1 It's All Geek to Me: Translating Names Of
IT’S ALL GEEK TO ME: TRANSLATING NAMES OF INSECTARIUM ARTHROPODS Prof. J. Phineas Michaelson, O.M.P. U.S. Biological and Geological Survey of the Territories Central Post Office, Denver City, Colorado Territory [or Year 2016 c/o Kallima Consultants, Inc., PO Box 33084, Northglenn, CO 80233-0084] ABSTRACT Kids today! Why don’t they know the basics of Greek and Latin? Either they don’t pay attention in class, or in many cases schools just don’t teach these classic languages of science anymore. For those who are Latin and Greek-challenged, noted (fictional) Victorian entomologist and explorer, Prof. J. Phineas Michaelson, will present English translations of the scientific names that have been given to some of the popular common arthropods available for public exhibits. This paper will explore how species get their names, as well as a brief look at some of the naturalists that named them. INTRODUCTION Our education system just isn’t what it used to be. Classic languages such as Latin and Greek are no longer a part of standard curriculum. Unfortunately, this puts modern students of science at somewhat of a disadvantage compared to our predecessors when it comes to scientific names. In the insectarium world, Latin and Greek names are used for the arthropods that we display, but for most young entomologists, these words are just a challenge to pronounce and lack meaning. Working with arthropods, we all know that Entomology is the study of these animals. Sounding similar but totally different, Etymology is the study of the origin of words, and the history of word meaning. -
Tarantulas and Social Spiders
Tarantulas and Social Spiders: A Tale of Sex and Silk by Jonathan Bull BSc (Hons) MSc ICL Thesis Presented to the Institute of Biology of The University of Nottingham in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy The University of Nottingham May 2012 DEDICATION To my parents… …because they both said to dedicate it to the other… I dedicate it to both ii ACKNOWLEDGEMENTS First and foremost I would like to thank my supervisor Dr Sara Goodacre for her guidance and support. I am also hugely endebted to Dr Keith Spriggs who became my mentor in the field of RNA and without whom my understanding of the field would have been but a fraction of what it is now. Particular thanks go to Professor John Brookfield, an expert in the field of biological statistics and data retrieval. Likewise with Dr Susan Liddell for her proteomics assistance, a truly remarkable individual on par with Professor Brookfield in being able to simplify even the most complex techniques and analyses. Finally, I would really like to thank Janet Beccaloni for her time and resources at the Natural History Museum, London, permitting me access to the collections therein; ten years on and still a delight. Finally, amongst the greats, Alexander ‘Sasha’ Kondrashov… a true inspiration. I would also like to express my gratitude to those who, although may not have directly contributed, should not be forgotten due to their continued assistance and considerate nature: Dr Chris Wade (five straight hours of help was not uncommon!), Sue Buxton (direct to my bench creepy crawlies), Sheila Keeble (ventures and cleans where others dare not), Alice Young (read/checked my thesis and overcame her arachnophobia!) and all those in the Centre for Biomolecular Sciences. -

Reproductive Biology of Uruguayan Theraphosids (Araneae, Mygalomorphae)
2002. The Journal of Arachnology 30:571±587 REPRODUCTIVE BIOLOGY OF URUGUAYAN THERAPHOSIDS (ARANEAE, MYGALOMORPHAE) Fernando G. Costa: Laboratorio de EtologõÂa, EcologõÂa y EvolucioÂn, IIBCE, Av. Italia 3318, Montevideo, Uruguay. E-mail: [email protected] Fernando PeÂrez-Miles: SeccioÂn EntomologõÂa, Facultad de Ciencias, Igua 4225, 11400 Montevideo, Uruguay ABSTRACT. We describe the reproductive biology of seven theraphosid species from Uruguay. Species under study include the Ischnocolinae Oligoxystre argentinense and the Theraphosinae Acanthoscurria suina, Eupalaestrus weijenberghi, Grammostola iheringi, G. mollicoma, Homoeomma uruguayense and Plesiopelma longisternale. Sexual activity periods were estimated from the occurrence of walking adult males. Sperm induction was described from laboratory studies. Courtship and mating were also described from both ®eld and laboratory observations. Oviposition and egg sac care were studied in the ®eld and laboratory. Two complete cycles including female molting and copulation, egg sac construction and emer- gence of juveniles were reported for the ®rst time in E. weijenberghi and O. argentinense. The life span of adults was studied and the whole life span was estimated up to 30 years in female G. mollicoma, which seems to be a record for spiders. A comprehensive review of literature on theraphosid reproductive biology was undertaken. In the discussion, we consider the lengthy and costly sperm induction, the widespread display by body vibrations of courting males, multiple mating strategies of both sexes and the absence of sexual cannibalism. Keywords: Uruguayan tarantulas, sexual behavior, sperm induction, life span Theraphosids are the largest and longest- PeÂrez-Miles et al. (1993), PeÂrez-Miles et al. lived spiders of the world.

Araneae (Spider) Photos
Araneae (Spider) Photos Araneae (Spiders) About Information on: Spider Photos of Links to WWW Spiders Spiders of North America Relationships Spider Groups Spider Resources -- An Identification Manual About Spiders As in the other arachnid orders, appendage specialization is very important in the evolution of spiders. In spiders the five pairs of appendages of the prosoma (one of the two main body sections) that follow the chelicerae are the pedipalps followed by four pairs of walking legs. The pedipalps are modified to serve as mating organs by mature male spiders. These modifications are often very complicated and differences in their structure are important characteristics used by araneologists in the classification of spiders. Pedipalps in female spiders are structurally much simpler and are used for sensing, manipulating food and sometimes in locomotion. It is relatively easy to tell mature or nearly mature males from female spiders (at least in most groups) by looking at the pedipalps -- in females they look like functional but small legs while in males the ends tend to be enlarged, often greatly so. In young spiders these differences are not evident. There are also appendages on the opisthosoma (the rear body section, the one with no walking legs) the best known being the spinnerets. In the first spiders there were four pairs of spinnerets. Living spiders may have four e.g., (liphistiomorph spiders) or three pairs (e.g., mygalomorph and ecribellate araneomorphs) or three paris of spinnerets and a silk spinning plate called a cribellum (the earliest and many extant araneomorph spiders). Spinnerets' history as appendages is suggested in part by their being projections away from the opisthosoma and the fact that they may retain muscles for movement Much of the success of spiders traces directly to their extensive use of silk and poison. -

THE MOLTING SEQUENCE IN APHONOPELMA CHALCODES (ARANEAE : THERAPOSIDAE ) Edwin W. Minch Department of Zoology Arizona State University Tempe, Arizona 8528 1 ABSTRAC T The molting sequence of Aphonopelma chalcodes is broken into ten steps and each characterized . Feeding is delayed several days after a molt as the exoskeleton hardens . Under artificial condition s molting may occur at any time during the day, but apparently occurs on a seasonal cycle . INTRODUCTION While several authors have investigated molting in the tarantula, the actual moltin g sequence has received little attention . Passmore (1939) gave three stages and illustrated them by photographs. Baerg (1958) gave a time of four hours for a tarantula to remain o n its dorsum before the carapace began to lift, and one hour and fifteen minutes fbr the actual molt. The purpose of this work is to give a detailed account of the molting sequence for the species Aphonopelma chalcodes Chamberlin, and to present evidence that this event is highly seasonal in its occurrence, but may take place at any time Of day . METHOD S Presumed adult female tarantulas were maintained in wide mouth gallon jars and wer e fed crickets or tenebrionid beetles on a weekly schedule . The temperature the tarantulas were maintained at varied from 24-27°C . OBSERVATIONS A total of twenty-five molts occurred over a two year period, four of which wer e observed in detail . For convenience, the entire sequence was divided into ten stages , which are summarized in Table 1 . -

Investigation of the Insulinotropic Peptides from the Venom of Aphonopelma Chalcodes and Grammostola Rosea Tarnatulas
RESEARCH GROUP: Diabetes Research Group Project Title: Investigation of the insulinotropic peptides from the venom of Aphonopelma chalcodes and Grammostola rosea tarnatulas. Supervisor(s): Dr Yasser Abdel-Wahab, Dr Stephen McClean and Professor Victor Gault Contact Details: [email protected] Level: PhD Background to the project : In studying the venom of Theraphosidae tarantulas we have uncovered a number of peptides that have potent in vitro activity promoting insulin release from the rodent insulin secreting cell line, BRIN-BD11. One of these, a 28-amino acid peptide from the venom of Aphonopelma chalcodes was purified by chromatography and structurally characterised using mass spectrometry and Edman degradation sequencing. The peptide was named Δ-theraphotoxin-Ac1 (Δ-TRTX-Ac1) according to existing nomenclature conventions. Our studies have shown that a synthetic version of Δ-TRTX-Ac1 is a potent insulinotropic peptide without any cytotoxic effects on rodent beta cells. Mechanistic studies revealed that Δ-TRTX-Ac1 was able to activate PKC-dependent pathway. While initial experiments have provided promising data, this novel peptide must be comprehensively tested in established animal models to fully determine its possible utility for type 2 diabetes therapy. In addition to Δ-TRTX-Ac1, a number of other insulinotropic peptides from Aphonopelma chalcodes and Grammostola rosea have been identified and require further investigation through full structural characterisation and functional activity assays. Objectives of the research project : The objectives of the research will be to investigate the insulinotropic properties of peptides derived from the tarantula species Aphonopelma chalcodes and Grammostola rosea. There will be two aspects to the PhD project, the first being an investigation of the Δ-TRTX-Ac1 peptide in animal models of diabetes and obesity. -
Morphology, Evolution and Usage of Urticating Setae by Tarantulas (Araneae: Theraphosidae)

Rodovia MGT 367, km 583, 39100-000 Diamantina, MG, Brazil. E-mail: [email protected] 3 Corresponding author. ABSTRACT. Urticating setae are exclusive to New World tarantulas and are found in approximately 90% of the New World species. Six morphological types have been proposed and, in several species, two morphological types can be found in the same individual. In the past few years, there has been growing concern to learn more about urticating setae, but many questions still remain unanswered. After studying individuals from several theraphosid species, we endeavored to find more about the segregation of the different types of setae into different abdominal regions, and the possible existence of patterns; the morphological variability of urticating setae types and their limits; whether there is variability in the length of urticating setae across the abdominal area; and whether spiders use different types of urticat- ing setae differently. We found that the two types of urticating setae, which can be found together in most theraphosine species, are segregated into distinct areas on the spider’s abdomen: type III occurs on the median and posterior areas with either type I or IV surrounding the patch of type III setae. -

Hembree Trace fossils are useful for interpreting the environmental conditions and ecological composition of strata. Neoichnological studies are necessary to provide informed interpretations, but few studies have examined the traces produced by continental species and how these organisms respond to changes in environmental conditions. Spiders are major predators in modern ecosystems. The fossil record of spiders extends to the Carboniferous, but few body fossils have been found earlier than the Cretaceous. Although the earliest spiders were probably burrowing species, burrows attributed to spiders are known primarily from the Pleistocene. The identification of spider burrows in the fossil record would allow for better paleoecological interpretations and provide a more complete understanding of the order’s evolutionary history. This study examines the morphology of burrows produced by the mygalomorph spider Gorgyrella inermis and the araneomorph spider Hogna lenta (Arachnida: Araneae).
