“…Our findings clearly show how the avian communities change seasonally in the continental temperate zone: from very rich during the breeding season to less rich and complex during winter. This seems obvious considering the high proportion of breeding migratory species (Tworek 2002(Tworek , 2003Skorka et al 2006). Our findings are aligned with the fact that, for different phenological seasons, different bird species form the base of avian communities (Tworek 2002), reflected by the changes in seasonal dominance of some bird species ( Figure 6A).…”

“…Negative factors that play an important role at the European scale and are also important in the study area include land-use change from meadows and pastures to arable fields, increased use of pesticides and fertilizers, and habitat fragmentation (Geiger et al 2010;Kociolek et al 2011;Tryjanowski et al 2011). However, the local farmlands in Poland support extremely rich bird communities, which contrasts markedly to the farmland habitats in Western Europe (Skorka et al 2006;Tryjanowski et al 2011). There are probably different reasons for this high bird species richness.…”

“…There are probably different reasons for this high bird species richness. First, the study area is a place with extensive agriculture and is located in a complex landscape in a river valley, which attracts high numbers of the common species (Skorka et al 2006) that play an essential role in the conservation of ecosystems (Gaston & Fuller 2008). The indication of real importance of agro-ecosystems for the conservation can be neglected when the studies are focused only on breeding season (Herzon et al 2014).…”

To study the seasonal changes in avian communities, we collected data in an extensively used farmland in Western Poland during [2006][2007][2008][2009][2010][2011][2012][2013]. Generalized additive mixed models were used in order to study the effects of seasonality and protected areas on the overall bird species richness. A similarity percentage analysis was also conducted in order to identify the species that contribute most strongly to dissimilarity among each bird according to the phenological season. Furthermore, the differences in bird communities were investigated applying the decomposition of the species richness in season, trend, and remainder components. Each season showed significant differences in bird species richness (seasonality effect). The effect of the protected areas was slightly positive on the overall species richness for all seasons. However, an overall negative trend was detected for the entire period of eight years. The bird community composition was different among seasons, showing differences in terms of dominant species. Greater differences were found between breeding and wintering seasons, in particular, the spatial pattern of sites with higher bird richness (hotspots) were different between breeding and wintering seasons. Our findings showed a negative trend in bird species richness verified in the Polish farmlands from 2006. This result mirrors the same negative trend already highlighted for Western Europe. The role of protected areas, even if slightly positive, was not enough to mitigate this decline process. Therefore, to effectively protect farmland birds, it is necessary to also consider inter-seasons variation, and for this, we suggest the use of medium-term temporal studies on bird communities' trends.

“…Bell et al 2001;Bonte et al 2002;Mildenstein et al 2005;Skórka et al 2006;Hahn et al 2011). These habitat types are sometimes so distinctive in terms of their resources, vegetation and structure that the behavior and biology of a species may differ substantially depending upon the type (Boudjemadi et al 1999;Potts et al 2001;Allen and Thompson 2010).…”

Resource use in two contrasting habitat types raises different challenges for the conservation of the dryad butterfly Minois dryas

The suitability of any location for a given species is determined by the available resources. However, there are many species that occur in more than one habitat type and their successful conservation may be particularly difficult. The dryad Minois dryas, a locally endangered butterfly, occurs in two contrasting habitats-xerothemic and wet grasslands. We investigated the influence of various habitat characteristics, such as vegetation height, grass cover, proximity of shrubs, plant species composition, Ellenberg indices of trophic and microclimatic conditions, on the microhabitat selection by the species. The nectaring of randomly selected butterflies was observed and habitat characteristics were compared at random points within the meadow and at the butterfly's nectaring and resting places. The butterflies generally preferred to stay close to shrubs and avoided invasive goldenrods. Thermal conditions and the availability of nectar plants were the factors limiting the dryad's use of wet grassland. In xerothermic habitats grass cover affected the distribution of butterflies. Concerning the availability of larval host plants, wet meadows proved potentially more favourable, whereas nectar resources for adults were more abundant in xerothermic grasslands. Based on our findings, conservation strategies for this butterfly must differ in the two habitats. Rotational mowing in xerothermic grasslands and the removal of invasive goldenrods in wet grasslands are the recommended actions. At a larger spatial scale, a habitat mosaic composed of xerothermic and wet grasslands in close proximity would seem to be the most suitable areas for the conservation of the dryad.

“…Several studies from North America and Australia have shown negative responses of riparian breeding bird communities to land management practices (Jansen & Robertson 2001, DeschLnes et al 2003, Scott et al 2003. However, though these wetland habitats may become centres of biodiversity particularly in intensively managed agricultural landscapes (Jansen & Robertson 2001, Skórka et. al 2006, no similar studies have been carried out in Europe.…”
