Resource islands predict the distribution of heterotrophic bacteria in Chihuahuan desert soils
Article Abstract:
Studies on desert soils show that more microbes are present in the soil containing a large amount of nutrients. In the soil with less nutrients, less microbes are present and these microbes are concentrated around the plants. The distribution of microbes is not affected by any rhizosphere effects because the samples tested did not contain roots as long as those of most of the plants. The results of this study show that the resource island hypothesis correctly states the presence and distribution of microbes in desert soils.

Formation of 30- to 40-micrometer-thick laminations by high-speed marine bacteria in microbial mats
Article Abstract:
Motile heterotrophic marine bacteria form chemotactic microlaminations by increasing their turning frequency in response to oxygen or sulfide gradients. The increase in speed and turning frequency around the microlamination helps in the retention of the microlamination integrity. The mechanism of microlamination formation is contrary to the proposed chemotactic movement mechanism where positive chemotaxis requires a decrease in turning frequency.

Habits of magnetosome crystals in coccoid magnetotactic bacteria
Article Abstract:
The crystal habits of magnetosomes in two coccoid morphotypes of magnetotactic bacteria are studied by using the application of electron holography and high-resolution transmission electron microscopy. It is confirmed that the crystallographic positioning of successive crystals in the magnetsome chain appear to be under strict biological control.
