The relationship between plant and soil bacterial community in tundra soil, Alaska

Abstract

High latitude ecosystems are affected by warming faster than other temperate and tropical regions, and actually the climate of the Arctic has warmed significantly recent few decades. Plants have been focused on their responses can affect entire food webs, disturbance regimes, carbon and nutrient cycling, and water supply. Furthermore, soil microorganisms play a key role in nutrient cycling and other ecosystem process. In spite of the plant and soil microorganisms are good source to predict to the climatic changes, their relationships are not understood well. Thus researches are needed to explain the relationship between vegetation and soil bacterial community in Arctic area. Here, we asked the question: 1) which kind of plant is dominant, 2) and the dominant plant affect to the bacterial communities structures?, 3) and which environmental factors affect to the plant and bacterial community structure? To answer these questions, we investigated type of plant using quadrate (30 cm x 30 cm) with 25 m intervals and the soil bacterial community with the sampling sites using 16S rRNA gene sequencing. Also statistical analyses were carried out to identify the relationships between soil properties and plant and bacterial community.t entire food webs, disturbance regimes, carbon and nutrient cycling, and water supply. Furthermore, soil microorganisms play a key role in nutrient cycling and other ecosystem process. In spite of the plant and soil microorganisms are good source to predict to the climatic changes, their relationships are not understood well.
