Pelagic Larval Duration and Population Structure of a Widely Distributed Amphidromous Fish in the Indo‐Pacific Region

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

Mitigating Fish Entrainment With Fish Protection Screens at Water Pumping Sites

open access: yesFisheries Management and Ecology, Volume 32, Issue 6, Page 542-560, December 2025.
ABSTRACT The Murray‐Darling Basin (MDB) is one of the most regulated and fragmented river systems in Australia. The basin's extensive river infrastructure development has supported growing water demands for irrigation, industry, domestic, and electricity production, but increased use of pumps for water diversion threatens aquatic species and ...

Old methane fuels modern river food web

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1721-1731, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Dominant ecological paradigms provide theoretical frameworks for two basal sources of carbon to riverine food webs: carbon fixed by algae and submerged macrophytes (autochthonous) and carbon fixed by terrestrial vascular plants that enters aquatic ecosystems as litter ...

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

open access: yesEcological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.
Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.
