Towards the fully automated monitoring of ecological communities

Ecology Letters, Год журнала: 2022, Номер 25(12), С. 2753 - 2775

Опубликована: Окт. 20, 2022

Abstract High‐resolution monitoring is fundamental to understand ecosystems dynamics in an era of global change and biodiversity declines. While real‐time automated abiotic components has been possible for some time, biotic components—for example, individual behaviours traits, species abundance distribution—is far more challenging. Recent technological advancements offer potential solutions achieve this through: (i) increasingly affordable high‐throughput recording hardware, which can collect rich multidimensional data, (ii) accessible artificial intelligence approaches, extract ecological knowledge from large datasets. However, automating the facets communities via such technologies primarily achieved at low spatiotemporal resolutions within limited steps workflow. Here, we review existing data processing that enable communities. We then present novel frameworks combine technologies, forming fully pipelines detect, track, classify count multiple species, record behavioural morphological have previously impossible achieve. Based on these rapidly developing illustrate a solution one greatest challenges ecology: ability generate high‐resolution, standardised across complex ecologies.

Abstract Temporal variation in eDNA signals is increasingly explored for understanding community ecology aquatic habitats. Seasonal changes have been addressed using sampling, but very little known regarding short‐term temporal that spans hours to days. To address this, we filtered marine water samples from a single coastal site Denmark every hour 32 h. We used metabarcoding target both fish and broader eukaryote diversity evaluated this community. Results revealed species richness (15–27) class (35–64) across the h of further sampling efforts needed reach different levels saturation. Relative read frequency data eukaryotes indicated clear diel change composition, with communities detected during daylight versus dark hours. The abundance our reflected biological rather than stochastic variation, since replicates taken at same were more similar each other those Our compositional results dynamic community, static pool eDNA—even few showed daily pattern relative abundances, uncoupling suggest profiles day can provide valuable information reflecting changes, least highly mobile organism groups.

Biological invasions, resulting from human activities, exert substantial impacts on ecosystems worldwide. This review focuses marine invasive alien species (IAS) in Europe, examining the current state, proposing strategies to address problem, and offering recommendations for enhanced management. Effective management of biological invasions relies accessible, accurate data inform decision-making. Information systems such as European Alien Species Network (EASIN), Aquatic Non-Indigenous Cryptogenic (AquaNIS), World Register Introduced Marine (WriMS) provide comprehensive databases IAS, but their sustainability requires long-term maintenance, continuous updates, support. Most countries lack specific monitoring programs standardization improvement methods are needed. Port plays a vital role early detection new arrivals, recent advancements molecular techniques show promise effective IAS monitoring. Risk screening tools commonly employed rank taxa based invasiveness potential regions, variations protocols can yield inconsistent results. impact assessments highlight resource competition, novel habitat creation, predation primary mechanisms negative biodiversity, while creation habitats represents key mechanism positive impacts. Preventing introductions is critical, measures ballast water treatment implemented reduce likelihood introductions. However, understanding introduction pathways remains uncertain many IAS. Eradication control efforts have limited success, emphasizing need biosecurity measures. Climate change, especially ocean warming, intensify native ecosystems. In climate change hotspots, some tropical aliens may, however, compensate loss thermally sensitive natives with similar traits. Therefore, it imperative consider interactions between developing conservation strategies.

Invasive alien species (IAS) adversely impact biodiversity, ecosystem functions, and socio-economics. Citizen science can be an effective tool for IAS surveillance, management, research, providing large datasets over wide spatial extents long time periods, with public participants generating knowledge that supports action. We demonstrate how citizen has contributed across the biological invasion process, especially early detection distribution mapping. However, we recommend could used more assessing impacts evaluating success of management. does have limitations, explore solutions to two key challenges: ensuring data accuracy dealing uneven coverage potential recorders (which limits dataset's "fit purpose"). Greater co-development stakeholders will help us better realize its process ecosystems globally while meeting needs participants, local communities, scientists, decision-makers.

Navigating Methodological Trade‐Offs in eDNA Metabarcoding Biodiversity Monitoring: Insights From a Mediterranean Watershed

Molecular Ecology Resources, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Environmental DNA (eDNA) metabarcoding technologies promise significant advances in biodiversity monitoring, yet their application requires extensive optimisation and standardisation. Recent research demonstrated that increased sampling analytical efforts are needed to improve estimates, though fully optimising study designs is often hindered by resource constraints. Consequently, researchers must carefully navigate methodological trade-offs design effective eDNA monitoring studies. We conducted a water survey of vertebrates Mediterranean watershed identify key factors influencing species richness composition estimates. examined the impacts using high- versus low-capacity filtration capsules, varying levels biological technical replication, pooling PCR replicates before indexing. The primary sources variation identified were capsule capacity site replication across watershed. While within sites also improved effects comparatively smaller. Pooling indexing performed more poorly than analysing them independently. Methodological stronger on terrestrial aquatic species. Based these results, we recommend priority should be given high-capacity multiple sites. Site-level deserves lower priority, especially when filtering large volumes. crucial for detecting rare but balanced with eventually site-level replication. Avoiding important enhance sensitivity Overall, stress importance balancing choices constraints goals, emphasise need assessing different systems.

Опубликована: Авг. 18, 2023

Abstract The deep‐sea is vast, remote, and largely underexplored. However, methodological advances in environmental DNA (eDNA) surveys could aid the exploration efforts, such as using sponges natural eDNA filters for studying fish biodiversity. In this study, we analyzed from 116 sponge tissue samples compared these to 18 water visual obtained on an Arctic seamount. Across survey methods, revealed approximately 30% of species presumed inhabit area 11 were detected via derived alone. These included commercially important Greenland halibut Atlantic mackerel. Fish detection was highly variable across samples. Highest rates found with low microbial activity those class Hexactinellida. different methods also alternate communities, highlighted by only one overlap between Therefore, conclude that can be a useful tool surveying demersal communities it synergises improving overall biodiversity assessments. Datasets form comprehensive baselines seamounts, which turn inform marine management conservation practices regions where are undertaken.
