The article presents a study about the studies on grasslands of the Western Ghats in India. This paper focuses on the ecological conditions, topography, climate, soil and vegetation in this area covering the period from June 1953 to December 1955. Various regions were surveyed giving the phytosociological data of the grasslands in Bombay, Khandala, and Lonavla. The methods applied in this experiment are described. Behavioral succession of vegetation were studied related to the biotic factors. Results of the study are discussed in brief.

The article presents a study on the soluble salts in dune sands from Blakeney Point in Norfolk, England. Ten soil samples were taken in each of the seven dune areas to a depth of 3 cm. The samples were mixed together and then dried to about 100 degree Celsius. The mixtures were shaken occasionally for a week and filtered with the use of Whatman 541 filter papers. It was found out that the total concentration of soluble salts is greatest in the embryo dunes near the sea with approximately twice the concentration in the sand hills that is a few yards farther from the tide mark.

When the scheme of morphological subdivision propounded is applied to Western Europe, the Central Massif of France appears as a physiographic province with a unity of major relief type and structural evolution. The geographical regions within this province have two other important features in common: they have a similar history and the majority are characterized by a "mountainous centrality" with regard to the rest of France. It is the purpose of this paper to examine the emergence of the general patterns of road and rail communications in these regions.

The article presents abstracts of papers on foreign vegetation including an analysis of the plankton of a Californian river, freshwater algae from the mountains of Southern Norway and a visit to Kunadiyaparawita Mountain.

The article presents a study on the light reaching the ground vegetation in the high forest phase and its relation on the differences in forest structure of two selected sites, where one is on the slopes of Mount Andes and the other is at the extreme western edge of the Amazon basin. The authors state that their observations and analysis have enabled them to associated some of the differences between the two forests with differences in light climate. They mention that the interactions between light and other factors, specially root competition, may be very important. They believe that future studies on light as an ecological factor in tropical forests will most productively be aimed to the reaction of individual species to light at various stages of growth.

Colluvial mantles on the mountains of southwestern United States are believed to have formed during colder climates associated with the last glaciation. They imply mean temperatures 10-11°C. lower than those of today and a depression of the timber line by 1,300-1,400 meters. Evaporation rates were about half the present values and by estimating runoff it is possible to reconstruct the full-glacial hydrologic budget of Pleistocene closed lakes. Precipitation was eighty to ninety percent of present values and there was no glacial pluvial. Pollen data can be reconciled with the proposed cold dry climate which has modem homoclimes at higher altitudes and latitudes. [ABSTRACT FROM AUTHOR]

Explains the origin of the linear topography of the Palouse region in Washington. Reasons for geographic distribution; Impact of erosion or deposition with alignment of topography; Importance of wind behavior and materials with linear hills.

This article presents a study which investigated the vegetation of the Wabag Region in the New Guinea Highlands. A brief background on the study areas, a review of previous related literature and a description of the study's methodology are provided. The study found that the Wabag region consists of uninhabited forested ridges and densely inhabited valleys with non-forest vegetation. It is noted that sites that are geographically close together tended to resemble one another more closely than did remoter sites at the same altitude.

This article presents a study which investigated the vegetation of Cader Idris in Merionethshire, Wales. A brief background on the study area, a review of previous related literature and a description of the study's methodology are provided. The study found four major physiognomic/ecologic units that comprise Cader Idris. A comparison of the community-types on Cader Idris with those described in other areas indicates that there is a high degree of similarity between the vegetation of widely separated upland areas in Great Britain.

The article focuses on the study of limestone, and acid parent materials on the vegetation of the Santa Catalina Mountains, Arizona. The study conducted a comparison of the limestone, and acid soils vegetation through detailed studies in the 1830 to 2130 meter elevation belt. It mentions that conducted elevation of the Cercocarpus breviflorus on limestone has contrasted the limestone with pine-oak. It was concluded that the contrast of limestone vegetation with other soils, including acid soils, could be striking with areas including marginal forest, and woodland climates.

The article presents a study on the three-line of the Cairngorm Mountains of the northeast Scotland. The study suggested that the three-line posed questions on the previous positions of the post-Glacial period. The Cairngorm Mountains were dominated by Pinus sylvestris, and most of the mountains' portions are artificial. According to the author, the forest margins were reduced by people during the 16th, and 19th centuries. Wind exposure, and biotic pressure prevent the forest to make an upward extension.

The article presents ecological notes on the upland forests of Cameroon Mounting in West Africa. According to the author, the chief objective of the visit of the Cambridge Botanical Expedition to the mountains to obtain information on the floristic composition, structure and ecological relationships of the upland forests and to compare them with the lowland forest. Cameroon Mountain is an active volcanic mountain located on the coast of the Bight of Biafra, and is the highest mountain in West Africa, according to the author.

The article presents the microclimatic observations on a ridge cleared of forest cover from May 1 to September 30, 1961 to rate the effect of topography on surface climate and on botanical processes in Ontario, and compares these microclimatic observations to observations made across a forested ridge of shape and orientation. The authors also cite the associated phenological and radial growth observations. Air and Piche evaporation are also measured at a height of 30 cm above the ground surface. It is determined that the twice-weekly phenological observations during May and September reveal a trend of flowering and other features of plant development to occur earliest on the ridgetop, next on the south slope, and then on the north slope.

The article discusses the study which investigates the impact of wind on the vegetation of arctic-alpine regions. It is averred that in arctic and alpine regions, wind is frequently a significant factor in holding the growth and character of the vegetation. Arctic vegetation is characteristically flat-growing so that most of the leaves lie in a layer where wind accelerates are shortened by the halting action of the ground's surface. The wind affects the temperature of arctic-alpine plants during daytime where air becomes warmed in a thin layer near the ground and cooler at greater heights. The researcher concludes that the potent effect of wind on arctic-alpine vegetation is generally a result to that special sensitivity of plant growth to wind.

The article focuses on the survey which assessed the environment of Carneddau, a group of mountains in Snowdonia, Wales. The survey described the environment of a mountain massif in Snowdonia, the Carneddau, under topography, climate, rocks and soil, and land management. It revealed that the sub-mountain vegetation is divided broadly into grassland, heath and bog, which occupy most of the zone below the potential altitudinal tree-limit, but above the limits of enclosed land. The survey also found out that the land management practices appear to be causing economic degeneration of the hill-lands and moor-burning is perceived as a particularly harmful custom.

The article provides information about the condition of vegetation in the northern coastal plain and hills of Jedda, Saudi Arabia, which extends into the eastern slopes of the Red Sea mountains. It particularly discusses the characteristics of rainfall in the region, and describes the main topographical features of the vegetation area. The eight plant associations of the region's vegetation were also described. Those associations include the Olea-Tarchonantghus association, the Acacia mellifera association, the associations of the coastal plain, and the associations of halophytes.

The article discusses ecological observations on Mt. Hanang, an extinct volcanic mountain in East Africa. The observations were conducted from February 4-15, 1946, and specimens from 187 plants and bird skins collected have been deposited in the East African Herbarium, the Kew Herbarium and the National Herbarium in Pretoria, South Africa. There are three distinguishable summits at the mountain as a result of volcanic activity and subsequent erosion. These include the Main Peak, the highest point, Werther Peak and the Three-ridged Peak.
