The use of exponential random graph models to explore social foraging dynamics of interspecific songbird assemblages
… random graph models (ERGMs). Developed for the social sciences, ERGMs analyze how network structures (i.e., configurations of edges) and attributes of nodes and edges affect the formation of edges. This allows practitioners to explore how different mechanisms shape networks of interest. In this …

OPTIMAL GROUP SIZE IN HUMANS: AN EXPERIMENTAL TEST OF THE SIMPLE PER CAPITA MAXIMIZATION MODEL
… framework for predicting optimal group sizes in social foraging contexts. Participants engaged in a social foraging task where they chose to forage for points exchangeable for lottery prizes either alone or in a group that has agreed to pool and share all resources equally. In Experiment 1, …

A procedure to test human behaviour under producer scrounger conditions
… used in the biological literature to model social foraging, to human beings. It is argued that humans do find themselves in economically important situations that can be described by the producer scrounger dynamic.

Testing models of the adaptive evolution of consistent individual differences in behavior using sticklebacks
… been implicated in several models: competition, social interactions and environmental uncertainty. Therefore for my dissertation I tested whether these factors influence consistent individual differences as predicted by theory. Additionally, these models make several assumptions about the costs …

Scanning-group-size effect in flocks of house sparrows : quantifying the contribution of competition and anti-predatory vigilance
As social foraging groups increase in size, individual levels of scanning decrease while time spent feeding increases. Traditionally, anti-predatory considerations provide the preeminent explanation for this scanning-group-size effect, but contest and scramble competition could also account for the …

Investigating the physical and ecological drivers of change in a coastal ecosystem: from individual to population scale impacts.
… (IBM) and consideration of the species’ unique foraging behaviour. This study contributes to the understanding of the factors structuring soft sediment benthic communities, including the use of data from fine-scale hydrodynamic models. It offers a unique comparison of the spatial and temporal …

Seed dispersal effectiveness of samango monkey (Cercopithecus albogularis schwarzi)
… the feeding and movement behaviour of a highly social frugivore, influences seed dispersal effectiveness (SDE) and plant fitness. I achieved this by deconstructing the different components of seed dispersal, the quality of dispersal and the quantity of dispersal and investigated how the …

Sentinel behaviour and urban environments: A corvid’s perspective
… adaptations are an active area of research, social behaviour adaptations and their contribution to the success of urbanized species are underexplored. Sentinel behaviour is a social behaviour that could increase a species' survival of group members. Using a scoping review approach, several …
