Island biogeography of soil bacteria and fungi: similar patterns, but different mechanisms

Isolation and characterization of bacteria and fungi in ambient air of Qeshm Island

Introduction: Many studies have shown an association between respiratory distress, allergic reactions and the presence of bacteria and fungi in air. We aimed to compare the air micro flora of Qeshm Island with those of other provinces. Methods: This experimental study was consisted of grown colonies on PDA, SC media for fungi and BHI, TSA media for bacteria. Samples were taken by Air Trapping...

Island Biogeography: Patterns in Species Richness

Copper resistance mechanisms in bacteria and fungi.

Copper is both an essential micronutrient and a toxic heavy metal for most living cells. The presence of high concentrations of cupric ions in the environment promotes the selection of microorganisms possessing genetic determinants for copper resistance. Several examples of chromosomal and plasmid copper-resistance systems in bacteria have been reported, and the mechanisms of resistance have st...

Island Biogeography Theory: Emerging Patterns and Human Effects

Islands are conventionally (and narrowly) referred to as isolated lands in surrounding waters. However, in broad senses and when loosely defined, ‘islands’ also include insular areas or entities such as mountain tops, lakes (e.g., potholes in northern Great Plains in North America), oasis (in deserts), and springs (especially in deserts) that support unique species assemblages relative to surro...

Cultivation Effect of Chitinase-Transgenic Cotton on Functional Bacteria and Fungi in Rhizosphere and Bulk Soil

Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...
