Beyond Exponential Decay: How Biphasic and Delayed Decay Dynamics Shape Marine eDNA Dispersal
Ecology and Evolution, Volume 16, Issue 1, January 2026.We used a multiprong approach with a literature review of eDNA decay experiments, an experimental study of empirical decay patterns, and high‐resolution Lagrangian particle tracking to quantify how different decay patterns drive eDNA dispersal at two contrasted locations in the Bay of Biscay, Northeast Atlantic.

A STUDY ON THE GROWTH AND AGE OF THE JACK MACKEREL IN THE EAST CHINA SEA
NIPPON SUISAN GAKKAISHI, 1964 In the present paper, growth and age of the jack mackerel, Trachurus japonicus (TEMMINCK et SCHLEGEL), are estimated, based upon the. ring mark on scale stripped fromthe 610 fish caught by purse seine operated by a single boat in the East China Sea during the three years from 1957 to 1959.

The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns
Environmental DNA, Volume 8, Issue 1, January–February 2026.Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Scientia Marina, 2004 The killer whale is an opportunistic top-predator of ecosystems worldwide and its diet varies locally and seasonally, which is reflected in diverse feeding behaviours associated with its prey.

The Effect of Feeding Stimulants Added to Formulated Diet on Growth of the Jack Mackerel Trachurus japonicus [PDF]
, 2013 The effect of feeding stimulant mixture on feeding activity, grouth, feed efficiency and other physiological conditions of jack mackerel Trachurus japonicus were asseyed by using the formulated diet based on brown fish meal or casein.

Spatial approximation of jack mackerel eDNA concentration.
, 2016 Based on CytB gene copy number in a 2 μL template DNA solution at the 47 sampling station, spatial variation of jack mackerel eDNA in west Maizuru Bay was estimated by approximation.

Trophic interactions in northern Chile upwelling ecosystem, year 1997
Latin American Journal of Aquatic Research, 2014 A food web model is constructed to describe predator-prey interactions, community structure and trophic flows in northern Chile upwelling ecosystem (18°20'S, 24°S), for the year 1997. The model is built using the Ecopath with Ecosim software version 6.4,
