Jurassic tracks and HS2: a twenty‐first century journey
Geology Today, Volume 41, Issue 6, Page 234-243, November/December 2025.The biggest UK railway construction site since the nineteenth century has exposed a near‐complete time slice through the entire Jurassic succession of central England. This is yielding a wealth of stratigraphical, palaeobiological and palaeoenvironmental data that is otherwise generally poorly exposed at the present day.

Using palaeoenvironmental DNA to reconstruct past environments: progress and prospects [PDF]
, 2014 Palaeoenvironmental DNA (PalEnDNA) is defined as ancient DNA (aDNA) originating from disseminated genetic material within palaeoenvironmental samples. Sources of PalEnDNA include marine and lake sediments, peat, loess, till, ice, permafrost, palaeosols ...

Archaeometry, Volume 67, Issue 5, Page 1394-1411, October 2025.Abstract This research paper investigated whether elemental analysis can differentiate leather manufacturing from soil contamination and whether soil hydrology and elemental composition impact degradation of leather. Portable X‐ray fluorescence (pXRF) is a quick method for monitoring large‐scale changes and groupings of aggregate inorganic elemental ...

Experimental demonstration of the antiherbivore effects of silica in grasses: impacts on foliage digestibility and vole growth rates [PDF]
, 2006 The impact of plant-based factors on the population dynamics of mammalian herbivores has been the subject of much debate in ecology, but the role of antiherbivore defences in grasses has received relatively little attention.

Effective dispersal of fern spore and the ecological relevance of zoochory
Biological Reviews, Volume 100, Issue 5, Page 2116-2130, October 2025.ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.
