Distance decay of tree species similarity in protected areas on terra firme forests in colombian amazonia... The study site comprised three National Natural Parks, Tinigua, Chiribiquete, and Amacayacu, located in different geological units that represent a soil fertility gradient linked to parental materials....
Root traits of new zealand trees: community-level responses to a soil fertility gradient, and plastic responses to nutrient availability... In this thesis I aimed to determine the relationships between seedling fine root, leaf, and stem traits of New Zealand tree species, and investigate whether these traits related to species‟ abundance along a soil fertility gradient....
Nitrogen cycling in agroecosystems: the effects of soil fertility and plant species interactions on legume nitrogen fixation... My research objectives were to investigate: 1) the effects of legumebased management on soil organic matter (SOM) pools; 2) the effects of a SOM-based fertility gradient on BNF; and 3) how plant phenology and species interactions affect BNF across the fertility gradient....
Edaphic selection pressures as drivers of contrasting white spruce ectomycorrhizal fungal community structure and diversity in the canadian boreal forest of abitibi-témiscamingue region.... Ectomycorrhizal (ECM) fungal community structure and diversity was studied at the four locations with soil fertility gradient through morpho-molecular and phylogenetic analyses in relationships with rhizospheric soil chemical properties....
