此物種詳細資訊 Falkland Islands (Malvinas) (sub-Antarctic) 狀態: 外來 入侵: 出現紀錄: ??? 來源: Douse, A., pers.comm., 2004 in Varnham, 2006 到達日期: 1830s but possibly earlier 簡介: 故意引入 此地點的物種說明: Felis catus, domestic cats were deliberate introduction. Feral cats are found mainly around coasts and near settlements. They are present on most but not all inhabited offshore islands. Found in 73, 10km squares. Feral cats are unlikely to expand their range & distribution. 此地點的管理資訊: There has been some local action to reduce or eliminate cats. The possibility of selective eradication at some localities needs to be considered. It is recommended to reduce cat population in or near sensitive sites. 影響: 威脅瀕危物種: Felis catus may have lead to much reduced populations of some vulnerable species. Breeding of the Tussock bird (Cinclodes antarcticus antarcticus) and the 'Vulnerable (VU)' Cobb's wren (see Troglodytes cobbi in IUCN Red List of Threatened Species) have become restricted to cat- and rat-free islands due to predatory impacts (in Atkinson, 1985 in Varnham, 2006). Feral cats and rats are likely to have decimated entire populations of Cobb's wren on some small islands (BirdLife International 2006). 降低本地生物多樣性: Felis catus have major impact on the distribution of ground nesting birds. 最後修改 : 17/06/2008 9:52:03 a.m.
