The density and diversity of Arbuscular mycorrhizal spores on land covers with different tree canopy densities at the UNS educational forests

Abstract

Mycorrhiza is a ‘super-organism,’ potential to support plants facing increment temperatures due to more open tree canopy cover. This research aimed to study how three different land covers affect the abundance and diversity of mycorrhiza spores in the UNS educational forests. The research was descriptive-explorative with a survey approach on three land covers with different canopy densities, i.e.: (1) mahogany, (2) pine, and (3) pine replanting, with a canopy cover of 95.56%, 80.93%, and 16.50%, respectively. Soil samples were taken by purposive random sampling at several points at a soil depth of 0-30 cm in a 200 m2 transect, then composited. Repeated each land cover was four times. The results showed that land cover with a more open canopy had a higher density of mycorrhiza spores than a dense canopy. The spores’ density on the land cover of Pine replanting> Pine> Mahogany was 865, 761, and 608 spores/100 g of soil, with a diversity index (H’) 1.00; 0.63; and 0.88, respectively. The types of spores found were Gigaspora sp., Glomus sp., and Archaeospora sp. Mycorrhizal spore density was related to soil temperature (r = 0.56*) and C-organic (r = - 0.68**). Mycorrhizae provide new hope to support plant tolerance facing higher temperatures due to climate changes at the UNS educational forests.

Multidimensional analysis reveals environmental factors that affect community dynamics of arbuscular mycorrhizal fungi in poplar roots

“…Although we found the opposite interaction, these findings suggest that the relationship between AMF and soil N content is sensitive; it may be altered by changes in altitude, temperature, precipitation, soil type, and host plant. In the present study, AMF spore density was negatively correlated with SOM, which was similar to the results of previous studies in the Universitas Sebelas Maret educational forest (Dewi et al, 2021) and a Chilean Mediterranean-type ecosystem (Silva-Flores et al, 2019); thus, low SOM is presumably associated with high mycorrhizal spore density. Multiple variables may have some effects on the composition of the AMF community.…”

The Assessment of Soil Quality and Earthworms as Bioindicators in the Alas Bromo Education Forest, Central Java, Indonesia

“…Like other tropical forests, the Alas Bromo Forest provides numerous environmental benefits and indirectly contributes to biodiversity conservation and climate regulation [2]. In addition to being essential as carbon sinks that support stable carbon storage [3], regulating the water system, and providing livelihoods and various forest products [4]. The primary objective of Universitas Sebelas Maret is to protect and preserve the Alas Bromo forest's health.…”

“…The Alas Bromo Forest has numerous land cover types, including pine, mahogany, pine-mahogany, a mixture of trees, open land, and seasonal plants [7]. The tree canopy densities of these land covers vary, influencing the soil's physical, chemical, and biological characteristics [4]. The diversity of vegetation within a land cover can influence soil structure and nutrient leaching [8], [9].…”
