Description:
A significant component of breeding habitat of the grey partridge Perdix perdix in Europe includes field boundaries with idle sites and grassy strips, loss of which is considered as one of the reasons for the decline of grey partridge populations. We associate enduring high densities of wild grey partridges in Prague, the Czech Republic, with the existence of unmanaged wasteland, herbaceous patches spread out between urbanized areas of the capital and its surrounding agricultural landscape. The study combines density estimations, home range analysis, weed seed sampling and plant composition analysis, all with the aim of explaining factors influencing partridges' habitat preference. Patch size, availability of patches within the surrounding landscape and mean height of plant cover were the most important factors influencing the numbers of breeding pairs among patches. Numbers of weed seeds collected on the soil surface seems to be of greater importance than specific plant composition. Although patches supported high densities (tens of pairs km^-^2), the neighboring agricultural landscape supported low densities (<10 pairs km^-^2) with an influence of the distance to the nearest patch. April to June home range size varied around 2.9 ha and tended to be smaller for pairs with higher availability of patch habitat. A sufficient availability of temporary patches in the study area enabled a persistence of grey partridge populations without any support through hand-reared birds or systematic predator control. A surplus of offspring may potentially saturate the less attractive surrounding landscape but only to a reduced extent limited by its carrying capacity. .

Ecologists are aware of the importance of natural dynamics in ecosystems Historically, the focus has been on the development in succession of equilibrium communities, which has generated an understanding of the composition and functioning of ecosystems. Recently, many have focused on the processes of disturbances and the evolutionary significance of such events. This shifted emphasis has inspired studies in diverse systems. The phrase "patch dynamics" (Thompson, 1978) describes their common focus.
The Ecology of Natural Disturbance and Patch Dynamics brings together the findings and ideas of those studying varied systems, presenting a synthesis of diverse individual contributions..
