    This article provides a compilation of the taxa introduced to science by the late Dr. MichelBrancucci, Basel, and of the taxa named in honour of him. We provide details of nomenclatorial value such asholotype depository (for species described by Michel Brancucci), page number of the original description andtype locality. References of the original descriptions are given in full and the actual publication dates werethoroughly checked. Indices to all taxa complete this article and make it a searchable catalogue

    Skeletal trade-offs in coralline algae in response to ocean acidification

    Ocean acidification is changing the marine environment, with potentially serious consequences for many organisms. Much of our understanding of ocean acidification effects comes from laboratory experiments, which demonstrate physiological responses over relatively short timescales. Observational studies and, more recently, experimental studies in natural systems suggest that ocean acidification will alter the structure of seaweed communities. Here, we provide a mechanistic understanding of altered competitive dynamics among a group of seaweeds, the crustose coralline algae (CCA). We compare CCA from historical experiments (1981-1997) with specimens from recent, identical experiments (2012) to describe morphological changes over this time period, which coincides with acidification of seawater in the Northeastern Pacific. Traditionally thick species decreased in thickness by a factor of 2.0-2.3, but did not experience a change in internal skeletal metrics. In contrast, traditionally thin species remained approximately the same thickness but reduced their total carbonate tissue by making thinner inter-filament cell walls. These changes represent alternative mechanisms for the reduction of calcium carbonate production in CCA and suggest energetic trade-offs related to the cost of building and maintaining a calcium carbonate skeleton as pH declines. Our classification of stress response by morphological type may be generalizable to CCA at other sites, as well as to other calcifying organisms with species-specific differences in morphological types

    Paussus brancuccii sp.nov., an unusually abundant species of the Paussus jousselinii group from Laos and South China (Coleoptera, Carabidae, Paussinae, Paussini)

    A new myrmecophilous species of flanged bombardier beetles is described from northeastern Laosand China (Guangxi), Paussus brancuccii sp.nov. This species stands out from other members of the Paussusjousselinii group and most other Paussines by the large number of specimens available for study from onesingle locality. The long series allows an assessment of the variability of the shape of the antennal club. Somespecimens were collected together with the possible host ants Tetramorium sp. and Pheidole sp. (Myrmicinae)
