Mate choice is the outcome of sexual preference for partners carrying specific signals. Thus, mating among conspecifics (homogamy) depends on the occurrence of species recognition systems. We asked what happens if populations diverge, and we investigated female sexual preference between two subspecies of the house mouse in populations from the borders of a hybrid zone ( Jutland, Denmark). We us...

The house mouse (Mus musculus) has been spread throughout the world by the actions of humans. It causes severe impacts to native ecosystems, especially in areas where there are no native mammals. It is possible to eradicate mice from islands but they are harder to eradicate than rats. A review of reported eradication attempts found that 17 attempts on 45 islands worldwide failed; a failure rate...

House mice (Mus musculus) pose a threat to the native flora and fauna on islands, and can cause significant damage wherever they have been introduced. Methods used to eradicate invasive rodents, like house mice, at high population densities may not be appropriate for intercepting them at lower densities. A better understanding of the immediate behavior of house mice when first introduced to a n...

The Secret Behind the Door. (Featuring Joan Bennett and Michael Redgrave. 8,865 ft. 99 mins.) Psychiatrists, presumably, are used to strange tales from their patients. Sometimes they may be inclined to think that nothing about human beings will surprise them. There, however, they underestimate the film-writer's imagination, for in The Secret Behind the Door there is portrayed a hero whose parti...

Pneumonia is a health problem in the world with high mortality rate both developing countries and developed such as America, Canada European countries. In Indonesia, number three cause of death after cardiovascular disease tuberculosis. Low socioeconomic factors increase mortality. This infection generally spread from someone who exposed neighborhood or has direct contact infected people throug...

background and objective: establishing and implementing high quality of nursing care for patients is the main objective of any nursing education system. however, the lack of proficient nurses all over the world led to a competition and collaboration among countries to train as much nurses with high skills and knowledge as possible. this paper aims at studying and comparing two nursing education...

These two subspecies of house mouse were found to differ in their social behaviour, the former being less aggressive than the latter. The paternal effect on aggression (observed repeatedly in laboratory mice) was not found. However, F2 generation mice were less aggressive than those from the F1 generation, and the maternal effect was also significant in a homogenous test set.
