the aim of this research was to study the relationships between presence of plant species and environmental factors in garizat rangelands of yazd province and providing their predictive habitat models. after delimitation of the study area, sampling was performed using randomized-systematic method. accordingly, vegetation data including presence and cover percentage were determined in each quadr...

Bamboos are prominent components of many tropical ecosystems, yet little is known about the physiological mechanisms utilized by these gigantic forest grasses. Here, we present data on the water transport properties of Chusquea ramosissima and Merostachys claussenii, monocarpic bamboo grasses native to the subtropical Atlantic forests of Argentina. C. ramosissima and M. claussenii differed in t...

Riparian plants in arid areas are subject to frequent hydrological fluctuations induced through natural flow variation and water use by humans. Although many studies have focused on the success of Tamarix ramosissima Ledeb. in its invaded ranges, its major competitor in its home range, Populus euphratica Oliv., historically has dominated riparian forests where both species occur naturally. Thus...

Hydrologic alterations of river systems in western North America over the past century have increased soil salinity, contributing to the establishment and spread of an introduced halophytic species, Tamarix ramosissima (Ledeb.). The physiological responses of Tamarix ramosissima to salinity stress are incompletely known. To assess the salinity tolerance of this species, we measured several whol...

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...

Crotolaria ramosissima is a weed plant belonging to the family Leguminoseae. It is a much branched sticky woody herb. The flowers are yellow tinged with purple. It is distributed in some places of Tamilnadu and coastal areas of Andrha Pradesh. The plant contains waxes, and, when flowering, a yellow exudate appears in the inflorescences. Recently, we published the corrected structure of crotaram...

—Predictive models of aboveground biomass of nonnative Tamarix ramosissima of various sizes were developed using destructive sampling techniques on 50 individuals and four 100-m2 plots. Each sample was measured for average height (m) of stems and canopy area (m2) prior to cutting, drying, and weighing. Five competing regression models (P < 0.05) were developed to estimate aboveground biomass of...

Populus fremontii (Fremont cottonwood) was once a dominant species in desert riparian forests but has been increasingly replaced by the exotic invasive Tamarix ramosissima (saltcedar). Interspecific competition, reduced flooding frequency, and increased salinity have been implicated in the widespread decline of P. fremontii. To elucidate some of the multiple and interacting mechanisms of this d...

Hydrothermal carbonization (HTC) is a novel thermochemical conversion process to convert lignocellulosic biomass into value-added products. In this work, two different biomass materials: corn stalk and Tamarix ramosissima were used as feedstock. HTC processes were performed at the temperature of 250 °C for 4 h, using a batch reactor system. Chemical and structural characterization of the solid ...

Transfer of herbicide resistance genes between crops and weeds is relatively well documented; however, far less information exists for weed-to-weed interactions. The hybridization between the weedy diploids Conyza canadensis (2n = 18) and C. ramosissima (2n = 18) was investigated by monitoring transmission of the allele conferring resistance to N-phosphonomethyl glycine (glyphosate). In a multi...
