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. -

Arthropods of Elm Fork Preserve
Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux. -
The Effects of Native and Non-Native Grasses on Spiders, Their Prey, and Their Interactions
Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the GRADUATE DIVISION of the University of California, Berkeley Committee in charge: Professor Joe R. McBride, Chair Professor Rosemary G. Gillespie Professor Mary E. Power Spring 2014 © 2014 Abstract Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill Doctor of Philosophy in Environmental Science and Policy Management University of California, Berkeley Professor Joe R. McBride, Chair Found in nearly all terrestrial ecosystems, small in size and able to occupy a variety of hunting niches, spiders’ consumptive effects on other arthropods can have important impacts for ecosystems. This dissertation describes research into spider populations and their interactions with potential arthropod prey in California’s native and non-native grasslands. In meadows found in northern California, native and non-native grassland patches support different functional groups of arthropod predators, sap-feeders, pollinators, and scavengers and arthropod diversity is linked to native plant diversity. Wandering spiders’ ability to forage within the meadow’s interior is linked to the distance from the shaded woodland boundary. Native grasses offer a cooler conduit into the meadow interior than non-native annual grasses during midsummer heat. Juvenile spiders in particular, are more abundant in the more structurally complex native dominated areas of the grassland. -
Paraphysa Sp.)
RESEARCH MEALWORM (TENEBRIO MOLITOR) DIETS RELATIVE TO THE ENERGY REQUIREMENTS OF SMALL MYGALOMORPH SPIDERS (PARAPHYSA SP.) Lucia Canals, Vet Tech, Daniela Figueroa, Dr Vet Sc, Hugo Torres-Contreras, PhD, Claudio Veloso, PhD, and Mauricio Canals, MD, MS Sc, MS Abstract This article describes the basic prey requirements of Paraphysa sp., a small mygalomorph spider from the central Andes. Paraphysa sp. can be maintained in captivity using mealworms (Tenebrio molitor)asits primary food source. During a period of 66 days the prey requirements (larvae/day) were calculated for weight maintenance and compared with findings of previously reported resting and active metabolic rates. The spiders in this study ate at frequencies between 0.18 and 0.59 larvae/day, with an average of 0.43 Ϯ 0.14 larvae/day. From the regression line between frequency of feeding (larvae/day) and weight gain, we determined that 0.31 larvae/day were needed for a weight gain of 0. Thus, for the spiders to increase their weight, they would need to eat more than 1 larva every 3 days. This frequency yields a caloric intake of 0.193 kcal/d, or equivalently, a carbon dioxide production of 0.189 mL CO2/g·h. The findings in this report are greater than the resting metabolic rate at 35°C, and they agree with the active metabolic requirements of this spider in the field. Copyright 2012 Elsevier Inc.

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. -

Study Shows Some Spiders Have Individualized Personalities 31 July 2013, by Bob Yirka
Study shows some spiders have individualized personalities 31 July 2013, by Bob Yirka scientists suspect that the more social an organism type is the more likely there are to be differing personalities within a group. To learn which spiders might have which personality traits, the researchers went out into the field and bagged several spider nests and brought them back to the lab. After dissecting the nests, 40 specimens were chosen from each to serve as objects of study—each had colored spots applied to their backs to denote the level of aggression they exhibited when stimulated and to help in identifying them. Next, all of the spiders from the original nests were placed in artificial nests which were then placed in trees near the research facility. There, the Stegodyphus lineatus. Credit: Wikipedia researchers simulated insects being captured in webs and studied the actions of the spiders that occurred as a result. (Phys.org) —Researchers studying the In analyzing the data, the researchers found that Stegodyphus sarasinorum spider in India have those spiders that had exhibited the most found that individual specimens have different aggression in the first part of the study, were the personality traits from one another. In their paper very same ones that acted most boldly when published in Proceedings of the Royal Society B, insects became stuck in their webs—suggesting that the team report that some spiders in the field study individualized personality traits in the spiders tends exhibited more "boldness" than did others. to determine which sort of job they have—those that are bolder tend to be the ones that deal with Scientists have known for many years that animals captured prey, while those that are meeker wind up have distinct personalities—cats and dogs are nurturing offspring or engaging in other less prime examples. -
