The continuous increasing accumulation of carbon dioxide (CO2) and other greenhouse gases (GHGs) in the atmosphere is commonly known as the most significant cause of global warming and, therefore, the alteration of the world's climate. This has promoted urban planting projects for many countries. Therefore, it is imperative to select high carbon se...

North Sinai is a location of ecological significance because of its physiographic changes and environmental gradients. The purpose of this study was to elucidate the recent alterations in the floristic structure and composition of North Sinai brought about by humanity and the current drought revealing new records with a comprehensive investigation...

The present study seeks to assess waterbird diversity and water and sediment quality at Ashtoum El-Gamil protected area, Egypt, after a dredging project. The Lake Manzala dredging project started in 2017 and aims to improve the water quality in the lake mainly by enhancing water exchange between the lake and the sea. Waterbird diversity was assesse...

Climate change is a critical worldwide concern that affects every aspect of existence and all living beings. The study of climate change's impact on invasive species has piqued the interest of researchers worldwide due to the possible ramifications for biodiversity and vulnerable species protection. Phragmites australis (Cav.) Trin. Ex Steud. (Poac...

Chiliadenus montanus (Vhal.) Brullo is a vulnerable medicinal plant species growing in the Saint Katherine area, South Sinai, Egypt. It is subjected to overgrazing and collection by Bedouins for its high medicinal value in treating different diseases due to its effective bioactivity. Contributing in designing a conservation plan, this study aims to...

The Mediterranean coastal land of Egypt has a rich wild vegetal heritage, including a distinctive diversity of medicinal plants. Wild Mesembryanthemum species can adapted to the environmental fluctuations through some physiological and biochemical processes. No sufficient cytological and karyological information on Mesembryanthemum species is avail...

One of the most important issues nowadays is memory disorders. The exact circadian modulation of learning and memory is still under investigation. The present study was carried out to evaluate the probable enhancing and neuroprotective effects of the Egyptian Moringa peregrina; administered at two different Zeitgeber times (ZT), on learning and mem...

This book addresses the ecology, age dating, and demography of Moringa peregrina, as an important but threatened medicinal plant species growing in Sinai, It is one of the most important trees in Bedouin’s life in deserts of Egypt and Middle East. natural populations of M. peregrina suffer multiple stresses lead to decrease in their sizes and numbe...

The karyotypic characters, mitotic metaphase chromosomes and karyograms of ten populations of three species of Plantago L. (P. lagopus L., P. major L. and P. squarrosa Murr.) in Egypt were determined and compared with each other. Analysis of somatic metaphase showed that the chromosome numbers were 2n = 12. Although all the species had the same chr...

St. Katherine Protectorate is considered as a center of endemism where the area haswetter climate than most of Sinai and characterized by having large outcrops of smoothfacedrocks which support rare and endemic plant species. Hypericum sinaicum is one ofthe rarest species growing in St. Katherine Protectorate and is subjected to a number ofthreats,...

The present study aimed to assess the impact of fencing of Acacia tress inside enclosures on grow th and productivity against unfenced trees, and selecting an appropriate number of Acacia populations in the area that would represent the most important variations in the physiographic structure in order to conserve the current populations. Thirteen e...

The vegetation and wild life in Saint Catherine area is subjected to great disturbance through the unmanaged human activities. In the present study we had used seed ecology in order to contribute in designing a sound long term conservation plan for the two threatened endemic studied medicinal species; Plantagosinaica, and two other Plantago species...

There are three species of the genus Mesembryanthemum recorded in Egyptian flora (Mesembryanthemum crystallinum L., Mesembryanthemum nodiflorum L. and Mesembryanthemum forsskaolii Hochst. ex Bioss.). Various genetic markers (SDS-PAGE, RAPD and ISSR) have been applied to evaluate the genetic variability and structure within and between twelve popula...

Background and aims – It is a key conservation aim to maintain genetic diversity within populations of rare and threatened species. The flora of the Sinai Peninsula is unique and, therefore, of strong interest. However, in only few studies genetic structure and variation within and among populations of Sinai plants have been analysed. In the study...

There are increasing threats facing the rare plants including the endemic populations. Also the potential development of the earth's vast desert areas for agriculture and other human-needs demands an awareness of the ecological characteristics and requirements of desert vegetation. Saint Catherine area has a unique location and environment. The veg...

The contribution of soil seed bank of a desert endemic plant species in maintaining genetic diversity has been addressed in this paper through investigating the differences in genetic diversity and structure (using AFLP markers) between plants grown from soil seed bank and standing crop plants within and among five populations of H. sinaicum growin...

Several threats affect Moringa peregrina populations and lead to high mortality, low recruitment, and poor survival rates. To conserve M. peregrina, understanding the populations’ dynamics is fundamental. Four Wadis in Southern Sinai, Egypt, representing the known local geographic distribution were surveyed and selected for the study. Age of cross-...

Several threats affect the existence of Moringa trees in Southern Sinai. The trees are subjected to extreme drought in its hyper-arid environment. Unmanaged utilization of this valuable tree is very short-sighted and leads to high mortality, low recruitment, and poor survival of its seedlings. The present study aims to find the conditions for optim...

Moringa peregrina which is one of the most valuable and economically important medicinal species in the Egyptian desert has become one of the most endangered trees due to unmanaged grazing and over-collection. The present study aims to provide ecological assessment of the species and to investigate whether progeny from the remnant fragmented popula...

The main aim of this study was to elucidate the complex inter-relations between elevation, edaphic features, topography, prevailing wind speed and vegetation distribution on Saint Catherine mountains. Vegetation sampling was carried out at 37 stands distributed on five main mountains, and the cover percent of each species was recorded in five plots...

Acacia tortilis subsp. raddiana (Fabaceae) plays an important role in the life of desert animals and is a major source of livestock feed and firewood for the native Bedouin people in Southern Sinai, Egypt. High mortality and low juvenile recruitment has been reported in recent years leading to decline in population size and number of this species....

Understanding the diversity level of seed bank is important for designing conservation and restoration programs especially in arid ecosystems. A diverse of diversity indices has been used in evaluating seed communities regardless of its suitability to measure the ecological quality of the targeted biological community. The current study aims to eva...
