The effects of mixed-species root zones on the resistance of soil bacteria and fungi to long-term experimental and natural reductions in soil moisture

Effect of Nitrogen Addition on Tiger Nut (Cyperus esculentus L.) Rhizosphere Microbial Diversity and Drive Factions of Rhizosphere Soil Multifunctionality in Sandy Farmland

“…These changes signified a shift in fungal growth strategies, conducive to the augmentation of fungal diversity. Simi-larly, PCoA reveals that nitrogen addition significantly influences both bacterial and fungal β diversity (Figure 3a,b), corroborating this hypothesis [9,43]. These findings underscore the importance of nutrient limitation as a key factor shaping microbial community composition [44].…”

“…This disparity may stem from nitrogen fertilization altering the soil's environmental conditions, transitioning the nutrient limitation from a dual carbon-nitrogen constraint to solely carbon, thereby affecting the bacterial community composition. Conversely, fungi, being less impacted by external environmental changes and more by their intrinsic nutritional requirements, demonstrate reduced sensitivity to such environmental alterations [42][43][44]. These changes signified a shift in fungal growth strategies, conducive to the augmentation of fungal diversity.…”

Responses of root-associated fungal communities of mature beech and spruce during five years of experimental drought

“…Likewise, Tedersoo et al (2016) found that soil microbial diversity may depend rather on the general soil context than on tree species numbers. Supporting this, soil microbial communities in mixtures of beech and spruce were found to be hybrids of the respective pure stands (Wilhelm et al, 2023).…”

Drought resistance and resilience of rhizosphere communities in forest soils from the cellular to ecosystem scale – insights from 13C pulse labeling

“…Solly et al ., 2023) to manipulation experiments in natural forest ecosystems (e.g. Wilhelm et al ., 2023). The magnitude of the effects of drought and rewetting often decrease with increasing scale, most likely related to the fact that more extreme conditions are generally applied in smaller‐scale experiments (Gao et al ., 2020), to cofactors varying in natural settings, and to a higher heterogeneity in natural ecosystems combined with larger pool sizes, impeding the detection of short‐term effects (Schrumpf et al ., 2011).…”

“…The impacts of drought on microbial communities range from immediate reductions in metabolic activities, to acclimation of physiological processes, to shifts in species composition under reoccurring drought (Hagedorn et al ., 2016; Hartmann et al ., 2017; Schimel, 2018). In general, fungi have been observed to be rather resistant to drought compared with bacteria (Yuste et al ., 2011; de Vries et al ., 2018; Sun et al ., 2020; Wilhelm et al ., 2023). However, gram‐positive bacteria with a thick peptidoglycan cell membrane layer can be even more resistant to natural drought than fungi (Fuchslueger et al ., 2016; Hartmann et al ., 2017).…”
