Blood - lactate lice have uncover a few of their host ’s secret . Scientists interested in the big - eyed , nocturnal brown mouselemurturned to their lice to better understand this primate ’s social fundamental interaction and to see how the parasite open among them .
One of the smallest order Primates on the satellite , the chocolate-brown mouse lemur is infect by a parasitic louse calledLemurpediculus verruculosus . The insect is only known to taint the lemur and can not live long off of lemur skin .
A brown mouse lemur. By tracking the lice that infect them, scientists came to better understand how these shy, nocturnal primates interact with each other.
In the rain forest of Madagascar , researchers caught lemur and the lice be on them . On the lice , they painted a serial of colored dots in nail varnish to place lice live on an individual lemur ’s ear . Later , they recaptured the lemurs to see if the lice had moved and to whom , let out grounds of the habit of these unmanageable - to - study creatures . [ photo : Wacky Madagascar animate being ]
They traverse 76 transfers between 14 animals — all male — over the course of four week , a remarkably high charge per unit of lice sharing that coincidedwith the nurture season . This may have been a solvent of more conflicts among male over females , according to the investigator .
There was no relationship between the eld of a male lemur and his part in biting louse sharing .
" The untested male in the study had the bad biting louse infestation , but only donated one louse , indicating a low number of interactions , while the eldest male person , who also had a grave plague , seem to be more sociable , gather lice from many presenter , " said Pb researcher Sarah Zohdy from the University of Helsinki in a pressure exit issued by journal publisher BMC Central . " Other males appeared to be ' superspreaders ' donating but not collecting lice "
The pattern of lice sharing also revealed that the lemurs journey much outstanding distance and interacted over a broad area than thought , Zohdy and colleagues concluded .
The lice - paint approach they used has the potential drop to help researcher get a better handle on social interactions and parasite central amongother problematic , lice - infected species , they write in a study published online Monday ( March 26 ) in the daybook BMC Ecology .
