Description:
The wolf spider (Lycosidae) community of open paddocks and five different configurations of woodland habitat in the wheatbelt of New South Wales, Australia, was sampled by nocturnal spotlighting. A total of 16 species was detected amongst the 2769 individuals that were sufficiently mature to allow identification, and 80% of these individuals were accounted for by just three species. There were no significant differences in the spider community among any of the woodland configurations, but the community of all five configurations differed significantly from that of open paddocks. However, only three species differed significantly in abundance between paddocks and the woodland configurations. Two species, Venator spenceri and Sp. C appeared to be less common in paddocks than in the woodland habitats, while Sp. A was more abundant in the paddocks. The percentage cover of thistles, medium grass and high grass, as well as the total abundance of Callitris glaucophylla were the habitat variables that best explained variation in the wolf spider community between woodland sites. Of these, thistle cover had the strongest correlation suggesting that disturbance, rather than cover per se, might be an important determinant of wolf spider communities. This study indicates that habitat fragmentation, at the spatial scale associated with current agricultural practices, may not be presenting a threat to generalist ground predators such as wolf spiders.

Description:
Ballooning is a form of aerial movement practiced by most immature and some adult spiders. Very few studies have investigated the composition and rate of spider ballooning in Australian agroecosystems. Water traps were used to compare ballooning rates in irrigated soybean crops and nearby non-crop areas in southeast Queensland over two summer seasons. The highest ballooning rate (14.8spiders/m^2 per day) was recorded in a soybean field, non-crop areas (7.0spiders/m^2 per day) and a dry land mungbean field (6.8spiders/m^2 per day) having similar rates. Spider ballooning in soybean increased throughout the season and showed three peaks and intervening troughs. A similar pattern in ballooning peaks was observed in non-crop areas however the numbers were lower. Peaks in ballooning activity where synchronised across habitat types and some spider groups. Composition of the ballooning fauna was different from that of the ground-dwelling fauna, some families being present in both. Ballooning is an important behaviour in terms of population dynamics for a number of spider groups in soybean and the implications for pest control are discussed.
