Ladder Webs in Orb-Web Spiders: Ontogenetic and Evolutionary Patterns in Nephilidae
Biological Journal of the Linnean Society, 2010, 99, 849–866. With 4 figures Ladder webs in orb-web spiders: ontogenetic and evolutionary patterns in Nephilidae MATJAŽ KUNTNER1,2*, SIMONA KRALJ-FIŠER1 and MATJAŽ GREGORICˇ 1 1Institute of Biology, Scientific Research Centre, Slovenian Academy of Sciences and Arts, Novi trg 2, PO Box 306, SI-1001 Ljubljana, Slovenia 2Department of Entomology, National Museum of Natural History, Smithsonian Institution, NHB-105, PO Box 37012, Washington, D.C. 20013-7012, USA Received 18 September 2009; accepted for publication 10 November 2009bij_1414 849..866 Spider web research bridges ethology, ecology, functional morphology, material science, development, genetics, and evolution. Recent work proposes the aerial orb web as a one-time key evolutionary innovation that has freed spider-web architecture from substrate constraints. However, the orb has repeatedly been modified or lost within araneoid spiders. Modifications include not only sheet- and cobwebs, but also ladder webs, which secondarily utilize the substrate. A recent nephilid species level phylogeny suggests that the ancestral nephilid web architecture was an arboricolous ladder and that round aerial webs were derived. Because the web biology of the basalmost Clitaetra and the derived Nephila are well understood, the present study focuses on the webs of the two phylogenetically intervening genera, Herennia and Nephilengys, to establish ontogenetic and macroevolutionary patterns across the nephilid tree. We compared juvenile and adult webs of 95 Herennia multipuncta and 143 Nephilengys malabarensis for two measures of ontogenetic allometric web changes: web asymmetry quantified by the ladder index, and hub asymmetry quantified by the hub displacement index. We define a ‘ladder web’ as a vertically elongated orb exceeding twice the length over width (ladder index Ն 2) and possessing (sub)parallel rather than round side frames. -

This was studied from September 2015 to July 2019. A total of 18 family, 52 genus and 80 species were recorded. Araneidae is the most dominant family among all followed by the silicide family. The main aim of this study is to bring to known the species which is generally observed by the humans in this area. Beside seasonal variation in species is higher in summer season as compared to winter. Also many species were observed each year in same season repeatedly during the study period, further maximum number of species is seen in vegetation type of habitat. Keywords: Spider, diversity, Tinsukia, seasonal, habitat 1. Introduction As one of the most widely recognized group of Arthropods, Spiders are widespread in distribution except for a few niches, such as Arctic and Antarctic. Almost every plant has its spider fauna, as do dead leaves, on the forest floor and on the trees. They may be found at varied locations, such as under bark, beneath stones, below the fallen logs, among foliage, [23] house dwellings, grass, leaves, underground, burrows etc. (Pai IK., 2018) . Their success is reflected by the fact that, on our planet, there are about 48,358 species recorded till now according to World Spider Catalog. -

A Checklist of the Spiders of Tanzania
Journal of East African Natural History 109(1): 1–41 (2020) A CHECKLIST OF THE SPIDERS OF TANZANIA A. Russell-Smith 1, Bailiffs Cottage, Doddington, Sittingbourne Kent ME9 0JU, UK [email protected] ABSTRACT A checklist of all published spider species from Tanzania is provided. For each species, the localities from which it was recorded are noted and a gazetteer of the geographic coordinates of all but a small minority of these localities is included. The results are discussed in terms of family species richness, the completeness of our knowledge of the spider fauna of this country and the likely biases in family composition. Keywords: Araneae, East Africa, faunistics, biodiversity INTRODUCTION Students of spiders are very fortunate in having a complete online catalogue that is continuously updated—the World Spider Catalog (http://www.wsc.nmbe.ch/). The catalogue also provides full text of virtually all the relevant systematic literature, allowing ready access to taxonomic accounts for all species. However, researchers interested in the spiders of a particular country face two problems in using the catalogue: 1. For species that have a widespread distribution, the catalogue often lists only the region (e.g. “East Africa”) or even the continent (“Africa”) from which it is recorded 2. The catalogue itself provides no information on the actual locations from which a species is recorded. There is thus a need for more detailed country checklists, particularly those outside the Palaearctic and Nearctic regions where most arachnologists have traditionally been based. In addition to providing an updated list of species from the country concerned, such catalogues can provide details of the actual locations from which each species has been recorded, together with geographical coordinates when these are available. -

We synthesize the available data for the genera Nephila, Nephilengys, Herennia and Clitaetra to produce the first species level phylogeny of the family. We score 231 characters (197 morphological, 34 behavioral) for 61 taxa: 32 of the 37 known nephilid species plus two Phonognatha and one Deliochus species, 10 tetragnathid outgroups, nine araneids, and one genus each of Nesticidae, Theridiidae, Theridiosomatidae, Linyphiidae, Pimoidae, Uloboridae and Deinopidae. Four most parsimonious trees resulted, among which successive weighting preferred one ingroup topology. Neither an analysis of an alternative data set based on different morphological interpretations, nor separate analyses of morphology and behavior are superior to the total evidence analysis, which we therefore propose as the working hypothesis of nephilid relationships, and the basis for classification. Ingroup generic relationships are (Clitaetra (Herennia (Nephila, Nephilengys))). Deliochus and Phonognatha group with Araneidae rather than Nephilidae. Nephilidae is sister to all other araneoids (contra most recent literature). -
High Throughput Techniques to Reveal the Molecular Physiology and Evolution of Digestion in Spiders Felipe J
Fuzita et al. BMC Genomics (2016) 17:716 DOI 10.1186/s12864-016-3048-9 RESEARCH ARTICLE Open Access High throughput techniques to reveal the molecular physiology and evolution of digestion in spiders Felipe J. Fuzita1,2, Martijn W. H. Pinkse3, José S. L. Patane4, Peter D. E. M. Verhaert3,5 and Adriana R. Lopes1* Abstract Background: Spiders are known for their predatory efficiency and for their high capacity of digesting relatively large prey. They do this by combining both extracorporeal and intracellular digestion. Whereas many high throughput (“-omics”) techniques focus on biomolecules in spider venom, so far this approach has not yet been applied to investigate the protein composition of spider midgut diverticula (MD) and digestive fluid (DF). Results: We here report on our investigations of both MD and DF of the spider Nephilingis (Nephilengys) cruentata through the use of next generation sequencing and shotgun proteomics. This shows that the DF is composed of a variety of hydrolases including peptidases, carbohydrases, lipases and nuclease, as well as of toxins and regulatory proteins. We detect 25 astacins in the DF. Phylogenetic analysis of the corresponding transcript(s) in Arachnida suggests that astacins have acquired an unprecedented role for extracorporeal digestion in Araneae, with different orthologs used by each family. The results of a comparative study of spiders in distinct physiological conditions allow us to propose some digestion mechanisms in this interesting animal taxon. Conclusion: All the high throughput data allowed the demonstration that DF is a secretion originating from the MD. We identified enzymes involved in the extracellular and intracellular phases of digestion. -
Vibratory Signalling in Two Spider Species with Contrasting Web Architectures
Vibratory signalling in two spider species with contrasting web architectures by Samantha Vibert M.Sc., Université de Genève, 2002 B.Sc., Université de Genève, 2000 Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Department of Biological Sciences Faculty of Science Samantha Vibert 2016 SIMON FRASER UNIVERSITY Summer 2016 Approval Name: Samantha Vibert Degree: Doctor of Philosophy (Biological Sciences) Title: Vibratory signalling in two spider species with contrasting web architectures Examining Committee: Chair: Michael Hart Professor Gerhard Gries Senior Supervisor Professor Bernard Roitberg Supervisor Professor Emeritus Robert G. Bennett Supervisor Research Associate Royal British Columbia Museum Staffan Lindgren Internal Examiner Professor Emeritus University of Northern British Columbia Damian O. Elias External Examiner Associate Professor Department of Environmental Science, Policy and Management University of California, Berkeley Date Defended/Approved: August 15, 2016 ii Abstract Spiders provide a fascinating opportunity for the study of animal communication. Web- building spiders build their own signalling environments - the web is the medium that transmits vibrations from prey, predators and potential mates. However, we know little about how information is conveyed through different types of webs, or how spiders distinguish between different types of vibrations. In this thesis, I studied elements of vibratory communication in two species of spiders with contrasting web architecture: the western black widow, Latrodectus hesperus, which builds a tangle-web, and the hobo spider, Eratigena agrestis, which builds a funnel-web. In chapter 2, I document formerly undescribed life history traits of E. agrestis, and conclude that life history traits are robust to differential predator and competitor densities across two study sites in British Columbia. -

There are tales describing how they lay eggs in human skin, frequent toilet seats in airports, and crawl into your mouth when you are sleeping. Misinformation about spiders in the popular media and on the World Wide Web is rampant, leading to distorted perceptions and negative feelings about spiders. Despite these negative feelings, however, spiders offer intrigue and mystery and can be used to effectively engage even arachnophobic individuals.
