A Tale of Two Butterflies: The Effect of Larval Social Environment and Circadian Rhythms on Mating Behavior in Bicyclus anynana and Heliconius hewitsoni
… research focuses on using butterflies to explore kin recognition from the larval stage and its possible impacts on adult mate choice and if courtship is circadian in Heliconius hewitsoni. My first experiment concerned kin recognition. When inbred, Bicyclus anynana are known to suffer from …

Social behavior and kinship in the four-toed salamander, Hemidactylium scutatum
… interaction between relatedness and dispersal (kin discrimination) and the potential for phenotypic traits to be used as a mechanism for kin recognition. I combined empirical observations with lab experiments to (1) examine population structure in H. scutatum (Chapter 1), (2) determine if …

Computer simulations of kin selection
The theory of kin selection is central to the understanding of social evolution. Recent theoretical work suggests a limitation on the action of kin selection in structured populations. The first such limit involves a specialized population structure, termed "budding viscosity," common to social …

Kindliche Körpergerüche als Chemosignale in der Mutter-Kind-Beziehung
Eine sichere Bindung zwischen Mutter und Kind in den ersten Lebensjahren ist prägend für die Entwicklung eines Kindes. Die Qualität dieser Bindung ist ein wichtiger Prädiktor für langfristige physische und psychische Gesundheit. Für den Aufbau einer starken Bindung ist die Investition von …

Odour signals contain multi-modal information in the banded mongoose (Mungos mungo).
… how they may facilitate reproductive decision-making in the banded mongoose (Mungos mungo). I use a wild but habituated population to conduct experimental odour presentations showing these mammals are capable of discriminating scents based on sex, familiarity, relatedness and female reproductive …

Evolution of Altruism and Eusociality: Toward a Cost/Benefit Analysis of Fitness and Genetic Relatedness
… this modeling framework, inclusive fitness thinking leads to insights that completely change these conclusions. I showed that relatedness and inclusive fitness indeed are causal and that eusociality does evolve more readily. With regard to the latter this means eusociality can be favored under a …

Factors influencing aggression in newly mixed pigs
… and the basis on which a pig accesses recognition and familiarity when mixed with an unfamiliar pig. The hypothesis that fighting in newly mixed pigs is proximately triggered by an innate response to fight unfamiliar pigs as opposed to an alternative hypothesis that fighting is …

The evolution of exploitation through mimicry
… relies on previous work on social selection, kin recognition, and tag-based cooperation, which together suggest that mimicry, when successful, is likely to be an evolutionarily beneficial strategy for signallers. Insofar as receivers confer cooperation to those signallers with whom they …
