Arbuscular mycorrhizas in phosphate-polluted soil: interrelations between root colonization and nitrogen [PDF]

open access: yes, 2011
To investigate whether arbuscular mycorrhizal fungi (AMF) – abundant in a phosphate-polluted but nitrogen-poor field site – improve plant N nutrition, we carried out a two-factorial experiment, including N fertilization and fungicide treatment ...

Preliminary Isozyme Evidence on the Hybrid Origin and Diploid Progenitors of Bromus pectinatus (Poaceae) [PDF]

open access: yes, 2007
Isozyme electrophoresis was used to study the origin of Bromus pectinatus (Poaceae, Pooideae). The morphological characteristics of B. pectinatus are intermediate between B. japonicus of sect. Bromus and B. tectorum of sect. Genea.

Oxidative stress in bromus seedlings treated with Salvia sclarea L. aqueous extract

open access: yesBiologica Nyssana, 2016
Extensive use of synthetic pesticides has negative effects on the environment and on human and animal health. Knowledge on allelopathic interactions could provide effective tools for a better exploitation of natural resources in the management of weeds

Interactions of arbuscular mycorrhizal fungi, critical loads of nitrogen deposition, and shifts from native to invasive species in a southern California shrubland [PDF]

open access: yes, 2016
Anthropogenic nitrogen (N) deposition and invasive species are causing declines in global biodiversity, and both factors impact the diversity and functioning of arbuscular mycorrhizal (AM) fungi.

Shrubs indirectly increase desert seedbanks through facilitation of the plant community [PDF]

open access: yes, 2019
The mechanisms supporting positive ecological interactions are important. Foundation species can structure desert biodiversity by facilitating seedbanks of annual plants, but the direct and indirect mechanisms of shrub effects on seedbank have not been ...
