Besides the litter layer, natural microhabitats on the soil surface like rocks and coarse wood
debris are important elements that determine habitat heterogeneity. Knowledge about how
invertebrate communities relate to these elements is fundamental to the conservation of species
and ecosystems. We investigate the colonization pattern of artificial shelters by terrestrial isopods
in relation to seasonality and presence of other invertebrates. The importance of sheltering to
isopods was investigated taking into account reproduction, life strategies and susceptibility to
desiccation of two Neotropical species: Atlantoscia floridana (Philosciidae) and Balloniscus
glaber (Balloniscidae). These species are commonly syntopic and often show a high species
association (Quadros & Araujo, 2008). We predict that (1) Shelter use should be more important
to A. floridana - which is a typical surface-litter dwelling isopod - than to B. glaber, which shows
an increased burrowing ability; (2) Intensity of sheltering should increase in summer, specially in
the case of A. floridana which is more susceptible to desiccation, (3) Abundance of reproductive
females should be higher under shelters than in the adjacent litter and (4) Distribution of isopods
under shelters is not random and may be influenced by other invertebrates. The experiments
were conducted during one year in a secondary forest fragment (Triunfo city, RS, Brazil). Clay
roofing tiles of 24x40 cm served as artificial shelters. The experiment was set in a block design,
with shelter and leaf litter samples. Samplings occurred in the end of each season, with 10
replicates per season (Podgaiski et al., 2007). We captured 731 individuals, 77% being A.
floridana and 23% being B. glaber. ANOVA revealed a significant interaction between treatments
and seasons for A. floridana (P=0.045) and its ovigerous females (P=0.012), but not for B.
glaber (P=0.513). As expected, in summer the abundance of A. floridana under the shelters
increased and decreased in the litter. Abundance of ovigerous females was higher under the
shelters in all seasons with exception of spring. The distribution of isopods was aggregated.
Indexes of species association revealed a negative association of B. glaber with Hymenoptera
and Opiliones (shelters) and with Chilopoda (litter). A. floridana presented a strong negative
association with Opiliones in shelters and a positive association with other detritivorous in both
shelters and litter. We conclude that rocky elements on the soil surface are important shelters for
terrestrial isopods and that their colonization differs markedly between isopod species and
seasons. Life strategies, resistance to desiccation and interaction with invertebrate taxa can
explain the patterns of shelter occupation. Availability of soil microhabitats may influence
community?s fitness and maintenance of the services they provide to ecosystems. MenosBesides the litter layer, natural microhabitats on the soil surface like rocks and coarse wood
