Background: Clownfishes (Pomacentridae) are brightly colored coral reef fishes well known for their mutualistic symbiosis with tropical sea anemones. These fishes live in social groups in which there is a size-based dominance hierarchy. In this structure where sex is socially controlled, agonistic interactions are numerous and serve to maintain size differences between individuals adjacent in rank. Clownfishes are also prolific callers whose sounds seem to play an important role in the social hierarchy. Here, we aim to review and to synthesize the diversity of sounds produced by clownfishes in order to emphasize the importance of acoustic signals in their way of life. Methodology/Principal Findings: Recording the different acoustic behaviors indicated that sounds are divided into two main categories: aggressive sounds produced in conjunction with threat postures (charge and chase), and submissive sounds always emitted when fish exhibited head shaking movements (i.e. a submissive posture). Both types of sounds showed size-related intraspecific variation in dominant frequency and pulse duration: smaller individuals produce higher frequency and shorter duration pulses than larger ones, and inversely. Consequently, these sonic features might be useful cues for individual recognition within the group. This observation is of significant importance due to the size-based hierarchy in clownfish group. On the other hand, no acoustic signal was associated with the different reproductive activities. Conclusions/Significance: Unlike other pomacentrids, sounds are not produced for mate attraction in clownfishes but to reach and to defend the competition for breeding status, which explains why constraints are not important enough for promoting call diversification in this group.

The problem of Ovid’s Greek sources remains complex and very extensive. For the famous Pyramus and Thisbe episode, J. Lightfoot suggests that the Greek author, Parthenius of Nicaea, inspired, in part, the Latin poet. This note aims to bring a new argument in favour of this hypothesis by analysing deeply and precisely the line, Metamorphoses IV 94, in comparison with the 32nd story in Ἐρωτικὰ Παθήματα, a “note-book” collecting thirty-six love-stories.

An inheritable muscular hypertrophy was recently described in sheep and shown to be determined by the callipyge (CLPG) gene mapped to ovine chromosome 18. We demonstrate in this work that the callipyge phenotype is characterized by a non-Mendelian inheritance pattern, referred to as polar overdominance, in which only heterozygous individuals having inherited the CLPG mutation from their sire express the phenotype. The possible role of parental imprinting in the determinism of polar overdominance is envisaged. [less ▲]

A crucial aspect of predator oviposition behaviour is host plant choice, especially in hoverflies where the newly hatched offspring are unable to move a great distance to search for the appropriate prey. Such offspring must generally feed on the host plant aphids previously selected by the mother. Some factors involved in the selection of the oviposition site of Episyrphus balteatus De Geer include aphids associated to chemical stimuli, aphid colony size and host plant characteristics. Here we tested the hypothesis that there will not only be a rank order hierarchy of preference for aphid prey species reared on the same host plant but that a similar hierarchy of different host plant of one aphid species could be established. Therefore we compared the number of eggs laid on different combinations of host plant and aphid species. Vicia faba L., secondary metabolites free, Brassica napus L. and Sinapis alba L., containing low and high levels of glucosinolates respectively were used. The latter compounds are well known allelochemicals from Brassicaceae having a strong influence on specialist and generalist insects from both phytophagous and entomophagous levels. These experiments enhance the importance of tritrophic interactions in biological control of pests by underlining the host plant influence on aphidophagous predators, either directly or through the odours emitted by the phytophagous prey.

The aim of the present study was to assess the occurence of an own-age bias on age estimation performance (better performance for faces from the same age range as that of the beholder) by using an experimental design inspired from research on the own-race effect. The age of participants (10 to 14 year old children and 20 to 30 year old adults) was an independent factor that was crossed with the age of the stimuli (faces of 10 to 14 year old children and faces of 20 to 30 year old adults), the dependent measure being the accuracy of age estimation. There were 30 participants in each age group. An interaction between the two factors was expected. A two-way 2 (age of the participants)x 2 (age of the stimuli) ANOVA with repeated measures on the last factor was carried out on the accuracy scores. This analysis revealed a main effect of age of participants and of age of stimuli, and an interaction between these two factors. Children's performance was less accurate when estimating the age of adults' faces compared with children's faces. However, in both age groups, accuracy was better for children's faces than for adults' faces. [less ▲]
