Haddad1 As part of the South African National Survey of Arachnida (SANSA) in conserved areas, arachnids Ansie S. Dippenaar- were collected in the De Hoop Nature Reserve in the Western Cape Province, South Africa. The Schoeman2 survey was carried out between 1999 and 2007, and consisted of five intensive surveys between Affiliations: two and 12 days in duration. Arachnids were sampled in five broad habitat types, namely fynbos, 1Department of Zoology & wetlands, i.e. De Hoop Vlei, Eucalyptus plantations at Potberg and Cupido’s Kraal, coastal dunes Entomology University of near Koppie Alleen and the intertidal zone at Koppie Alleen. A total of 274 species representing the Free State, five orders, 65 families and 191 determined genera were collected, of which spiders (Araneae) South Africa were the dominant taxon (252 spp., 174 genera, 53 families).

A Protocol for Online Documentation of Spider Biodiversity Inventories Applied to a Mexican Tropical Wet Forest (Araneae, Araneomorphae)

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. -
Seasonal Abundance and Diversity O F Web-Building Spiders in Relation to Habita T Structure on Barro Colorado Island, Panama
Lubin, Y . D. 1978 . Seasonal abundance and diversity of web-building spiders in relation to habita t structure on Barro Colorado Island, Panama . J. Arachnol. 6 :31-51 . SEASONAL ABUNDANCE AND DIVERSITY O F WEB-BUILDING SPIDERS IN RELATION TO HABITA T STRUCTURE ON BARRO COLORADO ISLAND, PANAMA Yael D . Lubin Smithsonian Tropical Research Institute P. O. Box 2072, Balboa, Canal Zone ABSTRAC T Web-building spiders were censused by a visual censuring method in tropical forest understory o n Barro Colorado Island (BCI), Panama Canal Zone. An overall trend of low numbers of spiders in th e late dry season and early wet season (March to May) was seen on all transects . The majority of th e species on the transects had wet season distribution patterns . Some species which occurred year-round on the forest transects had wet season distributions on a clearing-edge transect . A shortage of flyin g insect prey or dessication may have been responsible for the observed distributions . Species diversity and diversity of web types followed the overall seasonal pattern of spider abun- dance. The diversities of species and of web types were greatest on the forest transect with the highes t diversity of structural supports for spider webs . Web density, however, was greatest on the transect a t the edge of a small clearing . Faunal composition, diversity of web types, and seasonal patterns of distribution of spiders on th e BCI transects differed markedly from similar measures derived from censuses taken in a tropica l montane habitat in New Guinea . The differences were attributed in part to differences in the habitat s and in the evenness of the climate . -

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 total of 55 species belonging to 36 genera and 13 families are sampled. Newly recorded taxa include four genera and 11 species of Araneidae, six genera of Araneidae, each represented by single species. The species recorded under Tylorida Simon and Tetragnatha Latreille of Tetragnathidae and Camaricus Thorell and Thomisus Walckenaer of Thomisidae are found to be new from the state. Also, three oxyopids and one miagrammopid are new. So far, Linyphiidae, Pisauridae, Sparassidae and Theridiidae were unknown from the state. Out of 55 species, 13 are endemic to India and thus exhibiting a high endemicity (23.6%). A family key of the State Fauna is provided along with relevant images of the newly recorded species.

What Is the Diversity of Sub-Canopy Web Building Spiders in Three Separate Regions of Puerto Rico?
Cantaurus, Vol. 23, 21-27, May 2015 © McPherson College Department of Natural Science What is the Diversity of Sub-Canopy Web Building Spiders in Three Separate Regions of Puerto Rico? Nathaniel D. Schowengerdt ABSTRACT Understanding the many aspects of the biodiversity of our planet yields many positive advancements in the conservation and maintenance of its current and future states. This experiment seeks to explore the more intricate facets of this by sampling and comparing the diversity of web building spider species in three separate areas of the island of Puerto Rico. The island is known for its diversity, despite its relatively small size, about 100 by 35 miles. Ecosystems vary from temperate moist forests, to rainforest, to desert and dry forest, just within that space. Several methods of sampling were attempted and evaluated for their efficiency in each environment, but due to difficulties with some methods and a need for standardization for comparisons, only the visual sampling technique was deemed as successful in this case. Specimens were identified down to the classifications of family and genus through identification of morphological structures, as well as other defining traits. After identification, relationships and comparisons were made within and between the areas, and further analysis using Simpson’s Index and Community Similarity Index was utilized. It was determined that based off of this collection, the Guanica site housed the greatest diversity in specimens, although there were several similar specimens found in all three of the areas. This may imply the distribution of some types of spiders may be affected by ecological factors that differ in each of the areas, such as resource and habitat availability. -
