Abstract
The present study provides a detailed ecological and palynological studies on some selected grasses growing naturally in the Deltaic Mediterranean coast of Egypt, namely: Bromus diandrus, Elymus farctus, Aegilops bicornis, Stipagrostis lanata and Hordeum murinum, and it aims at the following objectives: 1- Study the floristic features including record of plant species, life-span, life-form spectrum and chorological affinities of the plant species associated with the selected grasses in the study area to detect the taxonomic and phytogeographical significance of its floristic components. 2-Quantitative analysis of vegetation structure of plant communities associated with selected grasses by using multivariate analysis (classification and ordination).3- Analysis of variations in edaphic factors to determine the soil factors controlling the abundance and distribution of the recognized plant communities associated with the chosen grasses in the study area. 4- Documentation morphology of the Egyptian pollen grain flora.5- Identification the fodder plants used in the past by animals. In conclusion, the present study suggests that the chosen five grasses: Bromus diandrus, Elymus farctus, Aegilops bicornis, Stipagrostis lanata and Hordeum murinum as palatable fodder for animals. Through the fossil pollen analysis of dung animals of the profile, it was found that not only family Poaceae can be used as fodder but also many members of other families in the study area can be used fodder, such as families Fabaceae (Leguminosae), Asteraceae (Aster type), Asteraceae (Fenestrate type), Asteraceae (Carthamus glaucus), Asteraceae (Pluchea dioscoridis), Tamariaceae, Polygonaceae, Brassicaceae, Poaceae (Gramineae type) and Convolvulaceae).
