Mobulid rays feed on euphausiids in the Bohol Sea [PDF]

Royal Society Open Science, 2017
Mobulid rays have a conservative life history and are caught in direct fisheries and as by-catch. Their subsequent vulnerability to overexploitation has recently been recognized, but fisheries management can be ineffective if it ignores habitat and prey ...

Satellite-Based Lagrangian Model Reveals How Upwelling and Oceanic Circulation Shape Krill Hotspots in the California Current System

Frontiers in Marine Science, 2022
In the California Current System, wind-driven nutrient supply and primary production, computed from satellite data, provide a synoptic view of how phytoplankton production is coupled to upwelling. In contrast, linking upwelling to zooplankton populations

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

Environmental variability and krill abundance in the central California current: Implications for ecosystem monitoring

Frontiers in Marine Science, 2023
Krill are a direct conduit between primary productivity and recreationally and commercially important higher trophic level species globally. Determining how krill abundance varies with temporal environmental variation is key to understanding their ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Piscivorous fish patrol krill swarms [PDF]

, 2005
Journal homepage: http://www.int-res.com/journals/meps/Dense swarms of the krill Meganyctiphanes norvegica in the Norwegian Sea were patrolled by large, piscivorous fish, which apparently use the krill swarms as feeding grounds in their hunt for ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Research Progress on Antarctic Krill Products and Their Quality and Safety [PDF]

Progress in Fishery Sciences
Antarctic krill (Euphausia superba) and its products have garnered increasing attention as valuable natural resources because of their rich nutritional profile, particularly that of their bioactive compounds such as proteins and phospholipids.

sampley: A Python package for sampling visual survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Visual surveys are a common method of obtaining data for ecological studies, including studies that develop models (e.g. species distribution models). In the case of transect or non‐transect line surveys, data must often be partitioned into spatiotemporal units (i.e. samples) before being modelled.
