Removing protected populations to save endangered speciesFranck Courchamp
Ecologie, , , 91405 Orsay, France
Science 302:1532. 2003- Cat dilemma: too protected to escape trophy hunting?Lucille Palazy
Ecologie, Systematique et Evolution, UMR CNRS 8079, Univ Paris Sud, Orsay, France
PLoS ONE 6:e22424. 2011..This suggests an over-exploitation of trophy-hunted felids and the necessity of a better quota system coupled with reconsidered protection methods... - Mammal invaders on islands: impact, control and control impactFranck Courchamp
Université Paris Sud Bat 362 91405 Orsay Cedex, France
Biol Rev Camb Philos Soc 78:347-83. 2003..In addition, long-term monitoring ofthe post-eradication ecosystem is crucial to assess success and prevent reinvasion... - Can bans stimulate wildlife trade?Philippe Rivalan
University Paris Sud, Laboratoire Ecologie, Systematique et Evolution, UMR CNRS 8079, Orsay F 91405, France
Nature 447:529-30. 2007 - Fatal attraction: rare species in the spotlightElena Angulo
Ecologie, Systematique et Evolution, UMR CNRS 8079, Univ Paris Sud, 91405 Orsay Cedex, France
Proc Biol Sci 276:1331-7. 2009..This confirms the AAE as an actual process, which in addition concerns a large part of the population. This has important consequences for the conservation of species that are rare now, or that could become so in the future... - Coupling stable isotopes with bioenergetics to estimate interspecific interactionsStephane Caut
Ecologie, , UMR CNRS 8079, , Orsay, France
Ecol Appl 16:1893-900. 2006..However, when coupled with other approaches, including bioenergetics, mechanistic models, and natural history, stable isotopes can be powerful tools in illuminating interspecific interactions and community dynamics... 
Safety in numbers: extinction arising from predator-driven Allee effectsStephen D Gregory
Ecologie, Systematique et Evolution, UMR CNRS 8079, Univ Paris Sud, Orsay, France
J Anim Ecol 79:511-4. 2010..Although their findings will be sensitive to departures from their experimental protocol, this link between predation and population extinction could have important consequences for many prey species...- Are non-sexual models appropriate for predicting the impact of virus-vectored immunocontraception?Anne Deredec
Ecologie, Systematique et Evolution, Universite Paris Sud XI, Batiment 362, 91405 Orsay Cedex, France
J Theor Biol 250:281-90. 2008..Our analysis also shows that female-specific viruses generally give better results than male-specific ones, and suggests that virus choice should focus more on its sterilizing power rather than transmission efficiency... - Rare species are valued big timeElena Angulo
Ecologie, Systematique et Evolution, UMR CNRS 8079, Universite Paris Sud, Orsay, France
PLoS ONE 4:e5215. 2009..Many hobbies, such as ecotourism or the keeping of exotic pets may cause this effect--known as the anthropogenic Allee effect. However, the entire theory relies on the insofar undemonstrated assumption that people do value rarity... - Limited evidence for the demographic Allee effect from numerous species across taxaStephen D Gregory
Ecologie, Systematique et Evolution, Centre National de la Recherche Scientifique, Unité Mixte de la Recherche CNRS UMR 7089, Universite Paris Sud XI, Batiment 362, Orsay 91405 Cedex, France
Ecology 91:2151-61. 2010..We conclude that there is relatively high potential for demographic Allee effects in these 1198 time series but comparatively few observed cases, perhaps due to the influences of climate and measurement error... - Double Allee effects and extinction in the island foxElena Angulo
Ecologie, Systematique et Evolution, UMR CNRS 8079, University of Paris Sud, Orsay Cedex 91405, France
Conserv Biol 21:1082-91. 2007..Conservationists should also be aware of AEs when planning the release of captive foxes. More generally, our findings highlight the danger of overlooking AEs in the conservation of populations of rare or threatened species... - Invading parasitoids suffer no Allee effect: a manipulative field experimentXavier Fauvergue
Institut National de la Recherche Agronomique INRA, 400 Route des Chappes, 06903 Sophia Antipolis Cedex, France
Ecology 88:2392-403. 2007..This is, to our knowledge, the first experimental test of the Allee effect in an invading parasitoid. It leads us to propose that a number of behavioral and life-history features of many parasitoids could protect them from Allee effects... - Multiple Allee effects and population managementLudek Berec
Department of Theoretical Ecology, Institute of Entomology, Biology Centre ASCR, Branisovska 31, 37005 Ceske Budejovice, Czech Republic
Trends Ecol Evol 22:185-91. 2007..We suggest that more research is needed to assess the prevalence and interactions of multiple Allee effects, as failing to take them into account could have adverse consequences for the management of threatened or exploited populations... - Golden eagles, feral pigs, and insular carnivores: how exotic species turn native predators into preyGary W Roemer
Department of Organismic Biology, Ecology, and Evolution, University of California, Los Angeles, CA 90095, USA
Proc Natl Acad Sci U S A 99:791-6. 2002..The presence of exotic pigs led to major ecosystem shifts by indirectly causing predation to replace competition as the dominant force shaping these island communities... - Achilles' heel of sociality revealed by energetic poverty trap in cursorial huntersGregory S A Rasmussen
