“…Several studies (Nicolai 1988;Zou 1993;Tian et al 2000) suggested that the chemical composition of plants, including N, lignin content and phenol compounds, plays a crucial role in the properties of soil and litter fauna through their effect on decomposability. The results of this study indicated that the abundance and biomass of earthworms were higher and lower in P. d. 63/51 and P. caspica, respectively.…”

ABSTRACT:We evaluated earthworm abundance and biomass in plantations of different poplar species and clones as well as the effect of some soil chemical and physical properties on them. (P. caspica), as endemic and endangered poplar species, were selected in this study. Earthworm abundance and biomass, soil texture, bulk and particle density (BD, PD), pH, organic carbon (OC), total nitrogen (N), available phosphorus (P) and exchangeable potassium (K) were evaluated. The results showed that the earthworm abundance and biomass, OC, P and N in P. d. 63/51 were higher than in the other poplar species and clones. The correlation coefficients showed a positive correlation of OC, N and a negative correlation of pH, clay, BD and P with earthworm biomass. Based on the results, compared to the other species and clones P. d. 63/51 creates favourable conditions to produce more organic matter and higher abundance and biomass of earthworms, hence it could be beneficial for maintaining the soil quality status for successive plantings.

“…In the terrestrial environment, high temperature and humidity are fundamental for rapid decomposition, since these regulate the metabolism of the decomposing organisms; these conditions can also cause differential liberation of phenolic compounds and the leaching of leaves during decomposition (Nicolai, 1988). According to Souza-Silva et al (2011), unfavorable environmental conditions such as low humidity and low soil temperature may inhibit colonization by animals and decrease the rate of plantdebris processing in terrestrial environments in caves.…”

The litter produced in the exokarst and imported into a quartzite cave were measured, as well as the latter's availability and consumption in aquatic and terrestrial cave habitats. In the exokarst, the litter production increases during the rainy season, although the actual importation of this coarse particulate organic matter into the cave is mainly due to the wind. The sandstone soil and the percolation of water through the epikarst have a filtering effect, and the CPOM input into deeper zones in the cave is limited, despite the presence of a stream. In the terrestrial environment of the cave, percolating water increases plant detritus consumption somewhat during the rainy season, although it is still low, due to the generally dry soil conditions in the cave. The cave can be characterized as an oligotrophic system, especially in the deeper zones, with most invertebrate species occurring near the cave entrances, where the CPOM is more abundant. The forest promotes the presence of trogloxene taxa (opiliones: Goniossoma sp. and Araneae: Enoploctenus sp). Guano in the deeper zones of the cave is extremely scarce and old, so its importance as a basic resource for the cave fauna is quite limited. Conversely, termite colonies and scarce roots recruit trophic resources for the troglophile and troglobite species in the deeper zones. Several cave species were observed in these areas, apparently feeding on roots and the debris left by termites.

“…Those variables are essential to regulate the metabolism of decomposer organisms, besides being able to act differentially in the liberation of phenolic compounds and lixiviation elements during decomposition (Goley 1978, Wieder and lang 1982, nicolai 1988, Humphreys 1991.…”

The temporal budgets of the input, retainment and use by invertebrates of detritus and root tufts were evaluated in a short tropical limestone cave (337 m long). Detritus penetrate only through the stream in lower quantities in the dry season, contrary to what happens in the rainy season. However, water transport energies in the rainy season prevent detritus retainment. Roots tufts that emerge from the bottom of the stream provide shelter and food for several species. The abundance (log 10 ) (R 2 = 0.63; P < 0.02) and richness (log 10 ) (R 2 = 0.63; P < 0.01) related positively with the root tuft biomass (log 10 ). in the terrestrial environment (ground), guano is the main secondary resource available for the invertebrates; the constant production of this resource has shown to influence the structure and distribution of invertebrates. unfavorable temperature conditions and, especially low soil moisture, promote low plant detritus consumption rates. Historically, different authors assumed that organic resources imported by water are more available in caves in rainy seasons. it is clear that the importation of organic detritus in the rainy season is higher than in the dry season, but as shown in this work, the stochastic pulse flows continually disturb and remove the previously accumulated resource. So, the food that is truly used by the cave communities is that transported at the end of the rainy season (and during all the dry season) that becomes available for the cave fauna. The cave functionality depends, so, directly of the epigean food resources.
