Sexual Selection Research on Spiders: Progress and Biases
Biol. Rev. (2005), 80, pp. 363–385. f Cambridge Philosophical Society 363 doi:10.1017/S1464793104006700 Printed in the United Kingdom Sexual selection research on spiders: progress and biases Bernhard A. Huber* Zoological Research Institute and Museum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany (Received 7 June 2004; revised 25 November 2004; accepted 29 November 2004) ABSTRACT The renaissance of interest in sexual selection during the last decades has fuelled an extraordinary increase of scientific papers on the subject in spiders. Research has focused both on the process of sexual selection itself, for example on the signals and various modalities involved, and on the patterns, that is the outcome of mate choice and competition depending on certain parameters. Sexual selection has most clearly been demonstrated in cases involving visual and acoustical signals but most spiders are myopic and mute, relying rather on vibrations, chemical and tactile stimuli. This review argues that research has been biased towards modalities that are relatively easily accessible to the human observer. Circumstantial and comparative evidence indicates that sexual selection working via substrate-borne vibrations and tactile as well as chemical stimuli may be common and widespread in spiders. Pattern-oriented research has focused on several phenomena for which spiders offer excellent model objects, like sexual size dimorphism, nuptial feeding, sexual cannibalism, and sperm competition. The accumulating evidence argues for a highly complex set of explanations for seemingly uniform patterns like size dimorphism and sexual cannibalism. Sexual selection appears involved as well as natural selection and mechanisms that are adaptive in other contexts only. Sperm competition has resulted in a plethora of morpho- logical and behavioural adaptations, and simplistic models like those linking reproductive morphology with behaviour and sperm priority patterns in a straightforward way are being replaced by complex models involving an array of parameters. -
Spiders (Araneae) of Churchill, Manitoba: DNA Barcodes And
Blagoev et al. BMC Ecology 2013, 13:44 http://www.biomedcentral.com/1472-6785/13/44 RESEARCH ARTICLE Open Access Spiders (Araneae) of Churchill, Manitoba: DNA barcodes and morphology reveal high species diversity and new Canadian records Gergin A Blagoev1*, Nadya I Nikolova1, Crystal N Sobel1, Paul DN Hebert1,2 and Sarah J Adamowicz1,2 Abstract Background: Arctic ecosystems, especially those near transition zones, are expected to be strongly impacted by climate change. Because it is positioned on the ecotone between tundra and boreal forest, the Churchill area is a strategic locality for the analysis of shifts in faunal composition. This fact has motivated the effort to develop a comprehensive biodiversity inventory for the Churchill region by coupling DNA barcoding with morphological studies. The present study represents one element of this effort; it focuses on analysis of the spider fauna at Churchill. Results: 198 species were detected among 2704 spiders analyzed, tripling the count for the Churchill region. Estimates of overall diversity suggest that another 10–20 species await detection. Most species displayed little intraspecific sequence variation (maximum <1%) in the barcode region of the cytochrome c oxidase subunit I (COI) gene, but four species showed considerably higher values (maximum = 4.1-6.2%), suggesting cryptic species. All recognized species possessed a distinct haplotype array at COI with nearest-neighbour interspecific distances averaging 8.57%. Three species new to Canada were detected: Robertus lyrifer (Theridiidae), Baryphyma trifrons (Linyphiidae), and Satilatlas monticola (Linyphiidae). The first two species may represent human-mediated introductions linked to the port in Churchill, but the other species represents a range extension from the USA. -
Awenda Provincial Park
AWENDA PROVINCIAL PARK One Malaise trap was deployed at Awenda Provincial Park in 2014 (44.82534, -79.98458, 231m ASL; Figure 1). This trap collected arthropods for twenty weeks from April 29 – September 19, 2014. All 10 Malaise trap samples were processed; every other sample was analyzed using the individual specimen protocol while the second half was analyzed via bulk analysis. A total of 3029 BINs were obtained. Over half the BINs captured were flies (Diptera), followed by bees, ants and wasps (Hymenoptera), moths and butterflies (Lepidoptera), and true bugs (Hemiptera; Figure 2). In total, 595 arthropod species were named, representing 21.3% of the BINs from the Figure 1. Malaise trap deployed at Awenda Provincial site (Appendix 1). All the BINs were assigned at least Park in 2014. to family, and 54% were assigned to a genus (Appendix 2). Specimens collected from Awenda represent 214 different families and 705 genera.

Synanthropic Spiders, Including the Global Invasive Noble False Widow
www.nature.com/scientificreports OPEN Synanthropic spiders, including the global invasive noble false widow Steatoda nobilis, are reservoirs for medically important and antibiotic resistant bacteria John P. Dunbar1,5*, Neyaz A. Khan2,5, Cathy L. Abberton3, Pearce Brosnan3, Jennifer Murphy3, Sam Afoullouss4, Vincent O’Flaherty2,3, Michel M. Dugon1 & Aoife Boyd2 The false widow spider Steatoda nobilis is associated with bites which develop bacterial infections that are sometimes unresponsive to antibiotics. These could be secondary infections derived from opportunistic bacteria on the skin or infections directly vectored by the spider. In this study, we investigated whether it is plausible for S. nobilis and other synanthropic European spiders to vector bacteria during a bite, by seeking to identify bacteria with pathogenic potential on the spiders. 11 genera of bacteria were identifed through 16S rRNA sequencing from the body surfaces and chelicerae of S. nobilis, and two native spiders: Amaurobius similis and Eratigena atrica. Out of 22 bacterial species isolated from S. nobilis, 12 were related to human pathogenicity among which Staphylococcus epidermidis, Kluyvera intermedia, Rothia mucilaginosa and Pseudomonas putida are recognized as class 2 pathogens. The isolates varied in their antibiotic susceptibility: Pseudomonas putida, Staphylococcus capitis and Staphylococcus edaphicus showed the highest extent of resistance, to three antibiotics in total. On the other hand, all bacteria recovered from S. nobilis were susceptible to ciprofoxacin. Our study demonstrates that S. nobilis does carry opportunistic pathogenic bacteria on its body surfaces and chelicerae. Therefore, some post-bite infections could be the result of vector- borne bacterial zoonoses that may be antibiotic resistant. Bacterial infections represent a major threat to human health. -

Scottish Spiders - Oonopspulcher 15Mm
Scottish Spiders BeesIntroduction and wasps to spider families There are approximately 670 species of spider in 38 different families in the UK. This guide introduces 17 families of spiders, providing an example of a species or genus to look for in each. Please Note: The vast majority of spiders in the UK need examination under a microscope of mature adults to confirm species. Immature specimens may be identified to family or to genus level and often only by an expert. This guide has been designed to introduce several families with information on key features in each and is not an identification guide. Woodlouse spiders (Family Dysderidae) 4 species in 2 genera Rather elongate looking spiders with no clear markings or Woodlouse spider (female) pattern on their cylindrical abdomen. They have six eyes that are clustered together in a circular formation. Often found under stones, logs, tree bark and other debris. Typical body length in family ranges from 6-15mm. Species to look out for - Woodlouse spider (Dysdera crocata) A distinctive species with a red cephalothorax and legs and forward projecting chelicerae. This species feeds on woodlice and can be found under stones and debris in warm (and sometimes) slightly damp situations. Generally nocturnal - look for them in gardens and on walls where they may be found sheltering in silken retreats. This species is common in England but less so in Scotland, being absent from the very north. Look out for Harpactea hombergi which although similar in Male: 9—10mm Female: 11—15mm appearance has a narrower cephalothorax and with less Falk © Steven prominent chelicerae. -
Black Carpenter Ants in the Ozark Mountains of Arkansas: Relationships with Prescribed Fire, Site and Stand Variables, and Red Oak Borer
BLACK CARPENTER ANTS IN THE OZARK MOUNTAINS OF ARKANSAS: RELATIONSHIPS WITH PRESCRIBED FIRE, SITE AND STAND VARIABLES, AND RED OAK BORER BLACK CARPENTER ANTS IN THE OZARK MOUNTAINS OF ARKANSAS: RELATIONSHIPS WITH PRESCRIBED FIRE, SITE AND STAND VARIABLES, AND RED OAK BORER A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology By ROBIN MICHELLE VERBLE University of Southern Indiana Bachelor of Science in Biophysics, 2006 August 2008 University of Arkansas ABSTRACT Black carpenter ants, Camponotus pennsylvanicus DeGeer, are nearly ubiquitous in eastern North American forests. These ants are documented as predators of red oak borer, Enaphalodes rufulus Haldeman, a native longhorn beetle that underwent an unprecedented population increase and decline in the oak hickory forests of the Ozark Mountains of Arkansas from the late 1990’s to 2005. My objective was to examine red oak borer emergence holes and site aspects and correlate these forest and tree attributes with presence or absence of black carpenter ants. Historic red oak borer population data, tree REP class and site aspects for 13 separate plots were used. At each site, all red oaks >10 cm DBH were baited for black carpenters ants using a mixture of tuna in oil and honey. Black carpenter ants are more likely to be found on trees with low levels of previous red oak borer infestation versus those trees with previously high levels of infestation. These results may suggest black carpenter ants play a role in controlling red oak borer populations. Distribution of black carpenter ants in red oaks prior to and during the outbreak is unknown. -

In a survey investigating the spider fauna of Dargaz and Kalat counties in Razavi Khorasan Province of Iran, 13 families and 21 species were recognized, of which three are new to Iran: Minosia simeonica Levy, 1995, Nomisia negebensis Levy, 1995 and Thanatus atratus Simon, 1875. Also, genus Minosia Dalmas, 1921 is recorded for the first time in Iran. Data on collection localities and distribution of each species, as well as diagnostic morphological characters and figures for the newly recorded taxa are provided. Key words: new records, Thanatus, Minosia, Nomisia, Iran. Introduction Spiders (Araneae), with over 45000 recognized species in the world (World Spider Catalog 2015). Reviewing the literature, Zamani et al. (2015a) gave a checklist of spiders of Iran with about 540 species. Considering the geographic position of the country as a land bridge joining the Palaearctic, Afro- tropical and Oriental zones, and its diverse climate condi- tions and the known spider fauna of adjacent countries, it seems that this number must be much higher than known at present.
