“…Up to date, the arbuscular mycorrhizal fungal (AMF) community in the EXO soils has been poorly described when compared to other sites, such as mining areas, desertic areas, and undisturbed habitats (Silva et al 2005;Souza et al 2003;Panwar and Tarafdar 2006;Mergulhão et al 2007;Silva et al 2014;Souza et al 2016a). To our knowledge, this is the first study assessing the soil AMF composition and diversity of EXO soils in the Brazilian tropical seasonal dry forest compared to their respective NAT soils by using morphological characterization.…”

“…First, P. juliflora usually form large monospecific plant populations, as was the case in our study, thus reducing the diversity of host-plants available to the AMF community. Consequently, this changes soil organic carbon inputs (Andrade et al 2009;Dandan and Zhiwei 2007;Oehl et al 2010;Jansa et al 2014;Silva et al 2014;Carneiro et al 2015;Sousa et al 2011;Souza et al 2016a) and decreases AMF's growth and proliferation in the absence of a diverse mycorrhizal plant community (Zubek et al 2013). Secondary metabolites produced by P. juliflora negatively affect native plants growth by disrupting their mutualistic associations with the unaltered AMF community (Andrade et al 2009;Zubek et al 2013).…”

“…This governmental program was proposed to help the regional farmers during dry period providing them with a "tree of life" that would be used as an alternative to fodder and shelter for livestock. But, in fact, this "tree of life" became the most common troublesome invasive exotic plant species in the Brazilian tropical seasonal dry forests affecting native plant community composition and ecological processes in the invaded areas since 1942 (Alves et al 2009;Andrade et al 2009;Souza et al 2016a). …”

Introduction: Here, we compare the arbuscular mycorrhizal fungal (AMF) community composition in soils from the root zone of the exotic invasive species Prosopis juliflora (EXO soils) and soils from the root zone of the native species Mimosa tenuiflora (NAT soils) from five locations in the Brazilian tropical seasonal dry forest, Paraíba, Brazil, using morphological analyses. Results: AMF community composition in EXO and NAT soils were dissimilar. Available phosphorus, diversity index, spore abundance, and species richness were the main factors differing between the EXO and NAT soils. In general, the most dominant order present in the soils were Glomerales (44.8%) and Gigasporales (41.4%). The most abundant AMF genus in all studied soils was Funneliformis. Conclusions: Differences in AMF community composition were associated with (1) differences in the dominant plant species (P. juliflora vs. M. tenuiflora) and (2) changes in soil chemical factors (soil, pH, total organic carbon, total nitrogen, and available P) in EXO soils. These results contribute to a deeper view of the AMF communities in exotic soils and open new perspectives for ecological processes involving AMF species and exotic plant species in the Brazilian tropical seasonal dry forest.

“…Esta fitoinvasora promove alterações na abundância e diversidade da comunidade de fungos micorrízicos arbusculares, assim como em propriedades do solo, como, por exemplo, o pH, alterando as características do solo em questão e promovendo o crescimento desta planta em detrimento das espécies nativas (Souza et al, 2016;Souza et al, 2017). Calotropis procera por sua vez é uma espécie que compete vigorosamente com espécies naturais da Caatinga, sendo assim uma ameaça relevante à biodiversidade do bioma (Leão et al, 2011).…”

A salinização dos solos e um problema que ocorre quando existe um excesso de sais na solução do solo, afetando a pecuária e a agricultura, causando prejuízos econômicos e ambientais. O trabalho objetivou avaliar comunidades vegetais presentes em áreas salinizadas do perímetro irrigado Curu-Recuperação, em Pentecoste-CE. Foram realizadas cinco coletas em duas áreas do perímetro, em três épocas do ano (início da quadra chuvosa, final da quadra chuvosa e estação seca) constituídas de contagem de plantas e coletas de solo. Registrou-se a presença de 37 espécies divididas em 14 famílias, sendo Fabaceae a mais representativa. As espécies Blutaparon vermiculare L., Cyperus rotundus L. e Malachra fasciata Jacq., foram as mais representativas, sendo a primeira espécie com a maior uniformidade na distribuição dentre todas as coletas. O índice de Shannon obtido foi semelhante ao encontrado em áreas sob o efeito do estresse salino. Deste modo, foi possível identificar espécies tolerantes a salinidade no solo e com aplicações alimentícias, medicinais, para uso em programas de haloforraginocultura e na recuperação de solos degradados.Palavras-chave: Halófita, salinidade, semiárido.

The objective of this work was to evaluate plant communities present in salinized areas of the irrigated perimeter Curu-Recuperação, in Pentecoste-CE. Five collections were carried out in two perimeter areas, in three seasons of the year (beginning of the rainy season, end of the rainy season and dry season), consisting of plant counts and soil collections. The presence of 37 species divided into 14 families was recorded, with Fabaceae being the most representative. The species Blutaparon vermiculare L., Cyperus rotundus L. and Malachra fasciata Jacq., were the most representative, being the first species with the greatest uniformity in the distribution in all collections. The Shannon index obtained was similar to that found in areas under the effect of saline stress. Therefore, it was possible to identify species tolerant to salinity in the soil and with food and medicinal applications, for use in haloforraginculture programs and in the recovery of degraded soils.Keywords: Halophytes, salinity, semiarid.

The tripartite associations of arbuscular mycorrhizal fungi (AMF), rhizobia and legumes play a vital role in preserving and even restoring fertility of poor and eroded soils. The present study attempted to quantify relationship between legumes and symbiotic microorganisms (rhizobia and mycorrhizal fungi) by describing the mycorrhizal status and the occurrence of nodualtion of legumes growing in different areas of Jazan. The effect of legume species on soil microbial biomass was also investigated. Mycorrhizal and nodulation intensity varied greatly between legume species. The higher number of nodules (14 nodules per plant) and mycorrhization intensity (54%) were registered in root of Argyrolobium arabicum. Rhizosphere soils of all legume species harbored higher AMF fungal spores than bulk soils. Our results suggest also a significant effect of legumes species on soil microbial biomass. Thus, legume species investigated in this study are potentially useful for replanting and soil protection of most degraded regions of Saudi Arabia.
