Abstract Aim Grazing intensity and fire patterns across the Eurasian steppes have changed dramatically over past decades due to collapse of Soviet Union in 1991, Kazakhstan is now a global hotspot. The implications these changes for ecosystem functioning are largely unclear. We aimed understand effects grazing frequency on key engineer, yellow ground squirrel Spermophilus fulvus , very large sc...

cytogenetic approaches are used in systematic studies implying differences between species and variation between populations. in this study, morphology of chromosomes and chromosome number of 210 specimens of 23 rodent species from different localities of iran were investigated. specimens belong to five families comprising dipodidae (allactaga elater (2n=48, fna=92); a. williamsi (2n=48, fna=92...

Myxobacteria, phylogenetically located in the delta division of the Proteobacteria, are well known for characterized social behaviors and large genomes of more than 9 Mb in size. Myxococcus fulvus is a typical species of the genus Myxococcus in the family Myxococcaceae. M. fulvus 124B02, originally isolated from a soil sample collected in Northeast China, is the one and only presently known myx...

Previously we reported the unique Cryptosporidium sp. "c" genotype (e.g., Sbey03c, Sbey05c, Sbld05c, Sltl05c) from three species of Spermophilus ground squirrel (Spermophilus beecheyi, Spermophilus beldingi, Spermophilus lateralis) located throughout California, USA. This follow-up work characterizes the morphology and animal infectivity of this novel genotype as the final step in proposing it ...

Recent populations of the red sunflower seed weevil, Smicronyx fulvus LeConte (Coleoptera: Curculionidae), have been inconsistent or declining, particularly in North Dakota. Consequently, research on weevil biology, including development of resistant germplasm, has been limited. To determine whether cold storage of diapausing larvae could be improved, nonconstant temperature treatments (fluctua...

The substantial body of research on Holarctic ground squirrels amassed over the past century documents considerable variability in morphological, cytogenetic, ecological, and behavioral attributes in the genus Spermophilus F. Cuvier, 1825. Recent molecular phylogenetic studies suggest that the traditionally recognized genera Marmota Blumenbach, 1779 (marmots), Cynomys Rafinesque, 1817 (prairie ...

Biological invasions with known histories are rare, especially in the sea, and empirical studies of the genetic consequences are even rarer. Fifty-five years ago, the state of Hawai'i began a remarkable, if unintentional, 'experiment' with the introduction of three reef fishes, Lutjanus fulvus, Cephalopholis argus and Lutjanus kasmira. All have since expanded from the initial introduction of 22...

The Kresna Gorge attracts significant scientific ornithological interest as it is situated along one of the primary bird migration routes – Via Aristotelis. In 2010, a process reintroducing Griffon Vulture (Gyps fulvus) began in area, which can now be deemed success. However, there are still various anthropogenic factors that have negative impact on population’s resilience. purpose this study t...

Ornithodoros turicata has been collected in Mexico and the United States. In the United States it is found in the states of Arizona, California, Colorado, Florida, Kansas, New Mexico, Oklahoma, Utah, and Texas. It is reported a vector of relapsing fever in Mexico, and in Kansas, New Mexico, Oklahoma, and Texas (Davis, 1942, Am. Assoc. Adv. Sci., 18, 67-76). In June, 1944, 121 Ornithodoros ticks...
