The article examines the most known popular poplar found in central Alberta, the Parkland or Grove Belt. The poplar, accordingly, is approximately 20,000 square miles and is mainly covered with trees, shrubs and grasslands. It is allegedly named Parkland or the Grove Belt because the area has once looked like a park. It is believed that the area is formed by climates themselves, composing of long, cold, dry winters, and a growing season of about four months. The area is also marked by low humidity, strong sunlight and frequent high winds. These situations, when taken together, are considered responsible for the development and persistence of the major plant communities. They have been pointed as the main culprit behind the production of the chief classes of soils found in the region.

Studies conducted on four crop species tomato, maize, cotton and field beans; Comparison between the day-site experiment conducted on the crop species; Discussion on effects of various climatic factors on the four crop species.

The article presents a study on the brousse tigrée vegetation patterns on the laterite plateau surfaces of southern Niger. It was found out that these patterns were the result of linear differentiation of woodland and bareland as a response to shallow soil conditions in a zone of limited rainfall that give rise to intense root competition. Moreover, the patterns are self-perpetuating with the proportions of woodland and bare ground being related to total rainfall. Relative to this, large new areas could be created by termite activity and the original differentiation is initiated through this manner despite of the stability of the main elements of the patterns.

This article discusses a study which aims to describe the chronological patterns of emergence of Capsella and Senecio in the field in relation to some climatic variables in order to elucidate some of the factors which result in these patterns. The researchers conducted a viability test of seeds, soil tests and statistical treatment. The study indicated that most Capsella seeds show a pronounced innate dormancy which is removed by a period of cold treatment on the imbibed seeds. It also found that Senecio seeds do not show a stratification requirement and show less initial innate dormancy than Capsella.

The article presents a study on the vegetation and climate in the uplands of south western Uganda during the later Pleistocene period. The study involves the identification of the plant remains to explain the origin and development of these swamps and lakes. The cores of these bodies of water underwent pollen analyses to provide details of the vegetation and climatic history. It was found out that the climatic and vegetation histories are correlated with the pollen diagrams of Kenya despite that the detailed comparisons with these and with the later Pleistocene chronology of the high latitudes is reserved for other events that needs extensive evidence.

The article focuses on the determination of the occurrence of calcifuge species on shallow soils in the British Isles. The characterization of ferns and flowering plants as calcicole or calcifuge ecologists relied almost entirely on the correlation of soils analyses with estimates of plant frequency. However, the climate favouring the leaching of shallow soils in the British Isles, will result in a low incidence of droughting as well as the high regular rainfall, Moreover, the findings based on the various experiments show severe phosphorus deficiencies were induced in calcifuges on soils which supported mixed calcicole-calcifuge vegetation in the field.

The article presents a survey of the changes observed in Laminariaceae found in the Island of Arran in Scotland from 1952 to 1955. Decrease in the crop of Laminariaceae from 1952 to 1953 and from 1954 to 1955 was observed. The decrease in the crop is suggested to follow a trend in other areas of Scotland particularly during a peak in 1947 followed by progressive decreases in 1953 which would be succeeded with increases on the following year. Laminaria saccharina Lamour remained the dominant species throughout the study period. This species underwent considereble seasonal and perennial changes.

The article discusses the hydro economy of vegetation of the Campos Cerrados in Southern Brazil. Huge areas of Southern and Central Brazil is covered with savanna-like aspect, Campos Cerrados. The wonder on the presence of stunted and poor vegetation is attributed to dry climate, human intervention particularly yearly burnings, is determined by testing water economy of Campos of Emas as the purpose of research. Soil depth over Humid-hot condition is great with underground water level occur at 17-18 meters. The abundant of water in soil and undisturbed areas with forest of hygrophytic character led to conclude that Cerrados at Ema is a fire-climax. Applying agricultural and silvicultural methods endangers fertility of soil in humid conditions may cause Cerrado's infertile land.

The article reports on the study conducted on the vegetation of Western Palestine. Studies show that the flora of the Mediterranean territory in Palestine is affected by man to the extent that the climax vegetation is strongly intermixed with the lower successional stages. They found that the primary vegetation covers extensive stretches within the territory. The segetal vegetation constitutes a series of floristically and ecologically fairly well-defined plant communities that may add important features to the character of the vegetation areas considered.

The article offers information on the vegetation of Mauritius. An analysis was conducted to determine the structure and development of the upland climax forest in Mauritius. The status of upland forest is presented, followed by comparison on the general structure of tropical forests found in British Guiana, Sarawak, and Southern Nigeria. The formation and change in the forest is connected to the Tropical Lower-Montane Evergreen Rainforest of Burtt Davy. It is mentioned that climax forest is revealed to have developed from a phanerophytic heath community.

The article accounts the topography, climate and vegetation of New Zealand. The country's climate is composed of several distinct facies revealed by the vegetative cover, but not so clearly by the spectra. Study shows that the spectra for the western and the eastern portions of South Island are similar, but dissimilar in their climates and vegetative covers. It gives the spectra of different association groups. It concludes that the spectra of major taxonomic groups do not always agree with those of the normal spectrum. This suggests that biological spectra do not give a more accurate picture of plant climates than would careful summaries of major formations.

The article discusses the ecology of Breckland and its position, topography, climate, soil and vegetation. The author explains that Breckland is a physiognomic unit that has a vegetational features determined by a dry soil in a dry climate. He mentions that Breckland's surface contain gentle slopes without the steep-sided coombs. The author compares the meteorological data for Valencia in Ireland, Cambridge in Breckland and Berlin. He also mentions that Breckland's surface has small patches and as a whole, it is overlaid with glacial deposits.

The article explains how the rainfall of the dry season of the Gold Coast, Queensland, must be considered as one main factor that limits the growth of cacao. It is claimed that those important cacao-producing areas have been suffering from a degree of wetness for the dry season of over 10 units, an amount revealed if the rainfall of the dry season and not that of the whole year is to be considered. The dry season then becomes an influential factor on many aspects of the growth and cultivation of the crop because fruiting, vegetable growth, Sahlbergella attack, soil cultivation, and manuring are all undermined by the season.

Examines the impact of climate on the landscapes and the modes of human occupancy and livelihood in China. Role of climate in the production, distribution and exchange of produce; Influence of climate on methods of agriculture; Differentiation of zones of cultural features.

The article describes the technique in which buried magnets were utilized for marking experimental plots. Posts or pegs driven into the ground marks the experimental plots and modifies the habits of grazing animals and the microclimate. Relative to this, they are liable to be taken away by vandals. Small markers can be utilized to minimize these effects but could be difficult to find again. This may be found by searching with a magnetometer and a compass. It was concluded that magnets are useful markers when posts above the ground are undesirable.
