1. The influence of hydraulic conditions on the spatial distribution of macroinvertebrate assemblages was investigated in three riffles in a perennial Australian river. 2. Velocity, depth and variability of substrate roughness were measured at each of 56 macroinvertebrate sampling locations. Complex hydraulic variables (roughness Reynolds number, shear velocity, Froude number) were calculated f...

We tested the hypothesis that different minerals in soil select distinct bacterial communities in their microhabitats. Mica (M), basalt (B) and rock phosphate (RP) were incubated separately in soil planted with Trifolium subterraneum, Lolium rigidum or left unplanted. After 70 days, the mineral and soil fractions were separated by sieving. Automated ribosomal intergenic spacer analysis was used...

BACKGROUND Up to 70% of atopic asthmatics have a positive skin test to the dust mite allergen Der p 1. Reduction of dust mite numbers by lowering room humidity control is one suggested technique for reducing dust mite allergen levels to clinically acceptable levels. Trials of this technique in temperate climates have reported mixed results. It has been speculated that one reason for this is tha...

plexity of soil affects the probability of bacteria encountering appropriate substrates or other bacteria. The Soil bacteria function in the three-dimensional space in heterogequantitative assessment of bacteria in soil is mostly conneous soil complex and their activities depend in part on encountering substrates at the microbial scale. The bacterial density per gram of fined to population dens...

This paper reviews current research on the microbial life that surrounds vertebrate embryos. Several clades are believed to develop inside sterile—or near-sterile—embryonic microhabitats, while others thrive within a veritable zoo of life. The occurrence embryo-associated microbes in some groups, but not others, is an under-appreciated transition (possibly transitions) evolution. A lack compara...

Abstract. Mangrove forests are ecosystems that constitute a large portion of the world's coastline and span tidal zones below, between, above waterline, ecosystem as whole is defined by health these microhabitats. However, we only beginning to understand tidal-zone microbial biodiversity role microbiomes in nutrient cycling. While extensive research has characterized pristine vs. anthropogenica...

In this paper, we provide the first observations of maternal care for the harvestman family Cranaidae. Adult females of two species, Santinezia serratobialis Roewer 1932, which belongs to the group curvipes, and Santinezia sp., which is probably a new species of the group gigantea, were found in association with egg clutches. Since the microhabitats used for oviposition by these species are ver...
