The genus Bathyporeia has featured in many reports on the ecology of sandy beaches, yet little is known of the annual reproductive cycles of the species in British waters. Watkin (1938,1939a, b, 1941, 1942) has studied the taxonomy and aspects of the ecology of the genus, and more recently Salvat (1967) has described the annual reproductive cycle of B. pilosa Lindstrom, B. pelagica (Bate), B. sarsi Watkin and B. guilliamsonia (Bate) on the west coast of France. The present report is the result of an investigation into the vertical distribution and annual reproductive patterns of B. pilosa and B. pelagica on a sandy beach at Ynyslas, Cardiganshire. Whilst enabling comparisons to be made with Salvat's data, this study also forms the basis for an investigation into the ecophysiological complex of B. pilosa and B. pelagica.

AbstractSurface melting of High Mountain Asian debris-covered glaciers shapes the seasonal water supply to millions of people. This melt is strongly influenced by the spatially variable thickness of the supraglacial debris layer, which is itself partially controlled by englacial debris concentration and melt-out. Here, we present measurements of deep englacial debris concentrations from debris-covered Khumbu Glacier, Nepal, based on four borehole optical televiewer logs, each up to 150 m long. The mean borehole englacial debris content is ≤ 0.7% by volume in the glacier’s mid-to-upper ablation area, and increases to 6.4% by volume near the terminus. These concentrations are higher than those reported for other valley glaciers, although those measurements relate to discrete samples while our approach yields a continuous depth profile. The vertical distribution of englacial debris increases with depth, but is also highly variable, which will complicate predictions of future rates of surface melt and debris exhumation at such glaciers.
