... it into 70% ethanol. We then examined each imago under light microscopy to determine its sex, and photographed and measured it as described above (measurements did not cover claspers in male new imagoes). Each rodent was placed in a separate plastic cage (33 cm×23 cm×13 cm) with a floor of 3–5 mm...

... requiring large forces to access the nutmeat. We, therefore, tested whether some rodent species express masticatory myosin in jaw-closing muscles. Myosin isoform expression in six Sciuridae species was examined, using protein gel electrophoresis, immunoblotting, mass spectrometry and RNA analysis...

... of parasites exploiting males rather than females. To test this hypothesis, we investigated foraging and reproductive performance of fleas ( Xenopsylla ramesis ) parasitizing male and female Meriones crassus , a gerbilline rodent. We allowed fleas to feed on groom-restricted rodents and predicted that: (1...
