Struktur Komunitas Ikan Karang di Perairan Kota Sorong, Papua Barat Daya, Indonesia

Jurnal Kelautan Tropis
Reef fish are one of the biota that are sensitive to environmental changes. Their abundance and diversity are supported by good coral reef conditions. This makes them a bioindicator of coral reef conditions.

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

Remote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

Widespread Bomb Fishing in Indo‐Pacific Archipelago Revealed Through Machine Learning Accelerated Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
AI‐accelerated passive acoustic monitoring reveals extensive bomb fishing within the Spermonde Archipelago, with annual incidents numbering in the thousands. ABSTRACT Bomb fishing is recognised as the most destructive fishing practice that can be performed in our oceans.

Deep blueprint: A literature review and guide to automated image classification for ecologists

Journal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, EarlyView.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

Comparisons between abundance estimates from underwater visual census and catch-per-unit-effort in a patch reef system [PDF]

Marine Ecology Progress Series, 2012
ABSTRACT: Methods of underwater visual censuses (UVC) and catch-per-unit-effort (CPUE) areboth commonly used to estimate abundance of fish stocks. While each method is subject to certainbiases, in theory they should produce related measures of fish abundance for a specific site at agiven point in time, for species targeted by both methods.

Analysis of reef fish community structure as a basis for identifying potential OECM in the Kilwaru-Kiltay Area, East Seram, Indonesia [PDF]

BIO Web of Conferences
Reef fish communities are widely used as sensitive bioindicators of coral reef ecosystem condition and provide an ecological basis for area- based conservation planning, including Other Effective Area-based Conservation Measures, yet site-specific ...
