TL;DR: The meta-analysis supported the hypothesis that tree growth rate responses to fertilization are weaker in old growth forests and stronger in secondary forests, and found no support for the long-standing hypothesis that plant responses are stronger for P addition and weaker for N addition.

TL;DR: Assessment of the influence of long-term inorganic and organic nutrient additions and nutrient depletion on arbuscular mycorrhizal fungi in a lowland tropical forest in Panama indicates that AM fungal communities are fine-tuned to nutrient regimes, and supports future studies aiming to link AMfungal community dynamics with ecosystem function.

TL;DR: It is hypothesised that reductions in organic matter brought about by litter removal may lead to AM fungi obtaining nutrients from recalcitrant organic or mineral sources in the soil, besides increasing fungal competition for progressively limited resources.

TL;DR: In this article, the authors measured soil carbon and nutrient concentrations at nine depths to 2m after 6 years of continuous litter removal and litter addition in a semi-evergreen rain forest in Panama.

TL;DR: In a lowland tropical forest in Panama, the first systematic investigation into the influence of abiotic factors on the abundance and distribution of mycoheterotrophs is conducted, to ask whether the availability of nitrogen and phosphorus altered the occurrence of my coheterOTrophs and their AM fungal partners.
