Endangered White‐Clawed Crayfish (Austropotamobius pallipes) eDNA Detection Suggests Agriculture May Exert Significant Pressure on the Species

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
Northern Ireland white‐clawed crayfish (Austropotamobius pallipes) eDNA Survey 2024 expanded the species' distribution despite demonstrating the species to be in unfavorable conservation status. ABSTRACT The white‐clawed crayfish (Austropotamobius pallipes) is IUCN Red‐Listed as globally endangered being in unfavorable (bad) status in both the UK and ...

Modelling erratic dispersal accounting for shifting ice flow geometries: A new method and explanations of erratic dispersal of the British–Irish Ice Sheet

open access: yesJournal of Quaternary Science, Volume 40, Issue 6, Page 944-957, August 2025.
ABSTRACT Glacial erratics are geologically distinctive rocks transported away from their source area by ice sheets and deposited in lithologically different bedrock areas. They have attracted much scientific curiosity with >24 000 observations across the British Isles.

Intraspecific Functional Trait Variation and Coordination in Schizachyrium scoparium

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Understanding how traits vary within and between populations of plant species and how axes of trait variation describe trade‐offs in plant function is necessary to fully realize the utility of functional traits in ecological restoration. We investigated intraspecific trait variation among five populations of Schizachyrium scoparium (little bluestem), a

Till Texture in Drumlins [PDF]

open access: yesJournal of Glaciology, 1981
AbstractDrumlin till has often been described as clay-rich. Drumlins in Ontario are composed of sandy till. Additional examples from north-eastern North America show that sandy till is common in drumlins.It is suggested that the widely accepted association between drumlins and clay till was fostered by the use of such terms as “boulder clay” and ...

Some Impacts of Overgrazing by Reindeer in Finnmark, Norway

open access: yesRangifer, 1996
Some impacts of reindeer grazing on Finnmark's landscape are briefly described. Information on the impacts was gathered mostly by surveying 17 sample transects in the field, often 90 m in length; as well as by examining other localities in Finnmark ...

The Shape of Drumlins [PDF]

open access: yesJournal of Glaciology, 1959
The lemniscate loop, previously employed in the approximate generic description of the shapes of erosional drainage basins, is shown to bear a close genetic relationship to streamlined forms. This is illustrated by comparison with the shape of airfoils, the snowdrift and certain eggs.
