Diversity of Spiders from Zolambi Region of Chandoli National Park
IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) e-ISSN: 2278-3008, p-ISSN:2319-7676. Volume 10, Issue 2 Ver. 1 (Mar -Apr. 2015), PP 30-33 www.iosrjournals.org Diversity of Spiders from Zolambi Region of Chandoli National Park Dr. Suvarna More Dept. of Zoology P. V. P. Mahavidyalaya, Kavathe Mahankal, Dist. -Sangli. (MS), India 416405 Abstract: Diversity of spiders from Zolambi region of Chandoli National Park in Western Ghats is studied for the first time. A total of 90 species belonging to 55 genera and 19 families are recorded from the study area during 2011-2013 with a dominance of Araneid, Salticid and Lycosid spiders. Key words: Spider diversity, Western Ghats I. Introduction Spiders comprise one of the largest orders of animals. The spider fauna of India has never been studied in its entirety despite of contributions by many arachnologists since Stoliczka (1869). The pioneering contribution on the taxonomy of Indian spiders is that of European arachnologist Stoliczka (1869). Review of available literature reveals that the earliest contribution by Blackwall (1867); Karsch (1873); Simon (1887); Thorell (1895) and Pocock (1900) were the pioneer workers of Indian spiders. They described many species from India. Tikader (1980, 1982), Tikader, described spiders from India. Tikader (1980) compiled a book on Thomisidae spiders of India, comprising two subfamilies, 25 genera and 115 species. Pocock (1900) and Tikader (1980, 1987) made major contributions to the Indian Arachnology, have high lightened spider studies to the notice of other researcher. Tikader (1987) also published the first comprehensive list of Indian spiders, which included 1067 species belonging to 249 genera in 43 families. -

Journal of Entomology and Zoology Studies 2019; 7(4): 1432-1439 E-ISSN: 2320-7078 P-ISSN: 2349-6800 Diversity of common garden and house spider in JEZS 2019; 7(4): 1432-1439 © 2019 JEZS Tinsukia district Received: 01-05-2019 Accepted: 05-06-2019 Achal Kumari Pandit Achal Kumari Pandit Graduated from Department of Zoology Digboi College, Assam, Abstract India A study on the diversity of spider fauna inside the Garden and House in Tinsukia district, Assam. 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. -

Comparison of the Recent and Miocene Hispaniolan Spider Faunas
ARTÍCULO: COMPARISON OF THE RECENT AND MIOCENE HISPANIOLAN SPIDER FAUNAS David Penney & Daniel E. Pérez-Gelabert Abstract Hispaniolan (=Dominican Republic and Haiti) araneology is reviewed and a checklist of fossil (Miocene Dominican Republic amber) and Recent spiders is provided, with type data and recorder details for endemic taxa. The fossil fauna consists of 145 described species in 35 families and the Recent fauna, 296 species in 40 families. Twenty-nine families and 28 genera are shared, representing similarity values of 63.0% and 13.0% respectively. If the records for additional families (9) and genera (9) without formal species described are added, then these values become 68.0% and 15.5% respectively. No strictly fossil families are known, 25 genera are exclusively fossil and all species from the amber are extinct. The diversity (Shannon index) and evenness of species within ARTÍCULO: families is not significantly different between the faunas. Distinct similarities are observed between the fossil and Recent faunas in genus and species numbers for the Comparison of the Recent and families Pholcidae, Theridiidae and Corinnidae; dissimilarities are observed in Miocene Hispaniolan Spider Tetragnathidae, Araneidae and Salticidae. We consider the Recent fauna to be poorly faunas known and worthy of further investigation, particularly because of its potential, when compared with the fossil fauna, to address palaeoecological problems.

We carried out five surveys of the caves, with each cave divided into sampling plots. We collected fauna within the plots using a manual search method. The collected animals were fixed in 70% ethanol for later identification. We performed a canonical corre- spondence analysis to verify the spatial distribution and substrate preference of each species, and selected five species for agonistic interaction testing in the laboratory. We found a great richness of predators in the caves, with 79 species distributed among 22 families of spiders, five families of pseudoscorpions, three families of chilopods, two families of opilionids and one family each of scorpions and heteroptera. -

Correspondencia: [email protected] 22 Parasitología Latinoamericana. (2015); 64 (1): 22- 29 Revista Parasitología Latinoamericana Summary Loxoscelism is a health problem caused by the bite of spiders of the genus Loxosceles (Araneae: Sicariidae). In Chile, all necrotic arachnidism is attributed to the Chilean recluse spider, L. laeta, a species that may be preyed upon by the spitting spider Scytodes globula Nicolet (Araneae: Scytodidae). The first approximation to the risk of loxoscelism is based on the knowledge of the species distribution but although L. laeta and S. globula are very common in central Chile and are synanthropic spiders, the distribution of these species is not well known. In this study based on previous estimations of preferred temperatures of L. laeta and S. globula we estimate the potential distribution of these species and compare with the actual reported presence data. We found that the best predictor was the average temperature. The maps of temperature-based potential distribution of L.laeta had a good goodness of fit to presence data. -
