Abstract: In soil, Acidobacteria constitute on average 20% of all bacteria, are highly erse, and are physiologically active in situ . However, their in idual functions and interactions with higher taxa in soil are still unknown. Here, potential effects of land use, soil properties, plant ersity, and soil nanofauna on acidobacterial community composition were studied by cultivation-independent methods in grassland and forest soils from three different regions in Germany. The analysis of 16S rRNA gene clone libraries representing all studied soils revealed that grassland soils were dominated by subgroup Gp6 and forest soils by subgroup Gp1 Acidobacteria . The analysis of a large number of sites ( n = 57) by 16S rRNA gene fingerprinting methods (terminal restriction fragment length polymorphism [T-RFLP] and denaturing gradient gel electrophoresis [DGGE]) showed that Acidobacteria ersities differed between grassland and forest soils but also among the three different regions. Edaphic properties, such as pH, organic carbon, total nitrogen, C/N ratio, phosphorus, nitrate, ammonium, soil moisture, soil temperature, and soil respiration, had an impact on community composition as assessed by fingerprinting. However, interrelations with environmental parameters among subgroup terminal restriction fragments (T-RFs) differed significantly, e.g., different Gp1 T-RFs correlated positively or negatively with nitrogen content. Novel significant correlations of Acidobacteria subpopulations (i.e., in idual populations within subgroups) with soil nanofauna and vascular plant ersity were revealed only by analysis of clone sequences. Thus, for detecting novel interrelations of environmental parameters with Acidobacteria , in idual populations within subgroups have to be considered.

Abstract: We describe a new species of the genus Hemiphyllodactylus on the basis of four specimens from Cao Bang Province, northern Vietnam. Hemiphyllodactylus zugi sp. nov. is distinguished from the remaining congeners by a combination of the following characters: a bisexual taxon average SVL of adult males 41 mm, of adult female 46.6 mm chin scales bordering mental and first infralabial distinctly enlarged digital lamellae formulae 3-4-4-4 (forefoot) and 4-5-5-5 (hindfoot) femoral and precloacal pore series continuous, 18-21 in total in males, absent in female cloacal spur single in males dorsal trunk pattern of dark brown irregular transverse bands dark lateral head stripe indistinct upper zone of flank with a series of large light spots, edged above and below in dark grey caecum and gonadal ducts unpigmented.

Abstract: As the most abundant animals on earth, nematodes are a dominant component of the soil community. They play critical roles in regulating biogeochemical cycles and vegetation dynamics within and across landscapes and are an indicator of soil biological activity. Here, we present a comprehensive global dataset of soil nematode abundance and functional group composition. This dataset includes 6,825 georeferenced soil s les from all continents and biomes. For geospatial mapping purposes these s les are aggregated into 1,933 unique 1-km pixels, each of which is linked to 73 global environmental covariate data layers. Altogether, this dataset can help to gain insight into the spatial distribution patterns of soil nematode abundance and community composition, and the environmental drivers shaping these patterns.

Abstract: Land-use intensification is a major driver of bio ersity loss. However, understanding how different components of land use drive bio ersity loss requires the investigation of multiple trophic levels across spatial scales. Using data from 150 agricultural grasslands in central Europe, we assess the influence of multiple components of local- and landscape-level land use on more than 4,000 above- and belowground taxa, spanning 20 trophic groups. Plot-level land-use intensity is strongly and negatively associated with aboveground trophic groups, but positively or not associated with belowground trophic groups. Meanwhile, both above- and belowground trophic groups respond to landscape-level land use, but to different drivers: aboveground ersity of grasslands is promoted by erse surrounding land-cover, while belowground ersity is positively related to a high permanent forest cover in the surrounding landscape. These results highlight a role of landscape-level land use in shaping belowground communities, and suggest that revised agroecosystem management strategies are needed to conserve whole-ecosystem bio ersity.
