Tropical Andean Forests Are Highly Susceptible to Nutrient Inputs—Rapid Effects of Experimental N and P Addition to an Ecuadorian Montane Forest
It is shown that Neotropical montane rainforests respond rapidly to moderate additions of N and P, which suggest marked changes in species composition and diversity of these forests by nutrient inputs in the long term.
Litter mixture effects on decomposition in tropical montane rainforests vary strongly with time and turn negative at later stages of decay

The results suggest that the decomposer system of tropical montane rainforests significantly responds to even moderate changes in nutrient inputs with the potential to cause major ramifications of the whole ecosystem including litter decomposition and plant growth.

The high energy flux into large decomposers but low energy fluxes to other trophic guilds suggests that trophIC multifunctionality of belowground communities is compromised in plantation systems.

The results show that, irrespective of litter origin and type, unfavorable microenvironmental conditions at high altitudes inhibit decomposition processes resulting in the sequestration of carbon in thick organic layers.
New taxa and new records of oribatid mites of the family Galumnidae (Acari: Oribatida) from Ecuador.
The new genus Neoctenogalumna gen. nov. with Ctenogalumna moresonensis Engelbrecht, 1972 as a type species and the new subgenus Neoctenogalumna (Paractenogalumna) subgen. nov. with Neoctenogalumna…
Roots, mycorrhizal fungi and altitude as determinants of litter decomposition and soil animal communities in tropical montane rainforests

The results indicate that in nutrient limited tropical montane rainforests mycorrhizal fungi suppress the activity of other microorganisms, potentially competing for litter-derived resources, at each of the investigated altitudes.
