Assessment Notes

Taxonomic notes

Also known as Rhizogglomus irregulares or Glomus irregularis, their spores generally form as dense clumps within the roots. They have variable color (hyaline to yellow) and 70-165 µm in diameter.


Why suggested for a Global Red List Assessment?

Due to the lack of adequate information to make a direct or indirect assessment of its risk of extinction, based on its distribution and / or population status, I would suggest that this species be categorized as insufficient data (DD).


Geographic range

There are about 39 registrations in 7 countries (GBIF). On this website, this is the first record for Brazil. However, this species, besides Bahia, had been mentioned for Minas Gerais, for example.


Population and Trends

Possibly, changes in the species nomenclature make it difficult to record occurrences on this site. Based on this and in the absence of registration for Brazil, it is believed that the number for this species is even greater.

Population Trend: Improving


Habitat and Ecology

In Brazil, this species is registered in different biomes, such as Cerrado, Atlantic rainforest and Caatinga

Subtropical/Tropical Dry ForestDry Savanna

Threats

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

Housing & urban areasScale Unknown/UnrecordedIntentional use (species being assessed is the target)

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

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.
