Predation on Northern Lapwing Vanellus vanellus nests: the effect of population density and spatial distribution of nests.

Popis výsledku v původním jazyce

Vanellus vanellus, nesting success, predation risk, Mayfield method, aggregability, nest pattern, density dependence, protective umbrella hypothesis The effects of population density, nest pattern, size of nest aggregations and position of nests within aggregations on predation rates were analysed in two Lapwing Vanellus vanellus populations in agricultural landscape in South Bohemia, Czech Republic, 1988-1998. Two sites (Arable Land and Meadow) differed in breeding densities but their nest patterns were similarly clumped. While population density negatively correlated with nest predation rate at both sites, the nest pattern demonstrated only a weak effect. Nest predation was not influenced by distance to the nearest neighbouring nest while it was significantly affected by aggregation size in Meadow but not in Arable Land. Decreasing predation from edge to centre of large aggregations supports Lack´s protective umbrella hypothesis. However, large aggregations in Arable Land experienced
