Fabien Verniest, Auteur ; Thomas Galewski, Auteur ; Romain Julliard, Auteur ; Anis Guelmami, Auteur ; Isabelle Le Viol, AuteurIdentifying sites that are both important for biodiversity and likely to be heavily affected by anthropogenic pressures in the future is crucial to settle priorities in the implementation of conservation measures, such as the designation of new [...]Article
Magali Weissgerber, Auteur ; Samuel Roturier, Auteur ; Romain Julliard, Auteur ; Fanny Guillet, AuteurBiodiversity offsetting is usually the last step in the mitigation hierarchy and aims to compensate for impacts of development projects on biodiversity. It is supposed to contribute to the key environmental objective of “no net loss” of biodiver[...]Article

Baillie, AuteurPopulations of migratory songbirds in western Europe show considerable variation in population trends between species and regions. The demographic and environmental causes of these large-scale patterns are poorly understood. Using data from Cons[...]Article
Jean-Pierre Moussus, Auteur ; Frédéric Jiguet, Auteur ; Joanne Clavel, Auteur ; Romain Julliard, AuteurDans Bird Study (56 2009)Capsule Large-scale abundance monitoring programmes can be used to estimate annual phenological shifts. Aims Phenology refers to the timing of any annually repeated biological event. The method developed here aims at measuring phenological varia[...]Article
Vincent Devictor, Auteur ; Romain Julliard, Auteur ; Denis Couvet, Auteur ; Frédéric Jiguet, AuteurRange shifts of many species are now documented as a response to global warming. But whether these observed changes are occurring fast enough remains uncertain and hardly quantifiable. Here, we developed a simple framework to measure change in c[...]Article

Demographic consequences of prey availability and diet of Red-billed Choughs Pyrrhocorax pyrrhocorax
Christian Kerbiriou, Auteur ; Romain Julliard, AuteurCapsule Variation in prey availability appears to influence Chough fledging success and juvenile survival. Aims To determine seasonal and annual variations in Chough prey and how these influence fledging success and juvenile survival. Methods Ch[...]Article
Francois Chiron, Auteur ; Romain Julliard, AuteurControl to limit damage caused by undesirable organisms at the country level is a common management practice but its effects on the target populations are usually unknown. Monitoring consequences of control is however important to design and mea[...]Article

Vincent Devictor, Auteur ; Laurent Godet, Auteur ; Romain Julliard, Auteur ; Denis Couvet, Auteur ; Frédéric Jiguet, AuteurWe studied the role played by the French protected area network on 100 common bird species at the population and community level. The long-term trend of each species was calculated over 15 years (1989-2003). We then used 418 plots monitored by t[...]Article
Isabelle Le Viol, Auteur ; Julien Mocq, Auteur ; Romain Julliard, Auteur ; Christian Kerbiriou, AuteurBiodiversity conservation does predominantly focus on protected natural areas, but has to consider also the usually Human-dominated matrix in which these natural areas are embedded. Here we study highway stormwater retention ponds, which may act[...]Article
Caterina Penone, Auteur ; Nathalie Machon, Auteur ; Romain Julliard, Auteur ; Isabelle Le Viol, AuteurFunctional connectivity is essential to maintaining biodiversity in fragmented landscapes but little attention has been given to structures that can provide it in an urban context. Using both the taxonomic and functional diversity of semi-natura[...]Article
