Main habitat characteristics (mean±standard error) of tank-bromeliad species found in five vegetation types.
Figure 2.
Examples of connectance webs under two contrasted environmental conditions: open areas (A, B) and forest areas (C, D).
The upper trophic level (predators) is at the top of the graphs, and the lower (algae, detritus) at the bottom. Numbers and abbreviations are for: Wyeomyia spp. (1; filter-feeder); Culex spp. (2; filter-feeder); Forcypomiinae sp2 (6; filter-feeder); Bezzia sp. (7; predator); Tanypodinae (9; predator); Chironominae (10; detritivore); Tanytarsinii (11; detritivore); Corethrella sp. (12; predator); Telmatoscopus sp1 (14; detritivore); Limoniinae (17; detritivore-shredder); Cyphon sp. (22; shredder); Coenagrionidae (24; predator); Aulophorus superterrenus (25; detritivore); Hydracarina (28; detritivore); Elpidium sp. (34; detritivore-scraper); Bacteria (I); Cyanobacteria (II); Fungi (III); Algae (IV); Flagellate (V); Ciliate (VI); Rotifera (VII); Fine Particulate Organic Matter (FPOM).
