title: Is ant fauna a good bio-indicator of coastal dune ecosystems in North-East of Algeria?

description: Ants are good bioindicators of habitats and of their quality in many ecosystems. However, their interest in the case of coastal dunes remains to be determined because the environments are instable or subject to strong constraints. The degree of preservation of the Jijel coastal dune system is variable and presents an environmental gradient (sea-land) of five habitats defined by vegetation: upper beach, embryonic, mobile, steady and wooded dune. The aim of the study is to determine if (i) these five habitats have characteristic ant assemblages; (ii) if the variation in ant richness along the gradient shows a continuous increase reflecting very strong disturbances or shows a peak reached before the most stable habitat, therefore at the level of a medium disturbance; and (iii) how environmental factors play on the different ant species. Seventeen stations spread over four sites were selected for the study of myrmecofauna by barber trap, bait, and manual collection, and of vegetation by the quadrats method. Overall, the ant richness profile along the gradient is consistent with an increase towards the most stable environments. The composition of ant communities varies according to habitats and is correlated with the composition of plant communities. The effects on ants of environmental factors deduced from the structure of the vegetation are analysed at the community and species levels. Along the habitat gradient, there is a quadratic relationship between the barycentre and the range of habitat of the species. Despite the small number of species, this group of insects gives interesting results in terms of sensitivity to disturbances.

title: A revision of the <i>Andrena</i> (Hymenoptera: Andrenidae) of Lebanon with the description of six new species

description: Lebanon has a rich but chronically understudied bee fauna. As part of ongoing efforts to better understand bee diversity in Lebanon we present a critical revision of the speciose genus <i>Andrena</i> based primarily on the examination of specimens collected from contemporary surveys, as well as previously undetermined material from museum collections. <i>Andrena</i> (<i>Aciandrena</i>) <i>abruptifovea</i> <b>n. sp</b>. from Lebanon, <i>A</i>. (<i>incertae sedis</i>) <i>cedricola</i> <b>n. sp</b>. from Lebanon and Syria, <i>A</i>. (<i>Euandrena</i>) <i>scrophulariae</i> <b>n. sp</b>. from Lebanon, and <i>A</i>. (<i>incertae sedis</i>) <i>prodigiosa</i> <b>n. sp</b>., from Lebanon, are described. <i>A</i>. (<i>Chlorandrena</i>) <i>edentula</i> <b>n. sp</b>. and <i>A</i>. (<i>Rufandrena</i>) <i>parvispinae</i> <b>n. sp</b>., both from north-western Syria, are described due to their proximity to northern Lebanon. The previously unknown male of <i>A</i>. (<i>Pallandrena</i>) <i>christineae</i> Dubitzky, 2006 is also described. <i>A</i>. (<i>Poliandrena</i>) <i>unifasciata</i> Friese, 1899 <b>stat. rev</b>. which was described from Lebanon is removed from synonymy with <i>A</i>. (<i>Poliandrena</i>) <i>caspica</i> Morawitz, 1886, and the relationship between these two taxa and <i>A</i>. (<i>Poliandrena</i>) <i>unicincta</i> Friese, 1899 is clarified. Altogether, these changes increase the number of <i>Andrena</i> species known from Lebanon to 86, including species known previously only from Turkey or Israel. In total, 25 and 23 species are also reported as newly recorded for Jordan and Syria, respectively. Based on the diversity of <i>Andrena</i> in neighbouring countries in the Levant, it is probable that the true number of <i>Andrena</i> species in Lebanon is well over 100.

title: Non-blue <i>Haslea</i> species (Bacillariophyceae: Naviculaceae) in the benthic marine flora of Guam (Mariana Islands, Western Pacific Ocean).

description: In recent years the taxonomy of <i>Haslea</i> has been in flux. We describe several <i>Haslea</i> taxa from Guam, including four new species, in light of these recent findings. Four delicate, fusiform <i>Haslea</i> species are described from a variety of benthic habitats on coral reefs. These species, <i>H. fusiformis</i> comb. nov. and <i>H. alexanderi, H. apoloniae</i> and <i>H. guahanensis</i> spp. nov. are distinguished by stria density, foramen (‘areola’) shape, and cell size from each other and from similar taxa. A key to all these taxa is provided. In addition, an arcuate species is described as <i>Haslea arculata</i> sp. nov. The presence of a bilayered wall is shown for all these taxa. We compare the morphology of specimens reported as <i>H. howeana</i> from Guam with <i>Navicula tsukamotoi</i>, recently described from Okinawa, and with ‘<i>Navicula</i> cf. <i>howeana</i>’ from Puerto Rico. We provide the first account of the complex cingulum of <i>N. tsukamotoi</i>. We conclude that our specimens match <i>N. tsukamotoi</i> and that <i>H. howeana</i> should be returned to <i>Navicula</i>, but we leave open the question of conspecificity.

title: Consensus and coordination on groups <i>SO</i>(3) and <i>S</i><sup>3</sup> over constant and state-dependent communication graphs

description: We address several problems of coordination and consensus on SO(3) and S3 that can be formulated as minimization problems on these Lie groups. Then, gradient descent methods for minimization of the corresponding functions provide distributed algorithms for coordination and consensus in a multi-agent system. We point out main differences in convergence of algorithms on the two groups. We discuss advantages and effects of representing 3D rotations by quaternions and applications to the coordinated motion in space. In some situations (and depending on the concrete problem and goals) it is advantageous to run algorithms on S3 and map trajectories onto SO(3) via the double cover map S3→SO(3), instead of working directly on SO(3).

title: Early riser or night owl? A flip of a loop can make the difference!. In Art of Science

description: Caption: A conformational switch of the activation loop in Casein Kinase I controls the circadian clock and the duration of the biological day. Participant category: Postdoc Department: Pharmacology Casein Kinase I phosphorylates key regions of a protein called PERIOD, which forms the core of the biological clock in mammals. The figure superimposes two alternative conformations of Casein Kinase I (cyan and magenta). The clock in the figure highlights the region of the kinase whose conformation controls the duration of the biological day. Mutations that favor the "loop up" conformation (in cyan) lead to shortening of the circadian rhythm and emergence of 'early riser' behavior.

title: WhiteHorse Storyboard Painting. In Art of Science

description: Caption: Clam Diggers Working the Great South Bay, Long Island, NY Participant category: Faculty/Scientist Department: Urban Studies and Planning The Great South Bay "StoryBoard Painting" is a form of research communication that sets the stable for discussion about the theory and practice of Bioregionalism. I co-owned and operated the White Horse bay boat featured in the painting foreground with a partner of mine for many years as clam diggers on the Great South Bay (Long Island, NY). My experience on the bay as a workspace fired up my lifelong interest in the use and management of common-pool resources. With conservation practices in place for harvesting clams, the bay kept many people (young and older alike) gainfully employed for decades. Sadly, red tide (suffocating algal blooms) and other forms of ecosystem degradation have decimated the Bay’s clamming industry. The loss is not only economic (loss of jobs), it is also a loss of culture and tradition. A diverse group of concerned citizens, clam diggers, local government agencies, business people, conservationists, and others have been working hard on various restoration initiatives, with mixed results. Some very hopeful signs have been dashed by ongoing red tide events, and the difficulties diverse groups face when trying to collectively establish viable common pool resource management/governance practices). The painting is a storyboard in so far as it provides a visual for celebrating the benefits historically provided by the Bay (clams, healthy livelihood). And it prompts discussion of what it can be in the future if reclaimed --coupling human and natural systems in resource-conserving ways. Note we dug the clams with tongs by hand without large mechanical fossil fuel-driven dredges. This was by design. Digging using human labor power alone is a resource-conserving, regenerative ecosystem approach to harvesting clams. Fossil fuel-powered dredging floods the market with clams, causes prices to drop while damaging the bay bottom and the sustainability of clamming as an industry. The White Horse is long gone now, its old wooden planks part of the earth again –it was built in 1922. In this storyboard painting, the White Horse in the sky symbolizes robust living biopower (horsepower). Humanpower is what clam diggers used to harvest the clams in this period (1970s). Common pool resource conservation by an intentional restriction on the type of power and technology used in harvesting resources is an artform in regulatory innovation. This image celebrates the value of human power as an element in a sustainable and regenerative approach to common-pool resource management.
