After a long period of neglect, the study of teaching in nonhuman animals is beginning to take a more prominent role in research on social learning. Unlike other forms of social learning, teaching requires knowledgeable individuals to play an active role in facilitating learning by the naive. Casting aside anthropocentric requirements for cognitive mechanisms assumed to underpin teaching in our...

This paper investigates how young pied flycatchers, Ficedula hypoleuca, and blackcaps, Sylvia atricapilla, interpret and use celestial cues. In order to record these data, we developed a computer-controlled version of the Emlen funnel, which enabled us to make detailed temporal analyses. First, we showed that the birds use a star compass. Then, we tested the birds under a stationary planetarium...

The focus of this paper is the syntax of inverse scope in Hungarian, a language that largely disambiguates quantifier scope at spell-out. Inverse scope is attributed to alternate orderings of potentially large chunks of structure, but with appeal to base-generation, as opposed to nonfeature-driven movement as in Kayne 1998. The proposal is developed within mirror theory and conforms to the assu...

Theory predicts that animals in adverse conditions can decrease individual risks and increase long-term benefits by cooperating with neighbours. However, some empirical studies suggest that animals often focus on short-term benefits, which can reduce the likelihood that they will cooperate with others. In this experimental study, we tested between these two alternatives by evaluating whether in...

With the access to draft genome sequence assemblies and whole-genome resequencing data from population samples, molecular ecology studies will be able to take truly genome-wide approaches. This now applies to an avian model system in ecological and evolutionary research: Old World flycatchers of the genus Ficedula, for which we recently obtained a 1.1 Gb collared flycatcher genome assembly and ...

Le lipome intraosseux est une tumeur bénigne rare représentant 0,1% de l'ensemble des tumeurs squelettiques. Au membre inférieur, sa localisation au calcanéum est retrouvée dans 15% des cas. Son étiopathogénie demeure imprécise et reste partagée entre origine tumorale bénigne et post-traumatique. Elle touche avec légère prédominance féminine, le sujet de la quatrième ou cinquième décade. La cli...

Passerine birds use a variety of indirect cues to make territory location decisions. These birds can also distinguish herbivore-damaged plants from undamaged ones during foraging, even when they cannot see the herbivorous larvae or damaged leaves. To test the possibility that also the territory choice of passerines is affected by herbivoreinduced plant cues, we established territories with and ...

Nous rapportons le cas d’un patient de 66 ans qui consultait pour un nodule plantaire asymptomatique, augmentant progressivement de volume depuis 6 ans. L’examen retrouvait une tuméfaction du bord latéral du pied droit, de 2 cm de diamètre, de consistance dure, sensible, bien limitée, adhérente au plan superficiel et sans modification de la peau en regard. L’échographie des parties molles du pi...

This paper discusses how predicate-initial (VOS) order in Malagasy is derived, and the implications of this derivation for general theories of word order. Malagasy clauses are comprised of a predicate phrase followed by a constituent here called the TRIGGER, which occupies the specifier of an A’-position (provisionally labelled TopP). I argue against an analysis where TopP projects its specifie...
