         一般影響

    挪威鼠(Rattus norvegicus)會吃植物種子和幼苗,限制植物再生。它們大多捕食比自己小的動物如爬行動物,小鳥,鳥卵和淡水及潮間帶物種。挪威會老鼠吃糧食作物,也會在人類的食物上排尿,排便,污染食物。額外的經濟損失是啃咬電纜,以及傳播疾病。
    某些地區挪威鼠(Rattus norvegicus)和褐家鼠(Rattus rattus)都會經由跳蚤傳播鼠疫(鼠疫(Yersinia pestis))。近年來已經在馬達加斯加爆發一系列疫情(Boiser 等人, 2002)。



         地點特有的影響:
    Intermares (Brazil) English 
    威脅瀕危物種: Predation by the Rattus norvegicus on eggs and hatchlings of the endangered Hawksbill turtle (see Eretmochelys imbricata in IUCN Red List of Threatened Species) during the 2003/2004 and 2004/2005 nesting season was identified as a the main cause of poor nesting rates (losses of close to 3000 eggs and hatchlings were estimated) (Zeppelini et al. 2007).
    Anegada Is. (British Virgin Islands) English 
    威脅瀕危物種: Rattus norvegicus may predate young 'Critically Endangered (CR)' Anegada Is. rock iguana (see Cyclura pinguis in IUCN Red List of Threatened Species) on Anegada Is., and also compete with them for food resources (Veitch, 1998 in Varnham, 2006).

    降低本地生物多樣性: On Anegada Is. rats will be having a detrimental impact on birds, lizards and frogs through competition for food and predation of eggs, young and adults (Veitch, 1998 in Varnham, 2006).

    降低本地生物多樣性: On Anegada Is. rats will be having a detrimental impact on birds, lizards and frogs through competition for food and predation of eggs, young and adults (Veitch, 1998 in Varnham, 2006).
    Langara Is. (Canada) English 
    降低本地生物多樣性: Rattus norvegicus is implicated in the extirpation or decline of previously large seabird populations on Langara Island (Howald et al., 1999).
    Cayman Brac (Cayman Islands) English 
    捕食: Rattus norvegicus is a predator on native snakes and lizards, including hatchling rock iguanas, and nesting birds (Burton, 2003 in Varnham, 2006).

    棲地改變: Rattus norvegicus is also likely to be having impacts on regeneration of native flora due to seed consumption (Burton, 2003 in Varnham, 2006).
    Grand Cayman (Cayman Islands) English 
    棲地改變: Rattus norvegicus is also likely to be having impacts on regeneration of native flora due to seed consumption (Burton, 2003 in Varnham, 2006).

    降低本地生物多樣性: Rattus norvegicus is a predator on native snakes and lizards, including hatchling rock iguanas, and nesting birds (Burton, 2003 in Varnham, 2006).
    Little Cayman (Cayman Islands) English 
    捕食: Rattus norvegicus is a predator on native snakes and lizards, including hatchling rock iguanas, and nesting birds (Burton, 2003 in Varnham, 2006).

    棲地改變: Rattus norvegicus is also likely to be having impacts on regeneration of native flora due to seed consumption (Burton, 2003 in Varnham, 2006)
    Falkland Islands (Malvinas) (sub-Antarctic) English 
    威脅瀕危物種: Brown rats are likely to have destroyed whole poulations of 'Vulnerable (VU)' Cobb's wren (see Troglodytes cobbi in IUCN Red List of Threatened Species) and many other land and seabirds, especially burrowing petrels (BirdLife International 2006). Breeding of the Tussock bird (Cinclodes antarcticus antarcticus) has become restricted to cat- and rat-free islands. Reduction of small petrels including Antarctic prion (Pachyptila desolata) has occurred on rat-inhabited islands (In Atkinson, 1985 in Varnham, 2006).

    棲地改變: Brown rats may have some impacts on vegetation.

    降低本地生物多樣性: The presence of rats on islands is negatively correlated with the presence of seven species of native passerines (Varnham, 2006).
    Isle of Man English 
    捕食: There is concern that Rattus norvegicus could be taking eggs from ground nesting birds (Charter, 2004 in Varnham, 2006).
    Japan English 
    捕食: Rattus norvegicus preys on the apple snail (Pomacea canaliculata), an important pest of rice, in Japan (Yusa et al., 2000).
    Rodrigues Is. (Mauritius) English 
    吃草: Rattus norvegicus causes damage to the vegetation of Mascarene islands. Predation of fallen palm fruit and seedlings is a major problem.
    Rasa Is. (Mexico) English 
    降低本地生物多樣性: Rats and mice may be responsible for the absence of nocturnal hole and crevice nesting birds on Rasa Island (Donlan et al., 2000).
    Rakino Is. (New Zealand) English 
    捕食: Rattus norvegicus was probably responsible for extirminating the grey-faced petrel from Rakino Island (ARC, 2002).
    Campbell Is./Motu Ihupuku (sub-Antarctic) (New Zealand) English 
    捕食: It is probable that Norway rats have caused catastrophic declines in the numbers of ground-nesting birds, but no particular case has been properly documented (SPREP, 2000).
    Whale (Moutohora) Is. (New Zealand) English 
    捕食: Rattus norvegicus preys on the eggs and chicks of the grey-faced petrel (Pterodroma macroptera gouldi) on Whale Island (Imber et al., 2000).
    Kayangel Is. (Palau) English 
    傳播疾病: Rattus norvegicus are known to affect community health in Palau by acting as disease vectors, exposing citizens to gastrointestinal illnesses and leptospirosis through water supplies

    威脅瀕危物種: Ground birds such as the Micronesian megapode (see Megapodius laperouse in the IUCN Red List of Threatened Species) are particularly vulnerable to introduced predators such as rats and cats.

    經濟 /民生: Rattus norvegicus are causing economic losses by damaging crops including papaya and corn.
    Azores (Portugal) English 
    傳播疾病: Rattus norvegicus plays a significant role as a maintenance host of leptospirosis in the Azores.

    捕食: Rats are a major factor in determining the distribution of Puffinus spp.in the Azores (Pitta Groz et al., 2002).
    Reunion (La Reunion) English 
    吃草: Rattus norvegicus causes damage to the vegetation of Mascarene islands. Predation of fallen palm fruit and seedlings is a major problem.
    Saint Helena English 
    降低本地生物多樣性: Rattus norvegicus are highly omnivorous, eating plants, invertebrates and young birds (Ashmole and Ashmole, 2000 in Varnham, 2006). They may predate on 'Critically Endangered (CR)' endemic wirebird's (see Charadrius sanctaehelenae in IUCN Red List of Threatened Species) chicks and eggs (McCulloch and Norris, undated in Varnham, 2006).
    Fregate Is. (Seychelles) English 
    滋擾人類: Rattus norvegicus were a nuisance to the plantation and hotel on Fregate Island (Millet and Shah, 2001).

    降低本地生物多樣性: Rattus norvegicus impacted on the avifauna and invertebrates of Fregate Island (Millet and Shah, 2001).
    Sth. Georgia and Sth. Sandwich Iss (sub-Antarctic) English 
    威脅瀕危物種: Breeding of the 'Near Threatened (NT) Antarctic pipits (see Anthus antarcticus in IUCN Red List of Threatened Species) and South Georgia pintails (Anas georgica georgica) has reportedly become restricted to rat-free habitats (in 8). However, other more recent sources say that although rats may have reduced pintail numbers and affected breeding success they have not eliminated them, and pintails are found all over South Georgia (Poncet, 2003 in Varnham, 2006).

    捕食: Rattus norvegicus take eggs and young of most burrow-nesting small petrels, and also eat penguin chicks (McIntosh and Walton, 2000 in Varnham, 2006). Other sources suggest they are only likely to predate weak or dead penguin chicks (Poncet, 2003 in Varnham, 2006).

    降低本地生物多樣性: Rattus norvegicus are known to eat native plants (esp. Paradiochloa flabellata, a tussock grass), as well as invertebrates and carrion (Leader-Williams, 1985 in Varnham, 2006).
    United Kingdom (UK) English 
    傳播疾病: Rattus norvegicus present a zoonotic disease risk in the UK.

    滋擾人類: Rattus norvegicus causes damage to stored food and structures in the UK.
    Canna Is. (United Kingdom (UK)) English 
    降低本地生物多樣性: Norway rats threaten the seabird populations of Canna Island, as well as the native woodmouse.
    Lundy Is. (United Kingdom (UK)) English 
    降低本地生物多樣性: Rattus rattus and R. norvegicus threatened breeding seabirds on Lundy Island, such as the manx shearwater and puffins (Appleton et al., 2002).
    Hawaii (United States (USA)) English 
    捕食: Rattus norvegicus in Hawaii are thought to be responsible for suppressing seed regeneration of endemic plants, reducing populations of native snails, and significantly limiting breeding success of many native birds (Pitt, 2004).
