Harden up: metal acquisition in the weaponized ovipositors of aculeate hymenopteraBaumann, Kate Vicenzi, Edward P. Lam, Thomas Douglas, Janet Arbuckle, Kevin Cribb, Bronwen Brady, Seán G. Fry, Bryan G.2018DOI: info:10.1007/s00435-018-0403-1Zoomorphology1181-180720-213X

Abstract: The use of metal ions to harden the tips and edges of ovipositors is known to occur in many hymenopteran species. However, species using the ovipositor for delivery of venom, which occurs in the aculeate hymenoptera (stinging wasps, ants, and bees) remains uninvestigated. In this study, scanning electron microscopy coupled with energy-dispersive X-ray analysis was used to investigate the morphology and metal compositional differences among aculeate aculei. We show that aculeate aculei have a wide diversity of morphological adaptations relating to their lifestyle. We also demonstrate that metals are present in the aculei of all families of aculeate studied. The presence of metals is non-uniform and concentrated in the distal region of the stinger, especially along the longitudinal edges. This study is the first comparative investigation to document metal accumulation in aculeate aculei.

Abstract: Amphipods constitute an abundant part of Icelandic deep-sea zoobenthos yet knowledge of the diversity of this fauna, particularly at the molecular level, is scarce. The present work aims to use molecular methods to investigate genetic variation of the Amphipoda sampled during two IceAGE collecting expeditions. The mitochondrial cytochrome oxidase subunit 1 (COI) of 167 individuals originally assigned to 75 morphospecies was analysed. These targeted morhospecies were readily identifiable by experts using light microscopy and representative of families where there is current ongoing taxonomic research. The study resulted in 81 Barcode Identity Numbers (BINs) (of which >90% were published for the first time), while Automatic Barcode Gap Discovery revealed the existence of 78 to 83 Molecular Operational Taxonomic Units (MOTUs). Six nominal species (Rhachotropis helleri, Arrhis phyllonyx, Deflexilodes tenuirostratus, Paroediceros propinquus, Metopa boeckii, Astyra abyssi) appeared to have a molecular variation higher than the 0.03 threshold of both p-distance and K2P usually used for amphipod species delineation. Conversely, two Oedicerotidae regarded as separate morphospecies clustered together with divergences in the order of intraspecific variation. The incongruence between the BINs associated with presently identified species and the publicly available data of the same taxa was observed in case of Paramphithoe hystrix and Amphilochus manudens. The findings from this research project highlight the necessity of supporting molecular studies with thorough morphology species analyses.

Abstract: The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into the relationships of North East Atlantic Rhachotropis. The 31 cytochrome oxidase subunit I (COI) sequences generated for this study were assigned 13 Barcode Index Numbers (BINs) in the Barcode of Life database (BOLD), of which 12 are new to the database. Molecular analyses of COI and 16S sequences could not confirm a theory that depth has a greater influence on the phylogeny of Rhachotropis than geographic distance. Although the North East Atlantic is a well-studied area, our molecular investigations revealed the genus Rhachotropis may contain cryptic species, which indicates a higher biodiversity than currently known. For example, the specimens which key to Rhachotropis helleri is a complex of three COI clades, two of which cannot be identified with morphological traits. One specimen of each of the clades in the cladogram was documented by high definition photographs. A special focus was on the visual morphology of the eyes, as this character shows interspecific differences within the genus Rhachotropis in response to fixation in ethanol. Detailed morphological investigation showed that some clades thought to be indistinguishable can be separated by minute but consistent morphological characters. Datamining Genbank to examine all registered COI-sequences of R. aculeata, the only previously known Rhachotropis BIN in the North Atlantic and sub-Arctic, showed R. aculeata to be subdivided by an Arctic and a North Atlantic population.

Between 2012 and 2017, we recorded four additional Dermacentor species from this country: D. bellulus (Schulze, 1935); D. compactus Neumann, 1901; D. filippovae Apanaskevich & Apanaskevich, 2015; and D. tamokensisApanaskevich & Apanaskevich, 2016. In addition, seven specimens in the tick collection at the Institut Pasteur du Laos may represent new species and are currently under taxonomic investigation.

Abstract: Increasingly, museums are installing energy-saving light sources, such as LED (light emitting diode) lamps. LEDs represent an evolving technology; there are concerns about the effects of light spectra on artifacts, including textiles. Many LED models do not possess the same color rendering properties that observers are accustomed to, and it is important to understand the effects that spectra can play on dyed textiles. This research focuses on the visual effects of different light spectra, including those of LEDs, on textile colorants in order to gauge the range of color differences produced. Nine early synthetic dyes and one commercial fading standard were utilized. This paper summarizes our findings to date: that LED spectra with the same color temperature can render very different observable colors, especially with saturated colors. Saturated purples were found to be extremely hard to render accurately with LEDs. Other hues may also be compromised. Experimental work indicates that color temperature, illuminance level, and the commercial Color Rendering Index (CRI) are insufficient specifications for exhibitions LED light sources. An instrumental method for assessing LEDs before exhibition installation is suggested.
