Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

open access: yesSedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes

open access: yesEcology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Impact of Hypoxia on the Community Structure of Benthic Macroinvertebrates of Lagos Lagoon, Nigeria

open access: yesJournal of Applied Sciences and Environmental Management, 2016
Study of the Lagos lagoon was conducted for two years to investigate the impact of hypoxia on the benthic  macroinvertebrates. Water and benthic samples were collected monthly along the study stretch and analysed in a standard laboratory.

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

The Affects of acid mine drainage on the water quality, and benthic macroinvertebrate and fish population in streams in Maryland [PDF]

open access: yes, 1972
The purpose of this study was to measure and evaluate relationships between populations of benthic macroinvertebrates and fish, as well as variations in water quality in streams affected by acid Mine drainage.
