian movements. Opportunities to substantially improve our understanding of movement patterns include accounting for spatial and temporal variation in re-encounter probabilities and analyses combining different data sources, including but not limited to ring recoveries, tracking data and occurrence data. Contributions on these topics from anywhere in the world are welcome.

Dispersal. - Plenary + Co-chair: Ana Sanz-Aguilar, Co-Chair Ana Payo Payo.

Dispersal is a key ecological and evolutionary process. It influences the structure, dynamics and persistence of populations as well as the distribution and abundance of species. Moreover, it determines gene flow among populations, thereby it has implications for local adaptation, speciation and life-history trait evolution. The session will focus on dispersal processes operating at different spatio-temporal scales such as: breeding or natal dispersal, nest dispersal, temporal dispersal (e.g. skipping reproduction) or dispersal betweeen wintering sites.

Data integration and population analysis. - Plenary + Co-chair: Sarah Converse, Co-Chair: Elise Zipkin.

Integration of multiple data sources has tremendous potential to strengthen population analyses by reducing both bias and uncertainty in demographic estimates. However, as the number of data sources in an analysis increases, the potential for assumption violations and scale mismatches also increase. This session will demonstrate ongoing developments in data integration from theoretical and applied perspectives.

Population management. - Plenary + Co-chair: Mike Runge, Co-Chair: Anna Tucker.

What are the applied purposes of mark-recapture or occupancy data and all the associated analyses? To help managers make decisions that will affect wildlife populations. In this session, we will explore the use of such data from the standpoint of decision makers, seeking to understand how information flows from data to analyses to decisions, and indeed, how information can flow the other way to influence study design. A decision analytical framework will provide the scaffolding for this session, with case studies to demonstrate the potential for application.

Survival estimation. - Plenary + Co-Chair: Eleni Matechou, Co-Chair: Fernando Colchero.

Survival estimation is a broad term that encompasses different types of data and corresponding models. For example, it can refer to the study of senescence when following individuals across years, of retention when monitoring length of stay at breeding or stopover sites or of persistence of species at surveyed sites. The session will explore the latest approaches for estimating survival and the associated findings in this broad sense of the term.

Integral projection modelling. - Plenary + Co-Chair: Floriane Plard, Co-Chair: Emily Simmonds.

Demographic rates (survival and reproduction, immigration, and emigration) are directly influenced by functional traits. For instance, large individuals or the ones with territories of high quality often have higher survival and reproductive success than other individuals. Integral projection models (IPM) are population models describing the dynamics of a population through the dynamics of the distribution of one or more functional continuous traits in the population. Different functional traits such as body mass, body size, laying date or birth date have been used to describe the dynamics of different populations. Including the link between functional traits and demographic rates in population dynamics has created a better description of the mechanisms that shape population dynamics. Moreover, selective pressure acting on these continuous traits, as well as phenotypic plasticity, can be modelled. These models are thus particularly interesting for the study of eco-evolutionary dynamics and continuous feedback between individual traits, population dynamics and evolution. This session will focus on how IPMs have created a better understanding of the mechanisms that shape population dynamics in various living species.

Animal movement - Plenary + Co-Chair Roland Kays, Co-Chair: Franny Buderman

The ability to move across the landscape is what makes animals so exciting and ecologically important. It is also what makes them so difficult to study and manage. Our capacity to collect and describe animal movement data has grown exponentially, which has created new opportunities for discovery, but also new challenges for statistical modeling, data management, and integration into management plans. This session will discuss solutions to these challenges and the discoveries their solutions have enabled.

Spatially-explicit capture-mark-recapture analysis. - Plenary + Co-Chair: Richard Chandler, Co-Chair: Andy Royle.

Spatial capture recapture models are models for individual encounter histories that integrate spatial information about sampling with spatially explicit population processes and landscape structure. As such they provide a unifying framework for population and landscape ecology. The application of SCR models has grown rapidly in recent years and they are now routinely applied to estimate density and to address questions of spatial population ecology.

Proceedings

There will be online proceedings in the form of a commented publication list directly accessible from https://euring.org/meetings/analytical-meetings/analytical-meeting-proceedings. Therefore, we kindly request all contributors to have a manuscript ready to be submitted or have their manuscript recently submitted at the time of the conference. Submission deadline will be 1 September 2021. The authors are free to choose any journal, preferred are peer-reviewed journals but also preprint journals such as bioRxiv (https://www.biorxiv.org/) are possible. We will finalize the publication list from the proceedings on 1 June 2022. All contributors are kindly asked to help with the peer-review process by serving as a reviewer. A list with contacts of conference participants/contributors will be provided from which authors can suggest as reviewers to a journal editorial office.
