Animal Social Network Structures Across the Fast-Slow Continuum

|
By Ross Walker, Andy White, Xander O'Neill
| Wiley Online Library Verified
1 Introduction Life history strategies are defined by trade-offs between survival, development and behaviour, which are in turn subject to constraints imposed by resource availability, environmental conditions and allometry (Stearns 1998; Healy et al. 2019). A well-known trade-off that shapes life history strategies is the fast-slow continuum, describing the relative allocation in lifespan and reproduction, termed speed of life (Silk and Hodgson 2021; Healy et al. 2019).

The Role of Pace of Life in Animal Social Networks

|
By Ross Walker, Andy White, Xander O'Neill, Nina H Fefferman
| BioRxiv
Abstract Pace of life history is a key axis of variation in life history strategies that captures the evolutionary trade-off between investing in lifespan versus reproduction. It has been suggested that social behaviour, and therefore network structure, may vary with pace of life, but formal theory remains scarce. We develop a novel mathematical model to examine how differences in demographic turnover may constrain emergent social network structures in natural populations.

The evolution of parasite virulence under targeted culling and harvesting in wildlife and livestock

|
By Xander O'Neill, Andy White, Mike Boots, Heriot-Watt Edinburgh
| Wiley Online Library Verified
1 INTRODUCTION Experimental, field and in particular theoretical studies exploring the evolution of parasite virulence and transmission are well-developed (see Cressler et al., 2016 for a review). Theoretical studies have generally assumed that the evolution of parasite virulence (defined in this literature as an increased death rate due to infection) is dependent on a trade-off with other host and parasite characteristics (Alizon et al., 2009; Anderson & May, 1982; Ewald, 1983).

The impact of an African swine fever outbreak on endemic tuberculosis in wild boar populations: A model analysis

|
By Xander O'Neill, Andrew White, Francisco Ruiz-Fons, Christian Gortázar
| Wiley Online Library Verified
Abstract A mathematical model is developed and analysed to examine the impacts of African swine fever (ASF) introduction into a wild boar population that supports endemic animal tuberculosis (TB). TB is a widespread infectious disease caused by the Mycobacterium tuberculosis bacteria belonging to the Mycobacterium tuberculosis complex (MTC) that can persist in reservoir wildlife hosts.
