Carryover of Bracken Fern Toxins into Food, particularly into Water, Goat Milk and Goat Cheese from Swiss Alpine Farms

open access: yesFood Risk Assess Europe, Volume 4, Issue 4, October 2026.
Abstract In recent years there has been growing interest in bracken toxins, in understanding their effect, occurrence and prevention. Most of these substances are glycosides and are therefore highly water soluble and mobile. They can transfer to drinking water or via livestock to milk and meat, thereby potentially posing a health risk.

Selenium reverses Pteridium aquilinum-induced immunotoxic effects

open access: yesFood and Chemical Toxicology, 2011
We have previously shown that bracken fern (Pteridium aquilinum) has immunomodulatory effects on mouse natural killer (NK) cells by reducing cytotoxicity. Alternatively, it has been demonstrated that selenium can enhance NK cell activity. Therefore, the aims of the present study were to evaluate if ptaquiloside, the main toxic component found in P ...

Tracking and modelling native woodland expansion in the Scottish Highlands using LiDAR

open access: yesJournal of Applied Ecology, Volume 63, Issue 9, September 2026.
Forest restoration projects should utilise the new LiDAR‐based pipelines to effectively map young trees, assess whether targets are met, and plan further action. Notably, the Scottish Government is now commissioning a national airborne LiDAR scan, providing a unique opportunity to upscale our algorithms to create national woodland expansion databases ...

Ecological Costs of Waiting to Restore Ecosystem Engineers: The Case of Giant Tortoises in the Galápagos Islands

open access: yesConservation Letters, Volume 19, Issue 5, September/October 2026.
ABSTRACT In the Galápagos Islands, giant tortoises (Chelonoidis spp.) engineer terrestrial ecosystems. Endemic tortoise lineages have been lost from Floreana and Pinta Islands, resulting in ecosystem shifts, with tortoise population restoration currently being considered using hybrids that include ancestry from the now extinct C.
