In human communities social learning (i.e., learning by the observation of knowledgeable individuals) plays an important role; it shapes cultures, traditions, and cognition. Dogs seem to be an ideal system for modeling human cognition from the social learning aspect. The present review offers a short overview on the relevant general theories of social learning, discusses the adaptive value of social learning, introduces dog as a model system, presents evidence for different forms of social learning in dogs and argues for practical implications that social learning might have in this species. 相似文献

Chinese cabbage is a leafy green with great economic potential, mostly in those areas where it has not yet been widely cultivated, but its demand is increasing, due to its high nutritional and therapeutic value. The experimental factors involved three cultivars of Chinese cabbage, different irrigation, and fertilization treatments. The main aims of the present research were to establish the influence of water and fertilization management on Chinese cabbage chemical composition in an organic cropping system and to determine relations between the organic fertilizers and cabbage leaf macroelements, essential microelements, and heavy metal concentrations. The results showed that sheep manure was richer in almost all the studied elements, including heavy metals; plants fertilized with this manure have higher levels of heavy metals; irrigation had a secondary effect on the decreasing heavy metal concentration in plants; and plants fertilized with biofertilizers showed high amounts of potassium (K), magnesium (Mg), sodium (Na), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn). 相似文献

In order to investigate haemotropic Mycoplasma (formerly Eperythrozoon) infection of goats, blood samples and blood-sucking lice (Linognathus stenopsis) were collected in two goat herds. DNA was extracted from 20 blood samples and from 49 lice allocated to six pools according to host individuals. Haemoplasma infection was detected in four goats by real-time PCR. From the sample with the highest bacterial load the simultaneous presence of M. ovis and 'Candidatus M. haemoovis' was demonstrated by cloning and sequencing. Louse pools were haemoplasma negative, including those from bacteraemic animals. However, not only were Anaplasma inclusion bodies seen in blood smears from goats, but relevant PCR-positivity was also detected among lice. This is the first report of a molecular investigation on caprine haemoplasmas, including analysis of their bloodsucking lice. In summary, goats are susceptible to both molecularly characterised ovine haemoplasmas. On the other hand, goat sucking lice (L. stenopsis) do not appear to be potential vectors of these agents. 相似文献

OBJECTIVE: Recombinant feline interferon omega (rFeIFN-omega), a type I IFN, may have the potential to limit virus replication and associated clinical signs when administered early on in the course of feline herpesvirus type 1 (FHV-1) infection and reactivation, respectively. The effect of rFeIFN-omega pretreatment on the course of subsequent FHV-1 infection in cats was investigated. ANIMALS STUDIED: Nine SPF cats were divided into an IFN group (n = 5) and a control-group (n = 4). PROCEDURES: The IFN group was pretreated for 2 days with 10 000 units rFeIFN-omega twice a day topically into both eyes and 20 000 units rFeIFN-omega once a day orally, whereas the control group was mock-treated. Subsequently all cats were infected with FHV-1. Samples for FHV-1 DNA detection and quantitation, virus isolation, and titration of FHV-1 antibodies were collected. Clinical and ocular signs were recorded and scored. RESULTS: Courses of median individual clinical and ocular scores and virus load did not differ significantly between both groups using anova for repeated measurements. Analysis (anova) of each individual ocular parameter revealed significantly high scores for epithelial keratitis (P = 0.016) in the IFN group compared to the control group. Periods of virus shedding did not differ significantly between both groups using the Wilcoxon rank sum test. CONCLUSIONS: Results indicated a lack of beneficial effects of rFeIFN-omega pretreatment in the course of primary FHV-1 infection in cats. 相似文献
