Black Rats

Black rats (Rattus rattus) and house mice (Mus musculus) from Lord Howe Island were live-trapped, housed in the laboratory and tested for resistance to the anticoagulant poison warfarin. All rats fed warfarin (0.025% w/w) in their diet died within 4–12 days whereas no rats in the untreated group died. Mice fed warfarin at the same concentration over 21 days all survived. Black rats on Lord Howe Island remain susceptible to warfarin, but house mice appear resistant.

A three-year programme to eradicate Feral Cats Felis catus from the island of Baltra in the Galapagos archipelago achieved good results by initially poisoning with sodium monofluoroacetate (compound 1080) then trapping or shooting the remaining cats. The poisoning campaign removed 90% of the cats, its success being attributable to pre-baiting with unpolsoned baits to accustom cats to eating baits and placing enough baits to ensure that all cats encountered several baits within their home range. This, together with the use of metaclopromide (Pileran) as an anti-emetic, overcame a problem associated with poor retention of 1080 in thawed fish baits that limited the dose available to 1 mg 1080/bait, a quality insufficient to kill large cats. Removal of the remaining cats was delayed by a weather-induced irruption of Black Rats Rattus rattus and House Mice Mus musculus that enabled recruitment of kittens in 2002, but made cats more susceptible to trapping and shooting in 2003 when rodent populations collapsed. Since July 2003 no sign of a cat has been detected on Baltra despite extensive searching and monitoring throughout 2004. As cat abundance has decreased there have been more locally-bred Juvenile iguanas (Conolophus subcristatus) seen during annual censuses. However, such recruitment may reflect the increasing maturity and higher fecundity of iguanas repatriated from 1991 onwards rather than being a direct result of reduced cat predation alone. More time is necessary to determine the benefits of reduced cat predation on the Iguana population.

SUMMARYThe house mouse (Mus musculus) and the black rat (Rattus rattus) are reservoir hosts for zoonotic pathogens, several of which cause neglected tropical diseases (NTDs). Studies of the prevalence of these NTD-causing zoonotic pathogens, in house mice and black rats from tropical residential areas are scarce. Three hundred and two house mice and 161 black rats were trapped in 2013 from two urban neighbourhoods and a rural village in Yucatan, Mexico, and subsequently tested forTrypanosoma cruzi,Hymenolepis diminutaandLeptospira interrogans. Using the polymerase chain reaction we detectedT. cruziDNA in the hearts of 4·9% (8/165) and 6·2% (7/113) of house mice and black rats, respectively. We applied the sedimentation technique to detect eggs ofH. diminutain 0·5% (1/182) and 14·2% (15/106) of house mice and black rats, respectively. Through the immunofluorescent imprint method,L. interroganswas identified in 0·9% (1/106) of rat kidney impressions. Our results suggest that the black rat could be an important reservoir forT. cruziandH. diminutain the studied sites. Further studies examining seasonal and geographical patterns could increase our knowledge on the epidemiology of these pathogens in Mexico and the risk to public health posed by rodents.

Eradicating introduced rodents from islands restores these communities, but operations must mitigate bait uptake by non-target species to ensure adequate bait coverage, and minimize mortality of non-target species. Ingestion of toxic bait is a recognised risk for scavenging birds, but is also a concern for generalist feeders. Gough Island, Tristan da Cunha, in the South Atlantic Ocean, has introduced house mice (Mus musculus) that negatively affect the island ecosystem. It is also home to the endemic globally threatened Gough bunting (Rowettia goughensis), a generalist that may be affected by primary poisoning. We presented 26 wild individuals with non-toxic bait pellets and observed their reactions for up to 30 min, or until they flew away. While 23% of Gough buntings did not react to bait pellets, 77% showed some level of interest. Generalist feeders, such as Gough bunting, may also be at risk of primary poisoning during rodent eradication operations.

Seven taxa of raptorial birds were experimentally fed a controlled sample of 50 house mice (Mus musculus). Bones recovered from the pellets were examined for interspecies variability in preservation to assess the potential contribution of specific raptors to patterning in fossil assemblages. Quantitative analyses demonstrate that patterns in bone fragmentation may assist in the identification of particular raptor species as depositional agents in small mammal assemblages.

The house mouse, Mus musculus, was established in the early 1900s as one of the first genetic model organisms owing to its short generation time, comparatively large litters, ease of husbandry, and visible phenotypic variants. For these reasons and because they are mammals, house mice are well suited to serve as models for human phenotypes and disease. House mice in the wild consist of at least three distinct subspecies and harbor extensive genetic and phenotypic variation both within and between these subspecies. Wild mice have been used to study a wide range of biological processes, including immunity, cancer, male sterility, adaptive evolution, and non-Mendelian inheritance. Despite the extensive variation that exists among wild mice, classical laboratory strains are derived from a limited set of founders and thus contain only a small subset of this variation. Continued efforts to study wild house mice and to create new inbred strains from wild populations have the potential to strengthen house mice as a model system.
