Summary Local changes in land use can influence patterns of habitat selection by farmland birds, thus biasing predictions of population responses to land use changes based on wildlife-habitat or niche modelling. This study, based in arable farmland in south-central Spain, determined whether habitat selection (use of agricultural habitats and the distance to roads, tracks and buildings) by Great Bustards Otis tarda varied between two nearby areas with differing land uses. The western sector has… 

Responses of Great Bustard (Otis tarda) subpopulations to land-use changes in southwestern Iberia

Land-use change is the single most important cause of global biodiversity loss. Over millennia, European grassland birds concentrated in low-intensity agro-steppe habitats that are now experiencing

Using dietary analysis and habitat selection to inform conservation management of reintroduced Great Bustards Otis tarda in an agricultural landscape

Great Bustards can adapt to an intensive agricultural setting, but require unrestricted access to adjacent grasslands, and would be best served with small-scale habitat mosaics.

Functional habitat suitability and urban encroachment explain temporal and spatial variations in abundance of a declining farmland bird, the Little Bustard Tetrax tetrax

. Species response to land use can be examined under a functional perspective, where habitats are described according to species´ resource dependencies. Distribution or abundance models based on

Impact of land cover and landfills on the breeding effect and nest occupancy of the white stork in Poland

The results suggest that the use of landfills is not currently essential in the Central-Eastern European population of the white stork, does not affect breeding effect, and may be more frequent in non-breeders.

Contrasting trait assembly patterns in plant and bird communities along environmental and human‐induced land‐use gradients

A potential homogenization of biological communities, as well as low functional diversity and redundancy levels of bird assemblages in the authors' human-dominated study region are suggested, which might potentially compromise the maintenance of key ecological processes under future environmental changes.

Are Species Coexistence Areas a Good Option for Conservation Management? Applications from Fine Scale Modelling in Two Steppe Birds

It is concluded that differences in species' habitat preferences can hinder the efficiency of protected areas with multi-species conservation purposes, highlighting the importance of taking into account the role of biotic interactions when designing conservation measurements.

Habitat Suitability Modeling of Great Bustard, Otis tarda, using ENFA and GIS

The model validation and the map classification of habitat suitability to desirable and undesirable classes indicated that Otis tarda tends to live in marginal habitats, and according to the suitability map, only 6.5% of the study area consists of desirable habitat.

Reduced Dependence of Crested Ibis on Winter-Flooded Rice Fields: Implications for Their Conservation

It is recommended that efforts should be made to protect the existing winter-flooded rice fields and to restore the functionality of natural and semi-natural wetlands, to encourage both in-situ conservation and the re-introduction of the Crested Ibis.

Optimising the attractiveness of winter oilseed rape fields as foraging habitat for the West Pannonian Great Bustard Otis tarda population during winter

Summary Winter oilseed rape represents an important food source for Great Bustards. Great Bustard surveys during four consecutive winters (2005/2006–2008/2009) were used to identify characteristics



Habitat preferences of great bustard Otis tarda flocks in the arable steppes of central Spain: are potentially suitable areas unoccupied?

Summary 1. Great bustards Otis tarda are globally endangered and 50% of the world population now occurs in agro-steppe habitats in Spain. An understanding of the relationship between land use and the

Effects of land abandonment and changing habitat structure on avian assemblages in upland pastures of Bulgaria.

The results showed that habitat complexity, management and landscape position influenced bird community structure and species occurrence within the upland pastures, and bird species with a preference for grazed rather than abandoned pastures had higher conservation status and most were associated with shrub cover.

Modelling the effects of irrigation schemes on the distribution of steppe birds in Mediterranean farmland

Research conducted in several Mediterranean areas indicates that most populations of steppe birds are currently experiencing population declines associated with intensification of traditional

Large-scale habitat selection by agricultural steppe birds in Spain: identifying species–habitat responses using generalized additive models

1. Predictive models of species' distributions are used increasingly in ecological studies investigating features as varied as biodiversity, habitat selection and interspecific competition. In a

Changes in the abundance of farmland birds in relation to the timing of agricultural intensification in England and Wales

1. Over the past three decades changes in agricultural management have resulted in increased crop and grass production. This intensification has been accompanied by population declines among farmland

The results suggest that recent trends in agriculture have had deleterious and measurable effects on bird populations on a continental scale and predict that the introduction of EU agricultural policies into former communist countries hoping to accede to the EU in the near future will result in significant declines in the important bird populations there.

Effects of hunting on the behaviour and spatial distribution of farmland birds: importance of hunting‐free refuges in agricultural areas

Hunting is one of the human activities that directly affect wildlife and has received increasing attention given its socioeconomic dimensions. Most studies have been conducted on coastal and wetland

Farmland biodiversity: is habitat heterogeneity the key?

Should conservation strategies consider spatial generality? Farmland birds show regional not national patterns of habitat association.

It is shown that predictors associated with agri-environment scheme (AES) options had similar effects for 11 bird species on sites with differing farming practice or which differed in the density at which the species was found, suggesting that AES options targeted at a regional scale are more likely to yield beneficial results for farmland birds than options applied uniformly in national schemes.
