    Early learning of volatile chemical cues leads to interspecific recognition between two ant species

    Nestmate recognition in social insects generally involves matching a label to the template that is acquired through the early learning of non-volatile cuticular hydrocarbon cues. However, a possible role of th...

    Hammering, mauling, and kissing: stereotyped courtship behavior in Cardiocondyla ants

    Sex appears to be a rather prosaic and casual event in the life of most social Hymenoptera. In contrast, mating in the ant genus Cardiocondyla is regularly preceded by a prolonged and stereotypic courtship displa...

    Individual flexibility and choice of foraging strategy in Polyrhachis laboriosa F. Smith (Hymenoptera, Formicidae)

    We report in this study that the tree-dwelling African ant Polyrhachis laboriosa (Formicinae) uses different foraging strategies according to the size of the available food sources. We demonstrate that a recruit...

    Ritualized behavior during competition for food between two formicinae

    Polyrhachis laboriosa andCamponotus brutus are two syntopic ants of the African equatorial forest. Although they occupy two different ecological niches (nesting area, diet, rhythms of activity), they are in comp...

    The Tectonic Regimes Along the Convergent Border of the Aegean Arc from the Late Miocene to the Present; Southern Peloponnesus as an Example

    Field analysis of fault kinematics demonstrates changes in the tectonic regime on the Aegean Arc border. During the Pliocene-Early Pleistocene extensional tectonics were active; extension trended radial to the...

    Aquatic macrophyte communities as bioindicators of eutrophication in calcareous oligosaprobe stream waters (Upper Rhine plain, Alsace)

    The results cover a statistical analysis of the correlations between aquatic macrophyte communities and chemical parameters (N−NH4, N−NO3, P−PO4, COD, Temperature, dissolved O2, Cl) in unpolluted hard waters (upp...

    Global patterns of tectonic stress

    Regional patterns of present-day tectonic stress can be used to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity. Most intraplate regions are characterized by a compressi...

    Late Cenozoic Rotatons Along the North Aegean Trough Fault Zone (Greece); Structural Constraints

    The NE-SW to E-W striking North Aegean trough fault zone takes up the righe handed strike-slip motion of the North Anatolian Fault at its western termination. Paleomagnetic measurements suggest that its southe...

    Paleomagnetic Study of the Neogene Formations of the Aegean Area

    New paleomagnetic data have been obtained from middle Miocene to Pliocene sedimentary and volcanic formations in central Aegea, in western Anatolia and in the Antalya basin in southern Anatolia. Together with ...

    Field evidence for active normal faulting in Tibet

    Crustal thickening does not now occur in southern Tibet. Field observations made during the Chinese–French expedition of 1980 support an earlier hypothesis based on a combined analysis of satellite images and ...

    The Tibetan side of the India–Eurasia collision

    Results are reported from the 1980 joint French–Chinese field expedition in Tibet. The area covered was from the High Himalaya in the south, to the region of Nagqu ∼250 km north of Yangbajain. Ophiolites in th...

    Intra-plate deformation: a quantitative study of the faults activated by the 1978 Thessaloniki earthquakes

    THE Thessaloniki region suffered from damaging seismic activity during the summer of 1978. During both major shocks that took place on the 24 May (M, 5.5) and 20 June (M, 6.5), manifestations of faulting could be...
