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 ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.
