| Abstract |
Animals simultaneously navigate spatial and social environments, and their decision-making with respect to those environments constitutes their spatial (e.g. habitat selection) and social (e.g. conspecific associations) phenotypes. The spatial–social interface is a recently introduced conceptual framework linking these components of spatial and social ecology. The spatial–social interface is inherently scale-dependent, yet it has not been integrated with the rich body of literature on ecological scale. Here, we develop a conceptual connection between the spatial–social interface and ecological scale. We propose three key innovations that incrementally build upon each other. First, the use–availability framework that underpins a large body of literature in behavioural ecology can be used in analogy to the phenotype–environment nomenclature and is transferable across the spatial and social realms. Second, both spatial and social phenotypes are hierarchical, with nested components that are linked via constraints—from the top down—or emergent properties—from the bottom up. Finally, in both the spatial and social realms, the definitions of environment and phenotype depend on the focal scale of inquiry. These conceptual innovations cast our understanding of the relationships between social and spatial dimensions of animal ecology in a new light, allowing a more holistic understanding and clearer hypothesis development for animal behaviour. This article is part of the theme issue ‘The spatial–social interface: a theoretical and empirical integration’. |
