The Brecon Beacons of central and southern Wales offer the opportunity to explore a range of geomorphological processes, particularly those relating to the rapid climate changes associated with the period subsequent to the Last Glacial Maximum. The mountains present some of the best preserved evidence in the British Isles of the interplay between glacial, periglacial and paraglacial processes, associated with conditions of marginal glaciation, and provide the most southerly evidence of Younger Dryas/Loch Lomond Stadial glaciation of Britain. The absence of evidence for landscape evolution in the region prior to the Last Glacial Maximum has recently begun to be addressed through insights derived from the subterranean geomorphology of limestone found in the south of the region. As one of the key sites of the early Industrial Revolution, the Brecon Beacons also preserve a unique landscape of anthropogenic (or even anthropocenic) geomorphology associated with large scale coal and iron extraction.read more

Scale-dependent effects of fine sediments on temperate headwater invertebrates
TL;DR: In this paper, the authors surveyed macroinvertebrates and superficial fine sediments at two spatial resolutions (reach-and patch-scale) in tributaries of the River Usk, a temperate, montane catchment in rural Wales (U.K.).

Onset of Late Palaeozoic glacio-eustasy and the evolving climates of low latitude areas: a synthesis of current understanding
V. P. Wright,S. D. Vanstone +1 more
TL;DR: In the early Asbian, the Gondwanan ice sheet was highly sensitive to orbitally forced variations in solar insolation and the resultant sea-level oscillations had an approximate 100 ka periodicity as discussed by the authors.
