Agric. & Cons . Serv. P.O. Box 1269 Gainesville, Florida 32602 USA ABSTRACT Over a seven-year period, approximately 35,000 spiders representing 26 families, 133 genera, and 234 species were captured in Washington County, Mississippi, by pitfall, sweepnet, vacuum, bag, and hand. Specimens were collected in 10 different habitat types and in four vegetational strata . Old-field habitats yielded the most species (152) and residential lawns the fewest (14) . Considering all habitats sampled, the ground layer produced 111 species, the herbaceous strata 133, the shrub layer 49, and the tree strata 30 species . The sweepnet method of capture obtained 128 species, pitfall 95, hand 61, vacuum 53, and bagging 19 species. The largest number of species were obtained in spring and early summer (maximum of 125 in May), with the fewest in mid-winter (Jan . = 24) . Twenty-one species were considered abundant, 51 common, 67 uncommon, and 95 rare . Additions to the state list of Dorris (1972) number 102 species, for a new state total of 364 species . A comparison with the North American fauna and with other surveys indicates that Washington County is underrepresented both in cursorial forms active on the soil surface and web-spinning forms typical of undisturbed habitats . -

Abundance and Community Composition of Arboreal Spiders: the Relative Importance of Habitat Structure
AN ABSTRACT OF THE THESIS OF Juraj Halaj for the degree of Doctor of Philosophy in Entomology presented on May 6, 1996. Title: Abundance and Community Composition of Arboreal Spiders: The Relative Importance of Habitat Structure. Prey Availability and Competition. Abstract approved: Redacted for Privacy _ John D. Lattin, Darrell W. Ross This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed the importance of several habitat variables as predictors of spider abundance and diversity on and among individual tree species. The greatest abundance and species richness of spiders per 1-m-long branch tips were found on structurally more complex tree species, including Douglas-fir, Pseudotsuga menziesii (Mirbel) Franco and noble fir, Abies procera Rehder. Spider densities, species richness and diversity positively correlated with the amount of foliage, branch twigs and prey densities on individual tree species. The amount of branch twigs alone explained almost 70% of the variation in the total spider abundance across five tree species. In 1994, I experimentally tested the importance of needle density and branching complexity of Douglas-fir branches on the abundance and community structure of spiders and their potential prey organisms. This was accomplished by either removing needles, by thinning branches or by tying branches. Tying branches resulted in a significant increase in the abundance of spiders and their prey. Densities of spiders and their prey were reduced by removal of needles and thinning. -
Reflections on the Tapetum Lucidum and Eyeshine in Lycosoid Spiders
2013. The Journal of Arachnology 41:43–52 Reflections on the tapetum lucidum and eyeshine in lycosoid spiders Kari Benson: School of Sciences, Lynchburg College, 1501 Lakeside Dr., Lynchburg, Virginia 24501, USA. E-mail: [email protected] Robert B. Suter: Department of Biology, Vassar College, 124 Raymond Avenue, Poughkeepsie, New York 12603, USA Abstract. In the lycosoid spiders, the secondary eyes possess a grate-shaped tapetum lucidum that reflects light, causing eyeshine when these spiders are viewed with approximately coaxial illumination. This guanine-based reflective surface is thought to increase visual capabilities in low light. We explored the eyeshine of the posterior medial eye in eight taxa of pisaurid and lycosid spiders. The taxa included four pisaurids: Dolomedes tenebrosus Hentz 1844, D. triton (Walckenaer 1837), D. scriptus Hentz 1845 and D. vittatus Walckenaer 1837; and four lycosids: Gladicosa pulchra (Keyserling 1877), Hogna sp. (cf. Lycosa lenta (Hentz 1844) sensu Wallace 1942), Rabidosa punctulata (Hentz 1844) and Varacosa avara (Keyserling 1877). We found that there were significant family- and species-level differences in both the reflected spectra and the intensity of reflection. Although the peaks of the reflected spectra were in the green range for all spiders, the mean peak was further toward the blue end of the spectrum for the lycosids than for the pisaurids. Variation among species (about 54% of the total variation) was dominated by G. pulchra (Lycosidae) and D. vittatus (Pisauridae), both of whose spectra peaked near yellow, vs. V. avara (Lycosidae), whose spectra peaked to the blue side of green. The lycosid spiders showed overall brighter eyeshine. -

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. -
Estimating Spider Species Richness in a Southern Appalachian Cove Hardwood Forest
1996. The Journal of Arachnology 24:111-128 ESTIMATING SPIDER SPECIES RICHNESS IN A SOUTHERN APPALACHIAN COVE HARDWOOD FOREST Jonathan A. Coddington: Dept. of Entomology, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20560 USA Laurel H. Young and Frederick A. Coyle: Dept. of Biology, Western Carolina University, Cullowhee, North Carolina 28723 USA ABSTRACT. Variation in species richness at the landscape scale is an important consideration in con- servation planning and natural resource management. To assess the ability of rapid inventory techniques to estimate local species richness, three collectors sampled the spider fauna of a "wilderness" cove forest in the southern Appalachians for 133 person-hours during September and early October 1991 using four methods: aerial hand collecting, ground hand collecting, beating, and leaf litter extraction. Eighty-nine species in 64 genera and 19 families were found. To these data we applied various statistical techniques (lognormal, Poisson lognormal, Chao 1, Chao 2, jackknife, and species accumulation curve) to estimate the number of species present as adults at this site. Estimates clustered between roughly 100-130 species with an outlier (Poisson lognormal) at 182 species. We compare these estimates to those from Bolivian tropical forest sites sampled in much the same way but less intensively. We discuss the biases and errors such estimates may entail and their utility for inventory design. We also assess the effects of method, time of day and collector on the number of adults, number of species and taxonomic composition of the samples and discuss the nature and importance of such effects. Method, collector and method-time of day interaction significantly affected the numbers of adults and species per sample; and each of the four methods collected clearly different sets of species. -

2016 Persons Mercury Content Spiders
Variation in total mercury content among riparian and non-riparian spider species Hailey Shannon, Derek Wilson, Tara Barbarich, Brian Mangan*, and Matthew Persons Dept. of Biology, Susquehanna University, Selinsgrove, PA 17870 *Dept. of Biology, King’s College, Wilkes-Barre, PA 18711 ABSTRACT Spiders collected and Mercury is a persistent environmental contaminant that primarily originates from coal-fired Spiders prepared power plants but may arise from other sources including uncontrolled mine fires. Variation in Collected spiders were rinsed total mercury uptake and mobilization through the apex arthropod community is poorly identified (N = 672) with water for at least 10 understood. We measured total mercury among ground and web-building spiders at sites along the Susquehanna River near a coal-fired power plant and compared total mercury levels seconds and placed in small to spiders from uncontrolled coal fire burn sites (Centralia, PA and Laurel Run, PA) and Spiders were labeled containers. Spiders reference sites away from the river or point sources of mercury pollution (agricultural fields collected from 6 sites were kept frozen until and headwater streams). We measured total mercury across species, age classes, and sexes from June to analyzed. for several species of ground spider and a web-building spider at these sites. Spiders from November of 2015 mine fire sites had total mercury levels over 2.5 times higher than those in riparian zones and 2016. Tetragnatha elongata Spiders analyzed for Hg adjacent to the power plant and about six times higher than those from agricultural fields or Spiders were sent to King’s riparian zones away from power plants.
