Comparing Aquatic Environmental DNA Collection Methods Across a Diel Cycle in a Lotic System
Water samples were collected over 25 h from the Tangipahoa River, Louisiana, using active and passive environmental DNA methods to detect fish assemblages. Active sampling involved collecting water samples at hourly intervals for 25 h, whereas passive sampling deployed a stationary filter for 25 h.

Spatial, diel, and seasonal changes in the fish community structure of a Mexican tropical estuary
To extend our knowledge about spatial and temporal variations in the structure of estuarine fish communities, diel samplings (collections every 2 h) were carried out every two months over a one-year period in two different habitats (vegetated and ...

ABSTRACT Major threats to marine species and ecosystems include overfishing, invasive species, pollution and climate change. The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts.

ABSTRACT Marine species distributions reflect fundamental ecological interactions, and analyzing their patterns helps identify key drivers of change and enhances our understanding of shifting habitats and ecosystem responses. In response to ocean warming, marine species exhibit a range of accommodations, including tolerance to thermal changes and ...
