Animal tracks, bigger than rat and smaller than coyote, lead away into the dusty gloom.
Weasels prey chiefly on mice and rats and small birds, and must be crafty hunters to be successful; they are small enough to chase a field mouse down its underground tunnel.
Even with what are meant to be the most "biosecure" industrial animal factories, like Bernard Matthews' turkey buildings in Norfolk, it is simply ridiculous to suggest animals like mice, rats, and small birds can ever be completely excluded.
The species is not in immediate danger as the majority of its habitat is protected forest, but introduced species, such as rats and small Asian mongooses, habitat reduction, and natural disasters represent potential threats to the population.
This also explains why P. irritans and T. penetrans, relatively low host-specific ectoparasites, occurred only in rural areas, where dogs were frequently in contact with other natural host animals, such as pigs, rats and small ruminants [ 47- 49].
In contrast, tumor incidence in female rat colon and small intestine was unaffected (P > 0.1) by BB (Table 4).
Moreover, another connexin, Cx32, colocalizes with tight junction proteins ZO-1 and ZO-2 in rat hepatocytes, and small gap junction plaques were found within tight junction strands.
This peptide is unrelated to NMU in sequence but has been identified in rat brain and small intestine extracts, suggesting that it constitutes a mature cleavage product (22).
124I-labeled radiotracers [124I]CKIA and [124I]CKIB were used in cell uptake studies as well as biodistribution studies in Wistar rats and small-animal PET in tumor-bearing mice.
The extinction of the Antillean rice rats, including Pennatomys, may have resulted from the introduction of exotic animals such as the black rat and the small Asian mongoose (Herpestes auropunctatus) to the Lesser Antilles.
