Journal ArticleDOI
Rarity value and species extinction: the anthropogenic Allee effect.
Franck Courchamp,Elena Angulo,Philippe Rivalan,Richard J. Hall,Laetitia Signoret,Leight Bull,Yves Meinard +6 more
TL;DR: It is argued that the human predisposition to place exaggerated value on rarity fuels disproportionate exploitation of rare species, rendering them even rarer and thus more desirable, ultimately leading them into an extinction vortex.
Journal ArticleDOI
Invasion in a heterogeneous world: resistance, coexistence or hostile takeover?
Brett A. Melbourne,Howard V. Cornell,Kendi F. Davies,Christopher J. Dugaw,Sarah C. Elmendorf,Amy L. Freestone,Richard J. Hall,Susan Harrison,Alan Hastings,Matthew D. Holland,Marcel Holyoak,John G. Lambrinos,Kara A. Moore,Hiroyuki Yokomizo +13 more
TL;DR: An environmental heterogeneity hypothesis of invasions is proposed, whereby heterogeneity both increases invasion success and reduces the impact to native species in the community, because it promotes invasion and coexistence mechanisms that are not possible in homogeneous environments.
Journal ArticleDOI
Wildlife health and supplemental feeding: A review and management recommendations
TL;DR: Adopting feeding practices that validate the nutritional appropriateness of wildlife feed for the target species, make food available at lower densities for short periods at unpredictable times and places to prevent aggregation, and avoid feeding during times of migration, pulses of new recruits, and epidemics are recommended.
Journal ArticleDOI
Can bans stimulate wildlife trade
Philippe Rivalan,Virginie Delmas,Elena Angulo,Leigh S. Bull,Richard J. Hall,Franck Courchamp,Alison M. Rosser,Nigel Leader-Williams +7 more
TL;DR: Proactive management of trade in endangered wildlife makes more sense than last-minute bans that can themselves increase trading activity, argue Philippe Rivalan and his co-authors.
Journal ArticleDOI
Endangering the endangered: The effects of perceived rarity on species exploitation
TL;DR: In this article, a series of illustrative case studies of how perceived rarity affects consumer behavior and hunting pressure are presented, and a model is used to explore the scenario of most conservation concern (where rarity itself fuels increased exploitation).
