Adaptive Significance of Nickel Hyperaccumulation by Plants
Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...

We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

ABSTRACT In West Africa, trees and shrubs are important for feeding ruminant livestock during the dry season. This study aimed to determine the in vitro digestibility of organic matter from eight woody species using a gas test with and without the addition of polyethylene glycol (PEG), and evaluate their preference by sheep using a cafeteria test ...
