AbstractIn the Nahoni Range of the northern Ogilvie Mountains, Yukon Territory, Canada, dissection channels are most markedly developed on valley sides facing the north and north-east. The extent of slope channelling is controlled by intensity of insolation and its influence on persistence of snow and ice. Upon the cooler north- and north-east-facing slopes, snow and ice remain well into midsummer; melt water is released over a long period and its discharge is restricted to narrow rivulets. In contrast, snow and ice on the warmer west- and south-facing slopes melt rapidly during the late spring months. The scree on these valley sides moves down-slope as a more or less uniform mass of water-saturated detritus.

Abstract The present surge of the Donjek Glacier on the north-east side of the St Elias Mountains, first noticed in 1969, is producing a number of morphological effects adjacent to the glacier in the terminus area. Although the effects of the surge are minimized by the lobate form of the glacier terminus, several types of push structure, erosional forms and certain drainage changes are being produced. These forms are similar to older forms close to, or on, the Neoglacial maximum moraine. It is considered that the similarities suggest that surges may have occurred throughout most of the Neoglacial period.

Seven species of the amphipod genus Ericthonius are described and figured from the North-east Atlantic and associated seas and a key to their identification is provided. West Atlantic material is also considered where relevant to the taxonomy of East Atlantic species. Two species are re-established after a long period of submersion in synonymy, and one species new to science is described. The previous confusion in the literature of some of the species is discussed, and a synonymy of species described in key works is provided.

Summary. Chlorsulfuron, triasulfuron and metsulfuron methyl were applied at recommended and double recommended rates in 5 trials (1990–96) in winter (May–July) or late spring (October) to a heavy textured soil in the Central Highlands of the north-east grain region of Australia. Treated areas were sown back to sorghum in the following spring, to sorghum and sunflower in summer, and to chickpea in the following autumn. Shoot dry matter at 3 weeks after emergence and grain yields were measured. Soil residue levels of chlorsulfuron were measured by bioassay following herbicide application and at sowing of sorghum and chickpea. Rainfall and temperature were recorded for each fallow period. The recropping intervals ranged from 2.5 to 4.1 months for spring sorghum, 2.5 to 9.3 months for summer sorghum and sunflower, and 5.7 to 11.7 months for chickpea. The shorter intervals were a consequence of the late spring applications. The spring sorghum crops were significantly injured by all herbicides, when chlorsulfuron residues at sowing ranged from 1.67 to 2.1 ng/g in the surface 15 cm. Summer sorghum, sunflower and chickpea were unaffected by any herbicide treatment, except the covered (rainfall excluded) metsulfuron methyl treatment. Despite the differences in recropping intervals and fallow rain, all summer sorghum crops were sown into low chlorsulfuron residues (ranged from non-detectable to 0.2 ng/g). Similarly, residues measured at chickpea sowing ranged from non-detectable to 0.1 ng/g. The lack of crop response and the low levels of detected herbicide residue indicate that in this environment these herbicides dissipate rapidly, and the safe recropping intervals are much shorter than currently recommended on herbicide labels.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.
