Abstract:
... According to the European Union Council Directive 2008/120EC, measures to minimise the risk for tail biting shall be taken before practicing tail docking, e.g. provision of manipulable material. Still, >90% of the pigs within EU are tail docked. Thus, management routines for providing manipulable material in commercial pig production are needed. The aim of this study was to investigate how an incr ...

Abstract:
... The gene regulatory networks underlying Ciona notochord fate specification and differentiation have been extensively investigated, but the regulatory basis for regionalized expression within the notochord is not understood. Here we identify three notochord-expressed genes, C11.331, C12.115 and C8.891, with strongly enriched expression in the secondary notochord cells at the posterior tip of the ta ...

Abstract:
... In several ungulate species, the tail is used to communicate sexual states of the female. However, the role of the tail or its movements in the sexual attractiveness of the ewe and sexual activity of the ram is still unknown. Two experiments were performed to determine the influence of the tail of the ewe in these aspects. In Experiment 1, 25 rams were individually tested in random order on two ex ...

We discovered three patterns of vocal activity not previously described. When barbastelles investigated the roost entrance, calls resembling the approach phase of echolocation were produced consisting of a group of 10 or more broadband pul ...

Pig groups were of equally distributed mixed gender and males were castrated during the first days of life. Two treatment groups were investigated over nine batches with on average 194.4 (SD 14.0) pigs per batch. One treatment group (n = 810) received a con ...

... It was the aim of the study to investigate the effect of a prolonged suckling period and group housing before weaning on tail biting in undocked nursery pigs. To do this, experiments with three treatment groups were investigated. In the first group, pigs were conventionally housed in pens with farrowing crates for a four-week suckling period (SH-4). In the second group, suckling was prolonged to f ...

Abstract:
... Tail biting is one of the largest problems in intensive pig production among finishers. Currently, tail docking is performed to minimize tail biting, such as bleeding, sores, infection and amputation, however, due to legislation and consumer demand, there is a need for finding other alternatives. The aim of this study was to investigate the effect of pen environment on the prevalence of pen-mate d ...

Abstract:
... It has been reported that individuals of cooperative breeding species occasionally interfere with the work of other group members. However, the occurrence and function of this behaviour are controversial. In the naked mole rat (Heterocephalus glaber), a eusocial mammal, individuals frequently perform ‘tail-tugging’ behaviour, in which an actor holds the tail of another individual with the mouth an ...

Abstract:
... In fossilised vertebrates, the presence of soft tissues is the most obvious way to determine aspects of anatomy and functional morphology; however, occurrences are rare and other lines of evidence must be sought to indicate its extent and strength. For example, pterosaurs possessed a large wing membrane that enabled powered flight but other tissues are not widely preserved. A semi-quantitative ana ...

Abstract:
... Many lizards have contrasting longitudinal body stripes, thought to dazzle predators during motion, thereby misdirecting attacks to the expendable tail. To understand what promotes evolution of such “dazzle” patterns, we performed a touchscreen predation experiment with humans and found stripes to be more effective in smaller prey. Comparisons across lizard species showed that stripes are correlat ...

Abstract:
... To substantiate the claim of a relationship between generation gland morphology and degree of body armour in cordylid lizards, we studied the nine species in the genus Smaug. We predicted that well armoured species in this clade will have multi-layer generation glands, and lightly armoured species two-layer glands. Gland type was determined using standard histological techniques after sectioning a ...
