• Perturbation and delayed recovery of the reed invertebrate assemblage in Camargue marshes sprayed with Bacillus thuringiensis israelensis
  de Brigitte Poulin, Gaëtan Lefebvre In Insect Science, 25:4 (2018/08/01), 542-548 En ligne : onlinelibrary.wiley.com[...] Bacillus thuringiensis var. israelensis (Bti) is the most commonly used larvicide to control mosquitoes worldwide. Considered as nontoxic to most organisms, Bti can nevertheless cause trophic perturbations to natural communities by reducing the ... read more
• Résultats du suivi de l’impact potentiel des traitements au Bti sur les invertébrés paludicoles et les hirondelles des fenêtres en Camargue pour la période 2006-2009 (2010)
  de Brigitte Poulin, Gaëtan Lefebvre, E. Duborper, L. Paz Arles : Parc naturel régional de Camargue, 2010, 20 Depuis la découverte de sa toxicité aigüe et sélective envers les Nématocères (sous-ordre des diptères incluant les moustiques et les chironomes) en 1977 par Goldberg & Margalit, Bacillus thuringiensis var. israelensis (Bti) est devenu ... read more
• Reed harvest and summer drawdoum enhance bittern habitat in the Camargue
  de Brigitte Poulin, Gaëtan Lefebvre, Stephanie Allard, Raphael Mathevet In Biological Conservation, 142:3 (MAR 2009), 689-695 The vulnerable Eurasian bittern Botaurus stellaris has recently benefited from conservation actions in several European countries. The Camargue in Mediterranean France holds 8000 ha of reed marshes and 50% of the French ... read more
• Optimal sampling of booming Bitterns Botaurus stellaris
  de Brigitte Poulin, Gaëtan Lefebvre In Ornis Fennica, 80:1 (2003), 11-20 The Great Bittern Botaurus stellaris is a secretive bird that lives in dense reed marshes. Population surveys of this vulnerable species are based on the characteristic vocalization (booms) of males during the breeding season. Probability of detecting ... read more
• Accuracy of bittern location by acoustic triangulation
  de Gaëtan Lefebvre, Brigitte Poulin In Journal of Field Ornithology, 74:3 (SUM 2003), 305-311 Ecological studies and population surveys sometimes require information on the position of individuals. Because many birds are more audible than visible, we tested the potential of acoustic triangulation for locating Great Bitterns (Botaurus stellaris) ... read more
• Quantifying the breeding assemblage of reedbed passerines with mist-net and point-count surveys
  de Brigitte Poulin, Gaëtan Lefebvre, P. Pilard In Journal of Field Ornithology, 71:3 (SUM 2000), 443-454 Data collected in a 40-ha reedbed of southers France were used to compare the efficiency and limitation of mist-net and point-count techniques in estimating the composition and structure of a bird assemblage ... read more
• Integrating bird ecology with socio-economy for a sustainable wetland management
  de Brigitte Poulin, R. Mathevet, Gaëtan Lefebvre In Journal of Ornithology, 147:5, Suppl. 1 (AUG 2006), 80-80 ... read more
• High Stocking Density Controls Phillyrea Angustifolia in Mediterranean Grasslands
  de François Mesléard, Nicole Yavercovski, Gaëtan Lefebvre, Loic Willm, Anne Bonis In Environmental Management, 59:3 (2017/03/01), 455-463 En ligne : link.springer.com[...] Extensive grazing applied in the form of low instantaneous pressure over a long period is a widespread management practice in protected areas. However this kind of stocking ... read more
• Mosquito Traps: An Innovative, Environmentally Friendly Technique to Control Mosquitoes
  de Brigitte Poulin, Gaëtan Lefebvre, Camille Muranyi-Kovacs, Samuel Hilaire In International Journal of Environmental Research and Public Health, 14:3 (2017-03-18), 313 En ligne : www.mdpi.com[...] We tested the use of mosquito traps as an alternative to spraying insecticide in Camargue (France) following the significant impacts observed on the ... read more
• Perturbation and delayed recovery of the reed invertebrate assemblage in Camargue marshes sprayed with Bacillus thuringiensis israelensis
  de Brigitte Poulin, Gaëtan Lefebvre In Insect Science (December 2016) En ligne : onlinelibrary.wiley.com[...] Bacillus thuringiensis var. israelensis (Bti) is the most commonly used larvicide to control mosquitoes worldwide. Considered as non-toxic to most organisms, Bti can nevertheless cause trophic perturbations to natural communities by reducing the abundance ... read more
