Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali

Theses

The stratospheric ozone depletion and elevated solar UV-B radiation have a negative effect on living life forms. UV radiation is one of the unsafe components that cause hindrance to both flora and fauna on the earth. This will have important implications for ecosystem processes and food production. The present study has been designed with primary objective of the effect of UV-B radiation on five numbers of most cultivated Emirates varieties (i.e., BARHI, FRDWT, NBTSF, FRDRD and KHD). After 4 and 8 hrs/day UVB treatment the Shoot, Root and total Plant length, Total plant fresh weight, Shoot and Root ...

The Thorny Problem In A Changing Ocean : Responses Of The Coral-Eating Crown Of Thorns Starfish (Cots) To Ocean Warming And Acidification, And The Implications For Coral Reefs, Pamela Ziphillia Aro Kamya

Theses

Increases in anthropogenic emissions of carbon dioxide are causing unprecedented warming and acidification of the world’s oceans. These global changes in ocean conditions have profound impacts on marine organisms and ecosystems. One of the most critical ecosystems under threat from global climate change are coral reefs. Throughout the Indo-Pacific region declines in coral reef cover from climate change has been exacerbated population outbreaks of the coral-eating crown of thorns starfish (COTS), Acanthaster planci. While it is understood how corals will respond to ocean warming and acidification, there is no knowledge of how this predator of corals will fare in ...
