Four commonly employed biotic indices based on macrofauna composition: BMWP (British Monitoring Working Party score system), ASPT (Average Score Per Taxon), DSFI (Danish Stream Fauna Index) and FBI (Family level Biotic Index) were used to assess environmental quality of six small slow-flowing lowland streams (Masurian Lakeland, North-eastern Poland). Their efficiencies in determining the level of degradation, assessed by the simoultaneous measuring of the main abiotic parameters of water, were tested. The search for relationships between both abundance and percentages of invertebrate taxa and values of the main abiotic parameters with multiple regression analysis resulted in determining an indicative value for certain taxa. Results of discriminant function analysis show, that environmental quality can be predicted accurately on the basis of macrofauna composition in 94–100% of the sites. However, none of tested indices classified the sites to particular classes of degradation with sufficient accuracy. The relationships between the values of all tested indices and the values of Cumulative Index of Environmental Quality (CIEQ) based on abiotic parameters, expressed as coefficients of linear regression, were very low and ranged between 0.006 and 0.068. Therefore, a new regional, macrofauna-based biotic index, APODEMAC, is proposed as a better tool for environmental quality assessment. Values of APODEMAC are strongly dependent on values of CIEQ (R²= 0.641), and their seasonal variance is lower than that of other indices. Coefficient of linear regression between CIEQ values and APODEMAC was 9 to almost 100 times higher than for other tested biotic indices. The selection of indicator taxa used in APODEMAC procedure was based on comparisons between the taxa densities at sampling sites differing in terms of environmental quality and on the results of multiple regression and discriminant analysis. The importance of certain taxa of molluscs, leeches and dipterans in this procedure is much higher, while the importance of mayflies, stoneflies and caddisflies is much lower than in BMWP, ASPT, FBI and DSFI. The occurrence of the various larval insects in the studied environments seems to be limited rather by substrate type than by the chemical quality of stream water. Application of simple regional biotic indices like APODEMAC is suggested as an, in some cases, easier, cheaper and less time-consuming way of biological assessment compared to complicated and time-consuming implementation of the existing indices.

The marine species richness (MSR) recorded in 159 sandy beach surveys was analysed in relation to beach width (W). MSR is the number of macrobenthic species collected in a standard intertidal transect survey, excluding insects. Beach width (W) was estimated by dividing the spring tide range [m] by the beach face slope, to give a value in [m]. The relationship between MSR and W was best described by a semilog (exponential) model, which was highly significant: MSR = −5.2+ 10.8 logW. The fit of a power model (MSR = cWz) was also significant. The steep slope of the curve for a power model (z = 0.49) suggests that beaches function as isolated rather than contiguous habitats and that the nature of the habitat becomes more benign as beaches widen. There are some latitudinal effects, with tropical beaches displaying a higher species-area relationship for any beach width than other regions.

The search for global regularities governing the biodiversity of living organisms has a long history, and altitudinal gradients have explanatory power. To determine whether soil animals exhibit altitudinal gradients of abundance and diversity and to assess the impact of plant communities (meadows and forests) on any observed patterns, we studied soil invertebrates along an altitudinal gradient of 500–1000 m a.s.l. in the Silesian Beskid Mts (Western Carpathians). Ten study plots were established in three vegetation zones in meadows and also forested sites (spruce, beech, oak-hornbeam, riparian). In spring, summer and autumn of 2004, 2005 and 2006, five soil samples (20 × 20 × 25 cm) were dug from every study plot on each occasion and invertebrates were separated from the soil by hand-sorting . Earthworms were identified to species, and other invertebrates to higher taxa. The two types of plant associations studied (meadow, forest) differed significantly in the population density and biomass of soil invertebrates – earthworms were more numerous in meadows (132.3 ind. m⁻² in meadows and 24 ind. m⁻² in forests) and other invertebrates in forests (57.7 ind. m⁻² in meadows and 67.4 ind. m⁻² in forests). Density tended to be higher in summer than in other seasons, and at minimum in autumn. Meadows of foothills and the lower montane zone were richest in earthworm species (7 species). Upper montane meadow, upper montane spruce forest and lower montane beech forest were poorest in earthworms (2 species).The most abundant animals among other invertebrates were larvae of Coleoptera and Diptera. Coleoptera larvae dominated at higher altitudes. The density and biomass of earthworms in meadows correlated negatively with elevation (density, r = -0.52, biomass r = -0.66). The corresponding correlations for other invertebrates were much weaker (density, r=-0.32; biomass, r = -0.31). The diversity of earthworms tended to decrease with altitude in meadows. Sites at higher elevations were poorer in species of both earthworms and other invertebrates. For both earthworms and other invertebrates in spruce forest there were no differences in biodiversity indices along the altitudinal gradient.

Intertidal zone of four gravel beaches in Hornsund Fjord (West Spitsbergen) were investigated in order to study macrofaunal distribution and diversity in these poor habitats. A total of 12 macrofaunal taxa were found in the collected material. The most frequent and the most abundant taxon was Lumbricillus sp. (Oligochaeta). The next most numerous group were juvenile Gammarus spp. juv. The fauna included also polychaetes, molluscs and other crustaceans. The diversity measured with Shannon-Weaver index was low and varied from 0 to 1.4. The analysis revealed that there were no statistically important differences in macrofaunal distribution among stations in fjord. However there were significant differences among various tidal mark zones and high patchiness in animals abundance at each station. Also species composition, density and biomass were diversified along the tide level profile.

The paper contains the results of a study on the dependence of the qualitative and quantitative structure of the phytophilous macrofauna dwelling on Stratiotes aloides L. (water soldier) on the quality of waters in a lentic oxbow lake of the £yna River. The observations were carried out during the vegetative season (April – June) 2006 at high and moderate water levels. During the study, a total of 18 taxa of invertebrates dwelling on the above plant species were identified, with the exact number of taxa varying in time: 11 taxa were noticed in April and May, and in June their number went up to 13. The examination of hydrochemical parameters of the oxbow lake waters revealed that the density of macrofauna was lower at higher values of proper conductivity and macronutrients, ammonia nitrogen and COD, increasing at high levels of sulphates. High concentrations of ammonia nitrogen and non-organic components coincided with decreased biomass of epiphytic animals on water soldier. Additionally, it has been observed that elevated concentrations of potassium ions have a negative influence on the biomass of most epiphytic animals (except Erpobdella sp.).

On nine beaches and two transects in the surf zone along the Dutch coast the presence of benthic macrofauna was studied in relation to basic abiotic characteristics. According to Short’s classification system, Dutch beaches are mesotidal and dissipative (Ω = 8.6), and the RTR is low (1.52–1.27), which means that they are not tide-dominated. BSI ranged from 1.4 to 1.1 for the northern and western Dutch coasts respectively and had an overall value of 1.2. The rates of exposure of the beaches varied between 8 and 12, and are therefore regarded as sheltered to moderately exposed. The Dutch beaches display a geographical trend in beach types. Those of the Wadden Sea islands in the northern part of the Netherlands are dissipative, flat, fine-grained, and host high densities of many species of benthic macrofauna. The beaches along the western Dutch coast are less dissipative, steeper, with a higher mean grain size; the species diversity and abundance there are lower. Species diversity and abundance on the beaches increase from the high- to the low-water line. The maximum number of species was found between 0 and –1 m relative to the mean tidal level. The abundance peaks just above the mean tidal level, while the biomass reaches a maximum at the mean tidal level. Species diversity and abundance are low in the surf zone, but increase towards deeper water. Species numbers are high and the abundance is very high in the trough between the two bars. The relation between the diversity and abundance of macrobenthic species on the one hand, and the sediment composition, water column depth, and position between the bars on the other show a clear pattern of zonation for the beach, surf zone and near-shore: (1) a supralittoral zone with insects and air-breathing crustaceans, (2) a midshore zone, with intertidal species, (3) a lower shore zone, whose species extend into the shallow surf zone, and (4) a zone of sublittoral fauna in the trough between the two breaker bars within the surf zone.

Studies were carried out in 1999 and 2000 in the vicinity of Turew near Poznaƒ (West Poland) and dealt with the composition, density and biomass of soil-litter macrofauna with special reference to dipteran larvae in the agricultural landscape. Sites were located on a 7- years old mid-field shelterbelt and on adjacent field with maize crop in the first and wheat crop in the second year of study and – on 9 various patches of vegetation within the mid-field shelterbelt. Studies carried out along the transect: the shelterbelt (S) – ecotone (E) – field 10 m (F 10)– field 50 m (F 50) demonstrated a decline of: 1) animal density (10 times) and biomass (30 times) of total macrofauna and (80 times) of dipteran larvae, 2) taxonomic richness and biodiversity measured with the H` index, 3) individual weight of the entire macrofauna, of dipteran larvae, saprophagous animals and predators so that the individuals became smaller with the distance from the shelterbelt, 4) similarity of macrofauna communities in terms of composition and dominance structure, with increasing distance between plots. Close relationship was found between plant cover and soil-litter macrofauna. Species composition, density, biomass and trophic structure of soil invertebrate community depended on tree or herb species. Those soil animals and especially dipteran larvae were a sensitive indicator of small-scale habitat changes.

A tendency to an increase in electrolytes and nutrients (mineral nitrogen and total phosphorus) was found. The bottom macrofauna was not affected by human activity in the period from 1955 to 1982, when the degree of eutrophication was small. From 1983 the effect of human activity was revealed in both qualitative and quantitative changes in the composition of the macrofauna.

Numerous original and review papers have emerged over recent years concerning the natural microbiota and its interaction with the mammal host’s body. This addendum supplements in short our previous review article on the role of microbiota in the host immunity [1] paying particular attention to such essential aspects as the composition and role of gut microbiota in viral infections as well as the interplay between the microbiota and the macrofauna inhabiting the mammalian gastrointestinal tract. The host immune system, commensal microbiota and macrofauna are elements of an integrated system in which the relationships are bidirectional. As demonstrated in the article, virus or helminth infection alters the composition of commensal gut microbiota but, in turn, commensal microbiota influences the fate of a virus or helminth infection. Natural microbiota located on external and internal surfaces of the host body is a prominent element of its health and condition, including the functioning of the immune system [1,2,3]. The gastrointestinal tract harbors the highest number and the greatest diversity of microbial organisms, so the studies presented in the article regard gut microbiota.
