Assessment Notes

Taxonomic notes

Paraglomus occultum was formerly called Glomus occultum.

Why suggested for a Global Red List Assessment?

Considering the common record of this species in different ecosystems and countries I suggest its classification as LC.

Geographic range

The species in known in 18 countries. Despite being evidenced for other places, this is the first record of this species on this site for the country.

Population and Trends

There are about 586 records of this species in GBIF. However, so far, this is the first record on the site for Brazil.

Population Trend: Uncertain

Habitat and Ecology

In Brazil, it was found in a preserved area of ​​the Atlantic Forest In Brazil, this species is registered in different biomes, such as Amazon rainforest, Cerrado, Atlantic rainforest, Caatinga and Pantanal and in Southern Cameroon, in savannah under fallow with leguminous plant. However, it can be found in nature almost anywhere.

Subtropical/Tropical Dry ForestDry Savanna


As mandatory symbionts, arbuscular mycorrhizal fungi pass a part of the life cycle associated with a host (plant). Thus, the main threats related to these fungi are the loss of vegetation and soil disturbances

Unintentional effects (species being assessed is not the target)Other ecosystem modificationsHabitat shifting & alteration

Conservation Actions

Soil microorganisms, especially arbuscular mycorrhizal fungi, receive little attention in the field of conservation biology, although they play a crucial role in the production of fundamental ecosystem services, such as fertility, soil formation and maintenance, nutrient cycling and plant community dynamics , among others. For the conservation of these fungi, in addition to the soil, it is also necessary to preserve the associated vegetation.

Resource & habitat protection

Research needed

In a future scenario, it is important to develop an information system that can predict the degree to which plants depend on mycorrhizal fungi and the effects of this association for both symbionts. In this perspective, understanding more about the evolutionary history and ecological aspects of these fungi, can help to understand the variation in functional attributes between species and even predict the result of interactions between the fungus and the host.
