“…In open agricultural landscapes, woody habitats are subject to minimal disturbance and are often the closest potential alternative to natural vegetation, making them important source habitats. Many open land organisms depend on woody structures (Duelli and Obrist 2003;Kremen et al 2004;Holzschuh et al 2009;Sanderson et al 2009). Therefore, biodiversity and ecosystem functions (Kremen et al 2004;Klein et al 2007;Farwig et al 2009) in open agricultural landscapes are strongly influenced by woody habitats.…”

Habitat loss and fragmentation are major threats to biodiversity and ecosystem functioning. Effects of these usually intercorrelated processes on biodiversity have rarely been separated at a landscape scale. We studied the independent effects of amount of woody habitat in the landscape and three levels of isolation from the next woody habitat (patch isolation) on trap nesting bees, wasps, and their enemies at 30 farmland sites in the Swiss plateau. Species richness of wasps was negatively affected by patch isolation and positively affected by the amount of woody habitat in the landscape. In contrast, species richness of bees was neither influenced by patch isolation nor by landscape composition. Isolation from woody habitats reduced species richness and abundance of natural enemies more strongly than of their hosts, so that parasitism rate was lowered by half in isolated sites compared to forest edges. Thus, population regulation of the hosts may be weakened by habitat fragmentation. We conclude that habitat amount at the landscape scale and local patch connectivity are simultaneously important for biodiversity conservation.

“…For example, the White Stork Ciconia ciconia prefers a high value of NDVI in June but only on meadows (Kosicki 2010), while the Yellowhammer Emberiza citrinella (Whittingham et al 2005) and the Great Grey Shrike Lanius excubitor (Kuczyn´ski et al 2010) prefer mixed open habitats always with a high rate of NDVI (Bacaro et al 2011). Furthermore, farmland ''focal'' bird species as well as total species richness also depend on the high value of NDVI (Sanderson et al 2009;Bacaro et al 2011;Kosicki and Chylarecki 2012). So, our study confirms the general pattern that a higher spectral index, in our case NDVI, corresponds to the higher probability of species occurrence even with respect to birds linked only to largescale monoculture areas (Palmer et al 2002).…”

“…It is the only species of Phasianidae that undertakes long-distance migrations, spending the winter in the Sahel zone. Migratory habits and Sahel wintering grounds are factors making the species more vulnerable than others to population declines (Sanderson et al 2009). A large decline of the European Quail's population was observed in , followed by a shallow decline hence after, coupled with some increase noted in northern parts of its range (BirdLife International 2004;Sanderson et al 2009).…”

Over the last four decades, the majority of European farmland birds have shown marked population declines attributed to the intensification of agriculture. The Common Quail is a widespread farmland breeder across most of Europe. Its populations have shown marked decline, particularly pronounced at the end of the previous century. Ongoing agriculture intensification may be the factor responsible for the observed declines; however, links between species occurrence and farming intensification have not been addressed so far. We analyzed factors affecting the occurrence of the Quail in Poland using data from 722 1 · 1-km study plots and a set of 22 environmental variables, including proxies for agriculture intensification. Predictors were aggregated using PCAs and related to species presence/ absence data using GAMs. The best-supported model of the species' occurrence included eight variables and was clearly better (AIC weight = 0.54) than other models. Quails preferred open fields, showing high photosynthetic activity in March or June, with rather low precipitation and often at relatively high altitudes (up to 900 m a.s.l.). Importantly, quails were more frequent on plots located in regions with rather high inorganic fertilizer input, and showed no avoidance of areas with a high level of agriculture mechanization. We postulate that singing male quails are attracted to areas with medium or high intensity of agriculture but it may represent a maladaptive habitat choice enhanced by changing agriculture practices and peculiarities of the quail's breeding strategy. Given the results, the quail cannot be classified as a good indicator of extensive traditional agriculture.

“…The population trend declining in many European countries (BIRDLIFE INTERNATIONAL, 2016) owing to the intensive agricultural practices, the use of pesticides and heightened mortality during migration (SANDERSON et al, 2009, KOSICKI et al, 2014. Additionally, Common Quails are subjected to significant hunting pressure during the autumn migration period, especially in the Mediterranean countries (TUCKER & HEATH, 1994;GALLEGO et al, 1997;PUIGCERVER et al, 1998).…”

Common Quail (Coturnix coturnix) mainly breed in cereal crops and fallow grasslands, where they are threatened by harvesting/mowing. The aim of this research was to assess the impact of unmown refuge areas to the density and movements of Common Quails in the Moson Project, Northwest Hungary. The selected 80 ha study area was first visited shortly before mowing, while the second survey was carried out two weeks after mowing operation ended. Calling males of Common Quail were documented and their vocalizations were recoded. During the first survey (before mowing), a total of 18 Common Quails were recorded, while the second survey (after mowing) resulted in a lower number (14) of birds detected. In terms of density, the initially determined 2.25 calling males/10 ha decreased to 1.75 males/10 ha. For individual recognition bioacoustic methods were used. A total of six time and frequency-based variables were measured and were subjected to discriminant function analysis (DFA). A total of 9 males were re-identified with high probability, proving that the 15-20 m wide unmown refuge-srips can still provide optimal habitats for quails. A fürj (Coturnix coturnix) a mezei élőhelyek jellegzetes fészkelő madara. Költ a különböző mezőgazdasági kultúrákban, ugar jellegű élőhelyeken, ahol a betakarítás illetve kaszálás nagy veszélyt jelent a fészkelési időszakban. Jelen kutatás a kaszálatlanul hagyott búvósávok szerepét vizsgálja a fürjek denzitása valamint területhűsége vonatkozásában egy északnyugat-magyarországi élőhelyen (MOSON Project). A fürjek felmérésére a vizsgálatokhoz kiválasztott mintegy 80 hektár nagyságú területen először a kaszálás időpontja előtt, majd ezt követően a kaszálás befejezése után két héttel került sor. Az éneklő kakasok számának feljegyzése mellett hangfelvételeket is készítettünk. Az első felmérés során összesen 18, majd a kaszálás után 14 hím egyedet detektáltunk, így a denzitás 2.25 éneklő kakas/10 ha-ról 1.75 éneklő kakas/10 ha értékre csökkent a kaszálást követően. Az éneklő hím egyedek elkülönítése bioakusztikai módszerekkel történt, amihez a fürj hangját jól reprezentáló hat hangfizikai változó mérését végeztük el a rögzített hangmintákon. A hangfizikai változók adatmátrixát diszkriminancia-analízis (DFA) segítségével elemeztük. Összesen 9 fürj kakas újraazonosítása sikerült nagy biztonsággal, amely alapján azt a következtetést vonhatjuk le, hogy a kaszálatlanul hagyott 15-20 m széles búvósávok megfelelő élőhelyet tudnak biztosítani a fürj számára.
