We studied the relationship between the use of three detoxification pathways and urine pH and the tolerance of desert woodrats from two populations to a mixture of naturally occurring plant secondary metabolites (mostly phenolics) in resin from creosote bush (Larrea tridentata). The two populations of desert woodrats came from the Mojave desert (Mojave woodrats), where woodrats consume creosote...
This study was conducted to understand the morphological variation of four populations of Schizothorax pelzami from Iranian inland waters. For this purpose, a total of 81 specimens were collected from the Bidvaz, Cheshmeh-Ali, Kalat and Aal rivers. After anesthesia, all specimens were fixed into buffered formalin and transferred to the laboratory. Then, the left sides of all individuals were ph...
a total of 2519 blood samples were collected from five distinct populations of larestan, in fars province, in iran (lar, gerash, khour, latifi and berake) were examined for abo and rh blood groups. the gene frequencies obtained from these samples were compared with the hitherto reported corresponding data from other populations of fars province to determine the genetic structure of the larestan...
How temperate forests will respond to climate change is uncertain; projections range from severe decline to increased growth. We conducted field tests of sessile oak (Quercus petraea), a widespread keystone European forest tree species, including more than 150 000 trees sourced from 116 geographically diverse populations. The tests were planted on 23 field sites in six European countries, in or...
The aim of the present study was the genetic analysis of the Dniester population of sterlet Acipenser ruthenus and comparison of it to five other sterlet populations, in order to develop a population recovery plan. The genetic analysis of six sterlet populations from Eurasian rivers (Dniester, Dnieper, Danube, Volga, Kama and Ob) was carried out using microsatellite DNA markers. The genetic var...
to finding out the genetic structure of iranian native horses, as animal blood samples were obtained from diverse areas of iran, in addition, 114 sequences of equine d-loop region were obtained from genbank. total dna of the samples were extracted through salting out procedure and utilized as template for amplification and sequencing of the d-loop region of mtdna. sequence analysis of the 247-b...
To predict the response of plant pathogens to climate warming, data are needed on current thermal adaptation, the pathogen's evolutionary potential, and the link between them. We conducted a common garden experiment using isolates of the fungal pathogen Rhynchosporium commune from nine barley populations representing climatically diverse locations. Clonal replicates of 126 genetically distinct ...
ABSTRACT The aims of this study were, first, to compare the genetic and virulence diversity between populations of the rust fungus Melampsora larici-populina on wild and cultivated poplar stands and, second, to investigate the influence of the presence of the alternate host of the pathogen, larch, on which its sexual reproduction occurs, on these diversities. Nine French M. larici-populina popu...
Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6. Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...
study of phenotypic diversity among populations can help better understanding of diversification of species within ecosystems and intraspecific diversification in fishes. a geometric morphometric study was carried out using the elliptic fourier analysis to demonstrate the effect of habitat type on morphological features of shemaya ( alburnus chalcoides ) populations. populations were sampled fr...
