Johanna Meijer and Yuri Robbers at Leiden University
Medical Centre in the Netherlands set up exercise wheels at two sites
where wild mice live, and collected video for more than three years.
They found that the median running speed of wild mice was lower than
that of their captive counterparts, but wild mice reached higher maximum
speeds. The animals were initially attracted to the equipment by food
rewards, but continued to use the wheels when food was absent.
“when running wheels are placed in nature, they are frequently used by
wild mice, also when no extrinsic reward is provided. Bout lengths of
running wheel behaviour in the wild match those for captive mice. This
finding falsifies one criterion for stereotypic behaviour, and suggests
that running wheel activity is an elective behaviour.”
Ez igazán édes, szuper meg minden, de pont az LUMC-ben kutatnak
egéretológiát, amikor sehol semmi esély egy normális kutatói
támogatásra? Erre költik azt a kevés pénzt?
Vagy csak annyira nincs pénzük, hogy kiszanálták a laboregerek
mókuskerekét, kiraktak hozzá egy kamerát, aztán ebből írtak egy PNAS
cikket?!?!?
