Survey of automatic plankton image recognition: challenges, existing solutions and future perspectives

Artificial Intelligence Review, Journal Year: 2024, Volume and Issue: 57(5)

Published: April 12, 2024

Abstract Planktonic organisms including phyto-, zoo-, and mixoplankton are key components of aquatic ecosystems respond quickly to changes in the environment, therefore their monitoring is vital follow understand these changes. Advances imaging technology have enabled novel possibilities study plankton populations, but manual classification images time consuming expert-based, making such an approach unsuitable for large-scale application urging automatic solutions analysis, especially recognizing species from images. Despite extensive research done on recognition, latest cutting-edge methods not been widely adopted operational use. In this paper, a comprehensive survey existing recognition presented. First, we identify most notable challenges that make development systems difficult restrict deployment Then, provide detailed description found literature. Finally, propose workflow specific new datasets recommended approaches address them. Many important remain unsolved following: (1) domain shift between hindering instrument independent system, (2) difficulty process previously unseen classes non-plankton particles, (3) uncertainty expert annotations affects training machine learning models. To build harmonized location agnostic purposes should be addressed future research.

A conceptual framework to help choose appropriate blue nature-based solutions

Journal of Environmental Management, Journal Year: 2024, Volume and Issue: 352, P. 119936 - 119936

Published: Jan. 12, 2024

Biodiversity loss and climate change have severely impacted ecosystems livelihoods worldwide, compromising access to food water, increasing disaster risk, affecting human health globally. Nature-based Solutions (NbS) gained interest in addressing these global societal challenges. Although much effort has been directed NbS urban terrestrial environments, the implementation of marine coastal environments (blue NbS) lags. The lack a framework guide decision-makers practitioners through initial planning stages appears be one main obstacles slow blue NbS. To address this, we propose an integrated conceptual framework, built from expert knowledge, inform selection most appropriate based on desired intervention objectives social-ecological context. Our follows four incremental steps structure: Step 1 aims identify challenge(s) address; 2 highlights ecosystem services underlying biodiversity ecological functions that could contribute confronting challenge(s); 3 specific environmental context needs set within (e.g. spatial scale will operate within, ecosystem's vulnerability stressors, its condition); 4 provides potential interventions would help targeted considering defined 3. Designed maintain, enhance, recover, rehabilitate, or create by supporting biodiversity, portfolio includes protection (i.e., fully, highly, lightly, minimally protected areas), restorative activities active, passive, partial restoration; rehabilitation function creation), other management measures enforcement regulation). Ultimately, our guides toward versatile cater each rather than imposing rigid, one-size-fits-all model. In future, this integrate socio-economic considerations more comprehensively kept up-to-date including latest scientific information.

The expression 'you need to know conserve' is a well-known cliche among biologists. Documenting the richness of group organisms first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made quantify number species on Earth estimate still unknown science.

Capacity sharing to protect and restore ecosystems and biodiversity

ICES Journal of Marine Science, Journal Year: 2025, Volume and Issue: unknown

Abstract Challenge 2 of the UN Ocean Decade focuses on protecting and restoring marine ecosystems biodiversity as a fundamental requirement to achieve sustainable development. Addressing this challenge requires reliable timely information ecosystems. To this, academic, government, private groups should engage in process co-design that aims facilitate decision-making at local national level, agree common interoperable practices for collection curation biology ecosystem information. Implementing flow data enable management human activities development will require sharing capacity. An all-hands-on-deck effort help us ensure better future ourselves. A positive step would be identify minimum essential ocean variables can serve multiple relevant regional international frameworks link harmonize required (i.e., including Convention Biological Diversity Kunming-Montreal Global Biodiversity Framework, United Nations Framework Climate Change Paris Agreement, Beyond National Jurisdiction International Seabed Authority, Conservation Antarctic Marine Living Resources, Intergovernmental Science-Policy Platform Ecosystem Services, deep fisheries policies). key strategy is support build existing networks observation. With information, communities nations understand manage how they use life also report progress toward Sustainable Development Goals.

Contrasting the contributions of 12S eDNA metabarcoding, visual surveys and anaesthetic collections to the historical regional diversity of cryptobenthic and conspicuous fish

Journal of Fish Biology, Journal Year: 2025, Volume and Issue: unknown

Published: April 19, 2025

Abstract Taxonomic gaps in community biodiversity assessments are now commonly addressed by combining traditional monitoring methods and environmental DNA (eDNA) metabarcoding, widely recognized for having the ability to uncover rare cryptic diversity. However, only a few studies have assessed efficacy of this novel technique detecting cryptobenthic fishes tested limitations incomplete genetic reference availability historically neglected component fish communities. Our goals were (i) compare conspicuous detections 12S eDNA visual surveys anaesthetic collections, (ii) emerging regional diversity patterns against long‐term historical record Gulf California. Despite adding new local references 36 fishes, metabarcoding detected seven taxa. Visual provided similar results, highlighting collections as primary source, with 57 recovered. Conspicuous had an equal highly complementary contribution surveys. When contemporary from all methods, we recovered 43% 16% relative records. The spatial structure differed expectations showing no differences richness nor composition between Northern Central study highlights that their structuring driven distinct factors compared fishes.
