A new arbuscular mycorrhizal fungus was isolated from the Southern Guinea savanna in Benin, which represents a tree-rich savanna in the transi-tion between the tropical atlantic rainforests and grass-rich savannas in sub-Saharan West Africa. The fungus was propagated in bait cultures and monospor...

A new species of the arbuscular mycorrhiza forming Glomeromycetes, Racocetra tropicana,was recently recovered from the semi-humid Atlantic coast line of Northeastern Brazil and from sub-Saharan savannas of Benin (West Africa). It forms yellow to dark yellow glomerospores on (dark) yellow brown sp...

Using ζ-function regularization, we study the one-loop effective action of fundamental strings in AdS5×S5 dual to the latitude 14-BPS Wilson loop in N=4 super-Yang-Mills theory. To avoid certain ambiguities inherent to string theory on curved backgrounds we subtract the effective action of the ho...

We study the one-loop effective action of certain classical type IIA string configurations in AdS4 × ℂℙ3. These configurations are dual to Wilson loops in the N= 6 U(N)k × U(N)−k Chern-Simons theory coupled to matter whose expectation values are known via supersymmetric localization. We compute t...
