In this paper, the new taxa Lepidium ferganense (Brassicaceae) was recorded for the flora of Iran for the first time. This taxon belongs to Irano-Turanian region. It was compared with the closest taxa in the present study. In addition, a morphological description, several Illustrations, and a distribution map were presented.

in this study, a taxonomic status of the genus roemeria in iran is reviewed. the study of morphological characters of collected and herbarium specimens led to the introducing of two new taxa, namely, r. hybrida subsp. maculata and r. refracta var. alba. in addition, five synonymies are made as following: r. refracta var. albomarginata and r. refracta subsp. occidentalis as synonymies of r. refr...

Abstract Less variable than life history parameters (LHPs), it is ratios (LHRs) that define how taxa allocate energy between growth, maintenance and reproduction, respond to fishing pressure. Limited by small samples, data quality, a focus on LHP estimation, previous meta-analyses have failed settle debate about the extent which LHRs are relatively invariant across all or characteristic of spec...

A common and important task in microarray experiments is the identification of genes whose expression values differ substantially between groups or conditions. Finding such differentially expressed genes requires methods that can deal with multiple testing problems in which thousands or even tens of thousands of hypotheses are tested simultaneously. Usually, a statistic appropriate for testing ...

Islands represent interesting biogeographic features often defined by unique and dynamic geological biological components. Such systems serve as examples of the basic fundamental units biogeographical analyses: areas endemism. The island Jamaica is recognized possessing a biota with large number herpetofauna species persisting only within island. Further, exhibits geologic history characterized...
