The last century has seen a steep decline in biodiversity, and anthropization is considered one of the major drivers of this decline. Anthropogenic disturbances, due to human presence and/or activities, may be perceived as chronic stressors by wildlife and potentially lead to deleterious effects on traits related to fitness. The main objective of t...

Agricultural intensification is one of the main threats to biodiversity. Farmland bird specialists such as Montagu's harrier, Circus pygargus, are particularly at risk and declining. Conventional farming (CF) production systems usually involve landscape homogenisation, mechanisation, and the use of synthetic pesticides that may have direct and indi...

Palearctic migrants wintering in Africa commonly use several sites throughout the winter, a strategy known as 'itinerancy'. In this way, migrants track spatiotemporal variation in resources. Despite the importance of this strategy for migratory landbirds, we still lack detailed understanding of how variation in environmental conditions affects site...

La distribution des individus au sein de l'habitat peut dépendre de leur personnalité. Les activités et infrastructures humaines sont des éléments importants du paysage qui peuvent impacter le processus de sélection des habitats. Cependant, en fonction de leur personnalité, les individus peuvent répondre différemment à ces éléments non naturels. Da...

Het kennissysteem voor Agrarisch Natuurbeheer, Beheer-op-Maat (BoM), is in 2019 op een aantal aspecten aangepast aan de wensen van de gebruikers (beheercollectieven). De kaartlagen die aan de basis staan van het kennissysteem – de openheid van het landschap, de bodemvochtigheid, de aanwezigheid van verstorende bronnen en de zwaarte van het gewas – ...

Migratory species are subject to environmental variability occurring on breeding and wintering grounds. Estimating the relative contribution of environmental factors experienced sequentially during breeding and wintering, and their potential interaction, to the variation of survival is crucial to predict population viability of migratory species. H...

The Montagu’s harrier (Circus pygargus) is a semi-colonial raptor species widely but patchily distributed across the Palearctic region with recorded cases of philopatry and presence of extra-pair copulation. In order to assess Montagu’s harrier spatial genetic structure and contemporary gene flow, we developed 16 new microsatellite markers using 45...

On the basis of long-term (2001–2017) and extensive data (> 1700 breeding attempts), we assess factors influencing breeding parameters in Montagu’s Harrier (Circus pygargus), a medium-sized ground-nesting semi-colonial raptor breeding in cereal fields, in a study area in its core distribution range (Extremadura, Spain). We evaluated annual and long...

Although a key demographic trait determining the spatial dynamics of wild populations, dispersal is notoriously difficult to estimate in the field. Indeed, dispersal distances obtained from the monitoring of marked individuals typically lead to biased estimations of dispersal kernels as a consequence of i) restricted spatial scale of the study area...
