“…The leaf-litter complexity affects the spider assemblages [37] [59]; a study conducted in a deciduous forest revealed that spiders are stratified distributed on leaf-litter [60]. Thus, a thicker leaf-litter on forest formations offers spiders' greater refuge and prey availability [35] [59]; favoring vertical distribution [60], and thus reducing competition.…”

“…In tropical forests such as any other natural landscape, habitat structure influences the richness and composition of spider's assemblages species [34]). Leaf litter structure also affects spiders' abundance [35], richness and composition [36] [37]. Therefore, natural disturbance caused by tree fall gaps may also influence the spider's assemblages [38] [39].…”

The study investigates the effect of spatial and temporal tree-fall gaps structure on spiders' assemblage in an Atlantic forest fragmented area in Brazil. It was conducted in the Michelin Ecological Preserve-REM (Bahia), 190 ha forest remnant. Samples were collected on leaf-litter (50 × 50 cm) at five tree-fall gaps formations (<150 m 2), within five adjacent primary forest and five inner edge parcels. During 16 months (between May 2009 and October 2012), 480 m 2 leaf-litter samples were collected, from which spiders were extracted using mini-Winkler traps. The observed and estimated richness of spider's species was higher at the edge (p < 0.01). The habitat structures differ significantly among the three habitat types (MRPP, p < 0.01) and also during the tree-fall gaps aging gradient (MRBP, p < 0.01). There were significant differences on spiders' species composition, comparing the three habitats (MRPP, p < 0.05). The composition of spider's species changed as tree-fall gaps aged (MRBP, p < 0.05). We argue that the tree-fall gaps play, on a local scale, an important role in acting on the time-space distribution dynamics of spider's species assemblages, although the time effect should still be evaluated.

We present an ant and spider species list from five localities of the Metropolitan Region of Salvador (MRS). The MRS is placed in an Atlantic Forest area classified as dense broadleaf forest, considered to be of high biological importance and priority for conservation. We determined 198 species of ants (8 of these are considered to be synanthropic and/or exotic), distributed across nine subfamilies. We determined 164 species of spiders (14 of them being synanthropic and/or exotic), distributed across thirty families. Therefore, this survey shows that the urban environment of the MRS still harbors a large number of native fauna species.
