Spatio-temporal variations in faecal nitrogen (FN) and acid detergent fibre (ADF) contents. FN and ADF concentrations (mean ± 95% CI, as % of dry weight) were compared between the north and south ranges used by marked impalas in relation to seasons in years of higher (2002) and lower (2003) population density. A three-way anova revealed significant main effects of year, season and range (P < 0.001; see text for details).
