The environmental niche concept describes the distribution of a taxon in environment and can be used to understand community dynamics, biological invasions, impact changes. uses applications are still restricted microbial ecology, largely due complexity systems associated methodological limitations. development shotgun metagenomics metatranscriptomics opens new ways investigate by focusing on metabolic within space. Here, we propose framework, which, defining fundamental realised microorganisms, has potential not only provide novel insights into habitat preferences metabolism associated, but also inform plasticity, shifts, invasions.

Ecosystem type drives soil eukaryotic diversity and composition in Europe

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(19), P. 5706 - 5719

Published: July 14, 2023

Soil eukaryotes play a crucial role in maintaining ecosystem functions and services, yet the factors driving their diversity distribution remain poorly understood. While many studies focus on some eukaryotic groups (mostly fungi), they are limited spatial scale. Here, we analyzed an unprecedented amount of observational data soil eukaryomes at continental scale (787 sites across Europe) to gain further insights into impact wide range environmental conditions (climatic edaphic) community composition structure. We found that fungi, protists, rotifers, tardigrades, nematodes, arthropods, annelids was predominantly shaped by type (annual permanent croplands, managed unmanaged grasslands, coniferous broadleaved woodlands), higher observed croplands than less intensively systems, such as woodlands. Also more specialized eukaryotes, while between homogeneous compared other ecosystems. The high proportion overlapping taxa ecosystems also indicates DNA has accumulated from previous land uses, hence mimicking transformations occurring Europe last decades. This strong ecosystem-type influence linked properties, particularly, pH richness annelids, plant-available phosphorus drove nematodes. Furthermore, organic carbon total nitrogen ratio crucially explained possibly decades agricultural inputs. Our results highlighted importance long-term variables rather measured time sampling shaping communities, which reinforces need include those addition future monitoring programs conservation efforts.

Initial Observation of Protist from Soil

Springer protocols handbooks/Springer protocols, Journal Year: 2024, Volume and Issue: unknown, P. 7 - 11

Published: Jan. 1, 2024

Soil is a complex and dynamic ecosystem that home to large number of microbial communities. These communities are composed diverse groups organisms, including bacteria, fungi, archaea, protists. Among these, protists the least studied recognized organisms in soil ecosystem, yet they play significant role maintaining health functioning. Despite their ecological importance, often understudied, relatively little known about diversity, distribution, functions. Recent advances molecular techniques have helped shed light on diversity processes, further research this area may important implications for maintenance biodiversity. However, initial observation can give basic idea abundance present soil. Investigating an essential step toward understanding managing ecosystems, it provides insights into interactions between microorganisms nutrients. Therefore, aim chapter provide overview Generally, two different methods used observe naked amoeba active forms ciliates flagellates.

Differential impacts of water diversion and environmental factors on bacterial, archaeal, and fungal communities in the eastern route of the South-to-North water diversion project

Environment International, Journal Year: 2025, Volume and Issue: 195, P. 109280 - 109280

Published: Jan. 1, 2025

Water diversion projects effectively mitigate the uneven distribution of water resources but can also influence aquatic biodiversity and ecosystem functions. Despite their importance, impacts such on multi-domain microbial community dynamics underlying mechanisms remain poorly understood. Utilizing high-throughput sequencing, we investigated bacterial, archaeal, fungal along eastern route South-to-North project during both non-water period (NWDP) (WDP). Our findings revealed competitive exclusion effects among bacterial archaeal communities WDP, characterized by decreased species richness increased biomass, while biomass significantly declined. Distance-decay relationships suggested homogenization WDP. Robustness analyses reduced stability with primarily influencing stability, environmental factors had a greater impact communities. Stochastic processes, homogenizing dispersal drift, intensified for Notably, only functional diversity relative abundance chemoheterotrophic organic compound catabolic bacteria declined photoautotrophic bacteria. PLS-PM indicated that shaped assembly processes guilds, whereas This study enhances our understanding WDP underscores importance assessing direct resulting fluctuations.

Linking biogenic high-temperature ice nucleating particles in Arctic soils and streams to their microbial producers

Aerosol Research, Journal Year: 2025, Volume and Issue: 3(1), P. 81 - 100

Abstract. Aerosols, including biological aerosols, exert a significant influence on cloud formation, influencing the global climate through their effects radiative balance and precipitation. The Arctic region features persistent mixed-phase clouds, which are impacted by ice nucleating particles (INPs) that modulate phase transitions within affecting lifetime impacting region's climate. An increasing number of studies document soils harbor numerous biogenic INPs (bioINPs), but these have yet to be linked microbial producers. In addition, transfer bioINPs from into freshwater marine systems has not been quantified. This study aimed address open questions analyzing soil samples northeast Greenland determine composition along with INP concentrations size distributions.

Abstract The incredibly complex soil microbial communities at small scales make their analysis and identification of reasons for the observed structures challenging. Microbial community structure is mainly a result inoculum (dispersal), selective advantages those organisms under habitat‐based environmental attributes, ability colonizers to sustain themselves over time. Since protective, its inhabitants have long adapted varied conditions, significant portions are likely stable. Hence, substantial portion will not correlate often measured attributes. We suggest that drivers be ranked on basis importance fundamental needs microbes: (i) supply energy, i.e., organic carbon electron acceptors; (ii) effectors or stressors, pH, salt, drought, toxic chemicals; (iii) macro‐organism associations, plants seasonality, animals fecal matter, fauna; (iv) nutrients, in order, N, P, probably lesser importance, other micronutrients, metals. relevance also varies with spatial time scales, example, aggregate field regional, persistent dynamic populations transcripts, extent phylogenetic difference, hence phenotypic differences organismal groups. present summary matrix provide guidance which important particular studies, special emphasis wide range temporal illustrate this genomic population (rRNA gene) data from selected studies.
