Seasonal Variation of Hypolithic Microbiomes in the Gobi Desert : Seasonal Variation of Hypolithic Microbiomes in the Gobi Desert
Microb Ecol. 2022 May 18. doi: 10.1007/s00248-022-02043-3. Online ahead of print.ABSTRACTUnderstanding how microbial communities adapt to environmental stresses is critical for interpreting ecological patterns and microbial diversity. In the case of the Gobi Desert, little is known on the environmental factors that explain hypolithic colonization under quartz stones. By analyzing nine hypolithic communities across an arid gradient and the effects of the season of the year in the Hexi Corridor of this desert, we found a significant decrease in hypolithic colonization rates (from 47.24 to 15.73%) with the increasing drought ...

Microbial Response to Coastal-Offshore Gradients in Taiwan Straits: Community Metabolism and Total Prokaryotic Abundance as Potential Proxies
This study aimed at assessing microbial distribution and function and their modulation in response to environmental gradients. Surface (0.5 m) water samples from 16 stations along five north to south transects were collected; total prokaryotic abundance by epifluorescence microscope and carbon substrate utilization patterns by Biolog Ecoplates were estimated. Spatially, a patchy microbial distribution was found, with the highest microbial metabolic levels and prokaryotic abundance in the TWS area between Minjiang River estuary and Pingtan Island, and progressive decreases towards offshore stations. Complex carbon sources a...

Responses of Phytoplankton Benthic Propagules to Macronutrient Enrichment and Varying Light Intensities: Elucidation from Monsoon-Influenced Mandovi and Zuari Riverine System : Responses of Phytoplankton Benthic Propagules to Macronutrient Enrichment and Varying Light Intensities: Elucidation from Monsoon-Influenced Mandovi and Zuari Riverine System
Microb Ecol. 2022 May 16. doi: 10.1007/s00248-022-02021-9. Online ahead of print.ABSTRACTThe ecological importance of phytoplankton-benthic-propagules (PBP) from coastal sediments, except tropical monsoon-influenced rivers and estuaries, is well documented. PBP in such systems is often transported from upstream (near freshwater) to downstream (estuary) through freshwater discharges during monsoon and thereby experiences higher salinities (>30 PSU) and nutrients with varying light conditions due to reducing discharges during the monsoon-break/withdrawal-phase. However, the PBP responses (germination and subsequent growth...

Single Cell Analysis Reveals a New Microsporidia-Host Association in a Freshwater Lake
In this study, single cell analysis and fluorescence microscopy were used to detect new host-parasite association within rotifer communities in lake Aydat (France). Our analysis showed the existence of a potential new species belonging to the Crispospora genus able of infecting the rotifer Kellicottia with a high prevalence (42.5%) suggesting that Microsporidia could have a great impact on the rotifer populations' regulation in lakes.PMID:35552794 | DOI:10.1007/s00248-022-02023-7 (Source: Microbial Ecology)

Plant Seeds Commonly Host Bacillus spp., Potential Antagonists of Phytopathogens
Microb Ecol. 2022 May 12. doi: 10.1007/s00248-022-02024-6. Online ahead of print.ABSTRACTIn agriculture, horticulture and plantation forestry, Bacillus species are the most commonly applied antagonists and biopesticides, targeting plant pathogens and insect pests, respectively. Bacillus isolates are also used as bacterial plant biostimulants, or BPBs. Such useful isolates of Bacillus are typically sourced from soil. Here, we show that Bacillus - and other antagonistic microbes - can be sourced from a broad range of plant seeds. We found that culturable Bacillus isolates are common in the seeds of 98 plant species represent...

Experimental Evidence for Manure-Borne Bacteria Invasion in Soil During a Coalescent Event: Influence of the Antibiotic Sulfamethazine
Microb Ecol. 2022 May 12. doi: 10.1007/s00248-022-02020-w. Online ahead of print.ABSTRACTThe fertilization of agricultural soil by organic amendment that may contain antibiotics, like manure, can transfer bacterial pathogens and antibiotic-resistant bacteria to soil communities. However, the invasion by manure-borne bacteria in amended soil remains poorly understood. We hypothesized that this kind of process is both influenced by the soil properties (and those of its microbial communities) and by the presence of contaminants such as antibiotics used in veterinary care. To test that, we performed a microcosm experiment in w...

Gut Site and Gut Morphology Predict Microbiome Structure and Function in Ecologically Diverse Lemurs
Microb Ecol. 2022 May 14. doi: 10.1007/s00248-022-02034-4. Online ahead of print.ABSTRACTMost studies of wildlife gut microbiotas understandably rely on feces to approximate consortia along the gastrointestinal tract. We therefore compared microbiome structure and predicted metagenomic function in stomach, small intestinal, cecal, and colonic samples from 52 lemurs harvested during routine necropsies. The lemurs represent seven genera (Cheirogaleus, Daubentonia, Varecia, Hapalemur, Eulemur, Lemur, Propithecus) characterized by diverse feeding ecologies and gut morphologies. In particular, the hosts variably depend on fibro...
