The article outlines recommendations relating to the accurate use of the taxonomic aspects of ecological investigations, which are approved by the Council of the British Ecological Society. The Council hopes that the Flora and Edition which has been used in determining the taxonomic concepts and nomenclature followed in the paper should be stated by contributors to the "Journal of Ecology." The Council also encourages the preservation of material of all the taxonomic units, from each plant community described. Finally, the Council calls on contributors to state the herbarium or herbaria in which his specimens have been deposited.

Specimens of Stenostomum, which could be attributed to either S. anatirostrum or S. bryophilum, from Britain, Kenya and Poland have been described, and compared with published descriptions of similar material collected in Brazil and Finland. It is concluded that 5. bryophilum ought to be regarded as a synonym of S. anatirostrum. S. anatirostrum is a very variable species with a wide geographical distribution. It occurs in aquatic and damp terrestrial habitats. [ABSTRACT FROM AUTHOR]

The article announces the decision of the British Empire Vegetation Committee to discontinue the series of abstracts which have been published in the "Journal of Ecology" since 1928. The intent of the scheme when it started was that authors books and papers on ecology relating to the Overseas Empire should send abstracts of their work to the Committee. It is cited that authors of ecological publications in the Empire have not responded to the scheme and very few authors' abstracts have been received. It offers information on the other sides of the Committee's work.

The article presents evidence for intra-specific competition in field populations of triclads. It stresses thet sessile habit of these plants explains the more satisfactory demonstrations of competition by botanists. The article also notes that the species is widespread in Britain and lives under variable biological conditions. Breeding occurs over most of the year but there are two peaks, a larger one in early spring and another in later summer. It explains that triclad populations in this account illustrate intra-specific competition well through determining the special characteristics of animals and special conditions.

The article presents summaries of several articles that deal with the vegetation of some areas in Great Britain. They are "Blakeney Point in 1914," by F. W. Oliver, "Hydrilla verticillata in Britain," by W. H. Pearsall, "Pilura globulifera in Glamorgan," by M. Y. Orr, "Stratiotes aloides near Criebb," by R. C. Davie and "The Ecology of Knockdow Estate, Argyllshire," by Augusta Lamont. Information on the journals wherein the articles are published is provided, as well as the number of pages of the articles.

The article presents an observation on the lichen ecology of Dorset, England's South Haven Peninsula where a system of sand dunes lives. According to the study conducted by Good, the general succession on the dunes is from dune-grass dominated by Ammophila arenaria to dry Calluna-heath in which the succession comes along with increases in acidity and organic content of the soil. It relates that lichen vegetation of the dunes has one of the most striking features which is the complete transition occurs in the replacement of Ammophila by Calluna. It also provides a comparison with the lichen vegetation of adjacent heaths on Bagshot gravel, and with other dune systems in the country.

The article presents the results of the study obtained by the use of penetrometer in testing the soil hardness of the shore at Whitstable, Kent, in England. The study suggests that the layers of soil surface are composed of two components identified as the ridges and troughs. The ridges are softer than the troughs and the troughs accommodate less water than the exposed ridges. It also conveys the result that the seasonal cycle of changes in soil hardness during the period of exposure do not rely on temperature.

The article describes the study concerning the quantitative morphology and ecology of Eriophorum angustifolium Roth in Great Britain. Eriophorum angustifolium Roth occurs throughout the cool temperate regions of the northern hemisphere as a constituent of the plant communities of bog and damp moorland and as a colonizer of shallow pools on peat and of wet peat surfaces. The study indicates that rhizome measurements vary with soil moisture wherein gravity has some effect on the position of buds and the development of rhizomes.

Information about the summer meeting of the British Ecological Society which was held in Norfolk, England from July 6-13, 1951 is presented. Activities of the meeting include daily expeditions of the societies' members to various parts of Great Britain with ecological interests. Among these were; visit to the Scolt Head Island, in which the general physiography of the area was described by Professor J. A. Steers, and to Ranworth and Upton Broads in the Bure Valley.

The article describes the ecology of several salt-marshes in Great Britain. The depth of clay mud and the height of the dominant vegetation types are shown and the presence of a dense algal covering in the Asteretum and Salicornietum is also indicated. The phanerogamic and algal vegetation in the salt-marshes are described and the algal salt-marsh communities is surveyed. Some of the algal communities surveyed, include sandy Chlorophyceae, Enteromorpha minima, Phormidium autumnale and Fucus limicola.

The article describes the habitats of land Mollusca in Great Britain. The normal food for Mollusca includes decayed remains of the higher plants, fungi, lichens, algae and dead leaves. It is stated that the occurrence of any snail or slug is determined by its history, its geographical distribution and the nature of its habitat. Some of the Mollusca species living in wet places include Agriolimax laevis, Zonitoides nitidus and Pupa anglica while those living in dry places include Helix virgata, H. caperata and H. cartusiana. It discusses the influence of man on Mollusca.

The article presents a study that examined ecological problems relative to the ecology of soil insects on British agricultural lands, with reference to their nature of occurrence and their food relations. It presents a list of common soil insect species found in nine representative areas in Lancashire, Cheshire, Northumberland, and Durham, which shows that the areas are the real habitat in various associations of the soil insects. Moreover, it provides a composite graph of the occurrence of the different feeding groups, phytophagous and carnivorous, on grassland and arable lands, which shows that on all types of agricultural land has a kind of equilibrium built as regards to different insect species.

The article discusses the significance of the distribution of Nardus Stricta, a dominant type of grass species in the hilly parts of Northern Britain, in relation to peat, a carbonized vegetable matter saturated with water. It is stated that Nardus grassland is an important type of vegetation but being a dominant species among plant associations, Nardus is likely to have little relationship. However, the necessity for observing its relation to other types of species is of higher value in terms of its evolution and displacement by herbage. Furthermore, Nardetum occurs typically on peat which will be redistributed from the exposed surface of peat by wind, water, and biologic agents. During redistribution, Nardus form a zone marginal to the mass which will serve as its habitat.

The article discusses the highlights of the annual general meeting of the British Ecological Society on May 23, 1914 held in the Botanical Lecture Theatre at University College in London, England. Several officers were elected including professor F. W. Oliver, W. B. Crump and O. V. Darbishire. A general statement of the financial position of the Society up to December 31, 1913 was presented by the treasurer. Society president, A. G. Tansley, delivered an address citing the Society's achievements.

The article discusses the vegetation and grassland's condition in Great Britain. According to the authors, the country's grassland distribution depend on various sets of conditions including the economic requirements determined by farm practice, the relation between crops and stock and prices obtainable. It says that the grassland has been allowed to take possession in areas where the original natural vegetation has been destroyed by cultivation, deforesting and other processes. Furthermore, the degree of grazing has enabled grassland to supplant the original vegetation.
