A Museum‐Curated, Voucher‐Backed 12S Barcode Reference Library for Fishes of the Ecuadorian Amazon

Molecular Ecology Resources, Volume 26, Issue 8, November 2026.
ABSTRACT Environmental DNA (eDNA) metabarcoding is an emerging method that promises to expedite and improve biodiversity surveys by identifying species from the genetic material they shed into the environment. eDNA methods offer many advantages over conventional specimen‐based surveys, but their effectiveness hinges on reference libraries, which for ...

Scaffold Hopping Provides Liver X Receptor Agonist With Preference for the β Subtype

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
A scaffold hopping strategy was pursued to enhance the binding pocket engagement and β‐subtype selectivity of liver X receptor agonist 2. The resulting spirocyclic lead compound, (S)‐7, demonstrates superior potency, enhanced potency‐based selectivity for LXRβ, and improved microsomal stability over the existing scaffold.

Reconciling Granular Hydrogel Microstructure and Mechanics via a Temporary Thermo‐Responsive and Cell‐Invadable Matrix

Small, Volume 22, Issue 56, 8 October 2026.
Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.

Spatially asymmetric and temporally dynamic ecological responses to river barrier removal: A global meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
Barrier removal initiates ecological recovery rather than delivering immediate restoration, with responses shaped by spatial context, initial conditions and time since removal. Monitoring should therefore extend beyond the first post‐removal year and, where feasible, continue for at least 5 years, particularly in downstream reaches, while incorporating

Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

Fisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).
