Ten microsatellite loci were isolated from the earwig Labidura riparia (Pallas, 1773). The polymorphism of the loci was assessed in 24 individuals from one population. The number of alleles ranged from four to 11 alleles and observed and expected heterozygosities from 0.250 to 0.833 and from 0.551 to 0.861, respectively. 相似文献

Quantitative and qualitative measurements of DNA were used to compare faecal sample storage in ethanol and silica with a novel method (two‐step) in which samples are soaked in ethanol and then desiccated with silica. Silica‐preserved samples had the lowest DNA concentrations. The two‐step method yielded significantly more DNA in high quality samples (average DNA concentrations > 100 pg/µL with all storage methods). However, for lower quality samples, the ethanol and two‐step methods performed similarly. The amounts and rates of sample degradation were not strongly affected by storage method and neither was the percentage of target DNA (< 1%) obtained from the samples. 相似文献

Study on Social Interactions between Male and Female Genets (Genetta genetta L.): Relations between Scent Marking and Aggression The aim of this work was to study the relations between marking behaviour and aggression in genets (Genetta genetta L.). Observations on social interactions were made on a socially stable pair and during encounters between unfamiliar pairs. In the first case, there appeared to be a relationship between marking activity in the male and aggression. During aggression periods, marking with the ano-urogenital region increased in the male and decreased in the female. Another striking variation concerned flank rubbing and hindleg rubbing. In both male and female these marking frequencies increased significantly during aggression periods and flank rubbing was modified by visual cues. Data recorded during encounters between unfamiliar pairs (one male being introduced in a female's cage) showed that agonistic behaviours were released through visual cues in females and olfactory cues in males. The same changes in marking frequencies were observed. These results also showed that ano-urogenital marking was inhibited in females during aggression periods. The adaptative significance of these phenomena is discussed. 相似文献

Memorization of Scent Marks in Genets (Genetta genetta L.): Duration of Female Memory of Male Scent Marks The aim of this work was to study the memorization of scent marks of known males by females in genets (Genetta genetta L.). An attempt was made to determine how long, after separation from a given male, females could discriminate between his scent marks and those of strange males. Significant differences in sniffing duration at the scent marks were observed nine weeks after separation. These results showed that olfactory cues could permit individual recognition in genets, and that memorizing the scent marks could also act in the regulation of aggressive behaviour in free-living animals. 相似文献
