Introduction & Objective: During the most dental procedures, contamination of devices with blood, saliva and other body fluids, which is the most important factor for transmission of infectious diseases, is inevitable. Therefore principles of infection control should be carefully considered in the dentistry. The purpose of this study was the evaluation of bacterial contamination of active radio...
Ocean warming is causing declines of coral reefs globally, raising critical questions about the potential for corals to adapt. In central equatorial Pacific, persisting through recurrent El Niño heatwaves hold important clues. Using an 18-year record cover spanning three major bleaching events, we show that impact thermal stress on mortality within Phoenix Islands Protected Area (PIPA) has less...
The Mirabad protected area (S. Azarbaijan, Iran) has a variety of ecological nurseries due to elevation of the sea, physiographic factors, micro-climates and soil types, and has high vegetation diversity. Mirabad protected area in the Piranshahr-Sardasht axis is between the latitudes of 36° 23' and 36° 31' north, and the lengths 45° 15' and 45° 25', with an area of 11435 ha, in the elevation ...
Spatiotemporal and physiochemical influences on the abundances diversity of ichthyoplankton were assessed in Thermaikos Gulf edge habitats surrounding Pieria (Northern Greece) artificial reef complex. The collection data was performed marine protected area near offshore Kitros. Sampling trips occurred each season spring, summer, autumn year from 2015–2017. This complex lies at a distance 11.5 k...
This study examined the spatial and temporal rainfall variability from the 1940s to 2007 in the south west coastal region of Bangladesh. Time series statistical tests were applied to examine the spatial and temporal trends in three time segments (1948–1970, 1971–1990 and 1991–2007) and four seasons (Pre-monsoon; Monsoon; Post-Monsoon and Winter), during the period 1948–2007. Eight weather stati...
The wetlands in the Prairie Pothole Region and in the Great Plains are notorious for their sensitivity to weather variability. These wetlands have been the focus of considerable attention because of their ecological importance and because of the expected impact of climate change. Few models in the literature, however, take into account spatial variation in the importance of wetland drivers. Thi...
Introduction: Rangelands constitute almost 52 percent of the country area computed as 164 million ha. The extent of rangelands has been estimated 84 million ha in Iran and they have been classified as good, moderate to poor and poor to very poor ones ranged as almost 10, 42 and 48 percent, respectively. One of the fundamental problems concerning land uses of rangelands is that Rangeland are not...
Shrimp trawling fishery in the Gulf of California captures a wide variety of non-target species of fish, crustaceans, and mollusks that are relatively unknown. The Pacific flagfin mojarra Eucinostomus currani is a frequently found species in these catches, nevertheless, nothing is currently known about its population dynamics. To contribute to the knowledge on this fish species, we studied the ...
investigating species diversity and richness is essential for defining conservation priorities. in addition, determining landscape parameters influencing species diversity and richness is important for selecting and designing parks and protected areas. kohgiluyeh & boyer ahmad province is a mountainous region, comprises hills, mounds, forests and plains. this vast province has high species dive...
