Allelopathic effects of Casuarina equisetifolia L. on seed germination of some crop plants and their associated weeds
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference)Casuarina equisetifolia L. is a widespread tree that has been known for its allelopathic potential causing biological inhibition on plant seed germination. Leaf extract of Casuarina equisetifolia L. was evaluated for its ... -
ANEUPLOIDY IN THE PEARL OYSTER PINCTADA RADIATA (LEACH, 1814): EVIDENCE FOR NONRANDOM CHROMOSOME LOSS AND GAIN IN MARINE BIVALVES
( Institute of Malacology , 2022 , Article)Aneuploidy, or presence of an abnormal number of chromosomes, has been commonly observed in marine bivalves. This phenomenon has also been shown to be negatively correlated with growth and survival rates in several species ... -
Anthropogenic related variations in the epibiotic biodiversity and age structure of the “Pearl Oyster” Pinctada radiata within the eulittoral zone of Qatar
( Elsevier , 2016 , Article)Abstract Oyster aggregations provide critical habitat that contain diverse communities, with epibiota and oysters sensitive to environmental disturbance. The monitoring of oysters and associated organisms has become an ... -
Are mangroves in arid environments isolated systems? Life-history and evidence of dietary contribution from inwelling in a mangrove-resident shrimp species
( Elsevier , 2013 , Article)The Arabian Gulf represents one of the more northerly extremes of mangrove distribution in the Indo-Pacific, and is populated only by Avicennia marina, due to its tolerance of high salinity and wide temperature extremes. ... -
Are offshore platforms a good candidate to restore functional diversity of reef fish communities in the Arabian Gulf?
( Elsevier B.V. , 2023 , Article)Human-made structures are ubiquitous in the marine realm. Complex structures such as oil and gas platforms may constitute a suitable habitat for species in areas where natural reefs have been highly degraded by coastal ... -
