Floristic study is one of the most efficient methods of gaining knowledge about biological capacities, as well as management and conservation of plant genetic resources in ecological systems. Zanjan county town is located in a mountainous region with an area of 6763 km2 and the average altitude of 1663 m.a.s.l. Its favorable vegetation diversity is the result of suitable ecological conditions, ...
zarivar lake is the only natural water area and the ponds in the kurdistan province which is located 2 kilometers far from the northwest of marivan city and at an altitude of 1285 meters above sea level. the mean annual rainfall is 997.6 mm and the mean annual temperature is 13°c. this study is carried out to survey the biodiversity, identification and introduce plant species around the lake an...
Ticks of the genus Rhipicephalus (Acari: Ixodidae) in Senegal were reviewed. The data presented originate from a tick collection maintained at IRD’s Laboratory Medical Entomology since 1967 and continuously enriched with samples obtained different vertebrate hosts captured during various projects conducted 1987 to 2007. Fifteen species collected characterized, resulting 1127 referenced collecti...
Recognizing of plants present in a region is considered as a baseline study for ecological research, management and conservation of plants. The purpose of this study was to collect and identify the plants of Azizak and Paein Ahmad kola Wetlands of Babolsar in Mazandaran province. After specifying the boundaries of the study areas on the map and conducting field visits, the plants were collecte...
A forest area in Deh-Kohneh, the northwest of Fars Province, Iran was studied from a floristic and ecological point of view. The species were classified according to their growth habit. Raunkiaer’s life - forms systemwere used to characterize the flora of the study area. The location has a surface area of 466 ha by minimum altitude at 2100m and maximum at 2554m, between 30 ° 21΄ 32˝ to 30° 23΄ ...
The family Gymnophthalmidae contains nearly 235 species with a distribution range from southern Mexico to central Argentina as well as in the Antilles. Among gymnophthalmids, the genus Colobosaura is a member of the tribe Iphisini, and currently is considered monotypic (C. modesta). The diversity of the tribe was studied recently, with the erection of several new genera. In this work genetic an...
Background and objectives: Riparian vegetation along the river is one of the most sustainable aboveground covers that is a good source of food for livestock. Considering the degraded riparian areas, studies on soil seed bank is important and, necessary for restoration goals. Methodology: The present study was conducted to investigate the soil seed bank in the riparian region of the Gamasiab ri...
We have performed an extensive study on the responses to salt stress in four related Limonium halophytes with different geographic distribution patterns, during seed germination and early vegetative growth. The aims of the work were twofold: to establish the basis for the different chorology of these species, and to identify relevant mechanisms of salt tolerance dependent on the control of ion ...
For a monograph based on a polythetic concept, several thousands of herbarium specimens, and several hundreds of freshly collected and cultured specimens of Daldinia and allied Xylariaceae, originating from around the world, were studied for morphological traits, including by SEM, and chemically by HPLC profiles using UVvisible and mass spectrometric detection. Emphasis was given to tropical ma...
