Droughts are projected to occur more frequently with future climate change of rising temperature and low precipitation. However, its impact on regional and global vegetation production is not well understood, which in turn contributes to uncertainties to model carbon sequestration under drought scenarios. Using long-term continuous eddy covariance measurements (168 site-year), we present an ana...

The objective of this study was to focus the light on the events of angiogenesis during spring and summer times. For this purpose, testes of ten rams were collected from Baghdad in spring and summer seasons in 2017.Samples were histologically processed and prepared for light microscopy. Hematoxylin and eosin stain was used for staining. The results revealed that the process of angiogenesis was ...

Warm European summer temperatures are often preceded by low soil moisture conditions, but also depend on the atmospheric circulations and associated rainfall that may trigger drought to persist land-atmosphere feedbacks take place. The quantitative role of early (ESSM) trends, versus trends in other large-scale drivers (LS), explaining long-term warming have not been investigated so far. Using ...

Summer dormancy is an evolutionary response that some perennial cool-season grasses adopted as an avoidance strategy to escape summer drought and heat. It is correlated with superior survival after severe summer droughts in many perennial grass species originating from Mediterranean environments. Understanding the genetic mechanism and environmental determinants of summer dormancy is important ...

EVERY GREENKEEPER heaves a sigh of relief when he realizes that another summer, with all the worries that with it, has passed. There is always more -or less injury to fine turf on golf ccmrsee during the extreme summer weather atid usually some particular area of the country gets more than its share of turf trouble. This summer has probably set a record for the wide extent of putting green twrf...
