Czech Bird Data (managers: Reif and Vermouzek)

Abundance of breeding bird species counted two times in eight habitats in 2006-2008 within a large-scale breeding bird monitoring scheme covering the Czech Republic

Relationships between long-term population trends of birds breeding in the Giant Mountains and their predictors.

<p>The trends were estimated for the time period 1984–2011 and are significantly related to (a) mean altitude of breeding occurrence at beginning of the monitoring period (the higher the value, the higher altitude a given species uses for breeding) and (b) migration strategy (the higher the value, the longer migration route a given species takes) as revealed by the linear main effects model (see text for more details on particular variables and the model). The plots show pure effects of the focal variables after controlling for the effects of all other traits.</p

Population Trends of Central European Montane Birds Provide Evidence for Adverse Impacts of Climate Change on High-Altitude Species

<div><p>Climate change is among the most important global threats to biodiversity and mountain areas are supposed to be under especially high pressure. Although recent modelling studies suggest considerable future range contractions of montane species accompanied with increased extinction risk, data allowing to test actual population consequences of the observed climate changes and identifying traits associated to their adverse impacts are very scarce. To fill this knowledge gap, we estimated long-term population trends of montane birds from 1984 to 2011 in a central European mountain range, the Giant Mountains (Krkonoše), where significant warming occurred over this period. We then related the population trends to several species' traits related to the climate change effects. We found that the species breeding in various habitats at higher altitudes had more negative trends than species breeding at lower altitudes. We also found that the species moved upwards as a response to warming climate, and these altitudinal range shifts were associated with more positive population trends at lower altitudes than at higher altitudes. Moreover, long-distance migrants declined more than residents or species migrating for shorter distances. Taken together, these results indicate that the climate change, besides other possible environmental changes, already influences populations of montane birds with particularly adverse impacts on high-altitude species such as water pipit (<i>Anthus spinoletta</i>). It is evident that the alpine species, predicted to undergo serious climatically induced range contractions due to warming climate in the future, already started moving along this trajectory.</p></div

Magnitude and direction of population trends, ecological and life-history traits of 36 passerine species breeding in Europe between 2001 and 2012

Magnitude and direction of population trends (1 = 100%), ecological and life-history traits of 36 passerine species breeding in Europe between 2001 and 2012. Non-breeding niche position varies from 1 (closed forest) to 7 (open country) and non-breeding niche breadth expresses the difference between the values of the two main habitats; non-breeding habitat wetness scores from (1) dry to (3) aquatic habitats. Non-breeding regions: (1) west–central region, (2) west–east region, (3) central–south region, (4) ‘entire’ region. Breeding habitat: forest (F), wetland (W), urban (U) and open habitat (O). PC 1 expresses a gradient from ‘slower strategy’ (K-selected) species to ‘faster strategy’ (r-selected) species. PC 2 depicts a gradient from species allocating most of their energy to just one breeding attempt per season to species spreading their investments across multiple breeding attempts per season

Habitat-specific diversity in Central European birds

Bird species richness was highest in forest and urban habitat types, lower in grassland and wetland, and lowest in cropland. To investigate bird species richness patterns across different habitat types in Czechia, Central Europe. Data from a national breeding bird monitoring scheme in Czechia, based on mapping of positions of individual birds along transects, were used to express the number of species in habitat polygons. Each polygon was represented by one of the eight habitat types (coniferous, mixed and deciduous forest, cropland, grassland and other open habitat types, urban habitat, and wetland) obtained by detailed country-wide vegetation mapping. Species richness of individual polygons was related to polygon habitat type and area by linear mixed effects models, taking the surrounding land cover composition into account. Bird species richness was highest in forest, as predicted, and respective forest habitat types did not differ from each other. Urban habitat hosted a similar number of species as forest. Species richness varied greatly between different open habitat types: cropland was the most species-poor of all the habitat types considered, whereas grassland and other types of open habitats hosted significantly more species, albeit fewer than forests, and did not differ from wetland. Slopes of species-area relationships in respective habitat types largely followed the patterns in species richness. The observed patterns are partly driven by natural habitat characteristics, such as high vertical stratification of forest vegetation facilitating coexistence of a higher number of species. However, biogeography may also play a role, for example, and the relatively short time periods for colonization from Eastern European source areas may underpin lower bird species richness in grasslands. In addition, human interventions may drive the steep slope of the species-area relationship in forest, presumably caused by mosaic harvesting, as well as the shallow slope of this relationship in cropland and wetland, as a result of their intensive exploitation.</p
