HE character “harelip and cleft palate” is definitely inherited T (REED and SNELL, 1931). Though there are various degrees of expression of harelip and cleft palate, the general condition, regardless of the types of clefts, will henceforth be designated simply as “harelip.” Harelip is not inherited as a simple dominant or a simple recessive but seems to depend upon either one recessive gene wit...

1. The functional response of post-dispersal seed predators (house mouse, Mus musculus ) to absolute densities of southern beech seed ( Nothofagus solandri var. cliffortioides ) was studied in laboratory and field trials. House mice showed a Type II (hyperbolic) functional response to seed availability and this was not modified by the presence of an alternative food source. 2. Maximum daily int...

Animal welfare depends on the possibility to express species-specific behaviours and can be strongly compromised in socially and environmentally deprived conditions. Nesting materials and refuges are very important resources to express these behaviours and should be considered as housing supplementation items. We evaluated the effects of one item of housing supplementation in standard settings ...

Although sex-linkage in animals is no longer an unusual phenomenon, its apparent rarity in rodents is noteworthy, especially in the intensively studied house mouse and rat. Hauschka, et al.,1 have presented evidence for a sex-linked lethal altering the sex ratio in the house mouse; Falconer2 recently reported a second sex-linked mutation in the house mouse. A third sex-linked mutation, Bent-tai...

To the Editor: Although the rodent that most often invades homes in North America is the house mouse, Mus musculus, the deer mouse, Peromyscus maniculatus, principal vertebrate host of Sin Nombre virus (SNV) (1), also invades homes (2), particularly in rural areas. Barring deer mice from human habitations would prevent domicili-ary acquisition of SNV. Current recommendations (3) are to prevent ...

Abstract. Change is inherent to time being transient. With the NMR-MOUSE (MObile Universal Surface Explorer) having matured into an established NMR tool for nondestructive testing of materials, this forward-looking retrospective assesses challenges faced when deployed outside a protected laboratory and how its performance quality can be maintained improved operated under adverse conditions in f...
