Ecological Understanding

Most standard theoretical approaches emphasize the role of deterministic density dependence in creating and maintaining equilibrium dynamics. At the same time, it is widely recognized that ecological processes are inherently stochastic, and that disturbances and variation in the environment and in the fates of individuals prevent many ecological systems from resting at their theoretical equilibrium. A developing body of stochastic ecological theory aims to bridge the gap between the deterministic tools of classical theory and the stochastic, non-equilibrial questions that real systems present to us. This chapter provides an overview of this developing theory, with an emphasis on approaches that confront the complex interplay between deterministic density dependence, and perturbations. Although intuition may suggest that stochasticity and transient phenomena should obscure ecological understanding, they can actually strengthen it when viewed through the appropriate lens, as illustrated in this chapter.

AbstractIt is over 30 years since Paul Buckland first presented a series of arguments concerning beetle (Coleoptera) grain pests: their origin, the timing of their introduction to Britain, and their implications for agricultural production during the Roman occupation. Here we return to the topic in the light of new data from a range of archaeological deposits, including civilian and military sites dating from the earliest period of Roman occupation. Infestation rates and, potentially, grain loss may have been high throughout Roman Britain, though many infestations may have been in equine feed. Beetle grain pests are not recorded in Britain prior to the Roman invasion, and it appears that they were absent, or extremely rare, in the early medieval period and up to the Norman Conquest. This pattern of occurrence is reviewed and it is suggested that ecological theory offers an explanation which is in accord with supposed socio-economic changes and trade. The role of grain pests is considered in the economic modelling of Romano-British agriculture.

The use of home visits has a long and storied history in the United States from different disciplines, such as nursing, prenatal mothers, young families, health promotion, and community corrections. Ecological theory explains how formal actors play a role in the promotion in the health field through home visits, but does not address community corrections home visits. Through the use of 30 semi-structured interviews, this research seeks to expand the understanding of ecological theory by capturing the perceptions of offenders sentenced to home visits conducted by a sheriff’s office. The findings suggest the participants supported the home visits by formal agents and, in general, the home visits created an atmosphere of respect between the participants and sheriff’s office personnel. This study creates the context for future research to understand the role of formal agents in recidivism and evaluate the efficacy of home visits by community corrections agencies.
