Sociality is both widespread across taxa but rare ac ross species\, making careful study of the cost and benefits constraining and driving the evolution of social systems both enticing and paramount if we are to understand how solitary organisms form simple families\, and ho w more coherent groups make the transition into permanently social superor ganisms such as eusocial insects. Sociality is thought to thrive in face o f environmental adversity\, but because social structures are frequently c haracterized by high organismic density\, close relatedness\, and frequent physical interactions\, infections can spread rapidly and are considered one of the greatest hurdles during social evolution. To overcome this thre at\, individuals in groups can not only increase their investment into per sonal defenses\, such as physiological and behavioral immunity\, but also exhibit communal defenses which have been described as collective or socia l immunity. Recent studies have suggested that this communal defense plays a key part in the early emergence of sociality &ndash\; yet little is kno wn about the role of collective defenses in primitive groups\, such as fac ultative family associations where offspring benefit from parental care\, but do not require these benefits to survive. In particular\, it remains l argely unknown to what degree collective immunity in subsocial species is mediated by parental care or how it shapes investment into personal immuni ty in these family groups. Similarly\, whether or not the increased risk o f pathogen spread hinders the gregarious nature of facultative family asso ciations or facilitates it by selecting for cooperation is not yet underst ood. I aim to shed light on these issues by investigating individual and c ollective pathogen and parasite defenses and their associated costs and tr ade-offs with life-history traits in a model system featuring species of v arying dependence on parental care. Beetles of the genus Nicrophorus boast offspring ranging from completely independent to utterly helpless without parental assistance. By comparing the impact of both pristine and harsh e nvironments\, I hope to reveal to what degree offspring &\; parental ad justments to care and pathogen threats shift with varying dependence on ca re\, and whether these changes are reflected in overall fitness and indivi dual pathogen resistance. Overall\, my research will attempt to reveal key interactions between personal &\; collective efforts to best adverse c onditions with the consolidation of facultatively social individuals into interdependent social systems.\n***\n- new member in BayCEER - DTSTART;TZID=Europe/Berlin:20210520T121500 DTEND;TZID=Europe/Berlin:20210520T134500 SUMMARY:Maximilian KörnerDr. Maximilian Körner\, Evolutionary Animal Ecolog y\, BayCEER / University of Bayreuth (Homepage): Investigating communal pa thogen defense and its role in social evolution TRANSP:TRANSPARENT END:VEVENT END:VCALENDAR
