Ecosystem engineers and functional dominance: when species loss matters for ecosystem function

Oikos, EarlyView.
Understanding when and why species loss affects community function in natural communities remains an open question in ecology. Recent cross‐system analyses have shown that functional dominance is associated with whether species loss matters: in communities dominated by few high‐performing species, lost species contribute little to function.

Check list of the marine commercial and reef fishes of Belitung Timur, Bangka Belitung Islands, Indonesia

Aceh Journal of Animal Science, 2018
Marine fish community is very sensitive to environmental changes. So the number of species, abundance, and biodiversity index can be used as a reference to assess the quality of the aquatic environment.

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

Advanced Science
Coral reef ecosystems are among the most biodiverse and ecologically significant marine habitats; however, the carbon storage potential of these ecosystems and how corals and reef‐dwelling fish participate in carbon cycling remain largely unexplored.

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.

Fish assemblages on fringing reefs in the southern Caribbean: biodiversity, biomass and feeding types

Revista de Biología Tropical, 2014
Reef fish assemblages in the Caribbean are under increasing pressure from human activities. Inadequate enforcement of legislation coupled with unreliable and data-poor landings in Tobago have led to the unregulated exploitation of reef fish for decades ...

Associated Of Coral Reef With Reef Fish In Northern And Southern Gili Air Island And Gili Trawangan Island Lombok

E3S Web of Conferences, 2018
Damage to coral reef ecosystems is a major problem on the islands of Gili Air and Gili Trawangan. This will have an impact on the presence of reef fish in the area.

Efficient and Accurate Spatio‐Temporal Population Monitoring of Mobile Animals Using Drones and Computer Vision

Remote Sensing in Ecology and Conservation, EarlyView.
Drones and computer vision offer an efficient way to estimate animal populations over localized areas, but surveys often require stitching many overlapping images together. If animals move during the survey, traditional orthomosaic‐based counting methods become unreliable, with some animals appearing in multiple locations while others appear not at all,

Improving Demographics and Conservation of Fishes Through Multi‐Frame Individual Distinctions by Size (MIDS)

Remote Sensing in Ecology and Conservation, EarlyView.
MIDS (Multi‐frame Individual Distinctions by Size) is a new software package for improving how fish populations are assessed using stereo‐video data. By using the length, error and statistical inference of measurements, MIDS distinguishes individuals across multiple video frames and autonomously removes repeat observations, regardless of when the ...
