A programme of mapping and augering has shown the glacial drifts of central Leicestershire to consist of a basal sand and gravel overlain by a complex succession of tills and interbedded waterlaid sediments. The tills display a transition from materials of predominantly north-western derivation to those of north-eastern derivation. Arguments are adduced by which the succession is correlated with that described by Shotton in Warwickshire, and it is concluded that the vast majority of the drifts belong to the Saalian glaciation. A widespread but discontinuous horizon of sand and gravel is believed to denote a temporary melt phase in the middle of the glaciation, while more limited beds of stoneless silt and clay betoken still-water sedimentation which, south of Leicester, is regarded as the local equivalent of the lacustrine Wolston clay of Warwickshire. Although the bedrock surface over most of central Leicestershire has a form consistent with an origin by normal stream erosion, there remain a number of areas where it is difficult to sustain such an interpretation. At Narborough excavations and augering have revealed virtually the full drift succession cut by a series of normal faults traceable over a distance of at least a mile. Near these faults there is evidence of an enclosed depression scored into bedrock and filled with water-laid drift. Although subsequent to the deposition of the drift, the faults have no surface expression at the present time, the structures being truncated by an early post-glacial erosion surface. Later phases in the post-glacial evolution of the Soar and Wreak valleys are associated with a suite of river terraces which, from their included fauna, span the period of the Eemian interglacial and the Weichselian glaciation.

Large Branchiopod

In this study, we examine, identify, and discuss fossil remains of large branchiopod crustaceans collected from six sites across the Beringian region (north-eastern Asia and north-western North America). Eggs and mandibles from Anostraca and Notostraca, as well as a notostracan telson fragment and a possible notostracan second maxilla, were collected from both paleosediment samples and also from large mammal hair. The remains of large branchiopods and other species that are limited to seasonally astatic aquatic habitats (temporary wetlands) could be useful indicator organisms of paleoecological conditions. Different recent large branchiopod species have very different ecological preferences, with each species limited to specific geochemical component tolerance ranges regarding various salinity, cation, and gypsum concentrations. Our purpose is to bring the potential usefulness of these common fossil organisms to the attention of paleoecologists.

Ficus roxburghii, “Elephant ear fig “or wild fig is one of very popular fruits found growing wild in the hills of North Eastern and North Western Himalayan region. The fruit of wild fig has also been used as medicine by the tribal people of Sikkim and other states of India. Keeping this in view, the present study was conducted at Laboratory of Department of Horticulture, Sikkim University, Sikkim to access the different nutraceuticals properties as nutritional constituent like protein, fat, fibre, carbohydrate and energy value, mineral content viz.Ca, K, Mg, Na, Zn, Co, Mo, Fe, Mn and phytochemical content such as total phenols, flavonoid, ascorbic acid, anthocyanin and total carotenoids of F. roxburghii. The results of present study revealed that fruit of F. roxburghii contains significant amount of nutritional, mineral and phytochemical properties viz. protein (3.00±0.06%), fat (0.13±0.04%), fibre (3.06±0.02%), carbohydrate (90.81±0.44 %), energy value (376.45±1.44), Ca (23.69 ± 1.7), Mg  (73.09 ± 2.1), K (819.64 ± 12.54), Mo (0.58 ±  0.06), Na (6.73 ± 1.2), Zn (0.34 ± 0.10). Fe (26.55 ± 2.8), Cu (4.22 ± 0.20), Mn (7.11 ± 0.11), total phenols (4.13±0.52 mg GAE/ G), total flavonoid (3.10±0.09 mg GAE/ G), ascorbic acid (3.36±0.27 mg GAE/ G), anthocyanin (1.13±0.15 mg GAE/ G) and total carotenoids (0.68±0.10 mg GAE/ G). It may be concluded that the fruit of F. roxburghiiis rich in nutraceuticals and must be incorporated in our balanced diet.

Active-middle alignment and the aoristic drift

In the classification of Romance along a northern–southern continuum the languages which exhibit patterns of active-middle alignment (notably, the HABERE ~ ESSE alternation in the perfect) are also known to have undergone the aoristic drift. This article starts from Smith’s (2016) observation that the north-western oïl varieties have maintained the preterite, while also alternating the two auxiliaries, whereas the north-eastern oïl varieties have lost the HABERE ~ ESSE alternation and undergone the aoristic drift. It is argued that the developments which have occurred in the north-western varieties are not theoretically challenging or unique within the Romània. With respect to the generalization of habere in the north-eastern areas and, less conspicuously, throughout Gallo-Romance, it is claimed that this development was engendered by the rise of a dependent-marking system which follows undifferentiated nominative alignment. It is concluded that the modern Romània exhibits a stronghold of active-middle alignment in a group of central languages, which are essentially head marking.

Two nymphs of the rare Tasmanian grasshopper Schayera baiulus (Erichson), a male and a female, have been discovered in the north-eastern and north-western corners of Tasmania respectively, thus confirming its Tasmanian provenance and suggesting a former wide distribution across the north of the island. The nymphs are described and figured. The female was reared to maturity and the adult genitalia described. The very different environments at the two capture localities are documented. The problems involved in defining the habitat requirements and securing the survival of the species are discussed.

Late Roman

A programme, combining a physical survey, intensive pick-up and geophysics, was carried out over 17 ha around the site of a small late Roman fortification, some 6 km south of ancient Pydna. Although the area is intensively farmed, the pick-up survey proved remarkably successful. Hellenistic occupation was identified and a restricted Roman settlement around the site of the quadriburgium. Surprisingly, a new and large late Roman fortification (c. 3–4 ha), equipped with towers, with a densely occupied interior and ‘extramural’ buildings was also found. The north-eastern curtain was discovered by resistivity surveying, the line of the north-western and south-western sides by intensive survey. Pottery and brick monograms from the new site suggests that it dates to the second half of the sixth or possibly early seventh century. It is argued that the quadriburgium may be the site of ancient Anamon, a station on the coastal road from Thessaloniki to Dion. The newly discovered site, clearly of considerable importance, lay on the north bank of the river Sourvala and probably had direct access to the sea, importing both local pottery and amphorae from the eastern Aegean. Its role may have been to protect the fertile coastline of the Pieria and to provide a secure base for the export of agricultural products to the beleaguered cities and settlements around the Thermaic Gulf.

Results of monitoring of the population ofBlumeria graminisf.sp.hordeiin Latvia in 2009-2010In 2009-2010, random samples of the causal agent of barley powdery mildew were collected in Daugavpils (south-eastern Latvia, Latgale region), Stende (north-western Latvia, Kurzeme region) and Priekuļi (north-eastern Latvia, Vidzeme region). Virulence frequency, complexity and pathotypes were calculated in the pathogen populations. Significant differences of virulence detected by the genesVa1, Va3and Va13occurred among samples of the pathogen population collected in different parts of Latvia. Nei index, Müller's index, Kosman index, Shannon index and Simpson index showed considerably higher diversity in Daugavpils and Stende during 2009-2010. In Daugavpils, the population ofBlumeria graminisf.sp.hordei was particularly characterised by high diversity.

Basal Till

The Quaternary sequence of an area of 120 km 2 , centred on Market Bosworth in Leicestershire, is described. The entire sequence is regarded as the product of the Wolstonian stage. The bedrock surface of the area shows the buried Hinckley valley, which opened southwards into the proto-Soar basin. The first evidence of sedimentation onto this surface in western Leicestershire is the Basal Till which betokens an ice advance prior to the accumulation of the extensive glacio-lacustrine member, the Bosworth Clays and Silts. This proglacial lake is interpreted as being the northern continuation of lake Harrison, which was initiated on the retreat and stagnation of ice, following the deposition of the Basal Till. A readvance of ice led to the deposition of a large sandur represented by the Cadeby Sand and Gravel and followed by a till sequence comprising the Pennine and Chalky Tills of northwestern and northeastern provenance, respectively.

By using morphology, karyology, pollen size, leaf flavonoids, ecological observations, and modification experiments, a new classification of the Galium trifidum group is proposed. Nine taxa in five species are recognized: (1) G. tinctorium, with ssp. tinctorium and sap. floridanum (new comb.) in eastern North America; (2) G. brevipes, a rare species centered in the Great Lakes region; (3) G. trifidum, with ssp. trifidum in northern North America. Asia, and Europe, ssp. columbianum (new comb.) in (north)western North America and (north)eastern Asia, and ssp. subbiflorum (new comb.) and ssp. halophilum (new comb.) in northern North America; (4) G. innocuum in southeastern Asia; (5) G. karakulense in central Asia.New chromosome counts of n = 12 and 2n = 24 are reported for G. tinctorium ssp. tinctorium and ssp. floridanum; and G. trifidum ssp. trifidum, ssp. columbianum, and ssp. subbiflorum.
