We captured Nelson's, Saltmarsh and Seaside Sparrows (Ammodramus nelsoni, A. caudacutus and A. maritimus) at three salt marsh sites near Wrightsville Beach, North Carolina during five non-breeding seasons (September through April, 2006-2011). We analyzed breast feather samples from all of these seasons and blood and first primary feather (P1) samples from three seasons (2008-2011) for mercury (...

Members of the Lotus genus are important as agricultural forage sources under marginal environmental conditions given their high nutritional value and tolerance of various abiotic stresses. However, their dry matter production is drastically reduced in cooler seasons, while their response to such conditions is not well studied. This paper analyzes cold acclimation of the genus by studying Lotus...

BACKGROUND AND PURPOSE Daily variation in outdoor concentrations of inhalable particles (PM(10) <10 microm in diameter) has been associated with fatal and nonfatal stroke. Toxicological and epidemiological studies suggest that smaller, combustion-related particles are especially harmful. We therefore evaluated the effects of several particle measures including, for the first time to our knowled...

Temperate climates are defined by distinct temperature seasonality with large and often unpredictable weather during any of the four seasons. To thrive in such climates, trees have to withstand a cold winter and the stochastic occurrence of freeze events during any time of the year. The physiological mechanisms trees adopt to escape, avoid, and tolerate freezing temperatures include a cold accl...

Global warming can cause deep and extensive changes in the Earth’s climate time place of climatic phenomena. The present trend analysis study assesses cold stress using thermo-hygrometric index (THI) two seasons autumn winter outdoor environments Iran. data related to average variables daily air temperature relative humidity from 60 synoptic meteorological stations for a statistical period 30 y...

BACKGROUND Climate change and global warming have significant effects on human health. This systematic review presents the effects of the climate changes on pregnancy outcomes. MATERIALS AND METHODS The search process was conducted in electronic databases including ISI Web of Knowledge, PubMed, Scopus, and Google Scholar using key words of "environmental temperature" "pregnancy" "low birth we...

introduction climate has always been one the main factors of designing urban spaces in iran since past centuries. by analyzing urban spaces it can be concluded that different cities have different urban spaces due to climate differences. one of the main reasons of the differences in the type and orientation of urban spaces is the climate as one of the key factors in designing these areas. regar...

this study was conducted to determine grain yield stability of rainfed promising barley genotypes across six rainfed research stations (maragheh, sararood, uromieh, qamloo, zanjan and ardabil) under cold and semi-cold conditions during three cropping seasons (2006-2009) in iran. the studied genotypes were 10 promising barley lines along with two checks (one local and one newly released variety,...

Constructed treatment wetlands have been found to remove fecal coliform (FC) through a variety of mechanisms. This research evaluated the removal of FC in both warm and cold seasons from surface flow treatment wetlands in Bible Hill, Nova Scotia. Two wetlands (100 m), of differing depths were monitored over a 17 month period. The wetlands were loaded with dairy wastewater (average inlet FC conc...
