Seasonality is an important feature of essentially all natural systems but the consequences of seasonality have been vastly underappreciated. Early work emphasized the role of seasonality in driving cyclic population dynamics, but the consequences of seasonality for ecological processes are far broader. Yet, seasonality is often not explicitly included in either empirical or theoretical studies. Many aspects of ecological dynamics can only be understood when seasonality is included, ranging from the oscillations in the incidence of childhood diseases to the coexistence of species. Through several case studies, we outline what is now known about seasonality in an ecological context and set the stage for future efforts. We discuss approaches for incorporating seasonality in mathematical models, including Floquet theory. We argue, however, that these tools are still limited in scope and more approaches need to be developed.

Seasonality is an important feature of essentially all natural systems but the consequences of seasonality have been vastly underappreciated. Early work emphasized the role of seasonality in driving cyclic population dynamics, but the consequences of seasonality for ecological processes are far broader. In ecological systems, seasonality may include variations in temperature, precipitation, or other processes. Seasonality is typically not explicitly included in either empirical or theoretical studies. However, many aspects of ecological dynamics can only be understood when seasonality is included, ranging from the oscillations in the incidence of childhood diseases to the coexistence of species. Further, studies of phenology and global climate change only make sense in the context of seasonal dynamics. Our goal is to outline what is now known about seasonality and to set the stage for future efforts. We review the effects of seasonality on ecological systems in both laboratory and field settings. We then discuss approaches for incorporating seasonality in mathematical models, including Floquet theory. We argue, however, that these tools are still limited in scope and more approaches need to be developed. We demonstrate the range of impacts of seasonality on ecological systems and show the necessity of incorporating seasonality to understand ecological dynamics.

Host Parasite

The study of parasite population dynamics has been one of the major developments in ecology over the last 15 years (Kennedy, 1975). The seminal articles of Crofton (1971) and Anderson & May (1978, 1979; May & Anderson, 1978, 1979) began this process by illustrating the potential role of parasites in regulating or destabilizing the dynamics of wildlife host populations. Since then, a variety of empirical and theoretical studies (reviewed by Grenfell & Dobson, 1995) have explored the role of parasites in natural populations. In parallel with these population dynamical developments, a growing interest in the evolutionary ecology of parasites has also led to a large literature, examining the evolutionary impact of parasites and the importance of host-parasite coevolution (Hamilton, 1982; May & Anderson, 1990; Lively & Apanius, 1995; Read et al. 1995; Herre, this volume).

The Impact

This paper explores the role of mathematical models in archaeology and history. Variants of a particular model — an entropy-maximizing spatial interaction model which also functions as a location model — are presented through two case studies. The first is an example from Archaeology which throws light on settlement sizes in the 9th and 8th century BC Greece; the second is from History and explores the evolution of the United States' urban system from 1790–1870 with particular reference to the impact of railways. The approach is essentially interdisciplinary and uses concepts from Geography, Economics, Physics and Ecology.

Local Practices

The aim of this track was to question the divide between the nature of knowledge understood as experiential in indigenous contexts and science as an objective transferable knowledge. However, these can co-exist and inform design practices within transforming social contexts. The track aimed to challenge the hegemony of dominant knowledge systems, and demonstrate co-existence. The track also hoped to make a case for other systems of knowledges and ways of knowing through examples from native communities. The track was particularly interested in, first, how innovators use indigenous and cultural systems and frameworks to manage or promote innovation and second, the role of local knowledge and culture in transforming innovation as well as the form of local practices inspired innovation. The contributions also aspired to challenge through examples, case studies, theoretical frameworks and methodologies the hegemony of dominant knowledge systems, the divides of ‘academic’ vs ‘non-academic’ and ‘traditional’ vs ‘non-traditional’.
