Within the past 10 to 15 years, White-tailed Deer (Odocoileus virginianus) have extended their geographical range to include most of northern Alberta. In the boreal forest they are most abundant in well-drained upland habitat. We report the occurrence of unusually large numbers of deer seen in a large fen complex in the west side of the Athabasca River Caribou range in northeastern Alberta. Further, we report an observation that suggests that deer may be using arboreal lichen (old man’s beard; Bryoria spp. and Usnea spp.) as a winter food in this region. We discuss the potential ecological ramifications of this observation for Woodland Caribou (Rangifer tarandus caribou) in northeastern Alberta.

Type Area

In the type area the Ludlow Rocks generally have been divided into Lower Ludlow Shales, Aymestry Limestone, Dayia Shales and Whitcliffe Flags in upward sequence. The Dayia Shales are characterized by the presence of enormous numbers of Dayia navicula (J. de C. Sowerby). This preponderance of D. navicula in the shales immediately above the Aymestry Limestone has caused a tendency to regard beds in other localities containing this fossil as being on the same stratigraphical horizon in spite of the character of the accompanying fauna. In two recent papers on the Ludlow Rocks of the Welsh Borderland (Straw, 1937, and Earp, 1938) it has been shown that D. navicula ranges through at least 3,000 feet of strata, occurring commonly throughout this great thickness and outlasting more than one change of fauna. Although, in this area, the brachiopod ranges from the zone of Monograptus nilssoni into the Upper Ludlow it has not hitherto been recorded below the Aymestry Limestone in Shropshire. This gap in our knowledge is now filled by the discovery of specimens in Lower Ludlow Shales exposed in a small quarry 40 yards north-east of Stokewood Cottage, which is on the west side of the railway line a little over a mile south of Craven Arms. The quarry shows about 15 feet of nodular shales with thin limestone seams. The commonest fossils are Chonetes laevigata (J. de C. Sowerby), C. minima (J. de C. Sowerby), and Stropheodonta filosa (J. de C. Sowerby) which occur in large numbers on some of the bedding surfaces. Other fossils are Stropheodonta euglypha (Dalman), Delthyris sp., Orthoceras sp., Dalmanites sp., and a plectambonitid. Dayia navicula seems to be confined to a thin layer on the north side of the quarry. Graptolites referable to Monograptus cf. chimaera occur fairly commonly. About 400 yards in a south-easterly direction another small quarry exposes Conchidium Limestone which is about 170 feet stratigraphically above the beds in the first quarry.

AbstractAmetropus neavei McDunnough populations apparently inhabit only large rivers. In the Athabasca River of northeastern Alberta, Canada, the species has an univoltine life cycle, with some overlap of generations. There appears to be an extended emergence period (June and July), the nymphs are found in flowing water at depths greater than 0.5 m, and the population is almost entirely small-particle detritivores.

AbstractThe ‘Burials and Identity’ team of the Desert Migrations Project carried out two main excavations in the 2009 season, at the monumental Garamantian cemeteries of TAG001 and TAG012, by the Taqallit headland. In addition, a detailed survey was made of cemeteries and other sites on the west side of the Taqallit headland, to set the two main cemetery excavations in context. A total of over 2,100 individual burials was recorded in this small area of a few square kilometres. This cemetery survey was combined with further research on the well-preserved foggara systems in this area, which originate at the escarpment among the cemeteries and run in a north-westerly direction towards the valley centre, where some additional Garamantian settlement sites were also located. The foggara research also involved excavation at four locations to try to elucidate issues relating to the dating of these.A total of 22 burials was investigated at TAG001, an imposing cemetery of stone-built stepped tombs that had been badly damaged by illegal bulldozing in the 1990s. Although these had been subjected to robbing at some point in the past, many preserved considerable parts of the skeletons buried within and some surprisingly complete artifact groups. Of particular importance are a series of Garamantian necklaces in ostrich eggshell, carnelian and glass beads, which we were able to lift in perfect sequence and restring. At TAG012, about 2 km north of the Taqallit headland, we excavated an area of a mudbrick cemetery, exposing 12 square/rectangular tombs. Two further burials were excavated at the dispersed cemetery TAG006, in both cases involving tombs that had an interesting stratigraphical relationship with foggara spoil mounds.

Aquatic Mammals

This paper describes how knowledge mobilization evolved during a study that assessed a proposed increase in industrial water withdrawals from the Athabasca River in northern Alberta, Canada, and potential impacts on a suite of freshwater semi-aquatic mammals in the broader ecosystem. The oil sands region in northeastern Alberta faces various pressures that require rapid knowledge mobilization and decision making, while still acknowledging ecological sensitivities immediately downstream in the Peace-Athabasca Delta (PAD) in the Wood Buffalo National Park. Data were acquired using a multi-faceted approach, including literature reviews, acquisition and synthesis of raw data, and interviews with local knowledge holders. The final outcome of the study was then contextualized relative to elements of knowledge mobilization: (1) research, (2) dissemination, (3) uptake, (4) implementation, and (5) impact. Knowledge mobilization was easiest to quantify for the first two elements, yet was still present in varying forms in the latter stages. The cultural importance of beavers, muskrats, river otters, and mink for communities associated with the Athabasca River and the PAD allowed for increased engagement during all stages of the research process, which then facilitated the co-production of potential solutions among different organization and perspectives.

Invented Traditions

On June 17th 2011 graffiti artists transformed the West side of the Monument of the Soviet Army (MSA) in Sofia, Bulgaria. MSA comprises part of a spatial environment where the invented traditions of the Bulgarian state interact and compete. The art of provocation challenges those invented traditions and opens up the potential for alternative readings and discursive practices of the past and present, contrary to the official political and NGO discourse. As such it subverts ideological symbols in a fashion similar to the carnivalesque. The graffiti art provides the potential to reevaluate, bridge and connect a violent past with an equally violent present, as well as pose questions about the future. It signifies the presence of history and politics in everyday life.

With the filling up of Gatun and Mira Flores Lakes, water lettuce (Pistia stratiotes, Linné) and water hyacinth (Eichornia crassipes, Solms.) rapidly increased in numbers until large areas became completely covered by them. Masses of these plants would become detached and float about in these lakes. It was found necessary to destroy these “floating islands,” not because they were serious mosquito habitats, but because they interfered with navigation and the operation of the spillways. The water lettuce is the habitat of the very specialised larvae of Mansonia, of which titillans is the commonest member. Knab (1913) and Busck (comments appended to Mr. Knab' paper) refer to the changes in the mosquito fauna brought about by the rapid increase in Pistia. Both Mansonia titillans. Walker, and Aëdomyia squamipennis (Lynch-Arrib.) Theo., have been collected by me in very large numbers since 1912, and to-day Mansonia is the dominant species caught in the army barracks on the west side of the canal. Knab expressed the opinion that perhaps measures would have to be taken to destroy the Pistia habitats; now that we have found Anopheles larvae in them, this prophesy comes closer home.

The site of the following discovery is a gravel-pit owned by Mr. George Young on the west side of the Fosse Way, midway between Slaughter Bridge and Stow Bridge, and 1½ miles NNE. of Bourton-on-the-Water. In the course of digging, during the past few years, a series of circular ditches has been observed in the gravel on three sides of the pit. Unfortunately it has not been possible to plan the ditches, of which there seem to be three. Recently a ditch was cleared out for about a quarter of its length, and appeared to have a diameter of about ioo ft. The ditch was V-shaped, 6 to 6½ ft. wide and 3 to 5 ft. deep, with a stiff red clay filling, in the upper part of which were embedded some oolite stones. The stones occurred over the middle of the ditch or towards its inner side, and may possibly have once lined the sides of the ditch, and slipped out of position as the ditch filled up. A section of the ditch with the stones is shown in pl. LIII, fig. 1, taken after the top soil, about 12 in. deep, containing late Roman pottery, had been cleared away.
