Paintings predict the distribution of species, or the challenge of selecting environmental predictors and evaluation statistics
TL;DR: The findings confirm the crucial importance of variable selection and the inability of current evaluation metrics to assess the biological significance of distribution models and recommend that researchers carefully select variables according to the species’ ecology and evaluate models only according to their capacity to be transfered in distant areas.

Confronting expert-based and modelled distributions for species with uncertain conservation status: A case study from the corncrake (Crex crex)
TL;DR: In this article, the authors used a method of species distribution modeling (MAXENT) to predict the corncrake range and confronted it to the expert-based map, finding a rather similar distribution with the IUCN estimated range, although less widespread.

Hedgerows diminish the value of meadows for grassland birds: Potential conflicts for agri-environment schemes
Aurélien G. Besnard,Jean Secondi +1 more
TL;DR: In this paper, the authors measured grassland passerine abundance in 99 sampling plots distributed in hay meadow habitat and found that grassland abundance and species richness increased with grassland area.

Vegetation maps based on remote sensing are informative predictors of habitat selection of grassland birds across a wetness gradient
Aurélien G. Besnard,Aurélie Davranche,Sébastien Maugenest,Jan-Bernard Bouzillé,Alain Vian,Jean Secondi +5 more
TL;DR: In this article, the authors used SPOT 5 imagery and phytosociological data to map grassland vegetation in a flood-plain using two methods: continuous Ellenberg index of moisture and identified5 vegetation classes distributed across the wetness gradient.

Evaluating interspecific niche overlaps in environmental and geographic spaces to assess the value of umbrella species
TL;DR: This study highlights the potential of using niche overlap in the environmental and geographic space between the main ground-nesting species of the bird community in these grasslands, including the corncrake and four passerines, and reveals the importance of analysing the sensitivity of outputs when changing thresholds and overlap criteria.
