  • The Efficiency of Sound Production in Two Cricket Species, Gryllotalpa Australis and Teleogryllus Commodus (Orthoptera: Grylloidea)
    J. exp. Biol. 130, 107-119 (1987) 107 Printed in Great Britain © The Company of Biologists Limited 1987 THE EFFICIENCY OF SOUND PRODUCTION IN TWO CRICKET SPECIES, GRYLLOTALPA AUSTRALIS AND TELEOGRYLLUS COMMODUS (ORTHOPTERA: GRYLLOIDEA) BY MARK W. KAVANAGH Department of Zoology, University of Melbourne, Parkville, Victoria, 3052, Australia Accepted 27 February 1987 SUMMARY 1. Males of Gryllotalpa australis (Erichson) (Gryllotalpidae) and Teleogryllus commodus (Walter) (Gryllidae) produced their calling songs while confined in respirometers. 2. G. australis males used oxygen during calling at a mean rate of 4-637 ml O2h^', equivalent to 27-65mW of metabolic energy, which was 13 times higher than the resting metabolic rate. T. commodus males used oxygen during calling at a rate of 0-728 ml O2h~', equivalent to 4-34mW, which was four times the resting metabolic rate. 3. The sound field during calling by males represents a sound power output of 0-27 mW for G. australis and l-51XlO~3mW for T. commodus. 4. The efficiency of sound production was 1-05% for males of G. australis and 0-05 % for males of T. commodus. Comparison with other insect species suggests that none is more than a few percent efficient in sound production. INTRODUCTION Many insect species produce stereotyped acoustic signals that are important in intraspecific communication. In most species that communicate by sound, the male's calling song, which seems to attract conspecific females, is the most obvious and the most important component of the repertoire. Production of the calling song will involve a cost to the producer in the form of an increased use of metabolic energy.

  • Virus Particle Structures
    Virus Particle Structures Virus Particle Structures Palmenberg, A.C. and Sgro, J.-Y. COLOR PLATE LEGENDS These color plates depict the relative sizes and comparative virion structures of multiple types of viruses. The renderings are based on data from published atomic coordinates as determined by X-ray crystallography. The international online repository for 3D coordinates is the Protein Databank (www.rcsb.org/pdb/), maintained by the Research Collaboratory for Structural Bioinformatics (RCSB). The VIPER web site (mmtsb.scripps.edu/viper), maintains a parallel collection of PDB coordinates for icosahedral viruses and additionally offers a version of each data file permuted into the same relative 3D orientation (Reddy, V., Natarajan, P., Okerberg, B., Li, K., Damodaran, K., Morton, R., Brooks, C. and Johnson, J. (2001). J. Virol., 75, 11943-11947). VIPER also contains an excellent repository of instructional materials pertaining to icosahedral symmetry and viral structures. All images presented here, except for the filamentous viruses, used the standard VIPER orientation along the icosahedral 2-fold axis. With the exception of Plate 3 as described below, these images were generated from their atomic coordinates using a novel radial depth-cue colorization technique and the program Rasmol (Sayle, R.A., Milner-White, E.J. (1995). RASMOL: biomolecular graphics for all. Trends Biochem Sci., 20, 374-376). First, the Temperature Factor column for every atom in a PDB coordinate file was edited to record a measure of the radial distance from the virion center. The files were rendered using the Rasmol spacefill menu, with specular and shadow options according to the Van de Waals radius of each atom.

Predicting the outcome of infection with novel combinations of 14 virus and host remains a key challenge in virus research. Host evolutionary relatedness can explain 15 variation in transmission rates, virulence, and virus community composition between host species, 16 but there is much to learn about the potential for virus evolutionary relatedness to explain variation 17 in the ability of viruses to infect novel hosts. Here, we measure correlations in the outcomes of 18 infection across 45 Drosophilidae host species with four Cripavirus isolates that vary in their 19 evolutionary relatedness. We found positive correlations between every pair of viruses tested, with 20 the strength of correlation tending to decrease with greater evolutionary distance between viruses. 21 These results suggest that virus evolutionary relatedness can explain variation in the outcome of 22 host shifts and may be a useful proxy for determining the likelihood of novel virus emergence.

  • An Alternative Hypothesis for the Evolution of Same-Sex Sexual Behaviour in Animals
    PERSPECTIVE https://doi.org/10.1038/s41559-019-1019-7 Corrected: Author Correction An alternative hypothesis for the evolution of same-sex sexual behaviour in animals Julia D. Monk 1*, Erin Giglio 2, Ambika Kamath3,4, Max R. Lambert 4 and Caitlin E. McDonough 5 Same-sex sexual behaviour (SSB) has been recorded in over 1,500 animal species with a widespread distribution across most major clades. Evolutionary biologists have long sought to uncover the adaptive origins of ‘homosexual behaviour’ in an attempt to resolve this apparent Darwinian paradox: how has SSB repeatedly evolved and persisted despite its presumed fitness costs? This question implicitly assumes that ‘heterosexual’ or exclusive different-sex sexual behaviour (DSB) is the baseline condition for animals, from which SSB has evolved. We question the idea that SSB necessarily presents an evolutionary conundrum, and suggest that the literature includes unchecked assumptions regarding the costs, benefits and origins of SSB. Instead, we offer an alternative null hypothesis for the evolutionary origin of SSB that, through a subtle shift in perspective, moves away from the expectation that the origin and maintenance of SSB is a problem in need of a solution. We argue that the frequently implicit assumption of DSB as ancestral has not been rigorously examined, and instead hypothesize an ancestral condition of indiscrimi- nate sexual behaviours directed towards all sexes. By shifting the lens through which we study animal sexual behaviour, we can more fruitfully examine the evolutionary history of diverse sexual strategies. ince Charles Darwin1,2 first recognized natural and sexual this apparent paradox have taken the form of taxon-specific searches selection as engines of evolutionary change, considerations of for adaptive and non-adaptive explanations of SSB (reviewed in Ssex and fitness in evolutionary biology have largely focused refs.

  • Immune Function Reflected in Calling Song Characteristics in a Natural
    ANIMAL BEHAVIOUR, 2005, 69, 1235–1241 doi:10.1016/j.anbehav.2004.09.011 Immune function reflected in calling song characteristics in a natural population of the cricket Teleogryllus commodus LEIGH W. SIMMONS*,MARLENEZUK† &JOHNT.ROTENBERRY† *Evolutionary Biology Research Group, School of Animal Biology (M092), The University of Western Australia yDepartment of Biology, University of California, Riverside (Received 9 February 2004; initial acceptance 30 March 2004; final acceptance 24 September 2004; published online 17 February 2005; MS. number: 7999R) Secondary sexual traits have been suggested to provide reliable signals of a male’s ability to resist infection by agents of disease. The immunocompetence handicap hypothesis provides a potential mechanism for reliable signalling in the form of a trade-off between expenditure on trait expression and expenditure on immunity. Thus, males resistant to disease can spend more resources on their sexual signals. Examination of calling song parameters in a natural population of the cricket Teleogryllus commodus revealed that males scoring higher on the third principal component for song had significantly lower ability to encapsulate a foreign object. This component of immune function was associated with syllables of longer duration in both the trill and chirp elements of the song. Males with longer syllables in their song had a lower encapsulation ability. Syllable duration is known to influence phonotaxis by female T. commodus. Although the effect was only weak, our data suggest that females may base their choice of mate on reliable information contained within the temporal properties of male calls. Our study thus demonstrates a connection between sexual signalling and immune function in a natural population of insects and lends support to the immunocompetence handicap hypothesis.

  • Variation and Repeatability of Calling Behavior in Crickets Subject to a Phonotactic Parasitoid Fly
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by DigitalCommons@CalPoly Variation and Repeatability of Calling Behavior in Crickets Subject to a Phonotactic Parasitoid Fly Gita Raman Kolluru1 Male Teleogryllus oceanicus (Orthoptera: Gryllidae) produce a conspicuous calling song to attract females. In some populations, the song also attracts the phonotactic parasitoid fly Ormia ochracea (Diptera: Tachinidae). I examined the factors affecting calling song by characterizing the calling behavior of caged crickets from an area where the fly occurs. Calling activity (proportion of time spent calling) was repeatable and a significant predictor of female attraction. However, calling activity in the parasitized population was lower than in an unparasitized Moorea population (Orsak, 1988), suggesting a compromise between high activity to attract females and low activity to avoid flies. Calling activity peaked simultaneously with fly searching, so crickets did not shift to calling when the fly is less active. Males harboring larvae did not call less than unparasitized males; however, a more controlled study of the effects of parasitization on calling behavior is needed to evaluate this result. The results are discussed in the context of other studies of the evolutionary consequences of sexual and natural selection on cricket calling behavior. KEY WORDS: crickets; acoustic signals; calling duration; calling activity; calling patterns; phonotactic parasitoids; repeatability; Orthoptera; Gryllidae; Teleogryllus; Ormia. INTRODUCTION Male field crickets produce a conspicuous, long-range calling song to attract females for mating. However, the song may also attract acoustically-orienting natural enemies (Zuk and Kolluru, 1998).

  • 2008.005I (To Be Completed by ICTV Officers)
    Taxonomic proposal to the ICTV Executive Committee This form should be used for all taxonomic proposals. Please complete all those modules that are applicable (and then delete the unwanted sections). Code(s) assigned: 2008.005I (to be completed by ICTV officers) Short title: Creation of a new species in the genus, Cripavirus, family Dicistroviridae (e.g. 6 new species in the genus Zetavirus; re-classification of the family Zetaviridae etc.) Modules attached 1 2 3 4 5 (please check all that apply): 6 7 Author(s) with e-mail address(es) of the proposer: Dicistroviridae Study Group: Nobuhiko Nakashima ([email protected]), Karyn Johnson ([email protected]); Frank van der Wilk ([email protected]); Les Domier: ([email protected]); Peter Christian ([email protected]); Judy Chen ([email protected]) ; Tamas Bakonyi ([email protected]). ICTV-EC or Study Group comments and response of the proposer: MODULE 5: NEW SPECIES Code 2008.005I (assigned by ICTV officers) To create Homalodisca coagulata virus-1, a new species assigned as follows: Fill in all that apply. Ideally, species Genus: Cripavirus should be placed within a genus, but Subfamily: it is acceptable to propose a species Family: Dicistroviridae that is within a Subfamily or Family Order: Picornavirales but not assigned to an existing genus (in which case put “unassigned” in the genus box) Name(s) of proposed new species: Homalodisca coagulata virus-1 Argument to justify the creation of the new species: If the species are to be assigned to an existing genus, list the criteria for species demarcation and explain how the proposed members meet these criteria.

  • ARTHROPODA Subphylum Hexapoda Protura, Springtails, Diplura, and Insects
    NINE Phylum ARTHROPODA SUBPHYLUM HEXAPODA Protura, springtails, Diplura, and insects ROD P. MACFARLANE, PETER A. MADDISON, IAN G. ANDREW, JOCELYN A. BERRY, PETER M. JOHNS, ROBERT J. B.

TEULON, TERRY R. HITCHINGS, VICTOR F. EASTOP, NICHOLAS A. MARTIN, MURRAY J. FLETCHER, MARLON A. W. STUFKENS, PAMELA J. DALE, Daniel BURCKHARDT, THOMAS R. BUCKLEY, STEVEN A. TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).
