The fast-running flies (Diptera, Hybotidae, Tachydromiinae) of Singapore and adjacent regions

This is the first comprehensive introduction to the flies of the subfamily Tachydromiinae (Hybotidae) of Singapore. The monograph summarizes all publications on the Tachydromiinae of Singapore and includes new data resulting from mass-trapping surveys made in Singapore during the last six years. A few samples from Malaysia (Johor province, Pulau Tioman and Langkawi) have been also included in this study. In Singapore the Tachydromiinae are the most diverse group of Empidoidea (except Dolichopodidae) and currently comprise 85 species belonging to the following nine genera: Platypalpus (1), Tachydromia (1), Chersodromia (6), Pontodromia (1), Drapetis (5), Elaphropeza (60), Crossopalpus (1), Nanodromia (3) and Stilpon (7). All species are diagnosed and illustrated. The following 28 species are described as new for science: Chersodromia bulohensis sp. nov. (Singapore), C. glandula sp. nov. (Singapore, Malaysia), C. malaysiana sp. nov. (Singapore, Malaysia), C. pasir sp. nov. (Malaysia), C. sylvicola sp. nov. (Singapore), C. tiomanensis sp. nov. (Malaysia), Crossopalpus temasek sp. nov. (Singapore), Drapetis bakau sp. nov. (Singapore, Malaysia), D. hutan sp. nov. (Singapore), D. laut sp. nov. (Singapore, Malaysia), D. mandai sp. nov. (Singapore), D. pantai sp. nov. (Singapore, Malaysia), Elaphropeza chanae sp. nov. (Singapore), E. collini sp. nov. (Singapore), E. gohae sp. nov. (Singapore), E. kranjiensis sp. nov. (Singapore), E. lowi sp. nov. (Singapore), E. semakau sp. nov. (Singapore), E. shufenae sp. nov. (Singapore), Nanodromia hutan sp. nov. (Singapore), N. spinulosa sp. nov. (Singapore), Platypalpus singaporensis sp. nov. (Singapore), Pontodromia pantai sp. nov. (Singapore), Stilpon arcuatum sp. nov. (Singapore), S. neesoonensis sp. nov. (Singapore), S. nigripennis sp. nov. (Singapore), S. singaporensis sp. nov. (Singapore), S. weilingae sp. nov. (Singapore). A redescription is given for Crossopalpus exul (Osten-Sacken, 1882) (Taiwan). Males of Elaphropeza feminata Shamshev & Grootaert, 2007 and E. modesta Shamshev & Grootaert, 2007 as well as females of Elaphropeza ubinensis Shamshev & Grootaert, 2007 and Nanodromia narmkroi Grootaert & Shamshev, 2003 are described for the first time. Keys to genera and species, which are generally applicable to the whole of Southeast Asia, are compiled. An analysis of the species ecological preferenda is presented

Rice pathogens intercepted on seeds originating from 11 African countries and from the USA

1,916 rice seed samples from 11 African countries and the USA were tested for the presence of pathogenic microorganisms or those affecting seed quality. Bacillus spp., Pantoea spp., Sphingomonas sp. and the fungi Acremoniella sp., Alternaria sp., Aspergillus flavus, A. fumigatus, A. niger, Chaetomium sp., Curvularia sp., Fusarium oxysporum, F. solani, Fusarium sp., Helminthosporium sp., Microdochium oryzae, Nigrospora oryzae, Penicillium sp., Pestalotia sp., Phoma sp., Magnaporthe oryzae, Rhizopus sp., Sarocladium sp. and Tilletia barclayana were isolated. The highest incidence values were obtained with Curvularia sp., Microdochium oryzae, A. flavus, F. solani and Nigropora sp. In contrast, these fungi were not isolated from seeds of many countries with Togo having the least affected seeds (nine out of the 24 potential organisms diagnosed). The highest frequencies of these organisms were found on seed samples from Benin (20/22), Burundi and Tanzania (19/24), and Senegal (18/24). Across countries, A. flavus, A. fumigatus, Curvularia sp., F. solani, Nigropora sp., Rhizopus sp. and Microdochium oryzae were the most frequently isolated organisms. Concerning the major diseases, blast was diagnosed only once despite the high number of samples tested

Ichneumonid wasps from Madagascar. VI. The genus Pristomerus (Hymenoptera: Ichneumonidae: Cremastinae)

Pristomerus species of Madagascar are revised. We report 15 species, of which 12 are newly described: P. guinness sp. nov., P. hansoni sp. nov., P. kelikely sp. nov., P. keyka sp. nov., P. moramora sp. nov., P. melissa sp. nov., P. patator sp. nov., P. ranomafana sp. nov., P. roberti sp. nov., P. vahaza sp. nov., P. veloma sp. nov. and P. yago sp. nov. Pristomerus albescens (Morley) and P. cunctator Tosquinet are newly recorded from Madagascar and new host and/or distribution records are provided for this species. A dichotomous key to all species is provided. The zoogeographical relation of the Malagasy fauna of Pristomerus with respect to mainland Africa is discussed: only three of the 15 species are reported to occur outside of Madagascar, suggesting a high level of endemism in Madagascar which was not unexpected

Symplectically-invariant soliton equations from non-stretching geometric curve flows

A moving frame formulation of geometric non-stretching flows of curves in the Riemannian symmetric spaces $Sp(n+1)/Sp(1)\times Sp(n)$ and $SU(2n)/Sp(n)$ is used to derive two bi-Hamiltonian hierarchies of symplectically-invariant soliton equations. As main results, multi-component versions of the sine-Gordon (SG) equation and the modified Korteweg-de Vries (mKdV) equation exhibiting $Sp(1)\times Sp(n-1)$ invariance are obtained along with their bi-Hamiltonian integrability structure consisting of a shared hierarchy of symmetries and conservation laws generated by a hereditary recursion operator. The corresponding geometric curve flows in $Sp(n+1)/Sp(1)\times Sp(n)$ and $SU(2n)/Sp(n)$ are shown to be described by a non-stretching wave map and a mKdV analog of a non-stretching Schr\"odinger map.Comment: 39 pages; remarks added on algebraic aspects of the moving frame used in the constructio

Examining the influence of cell size and bandwidth size on kernel density estimation crime hotspot maps for predicting spatial patterns of crime

Hotspot mapping is a popular technique used for helping target police patrols and other crime reduction initiatives. There are a number of spatial analysis techniques that can be used for identifying hotspots, but the most popular in recent years is kernel density estimation (KDE). KDE is popular because of the visually appealing way it represents the spatial distribution of crime, and because it is considered to be the most accurate of the commonly used hotspot mapping techniques. To produce KDE outputs, the researcher is required to enter values for two main parameters: the cell size and bandwidth size. To date little research has been conducted on the influence these parameters have on KDE hotspot mapping output, and none has been conducted on the influence these parameter settings have on a hotspot map’s central purpose – to identify where crime may occur in the future. We fill this gap with this research by conducting a number of experiments using different cell size and bandwidth values with crime data on residential burglary and violent assaults. We show that cell size has little influence on KDE crime hotspot maps for predicting spatial patterns of crime, but bandwidth size does have an influence. We conclude by discussing how the findings from this research can help inform police practitioners and researchers make better use of KDE for targeting policing and crime prevention initiatives
