Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Fibrillar‐Type Dermatitis Herpetiformis: An Underrecognized Variant That Is Rarely Associated With Celiac Disease and Lacking Epidermal Transglutaminase Deposition: A Report of Two Cases

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Dermatitis herpetiformis (DH) is a rare, intensely pruritic cutaneous manifestation of celiac disease (CD), typically presenting with excoriated papulovesicular lesions on extensor surfaces. DH is associated with IgA autoantibodies against epidermal transglutaminase (eTG), which form granular immune deposits in the papillary dermis and induce ...

Animal Teachers: Nonhuman Pedagogy and the Question of Deceit

open access: yesEducational Theory, EarlyView.
Abstract Animals as “teachers” of human children and adults is a recurring theme in children's literature, in anthropological accounts of “feral children,” as well as in contemporary practices of animal‐assisted pedagogy, philosophical research, wildlife documentaries, and popular culture.

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

open access: yesThe Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

Seasonality and plasticity in the use of native and introduced plant resources by a large forest parrot

open access: yesIbis, EarlyView.
Human‐induced environmental change is reshaping plant communities, requiring native animals to adapt their foraging behaviour to track and exploit novel food resources. Trees such as pines (Pinus spp.) introduced for plantation forestry outside of their native ranges often become naturalized.

A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

open access: yesIbis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.
