Studies on the bryoflora of some wadis in Saint Catherine protected area
Mai Ahmed Mohamed Taha;
Abstract
The purpose of this study was to investigate herbarium moss samples collected from 5 wadis in Saint Catherine protected area as well as to collect new ones and to study distribution, occurrence, purity, association and reproductive structures of the species. To achieve this aim, 191 moss samples (314 specimens) have been studied.
This work includes:
Diagnostic descriptions of orders, families, genera and species recorded in the study area.
Identification keys for orders, genera and species of each genus in the study area.
Photographs of all organs and structures of all species.
States of major leaf characters and their bearings on relations of the studied flora with floras of other regions.
Study of distribution, occurrence, purity, association and reproductive structures of species recorded in the study area.
Comparison between moss species of the study area with those of other territories in Egypt, neighboring countries and the world.
The investigation of bryoflora in the study area revealed the following:
The studied samples included 43 moss species in 17 genera, six families and six orders.
The largest genus was Bryum; represented by 11 species.
Anoectangium is not represented in any Egyptain territory being a new record to the country.
Half the number of species of Gymnostomum, Gyroweisia, Syntrichia and Ptychostomum recorded in Egypt are represented in the study area.
Six of the studied species; namely, Eucladium verticillatum, Didymodon tophaceus, D. vinealis, Bryum radiculosum, B. turbinatum and Ptychostomum archangelicum were widely distributed (occur in 4 out of the 5 studied wadis). While 17 species were restricted to one wadi each.
The most frequent species were Eucladium verticillatum, Didymodon tophaceus, and Bryum radiculosum represented by 55, 26 and 23 specimens respectively.
The number of species recoded in spring was 36, in summer 16 and in winter 15 species. So, variation of species was highest in spring (April).
