Benthic eDNA metabarcoding provides accurate assessments of impact from oil extraction, and ecological insights

Ecological Indicators, Год журнала: 2021, Номер 130, С. 108064 - 108064

Apart from its contribution to climate change, offshore oil and gas extraction is also a potential threat the diversity function of marine ecosystems. Routine monitoring environmental status affected areas therefore critical for effective management. While current morphology-based relatively time consuming, costly prone identification bias, DNA metabarcoding offers an attractive alternative assessing impacts drilling, or spills. However, be ready routine monitoring, performance needs demonstrated through agreement with assessments based on physicochemical measurements bioindicators. To this end, we applied sequence metazoan (COI) total eukaryotic (18S) benthic components. We targeted range sites, gradient low high level impact, located near active production installations reference in North Barents Seas. Alpha community structure both datasets correlated strongly pressure index (PI) hydrocarbons (THC), PAH16, Ba Cu. Calculations macroinvertebrate-based Norwegian Sensitivity Index (NSI) COI data agreed well corresponding morpho-taxonomy values PI. Further, identified set bioindicator taxa datasets, develop novel biotic indices demonstrate their predictive using cross-validation. Finally, compared co-occurrence networks impacted vs. non-impacted improve understanding ecological consequences impacts. Our study demonstrates that can act as meaningful accurate complement morpho-taxonomic approach.

Molecular Data Reveal a Cryptic Diversity in the Genus Urotricha (Alveolata, Ciliophora, Prostomatida), a Key Player in Freshwater Lakes, With Remarks on Morphology, Food Preferences, and Distribution

Frontiers in Microbiology, Год журнала: 2022, Номер 12

Species of the ciliate genus Urotricha are key players in freshwater plankton communities. In pelagial lakes, about 20 urotrich species occur throughout an annual cycle, some which play a pivotal role aquatic food webs. For example, during phytoplankton spring bloom, they consume remarkable proportion algal production. ecological studies, ciliates usually merely identified to rank and grouped into size classes. This is unsatisfying considering distinct autecological properties individual their specific spatial temporal distribution patterns. As basis for future research, we characterized detail four common morphotypes, i.e., specimens as U. furcata tentatively agilis, pseudofurcata, castalia, using state-of-the-art methods. We used integrative polyphasic approach, morphological studies (in vivo observation, silver staining methods, scanning electron microscopy) were linked with molecular approach exploiting different gene fragments taxonomic DNA barcodes resolution potential (SSU rDNA, ITS-1, ITS-2, hypervariable V4 V9 regions SSU rDNA). shed light on diversity well global patterns, cycles. Additionally, coupled occurrences environmental parameters, subsequently modeled occurrence, logistic regressions. Furthermore, one strain putatively ascertained optimal cultivation media preferences. Thereby, our comprehensive view these important that frequently high throughput sequencing datasets worldwide will allow better exploit protistan data from lakes.

Long-term dynamics of the human oral microbiome during clinical disease progression

BMC Biology, Год журнала: 2021, Номер 19(1)

Опубликована: Ноя. 6, 2021

Abstract Background Oral microbiome dysbiosis is linked to overt inflammation of tooth-supporting tissues, leading periodontitis, an oral condition that can cause tooth and bone loss. Microbiome has been described as a disruption in the symbiotic microbiota composition’s stability could adversely affect host’s health status. However, precise dynamics lead progression disease are largely unknown. The objective our study was investigate long-term periodontitis its connection dysbiosis. Results We studied three different teeth groups: sites showed progression, remained stable during study, exhibited cyclic deepening followed by spontaneous recovery. Time-series analysis revealed communities characteristic succession bacteria clusters. Stable fluctuating high asynchrony (i.e., species responding dissimilarly through time) reordering where directional changes dominated sample distance increases over but not sites. Progressing low convergence samples decreases time). Moreover, new were more likely be recruited if close relative previously. In contrast, progressing neutral recruitment model, indicating competition between closely related significant component species-species interactions samples. Finally, periodontal treatment did select similar stabilized α-diversity, centered abundance clusters mean, increased community rearrangement. Conclusions Here, we show ecological principles define explain evolution outcomes specific microbial progression. All composition. characterized asynchrony, dominated, convergence, model recruitment. model.

Diversity, connectivity and negative interactions define robust microbiome networks across land, stream, and sea

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Янв. 10, 2025

In this era of rapid global change, factors influencing the stability ecosystems and their functions have come into spotlight. For decades relationship between complexity has been investigated in modeled empirical systems, yet results remain largely context dependent. To overcome we leverage a multiscale inventory fungi bacteria ranging from single sites along an environmental gradient, to habitats inclusive land, sea stream, entire watershed. We use networks assess microbiome robustness identify fundamental principles stability. demonstrate that while some facets are positively associated with robustness, others not. Beyond positive biodiversity x relationships find number "gatekeeper" species or those highly connected central within networks, proportion predicted negative interactions universal indicators robust microbiomes. With potential promise engineering address challenges human ecosystem health properties microbiomes for future experimental studies may enhance emphasize features beyond additional characteristics such as adaptability should be considered these efforts.

Destabilization of the Bacterial Interactome Identifies Nutrient Restriction-Induced Dysbiosis in Insect Guts

Microbiology Spectrum, Год журнала: 2022, Номер 10(1)

Опубликована: Янв. 5, 2022

Stress-associated dysbiosis of microbiome can have several configurations that, under an energy landscape conceptual framework, change from one configuration to another due different alternating selective forces. It has been proposed-according the Anna Karenina Principle-that in stressed individuals are more dispersed (i.e., with a higher within-beta diversity), evidencing grade dispersion as indicator dysbiosis. We hypothesize that although leads microbial communities terms beta diversity, these not necessarily differently (within-beta but they form disrupted networks make them less resilient stress. To test our hypothesis, we select nutrient restriction (NR) stress impairs host fitness does introduce overt selectors, such toxic compounds and pathogens. fed polyphagous black soldier fly, Hermetia illucens, two NR diets control full-nutrient (FN) diet. were dysbiotic because strongly affected insect growth development, inducing significant microscale changes physiochemical conditions gut compartments. established new compared FN-fed guts similar dispersion. However, driven by deterministic induced reflected rarefied, structured, connected bacterial interactomes. These results suggested while cannot be considered consistent unhealthy state microbiomes, capacity community members maintain network connections stability their incapacity sustain holobiont resilience homeostasis. IMPORTANCE Changes diet play role reshaping animals, associated microbiome. Although studies reported on effects specific contents diet, regarding altering networking response limited. Our showed poor determine states reduction weight size, increase times for developmental stage. Moreover, lead compositional diversity interaction properties communities. study adds component understanding ecological processes dysbiosis, disentangling consequences is manifested disruption rather than diversity.
