Sargassum fluitans and natans, types of brown algae wash up on Galveston Island, Texas each year from May to August. Sargassum smells bad, hurts tourism and impairs sea turtle hatchings. Coastal managers are confronted with the difficult choice of cleaning Sargassum off the beach front or leaving it alone. The current beach management practice is to rake the algae with mechanical tractors and d...

BACKGROUND AND AIMS Fifty-two populations were sampled in order to establish the taxonomic delimitation and relationships of eight taxa belonging to the A. majus L. and A. siculum Miller groups. METHODS Data on 13 allozyme loci were recorded after extraction of fresh leaves and electrophoresis on horizontal 10% starch gels. KEY RESULTS Genetic distances between conspecific populations are l...

Corresponding Author: Saidu, A.N __________________________________________________________________________________________ Abstract The phytochemical screening and hypoglycemic effect of methanolic extract of Gongronema latifolium leaf in alloxan induced diabetic rats were investigated. The methanolic extract of Gongr...

Rural dwellers in Nigeria often resort to herbal remedy and dietary control in the treatment of diabetes mellitus (DM). This work was undertaken to provide the rationale for the use of the leaves of Gogronema latifolium as a traditional antidiabetic agent. Methanol extract (ME) of the leaves of G. latifolium was prepared by soxhlet extraction while the aqueous extract (AE) was prepared by cold ...

In recent years there have been massive inundations of pelagic Sargassum, known as golden tides, on the beaches of the Caribbean, Gulf of Mexico, and West Africa, causing considerable damage to the local economy and environment. Commercial exploration of this biomass for food, fuel, and pharmaceutical products could fund clean-up and offset the economic impact of these golden tides. This paper ...

 Piptatherum ferganense is recorded as a new grass species for the flora of Iran collected from Ghorkhod Protected Area and Aladagh Mountains in North Khorassan province. The core distribution range of the species is Eastern Irano-Turanian with a disjunction in northeastern Iran. The morphological characters of P. ferganense are illustrated and compared with the closely related P. latifolium. I...

Species distribution modeling was used to determine factors among the large predictor candidate data set that affect the distribution of Muscari latifolium, an endemic bulbous plant species of Turkey, to quantify the relative importance of each factor and make a potential spatial distribution map of M. latifolium. Models were built using the Boosted Regression Trees method based on 35 presence ...

The present paper highlights the effect of water stress (drought) on the proximate composition of the leaves of Ocimum gratissimum and Gongronema latifolium. Cultivated O. gratissimum and G. latifolium plants grown in plastic planting buckets were subjected to mild water stress by irrigating each planning bucket with 500 ml of water once in a week. In the control treatment, each bucket was supp...

Competition and fouling defence are important traits that may facilitate invasions by non-indigenous species. The 'novel weapons hypothesis' (NWH) predicts that the invasive success of exotic species is closely linked to the possession of chemical defence compounds that the recipient community in the new range is not adapted to. In order to assess whether chemical defence traits contribute to i...

The invasiveness of algal species can be facilitated by chemo-ecological traits that allow the establishment of invasive species in a highly competitive environment. Anti-bacterial, anti-quorum sensing, anti-diatom and anti-larval properties of the invasive brown macroalga Sargassum muticum and three native Sargassum species from Oman waters were compared in laboratory and field experiments to ...
