An ecosystem engineer is a species that indirectly changes the availability of resources for other organisms via physical modification of the habitat. A good example of such species is Ardea cinerea L. – a big waterbird that forms colonies up to a few hundreds of nests during the breeding season. The colonies modify the habitat in the close vicinit...

The aim of the study that was carried out during 1999 and 2000 was to find out whether the soil seed bank might play a significant role in the maintenance of valuable components of xerothermic grassland. Plant community searched is situated on the calcareous hill called The White Mountain (Central Roztocze region, SE Poland). This area is protected...
Article
Full-text available
The grey heron ( Ardea cinerea ) is a good example of an engineering species that forms nesting colonies (called heronries) composed of up to a few hundred nests during the breeding season. It exerts strong pressure on surrounding vegetation, mainly because of the heavy input of organic matter and high eutrophication. The birds also alter light con...

The aim of our study was to evaluate the relationship between dispersed seed pool and the diet structure of the Rook Corvus frugilegus in urban and agricultural habitat types in two eographical regions of Central and Southeastern Europe. We studied the content of regurgitation pellets (N=188) collected in urban and agricultural habitats of Poland a...
Article
Full-text available
The role of granivorous birds as agents of seed dispersal has been little explored and is poorly understood. We assessed the ability of three species of birds from a Central European agricultural landscape to disperse seeds of dry-fruited plants. We hypothesised that Grey Partridge Perdix perdix is a better seed disperser than either of two species...
Article
Full-text available
Capsule Composition of Yellowhammer diet differed significantly between two major habitat categories: semi-natural (fallow lands, abandoned grassland and road verges) and agricultural habitats (managed fields, stubble fields and manure heaps). Semi-natural habitats and winter stubble fields were important sources of non-cereal plant food and plant...
Article
The white stork can affect plant population and community dynamics and structure in an agricultural landscape. It is a vector transporting large numbers of seeds along with nest material, and it is an ecosystem engineer which builds nests that function as specific habitats for plants. The following questions were asked: (i) What is the structure of...
Article
Full-text available
Seed dispersal seems to be extremely important in agrocoenoses where suitable habitats (patches) are surrounded by an unfavourable environment (matrix). The role of the rook Corvus frugilegus, an omnivorous bird, in seed dispersal was studied in the agricultural landscape of Eastern Poland. We analyzed 739 pellets produced by regurgitation, which w...
Article
We investigated whether the winter diet of a typical seed‐eating bird is hard‐wired in the context of evolutionary hypothesis for granivory. We examined the diet composition of ‘a small‐billed form’ of the reed bunting Emberiza schoeniclus wintering in a sewage farm in south‐western Poland (Central Europe), where unfrozen wastewater provides variou...

Article
Full-text available
The role of frugivorous birds in dispersal of the seeds of fleshy-fruited plants is well understood, but other groups of birds like granivores and omnivores can also act as vectors, especially in the process of non-standard dispersal. In this study we examined the role of two widely distributed birds (the Eurasian Blackbird, Turdus merula, and the...
Article
Full-text available
The endozoochorous dispersal of weed seeds, mediated by birds and without any adaptation to frugivory, has been studied very rarely. We studied the endozoochorous dispersal of viable seeds by the grey partridge Perdix perdix in agricultural landscape. We assessed the content of intact seeds in 609 grey partridge droppings coming from 21 sampling si...
Article
Full-text available
The aim of the study was to broaden the knowledge about the role played by the Magpie (Pica pica L.) in the secondary dispersal of seeds with help of nest material, which takes place in the agricultural landscape with the distinct dominance of arable fields. We also tried to assess which plant life-history traits can be helpful in the dispersal med...
Article

The study aimed to evaluate the role of the Rook Corvus frugilegus in the long-distance seed dispersal in agricultural landscape. According to the literature, Rooks feed in the distance 0.3-1 km from the breeding colonies and 10-40 km from winter communal roosts, and these can be also the potential seed dispersal distances. We concentrated on the d...

We want to assess the soil seed bank reserves on non-recultivated coal mine spoil heaps and examine plant-soil and plant-microbial interactions that may influence a process of germination and establishment of new individuals to the plant cover. This knowledge may help to stimulate the activation of seed resurces in hostile habitats and therefore enhance the rate of their spontaneous revegetation.
