Background & Aim:Cognitive impairment is one of the age-related mental problems and a typical indicator of neurodegeneration. Eragrostis tremula Hochst. ex Steud. is a commonly used medicinal plant in Nigeria for memory enhancement. This study, therefore, aimed at evaluating the memory-enhancing potential of aqueous ethanolic extract of E. tremula in ...

Eragrostis is a large genus in subfamily Chloridoideae of Poaceae. Recent phylogenetic analyses have suggested that the genus may not be monophyletic, that some of its segregate genera may be better placed within Eragrostis, and that current infrageneric classifications may not represent monophyletic groups. We have used molecular sequence data from the plastid locus rps16 and the nuclear gene ...

Abstract Background Eragrostis tremula Hochst. ex Steud. (Poaceae) is used in ethno-medicine as a memory enhancer. Studies have shown that the whole plant possesses enhancing potentials and could be beneficial management of amnesia cognitive deficit. Aim This study was aimed at investigating actions E. extract on diazepam-induced mice. Acute toxicity profiling done stated by Organization for Ec...

The Cameroonian flora has a very high biodiversity that remains largely unexplored. It contains many grasses can be used for sports lawns, but are currently underutilized. In order to contribute the improvement of quality nine local grass taxa from agro-ecological zone with bimodal rainfall in Cameroon were evaluated their potential sporting use natural lawns. method Study and Control Group Var...

Stomatal, CO2 exchange parameters and several leaf and growth traits were recorded in a fi ve-year-old hybrid aspen clone trial. The fi eld trial consisted of four aspen hybrid clones (Populus tremula L. × P. tremuloides Michx.) and one local Populus tremula seedling source. The mean estimated height of hybrid aspen clones was 1.6 times higher than for P. tremula. Similarly, basal diameter was ...

Chaetaglaea tremula (Harvey) occurs through the Gulf States, from southern Florida, west to eastern Texas. Coastal populations, previously referred to Chaetaglaea tremula occurring from the Carolinas, at least as far north as Massachusetts and shoreline dunes in southwestern Ontario are recognized as distinct and described here as Chaetaglaea rhonda. Adults and genitalia are illustrated for Cha...

Fast-growing trees such as Salix viminalis L. and Populus tremula L. are well suited to phytoremediate heavy metal contaminated soils. However, information on tree performance, particularly leaf function, under conditions of heavy metal contamination is scarce. We used yearly coppiced saplings of S. viminalis and P. tremula growing in model ecosytems to test four hypotheses: (1) heavy metal con...

I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high frequency derived mutations at silent sites, relative to neutral e...

Litter decomposition is a fundamental ecosystem process in which breakdown and decay of plant detritus releases carbon and nutrients. Invasive exotic plants may produce litter that differs from native plant litter in quality and quantity. Such differences may impact litter decomposition and soil respiration in ways that depend on whether exotic and native plant litters decompose in mixtures. Ho...
