Larval host records of butterflies in Japan

Using Japanese literature, we created a consolidated list of host records of butterflies in Japan. The list used the host records described in eight major illustrated reference books, two checklists, and 14 other pieces of literature. The presence of larvae on plants, the observation of larvae eating plants or insects in the field were considered as host records. We collected all species recorded in Japan. Scientific, family, and Japanese names of butterflies were consolidated using the BINRAN database (http://binran.lepimages.jp/). Scientific and Japanese names of host plants were based on the YList database (http://ylist.info/). If scientific names of host plants were not found in YList, we used scientific names based on The Plant List (http://www.theplantlist.org/). Family names of host plants were based on the Catalogue of Life database (http://www.catalogueoflife.org/). Scientific, family, and Japanese names of host insects were based on the MOKUROKU database (http://konchudb.agr.agr.kyushu-u.ac.jp/mokuroku/) for Hymenoptera and the catalogue of the Paraneoptera of Japan published by the Entomological Society of Japan for Hemiptera. We also provided the references of each host record and the original names described in the referred literature. Two datasets, HostDB and ReferenceDB, were created to include 3600 records of butterfly larval hosts in Japan, along with scientific and Japanese names of each species and a literature list. These datasets will be useful for basic and applied biological studies of butterflies. Data files are stored in the Ecological Research Data Archives (http://db.cger.nies.go.jp/JaLTER/ER_DataPapers/) and available from http://hostbj.lepumus.net/.

Interspecific responses of wild African carnivores to odour of 3-mercapto-3-methylbutanol,a component of wildcat and leopard urine

The scent of 3-mercapto-3-methylbutanol (3-M-3-MB), a volatile component of leopard (Panthera pardus) and domestic cat (Felis silvestris catus) urine, released at about 10 ng/s from slow-release dispensers, elicited scent-marking from African civet (Civettictis civetta), small-spotted genet (Genetta genetta) and slender mongoose (Galerella sanguinea), as well as African wildcat (F. s. cafra). A female leopard was apparently repelled by the scent. The scent-marking and scent-rubbing by species other than African wildcats and leopards were unexpected and have important implications for the design of studies to investigate chemical communication between wild mammals and the use of camera traps to estimate animal numbers. Videos showing the behaviours referred to in this article are available at; http://www.momo-p.com/showdetail-e.php?movieid=momo161223fs01a; http://www.momo-p.com/showdetail-e.php?movieid=momo161223gs01a; http://www.momo-p.com/showdetail-e.php?movieid=momo161223gg01a.     

Paternal care behaviors of Japanese giant salamander <Emphasis Type="Italic">Andrias japonicus</Emphasis> in natural populations

Parental care among salamanders is typically provided by females. A rare case of parental care by male salamanders appears to occur in Cryptobranchidae. Yet, paternal behaviors have rarely been reported from natural populations of any Cryptobranchid salamanders, and their adaptive significance is poorly understood. The present study aimed to examine paternal care behaviors in a fully aquatic Japanese giant salamander (Andrias japonicus) in situ. At the beginning of the summer breeding season, large males, called den-masters, occupy burrows along stream banks for breeding and nesting. We videotaped post-breeding behaviors of two den-masters that stayed with the eggs, one in a natural and the other in an artificial nest in natural streams. We identified three behaviors, tail fanning, agitating and egg eating, to be parental care. Tail fanning provides oxygenated water for the eggs. We found that the den-master in the artificial nest, where dissolved oxygen level was lower, displayed tail fanning more frequently. Agitating the eggs with its head and body likely prevents yolk adhesions. The den-masters selectively ate whiter eggs that appeared to be dead or infected with water mold. This behavior, which we termed hygienic filial cannibalism, likely prevents water mold from spreading over healthy eggs.

The scent of your enemy is my friend? The acquisition of large carnivore scent by a smaller carnivore

Scent marking is critical to intraspecific communication in many mammal species, but little is known regarding its role in communication among different species. We used 4 years of motion-triggered video to document the use of scent marking areas—termed “community scrapes”—by pumas (Puma concolor) (http://www.momo-p.com/showdetail-e.php?movieid=momo160812pc01a) and other carnivore species. We found that gray foxes (Urocyon cinereoargenteus) routinely rubbed their cheeks on puma scrapes (http://www.momo-p.com/showdetail-e.php?movieid=momo160812uc01a), and tested a series of hypotheses to determine its function. We found that gray foxes selected puma scrapes over other objects, and cheek rubbing by foxes was also correlated with how recently a puma had visited the scrape, suggesting that foxes were intent upon accumulating fresh puma scent. Cheek rubbing by foxes was not correlated with their breeding season or with how recently another fox had visited the site. Finally we found a cascading pattern in the occurrence of pumas, coyotes (Canis latrans) and gray foxes at community scrapes, suggesting that gray foxes may use puma scent to deter predation. This is the first published study to find evidence of a subordinate species using the scent of a dominant species to communicate with heterospecifics. The behavioral cascade we found in scent marking patterns also suggests that scent marking could be a mechanism that impacts the distribution and abundance of species.

Mating and aggressive behaviour of <Emphasis Type="Italic">Brachyrhaphis olomina</Emphasis> (Cyprinodontiformes: Poeciliidae)

Despite the increasing interest in the use of intromittent male genitalia and coercive mating behaviour in poeciliids, detailed studies of the mating behaviour of most species in this family are lacking. We describe here the mating and aggressive behaviours of Brachyrhaphis olomina, and correlate them with the condition of the female’s ovum and embryos (immature, mature and pregnant). B. olomina performed a wide range of aggressive (sidle spread, tail beating, coordinate) and mating behaviours (approximation, touch, lateral display, touch-lateral display). Some behaviours (e.g. tail beating) are shared with other poeciliids, but two sexual behaviours (touch and lateral display) and one aggressive (coordinate) behaviour may be unique to B. olomina and were not reported in a previous study. Differences in male behaviour when paired with a female with mature ovum (more mating displays, no agonistic movements) suggest that males detect the female’s reproductive condition from some distance. The distinctive nature of mating behaviour in B. olomina highlights the importance of studying different species to have a better understanding of the evolution of mating and aggressive behaviours in poeciliids.

On May 11th and 12th 2017 was held in Nantes, France, the international meeting “Advances in transgenic animal models and techniques” (http://www.trm.univ-nantes.fr/). This biennial meeting is the fifth one of its kind to be organized by the Transgenic Rats ImmunoPhenomic (TRIP) Nantes facility (http://www.tgr.nantes.inserm.fr/). The meeting was supported by private companies (SONIDEL, Scionics computer innovation, New England Biolabs, MERCK, genOway, Journal Disease Models and Mechanisms) and by public institutions (International Society for Transgenic Technology, University of Nantes, INSERM UMR 1064, SFR François Bonamy, CNRS, Région Pays de la Loire, Biogenouest, TEFOR infrastructure, ITUN, IHU-CESTI and DHU-Oncogeffe and Labex IGO). Around 100 participants, from France but also from different European countries, Japan and USA, attended the meeting.     

Metabolic syndrome is associated to high-sensitivity cardiac troponin T elevation

Introduction: Metabolic syndrome (MetS) and high-sensitivity cardiac troponin T (hs-TnT) are associated with higher risk for cardiovascular diseases (CVD). Our aim was to assess the relation between hs-TnT elevation and MetS in a general population sample.

Materials and methods: Individuals participating in an annual health survey program between 2010 and 2016 were included in the study. Blood samples including hs-TnT levels were collected. The study population was divided into three groups based on hs-TnT levels – undetectable (<5?ng/L), intermediate (5–14?ng/L) and elevated (>14?ng/L).

Results: A total of 5994 subjects were included in the study, the mean age was 48.5 and 4336 (72%) were males. Compared with subjects with undetectable hs-TnT the prevalence of MetS was higher in those with detectable and elevated levels – 392 (10%) vs. 270 (15%) and 51 (33%), respectively (p?<?0.001). In a multivariate model adjusted for age, gender and multiple co-morbidities, the number of MetS components and presence of MetS were significantly associated with an increased risk for detectable hs-TnT levels (OR?=?1.02 {for each component}; 95% CI [1.00–1.05], p?=?0.04) and (OR?=?1.13; 95% CI [1.07–1.2], p?<?0.001) respectively. Only the waist, glucose and hypertension components of the MetS were significantly associated with elevated troponin.

Conclusions: The MetS and its distinct components have a cumulative impact on hs-TnT levels in apparently healthy subjects.     

The Year of the Wisent

Delving into European prehistory, two recent studies analyze ancient DNA from bison species depicted by our ancestors on the walls of their caves. The DNA tells a story of migrations driven by climate change but leaves some mystery clouding the genetic descent and climate preference of the still-extant wisent, otherwise known as the European bison.See research articles: https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-016-0317-7 http://www.nature.com/articles/ncomms13158     

Comet assay for assessment of DNA damage in greenhouse workers exposed to pesticides

Purpose: The main goal of the present study was to determine DNA damage in pesticide-exposed greenhouse workers and pesticides non-exposed controls.

Materials and methods: The DNA damage was measured by alkaline comet assay method (pH?>?13) in 41 greenhouse workers and 45 non-exposed individuals as the control. Pesticide exposure was assessed by duration of working in the greenhouse and pesticide application in the greenhouse time. DNA damage was estimated by arbitrary unit and damage frequency.

Results: Arbitrary unit and damage frequency were consistently significantly higher in greenhouse workers than those of the controls (p?=?0.001). In terms of gender in greenhouse, DNA damage of female workers was significantly higher than those in male workers (p?<?0.05). We found significant correlation between DNA damage and working hours spent. Multiple linear regression analysis showed that working hours in the greenhouse as an indication of pesticide exposure were significantly associated with the DNA damage, which can be attributed to the genotoxic potential of the pesticide mixture.

Conclusions: The comet assay is sensitive to detect the damage exposed to chronic effect of pesticides in greenhouse workers. Significant DNA damage was obtained for the exposed group, which was associated with the pesticide exposure.

Assessment of Effects of Human Development on the Environment by Using System Dynamic Modeling Technique (SD): A Case Study of the Mkomazi Watershed (Pangani Basin) in Northeastern Tanzania

This study analyzes land use changes due to human development in the Mkomazi Valley, Tanzania, and its impacts on nature using the SD–Modeling (System Dynamic modeling) technique. Ultimately this method relates environment and economy of society with regard to a seasonal rainfall–based agriculture practice and their harmonization with irrigation agriculture for development sustainability. VENSIM PLE (VENTANA SIMULATION ENVIRONMENT, PERSONAL LEARNING EDITION 2002 VENSIM PLE (VENTANA SIMULATION ENVIRONMENT PERSONAL LEARNING EDITION), 2002, Vensim Product Center,Ventana Systems Inc URL:http://www.vensim.com, E-mail: plesupport@vensim.com  [Google Scholar]) software, which simplified the assessment, was used to build a SD–model that accommodated changes in Population, Deforestation, Gross Domestic Product (GDP), and Basin Storage. Model results indicate groundwater behavior, deforestation, public opinion and decreased health of the farmers all relate to changes in land use (i.e., introduction of a rice development project) with its associated environment degradation, deforestation, and poverty due to deforestation. Moreover, these changes might be the cause of animal flight from the Mkomazi game reserve and an increase in human disease and deaths. Finally, it is concluded that uncontrolled human activities and behavior are the main causes of environmental degradation and therefore a brief summary is presented on challenges and opportunities for decision–makers on the sustainable development of the Mkomazi Valley.

Description of the first endemic earthworm species from Cyprus (Oligochaeta: Lumbricidae)

New earthworm samples from Cyprus are assessed and discussed. A re-evaluation of specimens previously relegated to the Southern Alpine species Perelia nematogena (Rosa, 1903), revealed two independent species: Perelia phoebea (Cognetti, 1913 Cognetti, L. (1913): Escursioni zoologiche del Dr. E. Festa nell’Isola di Rodi V. Oligocheti. Bollettino dei Musei di zoologia ed anatomia comparata della R. Università di Torino, 28, 1–6. [Google Scholar]) ,described originally from Rhodes Island, (Greece) and an undescribed species Perelia makrisi sp. n. The new species is similar also to the Levantine Pe. galileana Csuzdi &; Pavlí?ek, 2005 and corroborates the hypotheses that the autochthonous earthworm fauna of Cyprus is of Levantine origin.

Ergothioneine production with Aspergillus oryzae

To establish a reliable and practical ergothioneine (ERG) supply, we employed fermentative ERG production using Aspergillus oryzae, a fungus used for food production. We heterologously overexpressed the egt-1 and -2 genes of Neurospora crassa in A. oryzae and succeeded in producing ERG (231.0 mg/kg of media, which was 20 times higher than the wild type).

The FOCUS,AFFINITY and EFFECTS trials studying the effect(s) of fluoxetine in patients with a recent stroke: statistical and health economic analysis plan for the trials and for the individual patient data meta-analysis

Background

Small trials have suggested that fluoxetine may improve neurological recovery from stroke. FOCUS, AFFINITY and EFFECTS are a family of investigator-led, multicentre, parallel group, randomised, placebo-controlled trials which aim to determine whether the routine administration of fluoxetine (20 mg daily) for six months after an acute stroke improves patients’ functional outcome.

Methods/Design

The core protocol for the three trials has been published (Mead et al., Trials 20:369, 2015). The trials include patients aged 18 years and older with a clinical diagnosis of stroke and persisting focal neurological deficits at randomisation 2–15 days after stroke onset. Patients are randomised centrally via each trials’ web-based randomisation system using a common minimisation algorithm. Patients are allocated fluoxetine 20 mg once daily or matching placebo capsules for six months. The primary outcome measure is the modified Rankin scale (mRS) at six months. Secondary outcomes include: living circumstances; the Stroke Impact Scale; EuroQol (EQ5D-5 L); the vitality subscale of the 36-Item Short Form Health Survey (SF36); diagnosis of depression; adherence to medication; serious adverse events including death and recurrent stroke; and resource use at six and 12 months and the mRS at 12 months.

Discussion

Minor variations have been tailored to the national setting in the UK (FOCUS), Australia, New Zealand and Vietnam (AFFINITY) and Sweden (EFFECTS). Each trial is run and funded independently and will report its own results. A prospectively planned individual patient data meta-analysis of all three trials will provide the most precise estimate of the overall effect and establish whether any effects differ between trials or subgroups. This statistical analysis plan describes the core analyses for all three trials and that for the individual patient data meta-analysis. Recruitment and follow-up in the FOCUS trial is expected to be completed by the end of 2018. AFFINITY and EFFECTS are likely to complete follow-up in 2020.

Indoor Air as a Source of VOC Contamination in Shallow Soils Below Buildings

US EPA and many state regulatory agency guidance documents recommend below-foundation vapor sampling as a key element of site investigations to determine if vapor migration from underlying soil into buildings is a completed exposure pathway (USEPA, 2002 US EPA (U.S. Environmental Protection Agency). Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance). November2002.  [Google Scholar]; WIDHFS, 2003 WIDHFS (Wisconsin Department of Health and Family Services). Chemical Vapor Intrusion and Residential Indoor Air, Guidance for Environmental Consultants and Contractors. June202004. Available at http://dhfs.wisconsin.gov/eh/Air/fs/VI_prof.htm (accessed) [Google Scholar]; San Diego County, 2004 San Diego County Department of Environmental Health. Site Assessment and Mitigation (SAM) Manual. June202004. http://www.sdcounty.ca.gov/deh/lwq/sam/vapor_risk_assessment_2000.html (accessed) [Google Scholar]; PADEP, 2004 PADEP (Pennsylvania Department of Environmental Protection). Land Recycling Program Technical Guidance Manual-Section IV.A.4. June202004. Vapor Intrusion into Buildings from Groundwater and Soil under Act 2 Statewide Health Standard. Document Number 253-0300-100. http://www.dep.state.pa.us/eps/default.asp (accessed) [Google Scholar]). If volatile organic compounds (VOCs) are detected below the building foundation, then VOC migration from the subsurface is assumed to be occurring, and further investigation is needed to determine the extent of the VOC impact. These guidance documents are predicated on the assumption that VOCs detected in below-foundation samples have originated from deeper within the subsurface. However, detection of VOCs in below-foundation vapor samples alone is not sufficient to conclude that the VOCs are migrating from the subsurface upward towards a building. VOCs detected in below-foundation vapor samples can originate from indoor sources, migrating down through the slab by diffusion or advection. Commonly referenced conceptual models for vapor intrusion address VOC migration from the subsurface into buildings but do not consider the potential for VOC migration from buildings into the subsurface (USEPA, 2002 US EPA (U.S. Environmental Protection Agency). Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance). November2002.  [Google Scholar]; Johnson and Ettinger, 1991 Johnson, P. C. and Ettinger, R. A. 1991. Heuristic model for the intrusion rate of contaminant vapors into buildings. Environ. Sci. Technol., 25(8): 1445–1452. [CSA][CROSSREF][Crossref], [Web of Science ®] [Google Scholar]; Parker, 2003 Parker, J. C. 2003. Modeling volatile chemical transport, biodecay, and emission to indoor air. Ground Water Mon. Remed., 23(1): 107–120. [CSA][Crossref], [Web of Science ®] [Google Scholar]). The advective and diffusive forces that lead to the migration of VOCs from the subsurface into buildings are equally likely to result in the migration of VOCs from buildings into the subsurface when pressure or concentration gradients support such migration. In this paper we present: i) pressure gradient measurements indicating bi-directional advective flow across building foundations, ii) simple modeling indicating that indoor sources of VOCs may cause subsurface impacts through advection across the building foundation, and iii) field data from a site where indoor sources rather than subsurface contamination were the source of VOCs detected in below-foundation vapor samples.
