Spatio-temporal dynamics of arable weed populations
We are mapping selected non-crop species across the fields of 50 arable farms in three counties of the eastern lowlands of the UK over three years. These hierachical data will then be used to explore the factors influencing the population dynamics of the weeds themselves, and also how human socio-economics and birdlife are affected by changes in weed abundance.
Spatially-explicit maps of different density states are generated from censuses of seedlings, mature weeds and autumn stubbles...
 ...for common weed species such as blackgrass (Alopecurus myosuroides). . . |  ... to less abundant species such as wild oats (Fatua avena). |
Statistical analyses
 | Weed abundances are divided into several categories of increasing density. |
 | Transitions between these density categories are modelled using a matrix modelling appraoach, using density state rather than more traditional life history stage. |
