Birds are commonly used as an example of the strongly declining farmland biodiversity in Europe. The populations many species have been shown to suffer from intensification management, reduction landscape heterogeneity, and habitat loss fragmentation. These conditions particularly dominate economically well developed countries Western Currently, environment Central-Eastern Europe is generally more extensive than a larger proportion people still live rural areas; thus generating different for...
Harvesting represents a major source of mortality in many deer populations. The extent to which harvesting is selective for specific traits important order understand contemporary evolutionary processes. In addition, since such data are frequently used life-history studies, it know the pattern selectivity as bias. Recently, was demonstrated that different hunting methods were selected weights red ( Cervus elaphus ), but little insight offered into why this occurs. study, we show foreign...
-We captured, banded (n = 4,129), and weighed 809) Mallards (Anas platyrhynchos) during wing molt in western Poland. The condition of remex development was assessed 3,421). We recaptured remeasured 248 birds. rate growth males (calculated by two methods) 6.7 5.5 mm/day (P < 0.02). Males regained flight capability 22-29 days, when remiges had reached 75-83% final length. During the flightless period, females lost 12% body mass. Birds whose period extended to replace only a few damaged quills...
Habitat management should be an important part of the brown hare (Lepus europaeus) conservation, but habitat requirements this species are not fully recognised. The aim our research was to estimate these by analysing effect various agricultural landscape structure features on distribution hares in five areas Germany and Poland. local density assessed spring autumn 2006 using method spotlight-strip counts 9-15 subareas each region. has been described for subarea: share grain, other crops...
The aim of my study was to estimate the effect brown hare Lepus europaeus density, vole abundance and habitat diversity on occurrence hares in diet red fox Vulpes vulpes during breeding season agricultural landscapes. I used average number adult found among food remains scattered around a dens foxes (10–24/year), analysed its temporal variation 1997–2006 an area located western Poland; furthermore, spatial based results from 21 areas various other regions country. Spring index (logarithm...
1. The relationships between the agricultural landscape structure, as a function of arable field size and occurrence permanent cover, abundance insect food partridge chick survival were studied in two areas Poland. One area had small large fields (Czempin) other only (Kutno). Brood was used an index number plant bugs (Heteroptera) resources. 2. cereals increased with cover Czempin, but no relationship found Kutno where there more smaller sizes. 3. average higher than fields. However, insects...
The role of granivorous birds as agents seed dispersal has been little explored and is poorly understood. We assessed the ability three species from a Central European agricultural landscape to disperse seeds dry-fruited plants. hypothesised that Grey Partridge Perdix perdix better disperser than either two buntings—Yellowhammer Emberiza citrinella Reed Bunting schoeniclus—in terms number intact recovered their droppings. droppings contained highest seeds. Surprisingly, however, per 1 g was...
1. The survival of grey partridge chicks was estimated from the brood sizes in several areas Poland, and related to weather conditions, abundance insect food, occurrence weeds, use herbicides. 2. Geometric mean size different years ranged 7-5 11.2, with a 9.3, chick rate 42 71%, 56%. 3. Chick rates increased temperatures decreased increasing numbers rainy days June. 4. plant bugs, but they had no significant effect after removal weather. Numbers bugs temperature

Recently, hunting has represented a major source of mortality in game animals, including red fox, Vulpes vulpes, populations. Data from studies have been used to explain evolutionary changes (body size, dental structure) fox populations; however, knowledge potential sources bias these kinds data is lacking. Moreover, nature and managers as well conservationists recently seeking methods limit European populations, which are increasing. In the present study Polish farmland, we show that three...
Increases in the wild boar Sus scrofa population create many conflicts that must be managed, especially because hunting represents a major cause of mortality this game species. However, effort is not distributed randomly and influenced by factors, including methods. This can important understanding nature pressure for both theoretical (ecological evolutionary) applied reasons (for management purposes, during infectious diseases, example, African swine fever, outbreaks). We analyzed data from...

The photoreflectance spectra for heavily doped p-type GaAs/SI-GaAs structures have been measured at room temperature the energies in vicinity of GaAs band gap. complex function is defined and determined by means a Kramers–Krönig analysis from spectra. modulus gives us critical point energy whereas phase this can be used topographical study homogeneity internal electric field structure.
Abstract The aim of this study was to estimate the effect agricultural landscape structure on predation rate red foxes Vulpes vulpes grey partridges Perdix perdix during breeding season and their spatial relations. number partridge remains found around fox dens (N=165) used as an index in 10 areas. Moreover, distribution both species searching intensity nesting habitat (permanent semi-natural vegetation) by relation were studied using scat, track call counts. (range 0.06–0.46 partridges/den)...
Abstract In dimorphic species, sexual habitat segregation is generally explained by the differences in nutritional needs or a trade‐off between fulfilling food requirements and avoiding predation. However, it remains unclear whether predation risk strong enough to drive use sexes as predicted sensitivity hypothesis. Here we test monomorphic brown hare ( Lepus europaeus ), prediction that abundance of gender more sensitive higher safer habitat. We used data on 1645 individually marked hares...
Brood production rate of Grey Partridges Perdix perdix was studied in three areas Poland the years 1986–90, by comparing number pairs and family coveys after breeding period. In study areas, linear permanent nesting cover mapped measured. these brood declined with increasing spring pair density. A positive effect occurrence on found. An increase population density mostly occurred through occupying parts area avoided earlier, thus presumably less suitable for Partridges. Pairs characterized...
