<em><em>The study investigated determinants of marriage stability among married couples in North Central Nigeria. In order to carry out this study, four hypotheses were formulated. An instrument known as “Determinants of Marriage Stability Questionnair (DOMSQ)” was constructed by the researcher and used to collect information from the field. The instrument had content and facial validity and its reliability coefficient is 0.87. The investigator used eight research assistants to administer nine hundred and ninety copies of the questionnaire on the respondents in Kogi and Benue States. Nine hundred and eighty three copies were retrieved from the respondents indicating 99.3 percent return rate. The researcher collated the information got from the field work and the Z statistics was used to test the hypotheses at 0.05 level of significance. The findings showed that, there was no significant difference between male and female married couples in their identification of childlessness as determinant of marriage stability, there was no significant difference between married couples in the urban and rural areas in their identification of sexual satisfaction as determinant of marriage stability, there was no significant difference between old and young married couples in their identification of cultural background as determinant of marriage stability, there was no significant difference between married couples from Kogi and Benue States in their identification of communication as determinant of marriage stability. One of the recommendations is that couples who are faced with the problem of childlessness should seek medical assistance and also be positive about such outcome.</em></em>

The early tabulate coral Lamottia heroensis has been identified from the Ion Member of the Decorah Formation (Upper Ordovician) in northeast Iowa. This extends the stratigraphic range of this species upward from Lower Chazyan to Kirkfieldian, and extends the geographic range from the Vermont-New York border area to include the north-central Midcontinent. Thin section and SEM studies strongly support the contention that the longitudinal pattern of alternating light and dark bands observed in corallite walls reflects a primary structural grain rather than a secondary diagenetic feature.

The few scholars who have specialised upon military architecture in Italy have, very naturally, concentrated their attention on the spectacular work of the thirteenth to the sixteenth centuries, chiefly in Apulia and Sicily, to a lesser extent in the North; Central Italy as a whole, has been neglected, and particularly the neighbourhood of Rome. There alone can the unimpressive fortresses of the early middle ages be seen in abundance, most of them untouched except by natural decay, because they were not rebuilt when their obsolescence became recognised, but abandoned—in a large number of instances, so documents imply, during the fourteenth century. This article is an attempt to trace the course of local development down to 1300, as shown mainly at certain key-sites. The argument rests on a basis of combined archaeological and documentary evidence; the former is limited by the amount of field-work done by my predecessors or by myself, the latter I have derived entirely from the regional historians of the past hundred years. Investigation of sites not yet reported, and of documents not yet searched for relevant information, should eventually lead to a more precise chronology than is now feasible.

A Cambridge expedition was in Svalbard during late June, July and August 1977 and undertook geological field work concerning late Precambrian/Palaeozoic stratigraphy. One party of the expedition completed a small scale exploration drilling contract for a German industrial concern. Members of the expedition were: W. B. Harland (leader, geologist); C. A. G. Pickton (geologist/driller with Party D); N. J. R. Wright (Party D, geologist); K. Swett and D. Johnson (Party A, geologists from the University of Iowa); M. J. Hambrey and P. Waddams (Party C, geologists); S. R. Larter and B. Bowler (Party D, drillers/geoscientists from the University of Newcastle); J. Gammage, R. Hanks, D. Burkitt, P. Doughty, and G. Thwaites (Party B, boat captains and crews). The activities of the expedition were divided into two phases.

Resumen:Antecedentes y Objetivos: En el sureste de México los estudios florísticos, y en particular los que tratan sobre las Hylocereeae, son escasos. Se presenta un estudio florístico taxonómico de las Cactaceae en Tabasco para conocer la riqueza y distribución de sus especies, se generó un listado deespecies nativas y cultivadas y se presenta una clave de identificación de las especies para Tabasco.Métodos: Se consultaron los herbarios CSAT, MEXU, UJAT y XAL, así como literatura taxonómica pertinente para tener una aproximación de la diversidad de Cactaceae en Tabasco. Se realizó trabajo de campo en todos los tipos de vegetación del estado para obtener las muestras necesarias; éstas se depositaron en el herbario UJAT. Con el material colectado y los ejemplares revisados en los herbarios, se realizaron claves de identificación para los géneros y especies registrados.Resultados clave: En Tabasco se registran siete géneros y 14 especies de cactáceas, seis de las cuales representan nuevos registros para el estado. El género Selenicereus es el más diverso, mientras que el bosque tropical perennifolio y el municipio Tacotalpa presentaron la mayor riqueza de especies.Conclusiones: Las cactáceas en Tabasco se encuentran pobremente representadas en comparación con los estados del centro-norte de México; sin embargo, con los estados de Campeche y Yucatán se observa una notoria similitud en cuanto a la riqueza de especies.Palabras clave: endemismo, epífitas, florística, Hylocereeae, nuevos registros.Abstract:Background and Aims: In southeastern Mexico floristic studies, and in particular those dealing with Hylocereeae, are scarce. A taxonomic floristic study of the Cactaceae family in Tabasco is presented to know the richness and distribution of its species, a list of native and cultivated species was generated and a key to identify the species for Tabasco is presented.Methods: The herbaria CSAT, MEXU, UJAT and XAL were consulted, as well as the pertinent taxonomic literature to have an approximation of the taxonomic diversity of Cactaceae in Tabasco. Field work was carried out in all types of vegetation in the state to obtain the necessary samples, which were deposited in the herbarium UJAT. With the samples collected and those reviewed in the herbaria, keys were made for the genera and species registered.Key results: There are seven genera and 14 species of cacti distributed in Tabasco, from which six are new records for the state. The genus Selenicereus is the most diverse, while the evergreen tropical forest and Tacotalpa municipality presented the greatest richness of species.Conclusions: The cacti in the state are poorly represented in comparison with Mexico’s north-central states, but there is a noticeable similarity in terms of species richness with the states of Campeche and Yucatán.Key words: endemism, epiphytes, floristics, Hylocereeae, new records.

Differential Uplift

The surficial glacial features and glacial events of a 13 000 square mile area in northern Ontario are described, based on field work and study of aerial photographs. Ice-laid and glaciolacustrine materials suggest a complex history of stationary ice fronts and glacial lakes during deglaciation. Lakes in the Lake Nipigon and Lake Superior basins inundated large areas. Post-Minong lake stages in the Superior basin intruded far to the north, dammed by ice at the largest moraine, the Nakina. The northern part of this lake was later separated from the post-Minong lake by differential uplift and was named Lake Nakina. After the withdrawal of the ice, Glacial Lake Barlow–Ojibway occupied the northeastern part of the area, and much of it was later overridden by the last glacial readvance. Stratigraphic correlations with radiocarbon dates suggest that the Nakina moraine was built some 9 400 years ago, and that the last glacier ice disappeared before 6 390 years ago.

An earlier paper (Rautenbach 1971) summarized documented distributional data on the smaller mammals in the Kalahari Gemsbok National Park, Republic of South Africa. Since then continued field- work in this Park (e.g. Nel and Rautenbach in press) has yielded more information on the distribution of some previously recorded species,whilst other species have been recorded for the first time. Collecting hasbeen concentrated on two localities in the vicinity of Twee Rivieren, two near Nossob Camp, as well as at Dankbaar in the north-central portion of the Park.

Floristic Data

Knowledge of county floras in Texas is crucial for determining species composition, management, preservation, and restoration across the state. Like most Texas counties, floristic data for Erath County, Texas, is poorly known. The objectives of this investigation were to compile a flora for Erath County, determine the intro-duced, endemic, threatened, and endangered species, as well as make comparisons to the county’s original flora and that of the North Central Texas region. Field work was conducted from September 2003 to December 2009 at 35 sites in Erath County. In addition herbaria were searched to locate specimens from Erath County. A total of 870 species (888 taxa) were identified in 103 families. One hundred forty-four taxa were introduced while 744 taxa were native. Eighteen of the species are Texas endemics. There were two rare plants, Dalea reverchonii and Penstemon guadalupensis, but no threatened or endangered plants were found during the inves-tigation. Four state-listed noxious species were collected during the investigation—Arundo donax (giant reed), Convolvulus arvensis (field bindweed), Tamarix chinensis, and T. gallica (salt-cedars).
