Evidence for a by‐product mutualism in a group hunter depends on prey movement state

Functional Ecology, Volume 38, Issue 10, Page 2123-2138, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Group‐hunting animals have been shown to engage their prey in long pursuits (kms) to increase capture success, but the evidence for this is limited to a few terrestrial species.

Symbiotic cleaning relationship between a sailfish (Istiophorus platypterus) and remoras (Remora osteochir)

Journal of Ethology
Abstract The symbiotic relationship between remoras and their hosts is difficult to comprehensively evaluate, as hosts may experience both benefits and disadvantages from their interaction with remoras.

Impact of mercury released from permafrost on food safety in Switzerland

Food Risk Assess Europe, Volume 2, Issue 4, October 2024.
ABSTRACT Climate change has caused the permafrost to thaw, releasing the previously sequestered mercury into the environment. Mercury has the ability to convert to methylmercury, a bioaccumulative neurotoxin. Exposure occurs in humans through the ingestion of contaminated food and it is associated with adverse health effects.

Short communication: Identification of by-catch species of tuna purse seiners in Iranian waters of Oman Sea [PDF]

, 2018
One of the most visible direct impacts of fishing is the capture of non-target species, known collectively as by-catch. By-catch includes species that are unwanted and discarded (discards) and species that are retained and sold (byproduct) (Stobutzki et

Measuring deoxygenation effects on marine predators: A new animal‐attached archival tag recording in situ dissolved oxygen, temperature, fine‐scale movements and behaviour

Methods in Ecology and Evolution, Volume 15, Issue 8, Page 1360-1379, August 2024.
Abstract Global climate‐driven ocean warming has decreased dissolved oxygen (DO) levels (ocean deoxygenation) leading to expansions of hypoxic zones, which will affect the movements, behaviour, physiology and distributions of marine animals. However, the precise responses of animals to low DO remains poorly understood because movements and activity ...

Post-Release Survival of Sailfish (Istiophorus platypterus) Captured on Commercial Pelagic Longline Gear in the Southern Gulf of Mexico [PDF]

, 2007
To estimate post-release survival of sailfish caught incidentally to regular commercial pelagic longline fishing operations in the southern Gulf of Mexico targeting mixed swordfish and tunas, ten pop-up satellite archival tags were deployed for ten days ...

The vulnerability of sharks, skates, and rays to ocean deoxygenation: Physiological mechanisms, behavioral responses, and ecological impacts

Journal of Fish Biology, Volume 105, Issue 2, Page 482-511, August 2024.
Abstract Levels of dissolved oxygen in open ocean and coastal waters are decreasing (ocean deoxygenation), with poorly understood effects on marine megafauna. All of the more than 1000 species of elasmobranchs (sharks, skates, and rays) are obligate water breathers, with a variety of life‐history strategies and oxygen requirements.

Phylogenetic patterns in fossil and living billfishes (Istiophoriformes, Istiophoridae): evidence from the Central Mediterranean

Papers in Palaeontology, Volume 10, Issue 4, July/August 2024.
Abstract Study of the relationships of fossil and living billfishes is crucial for understanding the ecological drivers that control their biodiversity through time and how distributional patterns of extant populations may be affected by current abiotic events.

Temporal changes in lengths of Dolphinfish revealed by sampling at sportfishing tournaments in the southeastern United States

North American Journal of Fisheries Management, Volume 44, Issue 3, Page 660-676, June 2024.
Abstract Objective Our objective was to use sportfishing tournament data to determine whether sizes of Dolphinfish Coryphaena hippurus have been changing in the western North Atlantic (WNA) over recent decades. Methods We sampled North Carolina, South Carolina, and Florida marine sportfishing tournament landings for Dolphinfish lengths.
