Seasonal and spatial distribution of roots and arbuscular mycorrhizal fungi under live fences ofAcacia laetaandAcacia melliferain Sénégal

Arbuscular mycorrhizal soil infectivity and spores distribution across plantations of tropical, subtropical and exotic tree species: a case study from the forest reserve of Bandia, Senegal

“…This behaviour corroborates reports of Ingleby et al . () who previously showed a low sporulation in nearby area with essentially similar clay contents to those of the present study site and those of Diagne, Seck & Gassama‐Dia () when they studied AM fungi distribution under live fences of Acacia laeta and Acacia mellifera at Bambey. But greater spore numbers were reported in the same country by Diop et al .…”

“…This observation was also confirmed by results obtained in the plantation of C. integrifolia where there is a poor survival of the tree plants, and this has lead to an open canopy areas and more ground vegetation with concomitant inputs of AM propagules. Our result confirms earlier studies, where difference on spore concentrations between tree species was attributed to differences on the ground vegetation under these trees (Ingleby et al ., ; Diagne, Seck & Gassama‐Dia, ). Together with our data, these findings support the view that increased soil MIP is because of increasing richness and density of highly mycotrophic herbaceous plants beneath the tree species.…”

“…Together with our data, these findings support the view that increased soil MIP is because of increasing richness and density of highly mycotrophic herbaceous plants beneath the tree species. Research carried out in recent decades corroborates such a statement and emphasizes the role of herbaceous species in sustaining soil mycorrhizal inoculums (Duponnois et al ., ; Zhang, Gui & Liu, ; Diagne, Seck & Gassama‐Dia, ; Guadarrama et al ., ).…”

“…This land degradation adversely affects soil physic‐chemical and microbiological characteristics (Duponnois et al ., ; Remigi et al ., ) and thereby leads to the genesis of degraded ecosystems. Such a degraded land needs proper ecological rehabilitation through which soil can be ameliorated to support biological productivity (Ingleby et al ., ; Duponnois et al ., ; Diagne, Seck & Gassama‐Dia, ). Many studies have supported that the presence of the tree species provide a number of ecological advantage through increased soil organic matter content, biodiversity conservation, and improved soil microbial activity and nutrient cycling rates (Mungai et al ., ).…”
