We explore here the occurrence of aggressive ants in an apparently symbiotic relationship with the savanna tree Acacia drepanolobium and their effects on giraffe herbivory on the Athi-Kapiti Plains, Kenya.

Gums from Acacia senegal and seyal improved foamability of different bentonite-treated wines. Our main goal was see how supplementation with new fractions separated gums by Ion Exchange Chromatography affected wines, deepening relati...

The western region of Saudi Arabia is a major vegetation diversity hotspot with wide range habitats and variant climatic topographical characteristics. in this has not been fully studied to monitor the changes that happen over time these habitats. This study aims identify floristic structure plant species invaded Arabia. A total 58 stands different (i.e., mountains, protected areas “ridge mount...
