The mouse (Mus musculus) is the most commonly used mammal in biomedical research and can easily be restrained by both hand and by a device. Restraining animals causes stress that not only decreases the animal’s wellbeing, but may also influence the research results. The first …
Epizootier som drabbat marina däggdjur och lett till storskaliga dödsfall har uppmärksammats runt om i världen de senaste decennierna. Höga halter av persistenta miljökontaminanter såsom DDT (diklordifenyltrikloretan) och PCB (polyklorerade bifenyler) har uppmätts hos djur som …
… essential trace element that is involved in several physiological functions in mammals. Mostly, Se is bound to proteins, many of them with enzymatic functions. A group of seleno-depending enzymes, glutathione peroxidases (GSH-Px’s), are important as antioxidants and protects …
Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor …

… This is interesting as the human cortex greatly resembles that of other mammals, elephants included, and the results might therefore be extrapolated onto other species. Furthermore, the elephant cortex has been shown to consist of a more intricate neuronal network, possibly …
… many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar bears, and finally how they affect the animals reproduction, with reproductive …
a retrospective pilot study of SAA levels in dolphins, elephants and tapirs at Kolmården Wildlife Park
The veterinary handling of wildlife, both in zoos and in the wild, commonly requires that the patients need to be captured and immobilized for examination or treatment. This emphasises the need for quick, on-site, laboratory equipment, in order to minimize the analysis time and …
Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with …
Möjlig interaktion och effekt på lokal biodiversitet
… report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that …
… waterliving animals, but the bacterium can also be recovered from humans, mammals (of which cats are over-represented), birds, insects and poikilothermic animals. P. shigelloides is an opportunistic bacterium and reports about its role as a human pathogen is increasing. There …
