Profil

Zusammenfassung

Dr. Papageorgiou erforscht, wie Entscheidungen in Tiergruppen getroffen werden — insbesondere wer Einfluss hat, wie Dominanzhierarchien funktionieren und wie Gruppen koordiniert vorgehen. Sie nutzt GPS-Tracking und Netzwerkanalysen, um zu verstehen, wie individuelle Verhaltensweisen soziale Strukturen prägen und umgekehrt. Diese Expertise ist praktisch relevant für alle, die Gruppenverhalten, Koordination oder Hierarchien in komplexen Systemen verstehen oder beeinflussen möchten.

• Inferring influence and leadership in moving animal groups

  2018

  Philosophical Transactions of the Royal Society B Biological Sciences · 161 Zitationen · DOI

  Collective decision-making is a daily occurrence in the lives of many group-living animals, and can have critical consequences for the fitness of individuals. Understanding how decisions are reached, including who has influence and the mechanisms by which information and preferences are integrated, has posed a fundamental challenge. Here, we provide a methodological framework for studying influence and leadership in groups. We propose that individuals have influence if their actions result in some behavioural change among their group-mates, and are leaders if they consistently influence others. We highlight three components of influence (influence instances, total influence and consistency of influence), which can be assessed at two levels (individual-to-individual and individual-to-group). We then review different methods, ranging from individual positioning within groups to information-theoretic approaches, by which influence has been operationally defined in empirical studies, as well as how such observations can be aggregated to give insight into the underlying decision-making process. We focus on the domain of collective movement, with a particular emphasis on methods that have recently been, or are being, developed to take advantage of simultaneous tracking data. We aim to provide a resource bringing together methodological tools currently available for studying leadership in moving animal groups, as well as to discuss the limitations of current methodologies and suggest productive avenues for future research. This article is part of the theme issue ‘Collective movement ecology’.

• The importance of individual‐to‐society feedbacks in animal ecology and evolution

  2020

  Journal of Animal Ecology · 139 Zitationen · DOI

  The social decisions that individuals make-who to interact with and how frequently-give rise to social structure. The resulting social structure then determines how individuals interact with their surroundings-resources and risks, pathogens and predators, competitors and cooperators. However, despite intensive research on (a) how individuals make social decisions and (b) how social structure shapes social processes (e.g. cooperation, competition and conflict), there are still few studies linking these two perspectives. These perspectives represent two halves of a feedback loop: individual behaviour scales up to define the social environment, and this environment, in turn, feeds back by shaping the selective agents that drive individual behaviour. We first review well-established research areas that have captured both elements of this feedback loop-host-pathogen dynamics and cultural transmission. We then highlight areas where social structure is well studied but the two perspectives remain largely disconnected. Finally, we synthesise existing research on 14 distinct research topics to identify new prospects where the interplay between social structure and social processes are likely to be important but remain largely unexplored. Our review shows that the inherent links between individuals' traits, their social decisions, social structure and social evolution, warrant more consideration. By mapping the existing and missing connections among many research areas, our review highlights where explicitly considering social structure and the individual-to-society feedbacks can reveal new dimensions to old questions in ecology and evolution.
