“…Pitfall trapping has limited value in providing absolute estimates of spider abundance, as the capture efficiency is affected by factors including abundance and activity of individual species (Topping and Sunderland 1992;Holland and Smith 1999), vegetation density (Melbourne 1999), trap size (Work et al 2002) and trampling by large mammals (Oxbrough et al 2006). Consequently, some taxa can be overestimated while other taxa can be underestimated (Lang 2000).…”

Effects of a fast-burning spring fire on the ground-dwelling spider assemblages (Arachnida: Araneae) in a central South African grassland habitat

Fire is widely used as a management strategy in grasslands to maintain vegetation structure and improve grazing quality for large herbivores. The impacts of burning on invertebrates in South Africa remain poorly understood. A study was initiated in spring 2005 to determine the impact of a fast hot burn on ground-dwelling spider assemblages in a grassland habitat in the central Free State. Pitfall traps were set out at six sites in the reserve, with three sites each in the burnt and unburnt areas, to sample spiders over a 12-month period. A total of 5 253 spiders were collected, representing 33 families and 120 species. Spider abundance was significantly lower in the burnt (n = 1 956) than unburnt sites (n = 3 297), and burnt sites had, on average, considerably fewer species than unburnt sites. The dominant families in the burnt sites were Lycosidae (29.5%), Gnaphosidae (16.9%), Ammoxenidae (9.6%) and Zodariidae (5.7%), whereas Ammoxenidae (22.7%), Lycosidae (20.6%), Gnaphosidae (15.3%) and Amaurobiidae (10.2%) dominated the unburnt sites. Of the nine most abundant families collected, only Caponiidae were more abundant in the burnt than unburnt sites. Our data suggest that fast-burning hot spring fires cause a considerable initial post-fire decline in spider abundance, and have a negative influence on the abundance as well as the resistance of assemblages to disturbances other than fire (e.g. rain). However, most of the dominant families had abundances comparable to unburnt areas within a year post-burn.

“…The tubs were sealed with lids when not in use. The trap size selected is unlikely to capture rare or large invertebrates but acceptably characterizes the dominant fauna active within the ground layer without mammalian and amphibian by-catch (Work et al 2002).…”

Local and landscape drivers of arthropod abundance, richness, and trophic composition in urban habitats

et al. 2013

Urban green spaces, such as forest fragments, vacant lots, and community gardens, are increasingly highlighted as biodiversity refuges and are of growing interest to conservation. At the same time, the burgeoning urban garden movement partially seeks to ameliorate problems of food security. Arthropods link these two issues (conservation and food security) given their abundance, diversity, and role as providers of ecosystem services like pollination and pest control. Many previous studies of urban arthropods focused on a Author's personal copy single taxon (e.g. order or family), and examined either local habitat drivers or effects of landscape characteristics. In contrast, we examined both local and landscape drivers of community patterns, and examined differences in abundance, richness, and trophic structure of arthropod communities in urban forest fragments, vacant lots, and community gardens. We sampled ground-foraging arthropods, collected data on 24 local habitat features (e.g., vegetation, ground cover, concrete), and examined land-cover types within 2 km of 12 study sites in Toledo, Ohio. We found that abundance and richness of urban arthropods differed by habitat type and that richness of ants and spiders, in particular, varied among lots, gardens, and forests. Several local and landscape factors correlated with changes in abundance, richness, and trophic composition of arthropods, and different factors were important for specific arthropod groups. Overwhelmingly, local factors were the predominant (80 % of interactions) driver of arthropods in this urban environment. These results indicate that park managers and gardeners alike may be able to manage forests and gardens to promote biodiversity of desired organisms and potentially improve ecosystem services within the urban landscape.

“…En primer lugar, las trampas de intercepción están principalmente dirigidas al ensamble de artrópodos caminadores (Greenslade 1964, Jensen & Mestz 1977, de los Santos et al 1982, Cepeda-Pizarro 1987, Southwood 1994, Péfaur & Díaz 2000, de los Santos et al 2000, Work et al 2002, Koivula et al 2003; aun cuando se reconoce que en ecosistemas desérticos se puede lograr con ellas capturas representativas de especies de insectos voladores y fitófagos (Pietruszka 1980). En segundo lugar, la eficiencia de las trampas depende tanto del efecto que tienen algunas variables atmosféricas sobre la actividad de los individuos (e.g., temperatura del aire), como de la presencia de barreras que limiten su libre desplazamiento (e.g., mantillo herbáceo u orgánico) (Greenslade 1964, Gist & Crossley 1973, Hinds & Rickard 1973, Adis 1979.…”
