“…MC comparados à área de cultivo do cafeeiro (CA) (Figura 2 e Tabela 3). As famílias de aranhas são afetadas pelo tipo de uso e manejo do solo, sendo mais abundantes em locais com menor intervenção humana, como relata o estudo deRosa et al (2019). Esses autores encontraram maior abundância de famílias de aranhas em áreas de floresta nativa, comparando-as com áreas de reflorestamento de eucalipto, integração lavoura-pecuária, plantio direto, pastagem e plantio convencional.…”

The reduction of natural forest cover, mostly due to the competition with the agricultural activity, as well as its low conservation level, can diminish the diversity of the soil fauna organisms, which act in the decomposition of organic matter and nutrient cycling, for example, key functions for maintaining soil quality. Thus, the objective of this study was to verify the potential of edaphic fauna as a bioindicator of soil and / or environmental quality in Secondary Semideciduous Seasonal Forest (MC), Regenerating Semideciduous Seasonal Forest (MI) and coffee growing area (CA). Soil invertebrates were collected by the TSBF methodology, in which 10 soil monoliths (25 x 25 cm and 0-20 cm profundity) were retired from each area, 30 m apart. At the same collection points, the litter was sampled and 10 fall traps were installed, which remained buried in the ground for three days. Soil was collected for chemical attributes analysis and soil moisture, and litter. Considering the TSBF methodology the highest density (m2) of edaphic organisms was observed in the MC area, differing statistically from CA. For the fall traps the highest abundance was found in the MI area, without

“…Similarly, the Principal component analysis method was used by Rosa et al (2019) to study the diversity of soil spiders in land use and management systems in Santa Catarina, Brazil and evaluate the habitat specific occurrence of spider in native forest, eucalyptus reforestation, pasture, crop-livestock integration, and no-tillage crop. Schuldt et al (2008) also used PCA to analyse ground-living communities of spiders in deciduous forests with relationship between spider diversity and ecosystem function in Thuringia.…”

Spiders are the Arthropod and belong to the Phylum: Arthropoda, Class: Arachnida, Order: Araneae. Spiders totally depend on predation of small insects and other animals and have important role in the structure of communities and food webs both as an individual numbers and as an energy consumer.. Hence, documentation of spiders gives information about biodiversity of ecosystem in a particular geographical area. Totally arthropods belonged to 14 orders and 85 Nos. of different families. To study the similarity between two groups in species, family and ordinal level is used Agglomerative Hierarchical Clustering (AHC). Principal Component Analysis (PCA) and Correspondence Analysis (CA) were evaluated to understand the arthropod population dynamics and habitat specific occurrence of spiders in different ecosystem Viz., Silvicultural, Horticultural and Agricultural ecosystem. To correlate the weather parameters with spider population we used Pearson correlation, regression line, Redundancy Analysis (RDA) and Canonical Coefficient Analysis (CCA). Correlation analysis showed arthropod population positively correlated to maximum and minimum temperature and evening relative humidity and negatively correlated to morning relative humidity and rainfall. The eigenvectors at generic level was found maximum in horticultural ecosystem (0.591) followed by silvicultural (0.581), maize (0.407), rice (0.329) and potato ecosystem (0.183) in factor (F1). The asymmetric CA row and column plot in generic level suggested that the genus Tylorida,, potato and horticultural ecosystems respectively. In case of weather perimeter with relation to arthropod population RDA showed that Arachnids families viz., Lycosidae, Thomisidae, Theridiidae, Tetraganthidae etc are closely associated with maximum temperature in silvicultural and horticultural ecosystems.

“…The presence of spiders in certain habitats is often associated with the structural quality of ecosystems, due to the biological control effect exerted by these arachnids on different invertebrate populations (Silva & Coddington 1996, Rosa et al 2019. Because most spiders are predators, it is believed that their richness and abundance reflect the richness and abundance of other arthropods belonging to lower trophic levels in the same environment (Nogueira et al 2006).…”

Ground spiders (Arachnida, Araneae) associated with urban forest fragments in southern Amazon

Forest fragments in urban areas comprise important habitats for a wide variety of species, however, conservationist policies for their maintenance and conservation are still incipient. This study examined the richness and abundance of the ground-spider assemblage in five forest fragments, with areas ranging between 18.5 and 103.98 ha, in the urban perimeter of Sinop, northern Mato Grosso State, southern Amazon region of Brazil. Sampling was carried out using the mini-Winkler extractor and pitfall traps in the dry (July) and rainy (November) seasons of 2017. All fragments were characterized in relation to the area and the Index of Biotic Integrity (IBI), to assess the effect of these variables on richness and abundance of soil spider assemblage. A total of 653 spiders were sampled, corresponding to 25 families and 52 species. Salticidae, Theridiidae, Lycosidae, Linyphiidae, Oonopidae and Symphytognathidae were the most abundant families (63.3% of the total sample). The assemblage was characterized by the dominance of hunting spiders (393 ind.; 60.2%) over web-building spiders (260 ind.; 39.8%). Greater spider abundance and richness was obtained during the rainy season (517 ind.; 79.2%; 41 spp.) as compared with the dry season (136 ind.; 20.8%; 24 spp.). Only 13 species occurred in dry and rainy season. Two species were recorded for the first time in the Amazon region, namely, Anapistula aquytabueraRheims & Brescovit, 2003 (Symphytognathidae) and Opopaea concolor (Blackwall, 1859) (Oonopidae). Species richness was not affected by IBI and area of fragment. Although the statistical model is not significant, species richness increases slightly with IBI and area of fragment. Similarly, abundance of spiders was not affected by IBI and area of fragment. Regardless of the area size, all evaluated forest fragments showed a low and regular IBI, demonstrating that these habitats have suffered with the pressures inherent from the urban perimeter, including the constant expansion of human occupation as well as misuse by the population. Nonetheless, these same fragments revealed considerable richness of species of ground spiders and can thus be categorized as important habitats for the maintenance of regional biodiversity. Therefore, action strategies must be set out to ensure their conservation.
