title: Adaptive signaling behavior in stomatopods under varying light conditions

description: Stomatopod crustaceans (mantis shrimp) are aggressive benthic marine predators with extraordinary color vision. When communicating with conspecifics, many stomatopods display conspicuously colored body areas, often in combination with other types of signals such as motion and chemical cues. Some species occupy wide depth ranges (&gt;30 m), where changing light conditions can influence color perception. To test the potential effects of differing ambient lights on signaling behavior, stomatopods (<i>Gonodactylus smithii</i>) interacted with conspecifics in aquaria, under full-spectrum, high intensity light or light restricted in either spectrum or intensity. During intrasexual and intersexual trials in full-spectrum, high intensity light, animals performed more aggressive acts using colored body parts (meral spread, lunge, strike). Stomatopods used significantly more antennular flicking, and performed aggressive acts at reduced distances under restricted light conditions. To compare the use of antennules in visual and chemical communication, additional experiments showed more antennular flicking in response to chemical stimuli from food or conspecifics compared to seawater controls. This response ceased immediately after ablation of antennular chemoreceptors but returned to pre-treatment levels after 5 days of recovery. These findings suggest that stomatopods can vary their use of signals during conspecific interactions under different photic conditions. These inducible, plastic behavioral responses can potentially improve signal transfer in varying light environments.

title: Cope's rule in the Ordovician trilobite family Asaphidae (order Asaphida): patterns across multiple most parsimonious trees

description: Cope's rule defines lineages that trend towards an increase in body size through geological time. The trilobite family Asaphidae is one of the most diverse of the class Trilobita and ranges from the Upper Cambrian through to the Upper Ordovician. The group is one trilobite clades that displays a large size range and contains several of the largest trilobite species. Reduced major axis correlations between the lengths of cephala and pygidia and the total sagittal length of complete individuals have high support and were used to standardise all incomplete specimens to total axial length. Phylogenetic studies into Cope's rule tend to use supertrees, composite trees or a single tree selected through a fit criterion. Here, for the first time, all trees recovered from a maximum parsimony analysis were analysed equally. Maximum likelihood was used to fit four evolutionary models: random walk, directional, Ornstein–Uhlenbeck (evolution towards an adaptive optimum) and stasis. These were compared equally using Akaike weights. Fitting of evolutionary models by maximum likelihood supports stasis as consistently the most likely model across all trees with low support for directionality.

title: A new basal rebbachisaurid (Sauropoda, Diplodocoidea) from the Early Cretaceous of the Neuquén Basin; evolution and biogeography of the group

description: Despite that the origin of rebbachisaurids is retrieved as Late Jurassic is not until the upper Lower Cretaceous that this group can be recognised in the fossil record. The group is geographically restricted to Gondwana and Europe, and is particularly diverse in the lower Upper Cretaceous of South America. In this subcontinent, Early Cretaceous forms are solely represented by <i>Amazonsaurus</i> and <i>Zapalasaurus</i>, being the former the putative basalmost rebbachisaurid known. Here, we provide a revised description of the sauropod from the Lohan Cura Formation (Aptian–Albian) that was previously identified as <i>Limaysaurus</i> sp. The new information available (mainly based on new elements) allows us to recognise a new taxon, <i>Comahuesaurus windhauseni</i> gen. et sp. nov. The phylogenetic analysis carried out retrieved this taxon as a relatively basal form of rebbachisaurid, well separated from Limaysaurinae. In this phylogenetic context, the new taxon revealed the presence of a reduced hyposphene–hypantrum system in rebbachisaurids more derived than <i>Histriasaurus</i>, which is completely lost only in Limaysaurinae. Finally, a biogeographical scenario for rebbachisaurids is analysed through the use of a Dispersal, Extinction and Cladogenesis analysis, which retrieves a South American origin for this linage, and a fast dispersion to Africa and Europe during the Hauterivian–Barremian.

title: Reproduction of the invasive fan worm <i>Branchiomma bairdi</i> (Polychaeta: Sabellidae)

description: The fan worm <i>Branchiomma bairdi</i> has been introduced to the Gulf of California from its original distribution in the Caribbean Sea, and is now a conspicuous component of most benthic communities. Study of reproductive features is essential to understand the dispersion capability of <i>B. bairdi</i> and its invasive potential. Sampling was carried out monthly in the port of Mazatlán during 2009 (23°12′13′′N, 106°24′31.4′′W). Abundance and biomass were measured. Sex and maturity were determined. Gametogenesis and observations on the spawning, fertilization, larval development and brooding are presented. The highest values of abundance (&gt;2500 worms m<sup>−2</sup>) and biomass (175 g m<sup>−2</sup>) occurred during August and September. Mature simultaneous hermaphrodite worms were found continuously throughout the annual cycle as well as asexual forms. In <i>B. bairdi</i> gametogenesis is extra-ovarian. Three posterior thoracic segments and all abdominal segments are involved in the production of gametes. Sperm are ect-aquasperm type (free spawners with external fertilization). Spermatids are grouped in tetrads. Ovules are retained for intra-tubular fertilization. Larval development is lecithotrophic. Embryos are brooded on the collar and branchial crown.

title: Is the Bosphorus Strait a barrier to gene flow for the Mediterranean mussel, <i>Mytilus galloprovincialis</i> (Lamarck, 1819)?

description: The Mediterranean mussel, <i>Mytilus galloprovincialis</i>, is a commercially important species with a continuous distribution spanning the eastern Atlantic, the Mediterranean, the Aegean and the Black Sea. Previous genetic research has indicated differentiation between the Aegean and the Ukrainian Black Sea populations of this species. Using the COIII region of mitochondrial DNA and six microsatellite markers, we investigated whether there is any genetic differentiation among populations of the Black Sea, the Bosphorus Strait and the Sea of Marmara, on a local scale. A total of 170 mussels representing eight localities extending from the Black Sea to the Sea of Marmara, including the Bosphorus Strait, were analysed. Results for mitochondrial DNA and microsatellite analysis showed no significant genetic grouping among geographical regions. Ukrainian samples differed from those analysed in this study by a single base position. These results suggest that the Bosphorus Strait does not restrict gene flow for this species. Analysis of samples from a greater geographic range, encompassing the Dardanelles, the Aegean, and more northern populations in the Black Sea, will be necessary to understand the nature of the previously reported genetic break of the Mediterranean mussels between the Black Sea and the Aegean.

title: Fouling of nanostructured insect cuticle: adhesion of natural and artificial contaminants

description: The adhesional properties of contaminating particles of scales of various lengths were investigated for a wide range of micro- and nanostructured insect wing cuticles. The contaminating particles consisted of artificial hydrophilic (silica) and spherical hydrophobic (C<sub>18</sub>) particles, and natural pollen grains. Insect wing cuticle architectures with an open micro-/nanostructure framework demonstrated topographies for minimising solid–solid and solid–liquid contact areas. Such structuring of the wing membranes allows for a variety of removal mechanisms to contend with particle contact, such as wind and self-cleaning droplet interactions. Cuticles exhibiting high contact angles showed considerably lower particle adhesional forces than more hydrophilic insect surfaces. Values as low as 3 nN were recorded in air for silica of ∼28 nm in diameter and &lt;25 nN for silica particles 30 μm in diameter. A similar adhesional trend was also observed for contact with pollen particles.

title: Traditional Chinese medicine as dual guardians against hypertension and cancer?

description: This study utilizes the comprehensive traditional Chinese medicine database TCM Database@Taiwan (http://tcm.cmu.edu.tw/) in conjunction with structure-based and ligand-based drug design to identify multi-function Src inhibitors. The three potential TCM candidates identified as having suitable docking conformations and bioactivity profiles were Angeliferulate, (3R)-2′-hydroxy-3′,4′-dimethoxyisoflavan-7-O-beta-D-glucoside (HMID), and 3-[2′,6-dihydroxy-5′-(2-propenyl)[1,1′-biphenyl]3-yl]-(E)-2-propenoic acid (3PA). Molecular dynamics simulation demonstrated that the TCM candidates have more stable interactions with the cleft and in complex with Src kinase compared to Saracatinib. Angeliferulate and HMID, both originated from <i>Angelica sinensis</i>, not only interact with Lys298 and amino acids from different loops in the cleft, but also with Asp407 located on the activation loop. These interactions are important to reduce the opening of the activation loop due to phosphorylation, hence stabilize the Src kinase cleft structure and inhibit activation. The TCM candidates also exhibited high affinity to other cancer-related target proteins (EGFR, HER2, and HSP90). Our observations suggest that the TCM candidates might have multi-targeting effects in hypertension and cancer.

title: The <i>Quercus cerris</i> woods of the alliance <i>Carpinion orientalis</i> Horvat 1958 in Italy

description: A phytosociological study of the alliance <i>Carpinion orientalis</i> in the hilly and subcoastal areas of the Italian peninsula is presented. These woods are included in the suballiances <i>Laburno-Ostryenion</i> and <i>Lauro-Quercenion</i>; the distinction between these two suballiances is not always easy also because of the conservation status of these forest ecosystems. The hilly and subcoastal Turkey oak woods of the alliance <i>Carpinion orientalis</i> are mainly distributed on the Adriatic side of the Italian peninsula, where they are found on neutro-basic substrata to which these coenoses are linked. The Turkey oak woods of the alliance <i>Teucrio siculi-Quercion cerridis</i> are strongly linked to the acidic substrata typical of the Tyrrhenian side, but are sporadically found on the Adriatic side within small enclaves with more acidic substrata. A numerical analysis allowed us to rearrange the lower hierarchical levels of the associations of Turkey oak woods of the alliance <i>Carpinion orientalis</i>. In particular, the association <i>Lonicero xylostei-Quercetum cerridis</i> is included in the alliance <i>Carpinion orientalis</i>, and the new subassociation <i>festucetosum exaltatae</i> is proposed. The subassociation <i>rosetosum arvensis</i> is proposed for the association <i>Daphno laureolae-Quercetum cerridis</i>, and the new subassociation <i>cytisophylletosum sessilifolii</i> of the association <i>Aceri obtusati-Quercetum cerridis</i> is described.
