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. -

In Chile, all necrotic arachnidism is attributed to the Chilean recluse spider Loxosceles laeta (Nicolet) (Araneae: Sicariidae). It is predated by the spitting spider Scytodes globula (Nicolet) (Araneae: Scytodidae). The biology of each of these species is not well known and it is important to clarify their distributions. The aims of this study are to elucidate the variables involved in the niches of both species based on environmental and human footprint variables, and to construct geographic maps that will be useful in estimating potential distributions and in defining a map of estimated risk for loxoscelism in Chile. Loxosceles laeta was found to be associated with high temperatures and low rates of precipitation, whereas although S. globula was also associated with high temperatures, its distribution was associated with a higher level of precipitation. The main variable associated with the distribution of L. -

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. -

Los ecosistemas urbanos son aquellos defi nidos como ambientes dominados por el hombre. Con el proceso de urbanización, insectos y arácnidos silvestres aprovechan los nuevos microhábitats que las viviendas humanas ofrecen. Se revisaron arañas recolectadas dentro de 109 viviendas durante los años de 1985 a 1986, 1996 a 2001 y 2002 a 2003. Se cuantifi caron 1 196 organismos , los cuales se determinaron hasta especie. Se obtuvo una lista de 25 familias, 52 géneros y 63 especies de arañas sinantrópicas. Se utilizaron 3 índices (ocupación, densidad y estacionalidad) y un análisis de intervalos para sustentar la siguiente clasifi cación: accidentales (índice de densidad de 0-0.9), ocasionales (1-2.9), frecuentes (3.0-9.9) y comunes (10 en adelante). Se comparan las faunas de arañas sinantrópicas de 5 países del Nuevo Mundo. Palabras clave: sinantropismo, ecología, urbanización, microhábitats. Abstract. Urban ecology is a relatively new area of research, with urban ecosystems being defi ned as environments dominated by humans. Insects and arachnids are 2 groups that successfully exploit the habitats offered by human habitations. -

These impose three main problems: (i) terrestrial habitats have large fluctuations in temperature and humidity; (ii) the internal concentration of water is higher than the external environment in spiders, which exposes them continually to water loss; and (iii) their small body size determines a large surface/volume ratio, affecting energy exchange and influencing the life strategy. In this review we focus on body design, energetic, thermal selection, and water balance characteristics of some spider species present in Chile and correlate Edited by: our results with ecological and behavioral information.

LABARQUE1 & MARTÍN J. RAMÍREZ1 1Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Av. Ángel Gallardo 470, C1405DJR, Buenos Aires, Argentina. [email protected] / [email protected] Abstract The relationships of Scytodoidea, including the families Drymusidae, Periegopidae, Scytodidae and Sicariidae, have been con- tentious for a long time. Here we present a reviewed phylogenetic analysis of scytodoid spiders, emphasizing Periegops, the only genus in the family Periegopidae. In our analysis the Scytodoidea are united by the fusion of the third abdominal entapo- physes into a median lobe, the presence of female palpal femoral thorns and associated cheliceral stridulatory ridges, a mem- branous lobe on the cheliceral promargin, and the loss of minor ampullate gland spigots. A basal split within Scytodoidea defines two monophyletic groups: Sicariidae and a group formed by Scytodidae as the sister group of Periegopidae plus Dry- musidae, all united by having bipectinate prolateral claws on tarsi I–II, one major ampullate spigot accompanied by a nubbin, and the posterior median spinnerets with a mesal field of spicules. Periegops is the sister group of Drymusidae, united by the regain of promarginal cheliceral teeth and a triangular cheliceral lamina, which is continuous with the paturon margin. Key words: Drymusa, Drymusidae, Haplogyne, morphology, Scytodes, Stedocys, Scytodidae, Sicariidae, Sicarius, Loxosceles Introduction The family Periegopidae currently comprises only the genus Periegops, with two species: the type species Perie- gops suteri (Urquhart) from the Banks Peninsula on the South Island of New Zealand (Vink 2006), and Periegops australia Forster, from southeastern Queensland (Forster 1995).
