The role of spider hunting mode on the strength of spider–plant mutualisms
(2018-09-01)
The strength and outcome of mutualistic interactions can be highly dependent on the combination of traits of the species involved. Distinct foraging strategies (e.g., hunting mode) of mutualistic predators may cause ...
Effect of architectural angularity on refugia selection by the brown spider, Loxosceles gaucho
(Wiley-Blackwell, 2010-09-01)
Some brown spider species infest man-made environments and pose a threat to human health. Because habitat architecture affects spider populations, I evaluated the preferences of individuals of Loxosceles gaucho (Gertsch) ...
Distribution of plant-dwelling spiders: Inflorescences versus vegetative branches
(Blackwell Publishing AsiaCarltonAustralia, 2004)
Mantispa minuta Fabricius (Neuroptera : Mantispidae) on egg sacs of the orb-weaver spider Parawixia bistriata (Araneidae) in forests of Eucalyptus grandis in Brazil
(Swets Zeitlinger Publishers, 2002-08-01)
This is the first report of the interaction between the two entomophagous agents Mantispa minuta Fabricius (Mantispidae) and Parawixia bistriata Rengger, an orb-weaver spider (Araneidae). From egg sacs kept in the laboratory ...
Bromeliads provide shelter against fire to mutualistic spiders in a fire-prone landscape
(Wiley-Blackwell, 2018-06-01)
1. A key challenge in the study of mutualistic interactions is understanding sources of variation that strengthen or weaken these interactions. In spider-plant mutualisms, spiders benefit plants by improving plant nutrition ...
Distribution and importance of spiders inhabiting a Brazilian sugar cane plantation
(Sociedade Brasileira de Zoologia, 2002-07-01)
The spider fauna (Araneae) of a sugar eane plantation was surveyed monthly by hand colteetion and beating vegetation in sugar cane fields across Botucatu, State of São Paulo, Brazil. Composition and rchness (family and ...
The effect of hunger level on predation dynamics in the spider Nesticodes rufipes: a functional response study
(Springer, 2006-09-01)
It is well known that a predator has the potential to regulate a prey population only if the predator responds to increases in prey density and inflicts greater mortality rates. Predators may cause such density-dependent ...
Bromeliad-living spiders improve host plant nutrition and growth
(Ecological Soc Amer, 2006-04-01)
Although bromeliads are believed to obtain nutrients from debris deposited by animals in their rosettes, there is little evidence to support this assumption. Using stable isotope methods, we found that the Neotropical ...
Isolation and chemical characterization of PwTx-II: A novel alkaloid toxin from the venom of the spider Parawixia bistriata (Araneidae, Araneae)
(Elsevier B.V., 2005-12-01)
Brazil has many species of spiders belonging to Araneidae family however, very little is known about the composition, chemical structure and mechanisms of action of the main venom components of these spiders. The main ...
