BACKGROUND Eosinophilia occurs in a wide variety of situations such as parasitic infections, allergic disorders, and malignancies. Most cases of eosinophilia of parasitic origin, especially those with a tissue migration life cycles consists of human infections by helminth parasites. The aim of present study was to determine the parasitic causes of eosinophilia in patients in a major endemic are...

Remote sensing offers a cost efficient means for identifying and monitoring wetlands over a large area and at different moments in time. In this study, we aim at providing ecologically relevant information on characteristics of temporary and permanent isolated open water wetlands, obtained by standard techniques and relatively cheap imagery. The number, surface area, nearest distance, and dynam...

population of vimba vimba persa was investigated using microsatellite markers originated from two regions along the iranian coastline of southern caspian sea (anzali lagoon and havigh river in gilan province). totally 153 alleles were identified. the highest number of alleles per ca3 loci was 17 and the lowest 3 in z8145 loci with means of 7.6. observed and expected heterozygosity averages were...

Road mortality has the potential to alter the structure of turtle populations because turtle populations are highly sensitive to additive sources of adult mortality. To address the issue, we captured painted turtles ( Chrysemys picta; n = 174) and snapping turtles ( Chelydra serpentina; n = 56) in 18 wetlands surrounded by low road density (≤1.5 km roads/km of landscape) and 17 wetlands surroun...

Wetlands provide many ecosystem services to society, most notably the provision of habitat for important plants and animals, the improvement of water quality, and the sequestration of carbon. Nitrogen and phosphorus budgets, vegetation structure and function, and carbon fluxes and accumulation are described for a pair of 1-ha created riverine wetlands in central Ohio USA over 20 years (1994–201...

 Population genetic structure of Vimba vimba persa was investigated using microsatellite markers from 40 regions along the Iranian coastline of the Southern Caspian Sea (Anzali lagoon and Havigh River in Gilan province, BabolRoud River in Mazandaran province and GorganRoud River in Golestan province). Genomic DNA from 121 specimens was extracted from fin tissue by the Phenol-Chlorophorm method ...

Natural wetlands, occupying 3.8% of China's land and providing 54.9% of ecosystem services, are unevenly distributed among eight wetland regions. Natural wetlands in China suffered great loss and degradation (e.g., 23.0% freshwater swamps, 51.2% costal wetlands) because of the wetland reclamation during China's long history of civilization, and the population pressure and the misguided policies...

Concern over historic wetlands loss led to a national goal of no net loss (NNL) of wetlands acres and their environmental services. In support of the NNL goal, the US Army Corps of Engineers (Corps), under authority granted by Section 404 of the Clean Water Act, reviews permits to discharge fill material into wetlands. A permit review process called sequencing requires a permit applicant (permi...
