The behaviour of licking the everted rectum in shrews, hitherto referred to as "coprophagy" or "refection" is reviewed. To avoid confusion with "true" faeces-eating, it is proposed to persistently use the descriptive term "rectum-licking" when referring to this phenomenon. The behaviour is characterized by the animal everting the rectum by a series of abdominal contractions and licking it in a curled-up posture, apparently ingesting a yet undetermined substance often described as a "milky white fluid". This behaviour has been reported repeatedly, but most previous observations are only fragmentary and the accounts on the generality, frequency, rhythm, timing, mechanism, and functions of the behaviour are not all consistent. Rectum-licking is certainly an infrequent and elusive behaviour, which can be mistaken for other behaviours that share the same curled-up posture. Further studies are required to elucidate this behaviour.

The food-handling and reingestive behaviour of feces by Ctenomys pearsoni Lessa and Langguth, 1983, was studied in the laboratory. All animals studied handle grasses with dexterity with one or both forepaws, and vigorously shaked it up and down before ingestion. Reingestion of feces occur frequently during resting periods and between feeding bouts. While performing both behaviours, C. pearsoni adopt a posture that not increase its height, what could be considered as and adaptation to the burrow space. Some convergences and divergences in the patterns of food-handling and reingestion of feces between Ctenomys and other subterranean rodents genera were remarked. We propose that the food-handling pattern is related to the cleaning of food; while the reingestion pattern might be related to water economy and to recover some particular nutrients.

The response of coprophagous dung beetles Geotrupes stercorosus (Scriba, 1791) to the additional food supply in the habitat was examined, as well as their food preference, the effect of food and the daily rhythm of activity, and population density. The study was conducted in the summer and early autumn periods in four years (1998–2002) in a mixed coniferous forest Leucobryo-Pinetum (Matuszkiewicz, 1962) located in central Poland (52°20’N, 27°25’E). The insects were captured in baited traps functioning as Barber’s traps do. They were marked by clipping wing covers (based on the CMR technique). In total, about 31 000 individuals were caught and marked. It has been found that among faeces of different mammals, the faeces of forest rodents are the most attractive food for dung beetles. Food stimulates movements of beetles towards its source (foraging activity). The peak activity coincides with the afternoon hours (5.43 individuals per trap, on average, P ≤ 0.0001 as compared with the other periods of the day and night). There were years with a high number of captures (11.9 individuals per trap per day) and a low searching activity, and years with a low number of captures (5.06 individuals per trap per day) and a high searching activity. To compare differences in the number of beetles captured in pitfall traps with their genuine numbers in the habitat, the method of square sampling was used for evaluating their density (1.13 × 103 individuals per ha). There were days when the locomotor activity of the dung beetles was low and days when the number of captured beetles exceeded several times their genuine density on the area of 1 ha.

Parascaris and cyathostome nematodes in foals: parasite in transit or real infection?

Faecal egg counts were performed in 187 foals of a large Polish stud farm between February and September 2007. Eggs of Parascaris equorum were present in faeces of 7% and those of cyathostomins in 13% of the foals aged less than 194 days. Information dealing with age of foals and/or efficiency of ivermectin treatment as well as the nematode parasite prepatent periods, it can be conducted that most of the infections recorded on the basis of faecal egg counts were false-infections in animals up to the age of six months, probably due to the ingestion of infected faeces of their dam or some other horses.
