Aim: To evaluate the analgesic activity of aqueous extract of S. hispida on thermal and chemical method induced pain in mice. Materials and methods: 48 Adult albino mice (Swiss strain) weighing 25-30 gm were selected. 24 animals were allocated to each experimental model, in each model there were 4 groups. The control group received vehicle (10 ml /kg, p.o), standard group aspirin (300 mg /kg, p...

Populus deltoides subsp. wislizinii (Salicaceae), a cottonwood native to the Middle Rio Grande of New Mexico, must potentially compete against exotic Tamarix ramosissima (Tamaricaceae) during establishment after flooding. We investigated competitive interactions between seedlings of Tamarix and Populus in two substrates representing field textures and declining (i.e., draw-down) or stagnant wat...

Tamarix is one kind of shrub which is widespread species in sand and saline land in arid and semi-arid regions. Tamarix has been paid more attentions for its unique physiological and ecological features, and important socioeconomic effects. In order to study the biomass and growth status of Tamarix, we need to measure the morphological parameters (e.g. height, perimeter of canopy). However, the...

We examined the impact climate change (CC) will have on the availability of climatically suitable habitat for three native and one exotic riparian species. Due to its increasing prevalence in arid regions throughout the western US, we predicted that an exotic species, Tamarix, would have the greatest increase in suitable habitat relative to native counterparts under CC. We used an ecological ni...

The objective of this study was to evaluate the antibacterial activity of various extracts of whole plant of Borreria hispida (Linn). The extract was prepared from the whole plant of Borreria hispida by hot continuous percolation method in Soxhlet apparatus with various solvents (Pet. Ether, ethyl acetate, Methanol). All the extracts of Borreria hispida were tested for antibacterial efficacy ag...

Ringed seals (Pusa hispida) are broadly distributed in seasonally ice covered seas, and their survival and reproductive success is intricately linked to sea ice and snow. Climatic warming is diminishing Arctic snow and sea ice and threatens to endanger ringed seals in the foreseeable future. We investigated the population structure and connectedness within and among three subspecies: Arctic (P....

Tamarix ramosissima has bi-seasonal flowering and fruit-setting characteristics. This study compared the morphology and germination characteristics of seeds from Tamarix ramosissima plants during the spring flowering period and the summer flowering period. The results are as follows: there is no significant difference in morphology, such as size and thousand-seed weight, between seeds from diff...
