Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

Biotropica, Volume 58, Issue 2, March 2026.
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

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...
