Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 1011-1021, June 2026.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.

Cryoprotectant systems and cold tolerance of insects inhabiting central Yakutia (Russian Far East)

open access: yesEuropean Journal of Entomology, 2016
Strong tolerance of freezing is an important strategy for insects living in extremely cold regions. They produce highly effective cryoprotectant systems consisting of ice-nucleating proteins and polyols, which enables tolerable freezing of the body fluid.

Catalysts for change: Museum gardens in a planetary emergency

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 401-410, March 2026.
Natural history museums are often seen as places with indoor galleries full of dry‐dusty specimens, usually of animals. But if they have gardens associated with them, museums can use living plants to create narratives that link outside spaces to inside galleries, bringing to life the challenges facing biodiversity.
