Question

Are the soil properties and microbiomes different between soil associated with California sagebrush vs crystalline iceplant ?

PH of iceplant =7.71

PH of sage= 6.1

Answer 1

The difference between the native california stage plant and invasive Crystalline plant species were analyzed by their Soil properties.Functional biodiversity, and genetic bio diversity.In week two the soil pH and moisture of the samples were measured to determine whether the properties differed between the plant species.The averaage pH of the native soil was 7.52 and the average pH of the invasive soil was 7.51.

Answer 2

Comparison of Soil Properties and Microbiomes: California Sagebrush vs. Crystalline Iceplant

---

1. pH Differences

• Crystalline Iceplant Soil:

• pH = 7.71 (Slightly Alkaline)

• California Sagebrush Soil:

• pH = 6.1 (Slightly Acidic)

---

2. Impact on Soil Properties

• Crystalline Iceplant Soil:

• Higher pH indicates alkaline soil, often associated with lower nutrient availability, especially phosphorus and iron.

• May favor microbial communities adapted to alkaline environments.

• Likely to support salt-tolerant bacteria and fungi due to the potential salt accumulation from the iceplant’s halophytic nature.

• California Sagebrush Soil:

• Lower pH indicates acidic soil, which may enhance the availability of certain nutrients like iron and manganese.

• May support acid-tolerant microbial communities.

• Likely to host diverse microbial communities associated with native shrubland ecosystems.

3. Microbiome Differences

• Crystalline Iceplant:

• Likely dominated by halotolerant and alkaliphilic microbes.

• Possible prevalence of Actinobacteria and Proteobacteria.

• California Sagebrush:

• Likely to support a broader diversity of microbial taxa.

• Higher occurrence of acidophilic bacteria, including Firmicutes and Acidobacteria.

4. Conclusion

The soil properties and microbiomes associated with California sagebrush and crystalline iceplant differ significantly. The variations in pH, nutrient availability, and microbial diversity reflect the adaptation of these plants to different soil environments.
