Large Number Of Collections Research Articles

The role of radiology in provenance research - experiences from the collaboration between radiology and anatomy at the University of Rostock and future perspectives.

Worldwide, the study and examination of human remains and the circumstances of their acquisition for anatomical collection have received great interest. As part of provenance research projects, a large number of collections are being investigated to determine whether the human remains have been acquired in a correct or unlawful way because the people could have been killed in order to be used as "anthropological objects" for research purposes and to become so-called "specimens". These topics have also been addressed by the Institute of Anatomy at the University Medical Center Rostock. The role of radiology in this interdisciplinary project will be presented using selected examples.The anatomical collection at the University of Rostock includes 40 human skulls, 14 plaster casts, 6 Egyptian mummy heads, and 1 full-body mummy. In addition to the examination by a historian, an anthropologist, and forensic pathologists, additional computed tomography was carried out on nine skulls and the full-body mummy. Micro-computed tomography was also carried out on seven skulls in order to enable a look behind the mummification material and tissue remains.(Micro-)computed tomography was able to close diagnostic gaps and the results presented some rather unexpected findings.Due to interdisciplinary collaboration, individual fates could be determined, which provided information about the individual's life and death circumstances. None of the examined individuals showed evidence of colonial-era injustice or the use of violence that would have led to their inclusion in the collection. (Micro-)computed tomography was a valuable addition to this provenance research project. · Computed tomography enhances interdisciplinary provenance research projects.. · Computed tomography enables a non-destructive examination of human remains.. · The future of research and presentation of human remains will increasingly be virtual.. · Steinhagen I, Brinker U, Kolbe V et al.

In short, the library has made available all those facilities and services to its patrons to enable them take their academic endevours to new heights. The resluts obtained from the study validate the above mentioned claims and at the same time point out some areas that need improvement.

Genotypic diversity and patterns of variation in a germplasm material of Ethiopian mustard (Brassica carinata A. Braun)

The amphidiploid species Brassica carinata A. Braun is believed to have originated in the plateaus of Ethiopia and has been cultivated there as an oilseed crop since antiquity. The species possesses agronomically important genes of rare occurrence. Although there is a large number of collections in Ethiopia, information on the extent of their genetic diversity is very limited. Thirty-six accessions of ecologically diverse regions were tested at three locations and multivariate analyses on 13 morphological and seed characters were performed. There was generally a large amount of divergence in all characters. Geographic isolation of genes, however, was not observed. Both principal component and cluster analyses disclosed complex relationships among the accessions and characters. Accessions with potential genes of interest to improve earliness, yield components and oil and protein contents have been identified. Length of growing period and yield components contributed most for divergence and clustering pattern. Oil, glucosinolate and protein contents also varied among the accessions but not so much between clusters. Increasing protein in high-glucosinolate genotypes reduced oil content and should be more efficient in genotypes of low-glucosinolate genetic background.

Identification and classification of aromatic rices based on DNA fingerprinting

Aromatic rices are preferred by the consumers all over the world due to its flavour and palatability. Although a large number of these collections are available, little systematic analysis of genetic diversity has been carried out. With the objective of identification and classification of aromatic rice genotypes, RAPD profiling was employed using 58 random decamer primers. Most of these primers (96.5%) detected polymorphism among the genotypes. Of the 465 amplified bands, 314 were polymorphic. Cluster analysis based on Jaccard's similarity coefficient using UPGMA grouped all the traditional tall, photosensitive, low yielding, long grained ‘basmati’ aromatics together. The short grained aromatic cultivars, formed a different cluster with high level of average similarity among themselves. The dendrogram based on 58 primers was highly similar to that based on 10 and 15 primers with matrix correlation (r) of 0.88 and 0.91, respectively. This suggested that a set of 10 primers can be employed for an initial assessment of genetic diversity in a large number of collections. All the rice genotypes included in the study could be distinguished from each other at the level of 19 to 186 polymorphic bands between individuals in pair wise comparison over all the 58 primers. Probability of identical profiles by chance suggested that about 1041 genotypes can be unambiguously differentiated by RAPD fingerprints obtained by 58 primers. A diagrammatic mode of presentation of DNA fingerprints of the aromatic rices based on 10 of the informative primers was developed.

Performing Arts Museums and Collections in India

In India, the performing arts are inseparable from the country’s ancient religious and cultural traditions. They are thus reflected in a large number of collections not necessarily created to focus on the performing arts as such, but rather to display the tangible evidence of a history unparalleled in variety and richness. Shovana Narayan is an award‐winning Kathak dance virtuoso who has captivated audiences at home and abroad. She has published extensive research in the field of dancing and is visiting lecturer at the Theatre Wissenschaft of the University of Vienna.

The Habitat and Distribution of Meesia triquetra in North America and Greenland

Meesia triquetra (Richt.) Aongstr. occurs in rich fens having surface waters with high pH and calcium concentrations. The present day distribution of M. triquetra in North America and Greenland is documented from Alaska and British Columbia east to Newfoundland and Ellesmere Island, N. W. T., and south to northern California in the west and Pennsylvania in the east. A large number of collections have been madefrom the mountains andfoothills in Alaska, British Columbia, and Alberta; also notable are the many collections from the Great Lakes area. All Quaternary subfossil records lie in the same geographic area as extant records except for one station in Iowa and another in southern Ohio, both of which lie south of the present-day range. Meesia triquetra (Richt.) Aongstr. can be distinguished from the other two North American species of Meesia by a distinct three-ranked leaf arrangement, acute leaf apices, denticulate leaf margins, and dioicous sexual condition. Meesia triquetra is a rich fen indicator species of high fidelity. In the boreal region it grows in carpets in open mires, including the flarks of patterned fens and floating mats of pond margins. Meesia triquetra can also be found in hollows of alkaline, swampy Betula and Salix woods. In the Arctic, M. triquetra grows on calcareous seepage slopes and at the bases of hummocks in wet meadows. This moss is considered uncommon and strictly limited in its distribution by habitat availability (Odgaard 1988; Slack et al. 1980). I had opportunity to outline the habitat and distribution of this rare indicator species in North America as part of a larger work on the population biology of M. triquetra. Meesia triquetra usually occurs in fens with high species richness. Among the most abundant moss species found in these fens are Aulacomnium palustre (Hedw.) Schwaegr., Bryum pseudotriquetrum (Hedw.) G.M.S., Drepanocladus revolvens (Sw.) Warnst., D. vernicosus (Mitt.) Warnst., and Tomenthypnum nitens (Hedw.) Loeske. It has also been found as isolated plants in carpets, below lawns of Sphagnum angustifolium (Russ.) C. Jens. and hummocks of S. magellanicum Brid., although this assemblage is rare. When present, M. triquetra can be abundant but is usually found as stems intermingled in carpets of Drepanocladus revolvens (Sw.) Warnst. and Scorpidium scorpioides (Hedw.) Limpr. Other indicator species of these mires are Calliergon triTABLE 1. Chemical parameters of surface waters from fens in which Meesia triquetra occurs.

The morphology and distribution of Xenopus vestitus (Anura: Pipidae) in Central Africa

Studies on the collections of the Musée Royal de l'Afrique Centrale and the Institut Royal des Sciences Naturelles de Belgique have shown that Xenopus kigesiensis Tinsley, 1973 is synonymous with X. vestitus Laurent, 1972. Previously unrecognized representatives of the species have been found in the museum collections and these considerably enlarge the known geographical distribution of X. vestitus. Samples have been recorded principally from highland areas adjacent to the western Rift in Zaire, Uganda and Ruanda; comprehensive morphological analysis demonstrates relatively limited intraspecific variation throughout the known range.The distribution of X. vestitus overlaps with that of three other Xenopus taxa: X. laevis victorianus, X. bunyoniensis and a new Xenopus species. There is evidence from a large number of collections from widely separated localities that X. vestitus is commonly sympatric with X. l. victorianus. On the other hand, it is postulated that X. vestitus has recently invaded Lake Mutanda, Uganda, and has replaced the original X. bunyoniensis population during the past 30 years. The museum record provides a potential origin of this invasion: X. vestitus populations are well documented at Rutshuru, only 25 km downstream from Lake Mutanda.A comparison of the morphological characters of X. vestitus, X. l. victorianus and X. bunyoniensis is presented to provide information on the systematic relationships and possible ecological adaptations of the overlapping species.

Revision of the genusOmmatobrephus Nicoll, 1914

The paper deals with the revision of the genusOmmatobrephus Nicoll, 1914 based on the study of the different type specimens and a large number of collections from different hosts and localities. This genus consists of four species; generotypeO. singularis Nicoll, 1914;O. lobatum Mehra, 1928 with many synonyms;O. megacetabulus Simha, 1958 andO. bengalensis Mukherjee and Ghosh, 1968.

Chromosome numbers in some Indian angiosperms—II

In this work 23 species belonging to 12 genera distributed within Cruciferae, Caryophyllaceae and Compositae (tribe Gnaphalieae) have been studied. Each species has been studied from a large number of collections often coming from diverse sources.

Taxonomic Notes on Myxomycetes, IV

Lister (Mycetozoa ed. 3: 217. 1935) says of this species: "It is closely allied to Oligonema flavidum, of which it appears to be hardly more than a variety." Hagelstein (Mycologia 31: 341. 1939; 32: 377. 1940) notes its resemblance to A. nitens, from which it differs in its more golden color and the netted capillitium, in addition to the characteristic markings of the latter. Careful examination of a large number of collections of both 0. flavidum and 0. nitens and of a smaller but adequate number of collections of Calonema aureum failed to disclose any that I should regard as intermediate. In addition to the constant presence of a capillitial net, and the characteristic capillitial markings of the Calonema, both capillitium and sporangium wall turn a bright pinkish orange when a weak solution of potassium hydroxide is added to a mount, whereas the only effect of this solution on any Oligonema is to cause a slight intensification of the yellow-brown color of the sporangium wall.

Studies in the Nearctic Freshwater Amphipoda, III

Descriptions of most of the older species of freshwater Amphipoda of the eastern United States being inadequate, it was essential that material from the type localities be examined in order to fully understand the species. As such material was not available, the author undertook to make collections at as many of these type localities as could be located. As a result, most of the species were obtained at the type localities, or so near as to leave little doubt as to the determinations. In addition, in the regions traversed, a large number of collections were made which add to our knowledge of the distribution of these species. This paper is a report on these collections, together with some material collected by other persons and examined by the author.

The Water Bugs of Dewponds

DEWPONDS have attracted much attention on account of the beliefs that they remain full and even show a rise in water level during periods of drought, dew being the responsible agent, and that some of them date back to prehistoric times. Pugsley (1939) has shown the fallacy of both these beliefs. A good deal of time has been devoted to investigating how dewponds obtain their water, but, except for some observations on the snail fauna (Hurst, 1920; Reid, 1892, etc.), little work appears to have been done on their biology, although they are particularly suitable for ecological work, being uniform in general features and many in number, so that any ecological conclusions can be based on a large number of collections.

The Seasonal Abundance and Distribution of the Pelagic Young of Teleostean Fishes Caught in the Ring-Trawl in Offshore Waters in the Plymouth Area

A large number of collections were made with the 2-metre stramin ring-trawl in the years 1924, 1925 and 1926, to study the vertical distribution of young fish. Seeing that all these collections were made in exactly the same way, it was considered that they would form a good basis for a study of the quantitative differences in abundance of the different species at various times of the year. Accordingly, after 1926 the collections were supplemented in-1927, 1928 and 1929 by oblique hauls with the ring-trawl fishing at the same depths as those fished in the serial hauls in the study of the vertical distribution, that is the net was fished successively at the six different depths during half-an-hour's haul for 5 minutes at each depth. The results given in this report are all based on daylight catches.
