Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Temporal and seasonal trends of bovine tuberculosis in the Irish cattle population (2008–2024)

Veterinary Record, EarlyView.
Abstract Background Bovine tuberculosis (bTB) has substantial impacts on the Irish cattle industry. Between 2016 and 2024, its burden increased in Irish cattle. As an initial step towards understanding drivers of this increase, we explore long‐term trends in measures of bTB burden and cattle demographics in Ireland. Methods Using data from 2008 to 2024,

Seeds of discord: Unravelling family conflict, parenting, and child externalizing behaviours

British Journal of Developmental Psychology, EarlyView.
Graphical Abstract This study found reciprocal associations between angry parenting and child externalizing behaviours, with maternal effects emerging earlier and more strongly than paternal effects. Interparental conflict was not a reliable predictor of change. Results highlight the value of targeting maternal parenting in efforts to prevent childhood

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

Boreas, 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 ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

Boreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...
