There is currently no detailed classification and description of plant communities in Khutse Game Reserve (KGR), Botswana, using phytosociological techniques. The main aim of this study was to classify and describe plant communities in KGR. Classification and description of plant communities will help in understanding the plant ecology of KGR. Braun-Blanquet sampling method was applied in 91 stratified random relevés. Nine plant communities were identified and classified using Modified TWINSPAN which is contained in JUICE program. The results showed that there was a statistically significant difference in percentage cover of herbaceous plants between the different plant communities. Schmidtia pappophoroides-Stipagrostis uniplumis and Heliotropium lineare-Enneapogon desvauxii communities had higher cover (%) of herbaceous plants than other communities. Catophractes alexandri-Stipagrostis uniplumis community had the highest cover (%) of shrubs. There was no statistically significant difference in plant species diversity (Shannon-Wienner Index) and species evenness between plant communities, but there was a statistically significant difference in plant species richness between the different plant communities. Dichrostachys cinerea-Grewia flava community, Senegalia mellifera subsp. detinens-Maytenus species community and Catophractes alexandri-Stipagrostis uniplumis community had lower number of species, whereas Vachellia luederitzii var. retinens-Grewia flava community had the highest number (46) of plant species. This study will help the Department of Wildlife and National Parks (DWNP) to develop an updated and informed Management Plan for the reserve, which takes cognizance of the plant ecology of the reserve.

Four major themes can be identified over the period 2008—2009: (1) the increasing use, sophistication and resolution of remote sensing techniques and the application of these methods to assessment of biomass, C-balance and biosphere-atmosphere interactions; (2) continued interest in dynamic change processes affecting individual species and plant communities, and the changing proportions of tree, shrub and herbaceous components; (3) the nature, impact and management of fire; and (4) increasing awareness of the importance of soils and soil moisture in shaping the nature and distribution of vegetation, particularly at local scales.

The Stability

Abstract. In multi-species communities the stability of a system is difficult to assess from field observations. This is the case for example for competitive interactions in plant communities. If a mathematical model can be formulated that underlies the processes in the community, a community matrix can be constructed whose elements represent the effects of each species onto every other (and itself) at equilibrium. The most common competition model is the Lotka-Volterra equation set. It contains interspecific competition coefficients to represent the interactions between species. In plant community ecology several attempts have been made to quantify competitive interactions and to assemble a community matrix, so far with limited success. In this paper we discuss a method to use pairwise interaction coefficients from experimental plant communities to analyse feasibility and stability of multi-species sets. The approach is contrasted with that of Wilson and Roxburgh (1992) and is illustrated using data from Roxburgh and Wilson (2000a). Results from Wilson and from this study differ (some times substantially), with our approach being more pessimistic about stability and coexistence in plant communities.

Ecological Thinking

During the Renaissance ecological thinking emerged both in printed scientific works and in pictures showing plants against the background of their natural environment. A unique source for the history of plant ecology is the Libri picturati A. 18–30 collection of water-colours kept at the Jagiellonian Library in Cracow (Poland). This collection consists of 13 volumes of plant pictures, and contains about 1,800 images illustrating more than 1,000 taxa mainly from north-western Europe and the Mediterranean region, but also from Asia and America. Some of these pictures match with woodcuts in various works by famous Flemish botanists, mainly Charles de l'Écluse (Carolus Clusius) (1526–1609). Both the illustrations and their short annotations provide a synthetic review of the ecology of the Renaissance period. The paper deals with ecological issues which are found in the collection such as information on the climatic and edaphic requirements of some species, on plants occurring in various habitats and plant communities, plants representing principal growth forms, descriptions of particular adaptations to specific living conditions, for example the halophyte community of sea coasts or the parasitic flowering plants, and phenological observations. These trends can also be seen in printed publications of that time, and this collection mirrors them especially closely.

History Of

Environmental study of the Tögi Ndrawa Cave by means of pollen analysis has been carried out. The interpretation is made based on the occurring pollen types as guide, the resulted pollen spectra, and curves exhibited in the pollen diagram. Combined evidences obtained from the palynological, geological and archaeologi cal studies provide the basis for the interpretation of plant ecology of shore and further the vegetational history of the marine area. In the meantime, plant ecology itself is concerned not only with plant communities but also the interaction among the plants involved, and their environmental factors.

Interpretasi ini berdasarkan hadirnya jenis polen sebagai petunjuk dalam membentuk diagram polen. Hasil studi palinologi, geologi dan arkeologi telah menghasilkan interpretasi dasar mengenai ekologi tumbuhan pantai kemudian sejarah tumbuhan yang pernah tumbuh didaerah laut dangkal. Pada zaman ini, ekologi tumbuhan tidak hanya tergantung komunitas tumbuhan tetapi justru tergantung pada interaksi diantara komunitas tumbuhan dan faktor lingkungannya.
