The ecology of the aquatic snails that serve as obligatory intermediate hosts of human schistosomiasis is driven by climatic and hydrological factors which result in specific spatial patterns of occurrence and abundance. These patterns in turn affect, jointly with other determinants, the geography of the disease and the timing of transmission windows, with direct implications for the success of control and elimination programmes in the endemic countries. We address the spatial distribution of the intermediate hosts and their seasonal population dynamics within a predictive ecohydrological framework developed at the national scale for Burkina Faso, West Africa. The approach blends river network-wide information on hydrological ephemerality which conditions snail habitat suitability together with ensembles of discrete time ecological models forced by remotely sensed estimates of temperature and precipitation. The models were validated against up to four years of monthly snail abundance data. Simulations of model ensembles accounting for the uncertainty in remotely sensed products adequately reproduce observed snail demographic fluctuations observed in the field across habitat types, and produce national scale predictions by accounting for spatial patterns of hydrological conditions in the country. Geospatial estimates of seasonal snail abundance underpin large-scale, spatially explicit predictions of schistosomiasis incidence. This work can therefore contribute to the development of disease control and elimination programmes.

There is a long history of interest in the study of extinct populations, sometimes called “prehistoric demography” or “archaeological demography.” Most studies have focused on regional population size and trends through time and their explanation. Analyses of a single population at one community are rare.This paper discusses one effort at assessing the dynamics of population at one prehistoric community, the Grasshopper Pueblo, located in east-central Arizona. A long range program of archaeological research is being conducted at the site by the University of Arizona through the Archaeological Field School. This program is sponsored jointly by the Department of Anthropology and the Arizona State Museum and has been supported by the National Science Foundation since 1965.The Grasshopper Ruin, a fourteenth century pueblo, is an example of what some have called “Late Mogollon” or “Prehistoric Western Pueblo” culture. It consists of several main room clusters separated by a presently intermittent stream and surrounded by smaller groupings of rooms. There are approximately 500 rooms at the site. Space does not permit a discussion of the range of problems that we are attempting to solve in our research nor the sampling design. But one aspect of our work, the “Cornering-Growth Project,” has provided us with the relative construction sequences for all the rooms at the community. These data provide a basis for a study of population dynamics.
