“…This is the case of Acacia mearnsii, an Acacia from Australia introduced worldwide to rehabilitate degraded lands, which finally proved highly invasive (Richardson and Rejmanek, 2011). In an invaded Algerian reserve, this Acacia species significantly altered the diversity of the ectomycorrhizal fungal community associated with native Quercus suber trees (Boudiaf et al, 2013). In our study, despite the toxicity of J. curcas tissues and possibly of its rhizodeposits, mycorrhization intensity was stimulated in most cases, and mycorrhization frequency levels were high.…”

“…The number of carbon substrates used by soil microorganisms (S), average well color development (AWCD), Shannon's richness index (H), Simpson's dominance index (D), and relative use efficiency of carbon resources (RUE) were evaluated and used as indicators to assess the soil microbial functional diversity and activity Boudiaf et al 2013). The average well color development reflecting the total ability of microorganisms to use carbon resource was determined using the method reported by Classen et al (2003):…”

“…The change of plant community in composition and structure often leads to the changes of soil microbial community in diversity and function. These changes would have certain impact on the ecological process of soil system that caused the change of plant community in turn (Mummey and Rillig 2006;Patrick 2006;Boudiaf et al 2013). An introduction of forest species often changes obviously the composition, structure, species diversity, and productivity of plant community (Davies 2011;Omoro et al 2010;Powell et al 2013).…”

Effects of exotic species Larix kaempferi on diversity and activity of soil microorganisms in Dalaoling National Forest Park

Introduction: Soil microbial community plays a crucial role in the ecological processes of soil ecosystem. Forest species introduction often changes profoundly soil ecological processes in the forest. Larix kaempferi (Lam.) was introduced to China from Japan as a timber tree species in the 1960s. The activity and functional diversity of soil microorganisms in the L. kaempferi forest in Dalaoling National Forest Park in Hubei Province, China, was studied to evaluate the effects of this exotic species on the local soil ecosystems. Methods: Quadrates were set up randomly in the L. kaempferi forests cultivated in 1990 and 1996 and the surrounding Pinus armandii forest cultivated in 1990. Soil samples were collected using a soil corer at five locations along the diagonals in each quadrat. The activity and functional diversity of soil microorganisms were tested using the BIOLOG technique in laboratory. Results: The diversity, activity, and carbon utilization pattern of soil microorganism community and soil physicochemical properties were all impacted by the introduced species. The average well color development (AWCD) and Shannon's richness index (H) of the soil microorganism community in the L. kaempferi forest decreased with the increase in forest age and were significantly lower than those in the surrounding native P. armandii forest. The carbon source utilization pattern of soil microorganism community in a 23-year-old L. kaempferi forest differed significantly from a 17-year-old L. kaempferi forest and the P. armandii forest. The introduced species also resulted in the changes of soil physicochemical properties. The organic material content, total nitrogen, available nitrogen, and total phosphorus in the soil of L. kaempferi forest were significantly lower than those in the soil of P. armandii forest. Conclusions: Introduction and long-time cultivation of L. kaempferi significantly altered the soil microbial functional diversity and activity and the soil physicochemical properties. The alteration increased with the increase of forest age.

The aim of this study was to test the impact of Rhizophagus irregularis, an arbuscular mycorrhizal fungus (AMF), on durum wheat growth and soil microbial functionalities in a field inoculation trial conducted in Morocco. The results showed that i) the R. irregularis inoculum effectively improved wheat growth, ii) wheat growth promotion depended on the soil mycorrhizal infectivity and iii) functional abilities of soil microflora depended on AMF inoculation. This study confirms that field AMF inoculation can be proposed as an effective agronomic practice in wheat production and as a sustainable cultural practice to manage soil biofunctioning. To fully promote inoculation practices, a better knowledge of AMF ecology has to be acquired to better adapt AMF inoculation to environmental conditions, and thus warrant better yields and agricultural sustainability.
