Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, Kordestan, Harati, Enaj and Lordegan), T. repense, T, fragverm, T. prateme and T, alexandrin...

the genus aegilops is one of the wheat relatives which comprise the main part of its gene pool.the identification of the aegilops species is difficult due to their vast morphological similarities and geneflow among different species of aegilops and cultivated wheat. some morphological characters are used todistinguish different species in aegilops. in this study, we evaluate all these character...

Many scuticociliates are facultative parasites of aquatic organisms and are among the most problematic ciliate taxa regarding their systematic relationships. The main reason is that most species, especially taxa in the order Thigmotrichida have similar morphology and have not been studied yet using molecular methods. In the present work, two scuticociliate genera, represented by two rare parasi...

Three species of the genus Xylaria (Xylariaceae) are presented based on collections from Guilan Province, Iran. Both morphological and molecular characteristics were used in order to identify these species. Xylaria longissima sp. nov. is described and illustrated as a new Xylaria species and X. cf. striata and X. xylarioides are reported as new records from Iranian mycobiota. Xylaria longissima...

BACKGROUND T1 mapping is widely used today in CMR, however, it underestimates true T1 values and its measurement error is influenced by several acquisition parameters. The purpose of this study was the extraction of accurate T1 data through the utilization of comprehensive, parallel Simulations for QUAntifying RElaxation Magnetic Resonance constants (SQUAREMR) of the MOLLI pulse sequence on a l...

Flocks participating in sire referencing schemes can achieve greater genetic gains than those achievable by within-flock selection. However, requirements for joining these schemes can be prohibitive to some producers. The objectives of this study were to determine whether less restrictive schemes or schemes of shorter duration could achieve rates of gain and reduce inbreeding as efficiently as ...

While holding great development opportunities to be seized, Africa has been identified as particularly vulnerable to climate changes, and the ZRB is no exception to that. With increasing demands to the Zambezi system in terms or water and energy, and rising challenges in the form of less runoff due to climate change, it is paramount to plan ahead. In particular, it must be understood how major ...

The Agricultural Policy Environmental eXtender (APEX) model is capable of estimating edge-of-field water, nutrient, and sediment transport and is used to assess the environmental impacts of management practices. The current practice is to fully calibrate the model for each site simulation, a task that requires resources and data not always available. The objective of this study was to compare m...

Using the most recent atmospheric neutrino data, as well as short-baseline, longbaseline and tritium β-decay data we show that the joint interpretation of the LSND, solar and atmospheric neutrino anomalies in (3+1) sterile neutrino schemes is severely disfavored, in contrast to the theoretically favored (2+2) schemes.
