Abstract:

This paper makes a faunistic contribution to knowledge of the spider family composition in the experimental research plots of Kasetsart University in Thailand (Kampaeng Saen Campus, Nakhon Pathom province). Spider families were investigated both on the foliage and on the ground in physic nut plantations (Jatropha curcas L.). Ground dwelling spiders were collected by pitfall traps while foliage spiders were sampled by sweeping and hand collecting. In total, 655 spider specimens were collected and identified as belonging to 17 families. The dominant ground dwelling spider families were Lycosidae

Abstract:

The investigation dealt with the epigeic spider fauna of a fen area in north-eastern Iceland. The mires in question consisted of a mosaic of subparts differing in ground moisture and vegetation. The aim of the study was to determine whether the spider communities differed correspondingly. Pitfall trapping, vegetation mapping and ground moisture estimation were carried out at 11 different sites. 7958 adult spider individuals belonging to 41 species collected. The study sites varied more in abundance of the spiders than in species composition. Grouping of spider species according to their main o

Abstract:

Abstract Fire is a natural disturbance that occurs in many temperate and tropical ecosystems worldwide. As ubiquitous members of these ecosystems, spiders (Araneae) are often affected by fire, and their response to this disturbance has been shown to be dependent on taxonomy, functional diversity, seasonality, and a variety of environmental factors. We examined the effect of fire on ground-dwelling spider assemblages in temperate forests in central Indiana over 5 yr and found that spider assemblages were significantly affected by fire disturbance. Overall spider abundance decreased, whereas spe

A total of 2935 individuals from 95 spider species were identified. Catch rates for hunting spiders were significantly higher in the clear-cut stands than in the burned stands, but between-stand species turnover of hunting spiders was twice as high in the burned stands as in the clear-cut stands.

Abstract: Arthropod distributions across riparian gradients remain incompletely understood. Within riparian buffers, invasive plants such as Fallopia japonica (Japanese knotweed) may influence abiotic conditions and potentially arthropod distributions. We quantified ground spider and ground beetle activity across a Japanese knotweed-dominated riparian buffer using five months of pitfall trapping data. Results from pitfall samples suggest that spider and beetle activity is negatively correlated with the presence of Japanese knotweed along the riparian gradient. We found that beetle activity dec

Abstract:

Spiders have important ecological roles as generalist predators, are a significant source of food for many other species, and are bioindicators of environmental health. However, spiders are poorly studied. Given their importance, a comparison of spider survey methods used to determine differences in spider diversity and abundance is required to understand their limitations and biases. A new survey method to attract spiders, based on vibration from an idling diesel tractor, was tested and compared to the traditional methods of pitfall trapping and hand collection of spiders at night.

Abstract:

Introduction: Accidents involving spiders bites usually cause mild medical reactions that lead to local symptoms and, less commonly, systemic effects. The most medically significant spiders belong to the genera Latrodectus and Loxosceles. This paper presents a posible case of steatodism in a young woman and her pet.Case description: 26-year-old female patient, who reports a clinical history characterized by paresthesia, malaise, fever, diarrea and a painful papule in the left cheek after being bitten by a spider. Immediately after being bit, the patient hit the spider with the back of her hand

Abstract:

The present investigation is a very first attempt to generate the checklist of spiders from Chandranath Hill, Paroda, Quepem, Goa. A preliminary study was conducted from June 2018 to March 2020 to document the spider diversity from the region. In all, 125 species of spiders belonging to 102 genera from 19 families were identified. The dominant families were Salticidae followed by Araneidae. Guild structure analysis revealed six feeding guilds, namely, orb weavers, foliage runners, ground runners, stalkers, space-web builders and ambushers.

Survey of the spider fauna was carried out for a period of twelve months. In total, 3286 individuals were collected from the sanctuary, which consist of 89 species of spiders under 59 genera and 18 families. Araneidae was the most abundant family. The most abundant species was Hippasa agelenoides of Lycosidae family. Spiders belonging to six feeding guilds, i.e., orb -

Abstract:

Green roofs are valuable ecosystems that enhance the biodiversity value of urban landscapes in northern Alberta. Using pitfall traps on green roofs and adjacent ground sites, we show that roof arthropods are characteristic of native grasslands that are threatened in Alberta. Although we found lower abundance of spiders and carabids on roofs, species richness as assessed by rarefaction did not differ between roof and nearby ground sites. Thus, arthropod communities of these extensive green roofs do not seem to be impoverished compared to ground habitats, despite differences in local environment

Fire supports landscape openness; thus, prescribed burning could be an effective management in open landscapes. In this study we tested the response of arthropods (spider, ground beetle, rove beetle and woodlouse) to dormant-season prescribed burning in dry grassland patches. We hypothesized that the unburned patches support the arthropods recolonizing the burned patches; thus, fire causes no serious damage to the arthropod assemblages. Epigeic arthropods (spider, ground beetle, rove beetle and woodlouse) were collected by unbaited pitfall traps containing ethylene glycol as a killing-preservi

Spiders (Order Araneae) are massively abundant generalist arthropod predators that are found in nearly every ecosystem on the planet and have persisted for over 380 million years. Spiders have long served as evolutionary models for studying complex mating and web spinning behaviors, key innovation and adaptive radiation hypotheses, and have been inspiration for important theories like sexual selection by female choice. Unfortunately, past major attempts to reconstruct spider phylogeny typically employing the “usual suspect” genes have been unable to produce a well-supported phylogenetic framew

Spider web silk decorations may (i) act to attract prey, (ii) be decoys for predators, and (iii) make the web visible to prevent larger animals from destroying them. To disentangle the last two hypotheses, we examined the fleeing response and flight initiation distance (FID) of the Florida orb weaver spider (Argiope florida Chamberlin and Ivie, 1944). Spiders were approached in one of two manners: (1) a “predatory” one mimicking a bird and (2) a “looming” approach mimicking the approach of a large animal.
